Ion Heating By A Fast Magnetosonic Turbulence In The Solar Corona, Sergei A. Markovskii, Bernard J. Vasquez

Faculty Publications

Observational data at heliocentric distances of tens of solar radii suggest that fast magnetosonic modes make up a considerable fraction of the solar wind fluctuations. Furthermore, this fraction appears to increase closer to the Sun. We carry out three-dimensional kinetic simulations with particle ions and fluid electrons to evaluate the proton and alpha-particle heating produced by the damping of the fast waves in the solar corona. Realistic parameters at 5 solar radii, including the fluctuation amplitude, are used. We show that, due to the cyclotron resonance, the alphas are heated preferentially perpendicularly to the magnetic field and much more strongly …

Deep Selenium Donors In Zngep2 Crystals: An Electron Paramagnetic Resonance Study Of A Nonlinear Optical Material, Timothy D. Gustafson, Larry E. Halliburton, Nancy C. Giles, Peter G. Schunemann, Kevin T. Zawilski, J. Jesenovec, Kent L. Averett, Jonathan E. Slagle [*]

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 …

Systematic Review On The Impacts Of Agricultural Interventions On Food Security And Nutrition In Complex Humanitarian Emergency Settings, Melodie Al Daccache, Berthe Abi Zeid, Leila Hojeij, Ghassan Baliki, Tilman Brück, Hala Ghattas Ph.D.

Faculty Publications

Complex humanitarian emergencies are a main driver of food and nutritional insecurity. Agricultural interventions are key to improving nutrition and food security, and their positive impacts are well-documented in stable developing countries. However, it is unclear if their positive effects on food security hold in complex emergency settings, too. In this paper, we systematically review empirical articles that apply rigorous designs to assess the causal impacts of agricultural interventions on food security, nutrition, or health outcomes in complex humanitarian emergencies. We only find six articles matching these criteria, which have mixed results on dietary diversity and food security, and little …

Single-Cell Transcriptional Landscapes Of Bovine Peri-Implantation Development, Giovanna Nascimento Scatolin, Hao Ming, Yinjuan Wang, Rajan Iyyappan, Emilio Gutierrez-Castillo, Linkai Zhu, Masroor Sagheer, Chao Song, Kenneth Bondioli, Zongliang Jiang

Faculty Publications

Supporting healthy pregnancy outcomes requires a comprehensive understanding of the molecular and cellular programs of peri-implantation development, when most pregnancy failure occurs. Here, we present single-cell transcriptomes of bovine peri-implantation embryo development at day 12, 14, 16, and 18 post-fertilization. We defined the cellular composition and gene expression of embryonic disc, hypoblast, and trophoblast lineages in bovine peri-implantation embryos, and identified markers and pathway signaling that represent distinct stages of bovine peri-implantation lineages; the expression of selected markers was validated in peri-implantation embryos. Using detailed time-course transcriptomic analyses, we revealed a previously unrecognized primitive trophoblast cell lineage. We also characterized …

Messaging About Very Low Nicotine Cigarettes (Vlncs) To Influence Policy Attitudes, Harm Perceptions And Smoking Motivations: A Discrete Choice Experiment, Reed M. Reynolds, Lucy Popova, David L. Ashley, Katherine C. Henderson, Charity A. Ntansah, Bo Yang, Emily E. Hackworth, James Hardin, Jim F. Thrasher Ph.D., Ma, Ms

Faculty Publications

Background To reduce smoking and the harms it causes, countries, including the USA, are considering policies to reduce nicotine in combustible tobacco to minimally addictive levels. Effective messages about very low nicotine cigarettes (VLNCs) and this policy are crucial in combating misperceptions threatening the policy’s effectiveness.

