CP-violation reach of an electron capture neutrino beam

This article extends the work of Bernabeu and Espinoza by examining the CP-violation reach of a $^{150}$Dy electron capture beam through the variation of the two Lorentz boosts, the number of useful electron capture decays, the relative run time of each boost and the number of atmospheric backgrounds. The neutrinos are assumed to be sourced at CERN with an upgraded SPS and are directed towards a 440 kton Water Cerenkov detector located at the Canfranc laboratory. Two large `CP-coverage' choices for the boost pairings are found; a $\delta$-symmetrical coverage for $(\gamma_{1}, \gamma_{2})$ = (280, 160) and an $\delta$-asymmetric coverage for $(\gamma_{1}, \gamma_{2})$ = (440,150). With a nominal useful decay rate of $N_{\rm ions} = 10^{18}$ ions per year, the $\delta$-symmetric setup can rule out CP-conservation down to $\sin^{2}2\theta_{13} = 3\cdot 10^{-4}$. To reach $\sin^{2}2\theta_{13} = 1\cdot 10^{-3}$ for both $\delta 0$ requires a useful decay rate of $N_{\rm ions} = 6\cdot 10^{17}$ ions per year.Comment: 18 pages, 11 figures.

The foundations of a nation : framing Pakistan from 1940-1971 through international relations theory and postcolonialism

This paper explores the emerging integration of international relations theory with postcolonial scholarship and uses Pakistan’s state formation and history as a case study. It is argued that international relations theory privileges European experiences and history, which results in inaccurate assumptions about the outcomes of colonialism and origins of postcolonial independence. Pakistan’s unique development as a state founded on ideology and build out of an imperial/colonial system offers an opportunity for destabilizing Eurocentrism in international studies. Rather than favoring a singular outcome or conclusion, this paper demonstrates the plurality necessary for an inclusive historical analysis of state-power.Asian StudiesGlobal Policy Studie

Fear and Loathing of the Corruption Perception Index: Does Transparency International Penalize Press Freedom?

Depuis que la gouvernance compte, l’Indice de perception de la corruption construit par Transparency International (TI) est devenu l’indicateur le plus influent dans son domaine. Chaque année, un classement est ainsi établi, pointant du doigt les pays perçus comme les plus corrompus par les experts de TI. Cet indice est un outil puissant de lutte contre le fléau de la corruption, permettant effectivement de mettre une réelle pression politique sur des régimes « mal gouvernés ». L’influence de ce classement sur l’économie des pays concernés peut être importante, rendant parfois plus difficile l’accès aux financements, qu’il s’agisse de l’aide internationale ou des investissements directs étrangers. Bien souvent, il s’agit d’une double peine pour des populations déjà victimes au quotidien de services publics gangrenés par la corruption et le clientélisme. La mesure de la corruption, à l’image des différents outils mis en place pour évaluer la gouvernance, est une mesure qualitative, issue de perceptions. Comme toute perception, elle est sujette à la disponibilité de l’information et subit l’influence des médias. Nos analyses ont montré que le niveau de liberté de la presse pouvait avoir une influence importante sur ces perceptions, pénalisant les jeunes démocraties et l’ouverture progressive des médias. Transparency International’s annual Corruption Perception Index (CPI) has become the single most effective advocacy tool in the global fight against fraud, embezzlement and other abuses of public office for private gain. Countries relegated to the bottom tier of the CPI rankings are not only embarrassed (usually), but penalized financially, as the stigma makes it harder to secure aid and investment. For any multilateral loan officer or multinational plant-siting team, checking a country’s CPI rating is now basic due diligence. As well it should be: Corruption is a development scourge, acting as a stubborn brake on growth, a regressive tax on the poor, and - often - a corrosively effective enemy of democratization. Corruption assessment, not unlike governance assessment tools, is qualitative and the result of perceptions. Therefore, it suffers from the influence of information availability and media freedom. Our analysis, demonstrated that the media freedom extent may have a strong influence on corruption perceptions, penalizing young democracies and progressive media aperture.(Full text in french)

