Evaluation Of Objective Methods For Analyzing Ipsilateral Motor Evoked Potentials In Stroke Survivors With Chronic Upper Extremity Motor Impairment, Xin Li, Jayme S. Knutson, Xiaofeng Wang, Ken Uchino, Ela B. Plow, David A. Cunningham

Faculty Scholarship

Objective. Ipsilateral motor evoked potentials (iMEPs) are believed to represent cortically evoked excitability of uncrossed brainstem-mediated pathways. In the event of extensive injury to (crossed) corticospinal pathways, which can occur following a stroke, uncrossed ipsilateral pathways may serve as an alternate resource to support the recovery of the paretic limb. However, iMEPs, even in neurally intact people, can be small, infrequent, and noisy, so discerning them in stroke survivors is very challenging. This study aimed to investigate the inter-rater reliability of iMEP features (presence/absence, amplitude, area, onset, and offset) to evaluate the reliability of existing methods for objectively analyzing iMEPs …

The Interchangeable-Part Structure Of Food And Drug Law, Adam I. Muchmore Apr 2025

The Interchangeable-Part Structure Of Food And Drug Law, Adam I. Muchmore

Faculty Scholarship

This Article demonstrates that nested tiers of interchangeable parts serve as the foundation for the regulatory programs administered by the U.S. Food and Drug Administration. Core interchangeable parts used in FDA-administered programs include product categories, prohibitions on adulteration and misbranding, agency-registration requirements, current good manufacturing practices, product standards, marketing authorization requirements, postmarket requirements, and user fees. In each of these areas, Congress or the FDA has engaged in interchangeable-part lawmaking (IPL). IPL occurs when a government takes a portion of its law in one subject area and uses it as a model for its own law in another subject area. …


Dictating The Divine: Revisiting Authorship, Intention, And Authority From Sacred Texts To Generative Ai, James Hutson, W. Travis Mcmaken Apr 2025

Dictating The Divine: Revisiting Authorship, Intention, And Authority From Sacred Texts To Generative Ai, James Hutson, W. Travis Mcmaken

Faculty Scholarship

This article interrogates the historical practice of mediated authorship in religious texts to draw critical parallels with contemporary debates surrounding generative artificial intelligence (AI), specifically large language models (LLMs). By juxtaposing the mediated authorship of sacred texts, such as the Hebrew Bible and New Testament—where figures like the Apostle Paul dictated theological concepts to scribes who infused these directives with their interpretive insights—with the generative processes of LLMs, this research underscores the shared dynamics of co-constructed authorship across historical and technological contexts. Employing interdisciplinary methodologies from art history, textual studies, and reception theory, as well as theological and biblical studies, …

Living Nondirected Kidney Donation: A Psychoanalytic Case-Based Investigation Of Altruism And Its Implications For Psychosocial Evaluation Guidelines, Robert M. Guerin

Faculty Scholarship

Why donate a kidney to a stranger? The history of living nondirected kidney donation, so-called altruistic or Good Samaritan donation, is notable for its associated skepticism if not outright rejection. Since its possibility, transplantation institutes have been concerned over the motives of individuals who present to their clinics with the wish to donate a kidney to a stranger. Are these motives pure? Might there be ulterior motives or secondary gain? Or might these motives be pathological, derivative from a psychiatric disease or syndrome? Although attitudes toward the nondirected donor have improved, skepticism remains: Why, after all, benefit another in this …

Experimental Investigation Of External Flow Condensation Heat Transfer In Horizontal Tube-In-Tube Configuration, Jiayuan Li, Jayachandran K. Narayanan, Chirag R. Kharangate

Faculty Scholarship

Flow condensation is an important process used to achieve heat rejection across thermal power and energy systems. Studies on tube condensation have concentrated on the condensing fluid flowing in the inner tube. However, common heat exchanger configurations like the shell-and-tube types see the condensing fluid on the outer surface of the tubes. To address this gap, in this study, we investigate the local and channel-averaged heat transfer characteristics of flow condensation happening on the exterior of a horizontal tube in the tube-in-tube configuration. An external flow condensation module is developed and tested to obtain heat transfer and flow visualization data, …

Alphafold 3, Ai, Antibody Patents, The Future Of Broad Pharmaceutical Patent Claims, And Drug Development, Brendan Bargmann, Robert A. Bohrer

