Frequency and temporal effects in linear optical quantum computing

Typically linear optical quantum computing (LOQC) models assume that all input photons are completely indistinguishable. In practice there will inevitably be nonidealities associated with the photons and the experimental setup which will introduce a degree of distinguishability between photons. We consider a nondeterministic optical controlled-NOT gate, a fundamental LOQC gate, and examine the effect of temporal and spectral distinguishability on its operation. We also consider the effect of utilizing nonideal photon counters, which have finite bandwidth and time response.

Extending the theory of Owicki and Gries with a logic of progress

This paper describes a logic of progress for concurrent programs. The logic is based on that of UNITY, molded to fit a sequential programming model. Integration of the two is achieved by using auxiliary variables in a systematic way that incorporates program counters into the program text. The rules for progress in UNITY are then modified to suit this new system. This modification is however subtle enough to allow the theory of Owicki and Gries to be used without change.

Treatment with metformin

Metformin is an anti-hyperglycaemic agent widely used in the treatment of type 2 diabetes. It counters insulin resistance through insulin-dependent and -independent effects on cellular nutrient and energy metabolism, improving glycaemic control without weight gain and without increasing the risk of hypoglycaemia. Metformin can also benefit several risk factors for vascular disease independently of glycaemic control. In subjects with metabolic syndrome, metformin improves prognosis. It decreases progression of impaired glucose tolerance to type 2 diabetes, assists weight reduction especially in conjunction with lifestyle management and exerts other potentially favourable cardiovascular effects. For example, metformin can modestly improve the lipid profile in some dyslipidaemic individuals, reduce pro-inflammatory cytokines and monocyte adhesion molecules and decrease advanced glycation end products. Metformin can also improve parameters of endothelial function in the macro- and micro-vasculature, indicating lower athero-thrombotic risk, but it does not appear to reduce blood pressure. In normoglycaemic individuals with risk factors for diabetes and in women with polycystic ovary syndrome there is evidence that metformin can defer or prevent the development of diabetes. Thus, metformin offers beneficial effects to delay the onset and reverse or reduce the progression of many of the metabolic features and cardiovascular risk factors associated with metabolic syndrome.

Metformin

Metformin is the only biguanide antihyperglycemic agent used in the treatment of type 2 (non-insulin dependent) diabetes mellitus. It counters insulin resistance partly by increased insulin action (so-called insulin sensitizing effects) and partly via actions that are not directly insulin dependent. Metformin reduces hepatic glucose output by suppression of gluconeogenesis and glycogenolysis. In skeletal muscle, metformin increases insulin-mediated glucose uptake and glycogen storage. Other actions of metformin that contribute to its blood glucose-lowering effect are reduced fatty acid oxidation and increased glucose turnover, the latter occurring particularly in the splanchnic bed .... © 2007 Copyright © 2007 Elsevier Inc.

A visual critical ethnography of youth develoment in a Rio de Janeiro favela

Favelas are Brazilian informal housing settlements that are areas of concentrated poverty. In Rio de Janeiro, favelas are perceived as areas of heightened criminal activity and violence, and residents experience discrimination, and little access to quality education and employment opportunities. In this context, hundreds of non-formal educational arts and leisure programs work to build the self-esteem and identity of youth in Rio's favelas as a way of preventing the youth from negative local influences. The Morrinho organization, located in the Pereira da Silva favela in Rio, uses art as a way for the local male youth to communicate their lived reality. This study used a visual critical ethnographic methodology to describe the way in which the Morrinho participants interpret living in a favela. Seventeen semi-structured interviews with young men aged 15 to 29, the feature-length documentary film on the organization, 206 researcher produced documentary style photographs of the Morrinho artwork, and the researcher's field notes were analyzed. Truth claims, ways of seeing as communicated through words and actions, were induced through a cyclical process of reconstructive horizon analysis that incorporated the societal context and critical theory. The participants communicated their concerns about life in a favela; however, they did not describe their societal positions in terms of complete marginalization. They named multiple benefits of living in Pereira da Silva, discussed positive and negative experiences in school, and described ways they circumvented discrimination. Morrinho as an organization was described as an enthralling game and a social project that benefited dozens of local youth. Character development was a valuable result of participation at Morrinho. The Morrinho artwork communicates a nuanced vision of both benevolent and violent social actors, and counters the overwhelmingly negative dominant characterization of Rio de Janeiro's favelas. This study has implications for an inclusive critical pedagogy and the use of art as a means to facilitate a transformative education. Further research is recommended to explore terminology used to refer to favelas, and perceptions that favela residents have of their experiences in public education.

