“In search of novel detectors of electromagnetic radiation at terahertz frequencies, field-effect transistors

(FETs) have recently gained much attention. The current literature studies them with respect to the excitation of plasma waves in the two-dimensional channel. Circuit DAPT inhibitor aspects have been taken into account only to a limited degree. In this paper, we focus on embedding silicon FETs in a proper circuitry to optimize their responsivity to terahertz radiation. This includes impedance-matched antenna coupling and amplification of the rectified signal. Special attention is given to the investigation of high-frequency short-circuiting of the gate and drain contacts

by a capacitive shunt, a common approach of high-frequency electronics to induce resistive mixing in transistors. We theoretically study the effect of shunting in the framework of the Dyakonov-Shur plasma-wave theory, with the following key results. In the quasistatic limit, the capacitive shunt induces the longitudinal high-frequency field needed in the FET’s channel for resistive mixing. In the non-quasi-static case, the shunt’s role is taken over by plasma waves. Rectification can then be described as distributed self-mixing in the transistor’s channel. Based on such considerations as well as other circuit-related aspects, we arrive at a rational design for FET-based detectors of terahertz radiation, and implement the first monolithically GDC-0973 MAPK inhibitor integrated 0.65 THz focal-plane array including antennas and amplifiers on a single silicon die. The measured performance data compare well with the theoretical predictions. (C)

“Essential hypertension is frequently associated with hyperuricemia in both adult and pediatric patients. Lowering serum uric acid level may provide greater benefit than simply treating hypertension.

Forty-four adolescents, aged 12-19 years, newly diagnosed as essential hypertension (secondary hypertension was excluded) and previously untreated were randomized (open label trial) to receive CUDC-907 either enalapril or enalapril plus allopurinol in combination. All participants had baseline serum uric acid level a parts per thousand yen5.5 mg/dl.

Baseline mean blood pressure (BP), age and body mass index were similar between the two groups. After 8 weeks’ treatment, BP reduction was greater, percent of treatment group achieving target BP level was greater, and serum uric acid level was lower in the combination treatment group. There were no adverse effects during the course of therapy.

Results suggest that uric acid reduction may be used as adjunctive antihypertensive therapy in hypertensive adolescents with hyperuricemia while closely monitoring for any adverse effect.
