Varriano, M. Brodeur, D. P. Burdette, J. A. Clark, D. Lascar, K. D. Launey, P. Mueller, D. Ray, K. S. Sharma, A. A. Valverde, G. L. Wilson, X. L. Yan

Faculty Publications

A precision measurement of the β+ decay of B8 was performed using the Beta-decay Paul Trap to determine the β-ν angular correlation coefficient aβν. The experimental results were combined with new ab initio symmetry-adapted no-core shell-model calculations to yield the second-most precise measurement from Gamow-Teller decays, aβν=-0.3345±0.0019stat±0.0021syst. This value agrees with the standard model value of -1/3 and improves uncertainties in B8 by nearly a factor of 2. By combining results from B8 and Li8, a tight limit on tensor current coupling to right-handed neutrinos was obtained. A recent global evaluation of all other precision β decay studies suggested a …

Broad-Spectrum Lignin-Based Adhesives Using Thiol–Silyl Ether Crosslinkers, Yishayah Bension, Siteng Zhang, Tristan Menninger, Ting Ge, Chuanbing Tang

Faculty Publications

Lignin is a renewable feedstock that is abundant and inexpensive but still presents challenges for its valorization. In this work, we converted functionalized lignin into broad-spectrum adhesives using thiol–silyl ether crosslinkers. The curing behavior of adhesives was investigated via rheology of their resin forms. These materials exhibit good adhesion on diverse substrates, including wood, glass, steel, aluminium, carbon fiber, and different plastics, with the most adhesion strength in the range of 1–3 MPa. These adhesives were also explored for applications, ranging from wet conditions to different mechanically responsive materials. The mechanism of adhesion was further examined to understand the bonding …

Belowground Exploration By Trees And Shrubs, Francis E. Putz, Charles D. Canham, Scott V. Ollinger

Faculty Publications

Unlike trees, shrubs (i.e., multiple-stemmed woody plants) do not need evenly spaced large diameter structural roots and therefore should be more responsive to heterogeneous distributions of soil resources and spread further per unit belowground biomass. We therefore hypothesized that compared to trees, shrubs respond more to asymmetric distributions of nutrients, reach nutrient-rich patches of soil faster, and do so with less below-ground biomass. To test these three hypotheses, we planted individual seedlings of shrubs (Cornus racemosa, Rhus glabra, and Viburnum dentatum) and trees (Acer rubrum, Betula populifolia, and Fraxinus americana) in the centers of sand-filled rectangular boxes. In one direction …

Faculty Publications

Background

Sleep problems are associated with abnormal cardiovascular biomarkers and an increased risk of cardiovascular diseases (CVDs). However, studies investigating associations between sleep problems and CVD biomarkers have reported conflicting findings. This study examined the associations between sleep problems and CVD biomarkers in the United States.

Methods

Data were from the National Health and Nutrition Examination Survey (NHANES) (2007–2018) and analyses were restricted to adults ≥ 20 years (n = 23,749). CVD biomarkers [C-reactive Protein (CRP), low-density lipoproteins, high-density lipoproteins (HDL), triglycerides, insulin, glycosylated hemoglobin (HbA1c), and fasting blood glucose] were categorized as abnormal or normal using standardized cut-off …

Covering The Care: Health Insurance Coverage In New Hampshire | 2023 Update, Kelly Dixon, Deborah Fournier, Rebecca Simon

Faculty Publications

The rate of individuals without health insurance in New Hampshire has continued to decrease in recent years, with a rate of 5.1% in 2021 and 4.9% in 2022. This pattern aligns with the national rate of uninsured individuals; in 2021, 8.6% of the US population did not have health insurance, and 8.0% in 2022. Compared to other states in New England, New Hampshire remains in the middle with respect to its rate of uninsured residents. Maine’s uninsured rate was 5.7% in 2021 and 6.6% in 2022, while Massachusetts’ rate was 2.5% in 2021 and 2.4% in 2022.

