Pi gets all the fanfare, but other numbers also deserve their own math holidays

Written by Manil Suri, professor of mathematics and statistics, UMBC

March 14 is celebrated as Pi Day because the date, when written as 3/14, matches the start of the decimal expansion 3.14159… of the most famous mathematical constant.

By itself, pi is simply a number, one among countless others between 3 and 4. What makes it famous is that it’s built into every circle you see – circumference equals pi times diameter – not to mention a range of other, unrelated contexts in nature, from the bell curve distribution to general relativity.

The true reason to celebrate Pi Day is that mathematics, which is a purely abstract subject, turns out to describe our universe so well. My book “The Big Bang of Numbers” explores how remarkably hardwired into our reality math is. Perhaps the most striking evidence comes from mathematical constants: those rare numbers, including pi, that break out of the pack by appearing so frequently – and often, unexpectedly – in natural phenomena and related equations, that mathematicians like me exalt them with special names and symbols.

So, what other mathematical constants are worth celebrating? Here are my proposals to start filling out the rest of the calendar.

The Golden Ratio

For January, I nominate the Golden Ratio, phi. Two quantities are said to be in this ratio if dividing the larger by the smaller quantity gives the same answer as dividing the sum of the two quantities by the larger quantity. Phi equals 1.618…, and since there’s no Jan. 61, we could celebrate it on Jan. 6.

First calculated by Euclid, this ratio was popularized by Italian mathematician Luca Pacioli, who wrote a book in 1509 extravagantly extolling its aesthetic properties. Supposedly, Leonardo da Vinci, who drew 60 drawings for this book, incorporated it into the dimensions of Mona Lisa’s features, a choice some claim is responsible for her beauty.

The first inkling that phi occurs in nature came from another Italian, Fibonacci, while studying how rabbits multiply. A common reproductive assumption was that each pair of rabbits begets another pair every month. Start with a single rabbit pair, and successive populations will then follow the sequence 1, 2, 4, 8, 16, 32, 64, 128, 256 and so on – that is, get multiplied by a monthly “growth ratio” of 2.

What Fibonacci observed, though, was that rabbits spent the first cycle reaching sexual maturity and only began reproducing after that. A single pair now gives the new, slower progression 1, 1, 2, 3, 5, 8, 13, 21, 34… instead. This is the famous sequence named after Fibonacci; notice that each population turns out to be the sum of its two predecessors.

Fibonacci’s rabbits don’t really double their population each generation – their growth ratio actually approaches the 1.618… of phi. (Image from ‘The Big Bang of Numbers’)

How does phi show up amid all these randy rabbits? Well, progressing through the sequence, you see that each number is about 1.6 times the previous one. In fact, this growth ratio keeps getting closer and closer to 1.618…. For instance, 21 equals about 1.615 times 13, and 34 equals about 1.619 times 21. This means the rabbits settle down to reproducing with a growth ratio that is no longer 2, but rather, gets closer and closer to the Golden Ratio.

Actual rabbits are unlikely to follow this rule precisely. For one, they have the unfortunate tendency to get eaten by predators. But the Fibonacci numbers – like 5, 8, 13 and so on – show up extensively in nature, like in the number of spirals you might see in a typical pine cone. And yes, phi itself makes a few appearances as well, perhaps most notably in the way leaves arrange themselves around a stem to maximize exposure to sunlight.

The constant ‘e’

February offers another blockbuster constant, Euler’s number e, which has the value 2.718…. So mark next Feb. 7 for the shindig.

To understand e, consider “doubling” growth again, but now in terms of the “population” of dollars in your bank account. By some miracle, your money in this example is earning you 100% interest, compounded each year. Each $1 invested becomes $2 at year’s end.

Suppose, however, the interest is compounded semiannually. Then 50% of the interest is credited midyear, giving you $1.50. You get the remaining 50% interest on this $1.50 at the end of the year, which works out to $0.75, giving you $2.25 ($1.50 + $0.75). So your investment gets multiplied by 2.25, rather than 2.

What if a war broke out between banks, each offering to compound the same 100% interest over shorter and more frequent intervals? Would the sky be the limit in terms of your payout? The answer is no. You could raise your growth ratio from 2 to about 2.718 – more precisely, to e – but no higher. Although you get more frequent credits, they have progressively diminishing returns.

In the late 17th century, the discovery of calculus led to a quantum leap in people’s ability to grapple with the universe. Math could now analyze anything that changed – which extended its domain to most phenomena in nature. The constant e is famous because of its iconic role in calculus: It turns out to be the most natural growth factor to track change. Consequently, it shows up in laws describing many natural processes – from population growth to radioactive decay. The constant e is a big part of calculus – and turns up in all kinds of natural phenomena.

The constant e is a big part of calculus – and turns up in all kinds of natural phenomena.

Next on our calendar of mathematical constants would come pi, of course, for March. My nominee for April is Feigenbaum’s constant delta, which equals 4.669… and measures how quickly growth processes spin off into chaos.

I’ll wait for my first batch to achieve official holiday status before going any further – happy to consider any candidates you want to nominate.

Meet a Retriever—Nate Dissmeyer ’07, alumni leader and recurring donor

Meet Nate Dissmeyer ’07, information systems, a program manager with Galapagos Federal Systems, providing Army IT support at the Aberdeen Proving Ground. Dissmeyer finds fulfillment in helping to develop IT professionals and supporting the Department of Defense community. And UMBC really gave him the skills to succeed in his position, he says. Dissmeyer, who is a recurring donor and a member of the Alumni Association Board of Directors (AABoD), found his way at UMBC through involvement with the Habitat for Humanity chapter and as a member of Triangle Fraternity. 

