TL;DR: The developed algorithm could determine sleep/wake states from activity intensity data obtained with the FS-750 with sensitivity and specificity equivalent to that determined with conventional actigraphs, and is a promising tool for advancing sleep studies at home and in remote sleep medicine.

TL;DR: It is demonstrated that sleep/wake activity in young to middle-aged healthy subjects can be assessed with a reliability comparable to that of conventional actigraphy through LC waist actigraphY and the optimal S/W scoring algorithm.

TL;DR: In this paper, a method to simulate ductile tearing in large-scale pipes using finite element analysis is proposed, based on the stress-modified fracture strain model, and an element-size-dependent critical damage model is also introduced in damage simulations.

TL;DR: In this article, the authors presented ductile fracture simulation using the GTN (Gurson-Tvergaard-Needleman) model of through-wall cracked STPT410 carbon steel pipe test under pure bending.

TL;DR: In this paper, a welded joint of Mod. 9Cr-1Mo steel, whose Type IV cracking behavior is an important issue to be assessed, was subjected to a series of creep crack propagation experiments in order to clarify the applicability of existing standard ASTM E1457-98.
