Properties Of Relativistic Electron Precipitation: A Comparative Analysis Of Wave-Induced And Field Line Curvature Scattering Processes, Luisa Capannolo, Andrew Staff, Wen Li, Katharine Duderstadt, Nithin Sivadas, Joshua Pettit, Sadie Elliot, Murong Qin, Xiao-Chen Shen, Qianli Ma

Faculty Publications

We analyze the properties of relativistic (&gt700 keV) electron precipitation (REP) events measured by the low-Earth-orbit (LEO) POES/MetOp constellation of spacecraft from 2012 through 2023. Leveraging the different profiles of REP observed at LEO, we associate each event with its possible driver: waves or field line curvature scattering (FLCS). While waves typically precipitate electrons in a localized radial region within the outer radiation belt, FLCS drives energy-dependent precipitation at the edge of the belt. Wave-driven REP is detected at any MLT sector and L shell, with FLCS-driven REP occurring only over the nightside–a region where field line stretching is frequent. …

Master Narratives Surrounding Rural Emerging Adult Migration: Resources For Postsecondary Decision-Making In Rural Communities, Cindy Hartman, Jayson Seaman, Andrew D. Coppens, Erin H. Sharp, Sarah Jusseaume

Faculty Publications

This study examined the cultural messages informing postsecondary decision-making processes surrounding emerging adult migration from/to a predominately rural state in the northeastern U.S. Utilizing an ecological approach to sampling, this study used 27 interviews and 5 focus groups of stakeholders working in educational, employment, and quality of life sectors. Narrative analysis yielded evidence of a predominant master narrative of migration as a developmental requirement during emerging adulthood. Stakeholders spoke of normative and prescriptive expectations that emerging adults particularly in rural areas orient their plans and decision-making around, including leaving their home communities for developmental reasons. Implications for emerging adult development …

I’ll talk about some inspirational examples of the pairing of courage and creativity in my …

Constraining Accreted Neutron Star Crust Shallow Heating With The Inferred Depth Of Carbon Ignition In X-Ray Superbursts, Zachary P. Meisel

Faculty Publications

Evidence has accumulated for an as-yet unaccounted for source of heat located at shallow depths within the accreted neutron star crust. However, the nature of this heat source is unknown. I demonstrate that the inferred depth of carbon ignition in X-ray superbursts can be used as an additional constraint for the magnitude and depth of shallow heating. The inferred shallow heating properties are relatively insensitive to the assumed crust composition and carbon fusion reaction rate. For low-accretion rates, the results are weakly dependent on the duration of the accretion outburst, so long as accretion has ensued for enough time to …

Single-Molecule Profiling Of Per- And Polyfluoroalkyl Substances By Cyclodextrin Mediated Host-Guest Interactions Within A Biological Nanopore, Xiaojun Wei, Aditya Choudhary, Leon Y. Wang, Lixing Yang, Mark J. Uline, Mario Tagliazucchi, Qian Wang, Dmitry Bedrov, Chang Liu

Faculty Publications

Biological nanopores are increasingly used in molecular sensing due to their single-molecule sensitivity. The detection of per- and polyfluoroalkyl substances (PFAS) like perfluorooctanoic acid and perfluorooctane sulfonic acid is critical due to their environmental prevalence and toxicity. Here, we investigate selective interactions between PFAS and four cyclodextrin (CD) variants (α-, β-, γ-, and 2-hydroxypropyl-γ-CD) within an α-hemolysin nanopore. We demonstrate that PFAS molecules can be electrochemically sensed by interacting with a γ-CD in a nanopore. Using HP-γ-CDs with increased steric resistance, we can identify homologs of the perfluoroalkyl carboxylic acid and the perfluoroalkyl sulfonic acid families and detect common PFAS …

Ignis: A One-Dimensional Laminar Flame Code, Jansen P. Berryhill, Jacob K. Spinti, David O. Lignell

