This study incorporated nanomaterials to modify traditional sea sand mortar to enhance the durability of marine infrastructure. It explored the effects of nano-silica (NS), nano-metakaolin (NMK), and nano-alumina (NA)) on the chloride binding capacity and microstructure of the sea sand mortar throug...

IntroductionSepsis, particularly sepsis-induced liver injury (SLI), exhibits acute onset and high mortality (up to 80%). While murine models are widely used for mechanistic studies due to limited human sample availability, their accuracy in replicating human SLI pathophysiology remains debated. Meth...

BackgroundIschemic heart disease (IHD) is one of the leading causes of mortality and disability among the older adults. Studies have shown that air pollution (AP) exacerbates the risk of cardiovascular diseases, particularly IHD, posing significant health threats to older adults and increasing disea...

Abstract: Genetic and metabolic engineering approaches are powerful tools for improving the tolerance of maize to abiotic stresses because they are faster and can afford greater control over agronomically useful traits. However, in-depth understanding of the molecular mechanisms controlling response...

We present a design method for a directional coupler-type polarization beam splitter (PBS) for ultrabroadband operation based on a genetic algorithm (GA). The PBS is discretized into short sections, with the geometric parameters of each section optimized using a GA. For PBSs with an operating wavele...

The downwelling light sensor (DLS) is the industry-standard solution for generating UAV-based digital orthophoto maps (DOMs). Current mainstream DLS correction methods primarily rely on angle compensation. However, due to the temporal mismatch between the DLS sampling intervals and the exposure time...

Task switching is a common method to investigate executive functions such as working memory and attention. This paper investigates the effect of acute stress on brain activity using task switching. Surprisingly few studies have been conducted in this area. There is behavioral and physiological evide...
