Identification of genetic variants of the gene in association with COPD susceptibility.

Background: Although existing studies have identified some genetic loci associated with chronic obstructive pulmonary disease (COPD) susceptibility, many variants remain to be discovered. The aim of this study was to further explore the potential relationship between single nucleotide polymorphisms (SNPs) and COPD risk.

Methods: Nine hundred and ninety-six subjects were recruited (498 COPD cases and 498 healthy controls).

Multifunctional Artificial Electric Synapse of MoSe-Based Memristor toward Neuromorphic Application.

Research on memristive devices to seamlessly integrate and replicate the dynamic behaviors of biological synapses will illuminate the mechanisms underlying parallel processing and information storage in the human brain, thereby affording novel insights for the advancement of artificial intelligence. Here, an artificial electric synapse is demonstrated on a one-step Mo-selenized MoSe memristor, having not only long-term stable resistive switching characteristics (reset 0.51 ± 0.

Bimetallic metal-organic frameworks as electrode modifiers for enhanced electrochemical sensing of chloramphenicol.

An electrochemical sensor is presented for the detection of the chloramphenicol (CAP) based on a bimetallic MIL-101(Fe/Co) MOF electrocatalyst. The MIL-101(Fe/Co) was prepared by utilizing mixed-valence Fe (III) and Co (II) as metal nodes and terephthalic acid as ligands with a simple hydrothermal method and characterized by SEM, TEM, XRD, FTIR, and XPS. Electrochemical measurements such as electrochemical impedance spectroscopy (EIS), cyclic voltammetry (CV), and differential pulse voltammetry (DPV) showed that bimetallic MIL-101(Fe/Co) had the faster electron transfer, larger electroactive area, and higher electrocatalytic activity compared with  their monometallic counterparts due to the strong synergistic effect between bimetals.

How to correct Ehrenfest nonadiabatic dynamics in open quantum systems: Ehrenfest plus random force (E + σ) dynamics.

One key challenge in the study of nonadiabatic dynamics in open quantum systems is to balance computational efficiency and accuracy. Although Ehrenfest dynamics (ED) is computationally efficient and well-suited for large complex systems, ED often yields inaccurate results. To address these limitations, we improve the accuracy of the traditional ED by adding a random force (E + σ).

Innovative Application of Electrokinetic Treatment on Montmorillonite Modification: Effects on pH, Current, and Swelling Properties of Ca-Montmorillonite.

This study evaluates the feasibility of converting Ca-montmorillonite into Na-montmorillonite through electroosmosis. Comprehensive analyses of current, pH, ζ-potential, and ethylene glycol expansion were conducted to investigate the macro- and microscale effects of electroosmosis. The results demonstrate that electroosmosis effectively reduces the swelling properties of montmorillonite.
