    Investigating the hybrid textures of neutrino mass matrix for near maximal atmospheric neutrino mixing

    In the present paper, we have studied that the implication of a large value of the effective Majorana neutrino mass in case of neutrino mass matrices having either two equal elements and one zero element (popularly known as hybrid texture) or two equal cofactors and one zero minor (popularly known as inverse hybrid texture) in the flavor basis. In each of these cases, four out of sixty phenomenologically possible patterns predict near maximal atmospheric neutrino mixing angle in the limit of large effective Majorana neutrino mass. This feature remains irrespective of the experimental data on solar and reactor mixing angles. In addition, we have also performed the comparative study of all the viable cases of hybrid and inverse hybrid textures at 3σ\sigma CL

    From evidence-based to decision-analytic medicine: A mammography case study

    The technology needed to implement mass screening by mammography existed well before the implementation of national screening programmes. This delay arose partly because of the complexities involved in conducting randomised controlled trials (RCTs) of screening programmes. These complexities not only extend the time needed to conduct trials of cancer screening, they reduce the external validity of the results. There is potential to improve the application of evidence-based medicine (EBM) to the evaluation of cancer screening programmes and other complex interventions through adding insights from Operational Research and Decision Theory. This would extend EBM to what might be called Decision-Analytic Medicine (DAM)

    Arrested States of Solids

    Solids produced as a result of a fast quench across a freezing or a structural transition get stuck in long-lived metastable configurations of distinct morphology, sensitively dependent on the processing history. {\it Martensites} are particularly well studied examples of nonequilibrium solid-solid transformations. Since there are some excellent reviews on the subject, we shall, in this brief article, mainly present a summary of our work on the nonequilibrium statistical mechanics of Martensites.Comment: 4 figs (3 embedded eps and 1 'slide.gif' separate), review written for Current Scienc
