SARS-CoV-2 within-host population expansion, diversification and adaptation in zoo tigers, lions and hyenas.

SARS-CoV-2 rapidly adapts to new hosts following cross-species transmission; this is highly relevant as novel within-host variants have emerged following infection of susceptible wild and domestic animal species. Furthermore, SARS-CoV-2 transmission from animals (e.g.

Is Discrimination Widespread or Concentrated? Evaluating the Distribution of Anti-Black Discrimination in Judicial, Hiring, and Housing Decisions.

Is anti-Black discrimination concentrated among a discriminatory few, or widespread across many decision-makers? The handful of studies that have addressed this question have reached divergent conclusions, with some suggesting that discrimination follows the 80/20 rule (i.e., a Pareto distribution) and others suggesting that discrimination is normally distributed.

Adsorption grand potential of OH on metal oxide surfaces.

Context: Describing chemical processes at solid-liquid interfaces as a function of a fixed electron chemical potential presents a challenge for electronic structure calculations and is essential for understanding electrochemical phenomena. Grand Canonical Density Functional Theory (GCDFT) allows treating solid-liquid interfaces in such a way that studying the influence of a fixed electron potential arises naturally. In this work, GCDFT is used to compute the adsorption grand potential (AGP), a key parameter for understanding and predicting the behavior of adsorbates on surfaces.

Halorubrum miltondacostae sp. nov., a potential polyhydroxyalkanoate producer isolated from an inland solar saltern in Rio Maior, Portugal.

One hundred and sixty-three extreme halophiles were recovered from a single sample collected from an inland solar saltern in Rio Maior. Based on random amplified polymorphic DNA (RAPD) profiles and partial 16S rRNA gene sequencing 125 isolates were identified as members of the Archaea domain within the genus Halorubrum. Two strains, RMP-11 and RMP-47, showed 99.

Impact of memory bias in the dietary estimation of older adults measured through a food frequency questionnaire and weighed food records: A cross-sectional study in older adults and primary caregivers.

Introduction: changes in cognitive performance and memory of older adults (OA) can interfere in their reporting their diet. Objective: to evaluate the impact of memory bias in dietary estimation between OA and their primary caregivers (PC) through the food frequency questionnaire (FFQ) for Mexican OA and weighed food records (WFR). Methods: the present analysis uses the estimated dietary information based on the response provided by 51 older adults (OA) and their primary caregivers (PC) from the validation study of the FFQ for Mexicans OA was conducted during lockdowns for COVID-19.
