Background of study aims and objective:Epicardial fat thickness is a novel parameter for predicting outcome and assessment of severity of coronary artery disease. Our present study aims to establish an association between epicardial fat thickness and coronary artery disease. Materials & Methods: patients of suspected CAD underwent coronary angiography. 100 subjects proven as confirmed cases were included in the study. Routine clinical examination, risk factor profile and anthropometric variables were also done. Severity of CAD was assessed using Gensini Score. Epicardial fat thickness was measured using 2D ECHO. For comparative analysis, 50 healthy individuals were also included in the study. Results: Epicardial fat thickness was significantly higher in cases (7.53 ± 1.79 mm) than controls (4.24 ± 1.09 mm). Female sex, hypertension, dyslipidemia, obesity were observed to affect EFT significantly. no difference in mean EFT was observed with age, diabetes, smoking, ECG changes and arterial territory involvement. BMI and Gensini scores both showed strong positive correlation with epicardial fat thickness. Conclusion: Epicardial fat thickness is associated and linearly correlates with onset and severity of CAD.

Dynamic Bayesian networks (DBns) can effectively perform modeling and qualitative reasoning for many dynamic systems. However, most of its inference algorithms involve complicated graphical transformations that are hard to program and time-consuming to compute. This article proposes a new recursive inference algorithm, which is a purely numerical method derived from probability theory and the characteristics of Bayesian networks to do both on-line and off-line inferences in discrete DBns. The most prominent advantages of this novel approach include: (1) it is an exact inference algorithm, thus its accuracy and stability can be guaranteed, (2) it avoids the complex graphical transformation so as to remarkably improve the inference speed, and (3) its concise recursive formulae facilitate programming of both forwards and backwards pass. All of these issues are verified by accurate mathematical derivation as well as a couple of application examples with comparison between the new algorithm and the two most prevailing inference approaches of discrete DBns - the interface algorithm and the forwards-backwards algorithm.

Investigation of a beach and its wave condi-tions is highly requisite for understanding the physicalprocesses in a coast. This study composes spatial andtemporal correlation between beach and nearshore pro-cesses along the extensive sandy beach of nagapattinamcoast, southeast peninsular India. The data collectionincludes beach profile, wave data, and intertidal sedimentsamples for 2 years from January 2011 to January *** field data revealed significant variability in beach andwave morphology during the northeast （nE） and southwest（SW） monsoon. However, the beach has been stabilized bythe reworking of sediment distribution during the calmperiod. The changes in grain sorting and longshoresediment transport serve as a clear evidence of thesediment migration that persevered between foreshoreand nearshore regions. The Empirical Orthogonal Function（EOF） analysis and Canonical Correlation Analysis （CCA）were utilized to investigate the spatial and temporallinkages between beach and nearshore criterions. Theoutcome of the multivariate analysis unveiled that theseasonal variations in the wave climate tends to influencethe bar - berm sediment transition that is discerned in thecoast.

In this paper, we propose and analyze a mathematical model to study the dynamics of a fishery resource system with stage structure in an aquatic environment that consists of two zones namely unreserved zone (fishing permitted) and reserved zone (fishing is strictly prohibited). In this model we introduce a stage structure in which predators are split into two kinds as immature predators and mature predators. It is assumed that immature predators cannot catch the prey and their foods are given by their parents (mature predators). It is also assumed that the fishing of immature predators prohibited in the unreserved zone and predator species are not allowed to enter inside the reserved zone. The local and global stability analysis has been specified. Biological and Bionomical equilibriums of the system are derived. Mathematical formulation of the optimal harvesting policy is given and its solution is derived in the equilibrium case by using pontryagin’s maximum principle.

pedestrians have unique needs to ensure their safety as they interact with others within a transportation system. Since this is especially true in third world context, it is imperative to gain a better understanding of pedestrian behaviors in developing countries. The goal is to have planners and engineers create appropriate design guidelines and inform policy decisions. Data on pedestrian characteristics and behavior metrics were gathered from midblock crossings in Bangalore, Karnataka, India. Quadratic and logistic regressions suggest that pedestrian delay and utilization of crossings increase with age, while conflicts decrease with it. Male waiting time is approximately half of female waiting time, and males are twice as likely to cause conflicts with motor vehicles. These strong patterns will hopefully aid in the understanding of pedestrian behavior in relation to motor vehicle traffic in urban areas of developing countries, encouraging safer crossings to be designed.
