background: gastric cancer (gc) is the most common gastrointestinal cancer in iran. helicobacter pylori (h. pylori) accounts as one of the main risk factors for gastric non-cardia cancer (gncc). it is suggested that high serum selenium level may have a protective role in gncc. in this cross-sectional study, we determined the serum se level and the status of h. pylori infection in two population...

Estimation of the long-memory parameter from log-periodogram (LP) regression, due to Geweke and Porter-Hudak (GPH), is a simple frequently used method semi-parametric estimation. However, LP estimator suffers finite sample bias that increases with dependency in short-run component spectral density. More recently, Arteche Orbe (2009a, 2009b), context GPH estimator, suggested promising bootstrap ...

A sound field reproduction method is proposed that uses blind source separation and a head-related transfer function. In the proposed system, multichannel acoustic signals captured at distant microphones are decomposed to a set of location/signal pairs of virtual sound sources based on frequency-domain independent component analysis. After estimating the locations and the signals of the virtual...

FDBG (short for Finite domain DeBuGger) is a tool addressing the problems of debugging nite domain (FD) constraint programs. Implemented as a SICStus Prolog library, it allows CLP(FD) programmers to trace FD variable domain changes. FDBG is capable of detecting the wake-up of constraints as well as the steps of labeling, and it reports the e ects of these events on the variables. The simplest w...

Lazy clause generation is a powerful hybrid approach to combinatorial optimization that combines features from SAT solving and finite domain (FD) propagation. In lazy clause generation finite domain propagators are considered as clause generators that create a SAT description of their behaviour for a SAT solver. The ability of the SAT solver to explain and record failure and perform conflict di...

two parallel needle moisture sensors has been widely used in Soil moisture detection equipment, for example, frequency domain (FD), time domain reflectometry (TDR) and standing wave ratio (SWR) measurement. The design of probe‘s port impedance is key technology parameters to soil moisture sensor. In this study, according to the relationships between the length and impedance characteristics of t...

In this article, a novel digital predistortion (DPD) solution for fully multiple-input–multiple-output (MIMO) transmitters (TXs) is proposed. Opposed to classical DPD solutions that operate at TX chain or antenna level, the proposed operates stream beam and hence, its complexity proportional number of spatially multiplexed streams users rather than antennas. addition, beam-level in frequency do...

This paper presents FD-MCP, a finite domain modeling language on top of the Monadic Constraint Programming framework for Haskell. FD-MCP leverages Haskell’s rich static type system and powerful abstraction mechanisms for implementing syntactic sugar, model transformations and compilation to solver backends. Two backends are provided: a basic Haskell solver and a Gecode code generator. Our bench...

Gastric dysrhythmias, such as tachy- or bradygastria, have been reported in patients with functional dyspepsia (FD), but their role in symptom production is uncertain. It is also not known whether gastric dysrhythmias in these patients can be elicited by physiological gastric distension with a meal. We investigated the relationships between symptoms after ingestion of different volumes of water...
