Flood redistribution and hydraulic responses to controlled levee breaching in highly Leveed urban rivers

Study region Study region: The upper reach of the Ganjiang River in Ganzhou, Jiangxi Province, China, where rapid urbanization and extensive levee systems have increased exposure to extreme flood hazards. Study focus A coupled 1D-2D hydrodynamic model (GAST) was applied to simula...

Geometrically Matched Bridge Adsorption: Boosting Polysulfide Conversion Kinetics via Fe 2 N 6 Catalysts

ABSTRACT The commercialization of lithium–sulfur batteries (LSBs) is hindered by sluggish lithium polysulfides (LiPSs) conversion kinetics. While single‐atom catalysts (SACs) are widely used, their rigid coordination often causes severe “geometric mismatches” with LiPSs, leading...

Condition-Aware Performance Health Index and Multi-Source Signal Mapping for Degradation Trend Identification in Hydropower Units

Hydropower units often operate under complex conditions caused by water head change, guide-vane regulation, and load adjustment. These condition changes make it difficult to identify gradual performance degradation from monitoring signals alone. To solve this problem, this paper...

Decoupling Ion–Dipole Interactions via Competitive Coordination for Durable Dendrite-Free Zinc Metal Batteries

Abstract The aqueous zinc metal batteries (AZMBs) are famous for high-safety and high-energy-density, but limited by severe challenges around the Helmholtz plane layer such as the strong ion–dipole interactions between Zn 2+ and H 2 O, resulting in slow desolvation processes and...

Hydraulic Mechanism and Flow Pattern Optimization of Special Orthogonal Lateral-Intake Pumping Stations in Coastal Hydraulic Hubs

Special orthogonal lateral-intake pumping stations on coastal plains face severe lateral deflection and recirculation in the approach channel and forebay. Their underlying evolutionary mechanisms remain unclear, and conventional rectification methods cause substantial hydraulic l...

Zonal Variations in Cavern Inflow Features and Water Management of Pumped Hydro Storage in China

Pumped hydro storage is a well-established and reliable form of energy storage, with construction scale expanding steadily in recent years. Underground cavern excavation is an indispensable part of pumped storage construction, while sustained cavern inflow poses potential threats...

Compact Terahertz Vortex Beam Source Based on Smith–Purcell Radiation and a Double‐Layer Metasurface

ABSTRACT Smith–Purcell (SP) radiation, a frequency‐tunable radiation mechanism excited by moving electrons, is a promising route toward compact light sources operating from the terahertz to optical regimes. Vortex beams carrying orbital angular momentum (OAM) have helical phase f...

FFT-Based Multiscale Frequency Decomposition for Atmospheric Lidar Attenuated Backscatter Profile Forecasting

Atmospheric light detection and ranging (lidar) measurements of the attenuated backscatter coefficient (ABSC) form high-dimensional vertical profiles that vary across multiple temporal scales. Directly processing the original time-domain sequence with a single prediction structur...

From “Time is money” to “Time is life”: cyberslacking and the moralization of time in contemporary China

This article investigates cyberslacking in contemporary China through the lens of time moralization, framing it as a morally contested response to capitalist temporal regimes, rather than mere individual deviance. Drawing on 35 semi-structured interviews within the Douban group “...

Study on heterodyne detection efficiency of partially coherent beams with different polarization state combinations in atmospheric turbulence

Abstract Expressions for the heterodyne detection efficiency of the partially coherent electromagnetic Gaussian–Schell model (EGSM) in atmospheric turbulence were derived. In this study, the signal and local oscillator beams were configured in five different polarization states:...
