The solid solution Gd2NixCu2-xMg: Large reversible magnetocaloric effect and a drastic change of the magnetism by substitution

Various samples of the solid solution Gd2NixCu2-xMg were synthesized from the elements in sealed tantalum ampoules in an induction furnace. All members crystallize with the tetragonal Mo2FeB2 type structure, space group P4/mbm, and they were characterized on the basis of Guinier powder patterns and energy dispersive X-rays analyses. The lattice parameters decrease with increasing nickel content in

Circadian variation in dominant atrial fibrillation frequency in persistent atrial fibrillation

Circadian variation in atrial fibrillation (AF) frequency is explored in this paper by employing recent advances in signal processing. Once the AF frequency has been estimated and tracked by a hidden Markov model approach, the resulting trend is analyzed for the purpose of detecting and characterizing the presence of circadian variation. With cosinor analysis, the results show that the short-term

Redox Chemistry in Two Iron-Bentonite Field Experiments at Äspö Hard Rock Laboratory, Sweden: An XRD and Fe K-Edge XANES Study

Excavated bentonite from two large iron-bentonite field experiments at Aspo Hard Rock Laboratory in Sweden was investigated with respect to iron redox chemistry and mineralogy. The iron redox chemistry was studied by Fe K-edge X-ray absorption near edge structure spectroscopy and the mineral phases were studied using X-ray diffraction. Bentonite is to be used as a buffer material in high-level rad

A Remarkably Complex Supramolecular Hydrogen-Bonded Decameric Capsule Formed from an Enantiopure C2-Symmetric Monomer by Solvent-Responsive Aggregation.

The formation of an unprecedented decameric capsule in carbon disulfide, held together by the combination of double and triple hydrogen bonds between isocytosine units embedded in an enantiomerically pure bicyclic framework is reported. The aggregation occurs via symmetry breaking of the enantiopure intrinsically C2-symmetric monomer brought about by solvent, induced tautomerization of the hydroge

Activity-based accounts of mechanism and the threat of polygenic effects

Accounts of ontic explanation have often been devised so as to provide an understanding of mechanism and of causation. Ontic accounts differ quite radically in their ontologies, and one of the latest additions to this tradition proposed by Peter Machamer, Lindley Darden and Carl Craver reintroduces the concept of activity. In this paper I ask whether this influential and activity-based account of

The APC-PCI concentration as an early marker of activation of blood coagulation A study of women on combined oral contraceptives

Background: The risk of venous tromboembolism (VTE) in women taking combined oral contraceptives (COCs) is attributed to changes in coagulation and fibrinolysis. The impact of the COCs may be greater in women with preexisting thrombophilic defects. Nevertheless most women who suffer from venous thrombosis do not have any of the well known hereditary or acquired risk factors. A simple and sensitive

A Fast Crank Angle Resolved Zero-Dimensional NOx Model Implemented on a Field-Programmable Gate Array

In the automotive industry, the piezo-based in-cylinder pressure sensor is getting commercialized and used in production vehicles. For example, the pressure sensor offers the opportunity to design algorithms for estimation of engine emissions, such as soot and NO, during a combustion cycle. In this paper a zero-dimensional NO model for a diesel engine is implemented that will be used in real time.

Genetic determinants of heel bone properties: genome-wide association meta-analysis and replication in the GEFOS/GENOMOS consortium

Quantitative ultrasound of the heel captures heel bone properties that independently predict fracture risk and, with bone mineral density (BMD) assessed by X-ray (DXA), may be convenient alternatives for evaluating osteoporosis and fracture risk. We performed a meta-analysis of genome-wide association (GWA) studies to assess the genetic determinants of heel broadband ultrasound attenuation (BUA; n

Picking personalities apart: estimating the influence of predation, sex and body size on boldness in the guppy Poecilia reticulata

Predation is a strong selective force in most natural systems, potentially fueling evolutionary changes in prey morphology, life history and behaviour. Recent work has suggested that contrasting predation pressures may lead to population differentiation in personality traits. However, there are indications that these personality traits also differ between sexes and not necessarily in a consistent

Leukocyte Complexity Predicts Breast Cancer Survival and Functionally Regulates Response to Chemotherapy

Immune-regulated pathways influence multiple aspects of cancer development. In this article we demonstrate that both macrophage abundance and T-cell abundance in breast cancer represent prognostic indicators for recurrence-free and overall survival. We provide evidence that response to chemotherapy is in part regulated by these leukocytes; cytotoxic therapies induce mammary epithelial cells to pro

Decision-Making Styles and Stress

This study analyzed the relationship between each of five decision-making styles, including Rational, Intuitive, Dependent, Avoidant, and Spontaneous (Scott & Bruce, 1995) and two indicators of stress, Perceived stress and Sleep quality, among administrative officers and investigators at three Swedish public authorities: The National Tax board, the Social Insurance agency, and the Police autho

Is the general factor of personality based on evaluative responding? Experimental manipulation of item-popularity in personality inventories.

The general factor of personality (GFP) is understood as a hierarchically superordinate factor, which suggests that it and the subordinate personality traits are mutually dependent on one another. If a personality inventory captures the subordinate traits the GFP should appear too. Likewise, manipulating the GFP should affect the subordinate traits and vice versa. The current study was an attempt

Physical Forces Regulate Plant Development and Morphogenesis.

Plant cells in tissues experience mechanical stress not only as a result of high turgor, but also through interaction with their neighbors. Cells can expand at different rates and in different directions from neighbors with which they share a cell wall. This in connection with specific tissue shapes and properties of the cell wall material can lead to intricate stress patterns throughout the tissu

Climate Barbarians at the Gate? A critique of apocalyptic narratives on 'climate refugees'

Climate-induced migration, and particularly the issue of climate refugees, is subject to growing attention in global climate governance. The debate on the topic sees the convergence of conflicting discourses (ranging from those of conservative European governments to southern NGOs) onto apocalyptic narratives that forecast massive, abrupt and unavoidable flows of climate refugees. Such dystopian n

Are the theoretical underpinnings and structure of the traditional monography conducive to the postmodern thesis?

In this article we argue that there are several similarities between the process of Bildung and the process of producing a modern monography which are mirrored in the final product of the thesis both in terms of content andstructure. A short historical summary of Bildung and hermeneuticsis given, followed by a discussion concerning the positioning and conceptualization of the individual within the

Coffee, tea and decaffeinated coffee in relation to hepatocellular carcinoma in a European population: Multicentre, prospective cohort study

Inverse associations of coffee and/or tea in relation to hepatocellular carcinoma (HCC) risk have been consistently identified in studies conducted mostly in Asia where consumption patterns of such beverages differ from Europe. In the European Prospective Investigation into Cancer and nutrition (EPIC), we identified 201 HCC cases among 486,799 men/women, after a median follow-up of 11 years. We ca

On observation distributions for state space models of population survey data.

1. State space models are starting to replace more simple time series models in analyses of temporal dynamics of populations that are not perfectly censused. By simultaneously modelling both the dynamics and the observations, consistent estimates of population dynamical parameters may be obtained. For many data sets, the distribution of observation errors is unknown and error models typically chos
