Online learning has accentuated the role and interaction of numerous educational and psychological factors among students, especially undergraduates. Psychological resilience, as an evaluative factor of mental health, has been confirmed in previous studies as having an effect on undergraduates' online learning performance and satisfaction. However, the mediating mechanisms should be further explored to fully understand the relationship between psychological resilience and online learning performance, as well as between psychological resilience and online learning satisfaction. To fill this gap, this study proposed a mediation model which included academic burnout as the mediating variable to clarify the relationships among psychological resilience, online learning performance and satisfaction. A total of 807 Chinese undergraduates with long-term experience of online learning voluntarily participated in this study. They completed the self-report measures of psychological resilience, online learning performance and satisfaction, as well as academic burnout. Results showed that in online learning, undergraduates' psychological resilience was negatively related to their academic burnout, psychological resilience was positively related to online learning performance and satisfaction, academic burnout was negatively related to online learning performance and satisfaction, and academic burnout mediated the effect of psychological resilience on online learning performance and satisfaction. The findings of this analysis offer practical guidance implications for undergraduates to improve their online learning, and provide theoretical support for instructors to focus on undergraduates' psychological status.

The characteristics of surface functional groups, lattice structure, and nuclear chemical shift of coal gangue under mechanical force were analyzed. The mechanical activation mechanism of coal gangue was explored from the molecular structure level. The results indicated that the main components of coal gangue were Si-O and Al-O. The Si-O was relatively stable, and mechanical force could destroy the [SiO4](4-) tetrahedral structure to a certain extent, increasing the amorphous Si-O structure. The existing forms of Al-O mainly included four- and six-coordinate polyhedral structures, and the former's stability was significantly more robust than that of the latter. In the ultrafine grinding process, the Al-OH group on the inner surface of the coal gangue and the hydroxyl group inside the Al-O octahedron was destroyed, and the Al-O six-coordinate structure gradually disappeared. It was considered that Al3+ ions in coal gangue enter the three-dimensional structure based on [SiO4](4-) tetrahedron to form a more stable [AlO4](5-) tetrahedron and other Al3+ ions outside the network existed in the form of [AlO6](9-) octahedron, which was more easily activated. With the activation effect of mechanical force in the grinding process, the extraction rate of aluminum increased from 7.24 to 62.33%, which also confirmed the above analysis conclusions.

Utilizing the Matlab platform, two-dimensional diffusion-limited aggregation and three-dimensional diffusion-limited cluster aggregation models were established to simulate the hydrophobic flocculation of coal particles. The formation process of flocs aggregated by monomer particles and small groups was simulated from both plane and space perspectives. The gyration radius fractal dimension increased from 1.401 to 1.539 in the DLA model and from 1.623 to 1.729 in the DLCA model, indicating that the floc morphology gradually stabilized and the structure became increasingly regular during the hydrophobic flocculation process. The porosity of DLA increased from 0.762 to 0.851, indicating that the dendritic structure of flocs formed a spatial shielding effect on the planar structure, which prevented the particles from entering the flocs. In contrast, the porosity of DLCA first increased from 0.506 to 0.611 and then decreased, stabilizing at approximately 0.53, indicating that small groups filled the internal voids of flocs in the spatial structure, leading to a gradual increase in floc density. The surface fractal dimension and density of flocs were calculated using the surface fractal and hydrostatic sedimentation-terminal velocity theories, respectively, confirming the conclusions drawn from the simulation analysis.

Bacillus thuringiensis (Bt) is widely used as a biopesticide worldwide. To date, at least eight pest species have been found to be resistant to Bt in the field. As the first pest that was reported having resistance to Bt in the field, considerable research has been done on the mechanisms of Bt resistance in Plutella xylostella. However, whether the acquisition of Bt resistance by P. xylostella comes at a fitness cost is also a valuable question. In this study, Aminopeptidase-N 2 (APN2), a Cry toxin receptor gene of P. xylostella, was knocked down by RNA interference, resulting in improved resistance to Cry1Ac. It was also found that larval mortality of APN2 knockdown P. xylostella was significantly higher than that of the control, while the pupation rate, pupal weight, eclosion rate, fecundity (egg/female), hatchability, and female adult longevity were significantly lower in APN2 knockdown P. xylostella than in the control. These results illustrate that if Cry1Ac resistance was obtained only through the reduction of APN2 expression, P. xylostella would need to incur some fitness costs for it.

Background Circadian disruptions are increasingly recognized in Alzheimer's disease (AD) patients and may influence disease onset and progression. This study examines how AD pathology affects blood-borne factors that regulate circadian rhythms. Methods Eighty-five participants from the Sino Longitudinal Study on Cognitive Decline were enrolled: 35 amyloid-beta negative normal controls (A beta- NCs), 23 amyloid-beta positive normal controls (A beta+ NCs), 15 patients with amnestic mild cognitive impairment (aMCI), and 12 with Alzheimer's disease dementia (ADD). Patients with aMCI and ADD were grouped as cognitively impaired (CI). Cellular circadian period length was assessed using a serum-based assay. Expression levels of clock genes in serum-treated cells and in leukocytes of participants were measured via real-time PCR. Plasma biomarkers were quantified using a single-molecule array immunoassay. Pineal parenchymal and hippocampal volumes were determined by magnetic resonance imaging. Results The cellular circadian period length was significantly extended by serum from CI patients than by that from A beta- NCs (p < 0.01). Treatment of cells with serum from the CI patients resulted in suppressed expression of the clock genes Bmal1 and Nr1d1. Strong relationships between the expression levels of clock genes observed in leukocytes of the A beta- NC group did not appear in those of the A beta+ NC or CI groups. The significant correlation of cellular circadian period length and the pineal volume was only observed in the A beta- NC group, but not in the A beta+ NC or CI groups. Conclusions This study indicates the presence of significant changes in blood-borne factors that could affect the circadian rhythms in AD, starting even at preclinical stages. These alterations could precede cognitive decline and contribute to AD pathogenesis. Trial registrationThe cohort is registered at *** (SILCODE: NCT03370744;Registered on Mar 15th, 2017).

