A modified damaged stress model for fatigue life prediction based on load interaction.

This study proposes a modified Damage Stress Model (DSM) for fatigue life prediction, addressing the variability of ultimate stress during damage transfer under multi-stage stress. The model incorporates Generalized Ultimate Stress (GUS), influenced by the ultimate stress, the sum of the previous-stage fatigue damage, and the ratio of adjacent stress. Comparative analysis with the Miner, DSM, and Manson models, using experimental data from multiple materials and stages, shows that the proposed model outperforms others, rectifying limitations of the original DSM and providing more accurate fatigue predictions.

Antimicrobial Biphasic Polymer Coatings Enabled by Fast Diffusion of Active Compounds.

The recent COVID-19 pandemic and the prospect of future global pandemics highlight the long-standing need to passively eliminate viruses and bacteria on surfaces. Conventional antimicrobial surfaces and coatings are typically constrained by a trade-off between antimicrobial efficacy and physical durability. A biphasic polyurethane coating has been developed that breaks this trade-off by incorporating a durability-imparting polycarbonate (PC) discrete phase with a continuous poly(ethylene glycol) (PEG) transport phase that absorbs, stores, and releases antimicrobial active compounds for extended microbial inactivation.

2-dodecyl-6-methoxycyclohexa-2,5-diene-1,4-dione mediates the effect of ROS-enhanced PI3K/Akt/mTOR pathway on autophagy in breast cancer.

Several studies have suggested a potential antitumor effect of 2-dodecyl-6-methoxycyclohexa-2,5-diene-1,4-dione (DMDD). To further understand the mechanism of action of this compound, we investigated its effect on the phosphatidylinositol-3-kinase (PI3K)/serine-threonine kinase (Akt)/mammalian target of rapamycin (mTOR) signaling pathway. We show that DMDD application significantly inhibited the proliferation of breast cancer cell lines MDA-MB-231 and ER-α positive MCF-7.

Background: The association between heatwave and heat-related outcomes in people with mental health conditions with and without psychotropics was unclear.

Methods: We identified people with severe mental illness (SMI) and depression, respectively, using Japanese claim data of Ibaraki prefecture during 1/1/2014-31/12/2021. We conducted self-controlled case series to estimate the incidence rate ratio (IRR) of heat-related illness, myocardial infarction and delirium, respectively, during 5-day pre-heatwave, heatwave, and 5-day post-heatwave periods all other periods (baseline) within an individual, stratified by periods prescribed psychotropics and periods not prescribed psychotropics, respectively.

Overexpression of ace2 compensating for the acetylcholinesterase activity loss from ace1 mutations accelerated the development of eggs and early nymphs in Nilaparvata lugens.

Acetylcholinesterase (AChE) guarantees the acetylcholine signal in insect central nervous system, and is the target of organophosphorus and carbamate insecticides, towards which resistance was often reported due to AChE mutations. In Nilaparvata lugens, a major pest on rice, two mutations (G119S and F331C) were detected in AChE1 in a chlorpyrifos-resistant (CHL) strain. The double mutations in AChE1 reduced total AChE activity in metabolizing acetylcholine, such as low protein stability, substrate affinity and catalytic efficiency, which needed compensation in a special way.

Endothelium-derived 6-nitrodopamine is the major mechanism by which nitric oxide relaxes the rabbit isolated aorta.

6-Nitrodopamine (6-ND) is the predominant catecholamine released from isolated vascular tissues in both mammals and reptiles, with its release being significantly reduced by the NO synthesis inhibitor, N-nitro-L-arginine methyl ester (L-NAME). The vasorelaxation induced by 6-ND is unaffected by either L-NAME or the soluble guanylate cyclase (sGC) inhibitor, ODQ, indicating an alternative mechanism of action. The vasorelaxant effect appears to be mediated through selective antagonism of dopamine D receptors rather than traditional nitric oxide (NO)-mediated pathways.

Second harmonic generation and broad-band photoluminescence in mesoporous Si/SiO nanoparticles.

Efficient second harmonic generation and broad-band photoluminescence from deeply subwavelength and nontoxic nanoparticles is essential for nanophotonic applications. Here, we explore nonlinear optical response from mesoporous Si/SiO, SiO, and Si nanoparticles, considering various fabrication and treatment procedures. We show that thermal annealing (including femtosecond laser treatment) of mesoporous Si/SiO nanoparticles provides the transformation of Si phase from amorphous to crystalline, enhancing the second harmonic and nonlinear photoluminescent response.

Tailoring of the polarization-resolved second harmonic generation in two-dimensional semiconductors.

Second harmonic generation is a non-linear optical phenomenon in which coherent radiation with frequency interacts with a non-centrosymmetric material and produces coherent radiation at frequency 2. Owing to the exciting physical phenomena that take place during the non-linear optical excitation at the nanoscale, there is currently extensive research in the non-linear optical responses of nanomaterials, particularly in low-dimensional materials. Here, we review recent advancements in the polarization-resolved second harmonic generation propertied from atomically thin two-dimensional (2D) crystals and present a unified theoretical framework to account for their nonlinear optical response.

Photo-thermo-optical modulation of Raman scattering from Mie-resonant silicon nanostructures.

Raman scattering is sensitive to local temperature and thus offers a convenient tool for non-contact and non-destructive optical thermometry at the nanoscale. In turn, all-dielectric nanostructures, such as silicon particles, exhibit strongly enhanced photothermal heating due to Mie resonances, which leads to the strong modulation of elastic Rayleigh scattering intensity through subsequent thermo-optical effects. However, the influence of the complex photo-thermo-optical effect on inelastic Raman scattering has yet to be explored for resonant dielectric nanostructures.
