Varying Mass

In TEM image formation, the observed contrast variations within thin sections result from differential electron scattering within microregions of varying mass thickness. It is possible to utilize these electron scattering properties to obtain objective information regarding various specimen parameters (1, 2, 3).A pragmatic, empirical approach is described which enables a microscopist to perform physical measurements of thickness of thin sections and estimates of local mass, volume, density and, possibly, molecular configurations within thin sections directly in the microscope. A Faraday cage monitors the transmitted electron beam and permits measurements of electron beam intensities.

The Mass Media

This study examines the Political News Analysis of the Sovereignty of the People's Sovereignty on Eradicating Corruption as the Independence of the Mass Media in Proclaiming the Performance of the Jokowi-JK Government which focuses on 1 year of its administration (20 October 2014 October 20 2015). This research is based on two things, namely: first, how is the analysis of the political news regarding Corruption Eradication in the local mass media (Kedaulatan Rakyat) in reporting on the performance of the Jokowi-JK government; second, how the independence of the local mass media in reporting on the performance of the Jokowi-JK government in the area of ??corruption eradication. Media independence is seen from the method of Qualitative Approach with Critical Paradigm namely Critical Discourse Analysis; using Teun A. van Dijk's Model Analysis of text production involving aspects of cognition and social context.  The production of text in the political news regarding the Eradication of Corruption in Judging the Performance of the Jokowi-JK Government presented by the Kedaulatan Rakyat SKH is a strong text structure. The Kedaulatan Rakyat Daily Newspaper is able to provide detailed Semantic Structure and more coherent relationships between words / sentences. In addition, the Kedaulatan Rakyat Daily Newspaper minimizes graphics and metaphor as rhetorical elements so as to be able to present more real and factual news. starting from text, social cognition and social context. The news on SKH Kedaulatan Rakyat is able to present the factual news objectivity in accordance with the truth and relevance. Not only that, the objectivity of the news about justice is able to be fulfilled by the People's Sovereignty SKH by presenting balanced news and explaining it more neutral without the support of the mass media.

Invariant submodel of rank 2 on the subalgebra consisting of the sum of transfers for hydrodynamic equations with the equation of state in the form of pressure as the sum of density and entropy functions, is presented. In terms of the Lagrangian coordinates from condition of nonhyperbolic submodel solutions depending on the four essential constants are obtained. For simplicity, we consider the solution depending on two constants. The trajectory of particles motion, the motion of parallelepiped of the same particles are studied using the Maple.

Full Classification

AbstractIn this paper, we continue the study of powerfully nilpotent groups. These are powerful p-groups possessing a central series of a special kind. To each such group, one can attach a powerful nilpotency class that leads naturally to the notion of a powerful coclass and classification in terms of an ancestry tree. In this paper, we will give a full classification of powerfully nilpotent groups of rank 2. The classification will then be used to arrive at a precise formula for the number of powerfully nilpotent groups of rank 2 and order {p^{n}}. We will also give a detailed analysis of the ancestry tree for these groups. The second part of the paper is then devoted to a full classification of powerfully nilpotent groups of order up to {p^{6}}.

Abstract We derive explicit formulae to compute the a and c central charges of four dimensional $$ \mathcal{N} $$ N = 2 superconformal field theories (SCFTs) directly from Coulomb branch related quantities. The formulae apply at arbitrary rank. We also discover general properties of the low-energy limit behavior of the flavor symmetry of $$ \mathcal{N} $$ N = 2 SCFTs which culminate with our $$ \mathcal{N} $$ N = 2 UV-IR simple flavor condition. This is done by determining precisely the relation between the integrand of the partition function of the topologically twisted version of the 4d $$ \mathcal{N} $$ N = 2 SCFTs and the singular locus of their Coulomb branches. The techniques developed here are extensively applied to many rank-2 SCFTs, including new ones, in a companion paper.This manuscript is dedicated to the memory of Rayshard Brooks, George Floyd, Breonna Taylor and the countless black lives taken by US police forces and still awaiting justice. Our hearts are with our colleagues of color who suffer daily the consequences of this racist world.