Subsonic flight test evaluation of a propulsion system parameter estimation process for the F100 engine

Integrated engine-airframe optimal control technology may significantly improve aircraft performance. This technology requires a reliable and accurate parameter estimator to predict unmeasured variables. To develop this technology base, NASA Dryden Flight Research Facility (Edwards, CA), McDonnell Aircraft Company (St. Louis, MO), and Pratt & Whitney (West Palm Beach, FL) have developed and flight-tested an adaptive performance seeking control system which optimizes the quasi-steady-state performance of the F-15 propulsion system. This paper presents flight and ground test evaluations of the propulsion system parameter estimation process used by the performance seeking control system. The estimator consists of a compact propulsion system model and an extended Kalman filter. The extended Laman filter estimates five engine component deviation parameters from measured inputs. The compact model uses measurements and Kalman-filter estimates as inputs to predict unmeasured propulsion parameters such as net propulsive force and fan stall margin. The ability to track trends and estimate absolute values of propulsion system parameters was demonstrated. For example, thrust stand results show a good correlation, especially in trends, between the performance seeking control estimated and measured thrust

Hamiltonian structure of thermodynamics with gauge

The state of a thermodynamic system being characterized by its set of extensive variables $q^{i}(i=1,...,n) ,$ we write the associated intensive variables $\gamma_{i},$ the partial derivatives of the entropy $S(q^{1},...,q^{n}) \equiv q_{0},$ in the form $\gamma_{i}=-p_{i}/p_{0}$ where $p_{0}$ behaves as a gauge factor. When regarded as independent, the variables $q^{i},p_{i}(i=0,...,n)$ define a space $\mathbb{T}$ having a canonical symplectic structure where they appear as conjugate. A thermodynamic system is represented by a $n+1$-dimensional gauge-invariant Lagrangian submanifold $\mathbb{M}$ of $\mathbb{T}.$ Any thermodynamic process, even dissipative, taking place on $\mathbb{M}$ is represented by a Hamiltonian trajectory in $\mathbb{T},$ governed by a Hamiltonian function which is zero on $\mathbb{M}.$ A mapping between the equations of state of different systems is likewise represented by a canonical transformation in $\mathbb{T}.$ Moreover a natural Riemannian metric exists for any physical system, with the $q^{i}$'s as contravariant variables, the $p_{i}$'s as covariant ones. Illustrative examples are given.Comment: Proofs corrections latex vali.tex, 1 file, 28 pages [SPhT-T00/099], submitted to Eur. Phys. J.

Bridge 2018 Information Literacy Curriculum Report

A uniform curriculum has been in place in Bridge Information Literacy (IL) sessions since Fall 2015. To assess the curriculum and student learning, multiple evaluations are implemented: a student end-of-class evaluation; a faculty end-of-Bridge evaluation; and an in-class worksheet. This report summarizes student performance in Bridge as well as student and faculty evaluation responses

A First Exposure to Statistical Mechanics for Life Scientists

Statistical mechanics is one of the most powerful and elegant tools in the quantitative sciences. One key virtue of statistical mechanics is that it is designed to examine large systems with many interacting degrees of freedom, providing a clue that it might have some bearing on the analysis of the molecules of living matter. As a result of data on biological systems becoming increasingly quantitative, there is a concomitant demand that the models set forth to describe biological systems be themselves quantitative. We describe how statistical mechanics is part of the quantitative toolkit that is needed to respond to such data. The power of statistical mechanics is not limited to traditional physical and chemical problems and there are a host of interesting ways in which these ideas can be applied in biology. This article reports on our efforts to teach statistical mechanics to life science students and provides a framework for others interested in bringing these tools to a nontraditional audience in the life sciences.Comment: 27 pages, 16 figures.
