Origami Folding Pattern Development For Gossamer 18 Structures, Larry L. Howell, Ivy Running, Carolina Wright, Robert J. Lang, Spencer Magleby

Faculty Publications

Gossamer structures for satellites are large, thin deployable structures that are attractive for space applications because they can be stowed compactly for transportation and deployed to have large functional surface areas. Reflectarray antennas, in particular, are candidates for gossamer structures because they can be realized on thin membranes. However, the efficiency of reflectarray antennas decreases with any deviations from a flat plane, including those induced by plastically deformed creases. Rolling membranes can prevent some plastic deformation, but requires relative slipping between layers that are rolled together. In this work, we describe, analyze, and demonstrate two rolled configurations for deployable gossamer …

Sealed Justice: Federal Courts' Inconsistent Record-Sealing Rules And Their Impact On Judicial Transparency, David S. Ardia

Faculty Publications

Public access to court records is a cornerstone of democratic governance, enabling public oversight of the judiciary and fostering confidence in the rule of law. Despite a strong presumption in favor of openness under both the First Amendment and common law, the sealing of federal court records has become widespread, often with minimal judicial scrutiny. Re-cent investigations have revealed that excessive court secrecy shields government and corporate misconduct, conceals vital public-safety information, and erodes public confidence in the courts.

This Article presents the first comprehensive analysis of the local rules governing sealing in all 94 federal districts, reviewing more than …

Scrutinizing Transgender Healthcare Bans Through Intersex Exceptions, Holning Lau, Barbara A. Fedders

Faculty Publications

Major professional medical organizations—for example, the American Academy of Pediatrics, American Medical Association, and Endocrine Society—consider gender-affirming care to be safe and, at times, essential for vulnerable transgender youth. Despite these benefits, 26 states have banned gender-affirming care for minors. Proponents of these bans raise concerns about potential medical harms, the irreversibility of treatments, and the adequacy of informed consent.

Every state ban includes an exception for so-called gender-normalizing surgeries, which are performed on intersex infants to conform their bodies to socially constructed expectations about the male/female binary. The procedures are rarely medically necessary, but proponents of the surgeries contend …

Notice, Consent, And Choice-Of-Jurisdiction Clauses In The United States, John F. Coyle

Faculty Publications

Although choice-of-jurisdiction clauses are routinely enforced by courts in the United States, there are circumstances where they are subject to special scrutiny. One of these circumstances is when the party resisting the clause was not provided with proper notice as to the existence of the clause or the identity of the chosen jurisdiction. This Article first reviews the existing case law in this area and shows that while some U.S. courts have refused to enforce clauses for lack of notice, others do so as a matter of course. It then discusses several decisions where U.S. courts have held that notice …

Death And Debts, Kevin Bennardo

Faculty Publications

This Article analyzes how inheritance law treats debts owed to and by a decedent, focusing on the Uniform Probate Code’s treatment of unpaid purchase-price balances associated with specifically devised property. While UPC §2‑606(a)(1) automatically gives the outstanding balance to the specific devisee, the Article argues that this rule is inconsistent with modern intent‑based ademption doctrine and with the Code’s treatment of debts owed by the estate. It contends that only outstanding balances secured by the devised asset reflect a meaningful connection to the testator’s likely intent. Unsecured balances, by contrast, should not automatically avoid ademption. The Article proposes amending the …

Tax Compliance, Social Norms, And Influencers, James Alm, Jay A. Soled, Kathleen Delaney Thomas

Faculty Publications

While attaining perfect tax compliance is unachievable, more can and must be done. In the past, the country has relied primarily on a traditional system of sticks (e.g., audits and penalties) and carrots (e.g., refunds and whistleblower awards) to help narrow the “tax gap,” or the difference between what taxpayers owe in taxes and what they actually pay. Now, in the social media era, Congress and the Internal Revenue Service (IRS) should look beyond these traditional enforcement mechanisms. To achieve an even higher voluntary compliance rate, this Article advocates for policymakers to invest greater resources to enhance the social norm …

