Degradation Mechanism Detection In Photovoltaic Backsheets By Fully Convolutional Neural Network, Laura S. Bruckman

Faculty Scholarship

Materials and devices age with time. Material aging and degradation has important implications for lifetime performance of materials and systems. While consensus exists that materials should be studied and designed for degradation, materials inspection during operation is typically performed manually by technicians. The manual inspection makes studies prone to errors and uncertainties due to human subjectivity. In this work, we focus on automating the process of degradation mechanism detection through the use of a fully convolutional deep neural network architecture (F-CNN). We demonstrate that F-CNN architecture allows for automated inspection of cracks in polymer backsheets from photovoltaic (PV) modules. The …

The Other Janus And The Future Of Labor’S Capital, David H. Webber

Faculty Scholarship

Two forms of labor’s capital—union funds and public pension funds—have profoundly reshaped the corporate world. They have successfully advocated for shareholder empowerment initiatives like proxy access, declassified boards, majority voting, say on pay, private fund registration, and the CEO-to-worker pay ratio. They have also served as lead plaintiffs in forty percent of federal securities fraud and Delaware deal class actions. Today, much-discussed reforms like revised shareholder proposal rules and mandatory arbitration threaten two of the main channels by which these shareholders have exercised power. But labor’s capital faces its greatest, even existential, threats from outside corporate law. This Essay addresses …

The Legal Design For Parenting Concussion Risk, Katharine B. Silbaugh

Faculty Scholarship

This Article addresses a question as yet unexplored in the emerging concussion risk literature: how does the statutorily assigned parental role in concussion risk management conceptualize the legal significance of the parent, and does it align with other areas of law that authorize and limit parental risk decision-making? Parents are the centerpiece of the “Lystedt” youth concussion legislation in all fifty states, and yet the extensive legal literature about that legislation contains no discussion of parents as legal actors and makes no effort to situate their statutory role into the larger legal framework of parental authority. This Article considers the …

Regarding Docket No. Fr-6111-P-02, Hud’S Implementation Of The Fair Housing Act’S Disparate Impact Standard, Sonia Gipson Rankin, Alfred Mathewson, Melanie Moses, G. Matthew Fricke, Kathy Powers, Gabriel R. Sanchez, Christopher Moore, Elizabeth Bradley, Mirta Galesic, Joshua Garland

Faculty Scholarship

The is a Comment on the Department of Housing and Urban Development (HUD) Proposed Rule: FR-6111-P-02 HUD’s Implementation of the Fair Housing Act’s Disparate Impact Standard . This comment examines how algorithms in housing applications may be inherently biased against certain groups of people.

Their arguments against the proposed legislation:

1. To ensure that an algorithm does not have disparate impact, it is not enough to show that individual input factors are not “substitutes or close proxies” for protected characteristics.

2. It is impossible to audit an algorithm for bias without an adequate level of transparency or access to the …

Voltage-Gated Potassium Channels Are Critical For Infrared Inhibition Of Action Potentials: An Experimental Study, Junqi Zhuo, Matthew T. Mcpheeters, Michael W. Jenkins, Hillel J. Chiel

Faculty Scholarship

Thermal block of unmyelinated axons may serve as a modality for control, suggesting a means for providing therapies for pain. Computational modeling predicted that potassium channels are necessary for mediating thermal block of propagating compound action potentials (CAPs) with infrared (IR) light. Our study tests that hypothesis. Results suggest that potassium channel blockers disrupt the ability of IR to block propagating CAPs in Aplysia californica nerves, whereas sodium channel blockers appear to have no significant effect. These observations validate the modeling results and suggest potential applications of thermal block to many other unmyelinated axons.

