Bear Hug: Russia's Return to the Middle East

Abstract: Russia’s return to the Middle East through its intervention in Syria after the Arab Spring has made it a critical player in regional politics. This chapter examines Russia’s return to the Middle within the context of Russia’s foreign policy goals under Putin. Russia’s activist foreign policy has been facilitated by some other factors as well. Long-term conflicts like Afghanistan, Iraq, Syria, and Libya have given Russia opportunities to introduce itself and establish “new facts on the ground”. For Russia, Syria is a test case for its desire for a “post-West” world, a multipolar world where Russia is a global player. Though Israel and Russia disagree on several issues like Iran, Hamas and Hezbollah, both believe that Islamist terrorism is their chief enemy. Russia-Turkey relations defy an easy definition and description; sometimes they work as friends, and sometimes like enemies, particularly in the post-Arab Spring period. Russia’s relations with the Saudis are “testy”.

Friendship-Like Graphs and It’s Classiffication

Abstract: A distance-compatible set-labeling (dcsl) of a connected graph G is an injective set assignment \(f : V(G) \rightarrow 2^{X},\) X being a nonempty set, such that the corresponding induced function \(f^{\oplus } :V(G)\times V(G) \rightarrow 2^{X}\) given by \(f^{\oplus }(uv)= f(u)\oplus f(v)\) satisfies \(\mid f^{\oplus }(uv) \mid = k_{(u,v)}^{f}d_{G}(u,v) \) for every pair of distinct vertices \(u, v \in V(G),\) where \(d_{G}(u,v)\) denotes the usual path distance between u and v and \(k_{(u,v)}^{f}\) is a constant. A dcsl f of G is k-uniform if all the constant of proportionality with respect to f are equal to k, and if G admits such a dcsl then G is called a k-uniform dcsl graph. And it has been already proved that, for a finite graph G, k-uniform dcsl graph G with is a finite set X if and only if k-embedding of G into a hypercube \({\mathbf {H}}(X)\). In this paper, we introduce Friendship-like graphs and its classification and prove that it admits 2-uniform dcsl.

Advances in Plasmonic Biosensors and Their Futuristic Applications

Abstract: The focus of this chapter is on different types of sensors based on plasmonic nanoparticles for detecting various analytes. These include biological and chemical entities including metal ions, organic molecules, proteins, biomarkers, nucleic acids (DNA and RNA) etc. Early detection of diseases is possible by detecting the presence or variations of several biological components in the human body. These are achievable through the development of specific biosensors. Here, we briefly discuss about the structure, sensing mechanisms, detection methods and applications of plasmonic biosensors.

Trends and correlates of hardcore smoking in India: findings from the Global Adult Tobacco Surveys 1 & 2

Abstract: Background: Data on the prevalence of hardcore smoking (HCS) among different socioeconomic status (SES) groups in low- and middle-income countries are limited. We looked at the prevalence and pattern of HCS in India with the following objectives: 1) to analyse the association between SES and HCS, 2) to find trends in HCS in different SES groups and 3) to find state-wide variations in hardcore smoking. Methods: Data of individuals aged ≥25 years from the Global Adult Tobacco Survey (GATS) India 2009-10 (N= 9223) and 2016-17 (N= 7647) were used for this study. If an individual met all the following criteria: (1) current smoker, (2) smokes 10 or more cigarettes/day, (3) smokes first puff within 30 minutes after waking up, (4) no quit attempt in the last 12 months, and (5) no intention to quit at all or in the next 12 months, s/he was identified as a hardcore smoker. Multiple regression analysis was done to find the factors associated with HCS. Results: Prevalence of HCS decreased from 3% in GATS 1 to 2.1% in GATS 2: males from 5.6% to 3.9% and females from 0.3% to 0.2%. Compared to the richest group the poorest, poor and those who belonged to the middle-income group were more likely to report HCS in GATS 1 and 2. However, only in the poorest SES group, there was an increase in the proportion of hardcore smokers in GATS 2 compared to GATS 1. Other factors that were significantly associated with HCS in both surveys were male gender, working adults, those with lower education, and households without any rules for smoking inside the home. Conclusions: Tobacco control and cessation efforts need to focus on individuals of poor SES groups, particularly in the high prevalence Indian states.

Spectral domain modeling of the effect of film purity for superconducting slotline

Abstract: A computation technique is presented to analyse the electromagnetic response of High Temperature Superconducting (HTS) film purity using a slotline. The complex conductivity of HTS films for three different material purity is modeled using Coffey-Clem (CC) unified theory. By using the surface impedance calculated by CC model, the dyadic Green's functions in Spectral Domain Method (SDM) are formulated for the slotline. The Galerkin's procedure is employed for the computation of the propagation parameters when HTS slotlines of different purities are guiding a fixed frequency microwave signal. Changes in the propagation parameters are analyzed for the variation of the film thickness at different working temperatures. The paper presents a modeling method for studying the microwave response of the HTS film purity.
