Non-relativistic limit for Higher Spin Fields and Planar Schroedinger Equation in 3D

Higher spin (HS) fields naturally occur in string theory, they are considered as a candidate for dark matter and may also appear as a collective excitation in condensed matter systems. In some cases one may study the HS fields in the non-relativistic settings. Thus, it is of interest to know the non-relativistic limit of HS fields and how to find the Schroedinger equation as the dynamical equation in this limit. In this paper, we consider the non-relativistic limit of HS fields in Minkowskian spacetime in 3D. We work both at the level of equation of motion and action/Lagrangian density. We find the systematic procedures in both settings and show that they can be generalized to arbitrary HS fields

Application of Soft Computing Techniques for Prediction of Slope Failure in Opencast Mines

One of the most arduous jobs in the industry is mining which involves risk at each working stage. Stability is the main focus and of utmost importance. FOS when calculated by traditional deterministic approach cannot represent the exact state at which the slope exists, though it gives a rough idea of the conditions and overall safety factor. Various approaches like numerical modelling, soft computing techniques allow us with the ease to find out the stability conditions of an unstable slope and the probability of its failure in near-by time. In this project, the stability conditions of some of the benches of Bhubaneswari Opencast Project, located in Talcher, have been evaluated using the soft-computing techniques like Artificial Neural Network implemented using MATLAB and then the results are being compared with the Numerical Model results from the software FLAC which deploys Finite Difference Method. A particular slope (CMTL-179, Seam-3) has been studied and the respective factor of safety for each slope has been predicted using both the Artificial Neural Network and FLAC. Initially the data related to bench height, slope angle, lithology, cohesion, internal angle of friction, etc. are determined for the respective rock of the slope of which the FOS is to be calculated. . A total of 14 training functions were used to train the model. The best training was found in Scaled Conjugate Gradient Backpropagation which corresponds to a regression coefficient of 91.36% during training and 88.24% overall. The best Validation Performance was also found at 60 epochs with Mean Squared Error of 0.069776. According to the trained neural network, it was found that the slope was 44.5% stable with a FOS 1.0226. Using the software FLAC, it was found that the slope was stable with FOS=1.17. The generic model will thus allow us to get a range of probability for the slope to fail so that necessary arrangements can be made to prevent the slope failure

An observational study of the effect of escitalopram and etizolam in type 2 diabetes mellitus patients with depression

Background: Past decades have witnessed a rapid rise in the prevalence of diabetes mellitus; estimated to affect 415 million adults worldwide and 69.1 million adults in India. There has been an increased prevalence of diabetes associated depression, which can aggravate the symptoms of depression and diabetes associated complications. Use of tricyclic antidepressants (TCA) can disturb the glycemic control. Escitalopram is a selective serotonin reuptake inhibitor (SSRI) and Etizolam is a new safe antianxiety agent. The objective of this study was to study the prevalence of depression and anxiety in type 2 diabetes mellitus patients and to assess the efficacy of escitalopram and etizolam in the treatment of depression and/or anxiety in type 2 diabetes mellitus patients.Methods: Total 125 patients diagnosed with type 2 diabetes mellitus with fulfilling the inclusion and exclusion criteria were included in the study. Informed written consent was obtained from the patients willing to participate in the study. They were screened for the presence of depression with the help of PHQ-9. Their demographic features were recorded and initial laboratory investigations done. Haemogram, blood sugar level - fasting (BSL-F) and postprandial (PP), serum alanine transferase (ALT), serum creatinine and Urine routine analysis. Patients were started on Escitalopram (10 mg) + Etizolam (0.5 mg) daily for 30 days and others were not treated and acted as control; keeping the management of diabetes mellitus unchanged for all. Laboratory investigations were repeated after 30 days.Results: The prevalence of depression with/without anxiety was 35.2%. 51 patients treated with Escitalopram + Etizolam improved clinically and biochemically. There was a significant (P < 0.05) improvement in BSL-F and PP and HbA1C in patients treated with Escitalopram + Etizolam.Conclusions: Prevalence of depression among type 2 diabetes mellitus was found to be 35% in this study. Fifty one patients treated with escitalopram + etizolam improved clinically as well as biochemically. There was significant improvement in BSL-F, BSL-PP and HbA1c. Escitalopram may be considered as antidepressant of choice in such cases

