Game Theoretic Approach for Cognitive Radio Networks

Cognitive radio is a promising approach to make efficient use of spectrum by rapidly adapting the changes in wireless environment. In such networks, nodes are expected to be aware of their environment and must be able to learn from the outcomes of past decisions. Game theory which comprise of analytical tools designed to study interactive decision-making processes can be applied effectively to solve some of such complex problems. This paper discusses the significance of using game theory for cognitive radio networks and resource allocation, and various game theoretic approaches used for it.

Chemical synthesis and study of structural and optoelectronic properties of CdS thin films: Effect of SILAR growth cycles

CdS thin films were deposited on glass substrates by using successive ionic layer adsorption and reaction (SILAR) method at room temperature. The effect of SILAR growth cycles on structural, morphological, optical and electrical properties of the films has been studied. The thickness of the deposited film is measured by employing weight difference method. The X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) studies showed that all the films exhibit polycrystalline nature and are covered well with glass substrates. The values of average crystallite size were found to be 53 nm, 58 nm, 63 nm and 71 nm corresponding to the thin films deposited with 30, 40, 50 and 60 SILAR growth cycles respectively. From the UV–VIS spectra of the deposited thin films, it was seen that both the absorption properties and energy bandgap of the films changes with increasing number of SILAR growth cycles. A decrease of electrical resistivity has been observed with increasing SILAR growth cycles. &nbsp

There are many earliest TTS systems are available but for Devanagari and Roman scripts are not available

Combined protein C and protein S deficiency with pregnancy

A 35 year old female patient, married since 8 years, G6P1L1SA4 was registered with our unit since 8th week of gestation. She was a known case of protein C and protein S deficiency diagnosed 7 years ago (thrombotic profile- protein C: 70% normal: 70-100%, protein S: 55% normal: 70/140%, AT-III: 116% normal 70/140%, factor V leiden: no mutation detected) which was detected on evaluation for her bad obstetric history. ACLA was also positive. She was started on injection low molecular weight heparin 0.6 mg s/c OD, in addition to continuing Tb. Aspirin 75 mg which had been started when the pregnancy was registered. Foleys induction was done at 39 weeks of gestation in view of previous LSCS with pre-eclampsia. Emergency LSCS was done in view of previous LSCS with non-progress of labour. Male child weighing 2.4 kg was born which is doing well. A patient having combined deficiency of both factors protein C and protein S is very rare. Anticoagulation therapy is the cornerstone in the management of patients with inherited coagulation defects

Acute and subchronic toxicity study of Tamra Bhasma (incinerated copper) prepared with and without Amritikarana

AbstractBackgroundTamra Bhasma (TB) is one among herbo-metallic preparations extensively used in routine ayurvedic practice. In the present era, Bhasma preparations used in ayurvedic system of medicines are always under stern observations for containing heavy metals which may raise the question of safety aspect.ObjectiveIn the present study, TB prepared with and without Amritikarana was subjected to toxicity study to ascertain the role of Amritikarana on safety profile of TB in rats.Materials and methodsBoth the samples of TB were administered to rats for 28 consecutive days at the doses of 5.5, 27.5, and 55 mg/kg. The effects of both drugs were assessed on ponderal changes, hematological, serum biochemical, and histopathology of various organs.ResultsResults showed that both the samples of TB did not produce any sign and symptoms of toxicity at therapeutic dose level (5.5 mg/kg) and therapeutic equivalent dose (TED) × 5 (27.5 mg/kg) while at higher dose of TED × 10 (55 mg/kg) TB has mild toxicity in liver, kidney, heart, and thymus on repeated administration for 28 days in rats. The sample without Amritikarana has more magnitude of toxicity than the sample with Amritikarana.ConclusionFrom the present study, it is concluded that TB with Amritikarana was found to be relatively safer than TB without Amritikarana at different dose levels in rats and hence suggest for safely use in humans at therapeutic dose level. It proves the role of Amritikarana in the preparation of TB

A prospective observational study of foetal outcome in twin pregnancy delivering at a tertiary health care center of South Gujarat

Background: Worldwide increased incidence of twin gestation. The rates of twin gestation have a direct effect on the rates of preterm birth and its co-morbidities. Importantly, this increased risk applies to each fetus and is not simply the result of more foetuses.Methods: This prospective study was carried out in department of obstetrics and gynaecology. 100 consecutive subjects fulfilling inclusion criteria   admitted to labour room and obstetrics intensive care enrolled over a period of around 1 year.Results: In this study twin delivery accounted for 1.3% of all delivery at our institute. On analysing neonatal morbidities Prematurity was commonest 65%, VLBW (23% first twin, 30% second twin), RDS (9% first twin, 13% second twin), birth asphyxia (7% first twin, 12% second twin), neonatal hyperbilirubinemia (7% first twin, 8% second twin). 34% of first twin and 40% of second twin required NICU admission. Early neonatal death observed in 6% of first twin and 8% of second twin. It was observed that proportion of neonatal complications was more in MCDA as compared to DCDA and in un-booked subjects as compared to booked subjects. This difference is statistically significant among both twin (p value<0.05).Conclusions: Twin pregnancy is associated with high perinatal morbidity. Specialized obstetrics and Intensive Neonatal care can decrease neonatal morbidity and mortality in twin gestation. We need to be extra vigilant in monochorionic twins and twin pregnancy with inadequate antenatal care

Relativistic calculations of the lifetimes and hyperfine structure constants in 67^{67}Zn+^{+}

This work presents accurate {\it ab initio} determination of the magnetic dipole (M1) and electric quadrupole (E2) hyperfine structure constants for the ground and a few low-lying excited states in $^{67}$Zn$^{+}$, which is one of the interesting systems in fundamental physics. The coupled-cluster (CC) theory within the relativistic framework has been used here in this calculations. Long standing demands for a relativistic and highly correlated calculations like CC can be able to resolve the disagreements among the lifetime estimations reported previously for a few low-lying states of Zn$^{+}$. The role of different electron correlation effects in the determination of these quantities are discussed and their contributions are presented.Comment: 9 pages, 1 figure. submitted to J. Phys.

Combining High Oleic Acid Trait and Resistance to Late Leaf Spot and Rust Diseases in Groundnut (Arachis hypogaea L.)

High oleic trait, resistance to rust and late leaf spot (LLS) are important breeding objectives in groundnut. Rust and LLS cause significant economic loss, and high oleic trait is an industry preferred trait that enhances economic returns. This study reports marker-assisted selection to introgress high oleic content, resistance to LLS and rust into Kadiri 6 (K 6), a popular cultivar. The alleles for target traits were selected using linked allele-specific, simple sequence repeats and single nucleotide polymorphic markers. The F1s (384), intercrossed F1s (441), BC1F1s (380), BC1F2s (195), and BC1F3s (343) were genotyped to obtain desired allelic combination. Sixteen plants were identified with homozygous high oleic, LLS and rust resistance alleles in BC1F2, which were advanced to BC1F3 and evaluated for disease resistance, yield governing and nutritional quality traits. Phenotyping with Near-Infrared Reflectance Spectroscopy identified three lines (BC1F3-76, BC1F3-278, and BC1F3-296) with >80% oleic acid. The identified lines exhibit high levels of resistance to LLS and rust diseases (score of 3.0–4.0) with preferred pod and kernel features. The selected lines are under yield testing trials in multi-locations for release and commercialization. The lines reported here demonstrated combining high oleic trait with resistance to LLS and rust diseases
