Linkage and Cam Design with MechDev based on Non-Uniform Rational B-Splines

open access: yesMachines, 2020
Several software products exist in order to support engineers during the mechanism design process. The software “Mechanism Developer” (abbr. MechDev) is one of these products. MechDev provides many functionalities concerning the kinematic and

Alignment positioning mechanism [PDF]

open access: yes, 1991
An alignment positioning mechanism for correcting and compensating for misalignment of structures to be coupled is disclosed. The mechanism comprises a power screw with a base portion and a threaded shank portion.

Gravitational Higgs Mechanism

open access: yes, 2000
We discuss the gravitational Higgs mechanism in domain wall background solutions that arise in the theory of 5-dimensional Einstein-Hilbert gravity coupled to a scalar field with a non-trivial potential. The scalar fluctuations in such backgrounds can be

Germline TP53 Mutations Causing Diamond–Blackfan Anemia: A French Report

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Diamond–Blackfan anemia is a rare congenital erythroblastopenia typically caused by mutations in ribosomal protein genes. Recently, gain‐of‐function mutations in TP53 have been identified as a novel cause of Diamond–Blackfan anemia. We report two French patients who both harbored a heterozygous TP53 deletion (NM_000546.5: c.1077delA; p ...

Structural Design and Simulation of Passive Low Gravity Compensation for the Deployable Arm in the Device of Drilling and Collecting Lunar Soil

open access: yesMATEC Web of Conferences, 2015
As an important constituent part of the sampling device for lunar soil drilling, the deployable arm can help transfer the samples and avoid stretching. According to the ground experimental research requirements for deployable arm, this paper proposed a ...

Double Froggatt--Nielsen Mechanism

open access: yes, 2016
We present a doubly parametric extension of the standard Froggatt--Nielsen (FN) mechanism. As is well known, mass matrices of the up- and down-type quark sectors and the charged lepton sector in the standard model can be parametrized well by a parameter $

Dynamic Modeling and Analysis of Rigid-Flexible Coupled Unfolding Mechanisms Under Transient Actuation

open access: yesApplied Sciences
Transient mechanisms are increasingly applied in fields such as high-speed aircraft, super high-speed trains, and underwater robots. However, in high-speed motion, large inertial forces are inevitably generated, which can easily lead to elastic ...

Higgs Mechanism for Gravitons

open access: yes, 2010
Just like the vector gauge bosons in the gauge theories, it is now known that gravitons acquire mass in the process of spontaneous symmetry breaking of diffeomorphisms through the condensation of scalar fields.

The Role of Invasive Procedures in the Treatment of Complicated Gastrointestinal Graft‐Versus‐Host Disease in Pediatric Patients

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Gastrointestinal graft‐versus‐host disease (GI GVHD) following hematopoietic stem cell transplant is typically managed with medical therapy, but surgery and angioembolization may be warranted in selected cases with life‐threatening complications.
