Application of a Revised Moliere Theory to the Description of the Landau-Pomeranchuk Effect

Using the Coulomb corrections to some important parameters of a revised Moliere multiple scattering theory, we have obtained analytically and numerically the Coulomb corrections to the quantities of the Migdal theory of the Landau-Pomeranchuk (LPM) effect for sufficiently thick targets. We showed that the Coulomb correction to the spectral bremsstrahlung rate of this theory allows completely eliminating the discrepancy between the theory and experiment at leastfor high Z experimental targets.Comment: PDFLaTeX, 9 pages, 6 Tables, and 1 Figure.

Nobody Wants to Eat Them Alive:” Ethical Dilemmas and Dual Media Narratives on Domestic Rabbits as Pets and Commodity

Using semiotic analysis, this study explores changes occurring in the societal perception of rabbits as farm animals as juxtaposed to their increasing popularity as domestic companions. This study is based on a preliminary hypothesis that rabbits are increasingly perceived and portrayed in media as domestic companion animals similar to cats and guinea pigs, which challenges a parallel narrative that views rabbits as commodities for their meat and fur. Operating within a theoretical framework that considers news media as both socially constructed reality and recorded history, the study examines the dynamics of change in numbers of coded news narratives drawn as a 1000-piece convenience sample from a database of news stories published worldwide between 1990 and 2011

On the stratifications of 2-qubits X-state space

The 7-dimensional family $\mathfrak{P}_X$ of so-called mixed X-states of 2-qubits is considered. Two types of stratification of 2-qubits $X-$state space, i.e., partitions of $\mathfrak{P}_X\,$ into orbit types with respect to the adjoint group actions, one of the global unitary group $G_X \subset SU(4)$ and another one under the action of the local unitary group $LG_X \subset G_X$, is described. The equations and inequalities in the invariants of the corresponding groups, determining each stratification component, are given

Using found object visuals to crystallize learning

To help learners consolidate learning before the end of a classroom session, they can be instructed to use found objects at hand to illustrate the most salient ideas they are taking away. Such deliberate veering from verbal language alone provides easy entry to challenging material and a way to capture knowledge using mental channels other than typical verbal-linguistic ones—making learning more likely to be transformative and lasting

Application of binary logistic regression in credit scoring

Nowadays, demand for loan products is growing day by day. Also, loan applicants have become more demanding, than they were before. They want to receive the response from bank as soon as possible. In order to resist the growing competition banks develop new quantification techniques which accelerate and automate the decision making process. One of these techniques is credit scoring. Credit Scoring is one of the most widely used instruments which is applied by lenders decide whether to approve or reject the loan application. In this Master’s thesis an overview of credit scoring is given. The most essential objective of this thesis is to show the application of logistic regression in Credit score models. Other methods of credit scoring will also be noted, but not in extensive detail. The study ends with a practical application of logistic regression for a credit scoring model on real data of loan applicants
