Substrate stiffness and VE-cadherin mechano-transduction coordinate to regulate endothelial monolayer integrity. [PDF]

open access: yes, 2017
The vascular endothelium is subject to diverse mechanical cues that regulate vascular endothelial barrier function. In addition to rigidity sensing through integrin adhesions, mechanical perturbations such as changes in fluid shear stress can also ...

Melt Electrowriting High Resolution Poly(ethylene‐co‐vinyl acetate) Scaffolds for Soft Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This work pioneers melt electrowriting (MEW) of polyethylene vinyl acetate (PEVA) to fabricate ultra‐compliant, high‐resolution scaffolds. By integrating microscale precision with soft tissue‐like biomechanics, PEVA overcomes stiffness‐driven limitations of conventional MEW polymers, establishing a mechanically biomimetic platform for soft tissue ...

Finite element analysis of the critical stress for bone resorption around the orthodontic anchoring screw in midpalatal area during distalization of the maxillary dental arch

open access: yesClinical and Investigative Orthodontics
Purpose This study aimed to determine the conditions for reaching critical stress that causes bone resorption around the orthodontic anchoring screw (screw) during maxillary dental arch distalization using a palatal lever arm (PLA) through finite element

A modified Oster-Murray-Harris mechanical model of morphogenesis [PDF]

open access: yes, 2013
There are two main modeling paradigms for biological pattern formation in developmental biology: chemical prepattern models and cell aggregation models. This paper focuses on an example of a cell aggregation model, the mechanical model developed by Oster,

Common Signatures of Altered Gene Regulation and Invasiveness of Different Breast Cancer Cell Lines after Matrix Interface Crossing

open access: yesAdvanced Healthcare Materials, EarlyView.
Interface transmigration reprograms triple‐negative breast cancer cells, triggering a shared switch toward more aggressive and invasive phenotypes. Using a collagen I interface model, this study identifies shared transcriptional changes involving proliferation, chromatin remodeling, and DNA repair pathways.

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

open access: yesAdvanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Research on Hierarchical Collaborative Control of Dual-Axis Drive Hybrid Electric Tractor for Hill and Mountain Terrain Considering Traction Efficiency and Energy Consumption Economy

open access: yesWorld Electric Vehicle Journal
Hybrid tractors operating in hilly terrain often suffer from reduced overall performance due to unregulated slip rate variations. To address this issue, this paper proposes a hierarchical cooperative control strategy that jointly optimizes traction ...

Application of damage mechanics in percussive drilling modelling [PDF]

open access: yes, 2005
A stationary-periodic quasi-static model of rock percussive deep drilling is introduced. First, an auxiliary problem of stationary indentation of a rigid indentor is considered.

Design and Testing of a Structural Monitoring System in an Almería-Type Tensioned Structure Greenhouse [PDF]

open access: yes, 2020
Greenhouse cultivation has gained a special importance in recent years and become the basis of the economy in south-eastern Spain. The structures used are light and, due to weather events, often collapse completely or partially, which has generated ...

Finite element analysis of footwear and ground interaction [PDF]

open access: yes, 2005
Military boots are designed to prevent the soft tissue and skeletal structure of the feet from damage under heavy usage. Good slip-resistant tread patterns of the outer-sole are vital to minimise the risk or severity of slipping under demanding ...
