A soft decoding technique is discussed in this paper to improve the performance of long-distance optical networks (LDOTNs). LDOTNs are affected by phase noise and nonlinearities generated inside fiber. The investigations proposed LDOTN were carried out dual-polarization 16-quadrature amplitude modulation (DP-16QAM), DP-64QAM over single-mode fiber (SMF) digital signal processing (DSP) methodolo...

This article is a report summarizing recent progress in the geometry of negative Ricci and scalar curvature. It describes the range of general existence results of such metrics on manifolds of dimension ≥ 3. Moreover it explains flexibility and approximation theorems for these curvature conditions leading to unexpected effects. For instance, we find that “modulo homotopy” (in a specified sense)...

A D-shaped elliptical hollow core fiber surface plasmon resonance (SPR) sensor is proposed and analyzed here using gold titanium oxide (TiO 2 ) layer. The geometry consists of a doped with concentric central air hole. finite element method-based simulation software COMSOL Multiphysics used for numerical analysis. Both TiO layers are optimized. responds over wide range refractive index (RI) from...

The pharmacological interaction of antibiotic combinations tylosin and colistin was studied. For this purpose, an in vitro challenge method used. results were used to calculate their using the graphic representation known as ISOBOLOGRAM. pure salts tartrate sulfate obtained from manufacturer product, Laboratorios Ecozoo SA de CV Mexico. bioassay agar wells quantify results, following criteria u...

The aim of this work is to analyze the role of the “surprise” in marketing food (SMF), with particular attention to the cognitive and emotional processes that can be elicited by these toys. Usually, the advertising messages induce people to believe that an emotion of surprise is really related to the SMF. Our main questions are: could an object found in a food-product really elicit an emotion o...

Magnetic field therapy has recently become a widely used complementary/alternative medicine for the treatment of vascular, as well as other musculoskeletal pathologies, including soft tissue injuries. Recent studies in our laboratory and others have suggested that acute static magnetic field (SMF) exposure can have a modulatory influence on the microvasculature, acting to normalize vascular fun...

OBJECTIVES The aim of this study was to investigate the effects of static magnetic field (SMF) during transplantation of the ovarian tissue into the testis. MATERIALS AND METHODS In this experimental study, ovaries of 6- to 8-week-old female Naval Medical Research Institute (NMRI) mice were randomly divided into four groups: i. Fresh ovaries were immediately transplanted into the testicular t...

After seven-day exposure to 0.5-Tesla Static Magnetic Field (SMF), Adipose-derived Stem Cells (ASCs) and those labeled by superparamagnetic iron oxide (SPIO) nanoparticles were examined for viability by methyl thiazol tetrazolium (MTT) assay, proliferation by cell counting and bromodeoxyuridine (BrdU) incorporation, DNA integrity by single cell gel electrophoresis, surface antigen by flow cytom...

OF THESIS ECONOMIC ANALYSIS OF CELLULASE PRODUCTION BY CLOSTRIDIUM THERMOCELLUM IN SOLID STATE AND SUBMERGED FERMENTATION Dependence on foreign oil remains a serious issue for the U.S. economy. Additionally, automobile emissions related to petroleum-based, fossil fuel has been cited as one source of environmental problems, such as global warming and reduced air quality. Using agricultural and f...

Innovations in optical fiber technology are revolutionizing world communications. The focus of this paper is the development of optical fibers that within 20 years displaced copper wire as the transmission medium of choice for most commercial applications in telecommunications systems and computer networks worldwide. High speed and ultra-high capacity of optical communications have emerged as t...
