Hadronic Resonance Production with ALICE Experiment at LHC
Subhash Singha
Physics , 2013,
Abstract: The production of resonances in heavy-ion collisions is expected to be sensitive to the properties of strongly interacting matter created in such collisions. We report on the measurements of $\phi$ and $K^{*0}$ resonances in Pb-Pb collisions at $\sqrt{s_{NN}} $ = 2.76 TeV. The masses, widths and yields in Pb-Pb collisions as a function of centrality are compared to that in pp collisions to understand the role of re-scattering and regeneration. The resonance to non-resonance particle ratios are shown as a function of collision centrality and compared with the results at lower energies.

Abstract: The ALICE experiment at the LHC has measured the production of strange hadrons and resonances in Pb-Pb and pp collisions at unprecedented high beam energies. The study of strange hadrons and resonances helps us to understand the properties of the medium created in the heavy-ion collisions and its evolution. We present the yields ($dN/dy$) at mid-rapidity for strange hadrons ($\Lambda$, $\Xi^{-}$, $\Omega^{-}$, their anti-particles and $K_{S}^{0}$) and resonances ($\phi$ and $K^{*0}$) for several collision centrality intervals. The results from Pb-Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV are presented and compared to corresponding results from pp collisions and lower energy measurements. Baryon to meson ratios and resonance to non-resonance particle ratios relative to pp collisions are shown as a function of collision centrality and compared with the results at lower energies.

Computational Molecular Bioscience (CMB) , 2014, DOI: 10.4236/cmb.2014.43005
Abstract: Phylogenetic analysis may be considered to be a highly reliable and important bioinformatics tool. The importance of phylogenetic analysis lies in its simple manifestation and easy handling of data. The simple tree representation of the evolution makes the phylogenetic analysis easier to comprehend and represent as well. The varied applications of phylogenetics in different fields of biology make this analysis an absolute necessity. The different aspects of phylogenetic analysis have been described in a comprehensive manner. This review may be useful to those who would like to have a firsthand knowledge of phylogenetics.
An Assessment of the Literature and Recent Developments on the Shallow Wake in an Open Channel Flow
Arindam Singha,Ramaswami Balachandar
Advances in Civil Engineering , 2010, DOI: 10.1155/2010/969407
Abstract: Although shallow flows are very abundant both in nature and in flows of technological importance, their effective characterization started only recently. This type of flow, being vertically confined, exhibits some unique features, which are absent in conventional unconfined flows. A brief review of the related research articles indicates that the exploration of the shallow wake had occurred in three distinct chronological phases. Initially, almost all investigations were aimed at exploring the differences between shallow flows and unconfined flows. Given the differences, the second phase of investigations was mostly concerned with identifying the sources of these differences found already. The third and most recent group of investigations attempted to correlate the flow topology with the extent of the confinement and focused on more applied areas like control of wake instability and consequent effects on drag reduction, and the effect of the coherent structures on species transport. The present paper is intended to present retrospect of the seminal investigations regarding shallow flows, and summarizes the key results from widely ranging studies. Another motivation of the present paper is to provide a basis for future research of shallow wake. 1. Introduction Numerous flows occurring in nature can be regarded as shallow [1]. In these flows, the length scale in the horizontal direction is much greater than that in the vertical direction [2]. Examples of shallow flow can be found in rivers, headlands, estuaries, stratified lakes, and coastal seas [1]. Heat dissipated from the earth can bring forth density variation in the vertical direction which can induce shallow flow over mountains and hills [3]. Knowledge of the characteristics of shallow flow and its transport capacity is crucial in modelling and predicting the flow, besides assisting in analyzing the dispersion of heat, pollutants, and biological species. Furthermore, it would also aid in weather modelling as the waterbeds and marshlands play a crucial role in controlling the local weather condition [2]. From the perspective of fluid dynamics, shallow flows display important features due to the presence of the bounding surfaces in the form of the bed and the free surface. The bed imparts vertical shear; while the free surface acts as a stress-free weak boundary. A typical shallow wake can be generated by introducing a disturbance in the form of a bluff body in an otherwise plane flow. The resulting separation of flow from the sides of the body though similar to a deep wake would be modified due to
On Maximal Subsemigroups of Partial Baer-Levi Semigroups
Boorapa Singha,Jintana Sanwong
International Journal of Mathematics and Mathematical Sciences , 2011, DOI: 10.1155/2011/489674
Abstract: Suppose that is an infinite set with ||≥≥?0 and () is the symmetric inverse semigroup defined on . In 1984, Levi and Wood determined a class of maximal subsemigroups (using certain subsets of ) of the Baer-Levi semigroup ()={∈()∶ dom = and |?|=}. Later, in 1995, Hotzel showed that there are many other classes of maximal subsemigroups of (), but these are far more complicated to describe. It is known that () is a subsemigroup of the partial Baer-Levi semigroup ()={∈()∶|?|=}. In this paper, we characterize all maximal subsemigroups of () when ||>, and we extend to obtain maximal subsemigroups of () when ||=.
A Proximity based Retransmission Scheme for Power Line Ad-hoc LAN
Chitta Ranjan Singha
International Journal of Distributed and Parallel Systems , 2010,
Abstract: Power line as an alternative for data transmission is being explored, and also being used to a certainextent. But from the data transfer point of view, power line, as a channel is highly dynamic and hence not quite suitable. To covert the office or home wiring system to a Local Area Network (LAN), adaptive changes are to be made to the existing protocols. In this paper, a slotted transmission scheme is suggested, in which usable timeslots are found out by physically sensing the media. Common usable timeslots for the sender-receiver pair are used for communication. But these will not ensure safe packet delivery since packets may be corrupted on the way during propagation from sender to receiver. Therefore, we also suggest a proximity based retransmission scheme where each machine in the LAN, buffers good packet and machines close to the receiver retransmit on receiving a NACK.
A NEW HARDWARE CIRCUIT FOR EVALUATION OF VALUE OF A PRIME NUMBER WITH EXPONENTIAL FORM
SATRUGHNA SINGHA,SOURAV SAMANTA
International Journal of Engineering Science and Technology , 2011,
Abstract: In this paper a new hardware circuit has been proposed for evaluating value of a term in the form of xi easily,where x is the prime base and i is the exponent. Using greedy algorithm a large integer number can be represented by the multiplication of various prime numbers and each of the prime number may be in the form of xi . Without taking the general approach of multiplication for finding out the result of xi , the new and simple approach has been adopted. Certain pattern has been shown by detail study of the binary form of the prime basesand its exponent. Instead of multiply the prime base x with i times with itself, it can be possible to calculate the xi by performing simple logical shifts, addition or subtraction operations. Those operations are similar in nature. To calculate the exponent part, set of some similar operations have been performed repeatedly. The proposed circuit has been implemented by decoder, shift register, adder-subtractor, lookup table, counter and tri-state buffer. Exponent part of each of the prime base x has been computed by this common circuit by selecting appropriate similar type of operations by the help of the lookup table. Due to the fixed size of shift register and adder-subtractor, finite range of operations of the exponent of the corresponding prime base x has been computed with this proposed hardware circuit.