Dividing Trademark Use, Jeremy N. Sheff

Faculty Publications

The trademark law of the United States places special emphasis on whether and how a trademark is used in commerce. But over the long history of the Lanham Act—including some less-than-careful drafting by Congress and some aggressive acts of interpretation by the federal courts—the concept of “use” has become complicated and in many ways confused. Two recent Supreme Court cases—Jack Daniel’s Properties, Inc. v. VIP Products LLC and Abitron Austria GmbH v. Hetronic International, Inc.—reflect and in some ways exacerbate that confusion. But the opinions in these cases also expose an interesting property of “use” in trademark law …

Getting The Reader To Say “Yes”: Applying Negotiation Principles From The Books Getting To Yes And Getting Past No To Achieve Effective And Persuasive Legal Writing, Patricia G. Montana

Faculty Publications

This Article explores the relationship between the strategies of principled negotiation and effective persuasive legal writing as articulated in the best-selling books, Getting to Yes and Getting Past No. Though there is substantial scholarship advocating adding a negotiation component to legal writing instruction, there is little scholarship addressing how to apply the concepts of principled negotiation to persuasive writing itself. In this Article, the Author explains the foundational concepts of principled negotiation and then shows how they relate and apply to drafting an effective piece of persuasive legal writing. Looking at written advocacy through a negotiation lens reinforces good …

Ban Cookie Banners: A Case Study In Tech Regulation, Kate Klonick

Faculty Publications

Few experiences on the modern internet are as universally reviled as the cookie banner. They clutter websites with pop-ups, interrupt user flow, make information harder to access, and demand repetitive, meaningless clicks. What was once heralded as a tool to advance individual autonomy and privacy has, in practice, become a daily annoyance that breeds cynicism with the very concept of consent itself. Cookie banners do not empower; they weary. They do not inform; they obscure. They do not prevent surveillance; they normalize it.

The tragedy of the cookie banner is that it embodies the best intentions but worst solutionism of …

The Whiteness Of Wealth & Black Student Loan Debt, Renee Nicole Allen

Faculty Publications

On June 30, 2023, to the dismay of many anxious borrowers, the Supreme Court held that the Secretary of Education did not have the authority to cancel roughly $430 billion in federal student loan balances, thus blocking President Biden’s plan for student loan forgiveness. Despite authority delegated to the Secretary to waive or modify provisions of the Education Act to ensure low-to-middle income borrowers were not placed in a worse financial position because of the COVID-19 national emergency, the Court rejected the forgiveness plan and borrowers resumed payments in October 2023. Anti-Black racism in federal law and policy have contributed …

Existential Responsibility In Kierkegaard, Nietzsche, And Chiang, Justin F. White

Faculty Publications

In “Story of Your Life” and “Anxiety Is the Dizziness of Freedom,” Ted Chiang explores questions that would be at home in contemporary scholarship on free will, agency, and moral responsibility. In “Story of Your Life,” Chiang asks whether knowledge of the future is compatible with free will. And the prism technology in “Anxiety Is the Dizziness of Freedom” prompts questions of whether we are responsible for out-of-character actions. If such actions were genuine anomalies, would we be less responsible for them? In these stories, however, these questions are entangled with questions more at home in the existentialist tradition. Put …

Evaluation Of Impact Energy In Composites Using Acoustic Emission Sensing Technique, Li Ai, Tanner Mesaric, Sydney Flowers, Sydney Houck, Joshua Widawsky, Paul Ziehl

Faculty Publications

A major challenge faced by composite materials is impact, which can result in unexpected damage and degradation. Impact events can cause significant structural damage that may not be immediately visible, leading to a reduction in the material’s mechanical properties and overall performance. This paper presents an impact assessment method using acoustic emission (AE) sensing technology. The primary goal of this approach is to determine the extent of impact damage on composite components by analyzing AE signals produced under operating stress conditions. An advanced algorithm is proposed to predict the probability that the damage falls into various damage categories, providing a …

Dynamic Analysis Of Additively Manufactured Tensegrity Structures, Keivan Davami, Russell A. Rowe, Ben Gulledge, Jesse Park, Ali Beheshti, Anthony N. Palazotto, Fariborz Tavangarian, Sadie Beck

