Common gauge origin of discrete symmetries in observable sector and hidden sector

An extra Abelian gauge symmetry is motivated in many new physics models in both supersymmetric and nonsupersymmetric cases. Such a new gauge symmetry may interact with both the observable sector and the hidden sector. We systematically investigate the most general residual discrete symmetries in both sectors from a common Abelian gauge symmetry. Those discrete symmetries can ensure the stability of the proton and the dark matter candidate. A hidden sector dark matter candidate (lightest U-parity particle or LUP) interacts with the standard model fields through the gauge boson Z', which may selectively couple to quarks or leptons only. We make a comment on the implications of the discrete symmetry and the leptonically coupling dark matter candidate, which has been highlighted recently due to the possibility of the simultaneous explanation of the DAMA and the PAMELA results. We also show how to construct the most general U(1) charges for a given discrete symmetry, and discuss the relation between the U(1) gauge symmetry and R-parity.Comment: Version to appear in JHE

This study aimed to describe the level of mastery of diction, illustrating the ability to write essays arguing and explaining relationships diction mastery of the ability to write essays siswa.Penelitian argument was held in SMA Negeri 1 Berastagi. Sample as many as 40 students, which is taken Random Sampling (Random) from 9 class X, and was elected class X-1 as an object of research.Before testing the hypothesis, first performed followed by descriptive data and test requirements analysis, test for normality and linearity test. To test the hypothesis used formula product moment correlation significance level of 5%. From the description of the data obtained diction skills class X SMA Negeri 1 Berastagi learning year 2012/2013, quite well with the average value of 75.625 and a standard deviation of 7.18 and an argument essay writing skills of students is also quite good with an average value of 71.625 and a standard deviation of 7.02. The correlation coefficient menunjukkanrhitung> rtabel or 0.663> 0.312 so it can be concluded that there is a significant relationship between mastery of diction on the ability to write an argument essay in class X SMA Negeri 1 Berastagi Learning Year 2012/2013. Linearity test results indicate that the relationship between Mastery Ability Test Diction for Writing Argumentation Writing ability is linear regression equation: Y = 22.624 + 0.648 X and Fhitung = 0.715> F table = 2.30. Thus the higher ability students mastery of diction, the higher the student's ability to write an argument essay. keyword, mastery of diction is associated with writing arguments

From dense-dilute duality to self duality in high energy evolution

I describe recent work on inclusion of Pomeron loops in the high energy evolution. In particular I show that the complete eikonal high energy evolution kernel must be selfdual.Comment: Talk given at DIS05, April 2005, Madiso

Spatial Resolution of Double-Sided Silicon Microstrip Detectors for the PAMELA Apparatus

The PAMELA apparatus has been assembled and it is ready to be launched in a satellite mission to study mainly the antiparticle component of cosmic rays. In this paper the performances obtained for the silicon microstrip detectors used in the magnetic spectrometer are presented. This subdetector reconstructs the curvature of a charged particle in the magnetic field produced by a permanent magnet and consequently determines momentum and charge sign, thanks to a very good accuracy in the position measurements (better than 3 um in the bending coordinate). A complete simulation of the silicon microstrip detectors has been developed in order to investigate in great detail the sensor's characteristics. Simulated events have been then compared with data gathered from minimum ionizing particle (MIP) beams during the last years in order to tune free parameters of the simulation. Finally some either widely used or original position finding algorithms, designed for such kind of detectors, have been applied to events with different incidence angles. As a result of the analysis, a method of impact point reconstruction can be chosen, depending on both the particle's incidence angle and the cluster multiplicity, so as to maximize the capability of the spectrometer in antiparticle tagging.Comment: 28 pages, 18 figures, submitted to Nuclear Instruments and Methods in Physics Research

Hubungan Tingkat Stres, Asupan Natrium, Dan Riwayat Makan Dengan Kejadian Stroke

Stroke is a condition of the local neurological disorder that occurs suddenly, causing blood supply into the brain tissue stop and also causing impaired brain function. There are many causal factors that lead to stroke such as age, stress, natrium consumption, and food history. This study aims to analyze the relation between stress level, natrium consumption, and food history with the incidence of stroke in among stroke outpatients aged ≥ 45 years. This is an analytic observational study using case control design in Neural Poly of Airlangga University Hospital. The population of case group was stroke outpatients aged ≥ 45 years while control group was outpatients aged ≥ 45 years who didn't have stroke. The sample was 11 patients for each group and were taken using simple random sampling technique. Relation among variables were analyzed using Chi-Square test. The result of this study showed that there is signifi cant relation between natrium consumption level (p = 0,032; OR = 0,083) and food history (p = 0,003; OR = 45,000) with the incidence of stroke. There is no signifi cant relation between stress level (p = 1,000) with the incidence of stroke. It is necessary to give the information about natrium food source and healthy diet in order to prevent the occurrence of stroke

Fragmentation Function Method for Charge Asymmetry Measurements in \e^+e^- Collisions

We propose a method for measuring the hadron charge asymmetry in \ee collisions which is based upon the fragmentation function formalism, and is largely independent of modelling of fragmentation effects. Furthermore, in this method, QCD radiative corrections can be accounted for in a systematic way.Comment: 11 pages, 4 figures, Latex, CERN-TH.7212/9

Parental Assistance on Electronic Interactive Games (Games) for Children Aged 3-6 Years During Learn From Home

The objectives of this study include: to find out whether Tangram Media Against Children’s Cognitive Ability to Recognize Geometry Shapes. The research method that researchers use is a quantitative method. This research is included in the regression research. From the results of the research conducted, the following results were obtained: Tangram media had an effect on the ability to recognize geometric shapes. Which is marked by the increase in the result of childrens’s learning tests in stage 2, namely at the post test stage, as well as the results obtained from the coefficient table which shows Y = 57,725 + 1,121. A cobstant of 57,725 states that if there is not tangram media the ability to recognize children’s geometric shapes of 57,725 states that if there is no tagram media has a positive positive effect on the ability to recognize geometric shapes,meaning that the better the learning media, the greater or better the ability to recognize geometric shapes. The independent variable (Vx) has an effect of 0.585 or 58.5 % on the dependent variable (Vy) and the rest is influenced by other variables not discussed in this study. What can be interpreted also that the tangram media has an effect of 0.585 or 58.5% on the ability to recognize geometric shapes. &nbsp
