Cumulative ecological risk and problematic smartphone use among Chinese college students: the roles of performance goal orientation, learning goal orientation and psychological resilience.

Problematic smartphone use (PSU) has emerged as a pressing concern among college students, with cumulative ecological risk identified as a crucial yet enigmatic contributor. To unravel its underlying mechanisms, we devised and validated a model that delves into the mediating roles of performance and learning goal orientations, as well as the moderating influence of psychological resilience. Our investigation encompassed 2011 Chinese college students spanning from freshmen to seniors, aged 16 to 25, utilizing comprehensive scales to assess various constructs.

Spatial correlation of desorption events accelerates water exchange dynamics at Pt/water interfaces.

The altered solvation structures and dynamical properties of water molecules at the metal/water interfaces will affect the elementary step of an electrochemical process. Simulating the interfacial structure and dynamics with a realistic representation will provide us with a solid foundation to make a connection with experimental studies. To surmount the accuracy-efficiency tradeoff and provide dynamical insights, we use state-of-the-art machine learning molecular dynamics (MLMD) to study the water exchange dynamics, which are fundamental to adsorption/desorption and electrochemical reaction steps.

capsular polysaccharide A ameliorates ulcerative colitis in rat by recovering intestinal barrier integrity and restoring gut microbiota.

() is a Gram-negative, obligate anaerobic, commensal bacterium residing in the human gut and holds therapeutic potential for ulcerative colitis (UC). Previous studies have indicated that capsular polysaccharide A (PSA) of is a crucial component for its effectiveness, possessing various biological activities such as anti-inflammatory, anti-tumor, and immune-modulating effects. We previously isolated and characterized the strain ZY-312 from the feces of a healthy breastfed infant, and extracted its PSA, named TP2.

Study of the Drug Resistance Function of Ivermectin-Resistance-Related miRNAs in Haemonchus contortus.

Haemonchus contortus has caused significant economic losses in many regions. The emergence of drug resistance has created new difficulties for the prevention and control of parasitic diseases in cattle and sheep. The mechanism of drug resistance to ivermectin in H.

AIE-active Circularly Polarized Thermally Activated Delayed Fluorescence Emitters for Stable Solution-Processed Circularly Polarized Electroluminescence.

Circularly polarized organic light-emitting diodes (CP-OLEDs) have significant promise for naked-eye 3D displays. However, most devices are fabricated using vacuum deposition technology, and development of efficient solution-processed CP-OLEDs, particularly those exhibiting low efficiency roll-off, remains a formidable challenge. This research successfully designed and synthesized two pairs of thermally activated delayed fluorescence (TADF) enantiomers through isomer engineering, namely (R/S)-N-5-TPA and (R/S)-N-4-TPA, which features fifth and fourth substitution sites of phthalimide (acceptor) by tri-phenylamine (donor), respectively.