Q: What’s the one thing you’d want someone who hasn’t joined the UMBC community to know about the support you find here?

A: UMBC is simply a beacon of greatness. We attract some of the best minds, people, staff, leaders, and professors. Support is always present, always available even if you don’t necessarily seek it. There is a sense of if you succeed, we all succeed. Greatness doesn’t always come easy and there are times you’re going to struggle, but with a little grit and help from those around you, you will persevere and succeed.

Q: What brought you to UMBC in the first place?

A: I first came to UMBC for an Odyssey of the Mind competition in middle school. I remember walking around campus and just being amazed with the setting. When it was time to apply to colleges, UMBC was the only one I wanted to attend. It was the perfect size, not too small but not so large that I would be lost in the crowd or just a number on paper. UMBC was rising in the ranks as one of the best schools in the area, and I knew I was going to be challenged in my academic endeavors. Doing well here would help me succeed down the road.

Q: Tell us about the people who helped you grow at UMBC, and why their HOW made such a difference to you.

A: UMBC provided me much more than a place to get a degree. UMBC surrounded me with amazing people who have continued to influence me. My academic adviser encouraged me to make a degree change when I was struggling my sophomore year. A professor of my project management class who saw something in me to recommend Jim Collins’ Good to Great, which cultivated my management style.

I’ve gotten to see first hand how the money raised for the Alumni Endowment Scholarship helps our current students… Whether a semester’s worth of books, or one less job shift so they can spend more time at home raising their family; being able to help is rewarding.

Nate Dissmeyer '07

Through my involvement with the Habitat for Humanity chapter, I had the opportunity to help several families in West Baltimore and annually in Florida for our Spring Break build trip. I would have never dreamt that my Greek Life family would introduce me to my amazing wife (Sena Dissmeyer ’08, biochemistry and molecular biology), jump start my professional career, and form some of the most meaningful friendships I have. I am forever grateful for the impact, influence, and experiences UMBC has and will continue to give me.

Q: Tell us what you love about your role as an alumni leader.

A: Participating in the alumni organizations has been very special. I’ve thoroughly enjoyed the efforts to recognize amazing alumni and hearing their stories at the Alumni Awards. I would highly recommend current students to attend at least one event. I’ve also been so pleased to help award scholarships to students, whether raising money through the Chapter of Young Alumni or being part of the selection committee on the AABoD. 

Q: What drives you to support UMBC?

A: As a recurring donor, it’s easy to set up my monthly automatic donation, and I’ve gotten to see first hand how the money raised for the Alumni Endowment Scholarship helps our current students from all walks of life continue to achieve their academic success by removing some of the financial stress. Whether a semester’s worth of books, or one less job shift so they can spend more time at home raising their family; being able to help is rewarding. 

Q: Who in the community has inspired you or supported you, and how?

A: Honestly, a huge shoutout to Greg Simmons (M.P.P. ’04, vice president for Institutional Advancement) and his Office of Institutional Advancement team. Since joining the alumni groups, I’ve had the privilege of working with amazing staff and leaders. I never quite understood the depths of their work, but they do so much both visibly and behind the scenes. Now in my tenth year of consecutive giving, their hard work truly inspires me to participate and continue to contribute my skills and abilities for the betterment of UMBC.

UMBC’s greatest strength is its people. When people meet Retrievers and hear about the passion they bring, the relationships they create, the ways they support each other, and the commitment they have to inclusive excellence, they truly get a sense of our community. That’s what “Meet a Retriever” is all about.

Satellite data: The other type of smartphone data you might not know about

Co-written by Alicia Sabatino ’20, M.S. ’24, geography and environmental systems, UMBC.

When you think about location data on your mobile phone, tablet or laptop, what comes to mind? Mailing addresses? Postal codes? These data indicate where you live, where you work, and the places you visit.

When combined with other types of data over time, companies and governments use them to analyze your consumption patterns, occupation, education, health and financial status.

Turning location services off only prevents smartphone apps from receiving location data. Smartphones can still be located by cell towers and wireless networks when location services are switched off.

This was highlighted by German politician Malte Spitz over a decade ago when he sued his cellphone provider, Deutsche Telekom, for any personal data they had about him.

When the case was settled and he eventually received the data, Spitz found 35,000 references to his location. He was able to visually reconstruct his movements over the previous six months, demonstrating the relevance of data protection laws to the public.

But there is more. By using critical code and documentary research methods, we found that raw satellite location measurement data are perpetually created in our devices all the time.

Because satellite data are building blocks used by our phones to determine where we are, they don’t always get turned off — nor are they collected and treated the same way as location data.

Data outputs

Smartphones determine your location in several ways. The first way involves phones triangulating distances between cell towers or Wi-Fi routers.

The second way involves smartphones interacting with navigation satellites. When satellites pass overhead, they transmit signals to smartphones, which allows smartphones to calculate their own location. This process uses a specialized piece of hardware called the Global Navigation Satellite System (GNSS) chipset. Every smartphone has one.

When these GNSS chipsets calculate navigation satellite signals, they output data in two standardized formats (known as protocols or languages): the GNSS raw measurement protocol and the National Marine Electronics Association protocol (NMEA 0183).

GNSS raw measurements include data such as the distance between satellites and cellphones and measurements of the signal itself.

NMEA 0183 contains similar information to GNSS raw measurements, but also includes additional information such as satellite identification numbers, the number of satellites in a constellation, what country owns a satellite, and the position of a satellite.

NMEA 0183 was created and is governed by the NMEA, a not-for-profit lobby group that is also a marine electronics trade organization. The NMEA was formed at the 1957 New York Boat Show when boating equipment manufacturers decided to build stronger relationships within the electronic manufacturing industry.

