Pediatric Body Mass Index (Bmi) And Distal Radius Fracture Incidence, Jessica Avila, Tyler Hough, Nikalus Skipp, Amber L. West, Deana Mercer

Western Journal of Orthopaedics

Background: The authors postulate that obesity in children increases the risk of distal radius fracture compared to children who are not obese. Because it is difficult to determine the population at risk, the authors observed the inverse of the rate of obesity in pediatric patients with distal radius fractures in an attempt to determine if there was a difference compared to national data on frequency of obesity in the pediatric population in general. If the rate of obesity was greater in distal radius fractures than the overall population, this would constitute evidence that obesity may increase the risk of distal …

Design Of Multi-Objective Optimization Algorithms For Vlsi Floor Planning, Srinivasan B

Theses and Dissertations

VLSI floorplanning is a key design step that determines the optimal placement of circuit modules to minimize chip area, wire length, and heat generation. Existing swarm intelligence–based metaheuristics improve area and wire length but often ignore thermal effects.

To address this, the Multi-Objective Firefly Optimization–based Floorplanning (MOFO-FP) technique is introduced, using a Heat-Aware Firefly Optimization (HAFO) algorithm that minimizes heat, space, and wire length under fixed outline constraints. Each firefly represents a floorplan, with brightness indicating solution quality; dimmer fireflies move toward brighter ones to find optimal placements.

S.B. 98 And The Outer Limits Of Journalism, Daniel Lemer

Loyola of Los Angeles Law Review

Senate Bill 98 (S.B. 98), signed into law on October 9, 2021, aims to safeguard the right of journalists in California to cover public protests without police interference. However, the bill is silent as to who qualifies as a journalist and thus falls under its protections. This Note analyzes different approaches to defining the press in the legal, academic, and journalistic fields. In the context of S.B. 98, it advocates for a broad, process-based definition that encompasses a wide range of newsgatherers, from established professionals writing for major publications, to individuals documenting the events unfolding in their communities with nothing …

Who’S Afraid Of Diversity, Equity, And Inclusion Statements In Faculty Hiring And Promotion At California Universities?, Matthew W. Babb

Loyola of Los Angeles Law Review

In 1996, California banned affirmative action in both state employment and state education. This ban extends to California’s universities, which are therefore prohibited from using race, sex, color, ethnicity, or national origin in faculty hiring and promotion as well as student admissions. As a result, California’s universities have had to think of alternative ways to improve the diversity of their faculty and students. One solution many California universities have adopted is to ask applicants for faculty positions or promotions to submit a statement describing their approach to diversity, equity, and inclusion. However, the use of diversity, equity, and inclusion statements …

Why We Should Stop Talking About Violent Offenders: Storytelling And Decarceration, Mira Edmonds

Articles

The movement to decarcerate risks foundering because of its failure to grapple with so-called violent offenders, who make up nearly half of U.S. prisoners. The treatment of people serving sentences for offenses categorized as violent is a primary reason for the continued problem of mass incarceration, despite widespread awareness of the phenomenon and significant bipartisan interest in its reduction. People convicted of “violent offenses” are serving historically anomalous and excessively long sentences, are generally denied clemency and compassionate release, and are excluded from a wide array of legal reform and policy changes with decarceral aims. Keeping these people in prison …

Morgan V. Sundance: A Legal Overview Of The Prejudice Requirement In Arbitration And Its Impact On Litigation, Sergio Fernandez

University of Dayton Law Review

Since the enactment of the Federal Arbitration Act (“FAA”) in 1925, arbitration clauses have been embedded in the commercial contractual ambit and have been a predominant tool employed not only in transactions between corporations, but most importantly between corporations and individuals. Arbitration is a tool used in both the public and private sector to resolve disputes without channeling the usual litigation route. Arbitration, like other forms of alternative dispute resolution (“ADR”), has attributes beneficial to the disputing parties. It “reduces the judiciary’s workload and reduces litigation costs, allowing companies to offer lower prices and higher wages.” It is known to …

Study Of Graphene P-N Junctions Formed By The Electrostatic Modification Of The Sio Substrate, Tharanga R. Nanayakkara, U Kushan Wijewardena, Annika Kriisa, Ramesh G. Mani

Faculty and Staff Works

We study the transport properties of mm-scale CVD graphene p-n junctions, which are formed in a single gated graphene field effect transistor configuration. Here, an electrical-stressing-voltage technique served to modify the electrostatic potential in the SiO/Si substrate and create the p-n junction. We examine the transport characteristics about the Dirac points that are localized in the perturbed and unperturbed regions in the graphene channel and note the quantitative differences in the Hall effect between the perturbed and unperturbed regions. The results also show that the longitudinal resistance is highly sensitive to the external magnetic field when the Hall bar device …