A STUDY OF ROLE OF NUTRITIONAL STATUS ON THE OUTCOME OF VIPERBITE – INDUCED ACUTE RENAL FAILURE AT A TERTIARY CARE TEACHING HOSPITAL.
Debasis Bandyopadhyay,Prasanta Singha
Reviews of Progress , 2013,
Abstract: Background: In India Vipera russelli (Russell's viper), is responsible for a large number of snakebite cases [1] reaching 95% of envenomations in the State of Jammu. V. russelli also are frequently encountered in India and throughout south-east Asia. In Maharashtra State, in India, the annual incidence of severe envenomation is about 70 per 100000 inhabitants and the mortality rate is about 2.4 per 100000 per year [2]. It has been reported that there are 5 million snake bites, resulting in 2.5 million envenoming, 125,000 deaths and perhaps three times that number of permanent sequelae in the world each year. The incidence of snake bite mortality is particularly high in Africa, Asia, Latin America and New Guinea. In India alone there may be as many as 50,000 snake bite deaths each year [3].It is well established that Viperid snake venoms induce renal failure [4,5,6,7] and especially most of the patients comes from the rural area. So in this perspective this study was important, as previously no such recorded data.Objective: The objective of the study was to assess the general nutritional status on admission, to provide additional support, to see the outcome in terms of morbidity and mortality and also to correlate the nutritional status with mortality& morbidity in Viper bite induced renal failure.Materials& Methods: In our study 23 established cases of Viper bite induced renal failure patients are recruited from the indoor admitted cases in our tertiary care teaching hospital from March 2010 to February 2011 They are provide with additional support. Nutritional status was correlated with morbidity and the serum albumin level.Results: Mortality in the study group was13.04%. in comparison with the 14.81% of the control group. Morbidity as hospital stays was 13.79 ± 3.19 days, in comparison with the19.12 ± 1.09 days of the control group. Correlation coefficient was- 0.28359 and – 0.25791 in the two groups.Conclusion: The present study indicates that additional nutritional support should be considered in all the hospital admitted patients, as