In the decades since, the NMEA 0183 data standard has improved marine electronics communications and is now found on a wide variety of non-marine communications devices today, including smartphones.

Who has access to these data?

It is difficult to know who has access to data produced by these protocols. Access to NMEA protocols is only available under licence to businesses for a fee.

GNSS raw measurements, on the other hand, are a universal standard and can be read by different devices in the same way without a license. In 2016, Google allowed industries to have open access to it to foster innovation around device tracking accuracy, precision, analytics about how we move in real-time, and predictions about our movements in the future.

While automated processes can quietly harvest location data — like when a French-based company extracted location data from Salaat First, a Muslim prayer app — these data don’t need to be taken directly from smartphones to be exploited.

Data can be modelled, experimented with, or emulated in licensed devices in labs for innovation and algorithmic development.

Satellite-driven raw measurements from our devices were used to power global surveillance networks like STRIKE3, a now defunct European-led initiative that monitored and reported perceived threats to navigation satellites.

Data and citizen rights

Our research raises questions about how rights are protected in the midst of these practices. Citizens have little to no access to the data output from NMEA 0183 and GNSS raw measurements. Because of this, people are unable to negotiate the visibility of their data in these datasets.

The data output from NMEA 0183 and GNSS raw measurements flow unrestricted from every smartphone on the planet. Smartphones have unique identifiers — IMEI numbers — that are known to the tech ecosystem. They can be connected to a user’s personal details.

The flow of NMEA 0183 and GNSS data is invisible to the average person, meaning citizens are unsure of how these data are used, or with whom they are shared. Because of this, it’s impossible for people to challenge how their personal data are used.

As interest in the supposed security, entertainment and surveillance value of these protocols continue to grow, these protocols are increasingly susceptible to misuse by third-party developers.

But there is another layer to this: NMEA 0183 and GNSS raw measurements are standards in industries that offer products and services that many of us benefit from. The NMEA has foundations in safe passage at sea, making their data an important part of emergency services operations. GNSS raw measurements are also utilized for safety purposes.

Could solutions restrict the use of these data for life-critical situations only? Is there an oversight body that could assess what impacts industrial usage of these data might have upon smartphone owner rights and liberties? What about an audit led by civil society, who would be appropriately positioned to objectively inspect these issues to determine whether they might harm the public? For example, consider the way the federal privacy commissioner reviews app data activities.

Location data now flows constantly from GNSS chipsets. There is uncertainty about who is using these data, and for what purposes. Until industry and government reassure citizens that personal data are not being exploited and that rights are protected, these remain open questions.

Studying abroad is poised to make a post-pandemic comeback – here are 5 questions students who plan to study overseas should ask

Written by David L. Di Maria, associate vice provost for international education, UMBC

Before the pandemic struck in 2020, the number of U.S. students studying abroad had been pretty much rising steadily each year.

Whereas more than 154,000 students from the U.S. participated in study abroad programs during the 2000-2001 academic year, that number more than doubled – to over 347,000 – during the 2018-2019 academic year. That’s according to the Institute of International Education.

The global spread of COVID-19, however, brought the steady growth in study abroad to a screeching halt in early 2020. Students were evacuated from host countries and study abroad programs got canceledLockdowns and travel restrictions led the number of U.S. students studying abroad during the 2020-2021 academic year to plummet by 91% to just 14,549.

While official study abroad numbers for 2021-2022 are not yet published, there is reason to expect a rebound. A national survey conducted in April 2022 revealed that roughly 90% of colleges and universities were planning to offer some form of study abroad by the summer of that year.

As a university administrator who specializes in international education, I believe the number of students studying abroad will continue to rise. I see that as a positive development given the research that shows studying abroad supports academic successpromotes career readiness and prepares students to interact with people from other cultures. Moreover, increasing the number of U.S. students studying abroad supports U.S. foreign policy goals that rely on people-to-people exchanges and public diplomacy.

However, as studying abroad makes its comeback, much has changed with how study abroad programs operate. Below are five questions to ask when planning to study abroad in a post-pandemic world.

1. What is the Plan B in case my program gets disrupted?

In 2020, as students were recalled to the U.S. by their home institutions, a key concern was how students could remain on track for their degrees without losing both time and money due to the cancellations – which stemmed from reasons beyond their own control.

An important question for students to ask is how study abroad programs would ensure that they can continue their studies in case of a disruption, whether it’s caused by rare events, such as a pandemic or international conflict, but also more routine matters, such as a national strike.

2. Do I need extra insurance?

Students should not assume that their regular U.S. health insurance will provide the level of coverage needed while abroad. In fact, the cost of a medical evacuation can run as high as US$250,000.

Most study abroad programs offer, and many require, participants to enroll in an affordable international travel insurance policy. In addition to paying for medical expenses, benefits may include coverage for costs associated with trip cancellation, required periods of quarantine, and emergency evacuations. Additionally, the policy may provide non-insurance travel assistance services, such as helping to replace lost or stolen documents. Students should ask about the availability of these policies and know what is covered.

3. What are the host country restrictions?

At the height of the pandemic, countries’ COVID-19 policies ranged from status quo to complete lockdown. In some instances, travelers could be fined or jailed for failing to follow local restrictions. The U.S. Department of State created a web page with information on the COVID-19 restrictions of each country. While most countries have dialed back restrictions, it is still very important to review this information because these policies can affect a student’s ability to travel and participate in certain activities once they are abroad.

4. What are the latest travel risks?

While the Centers for Disease Control and Prevention provides data on traveling in the era of COVID-19, including risk ratings and vaccination recommendations by country, it is also important to understand how the pandemic may have influenced other risks, such as by contributing to political tensions and applying pressure to already fragile health care systems.

