This work presents an active balanced sub-harmonic mixer (SHM) using InP double heterojunction bipolar transistor technology (DHBT) for Q-band applications. A miniature spiral type Marchand balun with five added capacitances for improved control of amplitude and phase balance is integrated with the SHM. The measured results for the SHM demonstrates a conversion gain of 1.2 dB at an RF frequency...

INTRODUCTION We analyzed phase 3 trial data of ombitasvir/paritaprevir/ritonavir and dasabuvir (3D) ± ribavirin (RBV) in genotype 1 chronic hepatitis C patients to investigate the impact of 3D ± RBV on renal, cardiovascular and metabolic extrahepatic manifestations (EHMs), including persistency 52 weeks post treatment and differential impact by EHM disease severity. METHODS Estimated glomerul...

Emergent Hadron Mass (EHM) is a mechanism capable of explaining both the unnaturally small (pion) and large (proton) masses hadrons if not origin confinement, then intimately connected with it. Even though modern formulation EHM has only recently been completed, it rapidly becoming fundamental focus for future experimental efforts aimed at understanding strong force within Standard Model. Using...

Upon penetration of the host cell wall, the powdery mildew fungus develops a feeding structure named the haustorium in the invaded host cell. Concomitant with haustorial biogenesis, the extrahaustorial membrane (EHM) is formed to separate the haustorium from the host cell cytoplasm. The Arabidopsis resistance protein RPW8.2 is specifically targeted to the EHM where it activates haustorium-targe...

A coplanar millimeter wave doubler MMIC covering the entire G-band was developed. Based on a 50 nm metamorphic HEMT technology, the circuit demonstrates an output power of more than –12 dBm between 150and 220 GHz for an input power of 0 dBm. By increasing the input power to 12 dBm an output power exceeding 0 dBm was obtained in the frequency range between 180and 220 GHz. Good fundamental reject...

In recent years, the CMRC filter has been an attractive candidate for use in mixer and frequency multiplier circuits to improve the performance due to its low-insertion loss, sharp rejection, shorter size and wider stop-band. However, complex structures, too much variables and inefficient design method hindered its widespread use. In this study, we report on the application of the implicit spac...

This paper deals with Schottky and Heterostructure Barrier devices fabricated for planar integration in a 560 GHz Subharmonic Mixer (SHM). Taking advantage of an InP-based technology, two barrier types, metal/InGaAs and metal/InAlAs/InGaAs respectively, have been investigated. The design was carried out by means of self-consistent quantum calculations and the fabrication involved submicron Tsha...

This paper describes sub-harmonic mixer designed in 0.18 μm CMOS process and intended for use in low-power IEEE 802.15.4-compliant 2.4 GHz transceiver. Device addresses the following issues of the direct conversion architecture: flicker-noise, LO leakage and oscillator pulling.

An infection with Equine herpesvirus type 1 (EHV-1), officially and by convention now called EQUID Herpesvirus, is the cause for Equine herpesvirus-associated Myeloencephalopathy or EHM. In 2008 the USDA declared this syndrome an ‘emerging disease’ among horse populations in the U.S.A., which indicates that EHM is perceived as an expanding problem that is observed more frequently when compared ...

This paper discusses issues, possibilities and existing approaches for fitting an exception handling mechanism (EHM) in CSP-based process-oriented software architectures. After giving a survey on properties desired for a concurrent EHM, specific problems and a few principal ideas for including exception handling facilities in CSP-designs are discussed. As one of the CSP-based frameworks for con...
