Season-robust localization for autonomous robot in orchard using two-stage LiDAR points segmentation with sensor fusion

A robust cross-season, multi-route localization framework is proposed for agricultural environments with significant seasonal variations. Based on intensity-calibrated maps constructed across four seasons, a two-stage point segmentation method is employed to extract geometrically...

Deformation mechanisms and rheology of chlorite-actinolite schist and blueschist: Implications for creep behavior along the slab-mantle interface

Chlorite-actinolite schist (CAS) and blueschist represent major lithologies along the subduction plate boundary at the slab-mantle interface, yet their deformation mechanisms and rheological properties remain poorly constrained. We investigated a subduction melange in western Kyu...

Association between coronary high-intensity plaque and pericoronary adipose tissue attenuation and plaque morphology

Background: This study aimed to investigate the association between high-intensity plaque (HIP) on cardiac magnetic resonance (CMR) imaging and pericoronary adipose tissue attenuation (PCATA) and plaque burden on coronary computed tomography angiography (CCTA) in patients with ch...

L2K-ARG

Abstract The present study introduces an open-access corpus of Korean second language argumentative writing (L2K-ARG) produced by university-level learners with different first-language backgrounds. The corpus contains 484 essays written in response to three standardized prompts...

Impact of Kuala Lumpur as a tropical city on cloud formation: Numerical experiments using the WRF-UCM model

Previous satellite-based studies have shown that Greater Kuala Lumpur (GKL) consistently exhibits a higher cloud frequency than surrounding rural areas. To investigate the underlying mechanisms, numerical experiments were conducted using the Weather Research and Forecasting (WRF)...
