Dynamic Modeling and Analysis of Thrust Reverser Mechanism Considering Clearance Joints and Flexible Component

open access: yesAerospace, 2022
As a high-precision motion mechanism, the kinematics and dynamics of cascade thrust reverser are sensitive to the changes of nonlinear factors which are rarely considered in traditional dynamic modeling and optimization.

Identifying Trippers and Non-Trippers Based on Knee Kinematics During Obstacle-Free Walking [PDF]

open access: yes, 2018
Trips are a major cause of falls. Sagittal-plane kinematics affect clearance between the foot and obstacles, however, it is unclear which kinematic measures during obstacle-free walking are associated with avoiding a trip when encountering an obstacle ...

Non-metallic brush seals for gas turbine bearings [PDF]

open access: yes, 2004
A non-metallic brush seal has been developed as an oil seal for use in turbomachinary. Traditionally labyrinth-type seals with larger clearances have been used in such applications. Labyrinth seals have higher leakage rates and can undergo excessive wear

RaMBat: Accurate identification of medulloblastoma subtypes from diverse data sources with severe batch effects

open access: yesMolecular Oncology, EarlyView.
To integrate multiple transcriptomics data with severe batch effects for identifying MB subtypes, we developed a novel and accurate computational method named RaMBat, which leveraged subtype‐specific gene expression ranking information instead of absolute gene expression levels to address batch effects of diverse data sources.

Hepatitis C virus pharmacogenomics in Latin American populations: implications in the era of direct-acting antivirals [PDF]

open access: yes, 2017
In recent years, great progress has been made in the field of new therapeutic options for hepatitis C virus (HCV) infection. The new direct-acting antiviral agents (DAAs) represent a great hope for millions of chronically infected individuals because ...

Diabetes‐induced vascular calcification is associated with low pyrophosphate and its oral supplementation prevents calcification in diabetic mice

open access: yesFEBS Open Bio, EarlyView.
Induction of diabetes in three different mouse strains uniformly resulted in an increase in TNAP activity and a reduction in pyrophosphate (PPi) in the circulation. Inhibition of TNAP restored plasma PPi. Diabetes‐induced calcification in the media layer of the aorta was detected only in the Abcc6−/− strain, which is predisposed to ectopic ...

A Modular Low-clearance Wrist Orthosis for Improving Wrist Motion in Children with Cerebral Palsy [PDF]

open access: yes, 2014
Children with Cerebral Palsy (CP) often exhibit impairments in the coordination of the grip and lift phases of arm movements that directly impact their ability to perform activities of daily living (ADLs).

Effect of joint clearance on fatigue strength of brazed joint.

open access: yesQUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1989
The effects of joint clearance on fatigue crack initiation life and crack growth rate of brazed joint were investigated.Tes tspecimens used were butt joint of carbon stcel and stainless steel brazed with pure copper with/without an artificial defect in joint.It was inferred from the fatigue test results that fatigue life of joint depend not on crack ...

Impact of a senior research thesis on students' perceptions of scientific inquiry in distinct student populations

open access: yesFEBS Open Bio, EarlyView.
This study addressed how a senior research thesis is perceived by undergraduate students. It assessed students' perception of research skills, epistemological beliefs, and career goals in Biochemistry (science) and BDC (science‐business) students. Completing a thesis improved confidence in research skills, resilience, scientific identity, closed gender‐

Numerical and experimental study on dynamics of the planar mechanical system considering two revolute clearance joints

open access: yesInternational Journal of Mechanical System Dynamics, 2021
Due to assembly, wear and manufacturing errors and clearance in the joints are inevitable. When the clearance is introduced into a mechanical system, the impact force in the clearance joint will cause undesirable vibration of the system.
