Elephant‐Skin‐Inspired Porous Cementitious Tiles with Programmable Crack Networks for Passive Cooling

Advanced Materials, EarlyView.
Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion

Advanced Robotics Research, EarlyView.
A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

‘Hurry Up and Get Me out of Here’: The Experience of People Under 65 Years (Still) Stuck in Aged Care

Australian Journal of Social Issues, EarlyView.
ABSTRACT Following the Royal Commission into Aged Care Quality and Safety, the Australian Government set a target for no‐one under 65 years of age to be living in residential aged care (RAC) by 2025. The numbers of young people in residential aged care (YPIRAC) have significantly declined since the start of the targets.

Migration characteristics and disaster reduction and erosion prevention mechanism of thick and hard roof in deep filling mining

Meitan kexue jishu
To address the issue of rock burst disasters induced by the fracture of thick-hard roof strata, focuses on deep thick and hard roof. By integrating theoretical analysis, engineering experiments, and field monitoring, the fracture characteristics of thick-

Extent of Sinus Surgery Is Associated With Disease Control in Biologic Treated Type 2 Dominant CRS

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background A greater benefit of biologics is observed after surgery in Type 2 chronic rhinosinusitis with nasal polyps (CRSwNP). However, the extent of surgery remains undefined in many studies. This study evaluated the extent of surgery on disease control in patients receiving biologics for refractory Type 2 dominant CRSwNP.

Fracture instability and pre-splitting weakening characteristics of composite hard roof under mining action

Meitan xuebao
In the process of mining, the elastic energy release of hard roof breaking is easy to induce impact disaster. In particular, there are multi-layer hard roofs above the coal seams in the Shaanxi-Inner Mongolia region.

Shearer mining application to soft thin-seam with hard roof

Procedia Earth and Planetary Science, 2009
AbstractStudy status on shearer mining in thin seams in the world is introduced. Base on the geological conditions of instable and soft thin-seam with hard roof in Caoyao Coal Mine of Yima Coal Group, China, and combined with related parameters of strata behaviors at coal faces, the paper concludes that the strata control on the thin-seam coal face is ...

Analysis of Overburden Structure and Pressure‐Relief Effect of Hard Roof Blasting and Cutting [PDF]

Advances in Civil Engineering, 2019
When studying the pressure‐relief effect of hard roof blasting and cutting, the roof‐cutting position and angle obviously affect the stability of the rock surrounding the gob‐side entry (GSE). In this paper, control of the large deformation of rock surrounding the GSE is evaluated on the basis of the overlying structure and pressure‐relief principle ...

Complications and Clinical Outcomes Following Modified Endoscopic Denker's With Pyriform Aperture Preservation: A Prospective Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background The modified endoscopic Denker's (MED) approach provides access to all maxillary sinus (MS) walls for resection of various MS and retromaxillary pathologies, but the anteromedial maxilla has historically been resected. This study determined complication rates and outcomes following MED with pyriform aperture (PA) preservation ...

Study on Fracture and Stress Evolution Characteristics of Ultra-Thick Hard Sandstone Roof in the Fully Mechanized Mining Face with Large Mining Height: A Case Study of Xiaojihan Coal Mine in Western China

Advances in Civil Engineering, 2018
Ultra-thick hard sandstone roofs present high thickness, poor delamination, and wide caving range. The strata pressure of the working face during actual mining increases, having a significant influence on the safe mining of the working face.
