Patch–Terrain Coupling and Resistance-Based Connectivity Adjustment for Assessing Contiguous Cropland Consolidation Potential in Hilly Terraced Regions: A Case Study of Huangzhong District, China

Cropland fragmentation remains a major constraint on agricultural mechanization, land consolidation, and cropland protection in hilly and mountainous regions. In terraced landscapes, cropland patches that appear close in planar space may nevertheless be difficult to connect becau...

Band Degeneracy and Liquid-like Dynamics in Intercalated La2O2Te/BiAgSeO Thermoelectrics

Abstract Interlayer modulation of layered oxychalcogenide superlattices provides a strategy to decouple electron–phonon transport for high-performance thermoelectric (TE) materials. Herein, an intercalated oxychalcogenide superlattice (La4Bi2Ag2Se2Te2O6) is theoretically designed...

Hydration behavior and phase evolution of low-activity granulated blast furnace slag under mechanical-chemical activation

Low-activity granulated blast furnace slag (GBFS) has inherent limitations, including low chemical reactivity, sluggish hydration kinetics, and insufficient early-age strength development, which constrain its utilization as a cementitious material. To clarify the correlation betw...

Economic Scheduling Strategies for Climate Management in a Venlo-Type Rose Greenhouse Under Time-of-Use Tariffs and CO2 Supplementation Costs

Greenhouse cultivation plays an important role in supporting stable and high-quality horticultural production by providing controlled environmental conditions under variable outdoor climates. However, regulating temperature, humidity, CO2 concentration, and light requires substan...

A novel hourly PM2.5 concentration prediction model using IMSTL-FVMD-HLDT hybrid architecture with Adam optimized by Schrödinger search strategy

PM 2.5 concentration time series are characterized by obvious chaotic behavior, mutually superimposed multi-period components and notable temporal fluctuations, which pose considerable difficulties to the high-precision prediction of PM 2.5 concentration. To address this issue, t...

Bi-Level Coordinated Optimal Operation of a Multi-Microgrid System with Shared Energy Storage

To improve sustainable operation of multi-microgrid (MMG) systems with high penetration of renewable energy, this paper proposes a bi-level coordinated optimization method based on Stackelberg and cooperative games to address wind–photovoltaic output fluctuations, stakeholder coo...

Slurry dewatering characteristics under synergistic mechanical pressure and electro-osmosis at constant current

Pressure-assisted electro-osmosis is effective for deep dewatering of high-moisture clay slurries, but the coupling effects of mechanical pressure and constant current under two-sided drainage, along with drainage redistribution and energy consumption, remain unclear. Using a sel...

Shear-creep-induced strength degradation of soft–hard interbedded rock masses controlled by layer-thickness ratio: implications for progressive failure of anti-dip slopes

Anti-dip slopes with gently dipping soft–hard interbedded strata (GD-SHIS anti-dip slopes) may exhibit relatively high resistance under short-term cross-layer shearing. However, sustained shear loading can induce soft-layer deformation, shear-parameter degradation, and delayed pr...

A novel dynamic model parameters identification method for robotic manipulator based on the feasible physical constraints

The dynamic model of robots plays a crucial role in control tasks. The traditional Coulomb-viscous friction model inadequately describes friction torque, and the conventional identification strategy is ineffective in accurately identifying dynamic models with full physical parame...

Force–Energy Coordination Response and Size Effect of Gyroid‐Type TPMS Lattices Based on Noniterative Reference Stress Field Mapping

Graded triply periodic minimal surface (TPMS) lattices improve load‐bearing and energy absorption capacity through relative‐density tailoring. However, noniterative mapping of a reference stress field to a continuous relative‐density field remains insufficiently investigated. A n...
