FTC Bureau of Economics working papers are preliminary materials circulated to stimulate discussion and critical comment. The analyses and conclusions set forth are those of the authors and do not necessarily reflect the views of other members of the Bureau of Economics, other Commission staff, or the Commission itself. Upon request, single copies of the paper will be provided. References in pu...
After adaptation to cyclic illumination (14:10 light-dark cycle; intensity = 1.4 log ftc) male albino rats were exposed to brighter light (2.15 log ftc) seven hours daily for 25 days. The extent of retinal damage was determined histologically. Daily exposure to bright light in the morning produced greater photoreceptor loss than daily afternoon exposure. Severe retinal damage was partially prev...
This paper proposes a new discrete fuzzy-tuning current-vector control (FTC) scheme for three-phase pulsewidth modulation (PWM) inverters. The proposed current control scheme can achieve fast transient responses and, at the same time, have very low total harmonic distortion in output current during steady-state operation. The proposed FTC scheme generates quasi-optimum PWM patterns by using a c...
In this paper we are explosively the fundamental theory of radar system modules STC (sensitivity time control) or sea clutter and FTC (fast time constant) or rain clutter. The STC and FTC are commonly used to some clutter. The radar signal is widely used for weather forecast, air port traffic control, military and fire control. The system implements radar processing procedures in real time mode...
The HIV/AIDS epidemic, which was first reported on in 1981, progressed in just 10 years to a disease afflicting 10 million people worldwide including 1 million in the US. In 1987, AZT was approved for treating HIV/AIDS. Unfortunately, its clinical usefullness was severly limited by associated toxicities and the emergence of resistance. Three other drugs that were approved in the early 1990s suf...
This paper discusses the finite time consensus (FTC) issue of nonlinear heterogeneous multi-agent systems (HMASs) by combining integral sliding-mode control (SMC), event-triggered (ETC) and pinning methods. The SMC is constructed separately for first-order second-order agents to assure that system not interfered nonlinearities disturbances when state trajectory moves on sliding surface. To stim...
The proto-oncogene PIK3CA has been well studied for its activating mutations and genomic amplifications but not single nucleotide polymorphism (SNP) in thyroid cancer. We investigated SNP rs17849071 (minor allele G and major allele T) in PIK3CA in thyroid tumors in 503 subjects by PCR and sequencing of a region of intron 9 carrying this SNP. This SNP was found in both normal and thyroid tumor t...
28 32 24 10 Viral Load Diagnostics Superbugs Immunotherapy Occupational Exposure HIV Clinical update STRIBILD is indicated as a complete single-tablet regimen for the treatment of HIV-1 infection in adults who are antiretroviral treatment-naïve. 1 • STRIBILD achieves strong effi cacy with an overall rapid reduction in viral load 3,4 – Noninferior effi cacy at week 48 • 90% of subjects taking ST...
UNLABELLED Data are limited on the safety and effectiveness of oral antivirals other than lamivudine and adefovir dipivoxil for treatment of chronic hepatitis B (CHB) in patients with decompensated liver disease. This Phase 2, double-blind study randomized 112 patients with CHB and decompensated liver disease to receive either tenofovir disoproxil fumarate (TDF; n = 45), emtricitabine (FTC)/TDF...
Resistant variants of human immunodeficiency virus type 1 (HIV-1) have been selected by limited passage in MT4 cells of both wild-type and 3'-azido-3'-deoxythymidine (AZT, zidovudine)-resistant strains with the nucleoside analogues (-)-2'-deoxy-3'-thiacytidine (3TC) and (-)-2'-deoxy-5-fluoro-3'-thiacytidine (FTC). Virus variants selected independently were crossresistant to both inhibitors. Thi...
