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 capacity is certainly beneficial, the increased also increases raw error rate (BER), making powerful correction coding necessary. Traditional memories employ simple algebraic codes, such as BCH that correct a fixed, specified number of errors. This paper investigates application low-density parity-check (LDPC) codes which are well known...

Multiple reads of the same Flash memory cell with distinct word-line voltages provide enhanced precision for LDPC decoding. In this paper, are optimized by maximizing mutual information (MI) quantized channel. The from a few additional allows frame error rate (FER) performance to approach that full-precision soft and enables an code significantly outperform BCH code. A constant-ratio constraint provides significant simplification in optimization no noticeable loss performance. For...

Leprosy is a chronic bacterial disease caused by Mycobacterium leprae . patients have been found to defects in T cells activation, which critical the clearance of bacilli. Treg cell suppression mediated inhibitory cytokines such as IL10, IL-35 and TGF-β its frequency higher leprosy patients. Activation overexpression programmed death 1 (PD-1) receptor considered one pathways inhibit T-cell response human leprosy. In current study we address effect PD-1 on Tregs function immuno-suppressive...

Mycobacterium avium subspecies paratuberculosis (MAP) causes Johne's disease in ruminants, a chronic enteritis evocative of human inflammatory bowel disease. In industrialized countries MAP has been cultured from pasteurized milk, compounding the increasing concern that may be zoonotic. The purpose this study was to evaluate commercially available unpasteurized and milk its products for presence viable or DNA an area northern India with population 150 million people.We studied 43 samples (16...

Background. Sub-Saharan African nations have among the highest rates of chronic hepatitis B virus (HBV) infection worldwide, but little is known about HBV in African-born persons United States. Methods. From October 2011 to July 2013, community-based screenings were conducted targeting originating from Africa New York City. Persons identified as currently infected (HBsAg positive) or exposed (HBcAb positive). Results. Overall, 955 screened for HBV; median age was 45 years (interquartile...

The field of Acoustic Event Detection is generally overshadowed by the traditional Automatic Speech Recognition. But our auditory environment made up many sounds other than speech. Most current surveillance systems, diagnostic etc. use video cameras and sensors. acoustic sensors are not used frequently because lack event detection accuracy in case overlapped events. This motivates need for developing a system that able to identify scenes correctly. Researchers have worked on events diverse...

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 either desired accuracy or their cost. In the present study an enzyme-linked immunosorbent assay was evaluate potential immuno-dominant 30/32-kDa mycolyl transferase complex (Ag85 complex) Mycobacterium tuberculosis-specific proteins (ESAT-6 CFP-10) RD1 region. Higher sensitivity (84.1%) with Ag85 observed...

Abstract This paper reports the formation of flower-like hierarchical molybdenum disulfide (MoS 2 ) nanoparticles following a simple one-step hydrothermal process with varying temperatures (200 °C and 220 °C). The as-synthesized particles were examined crystallographically by X-ray diffraction (XRD) method which revealed hexagonal MoS (2H-MoS that crystallite size increased increasing temperature. Surface morphological characteristics investigated field emission scanning electron microscope...

We propose a novel goodness-of-fit detection scheme for spectrum sensing, based on differential entropy in the received observations. The noise distribution is known to deviate from Gaussian many practical communication settings. We, therefore, permit that process follows generalized distribution, which subsumes and Laplacian as special cases. obtain, closed form, of test statistic under null hypothesis compute threshold satisfies constraint probability false alarm. Furthermore, we derive...

Background: Population aging is a worldwide phenomenon. In India, according to the 2001 Census, elderly population (60+ years) accounted for 77 million; however, has crossed 100 million mark Census 2011. Aging results in generalized deterioration of most vital organs and systems, thereby leading lesser effectiveness physiological functions an increase risk factors that leads various diseases.

Background Aminoglycosides are commonly used in tuberculosis treatment and drugs of choice especially for MDR patients. They inhibit protein synthesis susceptible bacteria by interacting with steps translation. Several explanations have been put forward to explain the mechanism aminoglycosides resistance but still our knowledge is fragmentary.
