From microbial tryptophan metabolism to crystal injury: an IPA – AhR checkpoint in calcium oxalate nephropathy

Calcium oxalate nephrolithiasis is commonly viewed as a consequence of urinary supersaturation, although crystal retention and renal injury are also influenced by gut microbiota dysbiosis and local tissue environment. In a recent study by Li et al, published in The Journal of Pat...

Research on sports exercise posture monitoring and energy consumption law based on energy power sensors

This study develops a self-powered multimodal wearable sensing framework for simultaneous sports-posture recognition and human energy-expenditure estimation. The wearable node integrates triaxial acceleration and angular-velocity sensing with an auxiliary micro-energy-harvesting...

Phase transition in new macroscopic continuum model considering forward–backward looking information and electronic throttle angle dynamics under overtaking effect

In the context of Connected Automated Vehicles (CAVs), overtaking behavior is a key factor leading to traffic instability. In real-world traffic scenario, driving decisions depend not only on forward-looking information but also on rear-view effects and vehicle dynamic control pa...

Decarbonylative arylation/alkylation of heteroarenes with aldehydes via triplet synergistic catalysis

The development of sustainable synthetic routes from aldehydes to functionalized heteroarenes is an important goal in organic synthesis, owing to the low cost and ready accessibility of aldehydes. However, the high bond dissociation energy (BDE) of the Ar-C(O) bond makes the phot...

Microbial Network Complexity Emerges as a Key Predictor of Soil Multifunctionality Across Alfalfa Fields of Different Planting Years

Long-term alfalfa monoculture can lead to soil degradation, yet how microbial community attributes drive changes in soil multifunctionality (SMF) remains poorly understood. Here, we examined SMF and microbial community attributes across alfalfa fields over three planting year per...

The correlation between the gyrB genetic distance and the digital DNA-DNA hybridization value for the genus Micromonospora and taxonomic studies on Micromonospora cynarae sp. nov

An early study on Micromonospora species indicated that a gyrB (DNA gyrase subunit B) genetic distance about 0.014 would equal to the 70% value in DNA hybridization value. However, based on the corresponding relation of gyrB genetic distance and dDDH (digital DNA–DNA hybridizatio...

Photocatalytic Four-Component Sulfonylation/ Ipso -Spirocyclization of N -Arylpropiolamides with Thianthrenium Salts, DABSO and H2O: Access to 3-Sulfonyl-Azaspiro[4.5]trienones

Abstract A visible-light-induced sodium fluorescein-catalyzed four-component cascade reaction of N-arylpropiolamides, aryl thianthrenium salts, DABSO, and H2O has been developed, providing efficient access to diverse 3-sulfonyl-azaspiro[4.5]trienones in moderate to good yields. T...

Strain‐Buffering Layered/Rocksalt Heterostructure Constructed via Oxygen Redox Activation for Durable O3‐Type Layered Transition Metal Oxides

ABSTRACT Harnessing anionic oxygen redox is pivotal for boosting the capacity of O3‐type layered transition metal oxides for sodium ion batteries (SIBs), yet it often triggers severe lattice distortion and irreversible oxygen release. Herein, we propose an in situ electrochemical...

Intelligent decision analytics with recursive learning for competitive sports management

The increasing availability of sports performance data has created new opportunities for data-supported decision-making in competitive sports management. However, redundant and strongly correlated performance indicators can increase analytical complexity and distort the influence...

Coupling Effects of Texture Density and Counterpart Material Hardness on the Dry Sliding Friction of TC4 Titanium Alloy

Circular microtextures with area densities of 5%, 10%, 15%, and 20% were fabricated on TC4 titanium alloy surfaces and tested under dry sliding conditions against four counterpart balls of varying hardness (Brass, SUS304, AISI 52100, and K20). Through coefficient of friction (COF...
