Assessing Developmental Neurotoxicity Due To Pyrethroid Insecticide Exposure In C. Elegans, Katharine Boyd, Timothy A. Crombie

Biomedical Engineering and Sciences Student Publications

Pyrethroids are a type of insecticide widely used in agriculture and public health programs. These insecticides disrupt neuronal signaling in target insects through voltage-gated sodium channels and have been linked to cardiovascular and neurological disease in humans.The nervous system of the nematode Caenorhabditis elegans is fully mapped, and specific behavioral circuits can be tested, making it a powerful model for studying neurotoxicity. Because the primary target of pyrethroids is not conserved in C. elegans, secondary mechanisms of pyrethroid neurotoxicity can be identified by testing whether specific behavioral circuits are affected.

The True Interstellar Anisotropy Of 13 Tev Cosmic Rays, Matthew Conde

Aerospace, Physics, and Space Science Student Publications

Cosmic rays (CRs) are high-energy particles; bare atomic nuclei, with varying origins and energy levels. Research in this field is focused on identifying potential origins, understanding transport mechanisms faced on their journey to Earth, and interpreting the angular structure of incident CRs. One obstacle of this research is the trajectory modulation induced by the heliosphere during the CRs’ journey. In this work we employ a method to reconstruct the properties of CRs as they were at the local interstellar medium (LISM) by means of a nonlinear model fit to the map at Earth. Another obstacle is the time-averaging used to …

Gamma Ray Burst Afterglow Slopes, Brian Robbins

Aerospace, Physics, and Space Science Student Publications

The standard models for gamma ray bursts (GRBs) typically assume that shockaccelerated electrons follow a power law distribution of energies. However, this behavior is not what some gamma ray bursts show. In this project, it is suggested that the presence of thermal electrons causes temporal and spectral structure across the afterglow, which is significantly different from models assuming a pure power-law distribution of electrons. To model the afterglows, we decide on a large number of samples of GRBs from the Swift database and obtain the temporal and spectral indices at arbitrary times. By finding the temporal and spectral indices at …

Automatic Determination Of Mechanical Properties From Molecular Dynamic Stress-Strain Curves Using Regression Fringe Response, Josh Kemppainen, Tristan Muzzy, Travis Wavrunek, Gregory Odegard

Michigan Tech Publications

Molecular dynamics (MD) simulations have become a powerful tool for studying polymers, designing new materials, and composites. Mechanical behavior in MD simulations are typically evaluated through stress-strain curves. However, MD-generated stress-strain curves are often obscured by thermal noise from atomic vibrations. This noise complicates the reliable derivation of mechanical properties and hinders objective and reproducible analysis. The noise in the stress-strain curves has been removed by using a Butterworth low-pass filter, enabling clearer interpretation of stress-strain data. Building on this, a novel analysis framework the Regression Fringe Response (RFR) is introduced to systematically determine the Young's modulus, yield strength, and …

Thou Shall Not Compel Speech: Public Educators’ Free Speech Rights In The Face Of Louisiana’S “Ten Commandments” Law And Other Rules Compelling Private Expression From Public School Teachers, Kailey A. Olsson

San Diego Law Review

First Amendment jurisprudence has significantly evolved within the past decade as the Supreme Court has expanded religious protections, further developed the Compelled-Speech Doctrine, and narrowed what public school activities are considered violations of the Establishment Clause.  There is no other U.S. Supreme Court case that illustrates these monumental shifts in First Amendment interpretation quite like Kennedy v. Bremerton School District.  Writing for the majority, Justice Gorsuch found that a public school district could not suppress the personal religious expression of a football coach, even when that coach led a prayer activity with other football players and within view of other …

Regulating Retirement Savings Roulette: A Framework For Evaluating Prudence Of Cryptocurrency Investments In 401(K)S, Lauren K. Valastro

San Diego Law Review

Foolhardy or farsighted, Americans are investing their retirement savings in volatile cryptocurrencies.  These investments, conducted largely through brokerage windows enabling plan participants to invest in options not on their employer-sponsored retirement plan menu, are increasing.  Clarity on whether and to what extent fiduciary duties apply to self-directed brokerage windows in 401(k)s is needed to protect Americans’ retirement outlooks and to equip fiduciaries with enough information to fulfil their obligations.  No agency or court has confirmed the existence of fiduciary duties relating to brokerage windows, let alone defined the contours of any such duty.  The Department of Labor (DOL) recently withdrew …
