Model test and particle flow numerical simulation of soil arching effect for unsaturated sandy soil tunnel

open access: yesRock and Soil Mechanics, 2021
The apparent cohesion caused by matric suction makes the mechanical properties of unsaturated sand significantly different from those of dry sand. In order to study the soil arching effect of the unsaturated sand tunnel, trapdoor tests with different ...

Experimental Evidence for Partially Dehydrogenated ε-FeOOH

open access: yesCrystals, 2019
Hydrogen in hydrous minerals becomes highly mobile as it approaches the geotherm of the lower mantle. Its diffusion and transportation behaviors under high pressure are important in order to understand the crystallographic properties of hydrous minerals.

Trajectory and stability of Lagrangian point $L_2$ in the Sun-Earth system

open access: yes, 2010
This paper describes design of the trajectory and analysis of the stability of collinear point $L_2$ in the Sun-Earth system. The modified restricted three body problem with additional gravitational potential from the belt is used as the model for the ...

Pressure-tuning of the electron-phonon coupling: the insulator to metal transition in manganites [PDF]

open access: yes, 2003
A comprehensive understanding of the physical origin of the unique magnetic and transport properties of A_(1-x)A'^xMnO_3 manganites (A = trivalent rare-earth and A' = divalent alkali-earth metal) is still far from being achieved.

Psychological Safety Among Interprofessional Pediatric Oncology Teams in Germany: A Nationwide Survey

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Psychological safety (PS) is essential for teamwork, communication, and patient safety in complex healthcare environments. In pediatric oncology, interprofessional collaboration occurs under high emotional and organizational demands. Low PS may increase stress, burnout, and adverse events.

A diamond-bearing core-mantle boundary on Mercury

open access: yesNature Communications
Abundant carbon was identified on Mercury by MESSENGER, which is interpreted as the remnant of a primordial graphite flotation crust, suggesting that the magma ocean and core were saturated in carbon.
