An Exploration of Canoeing Action as Therapy for Spinally Injured People

open access: yesAdvances in Electrical and Electronic Engineering, 2004
This paper outlines the design and building of a kayak machine, for use by person with spinal injury. We designed an eddy current brake to apply varying known torques on the system, which determine the power required by the user to run the machine.

Dynamics of aircraft antiskid braking systems [PDF]

open access: yes
A computer study was performed to assess the accuracy of three brake pressure-torque mathematical models. The investigation utilized one main gear wheel, brake, and tire assembly of a McDonnell Douglas DC-9 series 10 airplane. The investigation indicates

Brake Anti-slide Detection and Protection for Metro Vehicles

open access: yes机车电传动, 2015
Based on the weakness analysis of the traditional wheel-slip detect methods such as speed difference and decelerationcriterion, proposals were given for the reference speed calculation and over sensitive caused by deceleration-criterion. At the same time,

Multi‐omic profiling reveals immune cell priming signature linked to lupus prognosis

open access: yesArthritis &Rheumatology, Accepted Article.
Objective Systemic lupus erythematosus (SLE) is a multi‐organ disease with widespread immune dysregulation and significant unmet clinical need. Blood‐based gene expression studies have advanced our understanding of SLE pathogenesis but may overlook critical tissue‐specific mechanisms that drive disease heterogeneity and progression.

Intravenous lanadelumab for the treatment of moderately ill COVID‐19 patients

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Aims Kallikrein‐kinin system (KKS) dysregulation is hypothesized to play a pathogenetic role in COVID‐19‐associated pulmonary oedema. To investigate the efficacy and safety of intravenous lanadelumab, a monoclonal antibody that inhibits plasma kallikrein, in COVID‐19, we conducted a phase 2, open‐label, randomized‐controlled, proof‐of‐concept ...

Study of Brake Shoes Parameters on Brake Squeal Propensity Based on Complex Eigenvalue Method

open access: yes机车电传动, 2015
A finite element model of a pad-wheel brake device was established using ABAQUS to predict the brake squeal noise. The influence of friction coefficient between the friction body and the tread, Young’s modulus of the friction body and the back plate on ...