Faculty Publications

Laminar flame codes have an important role in combustion modeling. They can provide a fundamental understanding of flame dynamics and provide a basis for building subgrid scale models in turbulent flow simulations. This paper presents Ignis, an open-source laminar flame code with the capability to offload submodels, like soot formation and radiation, using external packages and libraries. Ignis is written in C++, is documented with Doxygen, and is available on GitHub. It contains three different flame formulations: diffusion flames, premixed flames, and laminar flamelets solved in the mixture fraction coordinate. An option to facilitate creation of a diffusion flame table …

Regimes Of Stratified Turbulence At Low Prandtl Number, Kasturi Shah, Gregory P. Chini, Colm-Cille P. Caulfield, Pascale Garaud

Faculty Publications

Quantifying transport by strongly stratified turbulence in low Prandtl number ( $Pr$ ) fluids is critically important for the development of better models for the structure and evolution of stellar and planetary interiors. Motivated by recent numerical simulations showing strongly anisotropic flows suggestive of a scale-separated dynamics, we perform a multiscale asymptotic analysis of the governing equations. We find that, in all cases, the resulting slow–fast systems take a quasilinear form. Our analysis also reveals the existence of several distinct dynamical regimes depending on the emergent buoyancy Reynolds and Péclet numbers, $Re_b = \alpha ^2 Re$ and $Pe_b = Pr …

Short Communication: Numerically Simulated Time To Steady State Is Not A Reliable Measure Of Landscape Response Time, Nicole M. Gasparini, Adam M. Forte, Katherine R. Barnhart

Faculty Publications

Quantifying the timescales over which landscapes evolve is critical for understanding past and future environmental change. Computational landscape evolution models are one tool among many that have been used in this pursuit. We compare numerically modeled times to reach steady state for a landscape adjusting to an increase in rock uplift rate. We use three different numerical modeling libraries and explore the impact of time step, grid type, numerical method for solving the erosion equation, and metric for quantifying the time to steady state. We find that modeled time to steady state is impacted by all of these variables. Time …

Contrasting Responses Of Commercially Important Northwest Atlantic Bivalve Species To Ocean Acidification And Temperature Conditions, Teagan Mcmahon, Diana Thatcher, Branwen Williams, Alan Wanamaker, Brittany Jellison, Heidi Franklin, Katherine Guay, Nina M. Whitney, Joseph A. Stewart, Michèle Lavigne

Faculty Publications

Modern calcifying marine organisms face numerous environmental stressors, including overfishing, deoxygenation, increasing ocean temperatures, and ocean acidification (OA). Coastal marine settings are predicted to become warmer and more acidic in coming decades, heightening the risks of extreme events such as marine heat waves. Given these threats, it is important to understand the vulnerabilities of marine organisms that construct their shells from calcium carbonate, which are particularly susceptible to warming and decreasing pH levels. To investigate the response of four commercially relevant bivalve species to OA and differing temperatures, juvenile Mercenaria mercenaria (hard shell clams), juvenile Mya arenaria (soft shell clams), …

Heavy Molecular And Metallic Ions In The Magnetosphere, M Yamauchi, S Christon, I Dandouras, S Haaland, D Kastinen, Lynn M. Kistler, I Mann, S Nozawa, J M C Plane, Y Saito, L Schulz, S Watababe, P Wurz, A W. Yau

Faculty Publications

Observations and present knowledge of heavy ions with mass ≥ 27 in the magnetosphere are reviewed. There are four ultimate sources of these heavy ions: the solar wind (mainly high charge-state atomic ions), the ionosphere (mainly molecular ions), the atmospheric metal layers that originate ultimately from ablation of meteoroids and possibly space debris (low charge-state metallic ions and metal-rich molecular ions), and lunar surface and exosphere (low charge-state metallic and molecular ions). The upstream heavy ions (solar wind origin and lunar origin) give independent information on the ion entry routes to the magnetosphere from proton (H+) and alpha particles (He++): …

