Contact Model of Revolute Joint with Clearance Based on Fractal Theory

open access: yesChinese Journal of Mechanical Engineering, 2018
The contact stiffness of a mechanical bonding surface is an important parameter in determining the normal and radial contact force. To improve the calculation accuracy of the contact force model, the surface roughness of the bonding surface and the ...

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Open-loop position control of a polymer cable–driven parallel robot via a viscoelastic cable model for high payload workspaces

open access: yesAdvances in Mechanical Engineering, 2017
A polymer cable–driven parallel robot has a wide range of potential industrial applications by virtue of its light actuator dynamics, high payload capability, and large workspace. However, due to a viscoelastic behavior of polymer cable and difficulty in

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

open access: yesMolecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

Development of user-customized online teaching technology based on GPT, enhanced by generative AI-based motion recognition

open access: yesScientific Reports
This paper addresses current issues in existing joint tracking and motion recognition algorithms for Human Pose Estimation. It proposes a solution using the Numerical Discriminator Generative Adversarial Network (ND_GAN) to improve the performance of ...

Extending Driving Vision Based on Image Mosaic Technique

open access: yesMATEC Web of Conferences, 2017
Car cameras have been used extensively to assist driving by make driving visible. However, due to the limitation of the Angle of View (AoV), the dead zone still exists, which is a primary origin of car accidents.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Topological Map Construction Based on Region Dynamic Growing and Map Representation Method

open access: yesApplied Sciences, 2019
In the human⁻machine interactive scene of the service robot, obstacle information and destination information are both required, and both kinds of information need to be saved and used at the same time.

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

open access: yesFEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.
