AI Article Synopsis
- The system-bath entanglement theorem (SBET) connects the properties of an entangled system and its environment to individual system and bath attributes, initially established through linear response and correlation functions.
- The current work expands the SBET to include field-dressed scenarios with several baths at varying temperatures, acknowledging that external fields interact not just with the system but also with its environment.
- This extension of SBET can enhance research in areas like photo-acoustic, photo-thermal, and pump-probe studies, while also addressing field-free conditions and classical equivalents of the theorem.
Article Abstract
The system-bath entanglement theorem (SBET) was established in terms of linear response functions [Du et al., J. Chem. Phys. 152, 034102 (2020)] and generalized to correlation functions [Su et al., J. Chem. Phys. 160, 084104 (2024)] in our previous studies. This theorem connects the entangled system-bath properties to the local system and bare-bath ones. In this work, we extend the SBET to field-dressed conditions with multiple baths at different temperatures. As in reality, the external fields may interact with not only the system but also environments. The extended SBET facilitates, for example, photo-acoustic, photo-thermal, pump-probe related studies. The theorem under the field-free condition (multiple baths) and its counterpart in the classical limit is also presented.

A systematic review of psychometric properties of questionnaires assessing activities of daily living among older adults with neurocognitive disorders.
Aust Occup Ther J
February 2025
School of Physical and Occupational Therapy, Faculty of Medicine, McGill University, Montreal, Quebec, Canada.
Introduction: Mild cognitive impairment (MCI) and Alzheimer's disease (AD) lead to decline in performance in activities of daily living (ADLs). Multiple questionnaires assess this construct among older adults. The objective of this study was to review existing literature studying psychometric properties of questionnaires assessing performance in ADLs of older adults living with MCI and AD specifically.

Objectives: The aim of the present study was to investigate, whether polyetherketoneketone (PEKK) secondary crowns could be considered as alternative to gold standard in terms of their physical properties and manufacturing costs.
Methods: An upper jaw model with six implants was used. Frameworks with either 6 PEKK- or 6 electroplated secondary crowns were cemented in a wear simulator.

Background And Aims: The purpose of this study was to examine the associations of basic activities of daily living (BADL) and its longitudinal changes with cardiovascular disease (CVD) risk among older population.
Methods And Results: We conducted a prospective analysis of the Chinese Longitudinal Healthy Longevity Survey between 2008 and 2018 in 7051 participants aged 65 years or over. Cox proportional hazards models were performed to evaluate the associations of baseline and longitudinal changes in BADL with the incidence of CVD.
Exploring the 'EarSwitch' concept: a novel ear based control method for assistive technology.

Background: Loss of communication with loved ones and carers is one of the most isolating and debilitating effects of many neurological disorders. Assistive technology (AT) supports individuals with communication, but the acceptability of AT solutions is highly variable. In this paper a novel ear based control method of AT, the concept of 'EarSwitch', is presented.

To assess the sources, levels, spatial distributions and exposure to human health, the concentration of heavy metals Pb, Cu, Mn, Zn, and Fe in the sand/sediment of the Parki Beach area of Anowara, Chattogram, Bangladesh are determined using Atomic Absorption Spectroscopy (AAS) for the first time. A total of 40 surface and subsurface sand and sediment samples were collected from 20 different sampling points along the 15 km long Parki Beach area, Bangladesh. Average concentrations of Pb, Cu, Mn, Zn and Fe in surface samples are 14.
