Analysis of Dry Sliding Wear Behaviour of Aluminium-Fly Ash Composites: The Taguchi Approach

open access: yesAdvances in Mechanical Engineering, 2013
Dry sliding wear test was conducted on Al-fly ash composites employing pin-on-disc wear testing rig. The influence of parameters such as weight percentage of fly ash, load, and sliding speed on the wear rate of specimens was investigated.

The Role of Calcitonin Gene‐Related Peptide in High‐Altitude Headache: A Prospective Field Study

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
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 ...

There is logic in logit – including wear rate in Colding’s tool wear model [PDF]

open access: yesProcedia Manufacturing, 2019
Modelling of tool wear in metal cutting processes has been the foundation of the field since the famous Taylor's tool life model. Tool wear models have been developed for planning machining operations and calculating production costs. Most wear models do not include wear rate in the model but rather just the final wear at end of tool life, i.e.

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

Condition-Based Monitoring for Marine Engine Maintenance by Analyzing Drain Cylinder Oil Sample

open access: yesTribology Online, 2022
Improvement of condition-based monitoring for large bore 2-stroke marine engine cylinder liners and piston rings require close monitoring of anomaly wear elements in drain cylinder oil.

Factors Associated With the Rising Trend in Self‐Reported Cognitive Disability Among U.S. Adults Aged 18–39 From 2013–2024

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Building on our prior Behavioral Risk Factor Surveillance System analysis identifying adults aged 18–39 as the primary driver of the national increase in self‐reported cognitive disability, we examined factors associated with this rise using 2013–2024 U.S. BRFSS data. Methods We analyzed U.S.

Association Between Neurofilament Light Chain and Real‐World Ambulatory Function in Progressive MS

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurofilament light chain (NfL) is a biomarker of neuroaxonal injury in multiple sclerosis (MS), yet associations with functional outcomes remain unclear. Longitudinal associations between serum NfL (sNfL) and daily step count (STEPS) from wearable devices were assessed in a large international progressive MS cohort.

Predicting UHMWPE wear: decreasing wear rate following a change in sliding direction

open access: yes, 2010
The patient demographic for total joint replacement is becoming younger and more active leading to increased performance expectations [1]. To develop new products that meet these demands, computer simulations that predict wear are emerging as potential ...

Temporal Divergence of True and False Alarms in Pediatric Nocturnal Seizure Monitoring

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
The early‐morning surge in false seizure alarms supports exploring time‐ or state‐dependent detection thresholds to reduce false detections. ABSTRACT Seizure detection devices can improve the safety of children with epilepsy, yet high false alarms limit their clinical applicability.

Exploring Wear Characteristics of AISI 1045 Steel under Variable Disc Rotation Speeds: A Tribological Investigation

open access: yesTeknik
Reliable mechanical components are the desired final product. When mechanical components come into contact with each other, there is a possibility of failure. Contact between components can result in friction leading to wear.
