Studies of charmed states in amplitude analyses at LHCb

Amplitude analysis is a powerful tool to study the properties of intermediate resonances produced in the decays of B mesons. At LHCb we have studied B+ decays to X(3872) K+, where X(3872) decays to J/psi pi+ pi-, to determine the quantum numbers of the X(3872), and B+ decays to proton anti-proton K+ to learn more about (charm anti-charm) to proton anti-proton transitions. We also exploit the spin of the J/psi to perform amplitude analyses of the decays B0_s to J/psi pi+ pi-, B0_s to J/psi K+ K-, B0 to J/psi pi+ pi-, and B0 to J/psi K+ K-. Our results use 1.0 inverse femtobarn of data taken in 2011 from 7 TeV proton-proton collisions, provided by the LHC.Comment: 9 pages, 3 figures, to appear in the proceedings of The 6th International Workshop on Charm Physics (CHARM 2013

Searches for CP Violation in charm at LHCb

LHCb has collected the world's largest sample of charmed hadrons. This sample is used to search for direct and indirect CP Violation in charm. Recent and updated measurements from several decay modes are presented.Comment: To be published in the proceedings of CHARM-2015, Detroit, MI, 18-22 May 201

Globalization and International Public Finance

This paper examines the effect of reduced transaction costs in the international trading of assets on the ability of governments to issue debt. We examine a model in which governments care about the welfare of their citizens, and thus are more inclined to default if a large proportion of their debt is held by foreigners. Reductions in transaction costs make it easier for domestic citizens to share risk by selling debt to foreigners. This may increase tendencies for governments to default, and thus raise their cost of credit and reduce welfare. We find that even in the absence of transaction costs, home bias in placement of government debt may persist, because in the presence of default risk the return on government debt is correlated with the tax burden required to pay the debt. Asset inequality may reduce this home bias, and by increasing foreign ownership, increase incentives for default. Finally, if foreign creditors are less risk averse than domestic creditors, there may be one equilibrium in which domestic creditors hold the asset and default risk is low, and another in which foreign creditors hold the asset and default risk is high.

Track My Hoist

Construction sites all over the world rely on hoist lifts for transporting material and workers at the job site. Despite being such an integral part of construction projects, there is currently no tool to track the use of this critical and highly necessary piece of equipment at the construction site. The purpose of this project is to design a systemthat would enable the managers and employees of construction companies to efficiently track and manage the hoist lifts at their sites. Efficient tracking and management of the lifts would result in savings of cost, time, and energy for the construction companies. Such improvements would also help boost worker morale, which would consequently boost productivity. Over the course of this project the team has designed an interactive yet intuitive software application that helps effectively track and manage hoist lifts on construction sites

Comparison of Different Additive Manufacturing Methods Using Optimized Computed Tomography

Additive manufacturing (AM) allows for fast fabrication of three dimensional objects with the possibility of use of considerably less resources than would be the case in traditional manufacturing. AM is a fast and cost effective method which boasts the ability to produce components with a previously unachievable level of geometric complexity in end user industrial applications in areas such as the aerospace and automotive industries. However these processes currently lack reproducibility and repeatability with some ‘prints’ having a high rate requiring rework or even scrapping. It is therefore imperative that robust quality systems can be implemented such that the waste level of these processes can be eliminated or decreased. This study presents an artefact that has been optimised for characterisation using computed tomography (CT) with representative AM internal channels and structures. Furthermore the optimisation of the CT acquisition conditions for this artefact is presented in light of analysis of form, internal feature dimensions and position and material porosity

Sustainability and Replicability of Multiple-Use Water Systems (MUS)

The concept of multiple-use water services and systems (MUS) has received increasingattention in international water and development fora and has emerged as a promising wayto enhance the social and gender equity and productivity of water systems designed forsingle use, e.g. for irrigation or water supply. In Nepal, several MUS models have beenpiloted and implemented for more than a decade by the International DevelopmentEnterprises (iDE) and a few other development organizations. Whereas the short-termbenefits of these systems on gender relationships, women's empowerment, nutrition andhealth have been documented, the sustainability and resilience of these systems has not yetbeen analyzed. The latter is the focus of the research study presented in this report, whichwas conducted by the International Water Management Institute (IWMI) in Western Nepalas part of the USAID-funded Market Access and Water Technology for Women (MAWTW)project

Long-term and persistent vocal plasticity in adult bats.

Bats exhibit a diverse and complex vocabulary of social communication calls some of which are believed to be learned during development. This ability to produce learned, species-specific vocalizations - a rare trait in the animal kingdom - requires a high-degree of vocal plasticity. Bats live extremely long lives in highly complex and dynamic social environments, which suggests that they might also retain a high degree of vocal plasticity in adulthood, much as humans do. Here, we report persistent vocal plasticity in adult bats (Rousettus aegyptiacus) following exposure to broad-band, acoustic perturbation. Our results show that adult bats can not only modify distinct parameters of their vocalizations, but that these changes persist even after noise cessation - in some cases lasting several weeks or months. Combined, these findings underscore the potential importance of bats as a model organism for studies of vocal plasticity, including in adulthood

Improving Collaboration between Pharmacists and Physicians

Physicians and pharmacists have differing but complementary roles that can optimize patient care when structured effectively. Unfortunately, these two professionals are not collaborating well enough, as patient outcomes, especially in relation to medication adherence, continue to decline. Coordinated care of patients can improve by expanding bidirectional communication and sharing additional patient information with each other. It will be necessary to continue to promote collaborative care in the educational and training stages of these professionals’ careers to build trust and understanding of professional scope. Ultimately, the healthcare infrastructure will have to continue to progress to make collaboration more available and valuable to physicians and pharmacists