Students should review the country-specific information published by the State Department, as well as register for real-time updates from the local U.S. embassy. Additionally, students should inquire about other resources, such as in-country staff available to assist with emergencies, who may be available to support program participants once they are abroad.

5. What scholarships can help cover the cost?

Because study abroad programs were mostly paused for the past few years, the scholarship funds that colleges have dedicated to these programs may have been left largely untouched. Fund balances could be higher now and there may be a possibility to obtain a larger award than in years past. Students should inquire with their college’s study abroad and financial aid offices about scholarship opportunities. Such funding can vary greatly by program duration, location and other factors, so students should be flexible with their plans to receive the maximum award.

Whether or not their college offers generous scholarships for study abroad, students should also consider applying for external funding. The Fund for Education Abroad, an organization committed to increasing the number of underrepresented students studying abroad, maintains a listing of more than 20 dedicated scholarships. Additionally, the State Department compiles information on applying for study abroad programs and scholarships supported by the U.S. government. Some of these programs and scholarships are designed to lead to a federal job. The department also keeps a list of various scholarships from foreign governments.

Meet a Retriever: Basil Udo ’22, entrepreneur and bwtech@UMBC technologist

Meet Basil Udo ’22, biochemistry and molecular biology, an entrepreneur and technologist in the third cohort of bwtech@UMBC’s Maryland New Venture Fellowship for Cybersecurity program, where teams work together to create the commercially viable solutions the nation needs to secure physical and virtual infrastructures. Basil walks us through the timeline of creating his business venture as an undergraduate, support from campus leaders to help finesse his vision, his entrepreneurial award, and how he made the most of his UMBC connections to find a job in his area of industry. 

Q: How did you get involved with bwtech@UMBC?

A: In Spring 2022, I gained access to bwtech@UMBC’s CyberHive via the Student Idea Lab for my venture, Xeddy. At Xeddy, we are innovating the punch card experience with digital loyalty programs for restaurants and cafes. What I enjoy most about this work is the potential to impact many lives in a net positive way. In October, I was awarded a 2022 Student Entrepreneur Award at bwtech@UMBC’s Cyber & Tech Awards. 

Q: Tell us about your primary WHY, and how it led you to UMBC.

A: I came to UMBC because of a 2018 summer research experience with the Build a Bridge to STEM program. My team conducted research with Jeffrey Gardner, associate professor in biological sciences, where we developed and rendered designs for biomass containment devices and tested their efficiency in measuring the degradation of polysaccharides. Later that summer, my research team and I went on to present our findings at UMBC’s Summer Undergraduate Research Fest. Ultimately, this experience was an inflection point in my feelings of self-efficacy and interest in new information. 

Who is someone in the community who has supported you, and how?

a student stands in front of a bwtech@umbc sign for the research and entrepreneurial center

A: In 2021, I was actively practicing my elevator pitch around Xeddy and when the opportunity presented itself to share it with an audience, I did. It was the first day of my Introduction to Entrepreneurship class, and this led to me connecting with my professor, Scott Weber, outside of class. He introduced me to more resources on campus, specifically Kevin Fulmer, the director of the Alex. Brown Center for Entrepreneurship, where I received foundational support to materialize my ideas and tighten my pitch.

How have you taken your entrepreneurial skills to the next level?

A: I am a technologist in the third cohort of bwtech@UMBC’s Maryland New Venture Fellowship for Cybersecurity. Every week, we are introduced to new resources and left with actionable steps to take that further our internal company missions. This greatly appreciated added layer of accountability encourages myself and my team to strategically look past our launch.

Tell us about the people who helped you grow at UMBC, and why their HOW made such a difference to you.

A: In my last semester at UMBC, I virtually met with a science career advisor, Susan Hindle. She helped me rework my résumé and highlight my strongest attributes. A few weeks later, I grabbed lunch with a leader in bwtech’s community, and he suggested that I learn more about a company called Catalent Pharma Solutions.

Another few weeks went by, and I was passing by a Catalent information booth near the bookstore in The Commons. I recall making the conscious decision to return after my class to connect with the team of recruiters. Upon my arrival at the booth, I saw (and met for the first time in person) my career advisor, who then gave me a lovely introduction to the recruiters. In November, I received my offer letter to get started!

I enjoy heading over to UMBC’s main campus to get involved with entrepreneurial affairs… Exploring these opportunities from an alumnus perspective has given me an added appreciation for the resources and support that are active and growing in our community.

Basil Udo '22

I am now a manufacturing associate at Catalent. Every day I learn something new and it provides me with a way to support and enrich myself as I pursue my personal endeavors with Xeddy. Additionally, the exposure to corporate systems has introduced a new perspective on logistical efficiency, which makes me better at facilitating direction as a founder. 

What’s your favorite part of Retriever Nation?

A: Since I spend a lot of my time at the Research & Technology Park, I enjoy heading over to UMBC’s main campus to get involved with entrepreneurial affairs run by the Alex. Brown Center and volunteer events such as HackUMBC. Exploring these opportunities from an alumnus perspective has given me an added appreciation for the resources and support that are active and growing in our community.

What’s the one thing you’d want someone who hasn’t joined the UMBC community to know about the support you find here?

A: The entrepreneurial community at UMBC is growing and innovating each year. If you intentionally want to start a venture, UMBC will avidly support you. Starting with resources like the Alex. Brown Center, HackUMBC, and entrepreneurship classes will provide someone unsure of how to start with direction, potential cofounders, and info on the entrepreneurial mindset.

