Article Abstract
To reduce the number of casualties in explosion accidents, blast-resistant shelters can be used to protect personnel in high-risk areas of petrochemical processing plants. In this work, the deformation behaviours of uncoated and polyurea-coated blast-resistant plates were studied through gas explosion tests. An ANSYS/LS-DYNA model of a polyurea-coated shelter was established, and the dynamic responses of the shelter under various explosion loads were analysed. A series of fuel-air explosion tests were carried out to investigate the explosion resistance of the full-scale shelter. The results showed that compared with the uncoated blast-resistant plate, the deformation of the polyurea-coated blast-resistant plate was significantly reduced. The overall deformation of the shelter was the central depression of the wall and the inward bending of the frame. The damage effect of a typical high-overpressure, low-duration load was greater than that of typical low-overpressure, long-duration load. The shelter remained intact under three repeated explosive loads, with cracks appearing on the inner wall but no collapse or debris splashing. The shock wave attenuation rate of the shelter reached over 90%, which could significantly reduce the number of indoor casualties.

Background: French Contrast Training (FCT) is a unique complex training (CT) method that has gained attention in sports science. Participant characteristics, training protocols, and control group types may influence the effects of FCT on lower limb athletic performance.
Objective: The aim of this systematic review and meta-analysis was to assess the effects of FCT on jump, sprint, and maximal strength in healthy adults and to identify potential moderators of training effects.

is an oomycete that causes late blight disease in multiple solanaceous crops, including potato and tomato. This makes it a worldwide concern for farmers, given the level of crop loss and its explosive epidemic potential. Although fungicides have traditionally been used for managing this disease, populations of resistant to fungicides have been documented.

The exceptional combination of high density and superior thermal stability renders ketone-based energetic compounds particularly attractive for heat-resistant explosives. While extensive research has demonstrated successful carbonyl functionalization of azoles, such as pyrazoles, triazoles, 1,2,4-oxadiazoles, and imidazoles, the potential of carbonyl-substituted 1,3,4-oxadiazole systems has surprisingly never been explored in energetic materials. In this study, the tetrazole-based energetic material 2,2'-bis(dinitromethyl)-2,2'-5,5'-bitetrazole () reacted with nitrosulfur mixed acid, successfully yielding the ketone-based energetic compound [2,2'-bi(1,3,4-oxadiazole)]-5,5'(4,4')-dione () featuring a bis(1,3,4-oxadiazole) skeleton.

High-resolution electronic tactile displays stand to transform haptics for remote machine operation, virtual reality, and digital information access for people who are blind or visually impaired. Yet, increasing the resolution of these displays requires increasing the number of individually addressable actuators while simultaneously reducing their total surface area, power consumption, and weight, challenges most evidently reflected in the dearth of affordable multiline braille displays. Blending principles from soft robotics, microfluidics, and nonlinear mechanics, we introduce a 10-dot-by-10-dot array of 2-millimeter-diameter, combustion-powered, eversible soft actuators that individually rise in 0.

In magnetic-fusion devices, magnetohydrodynamic (MHD) disturbances such as edge-localized modes (ELMs) have interesting similarities to explosive dynamical events observed in space. Various models for the mechanisms triggering such disturbances have been proposed. However, current studies have focused on developing methods for controlling such effects based on empirical scaling.