Science with the Daksha High Energy Transients Mission

We present the science case for the proposed Daksha high energy transients mission. Daksha will comprise of two satellites covering the entire sky from 1~keV to $>1$~MeV. The primary objectives of the mission are to discover and characterize electromagnetic counterparts to gravitational wave source; and to study Gamma Ray Bursts (GRBs). Daksha is a versatile all-sky monitor that can address a wide variety of science cases. With its broadband spectral response, high sensitivity, and continuous all-sky coverage, it will discover fainter and rarer sources than any other existing or proposed mission. Daksha can make key strides in GRB research with polarization studies, prompt soft spectroscopy, and fine time-resolved spectral studies. Daksha will provide continuous monitoring of X-ray pulsars. It will detect magnetar outbursts and high energy counterparts to Fast Radio Bursts. Using Earth occultation to measure source fluxes, the two satellites together will obtain daily flux measurements of bright hard X-ray sources including active galactic nuclei, X-ray binaries, and slow transients like Novae. Correlation studies between the two satellites can be used to probe primordial black holes through lensing. Daksha will have a set of detectors continuously pointing towards the Sun, providing excellent hard X-ray monitoring data. Closer to home, the high sensitivity and time resolution of Daksha can be leveraged for the characterization of Terrestrial Gamma-ray Flashes.Comment: 19 pages, 7 figures. Submitted to ApJ.

Engineering A Titanium And Polycaprolactone Construct For A Biocompatible Interface Between The Body And Artificial Limb

Intraosseous transcutaneous amputation prostheses may be able to overcome the problems that stem from the nonuniform distribution of pressure seen in the conventional stump-socket prosthetic replacement devices. Transcutaneous devices have had limited success in amputees. By optimizing the attachment of the skin to the prosthetic, intraosseous transcutaneous amputation prostheses may become clinically viable options. This report details studies evaluating the development of a modified titanium construct with a specially machined surface to increase the adherence of tissue as well as scaffold. A computer-aided biology tool was used to fabricate polycaprolactone (PCL) scaffolds with a specific three-dimensional architecture. To extrude the PCL, it was dissolved in acetic acid to produce a 70% PCL liquid. A scaffold with a porosity of \u3e50% was fabricated to have a tensile strength similar to skin. The presence of a specially machined surface greatly increased the adhesion of the PCL scaffold to the titanium constructs. When the 70% PCL was properly neutralized by heating at 55°C and washing in 90% ethanol (EtOH), there was only a decrease (10%) in the viability of cells seeded onto the PCL constructs when compared with the cells in culture. The antibacterial properties of titanium dioxide anatase, silver nanoparticles, and chlorhexidine diacetate mixed in either type I collagen or hyaluronic acid (HA) were assessed. The addition of 1% (w/w) chlorhexidine diacetate in HA resulted in a 71% decrease in bacteria seen in nontreated HA. These results show promise in developing a novel engineered titanium and PCL construct that promotes effective adhesion between the titanium-skin interface. Copyright 2010, Mary Ann Liebert, Inc

Not AvailableVillosiclava virens (Ustilaginoidea virens) an ascomycete fungal pathogen that causing false smut disease in rice and has become a serious production constraint in various rice-growing regions of India due to its detrimental effects on grain yield and quality. A roving survey was conducted during Rabi 2020 in Tamil Nadu, Uttar Pradesh and Karnataka state and the false smut disease severity was ranged between 9.2‒ 27.9 %. During survey heavy incidence was noticed in a variety BPT 5204. Totally 97 fungi were isolated and characterized from rice smut balls. Among them nine Uttar Pradesh, thirteen Tamil Nadu and two Karnataka isolates were identified as V. virens and remaining were as associated seed pathogens viz., Microdochium sp., Fusarium sp., Curvularia sp., Nigrospora sp., Aspergillus sp., Penicillium sp., Trichoderma sp., Epicocum sp. and Trichothecium sp. based on cultural and spore morphology. The identity of the pathogen was further confirmed through PCR analysis using ITS 1 and 4 primers and sequencing (NCBI) and the identified cultures were deposited at internationally recognised culture collection NAIMCC, Mau. Different isolates of V. virens showed variation in the cultural morphology, size, colour and shape of the conidia. A total of 16 Trichoderma, 10 Bacillus, 8 Pseudomonas strains were screened against V. virens among them, T. longibrachiatum, T. afroharzianum, T. harzianum, Bacillus subtillis, P. fluorescens and P. aeruginosa were showed highest percent inhibition. Further these strains were evaluated under pot condition along with combination of T. harzianum + B. subtillis + P. fluorescens (Biogrow) in three set of experiments through seed priming, soil application and foliar application. Rather than soil application seed priming and foliar application find more effective to control disease. The survivability of V. virens in the soil was also studied by applying giant cultures produced on rice seeds and grains. The complete experiments were conducted in ICAR-NBAIM, Mau with a time period of study.Not Availabl