(Table 1, page 1376) Chemical analyses of manganese nodules and crusts from the Pacific Ocean

A compilation of chemical analyses of Pacific Ocean nodules using an x-ray fluorescence technique. The equipment used was a General Electric XRD-5 with a tungsten tube. Lithium fluoride was used as the diffraction element in assaying for all elements above calcium in the atomic table and EDDT was used in conjunction with a helium path for all elements with an atomic number less than calcium. Flow counters were used in conjunction with a pulse height analyzer to eliminate x-ray lines of different but integral orders in gathering count data. The stability of the equipment was found to be excellent by the author. The equipment was calibrated by the use of standard ores made from pure oxide forms of the elements in the nodules and carefully mixed in proportion to the amounts of these elements generally found in the manganese nodules. Chemically analyzed standards of the nodules themselves were also used. As a final check, a known amount of the element in question was added to selected samples of the nodules and careful counts were taken on these samples before and after the addition of the extra amount of the element. The method involved the determination and subsequent use of absorption and activation factors for the lines of the various elements. All the absorption and activation factors were carefully determined using the standard ores. The chemically analyzed samples of the nodules by these methods yielded an accuracy to at least three significant figures.

A window on relationships: reflecting critically on a current restorative justice theory

Inherent in the task of theorising is a responsibility for ongoing critical reflection of the ideas presented (Steele, 2010). To that end, this article responds to the invitation extended by McCold and Wachtel to examine the conceptual theory of restorative justice they first presented in 2003 and which continues to be promoted globally. One particular aspect of their theory, the Social Discipline Window, is examined. Drawing on a qualitative, critical case study conducted in schools in Ontario, Canada, the article illustrates: (a) how unexamined theory can be problematic and promote practice that counters the principles of restorative justice; and (b) how people's lives can be impacted by power dynamics inherent in the theory presented (Woolford, 2009). In response, a revised Relationship Window is presented along with examples of how it can affect practice that is more consistently aligned with the philosophical foundations of restorative justice.

Age and sedimentation rates of bottom sediments from the Baltic Sea

An automated system is described for collecting and processing information from radiometric devices used in determination of isotopic age and sedimentation rate by radiocarbon and lead-210 methods. The system is used in a day-and-night continuous measuring mode, with six radiocarbon liquid counters and two low-background beta-counters. Examples are given of use of the system to determine average sedimentation rates in the Baltic Sea.

From brown envelopes to community benefits: the co-option of planning gain agreements under deepening neoliberalism

The provision of physical and social infrastructure in the form of roads, green spaces and community facilities has traditionally been provided for by the state through the general taxation system. However, as the state has been transformed along more neoliberal lines, the private sector is increasingly relied upon to deliver public goods and services. Planning gain agreements have flourished within this context by offering another vehicle through which local facilities are privately funded. Whilst these agreements reflect the broader dynamics of neoliberalism, they are commonly viewed as a tool which can be employed to challenge these very dynamics by empowering local communities to secure more just planning outcomes. This paper counters such claims. Based on evidence gathered from 80 interviews with planners, councillors, developers and community groups in Ireland, the paper demonstrates how planning gain agreements have been strategically redeployed by the holders of political and economic power to serve their own ends. In seeking to understand why and how this has occurred, specific consideration is given to the changing power dynamics between the state and private capital under neoliberalism. The paper highlights how institutional arrangements have enabled developers to infiltrate the political sphere in more subtle and implicit ways than ever before. We conclude by arguing that planning gain must be understood as a mechanism which has been manipulated in ways which essentially work to preserve and enhance, rather than redress, existing power imbalances in the planning system by facilitating large scale transfers of wealth upwards in society.

On Multi- Server Queues With Consultation With Main Server

Queueing Theory is the mathematical study of queues or waiting lines. Queues abound in every day life - in computer networks, in tra c islands, in communication of electro-magnetic signals, in telephone exchange, in bank counters, in super market checkouts, in doctor's clinics, in petrol pumps, in o ces where paper works to be processed and many other places. Originated with the published work of A. K. Erlang in 1909 [16] on congestion in telephone tra c, Queueing Theory has grown tremendously in a century. Its wide range applications includes Operations Research, Computer Science, Telecommunications, Tra c Engineering, Reliability Theory, etc.
