Three Flavoured neutrino oscillations and the Leggett Garg Inequality

Three flavoured neutrino oscillations are investigated in the light of the Leggett-Garg inequality. The outline of an experimental proposal is suggested whereby the findings of this investigation may be verified. The results obtained are: (a) The maximum violation of the Leggett Garg Inequality (LGI) is $2.17036$ for neutrino path length $L_{1}=140.15$ Km and $\Delta L=1255.7$ Km.(b) Presence of the mixing angle $\theta_{13}$ enhances the maximum violation of LGI by $4.6\%$.(c) The currently known mass hierarchy parameter $\alpha = 0.0305$ increases the the maximum violation of LGI by $3.7\%$. (d)Presence of CP violating phase parameter enhances the maximum violation of LGI by $0.24\%$, thus providing an \textit{alternative indicator of CP violation} in 3-flavoured neutrino oscillations.Comment: 8 pages, 5 figures, late

Reorganizing Educational Institutional Domain using Faceted Ontological Principles

The purpose of this work is to find out how different library classification systems and linguistic ontologies arrange a particular domain of interest and what are the limitations for information retrieval. We use knowledge representation techniques and languages for construction of a domain specific ontology. This ontology would help not only in problem solving, but it would demonstrate the ease with which complex queries can be handled using principles of domain ontology, thereby facilitating better information retrieval.Comment: 26 pages, 12 figures, KNOWLEDGE ORGANIZATION Journal Pape

PathAB: A New Method to Estimate End-to-End Available Bandwidth of Network Path

Estimating available bandwidth accurately is extremely important for many network related applications, especially the ones which need real-time traffic information. With the ever increasing use of Internet, several available bandwidth measurement techniques have been proposed. But most of them assume fluid traffic model, whereas studies show that current Internet traffic follows Poisson distribution. Moreover, very few can operate in stand-alone mode and have relatively high estimation errors. We propose a new method, PathAB, which combines the concepts of three existing algorithms, MoSeab, PoissonProb and PathChirp. It first obtains a rough estimation of available bandwidth using an exponential probing train, and later obtains the final estimate using several Poisson distributed probing trains. It can operate both in client-server and stand-alone modes. Unlike other stand-alone methods, PathAB sends very small echo packets back-to-back after the large probe packets to reduce the cross-traffic effect in returning path as well as the estimation error

An Overview of Management of Cancer Approach with Medical and Dental Considerations

This review emphasizes about making the members of the professional Colleges aware of some important aspects of oral cancer in particular & cancer of body in general and its impact on the Dental Surgeons to be a part of the weapon against fighting this devastating disease. Cancer is the major public health problem affecting developed and developing countries. Therefore this review focusses on cancer management by taking into mind dental and medical considerations

Coronavirus Disease 2019 (COVID-19): Future Challenges and Recommendations for Dental Settings

The novel coronavirus outbreak is a contagious disease affecting the countries around the world. The quick advancing nature of pandemic has gripped the entire community making it a public health emergency. Infection control preventive measures are necessary to prevent it from further spreading. Medical practitioners, health care workers and Dentists are at high risk of acquiring and transmission of infection. The virus transmission occurs through respiratory tract, aerosols and droplets. Clinical manifestations of virus vary from mild to severe sickness. This review article mainly emphasizes on all the information collected to date on the virus, and future recommendations for dental settings to manage the further spread of this virus

A Society Based Research to Assess Adherence of Antiretroviral Therapy

Access Adherence to Antiretroviral Therapy. A community-based antiretroviral (ART) drugs adherence study was conducted in Kolkata, India beginning in January and concluding in March 2011. This study was designed to explore the level of adherence as well as factors influencing adherence to ART by those who are receiving treatment through a public health care delivery system. This health care system is implemented through the National AIDS Control Program in the state of West Bengal, India. The research findings showed a high degree of non-adherence, between 48-52%, among the ART recipients. The analysis highlights a number of key factors negatively influencing adherence including long waiting time at the ART center, distance from residence to ART Centre, travel related expenditure, and fear of being identified as HIV + to family members and neighbors. Some positive influences were identified in the data as well. If a person is a member of a positive people network there is a greater chance for adherence as well as if an individual self-identifies as positive to others. However, no single factor, rather a combination of several factors, proved to be responsible for influencing ART adherence among recipients. &nbsp

Strings from Orientifolds

We construct models in 1+1 dimensions with chiral (0,N) supersymmetry by taking orientifolds of type IIB on an eight-torus identified by different numbers of reflections. The resulting models have Dirichlet strings, fivebranes and ninebranes stretched along different directions. The cases we study in detail have residual chiral supersymmetry (0,8), (0,4) and (0,2). The gravitational anomaly in all cases is shown to cancel.Comment: 30 pages, Latex, v2: references added, version to appear in Nucl. Phys.
