Investigating the Bromoform Membrane Interactions Using Atomistic Simulations and Machine Learning: Implications for Climate Change Mitigation.

Methane emissions from livestock contribute to global warming. Seaweeds used as food additive offer a promising emission mitigation strategy because seaweeds are enriched in bromoform─a methanogenesis inhibitor. Therefore, understanding bromoform storage and production in seaweeds and particularly in a cell-like environment is crucial.

Improving ready-to-eat meat safety: Evaluating the bacterial-inactivation efficacy of microplasma-based far-UVC light treatment of food-contact surfaces and deli turkey breast.

The safety of ready-to-eat (RTE) deli meats, especially those sliced in retail establishments, may be improved by light-based surface decontamination. Conventional 254 nm ultraviolet-C (UVC) systems have strong germicidal effects but pose human-health hazards that make them unsuitable for retail use. This study therefore explores the efficacy of microplasma-based 222 nm far-UVC lamps as a safer alternative for decontaminating liquid buffer, two common food-contact surfaces (polyethylene terephthalate and stainless steel), and RTE turkey breast.

Differential antigenic imprinting effects between influenza H1N1 hemagglutinin and neuraminidase in a mouse model.

Unlabelled: Understanding how immune history influences influenza immunity is essential for developing effective vaccines and therapeutic strategies. This study examines the antigenic imprinting of influenza hemagglutinin (HA) and neuraminidase (NA) using a mouse model with sequential infections by H1N1 virus strains exhibiting substantial antigenic differences in HA. In our pre-2009 influenza infection model, we observed that mice with more extensive infection histories produced higher levels of functional NA-inhibiting antibodies (NAI).

Late Pleistocene onset of mutualistic human/canid ( spp.) relationships in subarctic Alaska.

Large canids (wolves, dogs, and coyote) and people form a close relationship in northern (subarctic and arctic) socioecological systems. Here, we document the antiquity of this bond and the multiple ways it manifested in interior Alaska, a region key to understanding the peopling of the Americas and early northern lifeways. We compile original and existing genomic, isotopic, and osteological canid data from archaeological, paleontological, and modern sites.

On the pressure dependence of viscosity, especially for fluids that have a tendency to form glasses.

Understanding fluid viscosity is crucial for applications including lubrication and chemical kinetics. A commonality of molecular models is that they describe fluid flow based on the availability of vacant space. The proposed analysis builds on Goldstein's idea that viscous transport must involve the concerted motion of a molecular ensemble, referred to as cooperatively rearranging regions (CRRs) by Adam and Gibbs in their entropy-based viscosity model for liquids close to their glass transition.

A systematic review of using population-level human mobility data to understand SARS-CoV-2 transmission.

The emergence of SARS-CoV-2 into a highly susceptible global population was primarily driven by human mobility-induced introduction events. Especially in the early stages, understanding mobility was vital to mitigating the pandemic prior to widespread vaccine availability. We conducted a systematic review of studies published from January 1, 2020, to May 9, 2021, that used population-level human mobility data to understand SARS-CoV-2 transmission.

Managing the tradeoff between reproduction and survival requires flexibility in behaviour and gene regulation in three-spined stickleback.

Predators exert a powerful selective force, however, predator avoidance can conflict with other important activities such as attracting mates. Decisions over whether to court mates versus avoiding predators are vital to fitness, yet the mechanistic underpinnings of how animals manage such tradeoffs are poorly understood. Here, we investigate the flexibility of behaviour and gene regulation in response to a tradeoff between avoiding predators (survival) and courting potential mates (reproduction) in three-spined stickleback ().

Multistep Removal System of Gaseous Toluene: Adsorption, Electrochemical, and Photolytic Treatments.

A large amount of atmospheric emissions result from various anthropogenic activities worldwide. Given the complexity of volatile organic compounds (VOCs) and their different adsorption capacities, redox potentials, and photolytic properties, an air purification system for the removal of VOCs that combines multiple physical processes was proposed in this study using toluene as an example. These processes include, in the first step, an adsorption treatment (AT) with activated carbon (AC), where toluene adsorption results from the insertion of aromatic rings (nonpolar groups) between the graphitic carbon planes, as demonstrated by the Raman spectroscopy; in the second step, electrochemical treatment (ECT) using TiO|Ti||SS-304 electrodes applying an electric field to accelerate the oxidation of toluene through the production of free radicals (⋅OH), hydroperoxyl radicals and benzyl groups, followed by the rupture of aromatic rings to generate aliphatic compounds and the consequent mineralization to CO, CO, and HO; in the third step, photolytic treatment (PT) with a 254-nm UV lamp for toluene degradation is used, which is influenced by the addition of radicals, such as ⋅OH or ⋅O , to transform toluene into either benzene or phenol.

