The snowmelt process is becoming more complex in the context of global warming, and the current existing studies are not effective in using the short-term prediction model to drive the distributed hydrological model to predict snowmelt floods. In thi

To further understand a muzzle combustion mechanism in high-altitude firing, the influence of supersonic flow on a muzzle combustion phenomenon is investigated. The set of internal ballistic equations is employed, providing accurate velocity and pres

Migrant seasonal workers manually harvest apples throughout the U.S. using ladders and buckets due to the care required for prevention of bruises and other physical damage. The motions associated with hand harvest have potential to cause musculoskele

Numerous studies have demonstrated that microRNAs (miRNAs) are upregulated or downregulated in retinoblastoma (RB), and that this phenomenon is associated with the modulation of various malignant behaviours during RB occurrence and development. There

Pedestrians are not constrained by road networks (for example, lanes, turn restrictions, one-way streets), unlike vehicle drivers. An optimal route for pedestrians might involve many intersections that are difficult to navigate, because they offer mo
