An Improved True Triaxial Hoek–Brown Strength Criterion
工程科学与技术, 2023 Hoek–Brown strength criterion has been widely used in rock and rock mechanics analysis, rock slope stability analysis, rock tunnel design, and other fields, but the conventional Hoek–Brown strength criterion does not consider the influence of ...

Considerations for Discrete Element Modeling of Rock Cutting [PDF]
, 2013 This study attempts to build a framework within the Discrete Element Method (DEM) to produce a reliable predictive tool in rock cutting applications, such that the cutting forces and fragmentation process are reasonably estimated. The study is limited to

The strength of hard-rock pillars
, 2000 : Observations of pillar failures in Canadian hard-rock mines indicate that the dominant mode of failure is progressive slabbing and spalling. Empirical formulas developed for the stability of hard-rock pillars suggest that the pillar strength is ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background X‐linked adrenoleukodystrophy (X‐ALD) is a neurometabolic disorder caused by pathogenic variants in ABCD1, leading to slowly progressive spinal cord disease in nearly all affected men. Sensitive biomarkers to quantify disease severity and predict progression are needed for clinical care and trial design.

Arthritis Care &Research, EarlyView.Objective Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies.

Modelling rock slope behaviour and evolution with reference to Northern Spain and Southern Jordan [PDF]
, 2004 The geomorphological behaviour of steep jointed rock slopes has been studied using distinct element computer models. In order to model steep slopes effectively, methodologies need to be combined from the studies of environmental modellers ...

Back-analysis of schistose rock mass strength parameters based on displacement monitoring data
, 2012 This paper presents a displacement based back-analysis method for the determination of the elastic modulus (E), cohesive strength (C), friction angle (φ) and in situ stress of a schistose rock mass. Orthogonal experimental design (OED) method was used to

Distinct Systemic Sclerosis Phenotypes Related to Ethnicity: An Opportunity to Personalize Care?
Arthritis Care &Research, EarlyView.Objective The objective is to describe and compare demographic, clinical, and serological characteristics of patients with systemic sclerosis (SSc) according to ethnic background. Methods Participants enrolled in the Canadian Scleroderma Research Group cohort who self‐identified to a single ethnicity group were included.