Mini creatures with mighty voices know their audience and focus on a single frequency

Written by Bernard Lohr, associate professor of biological sciences, UMBC

In the cloud forests of South America, amid the constant cacophony of bird and insect noise, a deafening blare pierces through the background from time to time. Belonging to the loudest known bird, the white bellbird, Procnias albus, this sound would be painful to humans listening nearby and capable of causing immediate hearing damage from about a yard away.

Listen to the world’s loudest bird call.

Made exclusively by males serenading females, these vocalizations can reach peak levels of more than 120 decibels on the sound pressure level scale (dB SPL), which is equivalent to a jet aircraft taking off from 100 yards awayThe female bellbird listens some distance from the male, presumably trading off being close enough to assess his quality as a mate without damaging her ears.

I study the hearing ability of animals and the sounds they make to communicate. A great number of calls exist throughout the animal kingdom – and many are used to attract mates or defend territories. Evolution has favored those able to make sounds efficiently. The louder and more focused the energy in the call and the closer in pitch it is to the intended listener’s optimal hearing range, the farther away a potential mate or rival will hear it.

Many large mammals, such as singing whales, roaring lions and rumbling elephants, produce loud low-pitched sounds that travel especially well through most habitats. Because of their petite physical size, small animals are not capable of making these far-reaching low-frequency sounds.

Ultrasonic calls

Human ears are most sensitive to the highest notes on a piano – about 4 kHz – a unit of measurement that is the physical metric for pitch. Anything above 20 kHz is considered ultrasonic – undetectable to human ears. But such sounds are not undetectable to all ears.

For example, the greater bulldog bat, Noctilio leporinus, can produce ultrasonic echolocation calls between 30 and 60 kHz when hunting prey and maneuvering during flight. These calls can also get incredibly loud – above 140 dB SPL.

Many other small mammals, including other bats, and even some primates such as tiny tarsiers, produce loud ultrasonic sounds humans can’t perceive. In part, these sounds can reach such volumes because their acoustic power is concentrated in a pure tone or single frequency.

Creating speakers

Insects are some of the smallest animals to produce loud sounds, chief among them the cicadas and the orthopterans, which include katydids, grasshoppers and crickets.

In North America, the robust conehead, Neoconocephalus robustus, a type of katydid, regularly surpasses 105 dB SPL. These calls are produced to attract mates and, like many such calls, are competing against a clamor of comparable sounds from similar species.

Some insects go one step further, amplifying their sounds by building the functional equivalent of audio speakers. Some tree crickets chew holes in leaves, place their vibrating wings in the opening and use the surrounding leaf as a baffle to prevent the loss of sound energy around the edges of their wings.

Mole crickets, Gryllotalpa vineae, go even further by constructing a burrow that acts like a wind instrument, creating a cavity of vibrating air that amplifies the sound energy they produce. These crickets’ songs can travel almost half a mile (0.8 kilometer).

Irksome invaders

The official mascot of Puerto Rico is a 1-to-2-inch (2-5-centimeter) frog called the coquí, Eleutherodactylus coqui, whose call is a combination of two pure tones – “ko” and “kee,” from which it gets its name. At 114-120 dB SPL, the frog’s calls are so loud they actually must protect their own hearing when vocalizing, by increasing the air pressure inside their middle ear.

Unfortunately, in the past few decades humans have accidentally introduced the coquí to a number of areas outside their native range, in particular the Hawaiian islands, where they have no natural predators and have become invasive pests. Since coquí calls are within an octave of humans’ best hearing – and they’re nocturnal – many Hawaiians suffer sleep disruptions because of the tiny frogs.

So even if you’re small, it’s not impossible to make yourself heard. You just have to blast all your acoustic energy in a single frequency, and hit the sweet spot of your audience’s hearing.

Organ-on-a-chip models allow researchers to conduct studies closer to real-life conditions – and possibly grease the drug development pipeline

Chengpeng Chen, Assistant Professor of Chemistry and Biochemistry, UMBC

Bringing a new drug to market costs billions of dollars and can take over a decade. These high monetary and time investments are both strong contributors to today’s skyrocketing health care costs and significant obstacles to delivering new therapies to patients. One big reason behind these barriers is the lab models researchers use to develop drugs in the first place.

Preclinical trials, or studies that test a drug’s efficacy and toxicity before it enters clinical trials in people, are mainly conducted on cell cultures and animals. Both are limited by their poor ability to mimic the conditions of the human body. Cell cultures in a petri dish are unable to replicate every aspect of tissue function, such as how cells interact in the body or the dynamics of living organs. And animals are not humans – even small genetic differences between species can be amplified to major physiological differences.

Fewer than 8% of successful animal studies for cancer therapies make it to human clinical trials. Because animal models often fail to predict drug effects in human clinical trials, these late-stage failures can significantly drive up both costs and patient health risks.

To address this translation problem, researchers have been developing a promising model that can more closely mimic the human body – organ-on-a-chip.

As an analytical chemist, I have been working to develop organ and tissue models that avoid the simplicity of common cell cultures and the discrepancies of animal models. I believe that, with further development, organs-on-chips can help researchers study diseases and test drugs in conditions that are closer to real life.

Organs-on-chips offer an alternative model for early-phase biomedical research.

What are organs-on-chips?

In the late 1990s, researchers figured out a way to layer elastic polymers to control and examine fluids at a microscopic level. This launched the field of microfluidics, which for the biomedical sciences involves the use of devices that can mimic the dynamic flow of fluids in the body, such as blood.

Advances in microfluidics have provided researchers a platform to culture cells that function more closely to how they would in the human body, specifically with organs-on-chips. The “chip” refers to the microfluidic device that encases the cells. They’re commonly made using the same technology as computer chips.

