Study of dynamical charge fluctuations in the hadronic medium

The dynamical charge fluctuations have been studied in ultra-relativistic heavy-ion collisions by using hadronic model simulations, such as UrQMD and HIJING. The evolution of fluctuations has been calculated at different time steps during the collision as well as different observation window in pseudorapidity (\DelEta). The final state effects on the fluctuations have been investigated by varying $\bigtriangleup\eta$~ and the time steps with the aim of obtaining an optimum observation window for capturing maximum fluctuations. It is found that $\bigtriangleup\eta$~ between 2.0 and 3.5 gives the best coverage for the fluctuations studies. The results of these model calculations for Au+Au collisions at $\sqrt{s_{\rm NN}}$~=~7.7 to 200~GeV and for Pb+Pb collisions at 2.76 TeV are presented and compared with available experimental data from the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC).Comment: 6 pages, 4 Figure

Ensemble Boosted Tree based Mammogram image classification using Texture features and extracted smart features of Deep Neural Network

/n This work proposes a technique of breast cancer detection from mammogram images. It is a multistage process which classifies the mammogram images into benign or malignant category. During preprocessing, images of Mammographic Image Analysis Society (MIAS) database are passed through a couple of filters for noise removal, thresholding and cropping techniques to extract the region of interest, followed by augmentation process on database to enhance its size. Features from Deep Convolution Neural Network (DCNN) are merged with texture features to form final feature vector. Using transfer learning, deep features are extracted from a modified DCNN, whose training is performed on 69% of randomly selected images of database from both categories. Features of Grey Level Co-Occurrence Matrix (GLCM) and Local Binary Pattern (LBP) are merged to form texture features. Mean and variance of four parameters (contrast, correlation, homogeneity and entropy) of GLCM are computed in four angular directions, at ten distances. Ensemble Boosted Tree classifier using five-fold cross-validation mode, achieved an accuracy, sensitivity, specificity of 98.8%, 100% and 92.55% respectively on this feature vector

Market integration in wholesale rice markets in India

This paper tests for market integration in 55 wholesale rice markets in India using monthly data over the period January 1970 – December 1999. The technique of Gonzalez-Rivera and Helfand (2001) is used to identify common factors across various markets. It is discovered that market integration is far from complete in India and a major reason for this is the excessive interference in rice markets by government agencies. As a result it is hard for scarcity conditions in isolated markets to be picked up by markets with abundance in supply. A number of policy implications are also considered

Stability Analysis of Integrated Pest Management with Impulsive Biological Control

The aim of the present work is to study the dynamics of stage-structured pest control model including biological control, i.e. by releasing of natural enemies and infected pests periodically. It is assumed that only immature susceptible pests are attacked by natural enemies admitting Beddington DeAngelis functional response and mature susceptible pests are contacted by infected pests with bilinear incidence rate and become exposed. The sufficient condition for local stability of pest extinction periodic solution is derived by making use of Floquet’s theory and small amplitude perturbation technique. The global attractivity of pest extinction periodic solution is also established by applying comparison principle of impulsive differential equations

Clinical Evaluation of Xylazine-Butorphanol-Guaifenesin-Ketamine as Short-Term TIVA in Equines

Xylazine (1.1 mg/kg), butorphanol (0.02 mg/kg), guaifenesin 5% (20 mg/kg), and ketamine (2.2 mg/kg) combinations were able to induce short-term surgical anaesthesia for 23.33 ± 2.57 min in Spiti ponies with excellent to good muscle relaxation and analgesia. Urination and neighing was a constant feature during recovery period. Biphasic P wave, biphasic T wave, and depressed PR segment were common electrocardiographic findings. Biochemical attributes were within physiological limits except a significant increase in ALT values during anaesthesia. The values returned to normal during recovery ruling out any renal or hepatic toxicity. Occasionally, negative T wave, notched P wave, and sinus block were noticed. It is recommended that the anaesthetic combinations xylazine-butorphanol-guaifenesin-ketamine can be safely used for short-term total intravenous anaesthesia (TIVA) in equines under field conditions

Presentation and management of bilateral fracture shaft humerus in a multiple myeloma patient: An extremely rare case report and review of literature

Multiple myeloma (MM) is a malignancy of plasma cells and the second most common hematologic malignancy (13%); these cellsaccumulate in bone marrow and overproduce a monoclonal protein. The bone disease develops in 80–90% of patients with MMincludes bone pain, pathologic fractures (40%), spinal cord compression (5%), and hypercalcemia. Pathological fractures can occurin extremities, but bilateral involvement is extremely rare. We report a case of 65-year-old male presented with a chief complaint ofspontaneous bilateral humerus shaft fractures. On subsequent workup, MM was confirmed. The patient was managed with internalfixation bilaterally and showed favorable union at 1-year follow-up

Excellent impact strength of ethylene-methyl acrylate copolymer toughened polycarbonate

The intrinsic notch sensitivity of polycarbonate (PC) demands improvement in the notched impact strength for a variety of applications. Blends of PC/ethylene-methyl acrylate (EMA) copolymer of different compositions were prepared by melt blending using a co-rotating twin-screw extruder. The notched izod impact strength of PC/EMA blends showed a positive blending effect and increased 381% with incorporation of a very little amount of EMA (5%) with a marginal decrease in the tensile strength of PC. Tensile data was also analyzed by using predictive theories. Incorporation of EMA decreases the glass transition temperature of PC and facilitates its processing. Scanning electron micrographs of cryogenically fractured samples after etching were used to study the phase structure. A two phase morphology was seen with a fine dispersion of rubber granules in the PC matrix. On the other hand, the impact fractured surface of PC/EMA blends indicated debonding of EMA particles, leaving hemispherical bumps, indicating inadequate interfacial adhesion between PC and EMA