Activist Archivists: Centering Marginalized Campus Voices And Rebuilding Institutional Knowledge Through Oral History, Kai H. Uchida

Faculty Publications

The rapidly changing face of the UNH system, retirements spurred by COVID, and a challenging financial environment motivated SCA to restructure the ways that they collect and preserve institutional history. Through a two-year pilot program utilizing a new technology called TheirStory -- which hosts, records, transcribes, and stores interviews -- they began plans to record histories from University leadership, faculty, staff, alumni, and students. This poster recounts how the University Archivist shaped the UNH Oral History Project to fill in the institutional gaps of its past, considers how this project forms a microcosm of his curatorial and collection vision as …

Neville Fletcher's Vibrant Valve Voyage, Whitney L. Coyle

Faculty Publications

Fletcher's seminal 1993 paper explores the dynamics of pressure-controlled valves critical in sound production for woodwind and brass instruments and animal vocalizations.1 The study examines four simple valve configurations, determined by the effect of overpressures on valve openings. It identifies conditions under which these valves can sustain self-sustained oscillations, particularly when the ducts connected to the valves are shorter than a quarter of the wavelength at the valve's resonant frequency. The research focuses on the initiation of small amplitude oscillations, setting the stage for understanding larger amplitude nonlinear oscillations.

Assessing The Influence Of Occupancy Factors On Energy Performance In Us Small Office Buildings, Seddigheh Norouziasl, Sorena Vosoughkhosravi, Amirhosein Jafari, Zhihong Pang

Faculty Publications

Office buildings are responsible for about 35% of the total electricity in the US and over 70% of building energy consumption occurs during occupancy periods. Therefore, understanding occupancy behavior is crucial for reducing building energy consumption. However, given the stochastic nature of occupant behavior, identifying which occupancy parameters have the most impact on energy consumption poses a considerable challenge. This study aims to investigate and quantify the impact of various occupancy parameters on the energy performance of a US small-sized office building using an EnergyPlus-based nationwide energy simulation. First, dynamic occupancy schedules are created based on different occupancy parameters using …

Integrative Highway Rights-Of-Way Management To Reduce Stormwater Run-Off And Enhance Habitat, Madeline M. Showers, Robin M. Rotman

Faculty Publications

Nature-based management along highway rights-of-way (ROW) has been a focus in several states to benefit pollinators through supporting diverse and native vegetative communities. There is the potential to enhance the ecological benefits of this practice by integrating stormwater management into restoration plans and incorporating other complex, multidisciplinary factors. Historically, lack of technical assistance and limited resources has led managers to use unsustainable roadside practices that reduce the potential ecological services of the ROW; however, integrative management can aid in the prioritization of management efforts and link objectives of various resource agencies. In this literature review, we address the ecological impacts …

Sculpting Success: The Importance Of Diet And Physical Activity To Support Skeletal Muscle Health During Weight Loss With New Generation Anti-Obesity Medications, Gregory J. Grosicki, Nikhil V.

Faculty Publications

Obesity is a public health crisis, with prevalence rates tripling over the past 60 y. Although lifestyle modifications, such as diet and physical activity, remain the first-line treatments, recent anti-obesity medications (AOMs) have been shown to achieve greater reductions in body weight and fat mass. However, AOMs also reduce fat-free mass, including skeletal muscle, which has been demonstrated to account for 20% to 50% of total weight loss. This can equate to ∼6 kg or 10% of total lean mass after 12–18 mo, a loss comparable to a decade of human aging. Despite questions surrounding the clinical relevance of weight …

Model Mediation Course Syllabus With Teaching Notes, John Lande

Faculty Publications

This course syllabus grows out of a series of articles developing Real Practice Systems Theory in mediation practice and education. This course would teach students about mediation of legal disputes in the US, including the roles of both mediators and attorneys. There is great value in teaching students about both roles of mediators and attorneys in the same course. Practitioners in both roles share some basic values and principles, and they need to understand each others’ roles and typical techniques in mediation.