Colectivo Moriviví: Reconfiguring The Puerto Rican Nation Through Feminist Art Activism, Tania Carrasquillo Hernandez

Faculty Publications

This article analyzes national identity construction in Puerto Rico in terms of gender dynamics and how contemporary artistic production has questioned patriarchal constructions within the nation. I argue that by voicing the narratives of Puerto Rican communities in the public sphere, Colectivo Moriviví validates the active participation and contribution of women, Afro-descendant minorities, and LGTBQ+ groups within the national body, forcing the national discourse to re-envision its purpose, values, and mission

Automated Reinforcement During Large-Scale Additive Manufacturing: Structural Assessment Of A Dual Approach, Hassan Ahmed, Ilerioluwa Giwa, Daniel Game, Gabriel Arce, Hassan Noorvand, Marwa Hassan, Ali Kazemian

Faculty Publications

Automated and seamless integration of reinforcement is one of the main unresolved challenges in large-scale additive construction. This study leverages a dual-reinforcement solution consisting of high-dosage steel fiber (up to 2.5% by volume) and short vertical reinforcements as a complementary reinforcement technique for 3D-printed elements. The mechanical performance of the printing material was characterized by measuring the compressive, flexural, and uniaxial tensile strengths of mold-cast specimens. Furthermore, the flexural performance of the plain and fiber-reinforced 3D-printed beams was evaluated in the three main loading directions (X, Y, and Z-directions in-plane). In addition, short vertical threaded reinforcements were inserted into the …

Generative Artificial Intelligence And Building Design: Early Photorealistic Render Visualization Of Façades Using Local Identity-Trained Models, Hayoung Jo, Jin Kook Lee, Yong Cheol Lee, Seungyeon Choo

Faculty Publications

This paper elucidates an approach that utilizes generative artificial intelligence (AI) to develop alternative architectural design options based on local identity. The advancement of AI technologies has increasingly piqued the interest of the architecture, engineering, construction, and facility management industry. Notably, the topic of "visualization"has gained prominence as a means for enhancing communication related to a project, especially in the early phases of design. This study aims to enhance the ease of obtaining design images during initial phases of design by drawing from multiple texts and images. It develops an additional training model to generate various design alternatives that resonate …

User Fee Programs, Erika Lietzan

Faculty Publications

A user fee is a fee assessed by the government when it provides a good or service to a private party. Classic examples include the fee to enter Yellowstone National Park and payment to the U.S. Postal Service for a first-class postage stamp. In these transactions, the government provides a specific benefit to an identifiable recipient, who pays the fee. Although the federal government has assessed user fees since this country's founding, broad authorizing legislation in the middle of the 20th century made it possible for agencies to craft user fee programs on their own initiative. Interest in relying on …

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 …

Modernizing The Medical Malpractice Standard Of Care, Philip G. Peters Jr.

Faculty Publications

The standard of care for health care providers proposed by section 5 of the Restatement of the Law Third, Torts: Medical Malpractice marks a fundamental shift in the American Law Institute's position on professional tort liability. According to both conventional wisdom and prior Restatement provisions, the standard of care for physicians is determined by their customary practices. Professionals alone are given the unique privilege to set their own legal standard of care. However, the proposed section 5 departs from this position. Instead, reasonable care for health care providers is defined as conduct "regarded as competent" by medical peers. Customary practices …

Creation Of Bound Half-Fermion Pairs By Solitons, Sapan Karki, Brett Altschul

Faculty Publications

In the presence of topologically nontrivial bosonic field configurations, the fermion number operator may take on fractional eigenvalues, because of the existence of zero-energy fermion modes. The simplest examples of this occur in 1+1 dimensions, with zero modes attached to kink-type solitons. In the presence of a kink-antikink pair, the two associated zero modes bifurcate into positive and negative energy levels with energies ±ge^-gΔ, in terms of the Yukawa coupling g≪1 and the distance Δ between the kink and antikink centers. When the kink and antikink are moving, it seems that there could be Landau–Zener-like transitions between these …

