Parametric nonlinear optical processes are instrumental in optical quantum technology for generating entangled light. However, the range of materials conventionally used for producing entangled photons is limited. Metal-organic frameworks (MOFs) have emerged as a novel class of optical materials with customizable nonlinear properties and proven chemical and optical stability.

The consequences of heat stress during the dry period can extend into the postpartum period, affecting health and productivity in the subsequent lactation. We hypothesized that cows with distinct core body temperatures (CBTs) would exhibit disparate behaviors associated with different degrees of heat generation or dissipation. The primary objective was to investigate behavioral differences of dry Holstein cows ( = 50) classified as high-temperature (HT) or low-temperature (LT), based on median CBT during the summer months using visual observations and accelerometer technology.

Tripodal ligands that can encapsulate single or multiple metal sites in -symmetric geometric configurations constitute valuable targets for novel catalysts. Of particular interest in ligand development are efforts toward incorporating apical elements that exhibit little if any electron donicity, to enhance the electrophilic nature of a positioned active oxidant (, metal-oxo, -nitrene). The tripodal ligand TMGtrphen-Arene has been synthesized, featuring an arene platform 1,3,5-substituted with phenylene arms possessing tetramethylguanidinyl (TMG) residues.

Article Synopsis
  • The study aimed to investigate how body composition changes after tonsillectomy and the effects of branched-chain amino acids (BCAAs) on these changes.
  • It involved 48 patients who were split into control and experimental groups, with the experimental group taking BCAAs daily, and body composition measured before and after surgery.
  • Results showed that while both groups lost weight, the BCAA group maintained or even increased muscle mass and improved body fat percentage, suggesting BCAA could help offset negative body composition effects of tonsillectomy.

Background: The population of older adults worldwide continues to increase, placing higher demands on primary health care and long-term care. The costs of housing older people in care facilities have economic and societal impacts that are unsustainable without innovative solutions. Many older people wish to remain independent in their homes and age in place.
