Development Characteristics and Rapid Evaluation of High-steep Unstable Rock in Ya’an—Changdu Section of Sichuan—Tibet Railway

open access: yes工程科学与技术, 2022
Sichuan—Tibet railway is in the topographic crossing zone from the Sichuan basin to Qinghai Tibet Plateau. Regional characteristic geological factors such as active structure, valley unloading and freeze-thaw weathering along the line have strong control

On the stability of piecewise polynomial collocation methods for solving weakly singular integral equations of the second kind

open access: yesMathematical Modelling and Analysis, 2008
Piecewise polynomial collocation methods on special nonuniform grids are efficient methods for solving weakly singular Fredholm and Volterra integral equations but there is a widespread belief that those methods are numerically unstable in the case of ...

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.

Impact of flux jumps in future colliders

open access: yesPhysical Review Accelerators and Beams, 2020
Type-II superconductors, like the Nb_{3}Sn used in the new HL–LHC quadrupole triplet and 11 T dipoles or FCC dipoles, are known to show an unstable behavior during magnetic-field ramps.

Translating whole‐genome doubling into precision medicine in cancer

open access: yesMolecular 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)

Cellular automaton simulation of counter flow with paired pedestrians [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2011
Knowledge on pedestrian behavior is the basis to build decision support system for crowd evacuation management in emergency. In this paper, the impact of paired walking behavior on pedestrian counter flow in a channel is studied.

On the Quantum Deviations from Einstein Dilation of Unstable Quanton* Decay Evolution and Lifetimes [PDF]

open access: yes, 2011
For over a decade several workers have argued for the existence of quantum deviations from the classical, Einstein dilation of the decay evolution of moving or Lorentz boosted unstable particles.

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Depth Dependence and Keyhole Stability at Threshold, for Different Laser Welding Regimes

open access: yesApplied Sciences, 2020
Depending of the laser operating parameters, several characteristic regimes of laser welding can be observed. At low welding speeds, the aspect ratio of the keyhole can be rather large with a rather vertical cylindrical shape, whereas at high welding ...
