Shear viscosity in magnetized neutron star crust

The electron shear viscosity due to Coulomb scattering of degenerate electrons by atomic nuclei throughout a magnetized neutron star crust is calculated. The theory is based on the shear viscosity coefficient calculated neglecting magnetic fields but taking into account gaseous, liquid and solid states of atomic nuclei, multiphonon scattering processes, and finite sizes of the nuclei albeit neglecting the effects of electron band structure. The effects of strong magnetic fields are included in the relaxation time approximation with the effective electron relaxation time taken from the field-free theory. The viscosity in a magnetized matter is described by five shear viscosity coefficients. They are calculated and their dependence on the magnetic field and other parameters of dense matter is analyzed. Possible applications and open problems are outlined.Comment: 6 pages, 3 figures, EPL, accepte

Developments in space power components for power management and distribution

Advanced power electronic components development for space applications is discussed. The components described include transformers, inductors, semiconductor devices such as transistors and diodes, remote power controllers, and transmission lines

Interrelationships between interstellar and interplanetary grains

The relationship between solar system dust (SSD) and interstellar dust particles (ISMD) is being reconsidered because of the discovery of isotopic anomalies in meteorites. Meteoritic, circumstellar/meteoritic, interstellar/meteoritic, planetary, and cometary data are reviewed

A qualitative investigation of elite golf coaches' knowledge and the epistemological chain

The aim of the study was to explore the existence and application of the epistemological chain (EC) construct in the decision making of elite golf coaches. Eight male expert golf coaches were recruited for the study. Employing a qualitative methodology, semi-structured interviews were conducted to gain understanding of the participants‟ perceptions and application of the EC and to determine its overall effect on their knowledge development. Data were analysed to identify themes using interpretive phenomenological analysis (IPA). Results indicate the EC is indeed present in the coaching of elite golfers and implemented in a structured and coherent form. This raises a number of interesting issues regarding coach and player development that may impact upon future pedagogical provision

The Coronavirus: Biopolitics and the Rise of ‘Anthropocene Authoritarianism’

If the lesson of the global response to the Coronavirus is that humanity itself is the problem, then Anthropocene Authoritarianism looks set to pose a larger long-term challenge to our ways of life than the virus itself. With politics suspended, societies under lockdown, parliaments closed and States of Emergency in force globally (Runciman, 2020), many commentators have turned to Foucauldian-inspired understandings of biopolitics and population control to analyze contemporary events (Horvat, 2020; Agamben, 2020a; Demetri, 2020; Singh, 2020; Sotiris, 2020). Biopolitics has become a key concept in critical discourses of security governance in the last two decades (Rose, 2007; Esposito, 2008; Dillon, 2015). Deriving from the work of Foucault, at the heart of biopolitical thought is the relationship of politics to life as both the basis of governance and as an object to be secured (Foucault, 2007; 2008). For Foucault, ‘life’ was a way of articulating an ‘outside’ to the human world of politics, an outside that appeared natural but was, in fact, a malleable construct (Lemke, 2011)

Ethical issues of electronic patient data and informatics in clinical trial settings

The field of cancer bio-informatics unites the disciplines of scientific and clinical research withclinical practice and the treatment of individual patients. There is a need to study patients andsometimes their families, over many decades, to follow disease progress and long-term outcomes.This may require research teams to access the routinely-collected health data from generalpractice and hospital health records, prior to and after the cancer diagnosis is made. This clinicalinformation will increasingly include data provided by patients or acquired from them throughwearable devices that can monitor or deliver treatment, and data acquired from genetic relativesof the patient.All of these data, whether explicitly collected for the purpose of a clinical study, or routinelycollected as part of a patient?s life-time healthcare journey, are personal health data. There areethical and legal requirements to manage these data with care. This chapter explores the ethicalrequirements for collecting, holding, analysing and sharing personal health data, and thelegislation covering such activities

Long-range correlations and ensemble inequivalence in a generalized ABC model

A generalization of the ABC model, a one-dimensional model of a driven system of three particle species with local dynamics, is introduced, in which the model evolves under either (i) density-conserving or (ii) nonconserving dynamics. For equal average densities of the three species, both dynamical models are demonstrated to exhibit detailed balance with respect to a Hamiltonian with long-range interactions. The model is found to exhibit two distinct phase diagrams, corresponding to the canonical (density-conserving) and grand canonical (density nonconserving) ensembles, as expected in long-range interacting systems. The implication of this result to nonequilibrium steady states, such as those of the ABC model with unequal average densities, are briefly discussed.Comment: 4 pages, 2 figures. v2: minor changes with an added reference, published versio