Data and methods A discrete choice experiment assessed messages about VLNCs. Participants were 590 adults who smoked exclusively, 379 adults who both smoked and used e-cigarettes, 443 adults who formerly smoked and 351 young adults who never smoked (total n=1763). Seven message attributes were varied systematically (source, harm, chemicals, nicotine, satisfaction, addictiveness and quitting …

From Pumps And Pipes To Data And Discovery: Unifying A New Division, Jeremy Myntti, Megan Mcmillan

Faculty Publications

A reorganization of the Brigham Young University Library in 2020 brought many changes to the library, including the formation of the Metadata and Information Technology (MIT) Division. This new division needed to define a vision for itself, encourage a sense of unity among its employees, and foster collaboration among those employees. This article details how the MIT Division created a Data and Discovery initiative based on the Pumps and Pipes collaboration model, a model which brings seemingly unrelated industries together to discover solutions to their respective challenges by exploring “their neighbor’s toolbox” (Pumps and Pipes, n.d., “What We Do”).

Faculty Publications

This paper presents a building-level post-hazard functionality model for communities exposed to flood hazards including the interdependencies between the population, buildings, and infrastructure. An existing portfolio of building archetypes is used to model the post-hazard physical flood functionality of different building typologies within the community with the goal of supporting resilience-informed decision-making. Specific fragility-based flood functionality curves were developed for this portfolio to quantify the exceedance probability of a prescribed set of functionality states. While the physical functionality of buildings is significant to the total functionality of a building and community resilience assessment, the functionality of utilities such as power …

Generating Rate Features For Mobile Applications, Shristi Shrestha, Anas Mahmoud

Faculty Publications

Mobile application (app) stores employ standardized mechanisms for rating hosted apps, typically in the form of free text reviews and numerical rating scales. App users use these mechanisms to express their opinions about their apps and discover apps that fit their specific needs. However, existing app rating systems do not take into account the operational characteristics of application domains. Thus, generated user reviews are often short, subjective, and one-dimensional. To overcome these limitations, in this paper, we propose a multi-dimensional rating system for mobile apps. Our assumption is that an adaptive goal-based app rating system can prompt users to generate …

Blocks? Graphs? Why Not Both? Designing And Evaluating A Hybrid Programming Environment For End-Users, Nico Ritschel, Felipe Fronchetti, Reid Holmes, Ronald Garcia, David C. Shepherd

Faculty Publications

Many modern end-user development environments support one of two visual modalities: block-based programming or data-flow programming. In this work, we investigate the trade-offs between the two modalities in the context of robotics tasks. These often contain both aspects that are better solved with blocks and others that best fit data-flow programming. To address this style of task, we present and discuss two novel programming environment prototypes, one purely block-based and one a hybrid of blocks and data-flow programming. We compare the designs through a controlled experiment with 113 end-user participants, in which we asked them to solve programming and program …

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 …

Complex Dayside Particle Precipitation Observed During The Passage Of A Solar Wind Rotational Discontinuity, Simon Wing, Jean Berchem, C Philippe Escoubet, Charles J. Farrugia

Faculty Publications

The dayside particle precipitation during the passage of a solar wind rotational discontinuity (RD) event on 10 April 2015 is examined and reviewed. The RD leads to complex structures at the magnetopause, boundary layer, mantle, and cusp even though the geomagnetic activity level remains low. Particle precipitation data from DMSP F17 reveal the formation of an unusual boundary layer where the low energy (cold) ions exhibit energy-latitude dispersion that is usually associated with mantle while the high energy (hot) ions look like typical magnetospheric ions. DMSP F17 and F19 observe a double cusp that is a signature of magnetic reconnection …

Probing The Electrode-Electrolyte Interface Of Sodium/Glyme-Based Battery Electrolytes, Dodangodage Ishara Senadheera, Orlando Carrillo-Bohorquez, Ernest O. Nachaki, Ryan Jorn, Daniel G. Kuroda, Revati Kumar

Faculty Publications

Sodium-ion batteries (NIBs) are promising systems for large-scale energy storage solutions; yet, further enhancements are required for their commercial viability. Improving the electrochemical performance of NIBs goes beyond the chemical description of the electrolyte and electrode materials as it requires a comprehensive understanding of the underlying mechanisms that govern the interface between electrodes and electrolytes. In particular, the decomposition reactions occurring at these interfaces lead to the formation of surface films. Previous work has revealed that the solvation structure of cations in the electrolyte has a significant influence on the formation and properties of these surface films. Here, an experimentally …