The syllabus discusses the roles of attorneys, mediators, and parties, procedures before and during mediation sessions, and the …

Creating Educational Value By Teaching Law Students To Be Quasi-Mediators, John Lande

Faculty Publications

Most mediation courses currently focus primarily on mediators’ perspectives and interventions during mediation sessions. Under the traditional view, mediators are the intervenors, and the parties, attorneys, and other participants in mediation sessions are the intervenees.

This article argues that mediation courses should provide balanced instruction of the roles of both mediators and attorneys by teaching students how to function as “quasi-mediators” when representing clients in mediation. As quasi-mediators, attorneys look for opportunities to reach reasonable agreements whenever appropriate, and they use mediation techniques to move the process in that direction. But they do not surrender their loyalty to their clients …

Bostock And The Forgotten Eeoc, Sandra F. Sperino

Faculty Publications

In Bostock v. Clayton County, Georgia, the Supreme Court formally recognized that federal discrimination law prohibits discrimination based on sexual orientation and gender identity. The opinion barely mentioned the Equal Employment Opportunity Commission (EEOC), the federal agency charged with enforcing federal discrimination law. Reading Bostock, it would be easy to get the impression that the EEOC played little to no role in the outcome. This Essay reclaims and restores the EEOC's role.

In restoring the EEOC's role in this story, two themes emerge. First, Bostock's methodology erases the administrative agency tasked with enforcing Title VII in ways that are inconsistent …

Online Eye Tracking For Aphasia: A Feasibility Study Comparing Web And Lab Tracking And Implications For Clinical Use, Willem S. Van Boxtel, Michael Linge, Rylee Manning, Lily N. Haven, Jiyeon Lee

Faculty Publications

Background & Aims: Studies using eye-tracking methodology have made important contributions to the study of language disorders such as aphasia. Nevertheless, in clinical groups especially, eye-tracking studies often include small sample sizes, limiting the generalizability of reported findings. Online, webcam-based tracking offers a potential solution to this issue, but web-based tracking has not been compared with in-lab tracking in past studies and has never been attempted in groups with language impairments. Materials & Methods: Patients with post-stroke aphasia (n = 16) and age-matched controls (n = 16) completed identical sentence-picture matching tasks in the lab (using an EyeLink system) and …

Assessing Dimensions Of Thought Disorder With Large Language Models: The Tradeoff Of Accuracy And Consistency, Samuel L. Pugh, Chelsea Chandler, Alex S. Cohen, Catherine Diaz-Asper, Brita Elvevåg, Peter W. Foltz

Faculty Publications

Natural Language Processing (NLP) methods have shown promise for the assessment of formal thought disorder, a hallmark feature of schizophrenia in which disturbances to the structure, organization, or coherence of thought can manifest as disordered or incoherent speech. We investigated the suitability of modern Large Language Models (LLMs - e.g., GPT-3.5, GPT-4, and Llama 3) to predict expert-generated ratings for three dimensions of thought disorder (coherence, content, and tangentiality) assigned to speech samples collected from both patients with a diagnosis of schizophrenia (n = 26) and healthy control participants (n = 25). In addition to (1) evaluating the accuracy of …

Interactive Effects Of Co2, Temperature, And Nutrient Limitation On The Growth And Physiology Of The Marine Coccolithophore Emiliania Huxleyi (Prymnesiophyceae), James P. Bradley, Edward A. Laws

Faculty Publications

The marine coccolithophore Emiliania huxleyi (strain PnB 272 B10) was grown in a continuous culture system on a 12:12 light:dark cycle at temperatures from 10 °C to 28 °C under either nutrient-replete or nitrate-limited conditions and at either 493 ppmv (low) or 1003 ppmv (high) partial pressures of CO2 (pCO2). The maximum and minimum nutrient-replete growth rates were 0.751 d⁻¹ at 20 °C and 0.365 d⁻¹ at 10 °C, respectively. Ratios of particulate organic carbon (POC) to particulate inorganic carbon (PIC) were independent of pCO2 and of the degree of nitrate limitation but were temperature dependent and lower …

