On the association between microhardness, corrosion resistance and microstructure of probeless friction stir spot welded Al–Li joint

open access: yesJournal of Materials Research and Technology, 2021
The precipitation behavior and development of grain structure have been investigated to reveal their association with the microhardness and corrosion resistance of probeless friction stir spot welded (P-FSSW) joint of an Al–Li alloy.

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.

TIG Wire and Arc Additive Manufacturing of 5A06 Aluminum Alloy

open access: yesCailiao gongcheng, 2017
Wire and arc additive manufacturing(WAAM) was investigated by tungsten inert gas arc welding method(TIG), in which φ1.2mm filler wire of aluminum alloy 5A06(Al-6Mg-Mn-Si) was selected as deposition metal.

Spatial Frictions [PDF]

open access: yesSSRN Electronic Journal, 2013
The world is replete with spatial frictions. Shipping goods across cities entails trade frictions. Commuting within cities causes urban frictions. How important are these frictions in shaping the spatial economy? We develop and quantify a multi-city general equilibrium model to address this question at three different levels: Do spatial frictions ...

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

open access: yesMolecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Influence of Chemical Heterogeneity and Third Body on Adhesive Strength: Experiment and Simulation

open access: yesFrontiers in Mechanical Engineering, 2021
We investigate experimentally and numerically the influence of chemical heterogeneity and of third-body particles on adhesive contact. Chemical heterogeneity is generated by chemical treatment of the contacting bodies changing locally the surface energy.

Mutant p53R273H disrupts PDPK1 homodimerization and contributes to PDPK1 activation

open access: yesMolecular Oncology, EarlyView.
How mutant p53R273H drives AKT signaling is unclear. We show that p53R273H, but not wild‐type, directly binds PDPK1 via a mutation‐dependent conformational change. This interaction disrupts inhibitory PDPK1 homodimerization and enhances AKT phosphorylation.

Shock isolation systems incorporating Coulomb friction

open access: yes, 2012
This study investigates a novel approach to the problem of shock isolation. The questions considered are whether friction produces a better performance in terms of reduced response during a shock compared to viscous damping and a lower residual response ...

Interfacial microstructure evolution and formation process of the joints prepared by diffusion bonding on DD6 nickel-based single crystal superalloy

open access: yesJournal of Materials Research and Technology, 2020
Nickel-based single crystal superalloy DD6 was diffusion bonded in vacuum at 1170 °C under 55 MPa for 2–6 h. Two processes, direct bonding and bonding with interlayer, were designed for comparison.
