Effect of exercise training on the swimming behaviour and rheotaxis of .

is a key stocking species in the upper Yangtze River. To determine the appropriate intensity and duration of exercise training for enhancing their field survival rate, we examined the changes in swimming capacity and rheotaxis between the trained group (exercised at 60% critical swimming speed for 6 hours daily) and the control group (reared in static water) under different training intensities and durations. Results would help explore optimal pre-release exercise protocols for hatchery-reared fish.

Deep Ensemble Learning Based on Multi-Form Fusion in Gearbox Fault Recognition.

Considering the problems of having insufficient fault identification from single information sources in actual industrial environments, and different information sensitivity in multi-information source data, and different sensitivity of artificial feature extraction, which can lead to difficulties of effective fusion of equipment information, insufficient state representation ability, low fault identification accuracy, and poor robustness, a multi-information fusion fault identification network model based on deep ensemble learning is proposed. The network is composed of multiple sub-feature extraction units and feature fusion units. Firstly, the fault feature mapping information of each information source is extracted and stored in different sub-models, and then, the features of each sub-model are fused by the feature fusion unit.

Research and design of TiN/TiAlN coated integral cemented carbide reamers under high cutting-speed and high feed-rate machining conditions.

The development of high-performance reamers made of Cemented carbide and coating materials is an important direction in mechanical finishing.

This paper takes the high cutting- speed and high feed-rate mechanical finishing of 45 steel as the experimental condition and the production site machining as the background to scientifically investigate the factors affecting the performance of the TiN/TiAlN coated Integral Cemented carbide reamer.

Multiple high-order topological states with high-order resonant bands in kagome lattice phononic crystal with resonant cavitiesa).

The topological phase of phononic crystals has garnered significant attention in the design of systems for confining and manipulating acoustic waves due to the robustness of topological states within bandgaps. In this work, we propose a kagome tight-binding model phononic crystal that utilizes the resonant effect coupling between cavities for airborne sound. The topological phase transition within high-order resonant bandgaps is achieved by tuning the coupling strength with the nontrivial phase characterized by a shrunken lattice.

However, the "extensive" and "extensive" urban development mode restricts the sustainable development of Chinese cities. This paper establishes a theoretical hypothesis that transport infrastructure construction affects urban sustainable development, uses the panel data of Chinese cities from 2006 to 2021 to empirically analyze the impact and mechanism of transport infrastructure construction on urban sustainable development, and explores the heterogeneity caused by differences in sample regions and time intervals.

Rationally Engineered Adenosine A2A Decoy Receptor for Reversing Immunosuppression of Breast Cancer.

The hypoxia-adenosine axis drives tumor immune evasion by activating A2AR on immune cells, and current therapeutic strategies predominantly rely on small-molecule antagonists. However, these agents face limitations including short plasma half-life, off-target effects on other adenosine receptors, and inability to remodel the physical barriers of solid tumors. To overcome these challenges, this work designs a novel adenosine-A2AR protein inhibitor, A2AR-Fc, which demonstrates a notably high binding affinity for NECA and exhibits good water solubility and stability both in vitro and in vivo.

Development of a novel and highly efficient catalyst-free mediated "oxidant-oxidant" process for enhanced decontamination of water contaminants.
