Time-dependent deformation and fracture evolution around underground excavations

open access: yesGeomatics, Natural Hazards & Risk, 2020
A numerical time-dependent deformation model of rock by incorporating the stress corrosion model into a three-dimensional discrete element code was established to investigate time-dependent deformation and fracture evolution of surrounding rock around ...

4-nitroquinoline 1-oxide induces immune cells death to onset early immunosuppression during oral squamous cell carcinoma development

open access: yesFrontiers in Immunology, 2023
4-Nitroquinoline N-oxide (4-NQO) and its derivatives react with genomic DNA to form stable quinolone monoadducts, which are highly mutagenic and genotoxic.

Review of unstable falling of roof rock blocks under dynamic disturbance

open access: yes工程科学学报, 2023
Roof caving has been the main threat to the safety of underground mining, in which the caving of roof rock blocks is particularly concerning. The secondary structural planes of surrounding rocks around underground excavations, such as roadways and stopes,

Targeting ATR and Chk1 kinases for cancer treatment: A new model for new (and old) drugs

open access: yesMolecular Oncology, 2011
Trying to kill cancer cells by generating DNA damage is by no means a new idea. Radiotherapy and genotoxic drugs are routinely used in cancer therapy.

Transition from Spin Dewetting to continuous film in spin coating of Liquid Crystal 5CB

open access: yesScientific Reports, 2018
Spin dewetting refers to spontaneous rupture of the dispensed solution layer during spin coating, resulting in isolated but periodic, regular sized domains of the solute and is pre-dominant when the solute concentration (C n ) is very low.

Subtalar instability

open access: yesJournal of Orthopaedic Surgery, 2023
Subtalar instability is a confusing yet important condition in patients with lateral ankle instability. The author will explore subtalar kinematics, and how they are closely related to the joint stability of the subtalar joint, both with respect to its intrinsic ligaments and its extrinsic ligaments.
