Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile
Fire and Materials, EarlyView.ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Intelligent Continuum Micromachines in Complex Confined Spaces
SmartBot, EarlyView.The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Speech Recognition Deficits in Presbyacusis: Links to Cortical Structural and Functional Alterations
World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Objective To characterize speech recognition in presbyacusis and its associated neurophysiological and cortical structural features, and to explore structure‐function‐behavior relationships within the presbyacusis phenotype. Methods Thirty elderly patients with presbyacusis(HI) and thirty‐three healthy young controls(NH) completed a behavioral

The Journal of Physiology, EarlyView.Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...