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 …

"I Am Become Death, The Destroyer Of Worlds": Applying Strict Liability To Artificial Intelligence As An Abnormally Dangerous Activity, Renee Henson

Faculty Publications

Artificial intelligence (AI)-enabled tools have produced a myriad of injuries, up to and including death. This burgeoning technology has caused scholars to ask questions, such as, How do we create a legal framework for AI? Because AI creators have acknowledged that even they do not know the capacities of their technology for good or bad outcomes, this Article argues that an existing framework, strict liability, is an appropriate fit for harms arising from this new technology because a party need not prove negligence to prevail. Strict liability was uniquely developed to handle those activities that are “abnormally dangerous.” An abnormally …

Ceratocystis Fimbriata Alters Root System Architecture And Causes Symptom Development Only In Detached Storage Roots In Bayou Belle And Beauregard Sweet Potato, Arthur Q. Villordon, Catherine D. Derobertis, Christopher A. Clark

Faculty Publications

Little is known about how the sweet potato (Ipomoea batatas) root system responds to Ceratocystis fimbriata in the growth substrate. Understanding whether the fungus affects the root system before harvest of storage roots (SR) could guide timing of management efforts. Cuttings of cultivars Bayou Belle and Beauregard, both previously considered susceptible to black rot, were in unamended or infested sand. At the onset of SR formation, effects on first- and second-order lateral root (LR) length and number among and within treatments, cultivars and replicate experiments were recorded. First-order LR length in inoculated Bayou Belle plants was 31% greater than in …

Insecticide Susceptibilities And Enzyme Activities Of Four Stink Bug Populations In Mississippi, Usa, Yuzhe Du, Shane Scheibener, Yu Cheng Zhu, K. Clint Allen, Gadi V.P. Reddy

Faculty Publications

In Mississippi, the Pentatomidae complex infesting soybean is primarily composed of Euschistus servus, Nezara viridula, Chinavia hilaris, and Piezodorus guildinii. This study employed spray bioassays to evaluate the susceptibilities of these stink bugs to seven commonly used formulated insecticides: oxamyl, acephate, bifenthrin, λ-cyhalothrin, imidacloprid, thiamethoxam, and sulfoxaflor. Stinks bugs were collected from soybeans in Leland, MS, USA during 2022 and 2023, as well as from wild host plants in Clarksdale, MS. There was no significant difference in the susceptibility of C. hilaris to seven insecticides between two years, whereas P. guildinii showed slightly increased susceptibility to neonicotinoids in 2023. Among …

Faculty Publications

The polyphagous fall armyworm (FAW), Spodoptera frugiperda, has become an invasive pest worldwide in recent years. To develop maize germplasm with multiple pest resistance and understand genetic inheritance, 12 experimental hybrids (six pairs of reciprocal crosses) with diverse genetic backgrounds and four commercial checks were examined for FAW resistance in 2013 and 2014. The experiment utilized a randomized complete block design with four replications as the block factor. FAW injury on maize plants was assessed at 7 and 14 d after the artificial infestation at the V6 stage, and predatory arthropod taxa and abundance on maize seedlings were recorded 7 …

Illumina 16s Rrna Gene Sequencing Dataset Of Bacterial Communities Of Soil Associated With Ironwood Trees (Casuarina Equisetifolia) In Guam, Tao Jin, Robert L. Schlub, Claudia Husseneder

Faculty Publications

Ironwood trees, which are of great importance for the economy and environment of tropical areas, were first discovered to suffer from a slow progressive dieback in Guam in 2002, later referred to as ironwood tree decline (IWTD). A variety of biotic factors have been shown to be associated with IWTD, including putative bacterial pathogens Ralstonia solanacearum and Klebsiella species (K. variicola and K. oxytoca), the fungus Ganoderma australe, and termites. Due to the soilborne nature of these pathogens, soil microbiomes have been suggested to be a significant factor influencing tree health. In this project, we sequenced the microbiome in the …