When Protest Is The Disaster: Constitutional Implications Of State And Local Emergency Power, Karen Pita Loor

Faculty Scholarship

The President’s use of emergency authority has recently ignited concern among civil rights groups over national executive emergency power. However, state and local emergency authority can also be dangerous and deserves similar attention. This article demonstrates that, just as we watch over the national executive, we must be wary of and check on state and local executives — and their emergency management law enforcement actors — when they react in crisis mode. This paper exposes and critiques state executives’ use of emergency power and emergency management mechanisms to suppress grassroots political activity and suggests avenues to counter that abuse. I …

The Missing Regulatory State: Monitoring Businesses In An Age Of Surveillance, Rory Van Loo

Faculty Scholarship

An irony of the information age is that the companies responsible for the most extensive surveillance of individuals in history—large platforms such as Amazon, Facebook, and Google—have themselves remained unusually shielded from being monitored by government regulators. But the legal literature on state information acquisition is dominated by the privacy problems of excess collection from individuals, not businesses. There has been little sustained attention to the problem of insufficient information collection from businesses. This Article articulates the administrative state’s normative framework for monitoring businesses and shows how that framework is increasingly in tension with privacy concerns. One emerging complication is …

Disguised Patent Policymaking, Saurabh Vishnubhakat

Faculty Scholarship

Patent Office power has grown immensely in this decade, and the agency is wielding its power in predictably troubling ways. Like other agencies, it injects politics into its decisions while relying on technocratic justifications. It also reads grants of authority expansively to aggrandize its power, especially to the detriment of judicial checks on agency action. However, this story of Patent Office ascendancy differs from that of other agencies in two important respects. One is that the U.S. patent system still remains primarily a means for allocating property rights, not a comprehensive regime of industrial regulation. Thus, the Patent Office cannot …

Access To Law Or Access To Lawyers? Master's Programs In The Public Educational Mission Of Law Schools, Mark Burge

Faculty Scholarship

The general decline in juris doctor (“J.D.”) law school applicants and enrollment over the last decade has coincided with the rise of a new breed of law degree. Whether known as a master of jurisprudence, juris master, master of legal studies, or other names, these graduate degrees all have a target audience in common: adult professionals who neither are nor seek to become practicing attorneys. Inside legal academia and among the practicing bar, these degrees have been accompanied by expressed concerns that they detract from the traditional core public mission of law schools—educating lawyers. This Article argues that non-lawyer master’s …

Liquid Business, Vanessa Casado-Pérez

Faculty Scholarship

Water is scarcer due to climate change and in higher demand due to population growth than ever before. As if these stressors were not concerning enough, corporate investors are participating in water markets in ways that sidestep U.S. water law doctrine’s aims of preventing speculation and assuring that the holders of water rights internalize any externalities associated with changes in their rights. The operation of these new players in the shadow of traditional water law is producing elements of inefficiency and unfairness in the allocation of water rights. Resisting the polar calls for unfettered water markets, or, contrarily, the complete …

Characterization Of Cerium (Iii) Ion Binding To Surface‐Immobilized Ef‐Hand Loop I Of Calmodulin, Mingyuan Xu, Zihang Su, Julie N. Renner

Faculty Scholarship

Cerium has a wide range of current and emerging applications, and the binding of cerium ions to solid substrates is important for cerium recovery, or in advanced material synthesis. In this study, we investigate the affinity of a surface-bound peptide derived from the EF-hand loop I of calmodulin for cerium (III) ions and compare the results to a scrambled control. Results obtained via quartz crystal microbalance with dissipation are used to estimate the dissociation constant between the EF-hand loop I peptide and cerium (III) ions (1.3 ± 0.1 μM), which is comparable with other dissociation constants measured for EF-hand peptides …

Fluorescence Microscopy Of Biophysical Protein Dynamics In Nanoporous Hydrogels, Anuj Saini, Lydia Kisley

Faculty Scholarship

Proteins within nanoporous hydrogels have important biotechnological applications in pharmaceutical purification, tissue engineering, water treatment, biosensors, and medical implants. Yet, oftentimes proteins that are functional in solution lose activity when in contact with soft, nanostructured, condensed phase materials due to perturbations in the folded state, conformation, diffusion, and adsorption dynamics of the protein by the material. Fluorescence microscopy experimentally measures the biophysical dynamics of proteins within hydrogels at the nanoscale and can overcome the limitations of conventional ensemble techniques. An explanation of the benefits of fluorescence is provided, and principles of fluorescence microscope instrumentation and analysis are discussed. Then several …

