Overqualified And Underrepresented: Gender Inequality In Pharmaceutical Patent Law, S. Sean Tu, Paul R. Gugliuzza, Amy Semet Dec 2022

Overqualified And Underrepresented: Gender Inequality In Pharmaceutical Patent Law, S. Sean Tu, Paul R. Gugliuzza, Amy Semet

Journal Articles

Pharmaceutical patents represent some of the most valuable intellectual property assets in the world: they can be worth billions of dollars if courts uphold their validity and find them infringed. But, if invalidated, generic drug manufacturers can get to market earlier, generating billions of dollars of revenue for themselves and creating enormous savings for consumers. Accordingly, drug patents are the product of careful, high-cost prosecution and are associated with high-stakes, bet-the-company litigation. But women lawyers are noticeably absent from pharmaceutical patent practice. This article reports an original empirical study finding that women comprise only one-third of the top pharmaceutical patent …

Research On Iterative Calculation And Optimization Methods Of Aero-Engine On-Board Model, Xinghua Luo, Jia Geng, Ming Li, Bei Liu, Lei Wang, Zhiping Song

Journal of System Simulation

Abstract: Aeroengine is a complex and time-varying multivariable thermophysical system. The research on the convergence accuracy and rate of the component-level model is of great significance to the model-based engine health management, performance and fault-tolerant control. The existing engine component-level models are generally based on the traditional quasi-Newton method to solve the equilibrium equations simultaneously. Compared with the traditional Newton-Raphson method (N-R method), the convergence speed is optimized, but it is difficult to meet accuracy and real-time requirements of the dynamic model airborne applications within the full envelope. An adaptive variable step factor quasi-Newton method is proposed, which can reduce …

Physical Model Of Cilia Motion, Toby Utterback Dec 2022

Physical Model Of Cilia Motion, Toby Utterback

Mechanical Engineering and Materials Science Independent Study

The motion of cilia could be further understood by creating and analysing a large scale model with similar stiffness and property values. Varying amounts of vibrating HEXBUG robots, representing motion and active particles, were placed in series with different segment lengths connecting them. The oscillating motion of a ciliium was able to be replicated and analyzed using autotracing and autotracking programs. The amplitude of the model increased with increasing length, while increasing length had an inconclusive effect on period. Furthermore, the visual path of a marked end segment repeated with each oscillation recorded.

Effect Of Diabetes-Associated Mutations In Kir 6.2/Sur1 On Katp Channel Activities, Yunpeng Li

McKelvey School of Engineering Graduate Student Theses & Dissertations

Maturity Onset Diabetes of the Young (MODY) is a type of diabetes, distinct from either type I or type II, that happens before age 25 (MedlinePlus, 2022). Unlike the other two more common forms of diabetes, MODY is classified as a series of monogenetic disorders (American Diabetes Association Professional Practice Committee, 2021), caused by autosomal mutations. MODY is typically characterized by insufficient secretion of insulin, a similar symptom to type I diabetes, classified into 14 different types based on mutations found on different genes. Among them, subtypes 12 and 13, also called neonatal diabetes mellitus (NDM), are caused by gain-of-function …

Research On Low Computational Predictive Control Strategy Of Three-Level Four-Arm Apf, Guifeng Wang, Jinxing Guo Dec 2022

Research On Low Computational Predictive Control Strategy Of Three-Level Four-Arm Apf, Guifeng Wang, Jinxing Guo

Journal of System Simulation

Abstract: Four-arm active power filter(APF) is an ideal device to the power quality of three-phase four-wire distribution network. Owing to the sufficient number of base vectors, three-level four-arm APF has better current tracking performance, but the prediction calculation amount is too large when model predictive current control is applied. A model prediction voltage control strategy based on the idea of space stratification is proposed. Based on the deadbeat control idea and the discrete mathematical model in αβγ coordinate system, the expected reference voltage is predicted from the reference current, and the multiple current predictions are converted into the single voltage …

Gatekeeping Admissions: Access To Justice And Inclusive Admissions Processes, Sarah Kriekle Dec 2022

Gatekeeping Admissions: Access To Justice And Inclusive Admissions Processes, Sarah Kriekle

Dalhousie Journal of Legal Studies

Law schools are the gatekeepers to the legal profession, and there are multiple social barriers that impact access to a legal education across a proportionally diverse range of people. This article will first rely on existing literature to demonstrate why diversity in the legal profession is an access to justice issue and to illustrate the current homogeneity that exists within the profession. This article will then argue that two primary factors prevent law schools from attracting a more diverse student body. The first factor is the over-reliance on numerical statistics like grade point average (GPA) and Law School Admissions Test …
