Active Micromachined Integrated Terahertz Circuits [PDF]

International Journal of Infrared and Millimeter Waves, 1999
Schottky barrier diodes have been integrated into on-chip rectangular waveguides. Two novel techniques have been developed to fabricate diodes with posts suitable for integration into waveguides. One technique produces diodes with anode diameters of the order of microns with post heights from 90 to 125 microns and the second technique produces sub ...

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.

A novel single‐phase five‐level hybrid rectifier using two active switches

IET Power Electronics, 2021
A novel single‐phase five‐level rectifier based on two active switches is presented. The proposed novel circuit topology, with two active switches and a split dc‐link, can produce a distinct five‐level voltage with a reduced number of active switches ...

Versatile vector tools for efficient protein screening across multiple expression systems

FEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Analysis of short-circuit transients in the LHC main dipole circuit [PDF]

, 2019
After the occurrence and detection of a short circuit to ground in the LHC main dipole circuit, a fast power abort is triggered and the current in the circuit starts decaying semi-exponentially from a maximum value of 11.85 kA to zero, with a time ...

Compact Impedance Matching Circuit for Wideband Power Transfer in Janus Helmholtz Transducers

Journal of Marine Science and Engineering
The Janus Helmholtz transducer (JHT) is known for high transmission voltage response (TVR) over a wide bandwidth by its dual-resonance characteristics. It is usually required to design matching circuits for wideband power transmission of JHT.

Active‐Only Sinusoidal Oscillator Circuits [PDF]

Active and Passive Electronic Components, 2001
Two new active‐only sinusoidal oscillator circuits are proposed. The first circuit uses one current feedback operational amplifier (CFOA) and four operational transconductance amplifiers (OTAs). The second circuit uses only four OTAs. Without using any external passive elements, voltage (or current) control of the frequency and condition of oscillation,
