description: We consider the application of logarithmic conformal field theory in finding solutions to the turbulent phases of 2-dimensional models of magnetohydrodynamics. These arise upon dimensional reduction of standard (infinite conductivity) 3-dimensional magnetohydrodynamics, after taking various simplifying limits. We show that solutions of the corresponding Hopf equations and higher order integrals of motion can be found within the solutions of ordinary turbulence proposed by Flohr, based on the tensor product of the logarithmic extension ${\tilde c}_{6,1} $ of the non-unitary minimal model $c_{6,1} $. This possibility arises because of the existence of a continuous hidden symmetry present in the latter models, and the fact that there appear several distinct dimension -1 and -2 primary fields.

description: We determine the zero-bias anomaly of the conductance of tunnel junctions by an approach unifying the conventional Coulomb blockade theory for ultrasmall junctions with the diffusive anomalies in disordered conductors. Both, electron-electron interactions within the electrodes and electron-hole interactions between the electrodes are taken into account nonperturbatively. Explicit results are given for one- and two-dimensional junctions, and the crossover to ultrasmall junctions is discussed.

description: A previous scaling analysis of pressure experiments in heavy fermion is reviewed and enlarged. We show that the critical exponents obtained from this analysis indicate that a one-parameter scaling describes these experiments. We obtain explicitly the enhancemente factors showing that these systems are indeed near criticality and that the scaling approach is appropriate. The physics responsible for the one-parameter scaling and breakdown of hyperscaling is clarified. We discuss a microsocopic theory that is in agreement with the experiments. The scaling theory is generalized for the case the shift and crossover exponents are different. The exponents governing the physical behavior along the non-Fermi liquid trajectory are obtained for this case.

The reduced phase space of spherically symmetric Einstein-Maxwell theory including a cosmological constant

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We extend here the canonical treatment of spherically symmetric (quantum) gravity to the most simple matter coupling, namely spherically symmetric Maxwell theory with or without a cosmological constant. The quantization is based on the reduced phase space which is coordinatized by the mass and the electric charge as well as their canonically conjugate momenta, whose geometrical interpretation is explored. The dimension of the reduced phase space depends on the topology chosen, quite similar to the case of pure (2+1) gravity. We investigate several conceptual and technical details that might be of interest for full (3+1) gravity. We use the new canonical variables introduced by Ashtekar, which simplifies the analysis tremendously.

description: In an induced-gravity model, the stability condition of an inflationary slow-rollover solution is shown to be $ϕ_0 \partial_{ϕ_0}V(ϕ_0)=4V(ϕ_0)$. The presence of higher derivative terms will, however, act against the stability of this expanding solution unless further constraints on the field parameters are imposed. We find that these models will acquire a non-vanishing cosmological constant at the end of inflation. Some models are analyzed for their implication to the early universe.

description: We demonstrate single and multi-shot Fourier transform holography with the use of a tabletop extreme ultraviolet laser. The reference wave was produced by a Fresnel zone plate with a central opening that allowed the incident beam to illuminate the sample directly. The high reference wave intensity allows for larger objects to be imaged compared to mask-based lensless Fourier transform holography techniques. We obtain a spatial resolution of 169 nm from a single laser pulse and a resolution of 128 nm from an accumulation of 20 laser pulses for an object ~11x11μm 2 in size. This experiment utilized a tabletop extreme ultraviolet laser that produces a highly coherent ~1.2 ns laser pulse at 46.9 nm wavelength.

description: We present the first search for binary companions of Massive Young Stellar Objects (MYSOs) using AO-assisted $K$ band observations, with NaCo at the VLT. We have surveyed 32 MYSOs from the RMS catalogue, probing the widest companions, with a physical separation range of 400 - 46,000 au, within the predictions of models and observations for multiplicity of MYSOs. Statistical methods are employed to discern whether these companions are physical rather than visual binaries. We find 18 physical companions around 10 target objects, amounting to a multiplicity fraction of 31$\pm$8\% and a companion fraction of 53$\pm$9\%. For similar separation and mass ratio ranges, MYSOs seem to have more companions than T Tauri or O stars, respectively. This suggests that multiplicity increases with mass and decreases with evolutionary stage. We compute very rough estimates for the mass ratios from the $K$ band magnitudes, and these appear to be generally larger than 0.5. This is inconsistent with randomly sampling the IMF, as predicted by the binary capture formation theory. Finally, we find that MYSOs with binaries do not show any different characteristics to the average MYSO in terms of luminosity, distance, outflow or disc presence.

description: Using the Carlip's method we have derived the boundary action for the fermion Chern-Simons theory of quantum Hall effects on a planar region with a boundary. We have computed both the bulk and edge responses of currents to the external electric field. From this we obtain the well-known anomaly relation and the boundary Hall current without introducing any ad hoc assumptions such as the chirality condition. In addition, the edge current on the common boundary of two samples is found to be proportional to the difference between Chern-Simons coupling strengths.

description: We calculate the dc Josephson current for two superconductor-ferromagnet (S/F) bilayers separated by a thin insulating film. It is demonstrated that the critical Josephson current $I_{c}$ in the junction strongly depends on the relative orientation of the effective exchange field $h$ of the bilayers. We found that in the case of an antiparallel orientation, $I_{c}$ increases at low temperatures with increasing $h$ and at zero temperature has a singularity when $h$ equals the superconducting gap $Δ$. This striking behavior contrasts suppression of the critical current by the magnetic moments aligned in parallel and is an interesting new effect of the interplay between superconductors and ferromagnets.

