Dynamic Volunteer Engagement And Impactful Educational Outreach Taking Us Into The Next 50 Years Of The Extension Master Gardener Program, Heather Kirk-Ballard, Kristine M. Lang, Esther Mcginnis, Kerry Smith, Lucy Bradley

Faculty Publications

According to the 2021 Extension Master Gardener (EMG) National Summary, the EMG Volunteer Program had an estimated 84,700 volunteers throughout the United States. These volunteers helped communities garden and grow food, provided opportunities to engage in activities that improved physical and mental health, and worked on projects that addressed environmental issues. In total, these programs contributed 3.1 million hours of education to local communities and $88 million dollars in value to the public. However, the COVID-19 pandemic presented challenges for the program, with many states implementing reduced requirements and increased flexibility for volunteers. The workshop “Dynamic Volunteer Engagement and Impactful …

Ecological Factors Of Telemental Healthcare Utilization Among Adolescents With Increased Substance Use During The Covid-19 Pandemic: The Moderating Effect Of Gender, Youn Kyoung Kim, Eusebius Small, Rachel D. Pounders, Salimata Lala Fall, Wendy L. Wilson

Faculty Publications

Background: Adolescent substance use is often associated with concurrent mental health problems (e.g., depression, suicide attempts, parental emotional and physical abuse, not feeling close to people at school, and lower virtual connectedness) at multiple ecological levels. Objective: This study examined whether such risk factors among adolescents were associated with the use of telemental healthcare (TMHC) and whether gender moderated these associations. Methods: Data were drawn from the Adolescent Behaviors and Experiences Survey, collected by the U.S. Centers for Disease Control and Prevention from January to June 2021. A hierarchical multiple logistic regression analysis was conducted using a national sample of …

Effects Of Metformin On Glucose Metabolism And Mitochondrial Function In Patients With Obstructive Sleep Apnea: A Pilot Randomized Trial, Elizabeth R.M. Zunica, Elizabeth C. Heintz, Wagner S. Dantas, R. Caitlin Hebert, Ma Kayla Tanksley, Robbie A. Beyl, Edward C. Mader, John P. Kirwan, Christopher L. Axelrod, Prachi Singh

Division of Basic Science Faculty Publications

Obstructive sleep apnea (OSA) is associated with increased risk for diabetes, and standard treatment with positive airway pressure (PAP) device shows inconsistent effects on glucose metabolism. Metformin is known to treat and prevent diabetes, but its effects on skeletal muscle mitochondrial function are not completely understood. Here, we evaluate the effects of metformin on glucose metabolism and skeletal muscle mitochondrial function in patients with OSA. Sixteen adults with obesity (50.9 ± 6.7 years, BMI: 36.5 ± 2.9 kg/m2) and moderate-to-severe OSA were provided with PAP treatment and randomized to 3 months of placebo (n = 8) or metformin (n = …

Co-Designing A Community Lifestyle Intervention Program To Reduce Postpartum Weight Retention, Maureen Makama, Helen Skouteris, Lisa J. Moran, Briony Hill, Leanne M. Redman, Siew Lim

Decay Of Multi-Point Correlation Functions In Zd, Rui Han, Fan Yang

Faculty Publications

We prove multi-point correlation bounds in Z^d for arbitrary d≥1 with symmetrized distances, answering open questions proposed by Sims–Warzel (Commun Math Phys 347(3):903–931, 2016) and Aza–Bru–Siqueira Pedra (Commun Math Phys 360(2):715–726, 2018). As applications, we prove multi-point correlation bounds for the Ising model on Z^d, and multi-point dynamical localization in expectation for uniformly localized disordered systems, which provides the first examples of this conjectured phenomenon by Bravyi–König (Commun Math Phys 316(3):641–692, 2012).