Relational Turbulence And Couples’ Convergence And Divergence In Weekly Highs And Lows During Three Months Of The Covid-19 Pandemic Lockdown, Shaochun Li, Denise Haunani Solomon, Kellie St Cyr Brisini

Faculty Publications

Previous research has found relational benefits of interpersonal emotional convergence. Drawing on relational turbulence theory, we expected that partners’ convergence in emotional high and low points is associated with relational uncertainty, qualities of interdependence, and relational turbulence. These hypotheses were tested using data retrieved from a longitudinal project in which spouses in 64 American married couples independently reported high and low experiences and completed relationship measures every week for ten weeks from June to August of 2020. Results from multilevel models confirmed some of the hypothesized benefits of convergence in highs, but predictions about convergence in lows were largely unsupported. …

Callous–Unemotional Traits And Emotion Perception Accuracy And Bias In Youths, Enrica Ciucci, Andrea Baroncelli, Carolina Facci, Stefania Righi, Paul J. Frick

Faculty Publications

This study investigated the associations among conduct problems, callous–unemotional (CU) traits, and indices of emotion recognition accuracy and emotion recognition bias obtained from human faces. Impairments in emotion recognition were considered within broader, impaired emotional and social functioning. The sample consisted of 293 middle-school students (51.19% girls; M age = 12.97 years, SD = 0.88 years). In general, CU traits were associated with less accuracy in recognizing emotions, especially fearful and angry faces, and such deficits in emotional recognition were not associated with conduct problems independent of CU traits. These results support the importance of studying potential deficits in the …

Preferential Hydrologic States And Tipping Characteristics Of Global Surface Soil Moisture, Vinit Sehgal, Binayak P. Mohanty

Faculty Publications

A dynamic transition in soil hydrologic states through meteorological variability and terrestrial feedback governs soil-vegetation-climate (SVC) interactions, constrained by critical soil moisture (SM) thresholds. However, observational and scaling constraints limit critical SM threshold estimation at the remote-sensing (RS) footprint scale. Using global surface SM (θRS) from NASA’s Soil Moisture Active Passive (SMAP) satellite, we characterize the seasonal preferential hydrologic states of θRS and derive three tipping characteristics to estimate the intensity (Mean Tipping Depth, (Formula presented.)), frequency (Tipping Count, η), and duration (Mean Tipped Time, (Formula presented.)) of the excursion of θRS from wet- to dry-average conditions. The preferential state …

Objective: To investigate the effect of a 16-week Tai Chi practice on strength, tactile sensation, kinesthesia, and static postural control among older adults of different age groups. Methods: This is a quasi-experimental study. Thirteen participants aged 60–69 years (60–69yr), 11 aged 70–79 years (70–79yr), and 13 aged 80–89 years (80–89yr) completed 16 weeks of 24-form Tai Chi practice. Their ankle and hip peak torque, tactile sensation, ankle and knee kinesthesia, and the root mean square of the center of pressure (Cop-RMS) were measured before (week 0) and after (week 17) practice. Results: 80–89yr showed less ankle plantar/dorsiflexion and hip abduction …

Embryonic Exposure To Benzotriazole Ultraviolet Stabilizer 327 Alters Behavior Of Rainbow Trout Alevin, Andreas N.M. Eriksson, Justin Dubiel, Lauren Zink, Zhe Lu, Jon A. Doering, Steve Wiseman

Faculty Publications

Benzotriazole ultraviolet (UV) stabilizers (BUVSs) are used in great quantities during industrial production of a variety of consumer and industrial goods. As a result of leaching and spill, BUVSs are detectable ubiquitously in the environment. As of May 2023, citing concerns related to bioaccumulation, biomagnification, and environmental persistence, (B)UV(S)-328 was recommended to be listed under Annex A of the Stockholm Convention on Persistent Organic Pollutants. However, a phaseout of UV-328 could result in a regrettable substitution because the replacement chemical(s) could cause similar or unpredicted toxicity in vivo, relative to UV-328. Therefore, the influence of UV-327, a potential replacement of …