Generalized boundary conditions for general relativity for the asymptotically flat case in terms of Ashtekar's variables
Creators: name: Thiemann, T.
Publisher: name: arXiv
Year: 1999
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: There is a gap that has been left open since the formulation of general relativity in terms of Ashtekar's new variables namely the treatment of asymptotically flat field configurations that are general enough to be able to define the generators of the Lorentz subgroup of the asymptotical Poincaré group. While such a formulation already exists for the old geometrodynamical variables, up to now only the generators of the translation subgroup could be defined because the function spaces of the fields considered earlier are taken too special. The transcription of the framework from the ADM variables to Ashtekar's variables turns out not to be straightforward due to the a priori freedom to choose the internal SO(3) frame at spatial infinity and due to the fact that the non-trivial reality conditions of the Ashtekar framework reenter the stage when imposing suitable boundary conditions on the fields and the Lagrange multipliers.

We find exact agreement with the coefficient appearing in the Randall-Sundrum brane-world proposal. This provides more evidence for the complementarity of the two pictures.

description: KIC 08626021 is a pulsating DB white dwarf of considerable recent interest, and first of its class to be extensively monitored by Kepler for its pulsation properties. Fitting the observed oscillation frequencies of KIC 08626021 to a model can yield insights into its otherwise-hidden internal structure. Template-based white dwarf models choose a luminosity profile where the luminosity is proportional to the enclosed mass, $L_r \propto M_r$, independent of the effective temperature $T_{\rm eff}$. Evolutionary models of young white dwarfs with $T_{\rm eff} \gtrsim$ 25,000 K suggest neutrino emission gives rise to luminosity profiles with $L_r$ $\not\propto$ $M_r$. We explore this contrast by comparing the oscillation frequencies between two nearly identical white dwarf models: one with an enforced $L_r \propto M_r$ luminosity profile and the other with a luminosity profile determined by the star's previous evolution history. We find the low order g-mode frequencies differ by up to $\simeq$ 70 $μ$Hz over the range of Kepler observations for KIC 08626021. This suggests that by neglecting the proper thermal structure of the star (e.g., accounting for the effect of plasmon neutrino losses), the model frequencies calculated by using an $L_r \propto M_r$ profile may have uncorrected, effectively-random errors at the level of tens of $μ$Hz. A mean frequency difference of 30 $μ$Hz, based on linearly extrapolating published results, suggests a template model uncertainty in the fit precision of $\simeq$ 12% in white dwarf mass, $\simeq$ 9% in the radius, and $\simeq$ 3% in the central oxygen mass fraction.

description: Random input patterns induce a partition of the coupling space of a perceptron into cells labeled by their output sequences. Learning some data with a maximal error rate leads to clusters of neighboring cells. By analyzing the internal structure of these clusters with the formalism of multifractals, we can handle different storage and generalization tasks for lazy students and absent-minded teachers within one unified approach. The results also allow some conclusions on the spatial distribution of cells.

Three worlds of marriage effects? Gendered marriage earning differences in the United States, Germany, and Sweden
Creators: name: Geist, Claudia
Publisher: name: JFR - Journal of Family Research
Year: 2017

