—High-capacity NAND flash memory can achieve high density storage by using multi-level cells (MLC) to store more than one bit per cell. Although this larger storage capacity is certainly beneficial, the increased density also increases the raw bit error rate (BER), making powerful error correction coding necessary. Traditional flash memories employ simple(More)
—Multiple reads of the same Flash memory cell with distinct word-line voltages provide enhanced precision for LDPC decoding. In this paper, the word-line voltages are optimized by maximizing the mutual information (MI) of the quantized channel. The enhanced precision from a few additional reads allows frame error rate (FER) performance to approach that of(More)
DØ has measured the inclusive production cross section of W and Z bosons in a sample of 13 pb −1 of data collected at the Fermilab Tevatron. The cross sections, multiplied by their leptonic branching fractions, for production in p¯ p collisions at √ s = 1.8 TeV are σ W B(W → eν) = 2.36 ± 0.02 ± 0.08 ± 0.13 nb,
Elimination of tuberculosis (TB) largely depends upon definitive rapid diagnosis and treatment. Widely used diagnostic tests do not qualify for use in a developing country due to lack of either desired accuracy or their cost. In the present study an enzyme-linked immunosorbent assay was used to evaluate the diagnostic potential of an immuno-dominant(More)
We present a measurement of the W boson mass using data collected by the DØ experiment at the Fermilab Tevatron during 1994–1995. We identify W bosons by their decays to eν final states where the electron is detected in a forward calorimeter. We extract the W boson mass, M W , by fitting 3 4 the transverse mass and transverse electron and neutrino momentum(More)
The gauge boson pair production processes W␥, WW, WZ, and Z␥ were studied using p p ¯ collisions corresponding to an integrated luminosity of approximately 14 pb Ϫ1 at a center-of-mass energy of ͱsϭ1.8 TeV. Analysis of W␥ production with subsequent W boson decay to l ␯ (l ϭe,␮) is reported, including a fit to the p T spectrum of the photons which leads to(More)
Mycobacterium tuberculosis (MTB) is the causative agent of pulmonary tuberculosis (PTB), a major health problem that leads to 1.5 million deaths annually. Host genetic factors play a significant role in disease resistance/susceptibility by altering immunity against MTB. Toll-like receptor (TLR) sensors such as TLR2, TLR4, TLR8, and TLR9 are known to play a(More)
This paper investigates the application of low-density parity-check (LDPC) codes to Flash memories. Multiple cell reads with distinct word-line voltages provide limited-precision soft information for the LDPC decoder. The values of the word-line voltages (also called reference voltages) are optimized by maximizing the mutual information (MI) between the(More)