Short-Term Sediment Dispersal On A Large Retreating Coastal River Delta Via 234th And 7be Sediment Geochronology: The Mississippi River Delta Front, Andrew Courtois, Samuel Bentley, Jillian Maloney, Kehui Xu, Jason Chaytor, Ioannis Y. Georgiou, Michael D. Miner, Jeffrey Obelcz, Navid H. Jafari, Melanie Damour

Faculty Publications

Many Mississippi River Delta studies have shown recent declines in fluvial sediment load from the river and associated land loss. In contrast, recent sedimentary processes on the subaqueous delta are less documented. To help address this knowledge gap, multicores were collected offshore from the three main river outlets at water depths of 25–280 m in June 2017 just after the peak river discharge period, with locations selected based on 2017 U.S. Geological Survey seabed mapping. The coring locations included the undisturbed upper foreset, mudflow lobes, gullies, and the undisturbed prodelta. Nine multicores were analyzed for Beryllium-7 activity, and four cores …

Hartley, T. Lauritsen, S. Marley, G. E. Morgan, C. Müller-Gatermann, S. Nandi, W. Reviol, D. Santiago-Gonzalez, G. Savard, D. Seweryniak, Ir B. Vasilev, J. Wu

Faculty Publications

Excited structures in Ce146 were populated in β decay of the high-spin state in the neutron-rich nucleus La146. The beam was produced by the Californium Rare Isotope Breeder Upgrade (CARIBU) facility at Argonne National Laboratory, reaccelerated by the ATLAS accelerator, and implanted on a moving-tape system in the middle of the GAMMASPHERE array. The decay scheme of the high-spin, β-decaying state in La146 was revised with respect to previous studies and evaluated nuclear data. The structure of La146 is discussed in the framework of the deformed Nilsson model and systematics of known quasiparticle structures in the region.

Quantum Scalar Fields Interacting With Quantum Black Hole Asymptotic Regions, Rodolfo Gambini, Jorge Pullin

Faculty Publications

We continue our work on the study of spherically symmetric loop quantum gravity coupled to two spherically symmetric scalar fields, with one that acts as a clock. As a consequence of the presence of the latter, we can define a true Hamiltonian for the theory. In previous papers, we studied the theory for large values of the radial coordinate, i.e., far away from any black hole or star that may be present. This makes the calculations considerably more tractable. We have shown that in the asymptotic region, the theory admits a large family of quantum vacua for quantum matter fields …

Thermoelectric Properties Of Snse And Snse2 Single Crystals, Abhinna Rajbanshi, Daniel Duong, Eklavya Thareja, Williams A. Shelton, Rongying Jin

Faculty Publications

Thermoelectric materials can serve for conversion between thermal and electrical energy. In the search for thermoelectric materials, layered SnSe and SnSe2 are promising candidates. We have successfully synthesized SnSe and SnSe2 single crystals by the modified Bridgman method and studied their thermoelectric properties: thermopower (S), thermal conductivity (κ), and electrical conductivity (σ) in the temperature range between 2 and 400 K, which are absent in the literature. The kink observed in the thermopower corresponds to the metallic-nonmetallic crossover temperature for both SnSe and SnSe2, reflecting their inherent electronic nature. Compared with SnSe2, >100 K, we find that SnSe exhibits higher …

Engineering A Non-Hermitian Second-Order Topological Insulator State In Quasicrystals, Chakradhar Rangi, Ka Ming Tam, Juana Moreno

Faculty Publications

Non-Hermitian topological phases have gained immense attention due to their potential to unlock novel features beyond Hermitian bounds. PT-symmetric (parity time-reversal symmetric) non-Hermitian models have been studied extensively over the past decade. In recent years, the topological properties of general non-Hermitian models, regardless of the balance between gains and losses, have also attracted vast attention. Here, we propose a non-Hermitian second-order topological (SOT) insulator that hosts gapless corner states on a two-dimensional quasicrystalline lattice (QL). We first construct a non-Hermitian extension of the Bernevig-Hughes-Zhang model on a QL generated by the Amman-Beenker tiling. This model has real spectra and supports …

Population and Public Health Science Faculty Publications

Background and Objective: One in five preschool children are overweight/obese, and increased weight status over time increases the risks of poorer future health. Motor skill competence may be a protective factor, giving children the ability to participate in health-enhancing physical activity. Yet, we do not know when the relationship between motor competence and weight status first emerges or whether it is evident across the body mass index (BMI) spectrum. This study examined the association between motor skill competence and BMI in a multi-country sample of 5545 preschoolers (54.36 ± 9.15 months of age; 50.5% boys) from eight countries. Methods: Quantile …

