Turning Science Fiction Into Reality: Enhanced Motor Learning For Prosthetic Limbs, Makayla Conley

The Yale Undergraduate Research Journal

In science fiction, prosthetic limbs appear as seamless extensions of the human body that function as if the limbs were made of flesh and bone. With recent technological and scientific advancements, the prosthetic limbs of today are beginning to resemble those we once only imagined. Patients are now able to perform simple, everyday tasks like drinking from a glass of water. However, there are many limitations to this technology, including lack of fine motor movement, absence of reflexes, and missing sensory feedback from the prosthetic limb. These restrictions prohibit prosthetics patients from having the same experience as someone with a …

Decolonization: The Litmus Test Of The Human Rights Framework, Isiuwa Omoigui

The Yale Undergraduate Research Journal

This literature review examines the complicated relationship between anticolonial activism and the human rights framework that emerged in the wake of the Second World War. I contextualize the scholarly debate on the tension between conceptions of human rights as an individual entitlement and the collectivist nature of African anticolonial struggles. The universalism of the human rights framework endures the harsh light of critique, given its emergence from the twentieth-century European experience of genocide and great powers’ competing commitments to democracy and empire. The crimes against humanity committed in the name of colonial conquest and rule challenge the great powers’ moral …

Returning To The Gender Gap In College Major: How Much Can Pre- College Skills Explain?, Nathalie Beauchamps

The Yale Undergraduate Research Journal

The gender wage gap in the United States is a well-known phenomenon and researchers across many disciplines have tried to pinpoint its cause. One popular explanation is the gender gap in college major choice; however, it is still unknown why women tend to major in so-called soft sciences and men in hard sciences. This paper builds upon Speer (2017)’s work studying the gender gap in major choice as explained by test scores. Rather than utilizing OLS regressions, I employ a Kitagawa-Oaxaca-Blinder decomposition method, which also shows how unspecified discrimination works for or against women (or men) in how much their …

The War On Fire: Construction Of Enemies And The U.S. Forest Service, Isabel Kirsch

The Yale Undergraduate Research Journal

I analyze the parallel constructions of the institution of the United States Forest Service and the idea of fire as a public enemy in the first half of the twentieth century. From where did this fire-as-enemy construction emerge, and what purpose did it serve? I draw extensively from Yale collections for my research, including glass slides of early-1900s forest fire prevention posters, a pamphlet of eerie children’s songs from 1928 with violent language about punishing those who start forest fires, and a Yale School of Forestry student’s 1934 thesis. I argue that equating forest fire with a public enemy has …

Examining Variations In Community Benefit Generation Across Namibian Conservancies, Amanda Zhang

The Yale Undergraduate Research Journal

Centered around Namibia’s Community Based Natural Resource Management (CBNRM) program, this analysis explores varying levels of community benefit generation across 51 of Namibia’s conservancies by comparing benefits across four conservancy subsets and using multiple linear regressions (MLRs) to examine relationships between selected conservancy characteristics and benefit generation. The statistically significant models predict that the presence of one additional major species is linked to an additional $N 1.458 in meat value per capita, $N 0.543 in conservancy wage per employee, and 0.661 in community game guard employment. While there appears to be a positive correlation between the number of species and …

Altering Sensory Learning By Chronic Inactivation Of Vip Interneurons, Christopher Alba, Hannah Selwyn, Katie Ferguson, Jessica Cardin

The Yale Undergraduate Research Journal

Vasoactive intestinal polypeptide-expressing interneurons (VIP-INs) play a key role in the regulation of cortical circuits and are implicated in perceptual function and psychiatric disease. However, their role in perceptual augmentation and learning remains understudied. We performed chronic, localized ablation of VIP-INs in the primary visual cortex of adult mice using caspase-induced apoptosis to better understand how VIP-INs contribute to visual perception and the ability to learn a visual detection task. We find that chronic VIP-IN ablation does not affect naïve performance on a full-screen visual contrast detection task. However, mice with suppressed levels of VIP-INs achieved their final expert state …

The Keiretsu Advantage: How Japanese Automakers Thwarted American Competition, Jasper Boers

The Yale Undergraduate Research Journal

Today, Japan’s auto industry is renowned for its dominance of foreign markets. Japanese cars are cheap and fuel-efficient, undercutting larger, more expensive automobiles from Europe and America. Scholarship on recent Japanese industrial development tends to prioritize a ‘developmental state’ and robust industrial policy in shielding Japanese manufacturers from trade liberalization. This paper will argue that, while the industrial policy steered by the Ministry of International Trade and Industry (MITI) played a significant role in advancing the interests of the Japanese auto industry, it was ultimately the unique trust-based keiretsu conglomerate structure that gave Japanese auto producers a comparative advantage vis-à-vis …

