Active mixers operating at 23 GHz are designed and fabricated in SiGe technology. An integrated diode linearizer is used to improve the linearity of the mixer. Measurement and simulation show excellent agreement. Typically, 10 dB double-sideband noise figure, 10 dBm IIP3 and 2 dB conversion gain are measured, featuring low noise and high linearity in a same design.

This was a retrospective cohort study using routine health care data collected between April 1998 and October 2011 from ∼350 U.K. primary care practices contributing to the Clinical Practice Research Datalink (CPRD). Participants comprised 79,966 patients aged between 35 and 85 years (388,269 person-years) with 4,984 cardiovascular events. Four outcomes were evaluated: first diagnosis of corona...

Methotrexate (MTX) is the cornerstone of chemotherapy for primary central nervous system lymphoma, yet how the bloodbrain barrier (BBB) efflux transporters ABCG2 and ABCC4 influence the required high-dose therapy is unknown. To evaluate their role, we used four mouse strains, C57BL/6 (wild-type; WT), Abcg2, Abcc4, and Abcg2;Abcc4 (double knockout; DKO) to conduct brain microdialysis studies aft...

Distributed computing often involves a set of n processes arriving at a consensus/agreement on some bit v, in a de-centralized fashion. The problem is particularly interesting in the presence of Byzantine failures, i.e., an adversary may adaptively corrupt upto t among these n processes and cause them to behave arbitrarily in the consensus protocol. To elaborate, these processes may either comp...

Coeliac disease is a permanent inflammatory disorder of the small bowel affecting approximately 1% of the population. The only effective treatment that exists is exclusion of gluten from the diet. The present paper aims to review the literature as to whether oats are safe to eat for people with coeliac disease. Much data exist on the restrictive nature that adhering to a gluten-free diet impose...

DSRC provides high speed radio link between Road Side Equipment and On-Board Equipment within the narrow communication area. In this paper, a 5.8 GHz down-conversion mixer for DSRC communication system is designed and fabricated using 0.8 m SiGe HBT process technology and RF/LO matching circuits, RF/LO input balun circuits and IF output balun circuit are all integrated on chip. The measured per...
