Department of Cardiovascular Surgery, Division of Cardiovascular Medicine, The Sixth Medical Center, Chinese PLA General Hospital, No.6 of Fucheng Road, Haidian District, Beijing, 100853, China.
Objective: This study aims to investigate the monthly variation patterns of bioelectrical impedance (BEI) along 24 meridian pathways in healthy individuals.
Methods: A cohort of 684 healthy middle-aged participants from North China was enrolled between July 1, 2017, and September 5, 2020. BEI measurements were consistently recorded along the 24 meridian pathways over the study period.
Does the digital economy enhance common prosperity? Examining the mediating influence of resilience in environmental investment.

July 2024
Faculty of Humanities and Social Sciences, Macao Polytechnic University, Macao.
Background: The link between the digital economy and prosperity is well established. However, the mechanism underlying the relationship between the digital economy and common prosperity is yet to be investigated.
Study Rationale And Purpose: The main purpose of this study is to address this mechanism by examining the extent to which the digital economy has optimized regional investments in protecting the environment, particularly the resilience of environmental investment, thus influencing common prosperity.
Non-adiabatic quantum electrodynamic effects on electron-nucleus-photon systems: Single photonic mode vs infinite photonic modes.

The quantum-electrodynamic non-adiabatic emission (QED-NAE) is a type of radiatively assisted vibronic de-excitation due to electromagnetic vacuum fluctuations on non-adiabatic processes. Building on our previous work [Tsai et al., J.

In this work, we describe a computational tool designed to determine the local dielectric constants (ε) of charge-neutral heterogeneous systems by analyzing dipole moment fluctuations from molecular dynamics (MD) trajectories. Unlike conventional methods, our tool can calculate dielectric constants for dynamically evolving selections of molecules within a defined region of space, rather than for fixed sets of molecules. We validated our approach by computing the dielectric constants of TIP3P water nanospheres, achieving results consistent with literature values for bulk water.

The mechanical coupling between molecules represents a promising route for the development of molecular machines. Constructing molecular gears requires easily rotatable and mutually interlocked pinions. Using scanning tunneling microscopy (STM), it is demonstrated that aluminum phthalocyanine (AlPc) molecules on Pb(100) exhibit these properties.
