An optical fiber hydrogen sensor using a palladium-coated ball lens [PDF]

, 2015
A self-referenced optical fiber refractometer using a ball lens as a sensor head has been developed and characterized. A 350-μm ball lens created at the tip of a single mode fiber has been coated with a 40-nm optically thin layer of palladium that reacts

Super‐Refractory Status Epilepticus (SRSE) in a Patient With Compound Heterozygous OPA1 Variants: Case Report and Literature Review

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

A 73‐Year‐Old Man With Several Years of Difficulty Climbing Stairs and Frequent Tripping

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 73‐year‐old man presented with progressive weakness and atrophy predominantly affecting the distal finger flexors and quadriceps muscles. Electrophysiological studies demonstrated mixed myogenic and neurogenic features. Muscle MRI showed inflammatory changes, and muscle biopsy revealed granulomatous myositis with histologic features ...

Spectroscopic studies of the mechanism for hydrogen-induced exfoliation of InP [PDF]

, 2005
The motion and bonding configurations of hydrogen in InP are studied after proton implantation and subsequent annealing, using Fourier transform infrared (FTIR) spectroscopy. It is demonstrated that, as implanted, hydrogen is distributed predominantly in

Discussion on Road Reflection Crack and Control

IOP Conference Series: Materials Science and Engineering, 2020
Abstract This paper focused on the problems encountered in the road construction of a coal-fired power plant in the Philippines as an example. Some cracks and damage appeared in the roadbed after the road concrete base layer has been built.

Review of reflective cracking in composite pavements

International Journal of Pavement Research and Technology, 2020
Reflective cracking is identified as the main weakness of composite pavement in airfield and highways forcing the authorities to devote a large portion of their budget to rehabilitation and/or reconstruction of the existing composite pavements. It is, therefore, very important to have a better understanding of the reflective cracking mechanism to ...

TBK1‐Associated Primary Lateral Sclerosis Followed by Right Temporal Variant Frontotemporal Dementia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT We report a 58‐year‐old woman with a novel splice‐site variant in the TANK‐binding kinase 1 (TBK1:c.993–2A>C p.Ala332TyrfsTer39) who sequentially developed primary lateral sclerosis (PLS) followed by right temporal variant frontotemporal dementia (rtvFTD). Neuroimaging demonstrated right anterior temporal atrophy before cognitive symptoms, and

Enhancing crack detection in railway tracks through AI-optimized ultrasonic guided wave modes

Biomimetic Intelligence and Robotics
The utilization of ultrasonic guided wave technology for detecting cracks in railway tracks involves analyzing echo signals produced by the interaction of cracks with guided wave modes to achieve precise crack localization, which is extremely important ...