Discovery of pulsations from a number of ultra-luminous X-ray (ULX) sources proved that accretion onto neutron stars can produce luminosities exceeding the Eddington limit by several orders of magnitude. The conditions necessary to achieve such high luminosities as well as the exact geometry of the accretion flow in the neutron star vicinity are, however, a matter of debate. The pulse phase-resolved polarization measurements that became possible with the launch of the Imaging X-ray Polarimetry Explorer (IXPE) can be used to determine the pulsar geometry and its orientation relative to the orbital plane. They provide an avenue to test different theoretical …

Recent observations of X-ray pulsars (XRPs) performed by the Imaging X-ray Polarimetry Explorer (IXPE) have made it possible to investigate the intricate details of these objects in a new way, thanks to the added value of X-ray polarimetry. Here we present the results of the IXPE observations of SMC X-1, a member of the small group of XRPs displaying super-orbital variability. SMC X-1 was observed by IXPE three separate times during the high state of its super-orbital period. The observed luminosity in the 2- 8 keV energy band of L ∼ 2 × 10³⁸ erg s^{- 1} makes …

Underrepresented Minority Faculty In The Usa Face A Double Standard In Promotion And Tenure Decisions, Theodore Masters-Waage, Christiane Spitzmueller, Ebenezer Edema-Sillo, Ally St. Aubin, Michelle Penn-Marshall, Erika Henderson, Peggy Lindner, Cynthia Werner, Tracey Rizzuto, Juan Madera

Faculty Publications

Underrepresented minority (URM) faculty face challenges in many domains of academia, from university admissions to grant applications. We examine whether this translates to promotion and tenure (P&T) decisions. Data from five US universities on 1,571 faculty members’ P&T decisions show that URM faculty received 7% more negative votes and were 44% less likely to receive unanimous votes from P&T committees. A double standard in how scholarly productivity is rewarded is also observed, with below-average h-indexes being judged more harshly for URM faculty than for non-URM faculty. This relationship is amplified for faculty with intersectional backgrounds, especially URM women. The differential …

The Effects Of Anthropogenic Stressors On Above- And Belowground Phytochemical Diversity Of The Wetland Grass, Phragmites Australis, Andrea E. Glassmire, Ana L. Salgado, Rodrigo Diaz, Joseph Johnston, Laura A. Meyerson, Joshua S. Snook, James T. Cronin

Faculty Publications

Coastal wetlands face threats from climate change-induced flooding and biological invasions. Plants respond to these stressors through changes in their phytochemical metabolome, but it is unclear whether stressors affecting one tissue compartment (e.g., leaves) create vulnerabilities in others (e.g., roots) or elicit similar responses across tissues. Additionally, responses to multiple simultaneous stressors remain poorly understood due to the focus on individual metabolites in past studies. This study aims to elucidate how the phytochemical metabolome of three Phragmites australis (Cav.) lineages, common in the Mississippi River Delta, responds to flooding and infestation by the non-native scale insect Nipponaclerda biwakoensis (Kuwana). Among …

Supersolvable Posets And Fiber-Type Abelian Arrangements, Christin Bibby, Emanuele Delucchi

Faculty Publications

We present a combinatorial analysis of fiber bundles of generalized configuration spaces on connected abelian Lie groups. These bundles are akin to those of Fadell–Neuwirth for configuration spaces, and their existence is detected by a combinatorial property of an associated finite partially ordered set. This is consistent with Terao’s fibration theorem connecting bundles of hyperplane arrangements to Stanley’s lattice supersolvability. We obtain a combinatorially determined class of K(π,1) toric and elliptic arrangements. Under a stronger combinatorial condition, we prove a factorization of the Poincaré polynomial when the Lie group is noncompact. In the case of toric arrangements, this provides an …
