Non-equilibrium radiation nuclear reactor

An externally moderated thermal nuclear reactor is disclosed which is designed to provide output power in the form of electromagnetic radiation. The reactor is a gaseous fueled nuclear cavity reactor device which can operate over wide ranges of temperature and pressure, and which includes the capability of processing and recycling waste products such as long-lived transuranium actinides. The primary output of the device may be in the form of coherent radiation, so that the reactor may be utilized as a self-critical nuclear pumped laser

Entanglement in quantum catastrophes

We classify entanglement singularities for various two-mode bosonic systems in terms of catastrophe theory. Employing an abstract phase-space representation, we obtain exact results in limiting cases for the entropy in cusp, butterfly, and two-dimensional catastrophes. We furthermore use numerical results to extract the scaling of the entropy with the non-linearity parameter, and discuss the role of mixing entropies in more complex systems.Comment: 7 pages, 3 figure

Common mental disorders in people living with HIV/AIDS

The term ‘common mental disorders’ is an overarching term for conditions that affect a significant number of people in the community. These conditions include depression, anxiety and substance use disorders. In contrast, so-called ‘severe mental illnesses’ (such as schizophrenia or bipolar mood disorder) are conditions that usually require admission for inpatient treatment and tend both to recur and to be chronically debilitating. Nonetheless, common mental disorders result in a considerable burden to the individual, their families, the community and the economy. Many people with these conditions do not present for treatment, or if they do they usually present to primary care facilities, where these diagnoses are often missed. This is unfortunate, since there is good evidence that these disorders can be effectively treated1-2 and that much of this treatment can be provided by primary care clinicians.

Observation and inverse problems in coupled cell networks

A coupled cell network is a model for many situations such as food webs in ecosystems, cellular metabolism, economical networks... It consists in a directed graph $G$, each node (or cell) representing an agent of the network and each directed arrow representing which agent acts on which one. It yields a system of differential equations $\dot x(t)=f(x(t))$, where the component $i$ of $f$ depends only on the cells $x_j(t)$ for which the arrow $j\rightarrow i$ exists in $G$. In this paper, we investigate the observation problems in coupled cell networks: can one deduce the behaviour of the whole network (oscillations, stabilisation etc.) by observing only one of the cells? We show that the natural observation properties holds for almost all the interactions $f$

Advanced indium antimonide monolithic charge coupled infrared imaging arrays

The continued process development of SiO2 insulators for use in advanced InSb monolithic charge coupled infrared imaging arrays is described. Specific investigations into the use of plasma enhanced chemical vapor deposited (PECVD) SiO2 as a gate insulator for InSb charge coupled devices is discussed, as are investigations of other chemical vapor deposited SiO2 materials

Public health participation in alcohol licensing decisions in England: the importance of navigating "contested space"

The Police Reform and Social Responsibility Act of 2011, added ‘health bodies’ as responsible authorities in licensing and, in practice, Directors of Public Health undertook this role. Despite this legislation facilitating the inclusion of public health in partnerships around licensing in England, wide variations in involvement levels by Public Health professionals persist This article is based on the findings from interviews that explored the experiences of public health professionals engaging with local established partnerships around alcohol licensing. Qualitative data were collected through twenty-one interviews in a purposeful sample of London boroughs. These data were combined with analyses of relevant area documentation and observations of fourteen licensing sub-committee meetings in one London borough over a seven-month period. Thematic analysis of all data sources was conducted to identify emerging themes. This study highlighted the importance of successful navigation of the ‘contested space’ (Hunter and Perkins, 2014) surrounding both public health practice and licensing partnerships. In some instances, contested spaces were successfully negotiated and public health departments achieved an increased level of participation within the partnership. Ultimately, improvements in engagement levels of public health teams within licensing could be achieved. The paper explores a neglected aspect of research around partnership working and highlights the issues arising when a new partner attempts to enter an existing partnership

Binge drinking: a confused concept and its contemporary history

Binge drinking is a matter of current social, political and media concern. It has a long-term, but also a recent, history. This paper discusses the contemporary history of the concept of binge drinking. In recent years there have been significant changes in how binge drinking is defined and conceptualised. Going on a ‘binge’ used to mean an extended period (days) of heavy drinking, while now it generally refers to a single drinking session leading to intoxication. We argue that the definitional change is related to the shifts in the focus of alcohol policy and alcohol science, in particular in the last two decades, and also in the role of the dominant interest groups. The paper is a case study in the relationship between science and policy. We explore key themes, raise questions and point to a possible agenda for future research
