Staged cooling of a fusion-grade plasma in a tokamak thermal quench
Nuclear Fusion, 2023 In tokamak disruptions where the magnetic connection length becomes comparable to or even shorter than the plasma mean-free-path, parallel transport can dominate the energy loss and the thermal quench of the core plasma goes through four phases (stages ...

Quantum quench from a thermal initial state [PDF]
EPL (Europhysics Letters), 2009 We consider a quantum quench in a system of free bosons, starting from a thermal initial state. As in the case where the system is initially in the ground state, any finite subsystem eventually reaches a stationary thermal state with a momentum-dependent effective temperature.

Nuclear Fusion, 2023 The edge plasma turbulence and transport dynamics, as well as the divertor power loads during the thermal-quench phase of tokamak disruptions, are numerically investigated with BOUT++’s flux-driven six-field electromagnetic turbulence model.

Prethermalization and thermalization of a quenched interacting Luttinger liquid [PDF]
Physical Review A, 2016 We study the relaxation dynamics of interacting, one-dimensional fermions with band curvature after a weak quench in the interaction parameter. After the quench, the system is described by a non-equilibrium initial state, which relaxes towards thermal equilibrium, featuring prethermal behavior on intermediate time and length scales.

Molecular Oncology, EarlyView.Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Thermality from a Rindler quench [PDF]
Classical and Quantum Gravity, 2018 Abstract Ultracold fermionic atoms in an optical lattice, with a sudden position-dependent change (a quench) in the effective dispersion relation, have been proposed by Rodríguez-Laguna et al as an analogue spacetime test of the Unruh effect.

Molecular Oncology, EarlyView.The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

Manipulation of Glassy State in Amorphous Selenium by Low-temperature Internal Friction Measurements [PDF]
Materials Research, 2018 We have studied the thickness and quench-rate dependent internal friction of amorphous selenium (a-Se) thin films deposited at room temperature. The internal friction of a-Se films exhibit a temperature independent plateau below 1 K followed by a broad ...

FEBS Open Bio, EarlyView.The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Thermal Quenching of Thermoluminescence in Quartz [PDF]
Geophysical Journal International, 1975 Summary Studies of the stability and kinetics of the 325 °C thermoluminescence peak in quartz are described which show the occurrence of thermal quenching, the decrease in luminescence efficiency with rise in temperature. This phenomenon causes the ‘initial rise’ method of trap depth determination to give spuriously low results which erroneously ...
