Lichess is an online chess platform where players can play against each other in different rating brackets. Our idea was to visualize the chess opening hierarchy by experience level on the Lichess platform catered to beginner to advanced chess players. Chess openings are specific sequences of moves played by both...
Cook County has high rate of vaccination across one of the largest populations in the country. But now that vaccine uptake is beginning to stagnate, what can Cook County do to close the gap? We used unsupervised learning to cluster Cook with 480 counties across the US, then used Tableau...
My submission seeks to describe the consequences of the Russian invasion of Ukraine on civilians using recent data from the United Nations. However, my work acknowledges the fallibility and lack of granularity of data collected during armed conflict, as well as the tendency of quantification to dehumanize those it describes....
Different cancers are dependent on distinct genes for their survival. The Broad institute previously ran assays on cancer cell lines that knocked out individual genes. Cell survival was subsequently measured to discover what genes were most essential to cancer survival. This dashboard uses the “essentiality” scores produced from these assays...
In this video of simulated galaxy formation there are three panels, each showing the same scene from a different perspective. The leftmost is a view of interstellar gas, the coldest (blue) of which will eventually form into stars like the Sun. In the middle panel, which shows what the Hubble...
On February 22, 2022, I gave a talk hosted by the African Studies Program of Georgetown University. Two days later, Russian battalions were sent across Ukraine’s borders by President Vladimir Putin. In real time, viewers around the world have seen immense distress unleashed on innocent citizens. In Africa, distress has...
Attitude control in quadrotor Unmanned Aerial Vehicle (UAV) systems is traditionally managed by optimal control loops tuned to minimize errors in performance. While robust, these loops perform sub-optimally in dynamic and unpredictable environments which inspire new interest in sophisticated solution and approaches such as reinforcement learning (RL) approaches which should...
The ability of a cell to regulate its mechanical properties is central to its function. Emerging evidence suggests that interactions between the cell nucleus and cytoskeleton influence cell mechanics through poorly understood mechanisms. Here we conduct quantitative confocal imaging to show that loss of A-type lamins tends to increase nuclear...

Abstract A significant component of the repetitive dynamics during locomotion in vertebrates is generated within the spinal cord. The legged locomotion of mammals is most likely controled by a hierarchical, multi-layer spinal network structure, while the axial circuitry generating the undulatory swimming motion of animals like lamprey is thought to...
Circadian rhythms — physiological, behavioral, and metabolic oscillations with an approximate 24-h period — are controlled by an evolutionarily conserved set of core clock genes operating at the transcriptional and protein level. Entrainable by Zeitgebers (external environmental stimuli such as light, temperature, and food) that modulate time-of-day specific functions, the...
This data was a part of a REDCap survey opened from 5/6/2020 to 7/7/2020. Potential participants with cerebral palsy and their families voluntarily responded to various questions about the motivators, barriers, and goals associated with the decision to participate in cerebral palsy research. Included in this work are the dataset...
Throughout the last two decades several scholars observed that present-day research into human genes rarely turns toward genes that had not already been extensively investigated in the past. Guided by hypotheses derived from studies of science and innovation, we present here a literature-wide data-driven meta-analysis to identify the specific scientific...
This thesis discussed how motifs of height and depth in Black literature highlight Black characters’ inability to form positive racial identities. The thesis uses three canonical pieces of Black literature, Passing, Native Son, and Plum Bun, to demonstrate that Black characters who try to reimagine White space are forced into...
The purpose of this research project was to highlight that there are different perspectives on mental health that stem from various experiences. All of these views should be valued and not discriminated against for any reason other than that they are different. As a child of Soviet Immigrants, I quickly...
This is the raw data for an article in the process of being published. The article's abstract is: There is evidence suggesting that during walking the whole body center-of-mass (COM) trajectory may be a control objective, a goal that the central nervous system chooses optimal solutions around to plan and...
In 2011, after just eighteen days, from January 25 to February 11, the Egyptian public overthrew the 30-year-long dictatorship of Hosni Mubarak. A decade afterward, we sought to have Egyptians reflect on the collective memory of those days. What fueled the revolution? Was it successful? Did it lose its way?...
A review of the literature demonstrates that being anonymous by wearing a mask has been hypothesized to create many psychological effects, but mainly deindividuation. Numerous distinct explanations have been suggested as to why that effect has come about.
Using an ethnographical approach and open-ended interviews, this study investigates through two...
Dass Gewalt ein intrinsisches Element moderner westlicher Gesellschaften ist, wurde von vielen politischen Theoretiker*innen dargelegt. Was aber ist Gewalt? Ist die Verhinderung von Lebenschancen Gewalt? Ist Gewalt eine Struktur? Gibt es eine Gewalt der Normen? Wie verhalten sich Politik und Gewalt? Kann der Staat Schutz vor Gewalt bieten? Wie unterscheidet...
