Energy is essential for human existence and our future depends on plentiful and accessible sources of energy. The world population is fast growing and the average energy used per capita increases. One of the greatest challenges for human beings is that of ...
Thermonuclear controlled fusion research is a highly active branch of plasma physics. The main goal is the production of energy from the fusion reaction of hydrogen isotope nuclei, the same reaction that powers stars. The most promising present approach ar ...
Single-electron bipolar avalanche transistors (SEBATs) enable current sensing by electron counting at room temperature. Here, differential SEBAT circuits combining the functions of amplification and analog-to-digital (A/D) conversion are proposed and chara ...

This paper addresses the problem of social interaction analysis in competitive meetings, using nonverbal cues. For our study, we made use of ”The Apprentice” reality TV show, which features a competition for a real, highly paid corporate job. Our analysis ...
Intermittent convective transport caused by blobs is universally observed at the edge of laboratory plasmas and it is of great importance for future fusion reactors. We present recent advances in the basic study of blob formation and propagation dynamics a ...
We construct a non-equilibrium steady state and calculate the corresponding current for a mesoscopic Fermi system in the partition-free setting. To this end we study a small sample coupled to a finite number of semi-infinite leads. Initially, the whole sys ...
Intermittent convective transport caused by coherent structures, or blobs, are universally observed in the edge of laboratory plasmas. Besides being of fundamental physics interest, the dynamics of these structures in fusion reactors influence the density ...
A full tokamak discharge simulator has been developed by combining a free-boundary equilibrium evolution code, DINA-CH, and an advanced transport modelling code, CRONOS. The combined tokamak discharge simulator provides a full simulation of a whole tokamak ...
Resonant magnetic perturbation (RMP) and error field correction (EFC) produced by toroidally and poloidally distributed coil systems can be optimized if each coil is powered with an independent power supply. A 3D multi-mode geometry-independent Lagrange me ...
This paper reports on the fabrication and characterization of a pA current and temperature sensing device with ultra-low power consumption based on a Schottky barrier silicon nanowire transistor. Thermionic and trap-assisted tunneling current conduction me ...
