CP violating supersymmetric contributions to the electroweak ρ\rho parameter

Effects of CP violation on the supersymmetric electroweak correction to the $\rho$ parameter are investigated. To avoid the EDM constraints, we require that arg$(\mu)<10^{-2}$ and the non-universal trilinear couplings $A_f=(0,0,A_0)$ and also assume that gluinos are heavier than 400 GeV. The CP phase $\phi_t=$ arg($A_0$) leads to large enhancement of the relative mass splittings between $\tilde{t}_2$ and $\tilde{b}_L(\tilde{t}_1)$, which in turn reduces the one-loop contribution of the stop and sbottom to $\Delta \rho$. For small $\tan \beta$, such a CP violating effect is prominent. We also study how much the two-loop gluon and gluino contributions are affected by the CP phase. Possible contributions to the $\rho$ parameter arising from the Higgs sector with CP violation are discussed.Comment: 14 pages, Revtex, 4 eps figures, to appear in Phys. Rev. D (Rapid Comm.

AN INTERNATIONAL STUDY ON DIFFERENT FACTORS OF OPERATING SCHOOL TEMPORARY POSITION: FOCUSING ON CASES OF KOREA, HOLLAND, GERMANY, SWEDEN

The necessities of strategies for the labor force in the school temporary position are superior in education practice. In the perspective of government, a new paradigm and method for them such as employment stability, better treatment and fewer tasks have been sought. However, the information for them is not enough. While seeing the main issue to manage an temporary workers and the feature of the system for them in schools of Holland, Germany and Sweden, this study shows an effective plan for not only the labor force in the school temporary workers and but their skill development. Based on the result of a plan in education office, supporting office, and schools this study proposes the political and institutional method to revitalize the efficient management of temporary workers in school.&nbsp

ECONOMICAL EFFECT OF ON-THE-JOB TRAINING: USING KOREAN FIRM PANEL DATA

The study aims to investigate the economic effect of firm on-the-job training using a panel data in Korea, improving analysis data, method, and study model of a precedent study. To accomplish the object of this study, the panel analysis was applied to analyze using a Korea Investors Service (KIS), Human Capital Corporate Panel (HCCP) and Workplace Panel Survey (WPS) data. The results of this study show that positive effect firm on-the-job training on firm’s productivity. Based on the results of this study, government should need to make a policy development to reinforcement investment on firm on-the-job training at the national level. And it was drawn in a conclusion to need not avoid but continuous investment on firm on-the-job training at the company level

Feature Selection and Non-Euclidean Dimensionality Reduction: Application to Electrocardiology.

Heart disease has been the leading cause of human death for decades. To improve treatment of heart disease, algorithms to perform reliable computer diagnosis using electrocardiogram (ECG) data have become an area of active research. This thesis utilizes well-established methods from cluster analysis, classification, and localization to cluster and classify ECG data, and aims to help clinicians diagnose and treat heart diseases. The power of these methods is enhanced by state-of-the-art feature selection and dimensionality reduction. The specific contributions of this thesis are as follows. First, a unique combination of ECG feature selection and mixture model clustering is introduced to classify the sites of origin of ventricular tachycardias. Second, we apply a restricted Boltzmann machine (RBM) to learn sparse representations of ECG signals and to build an enriched classifier from patient data. Third, a novel manifold learning algorithm is introduced, called Quaternion Laplacian Information Maps (QLIM), and is applied to visualize high-dimensional ECG signals. These methods are applied to design of an automated supervised classification algorithm to help a physician identify the origin of ventricular arrhythmias (VA) directed from a patient's ECG data. The algorithm is trained on a large database of ECGs and catheter positions collected during the electrophysiology (EP) pace-mapping procedures. The proposed algorithm is demonstrated to have a correct classification rate of over 80% for the difficult task of classifying VAs having epicardial or endocardial origins.PhDElectrical Engineering: SystemsUniversity of Michigan, Horace H.

Quantum Effects on the Formation of Negative Hydrogen Ion by Polarization Electron Capture in Partially Ionized Dense Hydrogen Plasmas

The quantum effects on the formation of the negative hydrogen ion (H-) by the polarization electron capture process are investigated in partially ionized dense hydrogen plasmas. It is shown that the quantum effect strongly suppresses the electron capture radius as well as the cross section for the formation of the negative hydrogen ion. In addition, it has been found that the electron capture position is receded from the center of the projectile with decreasing the quantum effect of the plasma

Quantum and plasma screening effects on the Wannier threshold law for the double-electron escape in strongly coupled semiclassical plasmas

The quantum and plasma screening effects on the Wannier threshold law for the double-electron escape are investigated in strongly coupled semiclassical plasmas. The renormalized electron charge and Wannier exponent are obtained by considering the equation of motion in the Wannier configuration with the screened pseudopotential model as functions of the de Broglie wavelength, Debye length, and charge of the residual ion. It is shown that the renormalized electron charge significantly increases with an increase in the de Broglie wavelength, especially for small radial distances. It is also shown that the quantum effects enhance the Wannier exponent for the double-electron escape. In addition, the quantum effect on the Wannier threshold law is found to be more important than the plasma screening effect in strongly coupled semiclassical plasmas