Lugli, Moira Maclean, David A. Paz-García, Marc Rius, Ethan G. Ross, Erick X. Treviño Balandra, James Vanstone, Suzanne T. Williams, Phillip B. Fenberg

Faculty Publications

Aim: The poleward range expansion of tropical species, and range contraction of temperate species (known as tropicalisation) has mainly been studied from an ecological perspective, with little research on its genetic consequences. Here, we used distributional and genetic data to document the consequences of tropicalisation in rocky shore gastropods and assess more broadly the future implications of tropicalisation on phylogeographic patterns. Location: Nineteen sampling sites along >3000 km of the eastern Pacific rocky intertidal zone, from the tip of the Baja California Peninsula to southern California. Taxon: Temperate gastropods: Lottia conus, L. strigatella, Fissurella volcano and Tegula gallina. Tropical gastropods: …

Irrigation Of Sand-Based Creeping Bentgrass Putting Greens With Nanobubble-Oxygenated Water, Eric J. Deboer, Michael D. Richardson, John H. Mccalla

Faculty Publications

Cultural and environmental factors can place creeping bentgrass (Agrostis stolonifera) under extreme stress during the summer months. This stress, coupled with the growth adaptation of creeping bentgrass, can result in shallow, poorly rooted stands of turf. To enhance root zone oxygen and rooting of creeping bentgrass, golf courses use methods such as core and solid-tine aerification, and sand topdressing. An additional method of delivering oxygen to the soil could be irrigation with nanobubble-oxygenated water. The properties of nanobubbles (NBs) allow for high gas dissolution rates in water. Irrigating with NB-oxygenated water sources may promote increased rooting of creeping bentgrass putting …

Hamiltonian Formulation And Symplectic Split-Operator Schemes For Time-Dependent Density-Functional-Theory Equations Of Electron Dynamics In Molecules, François Mauger, Cristel Chandre, Mette B. Gaarde, Kenneth Lopata, Kenneth J. Schafer

Faculty Publications

We revisit Kohn–Sham time-dependent density-functional theory (TDDFT) equations and show that they derive from a canonical Hamiltonian formalism. We use this geometric description of the TDDFT dynamics to define families of symplectic split-operator schemes that accurately and efficiently simulate the time propagation for certain classes of DFT functionals. We illustrate these with numerical simulations of the far-from-equilibrium electronic dynamics of a one-dimensional carbon chain. In these examples, we find that an optimized 4th order scheme provides a good compromise between the numerical complexity of each time step and the accuracy of the scheme. We also discuss how the Hamiltonian structure …

Prevalence Of Drifting Osteons Distinguishes Human Bone, Katherine M. French, Sophia R. Mavroudas, Victoria M. Dominguez

Publications and Research

The histological, or microscopic, appearance of bone tissue has long been studied to identify species-specific traits. There are several known histological characteristics to discriminate animal bone from human, but currently no histological characteristic that has been consistently identified in human bone exclusive to other mammals. The drifting osteon is a rare morphotype found in human long bones and observationally is typically absent from common mammalian domesticates. We surveyed previously prepared undecalcified histological sections from 25 species (human n = 221; nonhuman primate n = 24; nonprimate n = 169) to see if 1) drifting osteons were indeed more common in …

The Origins And Future Of International Data Privacy Law, Julian Schneider

UC Law SF International Law Review

Data privacy law varies widely across jurisdictions worldwide. Amidst sophistries and jurisdictional conflicts between lawmakers in Europe and the United States, a largely unregulated cross-border data industry emerged, prepared to exploit an unaware or overwhelmed general public. Without governmental support, privacy itself is in grave danger. The people, as true bearers of the fundamental right to privacy, must be put back in control of their data by governments that are aware of their ever-conflicting roles as protectors and aggressors. Scholars like Ari Ezra Waldman, in its book “Industry Unbound,” have criticized the common notice and consent approach to privacy as …

Eliminating Bias In The Courtroom? A Content Analysis Of Judges’ Opinions Regarding Implicit Bias Training, Teyah S. Giannetta, Audrey L. Cerfoglio, Monica K. Miller

