Exploring the water status of drip-irrigated apple trees based on variation in predawn stem water potential

Determining irrigation timing based on plant water status is essential for drip-irrigated apple orchards. Stem water potential (Ψ stem ) has been suggested as a tool for precision irrigation in fruit trees, but clear thresholds for drip-irrigated apple trees are lacking. In 2023...

A kinematic-muscle hybrid synergy-assisted EMG-driven NMSK model for muscle activation and joint moment prediction with minimal sensors

Cross-country sit-skiing relies heavily on upper-limb power, with double poling (DP) propulsion generated by coordinated pole forces and trunk rotation. Estimating shoulder and elbow joint moments and muscle forces during DP is crucial for technique optimization and injury-risk r...

Investigation on real-time permeability evolution of granite under subcritical and supercritical water conditions

The in situ permeability evolution of granite is critical for efficiently developing subcritical and supercritical geothermal resources (200–400 °C). Herein, a high-temperature, high-pressure triaxial seepage system was employed to compare the real-time permeability evolution of...

Experimental study on inhibition mechanism of composite inhibitors for coal spontaneous combustion at critical temperature

To elucidate the inhibition mechanism of composite inhibitors during coal spontaneous combustion under a selected critical-temperature condition, three coals with different ranks were investigated. Temperature-programmed oxidation coupled with gas chromatography, in-situ Fourier...

Characteristics and Control of Severe Strata Behavior in Top-Coal Caving Gate Roads of Extra-Thick Coal Seams Beneath Goafs

In close-distance coal seam mining, the long-term static high-stress field induced by remnant pillars in the overlying goaf superimposes with the dynamic load disturbance from fully mechanized top-coal caving (TCC) in the underlying extra-thick seam. This superposition leads to s...

Investigation into Adsorption Performance and Mechanism for Copper on Red Mud Modified Biochar

Peanut shells from Shanxi Province were used as the biomass feedstock to prepare three red-mud-modified biochars at red mud-to-peanut-shell mass ratios of 1:1 (RMBC1), 1:5 (RMBC2), and 1:10 (RMBC3) through suspension loading followed by pyrolysis. Their adsorption behavior and me...

Effect of Prefabricated Borehole Diameter on the Nonlinear Mechanical Response of Coal–Rock Composite Specimens Under Dynamic Loading

To investigate the effect of prefabricated borehole diameter on the dynamic response of coal–rock composite specimens, split Hopkinson pressure bar (SHPB) tests were conducted on specimens without a borehole and with borehole diameters of 4, 6, and 8 mm. Twelve specimens were tes...

Mitochondrial Transplantation Rejuvenates Aging Heart by Restoring Mitophagy Flux via the HIF ‐3α‐ BNIP3 Axis

Mitochondrial quality control is severely impaired in the aging heart, largely attributed to disrupted mitophagy homeostasis. However, the key molecular drivers remain poorly defined, and the translational value of mitochondria-targeted therapy for cardiac aging is still underexp...

Pollution characteristics, migration and transformation, and health risk assessment of polycyclic aromatic hydrocarbons in environmental media of prototype coking plants in Shanxi, China

Environmental context Coking is one of the important emission sources of polycyclic aromatic hydrocarbons (PAHs). We analysed distribution characteristics of PAHs emitted from the coke oven top and in environmental media in the prototype coking plants. The migration and transform...

Relaxation Piezoionic Hydrogel for Self-Powered, Self-Decoupled Monitoring of Finger Rehabilitation

Abstract Hand motor dysfunction involves limited finger flexion and impaired release control, making finger flexion angles and active relaxation ability key metrics for rehabilitation assessment. However, existing flexible electronics quantify deformation amplitude, while deforma...
