The impact of physical activity on subjective wellbeing in college students: the chain-mediating role of rumination and mindfulness.

Background: Subjective wellbeing (SWB) is an important indicator of mental health, and physical activity (PA) has been shown to have a positive impact on SWB. However, the specific pathways through which PA enhances SWB via psychological mechanisms remain unclear. Cognitive regulation theory suggests that emotional experiences are influenced by cognitive processes, where rumination (RT) and mindfulness (MDS) play key roles in regulating emotional states.

Ultrafast charging of two-dimensional polymer cathodes enabled by cross-flow structure design.

While ultrafast charging and discharging is highly desired for energy storage, the densely packed crystalline inorganic electrodes suffer from sluggish ion transport that limits this capability. Here we report two-dimensional vertical ladder polymer cathode materials that feature layered nanosheets with rich intralayer pores and structural defects alongside weak interlayer interactions. This structural design allows lithium ions to migrate vertically across the intrinsic pores and/or defects accompanied by horizontal intercalation, thus establishing a cross-flow pathway for lithium storage.

Self-Supervised Visual Tracking via Image Synthesis and Domain Adversarial Learning.

With the widespread use of sensors in applications such as autonomous driving and intelligent security, stable and efficient target tracking from diverse sensor data has become increasingly important.

Supramolecularly Confined Catalysis in Polyphthalocyanine-Crown-Ether Frameworks Boosts Sulfur Redox Kinetics.

Metal phthalocyanines are considered as potent catalysts in lithium-sulfur (Li-S) chemistry. However, their adsorption capability is deficient to inhibit polysulfides from shuttling, which in turn retards the S-redox reaction in the cathode. Here we report flexible, two-dimensional (2D) polyphthalocyanine-crown-ether (PPc-CE) frameworks that provide a supramolecularly confined space created with the single-atom catalytic nickel phthalocyanine nodes and crown-ether linkers as Li host.

G3BP1 Regulates the Cell Cycle by Promoting IFNβ Production to Promote PCV2 Replication and Promotes Nuclear Transfer of Viral Proteins by Direct Binding.

Porcine circovirus type 2 (PCV2) is a significant pathogen responsible for porcine circovirus-associated diseases (PCVAD), and it is widely prevalent in pig farms, leading to huge economic losses for the pig industry. Currently, the ability of PCV2 to enhance its own replication by using the antiviral inflammatory factors IFNα, IFNβ, and IL-2 and its complex immune escape mechanism remain unclear, which has attracted wide attention. Research has indicated that GTPase-activating protein (SH3 domain)-binding protein 1 (G3BP1) is involved in the innate immune response to a variety of viruses, primarily by regulating and composing stress granules (SGs) to inhibit viral replication.
