Twisted Spatiotemporal Optical Vortex Beams In Dispersive Media, Milo W. Hyde Iv Sep 2024

Twisted Spatiotemporal Optical Vortex Beams In Dispersive Media, Milo W. Hyde Iv

Faculty Publications

We derive a closed-form expression for the mutual coherence function (MCF) of a twisted spatiotemporal optical vortex (STOV) beam after propagating a distance in a linear dispersive medium. A twisted STOV beam is a partially coherent optical field that possesses a coherent STOV and a stochastic twist coupling its space and time dimensions. These beams belong to a special class of space–time-coupled light fields that carry transverse (to the direction of propagation) orbital angular momentum, making them potentially useful in numerous applications including quantum optics, optical manipulation, and optical communications. After presenting the derivation, we validate our new general MCF …


A Theory Of Genetic Dimensions In The Law, Ana Santos Rutschman, Yaniv Heled, Liza Vertinsky Jun 2024

A Theory Of Genetic Dimensions In The Law, Ana Santos Rutschman, Yaniv Heled, Liza Vertinsky

Faculty Publications

Since the biotechnology revolution of the 1970s, genetic science and genetic technology have captured the public imagination. They have become a centerpiece of how we understand ourselves, our relationship with other humans, other living beings, our environment, and—indeed—with the universe. Through this evolution of understanding, genetic phenomena have acquired many meanings, some rooted in objective reality and others subjective and dependent on individual perceptions and sentiments.

However, legal decision-making and policymaking have not kept pace and reflect only a partial understanding of the multiple dimensions of genetic phenomena, which are forced into narrowing legal pathways, neglecting vital interests. As the …


Borderline Personality Disorder Subtypes And Public Stigma, Seth A. Brown Jun 2024

Borderline Personality Disorder Subtypes And Public Stigma, Seth A. Brown

Faculty Publications

Despite high public stigma towards individuals with borderline personality disorder (BPD), no research has examined whether stigma differs among the various proposed BPD subtypes. The primary purpose of this research was to examine two potential contributors to stigma towards individuals with BPD: 1) gender, and 2) BPD subtype of the individuals. The three subtypes utilized in this study were emotional, low anxiety, and inhibited (Sleuwaegen, 2018). A total of 415 participants read 1 of 6 randomly assigned vignettes about an individual and then completed the Attribution Questionnaire which encompasses 6 aspects of stigma. Male individuals (featured in a vignette) led …

Effects Of Rf Signal Eventization Encoding On Device Classification Performance, Michael J. Smith, Michael A. Temple, James W. Dean May 2024

Effects Of Rf Signal Eventization Encoding On Device Classification Performance, Michael J. Smith, Michael A. Temple, James W. Dean

Faculty Publications

The results of first-step research activity are presented for realizing an envisioned “event radio” capability that mimics neuromorphic event-based camera processing. The energy efficiency of neuromorphic processing is orders of magnitude higher than traditional von Neumann-based processing and is realized through synergistic design of brain-inspired software and hardware computing elements. Relative to event-based cameras, the development of event-based hardware devices supporting Radio Frequency (RF) applications is severely lagging and considerable interest remains in obtaining neuromorphic efficiency through event-based RF signal processing. In the Operational Technology (OT) protection arena, this includes efficient software computing capability to provide reliable device classification. A …


The Effect Of Visual Sensory Interference During Multitask Obstacle Crossing In Younger And Older Adults, Hyeyoung Cho, Shirley Rietdyk May 2024

The Effect Of Visual Sensory Interference During Multitask Obstacle Crossing In Younger And Older Adults, Hyeyoung Cho, Shirley Rietdyk

Faculty Publications

When older adults step over obstacles during multitasking, their performance is impaired; the impairment results from central and/or sensory interference. The purpose was to determine if sensory interference alters performance under low levels of cognitive, temporal, and gait demand, and if the change in performance is different for younger versus older adults. Participants included 17 younger adults (20.9±1.9 years) and 14 older adults (69.7±5.4 years). The concurrent task was a single, simple reaction time (RT) task: depress button in response to light cue. The gait task was stepping over an obstacle (8 m walkway) in three conditions: (1) no sensory …


Horizontal Subcontracting And The Global Factory, Peter J. Buckley, Michael Murphree, John Anderson May 2024

Horizontal Subcontracting And The Global Factory, Peter J. Buckley, Michael Murphree, John Anderson

Faculty Publications

The focus of this article is the examination of the factors that trigger the addition of horizontal subcontracting to the structure of global factories. Horizontal subcontracting takes place when one firm is contracted to produce a given item, fills as much of the order as they are able to based on their available capacity, and subsequently subcontracts the remainder to a qualitatively identical firm. We find that similar entrepreneurial backgrounds of contract manufacturers lead to strong business ties in the same industry and stage of production; low-cost, used production machinery and inexpensive factory rent lead to low barriers to entry; …

College Students' Perceptions And Opinions Of Their Physical Activity Instructor Being Caring In Class, David C. Barney, Kamora Shelton, Katelyn Rogers, Teresa Leavitt Dr.