Not only do organs-on-chips mimic blood flow in the body, these platforms have microchambers that allow researchers to integrate multiple types of cells to mimic the diverse range of cell types normally present in an organ. The fluid flow connects these multiple cell types, allowing researchers to study how they interact with each other.

Microfluidics can be used for many applications in biological research.

This technology can overcome the limitations of both static cell cultures and animal studies in several ways. First, the presence of fluid flowing in the model allows it to mimic both what a cell experiences in the body, such as how it receives nutrients and removes wastes, and how a drug will move in the blood and interact with multiple types of cells. The ability to control fluid flow also enables researchers to fine-tune the optimal dosing for a particular drug.

The lung-on-a-chip model, for instance, is able to integrate both the mechanical and physical qualities of a living human lung. It’s able to mimic the dilation and contraction, or inhalation and exhalation, of the lung and simulate the interface between the lung and air. The ability to replicate these qualities allows researchers to better study lung impairment across different factors.

Bringing organs-on-chips to scale

While organ-on-a-chip pushes the boundaries of early-stage pharmaceutical research, the technology has not been widely integrated into drug development pipelines. I believe that a core obstacle for wide adoption of such chips is its high complexity and low practicality.

Current organ-on-a-chip models are difficult for the average scientist to use. Also, because most models are single-use and allow only one input, which limits what researchers can study at a given time, they are both expensive and time- and labor-intensive to implement. The high investments required to use these models might dampen enthusiasm to adopt them. After all, researchers often use the least complex models available for preclinical studies to reduce time and cost.

Lowering the technical bar to make and use organs-on-chips is critical to allowing the entire research community to take full advantage of their benefits. But this does not necessarily require simplifying the models. My lab, for example, has designed various “plug-and-play” tissue chips that are standardized and modular, allowing researchers to readily assemble premade parts to run their experiments.

The advent of 3D printing has also significantly facilitated the development of organ-on-a-chip, allowing researchers to directly manufacture entire tissue and organ models on chips. 3D printing is ideal for fast prototyping and design-sharing between users and also makes it easy for mass production of standardized materials.

I believe that organs-on-chips hold the potential to enable breakthroughs in drug discovery and allow researchers to better understand how organs function in health and disease. Increasing this technology’s accessibility could help take the model out of development in the lab and let it make its mark on the biomedical industry.

FTX’s collapse mirrors an infamous 18th century British financial scandal

Amy Froide, professor of history, UMBC

Enron. Bernie Madoff. FTX.

In modern capitalism, it seems as if stories of companies and managers who engage in fraud and swindle their investors occur like the changing of the seasons.

In fact, these scandals can be traced back to the origins of publicly traded companies, when the first stockbrokers bought and sold company shares and government securities in the coffee houses of London’s Exchange Alley during the 1700s.

As a historian of 18th century finance, I am struck by the similarities between what’s known as the Charitable Corporation Scandal and the recent collapse of FTX.

A noble cause

The Charitable Corporation was established in London in 1707 with the noble mission of providing “relief of the industrious poor by assisting them with small sums at legal interest.”

Essentially, it sought to provide low-interest loans to poor tradesmen, shielding them from predatory pawnbrokers who charged as much as 30% interest. The corporation made loans available at the rate of 5% in return for a pledge of property for security.

The Charitable Corporation was modeled on Monti di Pietà, a charitable institution of credit established in Catholic countries during the Renaissance era to combat usury, or high rates of interest.

Unlike the Monti di Pietà, however, the British version – despite its name – wasn’t a nonprofit. Instead, it was a business venture. The enterprise was funded by offering shares to investors who, in return, would make money while doing good. Under its original mission, it was like an 18th century version of today’s socially responsible investing, or “sustainable investment funds.”

Raiding the fund

In 1725, the Charitable Corporation diverted from its original mission when a new board of directors took over.

These men turned the corporation into their own piggy bank, taking money from it to buy shares and prop up their other companies. At the same time, the company’s employees began to engage in fraud: Safety checks ceased, books were kept irregularly and pledges went unrecorded.

Investigators would ultimately find that £400,000 or more in capital was missing – roughly $108 million in today’s U.S. dollars.

In the autumn of 1731, rumors began to circulate about the solvency of the Charitable Corporation. The warehouse keeper at the time, John Thomson, who was in charge of all loans and pledges but also in league with the five fraudulent directors, hid the company’s books and fled the country.

At the shareholders’ quarterly meeting, they found that money, pledges and accounts had all gone missing. At this point, the proprietors of the Charitable Corporation stock appealed to the British Parliament for redress. One-third of those who petitioned were women, a proportion that equaled the percentage of women who held shares in the Charitable Corporation.

Many women were drawn to the corporation because of its public mission in providing small loans to working people. It’s also possible that they had been intentionally targeted for fraud.

The parliamentary investigation led to various charges being leveled against both managers and employees of the Charitable Corporation. Many of them were forced to appear before Parliament and were arrested if they did not. The managers and employees deemed most responsible for the 1732 fraud, such as William Burroughs, had their assets seized and inventoried in order to help pay back the shareholder losses.

Bankruptcy proceedings were started against the banker and broker, George Robinson, and the warehouse keeper, Thomson. Both Sir Robert Sutton and Sir Archibald Grant were expelled as members of the House of Commons, with Grant being prevented from leaving the country and Sutton ultimately prosecuted in several courts.

In the end, the shareholders received a partial government bailout – Parliament authorized a lottery that reimbursed only 40% of what the corporation’s creditors had lost.

The risks of concentrated power

There are several key characteristics that stand out in the collapses of both the Charitable Corporation and FTX. Both companies were offering something new or venturing into a new sector. In the former’s case, it was microloans. In FTX’s case, it was cryptocurrency.

