    Describing dynamical fluctuations and genuine correlations by Weibull regularity

    Full text link
    The Weibull parametrization of the multiplicity distribution is used to describe the multidimensional local fluctuations and genuine multiparticle correlations measured by OPAL in the large statistics e+e−→Z0→hadronse^{+}e^{-} \to Z^{0} \to hadrons sample. The data are found to be well reproduced by the Weibull model up to higher orders. The Weibull predictions are compared to the predictions by the two other models, namely by the negative binomial and modified negative binomial distributions which mostly failed to fit the data. The Weibull regularity, which is found to reproduce the multiplicity distributions along with the genuine correlations, looks to be the optimal model to describe the multiparticle production process.Comment: 10 pages, 2 figure

    The name of someone, something, institution had a certain meaning. A meaning depended so much on someone\u27sperception to an object. Perception of society to Sharia Bank had an impact to society behavior toward ShariaBank. There was a gap here between bank and society which had to be acted as a bridge through policy andsocialization program. Socialization policy which was planned, adaptive, and interesting could minimize themisperception risk. Socially, sosialization program was the enculturization of sharia bank values process, andit was understood as the form of civil education

    Capture of a diffusing lamb by a diffusing lion when both return home

    A diffusing lion pursues a diffusing lamb when both of them are allowed to get back to their homes intermittently. Identifying the system with a pair of vicious random walkers, we study their dynamics under Poissonian and sharp resetting. In absence of any resets, the location of intersection of the two walkers follows a Cauchy distribution. In presence of resetting, the distribution of the location of annihilation is composed of two parts: one in which the trajectories cross without being reset (center) and the other where trajectories are reset at least once before they cross each other (tails). We find that the tail part decays exponentially for both the resetting protocols. The central part of the distribution, on the other hand, depends on the nature of the restart protocol, with Cauchy for Poisson resetting and Gaussian for sharp resetting. We find good agreement of the analytical results with numerical calculations.Comment: 9 pages, 3 figure

    Nanocrystalline BaFe12O19 powders were prepared by microwave-hydrothermal method at 200 °C/45 min. The as-synthesized powders were characterized by using X-ray diffraction (XRD), thermogravimetry (TG) and differential thermal analysis (DTA). The present powders were densified at different temperatures, i.e., 750, 850, 900 and 950 °C for 1 h using microwave sintering method. The phase formation and morphology studies were carried out using XRD and field emission scanning electron microscopy (FE-SEM). The average grain sizes of the sintered samples were found to be in the range of 185–490 nm. The magnetic properties such as saturation magnetization and coercive field of sintered samples were calculated based on magnetization curves. A possible relation between the magnetic hysteresis curves and the microstructure of the sintered samples was investigated

    The structural analysis and magnetic investigation Mn1−xZnxFe2O4 with stoichiometry (x=0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0) were synthesized by solution combustion method using mixture of fuel this is first of its kind. As synthesized Mn–Zn nanoferrites were characterized by X-ray Diffractometer (XRD), Transmission electron microscopy (TEM) at room temperature. The magnetic domain relaxation was investigated by inductance spectroscopy (IS) and the observed magnetic domain relaxation frequency (fr) was increased with the increase in grain size. The Room temperature magnetic properties were studied using vibrating sample magnetometer (VSM). It was observed that the real and imaginary part of permeability (µ' and µ?), saturation magnetization (Ms), remanance magnetization (Mr) and magneton number (Mr/Ms) were decreases gradually with increasing Zn2+ concentration. The decrease in the saturation magnetization may be explained as, the Zn2+ concentration increases the relative number of ferric ions on the A sites diminishes and this reduces the A–B interaction. Hence synthesized materials are good for high frequency applications

    AIM : To determine the association between Salivary Fructosamine and Plasma Glycated Hemoglobin, Plasma Fasting and Post Prandial Glucose levels among Type II Diabetes mellitus patients and Non Diabetic healthy controls. OBJECTIVES : 1. To obtain saliva and blood samples from Type II Diabetes mellitus patients and Non Diabetic healthy controls. 2. To estimate the level of Salivary Fructosamine in saliva samples. 3. To estimate the levels of Plasma Glycated Hemoglobin, Plasma Fasting and Post Prandial Glucose levels in blood samples. 4. To determine the association between Salivary Fructosamine, Plasma Glycated Hemoglobin and Plasma Fasting and Post Prandial Glucose levels. METHODOLOGY : This cross sectional study was conducted over a period of five months. The study participants were divided into two groups, Type II Diabetes mellitus patients were included in Group 1, and non diabetic healthy individuals were included in Group 2. A total of 100 participants were included in the study with 50 participants in each group. Blood and saliva samples were collected from the participants to estimate the levels of Plasma Fasting Glucose, Plasma Post Prandial Glucose, Plasma Glycated Hemoglobin and Salivary Fructosamine. The data was compiled and analyzed using SPSS software and results were generated. RESULTS : The study results showed that Type II Diabetes mellitus patients had significantly higher levels of Salivary Fructosamine, when compared to non diabetic healthy individuals (p value < 0.001). Among the Group1 individuals high correlation was observed between Salivary Fructosamine, Plasma Fasting Glucose levels (r value of 0.934), Plasma Postprandial Glucose levels (r value of 0.910) and, Plasma Glycated Hemoglobin (r value of 0.893). In Group 2 individuals high correlation was observed between Salivary Fructosamine and Plasma Fasting Glucose levels (r value of 0.794), moderate correlation was observed between Salivary Fructosamine and Plasma Postprandial Glucose (r value of 0.530) and Plasma Glycated Hemoglobin levels (r value of 0.307). CONCLUSION : The overall study results showed that Salivary Fructosamine levels were significantly higher in diabetic patients when compared to healthy individuals. Also positive correlation was observed between Salivary Fructosamine, Plasma Fasting, Plasma Postprandial and Plasma Glycated Hemoglobin among Type II Diabetes mellitus patients. The study throws light on the potential use of Salivary Fructosamine for the diagnosis and post treatment monitoring of glycemic control among diabetic patients