Immunometabolic effects of -carotene and vitamin A in atherogenesis.

Carotenoids are a diverse group of lipids produced by photosynthetic organisms, and therefore, these compounds are major components of healthy diets. Carotenoids are among the most extensively studied micronutrients to date due to their antioxidant and provitamin A properties. -carotene is one of the most abundant carotenoids in our diet, but more importantly, it is the main vitamin A precursor in humans.

Review and revamp of compositional data transformation: A new framework combining proportion conversion and contrast transformation.

Due to the development of next-generation sequencing technology and an increased appreciation of their role in modulating host immunity and their potential as therapeutic agents, the human microbiome has emerged as a key area of interest in various biological investigations of human health and disease. However, microbiome data present a number of statistical challenges not addressed by existing methods, such as the varying sequencing depth, the compositionality, and zero inflation. Solutions like scaling and transformation methods help to mitigate heterogeneity and release constraints, but often introduce biases and yield inconsistent results on the same data.

Exploring risk and protective factors of intimate partner violence in Korean young adults.

Intimate partner violence (IPV) is most prevalent in young adults, yet scarce evidence is available regarding South Korean young adults' experience of IPV and culturally tailored IPV prevention programs. To address this gap, this study aimed to holistically assess IPV victimization and perpetration rates and the related risk and protective factors among Korean young adults. Using online survey data from 600 Korean young adults using simple random sampling, this study found that the lifetime prevalence of both IPV victimization and perpetration was about 30%.

An Anechoic, High-Fidelity, Multidirectional Speech Corpus.

Introduction: We currently lack speech testing materials faithful to broader aspects of real-world auditory scenes such as speech directivity and extended high frequency (EHF; > 8 kHz) content that have demonstrable effects on speech perception. Here, we describe the development of a multidirectional, high-fidelity speech corpus using multichannel anechoic recordings that can be used for future studies of speech perception in complex environments by diverse listeners.

Design: Fifteen male and 15 female talkers (21.

Ruijsenaars wavefunctions as modular group matrix coefficients.

We give a description of the Hallnäs-Ruijsenaars eigenfunctions of the 2-particle hyperbolic Ruijsenaars system as matrix coefficients for the order 4 element acting on the Hilbert space of (2) quantum Teichmüller theory on the punctured torus. The (2) Macdonald polynomials are then obtained as special values of the analytic continuation of these matrix coefficients. The main tool used in the proof is the cluster structure on the moduli space of framed (2)-local systems on the punctured torus, and an -equivariant embedding of the (2) spherical DAHA into the quantized coordinate ring of the corresponding cluster Poisson variety.

Application of selenium isotopes to define selenium bioreduction in coal waste rock: Elk Valley, British Columbia.

Anthropogenic sources of selenium (Se), including coal mining, can release Se to the environment and raise Se concentrations in receiving waters above drinking water and aquatic limits. Selenium bioreduction can be an important control to reduce dissolved selenate concentrations. This extensive study investigated the application of Se stable isotope ratios (δSe) of dissolved selenate to identify Se bioreduction in saturated and unsaturated mine rock piles (MRPs) located in the Elk Valley, Canada.

Development of vegetative oil sorghum: From lab-to-field.

Biomass crops engineered to accumulate energy-dense triacylglycerols (TAG or 'vegetable oils') in their vegetative tissues have emerged as potential feedstocks to meet the growing demand for renewable diesel and sustainable aviation fuel (SAF). Unlike oil palm and oilseed crops, the current commercial sources of TAG, vegetative tissues, such as leaves and stems, only transiently accumulate TAG. In this report, we used grain (Texas430 or TX430) and sugar-accumulating 'sweet' (Ramada) genotypes of sorghum, a high-yielding, environmentally resilient biomass crop, to accumulate TAG in leaves and stems.