Faculty Publications

College can be a very impressionable time for a student, both positively and negatively. One way the college experience can be positive is the interactions the student has with their professors/instructors (hereafter the term instructor will be used). One behavior the instructors can exhibit including in physical activity (PA) classes is being caring or showing caring behaviors toward students. The purpose of this study was to investigate college students’ perceptions of the impact of PA instructor caring behaviors toward the student. For this study 69 college students (45 males and 24 females) were surveyed with one open-ended survey question. It …

The research emphasizes the importance of strategic foresight as a complementary tool to traditional planning practices. Territorial foresight facilitates the exploration of complex future scenarios, fostering collaborative learning and a shared vision among stakeholders. The study proposes a shift towards a proactive, foresight-driven approach that can help break the vicious cycle …


Constitutional Rights And Remedial Consistency, Katherine Mims Crocker May 2024

Constitutional Rights And Remedial Consistency, Katherine Mims Crocker

Faculty Publications

When the Supreme Court declined definitively to block Texas’s S.B. 8, which effectively eliminated pre-enforcement federal remedies for what was then a plainly unconstitutional restriction on abortion rights, a prominent criticism was that the majority would have never tolerated the similar treatment of preferred legal protections—like gun rights. This refrain reemerged when California enacted a copycat regime for firearms regulation. This theme sounds in the deep-rooted idea that judge-made law should adhere to generality and neutrality values requiring doctrines to derive justification from controlling a meaningful class of cases ascertained by objective legal criteria.

This Article is about consistency, and …

Deterministic Global 3d Fractal Cloud Model For Synthetic Scene Generation, Aaron M. Schinder, Shannon R. Young, Bryan J. Steward, Michael L. Dexter, Andrew Kondrath, Stephen Hinton, Ricardo Davila

Faculty Publications

This paper describes the creation of a fast, deterministic, 3D fractal cloud renderer for the AFIT Sensor and Scene Emulation Tool (ASSET). The renderer generates 3D clouds by ray marching through a volume and sampling the level-set of a fractal function. The fractal function is distorted by a displacement map, which is generated using horizontal wind data from a Global Forecast System (GFS) weather file. The vertical windspeed and relative humidity are used to mask the creation of clouds to match realistic large-scale weather patterns over the Earth. Small-scale detail is provided by the fractal functions which are tuned to …

Faculty Publications

Zinc germanium diphosphide (ZnGeP2) is a ternary semiconductor best known for its nonlinear optical properties. A primary application is optical parametric oscillators operating in the mid-infrared region. Controlled donor doping provides a method to minimize the acceptor-related absorption bands that limit the output power of these devices. In the present study, a ZnGeP2 crystal is doped with selenium during growth. Selenium substitutes for phosphorus and serves as a deep donor. Significant concentrations of native defects (zinc vacancies, germanium-on-zinc antisites, and phosphorous vacancies) are also present in the crystal. Electron paramagnetic resonance (EPR) is used to establish the …

Pregnane X Receptor Signaling Pathway And Vitamin K: Molecular Mechanisms And Clinical Relevance In Human Health, Jeff Staudinger, Avina Mahroke, Gauri Patel, Cole Dattel, Sahana Reddy

Faculty Publications

This review explores the likely clinical impact of Pregnane X Receptor (PXR) activation by vitamin K on human health. PXR, initially recognized as a master regulator of xenobiotic metabolism in liver, emerges as a key regulator influencing intestinal homeostasis, inflammation, oxidative stress, and autophagy. The activation of PXR by vitamin K highlights its role as a potent endogenous and local agonist with diverse clinical implications. Recent research suggests that the vitamin K-mediated activation of PXR highlights this vitamin's potential in addressing pathophysiological conditions by promoting hepatic detoxification, fortifying gut barrier integrity, and controlling pro-inflammatory and apoptotic pathways. PXR activation by …


Preventing Sexual Harassment In Higher Education: A Framework For Prevention Science Program Development, Cindy A. Crusto, Lisa M. Hooper, Ishita S. Arora Apr 2024

