Orientational Capability Analysis of a 2UPR-SPR Parallel Manipulator
Jixie chuandong, 2019 The parallel module of Exechon machine tool is developed based on the 3 degree-of-freedom (DOF) 2UPR-SPR mechanism, which is a parallel spindle head with two rotational (orientational) DOFs and one translational DOF.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
Molecular Oncology, EarlyView.This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Jixie chuandong, 2008 At singularities, the parallel manipulator will have more than one the motion trends. So the parallel manipulator will lose control. Based on the bifurcation characteristics of a parallel manipulator at singularities, a new method to estimate the losing ...

Molecular Oncology, EarlyView.Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Molecular Oncology, EarlyView.Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Optimization of 3-DOF parallel motion devices for low-cost vehicle simulators
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Motion generation systems are becoming increasingly important in certain Virtual Reality (VR) applications, such as vehicle simulators. This paper deals with the analysis of the Inverse Kinematics (IK) and the reachable workspace of a three-degrees-of ...

A Framework to Illustrate Kinematic Behavior of Mechanisms by Haptic Feedback [PDF]
, 2006 The kinematic properties of mechanisms are well known by the researchers and teachers. The theory based on the study of Jacobian matrices allows us to explain, for example, the singular configuration.

RIPK4 function interferes with melanoma cell adhesion and metastasis
Molecular Oncology, EarlyView.RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.
