TL;DR: It is demonstrated that the electrical fluctuations in a single-Electron transistor can be accurately measured on all relevant frequencies using a nearby quantum point contact for on-chip real-time detection of the current pulses in the single-electron device.
Abstract: Electron transport in nanoscale structures is strongly influenced by the Coulomb interaction that gives rise to correlations in the stream of charges and leaves clear fingerprints in the fluctuations of the electrical current. A complete understanding of the underlying physical processes requires measurements of the electrical fluctuations on all time and frequency scales, but experiments have so far been restricted to fixed frequency ranges, as broadband detection of current fluctuations is an inherently difficult experimental procedure. Here we demonstrate that the electrical fluctuations in a single-electron transistor can be accurately measured on all relevant frequencies using a nearby quantum point contact for on-chip real-time detection of the current pulses in the single-electron device. We have directly measured the frequency-dependent current statistics and, hereby, fully characterized the fundamental tunnelling processes in the single-electron transistor. Our experiment paves the way for future investigations of interaction and coherence-induced correlation effects in quantum transport.

TL;DR: In this article, the authors present a set of hypotheses on the determinants and effects of situational consumer reactance against loyalty programs and test them on the basis of 388 face-to-face interviews with bookstore customers.
Abstract: Purpose – Although relationship marketing has developed into the prevailing marketing paradigm, it frequently encounters resistance from the demand side. Both management practitioners and academics indicate that at least some consumers show reactance against loyalty programs, i.e. against tactical instruments of relationship marketing. Nevertheless, relationship marketing has widely neglected reactance theory. This paper attempts to close this gap.Design/methodology/approach – Based on the fundamental principles of loyalty programs and reactance theory the paper presents a set of hypotheses on the determinants and effects of situational consumer reactance against loyalty programs. It tests these hypotheses on the basis of 388 face‐to‐face interviews with bookstore customers. These interviews include a between‐subject manipulation on the reactance effect of economic, social‐psychological, and contractual bonding potentials. To test the proposed hypotheses, the paper applies structural equation modeling wit...

TL;DR: The implementation of a search for gravitational waves from compact binary coalescences in LIGO and Virgo data is described and it is demonstrated that the signal consistency tests are capable of mitigating the effect of non-Gaussian noise and providing a sensitivity comparable to that achieved in Gaussian noise.
Abstract: We describe the implementation of a search for gravitational waves from compact binary coalescences in LIGO and Virgo data. This all-sky, all-time, multidetector search for binary coalescence has been used to search data taken in recent LIGO and Virgo runs. The search is built around a matched filter analysis of the data, augmented by numerous signal consistency tests designed to distinguish artifacts of non-Gaussian detector noise from potential detections. We demonstrate the search performance using Gaussian noise and data from the fifth LIGO science run and demonstrate that the signal consistency tests are capable of mitigating the effect of non-Gaussian noise and providing a sensitivity comparable to that achieved in Gaussian noise.

TL;DR: In this paper, the authors describe the calibration of the instruments in the S5 data set, including measurement techniques and uncertainty estimation, for the LIGO data set of the fifth science run (S5).
Abstract: The Laser Interferometer Gravitational Wave Observatory (LIGO) is a network of three detectors built to detect local perturbations in the space–time metric from astrophysical sources. These detectors, two in Hanford, WA and one in Livingston, LA, are power-recycled Fabry-Perot Michelson interferometers. In their fifth science run (S5), between November 2005 and October 2007, these detectors accumulated one year of triple coincident data while operating at their designed sensitivity. In this paper, we describe the calibration of the instruments in the S5 data set, including measurement techniques and uncertainty estimation.

TL;DR: In this article, a tsunami early warning information system is proposed to meet the requirements of small-scale, heterogeneous and complex coastal urban systems, where data, methods and results from engineering, remote sensing and social sciences are interlinked and provide comprehensive information for disaster risk assessment, management and reduction.
Abstract: . Extreme natural events, like e.g. tsunamis or earthquakes, regularly lead to catastrophes with dramatic consequences. In recent years natural disasters caused hundreds of thousands of deaths, destruction of infrastructure, disruption of economic activity and loss of billions of dollars worth of property and thus revealed considerable deficits hindering their effective management: Needs for stakeholders, decision-makers as well as for persons concerned include systematic risk identification and evaluation, a way to assess countermeasures, awareness raising and decision support systems to be employed before, during and after crisis situations. The overall goal of this study focuses on interdisciplinary integration of various scientific disciplines to contribute to a tsunami early warning information system. In comparison to most studies our focus is on high-end geometric and thematic analysis to meet the requirements of small-scale, heterogeneous and complex coastal urban systems. Data, methods and results from engineering, remote sensing and social sciences are interlinked and provide comprehensive information for disaster risk assessment, management and reduction. In detail, we combine inundation modeling, urban morphology analysis, population assessment, socio-economic analysis of the population and evacuation modeling. The interdisciplinary results eventually lead to recommendations for mitigation strategies in the fields of spatial planning or coping capacity.