Faculty Scholarship

Artificial intelligence (AI) will have an enormous impact both on pharmaceutical development and patent protection, particularly for antibody therapeutics. In Amgen Inc. v. Sanofi, the U.S. Supreme Court limited the scope of Amgen’s therapeutic antibody patent to only those antibodies that were specifically described in Amgen’s patent application and that had been shown to bind to a particular region of the target antigen, blocking the activity of the antigen that caused disease. The reason for this limitation was the patent requirement of enablement: that potentially millions of antibodies could be generated to the target antigen but that not all …

Emerging water pollutants are a growing global concern due to their ubiquitous presence in water resources worldwide and their potential adverse effects on human health and ecosystems. Limited scientific understanding of sources of emerging pollutants’ emissions to water bodies and their pathways, behaviour, and fate in aquatic environments, as well as human health and ecological effects, is a significant hindrance in managing emerging water pollutants. With exceptions concerning PFAS/PFOS and microplastic beads, there are few regulations for emerging pollutants in national water and environmental policies, which results in a critical gap in safeguarding human health and aquatic ecosystems through effective …


Who Owns The Heat? Property Rights In Geothermal Energy, Gabriel Eckstein Apr 2025

Who Owns The Heat? Property Rights In Geothermal Energy, Gabriel Eckstein

Faculty Scholarship

Landowners can have ownership claims to oil, gas, water, and other tangible natural resources located in their subsoil. But can they also claim rights to the thermal energy found below their land? With 50,000 times more heat energy within the top 10,000 meters (around 33,000 feet) of the Earth’s surface than contained in all of the world’s oil and natural gas resources combined, geothermal energy is a tremendously promising, clean, and renewable energy resource. Yet, ambiguities in property rights related to the development and ownership of geothermal energy resources raise questions about who is entitled to benefit from that potential. …


Micro-Costs, Kiel Brennan-Marquez, Brendan S. Maher Apr 2025

Micro-Costs, Kiel Brennan-Marquez, Brendan S. Maher

Faculty Scholarship

The modern world is filled with tiny attentional impositions (cognitiveasks) that inflict small mental burdens (micro-costs) on virtually everyone, everywhere, all the time. Micro-costs make life worse, and everybody knows it. They sap collective energy; they lead to worse decisions; they exacerbate inequality; and they contribute to an overall sense of "mismanagement" in the world, a sentiment that readily pairs with destructive political impulses.

Yet the law has essentially ignored micro-costs-until now. In what follows, we construct a theory of micro-costs that gives the phenomenon analytic shape and charts a path forward for reform. Drawing on the insights of philosophy, …

Guide To Sec And Business Open Source Corporate Intelligence, Lawrence J. Trautman, Brian Elzweig, Neal F. Newman

Faculty Scholarship

An agency of the U.S. intelligence community observes, "The explosion of open source intelligence (OSINT) in recent years has transformed how governments and people around the world consume and process information about society and global issues." It is likely that "We all use open-source and probably don't even realize it, but we also use it for different reasons. You might use open-source information to do a credibility check and to find out more about the person selling you something on Facebook marketplace." Others "may research someone… met on a dating app or before hiring someone for a job." Every use …

These custom-trained agents leverage human-computer interaction (HCI) technologies and machine learning methodologies to enhance understanding of one’s own learning processes-metacognition-thus empowering individuals to optimize their future learning and adaptability. This approach not only enhances the individual’s ability to engage effectively with complex tasks in the …


Humanist Copyright, Jane C. Ginsburg Apr 2025

Humanist Copyright, Jane C. Ginsburg

Faculty Scholarship

This exploration of the role of authorship in copyright law proceeds in three parts: historical, doctrinal, and predictive. First, I will review the development of author-focused property rights in the pre-copyright regimes of printing privileges and in early Anglo-American copyright law through the 1909 U.S. Copyright Act. Second, I will analyze the extent to which the present U.S. copyright law does (and does not) honor human authorship. Finally, I will consider the potential responses of copyright law to the claims of proprietary rights in AI-generated outputs. I will explain why the humanist orientation of U.S. copyright law validates the position …