Meanwhile, the management of both ventures was centralized in the hands of just a few people. The Charitable Corporation got into trouble when it reduced its directors from 12 to five and when it consolidated most of its loan business in the hands of one employee – namely, Thomson. FTX’s example is even more extreme, with founder Sam Bankman-Fried calling all the shots.

In both cases, the key fraud was using the assets of one company to prop up another company managed by the same people. For example, in 1732, the corporation’s directors bought stock in the York Buildings Company, in which many of them were also involved. They hoped to juice stock prices. When that didn’t happen, they realized they couldn’t cover what they had taken out of the Charitable Corporation’s funds.

Fast forward nearly 300 years, and a similar story seems to have played out. Bankman-Fried allegedly took money out his customer accounts in FTX to cover his cryptocurrency trading firm, Alameda Research.

News of both frauds also came as a surprise, with little advance warning. Part of this is due to the ways in which managers were well respected and well connected to both politicians and the financial world. Few public figures mistrusted them, and this proved to be a useful screen for deceit.

I would also argue that in both cases the company’s connection to philanthropy lent it another level of cover. The Charitable Corporation’s very name announced its altruism. And even after the scandal subsided, commentators pointed out that the original business of microlending was useful. FTX’s founder Bankman-Fried is an advocate of effective altruism and has argued that it was useful for him and his companies to make lots of money so he could give it away to what he deemed effective causes.

After the Charitable Corporation’s collapse in 1732, Parliament didn’t institute any regulation that would prevent such a fraud from happening again.

A tradition of loose oversight and regulations has been the hallmark of Anglo-American capitalism. If the response to the 2008 financial crash is any indication of what will come in the wake of FTX’s collapse, it’s possible that some bad actors, like Bankman-Fried, will be punished. But any regulation will be undone at the first opportunity – or never put in place to begin with.

Finding Joy in the Democratic Process

On a Tuesday evening in early November, Main Street in The Commons was uncommonly crowded. Hundreds of democratically-minded students eagerly—and perhaps, anxiously—milled around watching the 2022 mid-term election returns. Dilnaz Hasim ’25, economics, found the scene fitting, saying, “Election Night Extravaganza is supposed to be experienced as a community, rather than as a single person, because when you make a vote, you’re making it for the whole community.”

Jointly hosted by the Center for Democracy and Civic Life, the Student Government Association (SGA), and the Graduate Student Association, the campus-based election event has been around since 2004. Students from every political affiliation bonded over a breakfast buffet and made room for bipartisan conversations in multiple breakout spaces. Other rooms had craft tables set up for students to creatively distract themselves while results rolled in.

As exciting as this night is, it’s only one part of efforts put forth throughout the year by the Center for Democracy and Civic Life to engage students in the day-to-day processes of democratic involvement. Leading up to elections, students are encouraged to “cast your whole vote”—an idea from Henry David Thoreau’s essay on civil disobedience—to commit fully to building strong, inclusive, just communities in which everyone can thrive. Following elections, students, staff, and faculty can take part in Together Beyond November discussions to talk about the election outcomes and envision a common future.

In late November 2022, the ALL IN Campus Democracy Challenge released the results of its national student voter pledge competition. UMBC finished at #4 in the nation in the number of students pledging to vote in Election 2022, moving our campus community up from #9 in 2020.

Musa Jafri ’24, political science, SGA’s director of civic engagement, was heartened by the turnout. “Democracy doesn’t end at the voting booth,” said Jafri, who is also co-chair of the University System of Maryland Student Civic Leaders Committee. “There’s so much more we can do as we watch the results and come together as a community. Even after whatever happens, we have fellow Retrievers coming together, watching the results, having food, and playing games.”

Another one of the event organizers, Meghna Chandrasekaran ’25, biology, hosted a social takeover during the night, interviewing her fellow students about their civic engagement. Many mentioned feeling the need to have their voices heard on issues they cared about. To wrap up the evening, Chandrasekaran said, “Election Night Extravaganza is an event to celebrate that we did come out. We had one job as citizens to come out and vote, express our concerns about certain things, and show that we are part of the process.”

To read more about engaging college students in everyday democratic practices, check out an extended Q&A with Musa Jafri, Sunil Dasgupta, professor of political science, and founder and host of the podcast “I Hate Politics,” and David Hoffman, Ph.D. ’13, language, literacy, and culture, the director of UMBC’s Center for Democracy and Civic Life.

Hang Ten with New Friends

When UMBC’s volleyball team headed to the University of Southern California (USC) for a tournament, Athletics reached out and invited West Coast Retrievers to an LA happy hour before the game. Eager to reconnect with their alma mater and meet other alumni in the area, folks gathered together and new friendships were formed. 

Despite the decades between their UMBC experiences, Matt Sheriff ’00, political science, and Nathenael Dereb ’21, computer science, bonded over a quintessential California connection—surfing. Specifically, Dereb, a recent relocator, wanted to learn how and Sheriff, who’s been on the West Coast for years, had the skills to teach. Since then, the pair has been meeting before work in the mornings catching the waves. They carved out some time to share the experience with UMBC Magazine.

Retrievers gathered for a West Coast happy hour.

UMBC Magazine: We know how you two met—can you tell us how you hit it off?

Sheriff: I attended graduate business school at USC, so when I read about a tournament volleyball game at USC that the UMBC team was invited to attend, I was simply amazed that my undergrad school was coming to USC. At the alumni pre-party, I met Nate Dereb, who, like me, also relocated from Maryland to LA. He was interested in learning to surf, so I’ve been introducing him to the sport when our schedules align. The beauty of living in Los Angeles is we can surf in the morning and be at work by 9 a.m., even earlier if necessary!

