Annual-cycle assessment of street orientation effects on outdoor thermal comfort in a hot-summer cold-winter district

This study introduces a computationally efficient framework using Fourier harmonic regression to evaluate the annual thermal performance of street orientations in China's Hot-Summer Cold-Winter zone, revealing that the NE–SW orientation offers the optimal balance between summer shading and winter solar access while the E–W orientation presents the highest thermal risk.

Quantifying the Impact of Urban Block Morphology and Orientation on Office Building Energy Use in a Tropical City

In high-density, hot-humid Central Jakarta, a parametric study reveals that urban morphological density (site coverage and building height) overwhelmingly dominates office building energy performance by reducing cooling loads through mutual shading and lower sky view factors, rendering façade orientation virtually insignificant.

Pressure-Relief Evolution and Lagged Gas-Drainage Response of Protected Seams during Lower Protective Seam Mining in Deep Inclined Coal Seams

This study reveals that in deep inclined coal seams, the onset of strong pressure relief during lower protective seam mining does not immediately trigger synchronous gas-drainage enhancement, exhibiting a significant spatial lag and nonuniform conversion that necessitates a new compaction-based criterion and lag-corrected framework to define effective protection ranges and drainage timing.

Medium and Short-Term Wind Power Forecasting Using LCNN-Mamba Model Based on Quadratic Decomposition

This paper proposes a hybrid LCNN-Mamba model enhanced by quadratic decomposition (STL and CEEMDAN) to effectively address the non-stationarity and multiscale fluctuations in wind power data, achieving superior short-to-medium-term forecasting accuracy through the synergistic integration of local convolutional feature extraction and global state-space dependency modeling.