Faculty Publications

Herein, we present an analysis, design, and experimental testing of modular prestressed pin-jointed structures constructed from bistable units and inspired by the classical triangular tensegrity prism. Tensegrity structures, characterized by a combination of tension members (cables) and compression members (bars) in a self-equilibrated state, have gained significant attention in engineering over the past two decades due to their unique nonlinear mechanical behavior. The discontinuity of the compression members in tensegrity structures leads to a slightly different failure behavior compared to their lattice structure counterparts, with unprecedented applications. However, traditional fabrication and assembly methods have posed challenges for their widespread adoption. …

Phase Transitions In The Co-Doped Heusler Alloy Ni2mn1−Xcoxga, Jing Han Chen, Tej Poudel Chhetri, Nathaniel Wrobel, Xiaojian Bai, David P. Young, Igor Dubenko, Saikat Talapatra, Naushad Ali, Shane Stadler

Faculty Publications

The phase transitions of a series of Co-doped Heusler alloys, Ni 2 Mn 1 − x Co x Ga ( 0 ⩽ x ⩽ 0.2 ), were investigated experimentally using the magnetization measurements, x-ray diffraction, and calorimetric measurements up to their respective melting points. With increasing Co concentration, the structural transition temperatures, Curie temperatures, and melting points, were observed to increase, while the order-disorder transition temperatures decreased. Temperature-dependent x-ray diffraction experiments revealed two different crystal structures in the low-temperature martensite phase for different Co concentrations. However, above their respective structural transitions, both low-temperature crystal structures transformed into the L2 1 …

Capacity-Weighted Figures-Of-Merit For Battery Transport Metrics, Cj Sturgill, Christopher Sutton, Julian Schwenzel, Morgan Stefik

Faculty Publications

New battery materials with improved transport are needed. Typical measurements yield widely varying voltage-dependent diffusivities and reporting practices are diverse. Some materials (e.g. first-order phase change) have most redox occur at a specific voltage and may be sufficiently represented by singular transport metrics. Many rapid intercalation materials, however, exhibit second-order phase transitions with redox over a broad voltage range. How should such cases be compared? The use of capacity-weighted average values is suggested where voltage-dependent metrics are consolidated into representative descriptors as figures-of-merit. Examples are elaborated where differential capacity (dQ/dV) is used to derive a …

The Boris Experience: Evaluating Omnichannel Returns And Repurchase Intention, Jianliang Hao, Robert G. Richey Jr., Tyler R. Morgan, Ian M. Slazinik

Faculty Publications

Researchers have examined the influence of the factors on reducing return rates in retailing over the years. However, the returns experience is often an overlooked way to drive customer engagement and repeat sales in the now ubiquitous omnichannel setting. The focus on returns prevention in existing research overshadows management’s need to understand better the comprehensive mechanics linking the customer in-store return experience with their repurchase actions. Recognizing the need to bridge different stages of the returns management process, this research aims to explore the facilitators and barriers of in-store return activities.

Manolo Santana: El Sonriente Héroe Quijotesco Que Convirtió El Tenis En Un Deporte De Masa En España, Juan Carlos Castillo Berástegui

Faculty Publications

El concepto del héroe quijotesco ha sido propuesto como modelo a seguir como parte de los esfuerzos nacionalizadores del régimen de Francisco Franco (1939-75). A diferencia de los símbolos formales de la nación española, como la bandera y el himno, que nunca se desasociaron políticamente por completo de la dictadura, el retrato como héroes nacionales de ciertos deportistas en disciplinas individuales los convirtió en exitosos símbolos informales de la nación española y su supuesto carácter nacional. El tenista Manolo Santana, cuya carrera cubrió principalmente la década de los 60, fue uno de los héroes quijotescos originales del deporte español, cuya …

Controlled intracellular delivery of biomolecular cargo is critical for developing targeted therapeutics and cell reprogramming. Conventional delivery approaches (e.g., endocytosis of nano-vectors, microinjection, and electroporation) usually require time-consuming uptake processes, labor-intensive operations, and/or costly specialized equipment. Here, we present an acoustofluidics-based intracellular delivery approach capable of effectively delivering various functional nanomaterials to multiple cell types (e.g., adherent and suspension cancer cells). By tuning the standing acoustic waves in a glass capillary, our approach can push cells in flow to the capillary wall and enhance membrane permeability by increasing membrane stress to deform cells via acoustic radiation forces. Moreover, by coating …
