The theory of periodic Barlow multi-lattices (X1X2…XN)∞ with Xi ∈ {A, B, C} and Xi ≠ Xi+1 of stacked two-dimensional hexagonal close-packed layers is presented and used to derive exact lattice sum expressions in terms of fast converging Bessel function expansions for inverse power potentials. We describe in detail the mathematical properties of Barlow sphere packings and demonstrate that only two basic lattice sums are required to describe all periodic packings. For the sticky hard-sphere model with an attractive inverse power law potential, we find a linear correlation between the cohesive energies of different Barlow packings and the face-centered cubic packing fraction.

Purpose: Measures of disease burden using hospital administrative data are susceptible to over-inflation if the patient is transferred during their episode of care. We aimed to identify and compare measures of coronary heart disease (CHD) and myocardial infarction (MI) episodes using six algorithms that account for transfers.
Patient And Methods: We used person-linked hospitalisations for CHD and MI for 2000-2016 in Western Australia based on the interval between discharge and subsequent admission (date, datetime algorithms), pathway (admission source, discharge destination) and any combination to generate machine learning models (random forest [RF], gradient boosting machine [GBM]).
Since fall 2021, the authors of this study have conducted regular enumerations of the unsheltered populations in three Los Angeles neighborhoods known for having high concentrations of people experiencing unsheltered homelessness: Hollywood, Skid Row, and Venice. In addition to counts, the authors have conducted surveys of unsheltered residents in these same neighborhoods to better understand the characteristics, experiences, and needs of these populations. The results of the first year of this study, known as the Los Angeles Longitudinal Enumeration and Demographic Survey (LA LEADS), were presented in a report published by RAND in 2023.

USDA FSIS recommends meat dwell ≤6 h during cooking from 10 to 54.4°C to limit the growth of Staphylococcus aureus and prevent its production of heat-stable enterotoxins. This study evaluated the growth of S.

Cyclic diadenosine monophosphate (c-di-AMP) is a recently discovered second messenger that modulates several signal transduction pathways in bacterial and host cells. Besides the bacterial system, c-di-AMP signaling is also connected with the host cytoplasmic surveillance pathways (CSP) that induce type-I IFN responses through STING-mediated pathways. Additionally, c-di-AMP demonstrates potent adjuvant properties, particularly when administered alongside the Bacillus Calmette-Guérin (BCG) vaccine through mucosal routes.