Seit einigen Jahrzehnten – und heute mit neuer Vehemenz – gibt es von feministischer, postkolonialer und rassismustheoretischer Seite Interventionen in den philosophischen Kanon und das Selbstverständnis der Philosophie. Nicht nur stecken die klassischen philosophischen Texte voller misogyner und rassistischer Anekdoten und Andeutungen, sondern auch die scheinbar neutralen Begriffe und Themen,...
Anstelle von wöchentlichen Webex-Sitzungen arbeitet dieses Seminar verstärkt mit Podcasts. Zwischen de zweiwöchentlichen Web-Sitzungen lade ich Podcasts zur jeweiligen Seminarlektüre hoch, die Sie im Anschluss auf Moodle im Forum kommentieren oder wo ie Fragen zum Text stellen.
Background: Neural impairments that follow hemiparetic stroke may negatively affect passive muscle properties, further limiting recovery. However, factors such as hypertonia, spasticity, and botulinum neurotoxin (BoNT), a common clinical intervention, confound our understanding of muscle properties in chronic stroke.
Objective: To determine if muscle passive biomechanical properties are different following...
Why did political independence not lead to economic autonomy and sustained development which were confidently predicted by many development economists and nationalists in the 1950s and 1960s. Africa will not make sustainable progress in building democratic systems and fostering economic development until the continent acquires coherent, legitimate, and effective states....
By assessing infants’ movements, our research goal was to determine if particular movement characteristics are indicators for cerebral palsy (CP), a disorder caused by a brain injury to the fetus/infant that leads to impaired development of movement. Our research may contribute to developing an earlier diagnosis for CP, and therefore...
Codable robots, small electronic devices programmed with software or apps, have become popular toys for children to play with at home. During play, children learn about coding by programming their robot to move and behave however they choose. But given the novelty of coding, children may face impasses when coding...
Now more than ever, forecasting the outcomes of U.S. elections is an important and challenging task. Traditionally, statistical or political-science methods have been employed to better understand how individuals will vote. Our approach differs in that we use mathematical modeling. Adapting methods commonly used in epidemiology to understand biological disease...
Gender-based violence (GBV) is a prevalent issue on a global scale, but the effects of such violence upon Asian/Asian American communities in the United States is compounded by their immigrant, refugee, and/or other historically marginalized identities. While current literature recognizes GBV as a public health issue of equity and social...
An action potential (AP) is a shift in the membrane voltage of a neuron generally caused by a sudden ion influx, resulting in excitation, allowing for the cell to send signals across its neural network. Spontaneous excitation can be crucial for organizing neural circuits, especially in sensory modalities. For hearing...
he mapping of the human brain is one of the most challenging but important topics among the fields of research. The delicate, intertwined networks of neurons obstruct us from taking invasive measures to explore the wonders of the brain. Functional Magnetic Resonance Imaging (fMRI) is a possible non-invasive technique for...
Bacteria interact intimately with humans, from “good” bacteria that live in our bodies to “bad” pathogenic bacteria that cause disease. Pathogenic bacteria express virulence genes, which help bacteria invade and attack their host. The ability to control virulence gene expression would help us treat infection more effectively. Several virulence genes...
For over a hundred years, psychologists have sought to understand the role of spirituality in human behavior and experience, and how it might relate to features of personality. This study considered personal narration of spiritual experience and how it relates to the personality traits of Openness to Experience, Conscientiousness, Extraversion,...
Research finds people reproduce incorrect information provided by their collaborative partners. These “social contagion” effects largely studied memory for information introduced during experiments (e.g., word lists), rather than preexisting knowledge. This study extends the effects of social contagion of memory to social contagion of knowledge: Does what people know to...
During pregnancy, mothers undergo a range of physiological changes including shifting hormone levels, modified immune function, and reduced gut motility. These changes are necessary to meet the pregnant mother’s increased energy needs and inhibit rejection of the fetus. The gut microbiota (GM) – the community of microorganisms that live in...
Much insight into infants’ neuromotor development can be gleaned from their spontaneous movements. Specifically, a greater understanding of neuromotor development is valuable for the early diagnosis of cerebral palsy (CP), a neurological disorder resulting from brain injury or atypical development at an early age and is characterized by impaired movement...
Through framing, identical information can be portrayed in different ways. Existing literature finds that receiving positively framed information makes people more risk-averse than receiving negatively framed information, but disagreement remains on the strength of this effect and the conditions under which it occurs. In this study, 503 participants were surveyed...
When asked to imagine a computer scientist, males and females tend to report that they imagine a male. This perception can be detrimental for females’ computer science self-efficacy and may contribute to findings that as early as elementary school females are less interested in and less confident in their computing...