Law And Historical Materialism, Jeremy K. Kessler Apr 2025

Law And Historical Materialism, Jeremy K. Kessler

Faculty Scholarship

Since the financial crisis of 2008, left-leaning legal thought has experienced a renaissance within the American academy. From law and political economy to critical race theory to feminist legal studies to Marxist legal theory, new perspectives have flourished, and marginalized traditions have been revived and revised. These new perspectives and revisionist projects all share an intellectual debt to the critical legal studies (“CLS”) movement of the late 1970s and 1980s. That movement’s critique was focused on functional accounts of law: accounts that understood legal change as primarily responsive to the demands of extralegal social and economic forces. Some of those …

Faculty Scholarship

Social robots are a class of emerging smart consumer electronics devices that promise sophisticated experiences featuring emotive capabilities, artificial intelligence, conversational interaction, and more. With unique risk factors like emotional attachment, little is known on how social robots communicate these promises to consumers and whether they adequately deliver upon them within their overall product experiences prior to and during user interaction.

Animated by a consumer protection lens, this paper systematically investigates manufacturer claims made for four commercially available social robots, evaluating these claims against the provided user experience and consumer reviews. We find that social robots vary widely in the …


Memgb-Diff: Memory-Efficient Multivariate Gaussian Bias Diffusion Model For 3d Bias Field Correction, Shuo Li Mar 2025

Memgb-Diff: Memory-Efficient Multivariate Gaussian Bias Diffusion Model For 3d Bias Field Correction, Shuo Li

Faculty Scholarship

Bias fields inevitably degrade MRI that seriously interferes the diagnosis of physicians for accurate analysis, and removing it is a crucial image analysis task. Generative models (such as GANs) are used for bias field correction, and outperform traditional methods, however are hindered by the high cost of data annotation and instability during training. Recently, the diffusion-based methods have excelled over GANs in many applications, and they are powerful in removing noise from images, while the bias field can be regarded as a smooth noise. However, it is a challenge to directly apply to 3D bias field correction due to sampling …


Stable Heteroclinic Channels As A Decision-Making Model: Overcoming Low Signal-To-Noise Ratio With Mutual Inhibition, Natasha A. Rouse Mar 2025

Stable Heteroclinic Channels As A Decision-Making Model: Overcoming Low Signal-To-Noise Ratio With Mutual Inhibition, Natasha A. Rouse

Faculty Scholarship

Bio-inspired robot controllers are becoming more complex as we strive to make them more robust to, and flexible in, noisy, real-world environments. A stable heteroclinic network (SHN) is a dynamical system that produces cyclical state transitions using noisy input. SHN-based robot controllers enable sensory input to be integrated at the phase-space level of the controller, thus simplifying sensor-integrated, robot control methods. In this work, we investigate the mechanism that drives branching state trajectories in SHNs. We liken the branching state trajectories to decision-splits imposed into the system, which opens the door for more sophisticated controls-all driven by sensory input. This …


Soft Robotic Brittle Star Shows The Influence Of Mass Distribution On Underwater Walking, Zach J. Patterson Mar 2025

Soft Robotic Brittle Star Shows The Influence Of Mass Distribution On Underwater Walking, Zach J. Patterson

Faculty Scholarship

Most walking organisms tend to have relatively light limbs and heavy bodies in order to facilitate rapid limb motion. However, the limbs of brittle stars (Class Ophiuroidea) are primarily comprised of dense skeletal elements, with potentially much higher mass and density compared to the body disk. To date, little is understood about how the relatively unique distribution of mass in these animals influences their locomotion. In this work, we use a brittle star inspired soft robot and computational modeling to examine how the distribution of mass and density in brittle stars affects their movement. The soft robot is fully untethered, …

Dietary Effects On The Retina Of Hamsters, Nicole El-Darzi, Natalia Mast, Yong Li, Irina A. Pikuleva Mar 2025

Dietary Effects On The Retina Of Hamsters, Nicole El-Darzi, Natalia Mast, Yong Li, Irina A. Pikuleva

Faculty Scholarship

The retina is a sensory tissue in the back of the eye, which captures visual information and relays it to the brain. The retinal pigment epithelium separates the neural retina from the choroidal (systemic) circulation and is thereby exposed to circulating lipoprotein particles. Herein, we used hamsters and conducted various retinal evaluations of animals fed either a normal diet or a Western-type diet (WTD). Prior to evaluations, hamsters were injected with indocyanine green (ICG), a fluorescent dye that binds to various proteins and lipids in the systemic circulation. The WTD increased plasma levels of total and HDL cholesterol 1.8- and …
