The note updates comments written a decade and a half ago on our need for a standard schemata for comparing the living arrangements of elderly people around the world. Perforce limiting our view to populations living in private households, the note considers different schema beginning with an examination of household size and head/nonhead data and proceeding to schemes using ever more detailed data on 'relation to household head' information and data on marital status. The best scheme will of course depend on the data available and on the study's theoretical ideas, but if the ideas have to do with the nature of the family then it would seem that one is best off using a combination of information on people's relation to the household head and information on marital status to indicate family household composition. The six-category scheme (alone, spouse only, with married child[ren], with other relatives, with non-kin) might best be collapsed into a bivariate or trivariate categorical dependent variable for purposes of multivariate regression.

Chronological age is not an accurate predictor of morbidity and mortality risk, as individuals' aging processes are diverse. Phenotypic age acceleration (PhenoAgeAccel) is a validated biological age measure incorporating chronological age and biomarkers from blood samples commonly used in clinical practice that can better reflect aging-related morbidity and mortality risk. The heterogeneity of age-related decline is not random, as environmental exposures can promote or impede healthy aging.

Providing different grades of water is a promising solution to address the challenges of urban water supply, including water quality, quantity, and energy consumption. However, quantifying the effectiveness of this strategy and understanding its economic, environmental, and social impacts remain significant challenges. This study introduces a simulation-based method to predict household water use and evaluate the applicability and sustainability of the water supply system.

Although social determinants of health (SDoH) investigations have shown limited analyses of socioeconomic and race-ethnic status on certain hematologic malignancies, the impact of factors beyond those across a fuller scope of hematologic cancers remains unknown. The Social Vulnerability Index (SVI), a tool for assessing varied US-census derived sociodemographic factors, allows the specific quantification of SDoH in dynamic, regional contexts for their associations with hematologic-malignancy inequities. To assess the summative influence of varied SDoH-factors on hematologic malignancy outcomes and discern which SDoH-factors contributed the largest associations towards disparities 796,005 adults with hematologic malignancies between 1975-2017 were identified for this retrospective cohort study.

Organic-inorganic hybrid ferroelectric compounds of the halobismuthate family have emerged as a focal point of research owing to their reduced toxicity and distinctive optical characteristics. This study presents a novel ammonium hybrid perovskite, [BPMBDMA]·[Bi2Br9], which exhibits both ferro- and piezoelectric properties and crystallizes in the polar noncentrosymmetric 2 space group. The nonlinear optical (NLO) activity of [BPMBDMA]·[Bi2Br9] was corroborated through second harmonic generation measurements evidencing its noncentrosymmetric structure, which was further substantiated by piezoresponse force microscopy analyses.

In this environment, respires nitrate and increases transport and utilization of alternative carbon sources via the cAMP receptor protein (CRP), a transcription factor that is active during glucose scarcity. Here we show that nitrate respiration in aerated cultures is under control of CRP and, therefore, glucose availability.
