Normalized-constrained approach for joint clearance design of deployable overconstrained Myard 5R mechanism

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2015
This paper proposes a normalized-constrained approach for the joint clearance design of deployable overconstrained Myard 5R mechanism. Firstly, the overconstrained mobility characteristic of Myard 5R mechanism is analyzed, we show that the dimensional ...

How phagocytic cells kill bacteria: Lessons from a professional killer

open access: yesFEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

NUMERICAL CALCULUS REGARDING THE MOTION BEHAVIOUR [PDF]

open access: yesFiabilitate şi Durabilitate, 2012
The kinematic links motion is influenced mostly by the clearance size from the joint and the number of joints with clearance. The presented paper studies a particular kinematic chain as physical pendulum with clearance.

Identification of (20R)‐protopanaxadiol from Panax ginseng as a novel anti‐SARS‐CoV‐2 compound

open access: yesFEBS Open Bio, EarlyView.
We established a noninfectious BAC‐based SARS‐CoV‐2 replicon that enables antiviral screening under BSL‐2 conditions. Using this platform, we screened 373 food‐derived compounds and identified (20R)‐protopanaxadiol from Panax ginseng as a novel inhibitor of SARS‐CoV‐2 RNA replication, highlighting the value of safe replicon systems for antiviral ...

Dynamics behavior analysis of spatial parallel coordinate measuring mechanism with spherical clearance joints

open access: yesMechanics & Industry
A universal dynamics modeling and analysis method applied for spatial parallel coordinate measuring mechanism (SPCMM) is proposed. The influence of spherical clearance joints on the accuracy of SPCMM cannot be ignored, it is necessary to study the ...

Hertz Model Based Contact Modeling for Joints with Clearance

open access: yesMATEC Web of Conferences, 2018
This paper presents the techniques of contact modeling for revolute joints in flexible multibody systems, in which the dry clearance revolute joints have been coupled with the flexibility of connected bodies.

From patient advocacy to patient‐driven research: Building active partnerships beginning at the bench to reach the bedside

open access: yesFEBS Open Bio, EarlyView.
Research is strongest when conducted alongside patients, not just about them. Patient research organizations help integrate patient perspectives into research priorities, study design, and scientific meetings, leading to meaningful patient outcomes and development of relevant therapies.

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

open access: yesFEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

A Study on the strength of the Bolted Joint & Pin Joint with Hole Clearance

open access: yesJournal of The Korean Society for Composite Materials, 2012
With the wide application of fiber-reinforced composite material in aero-structures and mechanical parts, composite joint have become a very important research area because they are often the weakest sites in composite structures. In this paper, the failure strengths of the bolted joint and pin joint which have variable hole clearance were evaluated ...

3D Revolute Joint with Clearance in Multibody Systems [PDF]

open access: yes, 2017
The aim of this paper is to understand the influence of radial and axial clearance in the revolute joints on the overall performance of a circuit breaker. A circuit breaker mechanism is made of seven links, seven revolute joints with clearance in both radial and axial direction, four unilateral contacts with friction, and it has forty-two degrees of ...
