Article Abstract
A general comment is made on the existence of various baths in quantum thermodynamics, and a brief explanation is presented about the concept of weak invariants. Then, the isoenergetic process is studied for a spin in a magnetic field that slowly varies in time. In the Markovian approximation, the corresponding Lindbladian operators are constructed without recourse to detailed information about the coupling of the subsystem with the environment called the energy bath. The entropy production rate under the resulting Lindblad equation is shown to be positive. The leading-order expressions of the power output and work done along the isoenergetic process are obtained.

Effect of high intakes of protein-only and carbohydrate-only on plasma metabolites and hormones, in addition to nitrogen excretion.

Background: Hormonal and metabolic responses to high protein intake are not well understood. The aims of this study were to compare the metabolic and hormonal responses to isocaloric intakes of whey protein alone versus carbohydrate alone. Additionally, we measured urinary nitrogen excretion as a marker of protein degradation.

Background: Meat and dairy substitutes are gaining popularity, but their expected overall impact on health remains unclear.
Objectives: We aimed to simulate the complete substitution of meat, milk, and dairy desserts with plant-based substitutes (PBSs) to assess the impact on nutrient deficiency risk and chronic disease-related mortality.
Methods: Using individual baseline dietary data from adults in the latest French national survey (N = 2121; INCA3), we simulated isoenergetic diets where all meat, milk, and dairy desserts were replaced by an equivalent amount of PBSs.
Association Between Psychobehavioral Factors and the Increased Eating Rate of Ultra-Processed Versus Non-Ultra-Processed Meals in Individuals with Obesity: A Secondary Analysis of a Randomized Trial.

: A faster eating rate is associated with increased energy intake and risk of obesity. High consumption of ultra-processed foods (UPFs) is associated with a faster eating rate. Psychobehavioral aspects, such as body image self-perception, eating disorders, and anxiety, may modulate this eating behavior.

In photoactive metal complexes the localization of photoexcited charges dictates the site of chemical reactivity, but few studies measure the charge redistribution in these systems with spatial precision. Herein, we track the inter- and intra-ligand charge transfer processes that underpin light-driven charge separation in the well-studied "molecular lightswitch" [Ru(bpy)dppz] (aqueous [Ruthenium(2,2'-bipyridine)2(dipyrido[3,2-a:2',3'-c]phenazine)][Cl]) by probing the electronic structure of ligand nitrogen atoms in real-time using ultrafast X-ray absorption spectroscopy and first principles calculations. We confirm the localization of excited electron density on the phenazine N atoms of dppz and we newly identify two parallel electron transfer pathways to populate this state.

Background: Although food-based dietary guidelines (FBDG) include guidelines for meat consumption, they most often do not explicitly include environmental considerations. For instance, in France, FBDG recommend consuming no more than 500 g of red meat and 150 g of processed meat per week. This study uses modeling to investigate the range of greenhouse gas emissions (GHGe) that can be achieved under FBDG compliance.
