An improved method for obtaining a normalized junction temperature for semiconductors: A concept [PDF]

open access: yes, 1973
Failure rate for given semiconductor device is simply determined by reading value of normalized junction temperature from printout for any given combination of ambient temperature, stress ratio, and maximum rated junction temperature, and obtaining ...

Anomalous temperature dependence of the supercurrent through a chaotic Josephson junction [PDF]

open access: yes, 1996
We calculate the supercurrent through a Josephson junction consisting of a phase-coherent metal particle (quantum dot), weakly coupled to two superconductors.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Competition between electronic cooling and Andreev dissipation in a superconducting micro-cooler [PDF]

open access: yes, 2009
We discuss very low temperature experiments on superconducting micro-coolers made of a double Normal metal - Insulator - Superconductor junction. We investigate with a high resolution the differential conductance of the micro-cooler as well as of ...

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

Research on Equivalent Circuit Model of HVDC Valve and Calculation of Thyristor Junction Temperature

open access: yesActive and Passive Electronic Components
For the difference of thyristor junction temperature at all levels in the transducer valve assembly in the series water circuit, an equivalent model of thyristor junction temperature calculation for the valve assembly is established, and PLECS simulation

Josephson current noise above Tc in superconducting tunnel junctions

open access: yes, 2008
Tunnel junction between two superconductors is considered in the vicinity of the critical temperature. Superconductive fluctuations above Tc give rise to the noise of the ac Josephson current although the current itself is zero in average. As a result of

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Junction-temperature measurement of IMPATT diodes

open access: yesElectronics Letters, 1972
The breakdown voltage VB of an IMPATT diode is a function of the junction temperature. Pulse techniques are applied to measure VB directly during actual operation, thus giving the temperature within an accuracy of a few per cent. The method also provides a display of 'space-charge resistance at the operating temperature.
