Measurements of ice-ice friction coefficients at low sliding velocities
非回転式の摩擦測定器を製作し,低温室(-10℃)で滑り速度10-7m/s~10-3m/sおよび垂直応力123,245,368kPaにおける氷・氷および氷・他物質(ガラス,花崗岩)の摩擦測定を行った.氷・氷摩擦係数は,速度を10-4m/sから10-7m/sまで減少させるにつれて,0.1から1まで増加した.一方,氷・ガラス摩擦では速度10-3m/sから10-5m/sまで減少させるにつれて,0.04から0.02まで減少した.この速度領域における氷・氷摩擦係数が,低速度ほど増加する結果は,これまでの伝統的な凝着理論,すなわち摩擦面の氷の塑性流動だけでは説明できない.氷・花崗岩の摩擦係数は,速度を10-3m/sから10-6m/sまで減少させるにつれて,はじめ増加した後に減少した.氷 ...

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study
ABSTRACT Objective High‐altitude headache (HAH) is a common neurological condition associated with rapid ascent to high altitude. The pathophysiological mechanisms underlying HAH remain incompletely understood. Calcitonin gene‐related peptide (CGRP), a neuropeptide implicated in migraine pathophysiology, may play a key role in the pathophysiology of ...

ABSTRACT Objective Facioscapulohumeral muscular dystrophy (FSHD) is one of the most debilitating and common muscular dystrophies. Despite its severity, no approved therapy exists for FSHD patients. However, several therapeutic candidates are currently under development, and some have recently entered clinical trials, marking the need for reliable ...

Objective Frailty occurs prematurely in rheumatoid arthritis (RA) and is associated with poor health outcomes. We compared the performance of four frailty instruments, including a pragmatic alternative measure using chair sit‐to‐stand (STS), and evaluated their abilities to predict poor health outcomes.

Effect of velocity in icing scaling tests [PDF]
This paper presents additional results of a study first published in 1999 to determine the effect of scale velocity on scaled icing test results. Reference tests were made with a 53.3-cm-chord NACA 0012 airfoil model in the NASA Glenn Icing Research Tunnel at an airspeed of 67 m/s, an MVD of 40 microns, and an LWC of 0.6 g/cu m.

What Do Large Language Models Know About Materials?
If large language models (LLMs) are to be used inside the material discovery and engineering process, they must be benchmarked for the accurateness of intrinsic material knowledge. The current work introduces 1) a reasoning process through the processing–structure–property–performance chain and 2) a tool for benchmarking knowledge of LLMs concerning ...

The quality of sea ice velocity estimates [PDF]
Several aspects of observed and estimated velocities for Arctic sea ice are explored. The long‐term mean ice motion field and associated variance are derived using 15 years (over 85,000 observations) of daily buoy motions. The mean field is separated into the part due to long‐term currents and internal ice stress and the part due to mean winds.

Low‐voltage FIB‐SEM tomography combined with a image preprocessing pipeline improves phase contrast and enables reliable machine‐learning segmentation of conductive networks in lithium‐ion battery electrodes. Structural descriptors are extracted from segmented images, done semimanually and automated, and compared.

Laser‐Induced Graphene from Waste Almond Shells
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

We report a unique color‐sensing phenomenon of a TiO2/SbSI:Sb2S3 device utilizing X‐ray absorption. Based on the revealed penetration and adsorption of water onto TiO2, we successfully improved the color response speed and sensitivity by incorporating a hydrophilic polymer interlayer, thereby opening up opportunities for photodetection applications ...
