BACKGROUND Current methods for detecting malaria parasites are invasive and associated with poor compliance when repeated sampling is required. New methods to detect and quantify parasites in a less-invasive manner would greatly enhance the potential for longitudinal surveillance in clinical trials. METHODS Saliva, urine, and blood samples from 386 Gambian outpatients with suspected malaria i...

This paper presents the implementation of a generalpurpose programmable vision chip, with a 39×48 SIMD processor-per-pixel array, fabricated in a 0.35μm CMOS technology. The chip employs Analogue Processing Elements to achieve cell density of 410 cells/mm. The array operates at 1.25MHz with power consumption of 12μW/cell and executes low-level image-processing algorithms in real-time. Chip arch...

Production of a vesicular stomatitis virus spike protein G (VSVG)-pseudotyped lentiviral expression vector in HEK293 cells decreased on overexpression of low-density lipoprotein receptor (LDLR) but not that of ICAM1 or TfR1. Reverse transcription-quantitative PCR (RT-qPCR) revealed a reduction in vector RNA as a function of LDLR expression. Decreased syncytium formation suggested diminished sur...

In this paper, we present a fully pipelined LDPC decoder for 802.11n standard that supports variable block sizes and multiple code rates. The proposed architecture utilizes features of Quasi-Cyclic LDPC codes and layered decoding to reduce memory bits and interconnection complexity through efficient utilization of permutation network for forward and backward interconnection routing. Permutation...

Based on the Generalized Distributive Law and the features of FPGAs, this paper proposes a new strategy for implementation of Low-Costing QC-LDPC Decoder on FPGA platform. We get this new strategy from the Generalized Distributive Law, which is proposed to describe the belief propagation on graphs. And using this new strategy a low-costing (2560, 1024) LDPC decoder is implemented on a Xilinx Vi...

The use of spectrally e cient continuous phase modulations for mobile communications may lead to a serious performance degradation of the classical frequency error detectors (FEDs) due to the presence of self-noise. This contribution presents a new statistically e cient frequency estimation algorithm for staggered modulations. The cancellation of the self-noise is accomplished by the use of the...

The LightCycler is a rapid air-heated thermal cycler which incorporates a fluorimeter for the detection and quantification of Polymerase Chain Reaction (PCR) amplified products. It provides real-time cycle-by-cycle analysis of product generation. Amplification occurs in glass capillary tubes. The products are detected using a fluorescent double stranded DNA binding dye or fluorescent probes. Ho...

In this paper, a voltage-current mode controller is proposed to adjust both the input current and DC voltage of a boost-inverter in order to improve the performance of the photovoltaic (PV). The proposed system is based on fuzzy-making-decision predictive voltage-current controller (FPVCC). The simulation results show that in case of using the proposed FPVCC, the input current of a PV array is ...
