Contact formation mechanism between squeezed crystalline solids
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The mechanism was proposed and experimentally approved for the final stage of the high temperature contact formation after generation of closed pores in the contact plane. The mechanism is that the pores being healed by the dislocation-diffusion mechanism form assemblages of vacancy type prismatic dislocation loops which ...

Solid viscoelasticity in contact mechanics and elastohydrodynamic lubrication
, 2022 Driven by the urgent need for transition to new sustainable technology in terms of use of resources and generated waste products, optimal efficiency is of crucial importance. Energy losses at any scale in machines of old (transitional) and new technology and processes need be minimized and performance and service life maximized.

Translating whole‐genome doubling into precision medicine in cancer
Molecular Oncology, EarlyView.Whole‐genome doubling creates a WGD‐positive tumor state characterized by persistent chromosomal instability, karyotypic diversification, and cellular stress. These same biological pressures drive aggressive tumor evolution while exposing therapeutic vulnerabilities, providing a rationale for WGD‐informed precision medicine. Whole‐genome doubling (WGD)
