PatchRNN: A Multi-Scale Decoupled and Structure-Aware Framework for Long-Term Time Series Forecasting

Long-term time series forecasting is important in energy, transportation, and meteorology, yet existing methods struggle to model multi-scale features and preserve local sequence structure. We propose PatchRNN, a decomposition- and structure-aware framework for multivariate forec...

Scaling law of piles subjected to dynamic loads for centrifuge model tests. Part Ⅰ: vertical dynamic similarity

In response to the current insufficient in research on dynamic similarity of piles in centrifuge model tests, vertical dynamic similarity conditions through analytical modeling of pile-soil dynamic interaction is obtained in this study. A design approach for model piles is propos...

Analytical and numerical solutions for the staged pressure filtration-electroosmotic dewatering process of slurry

High-water-content slurry is difficult to dewater efficiently because of its low permeability, high compressibility, and strong water retention, hindering construction-waste reduction and resource utilization. This study develops a staged analytical-numerical model for pressure f...

A tolerance-based framework for optimizing profile sampling intervals in joint infilling assessment and shear strength prediction

The accurate assessment of joint infilling is critical for reliably estimating the shear strength of rock masses. While common practice often follows the International Society for Rock Mechanics (ISRM) suggestion of using a sampling interval ( ∆L ) equal to 2% of the total sample...

Local scour effects on the bearing characteristics of the hybrid skirted foundation considering combined loads

This study investigates the effects of local scour on the load-bearing performance of the hybrid skirted foundations subjected to combined loading, using a series of finite element model analyses. A comprehensive numerical model was established and validated against existing fiel...

GNSS monitoring and stability evolution mechanism of the S-J1 deformation body in the lower reaches of the Jinsha River

Catastrophic landslides triggered by reservoir impoundment represent one of the most destructive geohazards in the field of hydropower engineering, posing significant threats to human lives, property, and the long-term operational safety of critical infrastructure. A large hydrop...

Structural Parameter Optimization of a Downward Air Duct Dust Collector Based on Flow Field Uniformity Analysis: CFD-DPM Approach

Abstract The issue of dust pollution in mine roadways and tunnel excavation operations has become increasingly severe. This study systematically investigates, for the first time, to the best of our knowledge, the influence mechanisms of partition plates and tube sheet structures...

Mefatinib versus gefitinib as a first-line treatment for EGFR-mutated non-small cell lung cancer: a randomized, double-blind, multicenter phase III study

Mefatinib, a novel second-generation epidermal growth factor (EGFR) tyrosine kinase inhibitor that has shown promising antitumor activity in targeting non-small cell lung cancer (NSCLC) with common and uncommon EGFR- activating mutations. In this phase III, randomized, double-bli...

Dynamic Response Analysis of IEA 15 MW FOWT Under Extreme Focused Wave–Wind Conditions Based on Multi-Region Coupled Method

This study employs a multi-region coupled method to investigate the motion responses and aerodynamic load variations of the IEA 15 MW semi-submersible floating wind turbine (FOWT) under extreme focused wave conditions. The methodology employs the self-developed MRFoam solver with...

On the Vibration-Based Modal Parameter Identification of Large Wind Turbine Blades

The blades directly affect the safety and power generation efficiency of the wind turbines. With the blade size increases, the reliable modal identification becomes important for vibration-based health monitoring. Although operational modal analysis (OMA) technique has been used...