Charged Nanoparticles Quench The Propulsion Of Active Janus Colloids, Marola W. Issa, Christopher L. Wirth

Faculty Scholarship

Active colloidal particles regularly interact with surfaces in applications ranging from microfluidics to sensing. Recent work has revealed the complex nature of these surface interactions for active particles. Herein, we summarize experiments and simulations that show the impact of charged nanoparticles on the propulsion of an active colloid near a boundary. Adding charged nanoparticles not only decreased the average separation distance of a passive colloid because of depletion attraction as expected but also decreased the apparent propulsion of a Janus colloid to near zero. Complementary agent-based simulations considering the impact of hydrodynamics for active Janus colloids were conducted in the …

Data-Driven I–V Feature Extraction For Photovoltaic Modules, Xuan Ma, Wei-Heng Huang, Jenny Brynjarsdottir, Jennifer L. Braid, Roger H. French

Faculty Scholarship

In research on photovoltaic (PV) device degradation, current-voltage (I-V ) datasets carry a large amount of information in addition to the maximum power point. Performance parameters such as short-circuit current, open-circuit voltage, shunt resistance, series resistance, and fill factor are essential for diagnosing the performance and degradation of solar cells and modules. To enable the scaling of I-V studies to millions of I-V curves, we have developed a data-driven method to extract I-V curve parameters and distributed this method as an open-source package in R. In contrast with the traditional practice of fitting the diode equation to I-V curves individually, …

Stability Of Supersonic Flow With Injection, Bryan E. Schmidt

Faculty Scholarship

Gas injection into supersonic flow past a 5-degree half-angle cone is studied with three injected gases: helium, nitrogen, and RC318. Experiments are performed in a Mach 4 Ludwieg tube with nitrogen as the free stream gas. The injector section is shaped to admit a "tuned" injection rate where the displacement created by injection counteracts the effects created by the injector geometry. A high-speed schlieren imaging system with a framing rate of 290 kHz is used to study the instability in the region of flow downstream of injection, referred to as the injection layer. Measurements of wavelength, convective speed, and frequency …

Designing Development Programs For Non-Traditional Antibacterial Agents, John H. Rex, Holly Fernandez Lynch, I. Glen Cohen, Jonathan J. Darrow, Kevin Outterson

Faculty Scholarship

In the face of rising rates of antibacterial resistance, many responses are being pursued in parallel, including ‘non-traditional’ antibacterial agents (agents that are not small-molecule drugs and/or do not act by directly targeting bacterial components necessary for bacterial growth). In this Perspective, we argue that the distinction between traditional and nontraditional agents has only limited relevance for regulatory purposes. Rather, most agents in both categories can and should be developed using standard measures of clinical efficacy demonstrated with non-inferiority or superiority trial designs according to existing regulatory frameworks. There may, however, be products with non-traditional goals focused on population-level benefits …

Wearable Sensors For Monitoring The Internal And External Workload Of The Athlete, Dhruv R. Seshadri, James R. Rowbottom, Celeste Marie Alfes, Christian A. Zorman, Colin K. Drummond

Faculty Scholarship

The convergence of semiconductor technology, physiology, and predictive health analytics from wearable devices has advanced its clinical and translational utility for sports. The detection and subsequent application of metrics pertinent to and indicative of the physical performance, physiological status, biochemical composition, and mental alertness of the athlete has been shown to reduce the risk of injuries and improve performance and has enabled the development of athlete-centered protocols and treatment plans by team physicians and trainers. Our discussions in this review include commercially available devices, as well as those described in scientific literature to provide an understanding of wearable sensors for …

A Tale Of Two Copyrights, Glynn Lunney

Faculty Scholarship

This essay explores two possible copyright regimes. The first uses costless and perfect price discrimination to enable copyright owners to capture the full market or exchange value of their work. The second also uses costless and perfect price discrimination, but allows copyright owners to capture only the persuasion cost for authoring and distributing a work. We can call the first regime, costless copyright maximalism, and the second, costless copyright minimalism. The choice between these two regimes is primarily distributional: Should we design copyright to allocate the surplus associated with copyrighted works to copyright owners or to copyright consumers? This essay …