Traditional vanadium dioxide (VO2) material faced severe challenges of low stability in acid, humid, and oxygenic environments, which hinder its real applications. Here, we report a facile improving process which can enhanced the stability of VO2 nanocrystals in the environments above. Ascorbic acid (AA), as an important antioxidant for organism in medicine and biology, was ingeniously used for enhancing the antioxidation abilities of inorganic material. At the same time, the AA could generate the hydrogen doping occurred on the surface of VO2 nanocrystals, which enhanced their Antiacid abilities simultaneously. The AA treated VO2 nanocrystals retain stable in H2SO4 and H2O2 solution and exhibit high durability in hyperthermal (60 degrees C) and humid (90%) environment. Characterizations and first-principles theoretical calculations confirmed that the coordination of ascorbic acid molecules on VO2 nanocrystals induced charge-carrier density reorganization and protons transferring electrostatically. Then the formed HxVO2 provides an enhancing formation energy for oxygen vacancy and protects the particles from corrosion. This work is beneficial to the VO2 nanoparticles coated and decorated processes and exhibit good potential for practical application of VO2-based smart windows.

The androgen receptor (AR) is a critical therapeutic target for the endocrine treatment of prostate cancer (PCa). Current AR antagonists, which primarily target the hormone binding pocket (HBP) within the ligand-binding domain (LBD), are often limited by the emergence of resistance mutations, calling for novel strategies of AR inhibition. In this study, a series of substituted benzene sulfonamide derivatives were designed and synthesized based on IMB-A6, a lead compound previously identified by our group to target the activation function 2 (AF2) region of AR-LBD. These compounds were evaluated for AR inhibitory activity using a dual-luciferase reporter assay, with selected derivatives further assessed for their anti-proliferative effects against the LNCaP cell line. Notably, compounds 8a and 3l also exhibited significant inhibitory activity against the AR F876L mutant. Additionally, the pharmacokinetic (PK) profile of 8a was evaluated in male Sprague-Dawley (SD) rats. In vivo studies using the LNCaP xenograft model revealed that oral administration of 8a (30 mg/kg, BID) effectively suppressed tumor growth with tumor growth inhibition (TGI) rate of 48.20 %. Molecular docking studies of 8a binding to the AF2 region were conducted. 8a represents the first reported example of an orally effective AR inhibitor derived from AF2-targeting research, offering a promising therapeutic strategy to overcome resistance mutations in PCa treatment. © 2025 Elsevier Masson SAS

Strong coupling in photonic microstructures attracts broad attention due to its promising applications in spectral control, optical sensing, and light-matter interactions. Herein, we demonstrate the coupling effect in the photonic multilayer with a planar nanocavity on a one-dimensional (1D) photonic crystal (PC). The experiment results show that the spectral profile of the coupling effect can be effectively controlled by adjusting the thickness of the dielectric layer in the nanocavity, which is in good accordance with the calculations. The coupled-oscillator theoretical analysis reveals that the coupling response exhibits a Rabi splitting of 36 meV with a distinct anticrossing behavior, which stems from the strong coupling interaction between the nanocavity resonance and Tamm plasmons (TPs) between the metallic film and PC. The coupling strength can be effectively tuned by adjusting the thickness of the metallic film on the PC. We find that the coupling between the cavity and TP modes locates in the strong coupling regime when the metallic film thickness is less than 36 nm. This work will offer a new pathway for realizing optical coupling and spectral control in photonic microstructures.

This study focused on exploring the impact of different konjac glucomannan (KGM) contents (0, 1, 3, 5 g/100 g) on fibrous structure formation in walnut protein and wheat gluten high-moisture meat analogues (HMMAs). The results showed that KGM enhanced hardness, chewiness, springiness and fibrous degree of high-moisture meat analogues. KGM was observed to modify fibrous structure formation and orientation in HMMAs. Comprehensive analysis of the effect of KGM on the quality and microstructure of HMMAs revealed that when the addition content of KGM was 3 g/100 g, HMMAs had the highest fibrous degree, and the fibrous structure displayed strong toughness, and formed a more consistent, continuous and dense structure. Consequently, HMMAs with 3 g/100 g KGM was chosen for study the mechanism of KGM controlling fibrous structure formation in HMMAs during the high-moisture extrusion process. 3 g/100 g KGM improved HMMAs' thermal stability and apparent viscosity. 3 g/100 g KGM promoted more covalent and non-covalent bonds formation, thereby improving the cross-linking degree of protein molecules. 3 g/100 g KGM promoted natural protein disintegration from high-to low-molecular-weight forms, mainly with protein subunits 30-40 kDa. In addition, 3 g/100 g KGM enhanced protein structure orderliness. This study offers valuable information for developing plant-based protein meat analogues that have rich fibrous structures through the addition of exogenous polysaccharides.
