Local structure, electronic and optical characteristics of Er-doped YScAlOgarnet: a multi-scale exploration based on first-principles.

In this study, the structural evolution, electronic properties, and optical characteristics of Er-doped YScAlO(YSAG) crystals were systematically investigated by the CALYPSO structure prediction methodology combined with density functional theory. The crucial findings are detailed as follows. (1) The ground state structure of Er:YSAG was determined.

Association between triglyceride-glucose index and femoral bone mineral density in community-dwelling, nondiabetic men and women: a NHANES analysis of 1,928 US individuals.

Objective: To determine the potential association between the triglyceride-glucose (TyG) index and bone mineral density (BMD) in community-dwelling adults without diabetes using a nationally representative database from the United States (US).

Methods: Data were extracted from the National Health and Nutrition Examination Survey (NHANES) 2005-2010, 2013-2014, and 2017-2018. Men and postmenopausal women aged ≥50 years with complete data on femoral neck BMD, triglycerides, and fasting plasma glucose levels were eligible for inclusion.

Risk Perception and Public Pandemic Fatigue: The Role of Perceived Stress and Preventive Coping.

Purpose: This study explores the status of pandemic fatigue, predictors, and their mechanisms of action based on a stress-response framework and a parallel model of future-oriented response.

Patients And Methods: Study 1 investigated 8426 Chinese adult residents' understanding of and willingness to cooperate with the pandemic prevention and control policies and Study 2 surveyed 1635 Chinese residents on their activeness of pandemic prevention and control (APPC), pandemic risk perception, perceived stress, and future-oriented coping.

Results: Study 1 found that public understanding of and willingness to cooperate with prevention policies were significantly lower in 2022 than in 2020 and 2021.

Propionate poses antivirulence activity against Botrytis cinerea via regulating its metabolism, infection cushion development and overall pathogenic factors.

Botrytis cinerea is a devastating pathogen causing gray mold in fruits and vegetables if not properly managed. Although the mechanisms remain unclear, we previously revealed that the safe food additive calcium propionate (CP) could suppress gray mold development on grapes. The present study reports that sub-lethal dose of CP (0.

Associations between bone-alkaline phosphatase and bone mineral density in adults with and without diabetes.

Insufficient evidence is available to reliably compare the roles of bone alkaline phosphatase (BAP) and bone mineral density (BMD) in diabetes. This study aimed to compare associations between BAP and BMD in adults with and without diabetes to elucidate fracture risk in diabetes.Data were extracted from the National Health and Nutrition Examination Survey (NHANES), 2001-2004, including 4197 adults aged 20 to 49 years, 143 with diabetes (DM group), and 4054 without (non-DM group).

Impact of diabetes on the prognosis of hip fracture: a cohort study in the Chinese population.

Background: Diabetes has been associated with increased risk of fracture and impaired fracture healing. The aim of this study was to examine the influence of diabetes on perioperative complications, length of stay and ambulatory ability recovery in individuals with hip fracture, and to determine whether changes could be made to improve treatment outcome.

Methods: The study included 707 hip fracture patients treated at Beijing Jishuitan Hospital between July 2009 and December 2010.

Prevalence of Osteoporosis and Its Associated Factors among Older Men with Type 2 Diabetes.

This study investigated the prevalence of osteoporosis and its associated factors in old men with T2DM to identify risk factors for low BMD. We enrolled 93 old men (≥60 years of age) with T2DM and 125 healthy old men (controls) and collected data of their lifestyle, medical history, bone densitometry, body weight, height, and blood pressure. Blood samples were collected for biochemical analyses.

Theoretical study of EPR spectra for Mn2+ ion in [Mg(H2O)6]SnCl6 single crystal.

The relationship between the impurity structures and the electron paramagnetic resonance (EPR) parameters D, (a-F) have been studied by diagonalizing the complete energy matrices for Mn2+ ion in [Mg(H2O)6]SnCl6 single crystal in a trigonal ligand field within a weak-field-representation. It is shown that the local lattice structure around Mn2+ ion in [Mg(H2O)6]SnCl6 exhibits an elongation distortion which is different at 290 K and 77 K. The local structure parameters R=2.
