The ultimate test of HIV remission is maintenance of undetectable plasma viraemia off antiretroviral therapy. Several studies, both past and recent have explored how common this phenomenon is and what factors predict successful viral control where present. There is no unifying definition of post-treatment control (PTC), in terms of length of time plasma viral load (VL) remains below a certain t...

The strong-field approximation, amended so as to allow for rescattering, is used to calculate high-order above-threshold ionization (ATI) spectra. The single-active-electron binding potential is modelled by a zero-range potential. The emphasis is on enhancements of groups of ATI peaks that occur for sharply defined laser intensities. The enhancements are traced to multiphoton resonance with the...

With the adoption of a globalized and distributed IC design flow, IP piracy, reverse engineering, and counterfeiting threats are becoming more prevalent. Logic obfuscation techniques including logic locking and IC camouflaging have been developed to address these emergent challenges. A major challenge for logic locking and camouflaging techniques is to resist Boolean satisfiability (SAT) based ...

Drugs and surgery can interfere with the biodistribution of radiopharmaceuticals and data about the effect of splenectomy on the metabolism of phytate-Tc-99m are scarce. This study aimed at evaluating the interference of splenectomy on phytate-Tc-99m biodistribution and liver function in rats. The SP group rats (n=6) underwent splenectomy. In group C (control) the animals were not operated on. ...

The SPAn232 virus (SPAnv) was isolated from sentinel mice in the forest of Cotia, São Paulo, Brazil. It was grouped originally as a Cotia virus (CV) sample due to serological cross-reaction with the latter. However, SPAnv presented genetic characteristics that differed from CV and indicated that SPAnv is a member of the vaccinia virus (VV) subgroup. SPAnv showed a HindIII-digested DNA pattern s...

We present intensity-resolved above-threshold ionization (ATI) spectra of xenon using an intensity scanning and deconvolution technique. Experimental data were obtained with laser pulses of 58 fs and a central wavelength of 800 nm from a chirped-pulse amplifier. Applying a deconvolution algorithm, we obtained spectra that have higher contrast and are in excellent agreement with characteristic t...

Synthetic aperture radar provides high-resolution images of the non-moving ground scene, but fails to indicate and position moving objects. A short review of the motioninduced effects occurring in SAR images will open this lecture. Like in special airborne MTI systems, the solution to the SAR MTI problem is to use an array of antennas or subapertures and several receiving channels to cancel the...

Current consumer graphics hardware, like NVIDIA's GeForce 3 and GeForce 4 chipset family or the ATI Radeon 8500 series, offers the possibility of replacing the fixed-function rendering pipeline with user-developed programs, usually referred to as shaders or shader programs. Newer generation cards, like the NVIDIA GeForce FX, ATI Radeon 9700, or cards based on 3Dlabs’ P10 chip, provide an extend...