UMBC Magazine: What are your best surf tips?

Dereb and Sheriff connected at the USC volleyball tournament.

Sheriff: Take it slow in terms of expectations and remind yourself that the best surfer is the one having the most fun.

UMBC Magazine: How was the change from Maryland to California?

Dereb: Relocating across the country to a city I’ve never been before was an overwhelming experience, but I was fortunate to have my family around me during my relocation. One of the shocking things was finding myself outside only in shorts and a shirt in February! I’m still amazed by that.

UMBC Magazine: What are you up to now?

Sheriff: I’m a senior advisor at Southern California Edison where I lead regulatory economics projects and represent the company before the California Public Utilities Commission as an expert witness. Most of my work is finance-related but the communication and analytical skills I learned at UMBC are immensely helpful.

Dereb: I am working as a software engineer at Adobe within the analytics organization. On the side, I’m still maintaining and adding data for the platform I built during my senior year that assists students and faculty in retrieving data regarding course grades, course evaluations, and professors at UMBC.

UMBC Magazine: What was your experience at UMBC like? 

Dereb: My involvement in the Center for Women in Technology organization, as a Cyber Scholar, is an experience I will always cherish. I was also fortunate to win several awards and scholarships, get multiple internship opportunities, become a teaching fellow for Computer Science 202, and do innovative research as part of the Interactive Robotics and Language lab on campus. I am a proud Retriever!

Sheriff: More than anything I feel like I grew into a young adult who was ready for the world.

Unstuck in TimePeeling Back Layers Through Art

As a visual artist, Monique Crabb, M.F.A. ’22, intermedia and digital arts, draws from her environment quite literally—producing textile-based artworks colored with the rich hues of plants and objects around her. This fall, she spent a month in residency at the Baltimore County Public Library, teaching workshops and engaging with library users as she created new work inspired by her surroundings. These are her reflections from that experience.

One of the most calming places to be in is a public library surrounded by people’s research, stories, and history of every place and culture from almost every perspective imaginable. At times, the amount of knowledge at my fingertips can feel daunting knowing I’ll never be able to take it all in. I’m reminded of a scene in the ’80s movie My Stepmother Is an Alien, when the main character Celeste, played by Kim Basinger, travels to earth in a model’s body to conduct research on human life and discovers books. She’s able to retain the books’ information instantly through osmosis, spanning the gamut of human emotions, and is starved for more. This scene has imprinted itself in my mind as a superpower I wish I had. 

Growing up in a working class neighborhood to a mom who would every weekend pull open the large rolling door to our garage for the permanently set-up sale of our used things, and a father who worked various jobs and seemingly was never around, I spent most of my time outside of school on the streets, at friends’ homes, or playing in the woods. My parents did not engage much with books, the arts, or academia; I was mostly influenced by pop culture. 

As I got older, books came to me at very specific times in my life to change my perspective and help me find my place in the world of things. One of those times was my junior year in high school when my English teacher gave the class a list of authors to pick from for a book report and I selected Kurt Vonnegut, solely on the fact that his name sounded cool and he shared a first name with Kurt Cobain. I then found myself sitting on the floor of my school’s library absorbed by the opening line of Slaughterhouse-Five: “All this happened, more or less.”

The rest of the book was an eye-opening view of one person’s experience in the world during a time so far removed from my own, yet with relatable philosophical ideas with quotes like, “All time is all time. It does not change. It does not lend itself to warnings or explanations. It simply is. Take it moment by moment, and you will find that we are all, as I’ve said before, bugs in amber.” Books allow us to travel through time and place to help us find meaning in our lives, which is a magical experience that visual arts achieves just as profoundly.

The Baltimore County Public Library month-long Artist in Residence program was a gift to take part in. Each week I walked through a sea of books and would greet the librarians on my way to their maker space, The Hive. Being there allowed me the time and space to focus on one project.

I also had the opportunity to engage with a community outside of my own through two workshops I gave on eco-printing and dyeing with food waste as well as having the studio space open to visitors while I was working. On my lunch breaks I would browse books and take walks, once visiting the nearest cemetery and other times just taking in the colors and patterns from the intersecting relationship of plants and human-made constructions in the area. 

During my time in residency, I started a project using secondhand vintage linens made with open cut and intricately detailed hand and machine embroidery. I either cut up or used the entire napkin, handkerchief, or tablecloth and machine-pieced them together using pojagi, a Korean form of quilting that creates a seam on both sides of the pliable plane. These textile objects, often made by women, were and continue to be so precious that the folds and creases in them become deep from decades of being stored away unused.

I was drawn to bringing these objects out of storage, unfolding, and piecing one to the other to create a frankensteinian curtain that was large and would present as a confrontation in the middle of a room. I hadn’t fully unraveled the idea, but I knew if I put in the work that richer layers of context would reveal themselves.

Toward the end of my residency I had a library visitor come through and we chatted for a while about art, the artist’s process, and the meaning behind what is made. It was during this exchange that I had a lightbulb moment for my project of painting cyanotype directly onto the napkins and exposing stark images of tools used in the domestic world like a toilet brush. Adding this layer of context expanded my exploration of materials from domestic life by bringing attention and exposing the hidden labor behind the undervalued role of homemaker, woman, and caregiver. 

It’s essential to my growth as an artist to be in new environments and around new people as well as the opportunity to step back from being so deeply inside of my artwork by engaging with communities outside of my own. Meeting the folks who took my workshops and the ones who came through the studio to ask questions about what I was working on reminded me of the importance of my role as an artist. I believe our stories connect us and often find that the narratives I encounter, whether in person or from books, inform and enrich my practice in ways I could never do alone.
