Numerical analysis of the radio-frequency single-electron transistor operation
, 2003 We have analyzed numerically the response and noise-limited charge sensitivity of a radio-frequency single-electron transistor (RF-SET) in a non-superconducting state using the orthodox theory. In particular, we have studied the performance dependence on

FEBS Open Bio, EarlyView.ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

Dapagliflozin prevents methylglyoxal‐induced retinal cell death in ARPE‐19 cells
FEBS Open Bio, EarlyView.Diabetic macular oedema is a diabetes complication of the eye, which may lead to permanent blindness. ARPE‐19 are human retinal cells used to study retinal diseases and potential therapeutics. Methylglyoxal is a compound increased in uncontrolled diabetes due to elevated blood glucose.

On-Chip Matching Networks for Radio-Frequency Single-Electron-Transistors
, 2007 In this letter, we describe operation of a radio-frequency superconducting single electron transistor (RF-SSET) with an on-chip superconducting LC matching network consisting of a spiral inductor L and its capacitance to ground.

Double-Tuned Impedance Matching [PDF]
IEEE Antennas and Propagation Magazine, 2012 In the 1940s, Harold Wheeler developed the principles of double-tuned impedance matching in a simple form. These relationships are not well known. They are very useful for the antenna designer in providing a structured approach to obtain near-maximum bandwidth for narrowband and moderate-band antennas with a specified VSWR limit, using a practical ...

PARP inhibitors induce a senescence phenotype in non‐small cell lung carcinoma cell lines
FEBS Open Bio, EarlyView.Talazoparib is the most potent inducer of senescence among different PARP1 inhibitors in human NSCLC cells. In the absence of PARP, no senescence phenotype was observed, demonstrating that PARP1 is necessary for the induction of senescence by this inhibitor.