Russian Peasants In Tolstoy’S War And Peace - Idealized And Instrumentalized, Antonia Seyfarth

The Yale Undergraduate Research Journal

In War and Peace, Tolstoy challenges Western European notions of Russian backwardness and ‘barbarity’ through his depiction of the virtuousness, spiritual wisdom, and rich cultural traditions of the common Russian people. This idealized portrayal of Russian peasants and soldiers is essential to Tolstoy’s construction of a Russian national myth that unites members of all social classes behind a shared set of values. However, in turning the Russian peasantry into idealized, oversimplified caricatures that lack individuality, complexity, agency, and the ability for critical thought, Tolstoy reduces these characters to mere instruments that provide morally edifying lessons to Russia’s elites. This imposition …

High-Spatial-Resolution Transcriptomic Map Of The Mouse Lymph Node Microenvironment Using Deterministic Barcoding, Archibald Enninful, Yang Liu, Rong Fan

The Yale Undergraduate Research Journal

Spatial transcriptomics is an emerging approach which characterizes gene expression profiles for a more nuanced understanding of biological processes at a tissue level. This offers significant advantages over traditional omics which require the digestion of tissues and subsequent isolation of cells, during which the spatial information is completely lost. Lymph nodes are an integral part of the immune system and an in-depth analysis of its spatial organization will provide useful insights which can be applicable in the development of novel immunotherapies. In this study, the mouse lymph node is characterized using the newly developed microfluidic-based approach, Deterministic Barcoding in Tissue …

Designing A Microsecond-Long On-Chip Microwave Delay Line Using Srtio3 Dielectricity, Kazemi Adachi, Mingrui Xu, Hong Tang

The Yale Undergraduate Research Journal

The delay line is a fundamental circuit design component which slows down a signal with minimal attenuation to provide delay effects, with applications that include interferometry and signal filtering. Cryogenic superconducting delay lines can be less lossy than their regularly conducting counterparts. Scientists can engineer microwave photos with coherence times of several microseconds (us), longer than current on-chip delays. We utilize the high dielectric constant (>10^4) of strontium titanate at cryogenic temperatures to slow own signal propagation on a coplanar waveguide. Here, we present a design for an on-chip 5 (us) superconducting delay line ad 5 GHz with small …

A Midsummer Night’S Vr: An Exploration Of Virtual Reality Theater, Paige Hann, Nathan Roberts

The Yale Undergraduate Research Journal

Virtual reality (VR) is a medium predicated on immersivity. It therefore has implications for a similarly immersive field – live theater. The benefits of live theater are numerous. However, not everyone has the same access to theater for a variety of reasons, including cost and mental and physical health. Could VR serve as a legitimate alternative to live theater? Investigating this question, we utilized the resources of the Yale’s CCAM to create a virtual reality adaptation of A Midsummer Night’s Dream by William Shakespeare. Research shows that our brains process VR differently from either real-world stimulus or two-dimensional monitors. VR …

Euroasian Journal of Semiconductors Science and Engineering

This article shows that the Fermi levels of a nanoscale semiconductor in a quantizing magnetic field are quantized. A method is proposed for calculating the Fermi energy oscillations for a two-dimensional electron gas at different magnetic fields and temperatures. An analytical expression is obtained for calculating the Fermi-Dirac distribution function at high temperatures and weak magnetic fields. With the help of the proposed formula, the experimental results in nanoscale semiconductor structures are investigated. Using formula, Fermi energy oscillations are explained for two-dimensional electron gases in quantum wells (quantum wells, mainly GaAs/GaAlAs heterostructures) with a parabolic dispersion law

Influence Of The Effective Mass Of The Density Of The State On The Temperature Dependence Of The Band Band Width In Solid Solutions P-Bi2-Xsbxte3-Ysey, Sharibaev N.Y., Dadamirzaev M.G., Sharifbaev R.N.

Euroasian Journal of Semiconductors Science and Engineering

The temperature dependence of the energy spectrum of semiconductors is well explained by the thermal broadening of discrete energy spectra. The temperature dependence of the band gap is considered as broadening of the energy states of the conduction and valence bands. In these works, it was assumed that the effective mass of the density of states does not depend on temperature. However, as experiments have shown, the effective mass of the density of states depends on temperature. These changes in the effective mass change the temperature dependence of the band gap.