Preventing Sexual Harassment In Higher Education: A Framework For Prevention Science Program Development, Cindy A. Crusto, Lisa M. Hooper, Ishita S. Arora

Faculty Publications

Sexual harassment is an intractable problem that harms the students, community, culture, and success of institutes of higher education (IHEs). The alarming prevalence of sexual harassment at IHEs highlights the urgent need for effective prevention programs. However, there are few empirically supported preventive interventions that effectively target the factors that most impact the determinants, trajectory, and short- and intermediate-term effects of sexual harassment. In this paper, we overview the problem of sexual harassment and propose an organizing framework to help IHEs develop effective interventions to prevent sexual harassment. Guided by prevention science, we propose a framework—modified from SAMHSA’s (2019) guidelines …

This article describes methods and findings from a study focused on youth living in rural communities in northern New Hampshire who struggle with accessing STEM learning opportunities for reasons including economic underinvestment and geographical isolation. These challenges also negatively impact researchers hoping to learn how rural youth benefit from informal STEM learning experiences, which contribute to low-project participation and retention rates. As in other amenity-rich rural areas, the communities in this study are promoting outdoor recreation as a vehicle for economic development. We wanted to understand if outdoor recreation activities tied to economic growth initiatives — activities which youth have …


State Constitutional Limitations To Cities Taxing The Digital Economy, Lauren Shores Pelikan Apr 2024

State Constitutional Limitations To Cities Taxing The Digital Economy, Lauren Shores Pelikan

Faculty Publications

The digital economy’s rapid evolution, most recently with the rise of artificial intelligence, demands a reevaluation of state constitutional limitations on local taxation of digital transactions. Citizens have long feared excessive or unfair tax burdens, hence the adoption of constitutional amendments that prohibit legislators from increasing taxes or imposing new taxes without a public vote. However, these constitutional limitations are now preventing cities from taxing digital transactions that are taking over the economy. This is a serious financial problem for cities whose traditional sources of tax revenue, such as sales taxes and property taxes, are dwindling due to the digitalizing …


Real Practice Systems Annotated Bibliography, John Lande Apr 2024

Real Practice Systems Annotated Bibliography, John Lande

Faculty Publications

Real Practice Systems (RPS) theory holds that practitioners’ practice systems are based on their personal histories, values, goals, motivations, knowledge, and skills as well as the parties and the cases in their work. RPS analysis can be used in many dispute resolution roles such as mediator, advocate in mediation, negotiator, and litigator generally. In mediation, practitioners develop categories of cases, parties, and behavior patterns that lead them to design routine procedures and strategies for dealing with recurring challenges before, during, and after mediation sessions.

RPS theory is the culmination of much of the work in my scholarly career. The bibliography …

Injury related to blast exposure dramatically rose during post-911 era military conflicts in Iraq and Afghanistan. Mild traumatic brain injury (mTBI) is among the most common injuries following blast, an exposure that may not result in a definitive physiologic marker (e.g., loss of consciousness). Recent research suggests that exposure to low level blasts and, more specifically repetitive blast exposure (RBE), which may be subconcussive in nature, may also impact long term physiologic and psychological outcomes, though findings have been mixed. For military personnel, blast-related injuries often occur in chaotic settings (e.g., combat), which create challenges in the immediate assessment of …

Given the emergence of China as a political and economic power in the 21st century, there is increased interest in analyzing Chinese news articles to better understand developing trends in China. Because of the volume of the material, automating the categorization of Chinese-language news articles by headline text or titles can be an effective way to sort the articles into categories for efficient review. A 383,000-headline dataset labeled with 15 categories from the Toutiao website was evaluated via natural language processing to predict topic categories. The influence of six data preparation variations on the predictive accuracy of four algorithms was …


A Quantum Logic Gate In The Dna Deoxyribose Moiety, F. Matthew Mihelic Mar 2024

A Quantum Logic Gate In The Dna Deoxyribose Moiety, F. Matthew Mihelic

Faculty Publications

The deoxyribose moiety of a nucleotide in the DNA molecule can act as a quantumlogic gate, in which the enantiomeric shift between the C2-endo and C3-endo conformations of each nucleotide, occurs within a logically and thermodynamically reversible situation of electron spin qubits, that are coherently held within the topologically insulating DNA crystalline nanostructure, and that are coherently conducted along the delocalized electrons of the pi-stacked nucleotide base pairs. The enantiomeric symmetry between the C2-endo and C3-endo conformations is logically and thermodynamically reversible because it functions as a symmetry-breaking Szilard engine that is effectively built out of the physicality of the …