Evaluation Of Organic And Synthetic Herbicide Applications On Weed Suppression In A Conventional Cropping System In Louisiana, Caitlin Denux, Aixin Hou, Lisa Fultz

Faculty Publications

Synthetic herbicides, with their varying modes of action, are well known for their efficiency in the suppression and control of weed species in U.S. agriculture. However, the consequences of using synthetic herbicides without attention to the surrounding environment produce chemical run-off, changes in soil health and soil health conditions, and create herbicide-resistant weeds. These outcomes have encouraged growers to seek alternative methods for their weed management programs or farming operations. Organic production systems and organic pesticides have helped address these challenges related to sustainability and environmental health. However, the use of organic herbicides in a conventional cropping system is not …

Stimulation Of Small Phytoplankton Drives Enhanced Sinking Particle Formation In A Subtropical Ocean Eddy, Haoran Liu, Thomas J. Browning, Edward A. Laws, Yibin Huang, Lei Wang, Yiwei Shang, Xiaogang Xing, Kuanbo Zhou, Zong Pei Jiang, Xin Liu, Bangqin Huang, Minhan Dai

Faculty Publications

Nutrient transfer into the sunlit surface ocean by cyclonic eddies is potentially crucial for sustaining primary productivity in the stratified subtropical gyres. However, the nature of productivity enhancements, including the flow of matter to higher trophic levels and its impact on carbon fluxes, remain poorly resolved. Here, we report a detailed assessment of the biogeochemical response to a cyclonic eddy in the subtropical Northwest Pacific via a combination of ship-based and autonomous platforms. Primary production was enhanced twofold within the eddy core relative to reference sites outside, whereas phytoplankton biomass even decreased. Pico-phytoplankton (< 2 μm) dominated (> 80%) both phytoplankton biomass and primary …

Faculty Publications

We present Fermi Gamma-ray Burst Monitor (Fermi-GBM) and Swift Burst Alert Telescope (Swift-BAT) searches for gamma-ray/X-ray counterparts to gravitational-wave (GW) candidate events identified during the third observing run of the Advanced LIGO and Advanced Virgo detectors. Using Fermi-GBM onboard triggers and subthreshold gamma-ray burst (GRB) candidates found in the Fermi-GBM ground analyses, the Targeted Search and the Untargeted Search, we investigate whether there are any coincident GRBs associated with the GWs. We also search the Swift-BAT rate data around the GW times to determine whether a GRB counterpart is present. No counterparts are found. Using both the Fermi-GBM Targeted Search …

Homology Growth, Hyperbolization, And Fibering, Grigori Avramidi, Boris Okun, Kevin Schreve

Faculty Publications

We introduce a hyperbolic reflection group trick which builds closed aspherical manifolds out of compact ones and preserves hyperbolicity, residual finiteness, and—for almost all primes p—-homology growth above the middle dimension. We use this trick, embedding theory and manifold topology to construct Gromov hyperbolic 7-manifolds that do not virtually fiber over a circle out of graph products of large finite groups.

Faculty Publications

We present the results of the first X-ray polarimetric observation of the low-mass X-ray binary 4U 1957+115, performed with the Imaging X-ray Polarimetry Explorer in May 2023. The binary system has been in a high-soft spectral state since its discovery and is thought to host a black hole. The ∼571 ks observation reveals a linear polarisation degree of 1.9% ± 0.6% and a polarisation angle of −41^◦. 8 ± 7^◦. 9 in the 2–8 keV energy range. Spectral modelling is consistent with the dominant contribution coming from the standard accretion disc, while polarimetric data suggest a significant role …