University of Memphis Law Review

The threat of implicit biases in people’s decision making is increasing. Unlike explicit biases, implicit biases are more covert and harder to identify. Research on implicit bias has increased substantially over the past few decades due to increasing disparities within the legal and criminal justice systems. Disparities result in minorities and underrepresented populations suffering due to the unjust decision-making of courtroom players. Previous research on implicit bias states that the more education a person receives about their biases, the less likely those biases will impact their decisions. To combat these disparities, we recommend implementing implicit bias training to reduce implicit …

Beps: Endgame, Adam H. Rosenzweig

University of Memphis Law Review

By all accounts the international tax regime is facing a transformational moment marking the end of international tax avoidance by multinational corporations through a concerted global effort at tax reform spearheaded by the Organization for Economic Cooperation and Development (“OECD”) under its Base Erosion and Profit Shifting (“BEPS”) project. BEPS initially began as a technical project to identify and propose remedies for many of the more complex and persistent planning techniques in cross-border taxation. After a series of remarkably successful breakthroughs, however, the scope of BEPS grew into a much more ambitious project with the OECD identifying fifteen specific action …

Interacting With Korean Sijo Poetry Through Stereoscopic Reading, Katerina R. Bucek

ALL - Honors Theses

The process of stereoscopic reading highlights different aspects of a piece by using multiple translations and the source text in the same space. When applied to sijo, stereoscopic reading provides insight into both the meaning and art form of the poems, which could not be achieved through a single translation. Stereoscopic reading was introduced by translator and professor Jo Anne Engelbert as a method of reading and teaching foreign language texts. I argue that the stereoscopic reading method is compatible with Korean sijo in a way that reveals the complexity of the poems on both linguistic and stylistic levels and …

Fauna Associated With American Alligator (Alligator Mississippiensis) Nests In Coastal South Carolina, Usa, Thomas R. Rainwater, Randeep Singh, Clarissa A. Tuten, Aaron M. Given, Parker W. Gibbons, Bo Song, Steven G. Platt, Philip M. Wilkinson, Catherine M. Bodinof Jachowski

Biology

Crocodilians are considered to be “ecosystem engineers” because their modification of habitats provides opportunities for feeding, drinking, breeding, and other vital life activities to a wide variety of other animals. One such habitat modification is the construction of nest mounds during the breeding season by most crocodilian species, including American alligators (Alligator mississippiensis). While many reports exist describing wildlife associated with alligator nests, no studies have quantified faunal associates and their corresponding behaviors while visiting nests. To address this data gap, we used automated game cameras to monitor wildlife and their behaviors at alligator nests during the egg incubation period …

Classification Of Hybrid Chestnut Cultivars (Castanea Sativa) Registered In Türkiye With Artificial Neural Networks, Based On Some Physical Properties Of Their Nuts, Taner Yildiz

Turkish Journal of Agriculture and Forestry

Understanding how the classification and identification of biological species can evaluate improvements in newly developed cultivars, including chestnuts (Castanea sativa), is crucial for product processing and equipment design. To evaluate this, in the present study artificial neural networks (ANNs) were used to characterize four hybrid chestnut cultivars (Macit 55, Akyüz, and Ali Nihat registered in Türkiye and Bouche de Betizac registered in France). A backpropagation neural networks algorithm was used in the ANN approach based on nine physical properties. These properties included shelled nut weight and volume, sphericity, geometric mean diameter, bulk density, surface area, true density, porosity, and length, …

Zinc And Manganese Effect Seed Quality And Germination In Common Bean (Phaseolus Vulgaris L.), Mehrdad Yarnia, Masoud Soltani̇ Bouljak, Parisa Bolouri, İnci̇ Tolay

Turkish Journal of Agriculture and Forestry

Zinc (Zn) and manganese (Mn) are important micronutrients in plant growth and development. In this study, the effect of Zn and Mn sulfate treatments at different growth stages of mother plants in common bean on seed production and germination potential was carried out. Results showed that zinc sulfate (ZnSo4) treatments significantly affected yield and pod number per plant compared to manganese sulfate tetrahydrate (MnSO4) treatments. Treatment in any form or at any stage of growth increased yield and its components in common bean. The highest efficiency of ZnSO4 was obtained in the pod production stage; MnSO4 enjoyed greater efficiency in …
