On Necessary and Sufficient Conditions for Preserving Convergence Rates to Equilibrium in Deterministically and Stochastically Perturbed Differential Equations with Regularly Varying Nonlinearity

This paper develops necessary and sufficient conditions for the preservation of asymptotic convergence rates of deterministically and stochastically perturbed ordinary differential equations with regularly varying nonlinearity close to their equilibrium. Sharp conditions are also established which preserve the asymptotic behaviour of the derivative of the underlying unperturbed equation. Finally, necessary and sufficient conditions are established which enable finite difference approximations to the derivative in the stochastic equation to preserve the asymptotic behaviour of the derivative of the unperturbed equation, even though the solution of the stochastic equation is nowhere differentiable, almost surely

The FLUKA Model of IR8

The study of machine induced background (MIB), the radiation environment and beam dynamics of the LHC requires a detailed model of the machine tunnel, elements and electromagnetic fields. In this note, a specially created model of IR8 in FLUKA is described, including the tunnel, vacuum chambers, magnets, collimators, injection elements and shielding. The inclusion of all relevant machine elements in the LSS of IR8 results in a very flexible model suitable for a large variety of calculations and studies. The validation of the model is discussed, and some example applications described

Knowledge mobilization in bridging patient‐practitioner‐researcher boundaries : a systematic integrative review

Aim To review when, how, and in what context knowledge mobilization (KMb) has crossed patient‐practitioner‐researcher boundaries. Background KMb is essential in contemporary health care, yet little is known about how patients are engaged. Design Integrative review. Data sources Ten academic databases and grey literature. Review methods We followed integrative review methodology to identify publications from 2006–2019 which contributed to understanding of cross‐boundary KMb. We extracted data using a bespoke spreadsheet and the Template for Intervention Description and Replication (TIDieR) framework. We used meta‐summary to organize key findings. Results Thirty‐three papers collectively provide new insights into ‘when’ and ‘how’ KMb has crossed patient‐researcher‐practitioner boundaries and the impact this has achieved. Knowledge is mobilized to improve care, promote health, or prevent ill health. Most studies focus on creating or re‐shaping knowledge to make it more useful. Knowledge is mobilized in small community groups, in larger networks, and intervention studies. Finding the right people to engage in activities is crucial, as activities can be demanding and time‐consuming. Devolving power to communities and using local people to move knowledge can be effective. Few studies report definitive outcomes of KMb. Conclusion Cross‐boundary KMb can and does produce new and shared knowledge for health care. Positive outcomes can be achieved using diverse public engagement strategies. KMb process and theory is an emerging discipline, further research is needed on effective cross‐boundary working and on measuring the impact of KMb. Impact This review provides new and nuanced understandings of how KMb theory has been used to bridge patient‐researcher‐practitioner boundaries. We have assessed ‘how’, ‘when’, and in what context patients, practitioners and researchers have attempted to mobilize knowledge and identified impact. We have developed a knowledge base about good practice and what can and potentially should be avoided in cross‐boundary KMb

Non-global logarithms in inter-jet energy flow with kt clustering requirement

Recent work in inter-jet energy flow has identified a class of leading logarithms previously not considered in the literature. These so-called non-global logarithms have been shown to have significant numerical impact on gaps-between-jets calculations at the energies of current particle colliders. Here we calculate, at fixed order and to all orders, the effect of applying clustering to the gluonic final state responsible for these logarithms for a trivial colour flow 2 jet system. Such a clustering algorithm has already been used for experimental measurements at HERA. We find that the impact of the non-global logarithms is reduced, but not removed, when clustering is demanded, a result which is of considerable interest for energy flow observable calculations.Comment: 13 pages, 4 figure

The 2mrad horizontal crossing angle IR layout for a TeV ILC

The current status of the 2mrad crossing angle layout for the ILC is reviewed. The scheme developed in the UK and France is described and the performance discussed for a TeV machine. Secondly, the scheme developed at SLAC and BNL is then studied and modified for a TeV machine. We find that both schemes can handle the higher energy beam with modifications, and share many common features.Comment: The proceedings of the 2005 International Linear Collider Workshop, March 2005. 4 pages, 5 figure

Integration of the Forward Detectors inside the LHC Machine

Several forward detectors have been installed in the LHC long straight sections located on each side of the experimental caverns. Most of these detectors have been designed by the LHC experiments to study the forward physics while some of them are dedicated to the measurement of the LHC luminosity. The integration and the installation of the forward detectors have required an excellent coordination between the experiments and the different CERN groups involved into the design and the installation of the LHC accelerator. In some cases the integration of these detectors has required a modification of the standard beam lines in order to maximise their physics potential. Finally, additional systems have been installed in the LHC tunnel to ensure the operation of the forward detectors in a high radiation environment

A Quantum-Bayesian Route to Quantum-State Space

In the quantum-Bayesian approach to quantum foundations, a quantum state is viewed as an expression of an agent's personalist Bayesian degrees of belief, or probabilities, concerning the results of measurements. These probabilities obey the usual probability rules as required by Dutch-book coherence, but quantum mechanics imposes additional constraints upon them. In this paper, we explore the question of deriving the structure of quantum-state space from a set of assumptions in the spirit of quantum Bayesianism. The starting point is the representation of quantum states induced by a symmetric informationally complete measurement or SIC. In this representation, the Born rule takes the form of a particularly simple modification of the law of total probability. We show how to derive key features of quantum-state space from (i) the requirement that the Born rule arises as a simple modification of the law of total probability and (ii) a limited number of additional assumptions of a strong Bayesian flavor.Comment: 7 pages, 1 figure, to appear in Foundations of Physics; this is a condensation of the argument in arXiv:0906.2187v1 [quant-ph], with special attention paid to making all assumptions explici

CONTEMPORARY CHALLENGES FACING THE AUSTRALIAN JUDICIARY: AN EMPIRICAL INTERRUPTION

© 2019 Melbourne University Law Review. All rights reserved. The structures that regulate and support the Australian judiciary reflect and serve the traditional judicial values of independence, impartiality and the rule of law. Yet modern society places emphasis on an additional range of values that are expected of government and public institutions. These contemporary values include diversity, transparency, accountability and efficiency. Reforms to introduce regulatory and support structures that prioritise and facilitate these values in the judicial arm has proved challenging and, sometimes, contentious. This article reports on a survey of Australian judicial officers (n = 142) from across different jurisdictions. Participants were asked what they considered to be the most pressing challenges that face the various levels of the Australian judiciary, and whether the current regulatory and support environment achieves international best practice. The responses provide a nuanced picture of the state of the modern Australian judiciary as it appears to those within it. The study facilitates an understanding of the degree to which judicial officers are satisfied with the current legal and regulatory framework and, where they are dissatisfied, the nature of their disquiet. While not seeking to offer complete resolutions to the many issues canvassed, the data and analysis presented in this article serve as an interruption to regulatory and academic studies of the Australian judiciary, with the potential to illuminate and re-orientate the reform conversation in light of the judicial perspective on these various issues