Wearable Sensors For Monitoring The Physiological And Biochemical Profile Of The Athlete, Dhruv R. Seshadri, James R. Rowbottom, Celeste Marie Alfes, Christian A. Zorman, Colin K. Drummond

Faculty Scholarship

Athletes are continually seeking new technologies and therapies to gain a competitive edge to maximize their health and performance. Athletes have gravitated toward the use of wearable sensors to monitor their training and recovery. Wearable technologies currently utilized by sports teams monitor both the internal and external workload of athletes. However, there remains an unmet medical need by the sports community to gain further insight into the internal workload of the athlete to tailor recovery protocols to each athlete. The ability to monitor biomarkers from saliva or sweat in a noninvasive and continuous manner remain the next technological gap for …

Elite Patent Law, Paul Gugliuzza

Faculty Scholarship

Over the last twenty years, one of the most significant developments in intellectual property law has been the dramatic increase in the number of patent cases decided by the U.S. Supreme Court. That same time period has also seen the emergence of a small, elite group of lawyers specializing not in any particular area of substantive law but in litigation before the Supreme Court. In recent empirical work, I linked the Court’s growing interest in patent law to the more frequent participation of elite Supreme Court lawyers in patent cases, particularly at the cert. stage. Among other things, I found …

Sane Gun Policy From Texas? A Blueprint For Balanced State Campus Carry Laws, Aric Short

Faculty Scholarship

merican universities are caught in the crosshairs of one of the most polarizing and contentious gun policy debates: whether to allow concealed carry on campus. Ten states have implemented "campus carry" in some form; sixteen new states considered passage last year; and a growing wave of momentum is building in favor of additional adoptions. Despite this push towards campus carry, most states adopting the policy fail to strike an effective balance between the competing rights and interests involved. When states give universities the option to opt out of the law, for example, they almost always do. Other states impose a …

Renewed Efficiency In Administrative Patent Revocation, Saurabh Vishnubhakat

Faculty Scholarship

Administrative patent revocation in the U.S. is poised to enter a new period of efficiency, though ironically it will be an efficiency that the America Invents Act originally put in place. The Court’s recent approval of the constitutionality of Patent Trial and Appeal Board ("PTAB") proceedings was blunted by the Court’s accompanying rejection of partial institution. This Patent Office practice of accepting and denying validity review petitions piecemeal had been a key part of the agency’s procedural structure from the start. As a result, the Court’s decision in SAS Institute v. Iancu to require a binary choice — either fully …

Interactions Of Polyproline Ii Helix Peptides With Iron(Iii) Oxide, Charles N. Loney, Cheyan Xu, Ashley Graybill, Julie N. Renner

Faculty Scholarship

Interactions of a peptide with polyproline II helical secondary structure with maghemite (iron(III) oxide, Fe2O3) surfaces were characterized using a variety of surface techniques. A quartz crystal microbalance with dissipation was used to measure the hydrated mass and thickness (92 ± 29 ng/cm2 and 0.89 ± 0.27 nm, respectively) of a layer which formed after a sensor coated with Fe2O3 was exposed to the peptide in aqueous solution. The analysis revealed that the peptide formed a stable thin layer on the sensor. X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy of the monolayer were employed to study the relationship between the …

Bakke’S Lasting Legacy: Redefining The Landscape Of Equality And Liberty In Civil Rights Law, Rachel F. Moran

Faculty Scholarship

The fortieth anniversary of Regents of the University of California v. Bakke is worth commemorating simply because the decision has survived. The United States Supreme Court’s opinion upholding the use of race in admissions has had remarkable staying power, even as other programs of affirmative action, for example, in government contracting, have been struck down as unconstitutional. That longevity might seem surprising because Bakke set forth an exacting standard of strict scrutiny under equal protection law that renders all race-based classifications suspect, whether government officials are motivated by benign or invidious purposes. That standard is one that few programs can …
