Mechanical Properties and Failure Behavior of Mortar-Encased Coal Bodies under Impact Loads: Insights from Experimental Investigation [PDF]
Lithosphere, 2022 Failure of residual coal pillars under dynamic load disturbances can induce goaf collapse, ground subsidence, or coalbursts. Encasing the residual coal pillar in mortar is an effective method for reinforcing the residual coal pillar.

Heart Failure Statistics in Korea, 2020: A Report from the Korean Society of Heart Failure [PDF]
, 2021 Background and Objectives Heart failure (HF) is a disease with high morbidity and mortality. With ageing society and increasing prevalence of risk factors of HF, the prevalence of HF is expected to increase, as well. In this official report of the Korean

Advanced chronic heart failure: A position statement from the Study Group on Advanced Heart Failure of the Heart Failure Association of the European Societyof Cardiology [PDF]
, 2007 Therapy has improved the survival of heart failure (HF) patients. However, many patients progress to advanced chronic HF (ACHF). We propose a practical clinical definition and describe the characteristics of this condition.

Size-dependency of the transverse-tensile failure behavior for triaxially braided composites
, 2021 Coupon specimens of triaxially braided composites suffer significant out-of-plane tension–torsion coupled deformation along the free edges, known as free-edge effect, under uniaxial tensile/compressive loading.
