Acid ceramidase promotes drug resistance in acute myeloid leukemia through NF-κB-dependent P-glycoprotein upregulation

Journal of Lipid Research, 2019
Acute myeloid leukemia (AML) is the most common acute leukemia in adults. More than half of older AML patients fail to respond to cytotoxic chemotherapy, and most responders relapse with drug-resistant disease.

Simulation of Dynamic Resistance and Total Loss of HTS CORC Cables

IEEE Access, 2023
In some high temperature superconducting (HTS) applications, HTS coated conductors carry DC current under external AC magnetic fields. Dynamic resistance occurs when the amplitude of the magnetic field is greater than the threshold magnetic field of the ...

Dc and ac behaviour of a normal joint in a superconducting cable [PDF]

, 1984
The application of joints which can be disassembled is studied within the framework of the development of high current (25 kA), high power (0.5 kW) cryogenic current supplies (flux pumps).1,2 The behaviour of a scale model with currents up to 5 kA will ...

Calculation of the Inductance and Resistance Matrices of Medium-Frequency Transformers

IEEE Open Journal of Power Electronics
Due to the ever-increasing switching speeds of wide band gap (WBG) devices, the high-frequency behavior of magnetic components, such as medium-frequency transformers, is becoming increasingly significant. To describe this complex high-frequency behavior,