Lithium Ion Speciation In Cyclic Solvents: Impact Of Anion Charge Delocalization And Solvent Polarizability, Ernest O. Nachaki, Daniel G. Kuroda

Faculty Publications

The increasing demand for lithium batteries has triggered the search for safer and more efficient electrolytes. Insights into the atomistic description of electrolytes are critical for relating microscopic and macroscopic (physicochemical) properties. Previous studies have shown that the type of lithium salt and solvent used in the electrolyte influences its performance by dictating the speciation of the ionic components in the system. Here, we investigate the molecular origins of ion association in lithium-based electrolytes as a function of anion charge delocalization and solvent chemical identity. To this end, a family of cyano-based lithium salts in organic solvents, having a cyclic …

Background

Cognitive impairment has multiple risk factors spanning several domains, but few studies have evaluated risk factor clusters. We aimed to identify naturally occurring clusters of risk factors of poor cognition among middle-aged and older adults and evaluate associations between measures of cognition and these risk factor clusters.

Methods

We used data from the National Health and Nutrition Examination Survey (NHANES) III (training dataset, n = 4074) and the NHANES 2011–2014 (validation dataset, n = 2510). Risk factors were selected based on the literature. We used both traditional logistic models and support vector machine methods to construct a composite score …

Molecular design is a critical aspect of various scientific and industrial fields, where the properties of molecules hold significant importance. In this study, a 3-fold methodology design is presented that leverages the power of generative artificial intelligence (AI), predictive modeling, and reinforcement learning to create tailored molecules with desired properties. This model synergistically combines deep learning techniques with Self-Referencing Embedded Strings (SELFIES) molecular representation to build a generative model that generates valid molecules and a graphical neural network model that accurately forecasts molecular properties. The Variational Autoencoder (VAE) coupled with reinforcement learning helps refine molecule generation based on targeted attributes. …

Magnetic Control Of Nonmagnetic Living Organisms, Ahmed Al Harraq, Min Feng, Hashir M. Gauri, Ram Devireddy, Ankur Gupta, Qing Sun, Bhuvnesh Bharti

Faculty Publications

Living organisms inspire the design of microrobots, but their functionality is unmatched. Next-generation microrobots aim to leverage the sensing and communication abilities of organisms through magnetic hybridization, attaching magnetic particles to them for external control. However, the protocols used for magnetic hybridization are morphology specific and are not generalizable. We propose an alternative approach that leverages the principles of negative magnetostatics and magnetophoresis to control nonmagnetic organisms with external magnetic fields. To do this, we disperse model organisms in dispersions of Fe3O4 nanoparticles and expose them to either uniform or gradient magnetic fields. In uniform magnetic fields, living organisms align …

Mineral particles provide reactive sites for organic carbon (C) to bind in soil this 'mineral-associated organic matter' (MAOM) may persist for centuries to millennia or cycle rapidly in minutes to days. The conditions and processes that influence short and long-term cycling of MAOM are poorly constrained. Soil moisture is one key control on organic matter cycling in soil, and projected shifts in moisture regimes towards more intense rainfall and prolonged drought under climate change may alter MAOM formation and cycling. Here, in a 3-week laboratory incubation study, we evaluated how two contrasting moisture regimes affected the formation and cycling of …

The impact of cancer cachexia on the colonic microbiota is poorly characterized. This study assessed the effect of two cachectic-producing tumor types on the gut microbiota to determine if a similar dysbiosis could be found. In addition, it was determined if a diet containing an immunonutrient-rich food (walnuts) known to promote the growth of probiotic bacteria in the colon could alter the dysbiosis and slow cachexia. Male Fisher 344 rats were randomly assigned to a semi-purified diet with or without walnuts. Then, within each diet group, rats were further assigned randomly to a treatment group: tumor-bearing ad libitum fed (TB), …