description: Being married is associated with many advantages. However, we do not know enough about the actual impact of entering marriage on individuals’ earnings, especially for women. In this paper, I examine the immediate and the short-term impact of marriage on men’s and women’s earnings in the United States, Germany, and Sweden. Studying the impact of marriage on earnings in three distinct socio-political settings provides insights into the context dependency of the link between marriage and earnings. Fixed effects models show that marriage transitions are not associated with women’s earnings in the United States and Sweden. For German women, I find an earnings penalty for marriage. Once I adjust for selection into employment, I find that employed German women with low employment propensities may experience instantaneous earnings boosts when they enter marriage, but that among women who are more firmly attached to the labor market, there is a short-term marriage penalty. For men in all three countries, I find no effect of marital transitions once employment likelihood is taken into account. Zusammenfassung Verheiratet zu sein wird mit vielen Vorteilen in Verbindung gebracht, aber wir wissen nicht genug über den tatsächlichen Effekt des Eheeintritts auf individuelles Einkommen, insbesondere für Frauen. In diesem Beitrag werden die unmittelbaren und kurzfristigen Effekte untersucht, die eine Verehelichung auf die Einkommen von Männern und Frauen in den USA, in Deutschland und in Schweden hat. Die Untersuchung des Einkommenseffekts der Ehe in drei unterschiedlichen sozial-politischen Settings ermöglicht Einsichten in die Kontextabhängigkeit des Zusammenhangs zwischen Heirat und Einkommen. Mit Fixed-Effects-Modellen wird aufgezeigt, dass der Übergang zur Ehe weder in den Vereinigten Staaten noch in Schweden mit dem Einkommen von Frauen zusammenhängt, während deutsche Frauen dadurch Einkommenseinbußen hinnehmen müssen. Kontrolliert man jedoch die Selektionseffekte bei der Aufnahme einer Beschäftigung, so kommt man zu dem Ergebnis, dass erwerbstätige Frauen in Deutschland mit niedriger Beschäftigungsneigung bei Ehe-Eintritt umgehend Einkommenszuwächse erfahren, dass aber Frauen, die stärker in den Arbeitsmarkt eingebunden sind, dann kurzfristig negativ sanktioniert werden. Für die Männer in den drei Ländern kommt es jedoch beim Übergang in die Ehe zu keinen Einkommenseffekten, wenn deren Beschäftigungswahrscheinlichkeit berücksichtigt wird.

The development, educational stratification and decomposition of mothers’ and fathers’ childcare time in Germany. An update for 2001-2013
Creators: name: Schulz, Florian

Publisher: name: JFR - Journal of Family Research

description: This study updates empirical knowledge about the development,(the educational stratification, and the decomposition of mothers’ and fathers’ childcare time in Germany with the most recent time use data. Using time series data from the German Time Use Study 2001/2002 and 2012/ 2013, we analyze time budgets for total childcare and six specific childcare activities on weekdays and weekends and estimate OLS regressions and Oaxaca decompositions. The study found that total childcare time has increased for mothers and fathers between 2001 and 2013 and that this change is predominantly due to increased time for basic childcare. It also found consistent evidence of an education gradient only for reading time with children. If there is significant change of time budgets between 2001 and 2013, this change seems to be driven by behavioral change rather than changing demographics. Our empirical findings on childcare time in Germany do not provide evidence of dynamics and stratification but rather of stability and similarity across parents’ educational levels. Besides the updates on German parents’ development, stratification and decomposition of time use for childcare, these analyses show that change in total childcare is not due to a proportional change over all single activities but due to changes in a few activities only. Zusammenfassung Diese Studie aktualisiert das empirische Wissen über die Entwicklung, die Bildungsstratifizierung und die Dekomposition der Zeitverwendung von Müttern und Vätern für Kinderbetreuung mit den aktuellen Zeitbudgetdaten für Deutschland. Auf Basis der der letzten beiden Erhebungen der Deutschen Zeitverwendungsstudie 2001/2002 und 2012/2013 werden die Zeitbudgets für die Gesamtzeit für Kinderbetreuung sowie sechs Einzeltätigkeiten mit OLS-Regressionen und Oaxaca- Dekompositionen untersucht. Die Studie zeigt, dass die Zeit für Kinderbetreuung von Müttern und Vätern zwischen 2001 und 2013 angestiegen ist, es einen Bildungsgradienten für Vorlesen gibt und signifikante Veränderungen in den Zeitbudgets nicht auf Kompositionsveränderung der Bevölkerung zurückgeführt werden können. Insgesamt belegt die Studie weniger die Dynamik als vielmehr die Stabilität und die geringe Bildungsdifferenzierung der Zeitverwendung für Kinderbetreuung. Darüber hinaus wird gezeigt, dass die Veränderungen in der Gesamtzeit für Kinderbetreuung nicht auf proportionale Veränderungen in allen, sondern nur auf Veränderungen in wenigen Einzeltätigkeiten zurückgeführt werden können.

description: Femtosecond spectroscopy is an important tool for tracking rapid photoinduced processes in a variety of materials. To spatially map the processes in a sample would substantially expand the capabilities of the method. This is, however, difficult to achieve due to the necessity to use low-noise detection and to maintain feasible data acquisition time. Here we demonstrate realization of an imaging pump-probe setup, featuring sub-100 fs temporal resolution, by a straightforward modification of a standard pump-probe technique, using a randomly structured probe beam. The structured beam, made by a diffuser, enabled us to computationally reconstruct the maps of transient absorption dynamics based on the concept of compressed sensing. We demonstrate the functionality of the setup in two proof-of-principle experiments, were we achieve spatial resolution of 20 μm. The presented concept provides a feasible route to imaging, using the pump-probe technique and ultrafast spectroscopy in general.

description: The effect of religiosity on a) the likelihood to have children, and b) the number of children is analyzed for East- and West-Germany using the Allgemeine Bevölkerungsumfrage der Sozialwissenschaften 2012 data and poisson-logit hurdle models. Religiosity is measured with Huber and Huber’s multidimensional concept of centrality. At first, the effect of religiosity on the likelihood to have children and the number of children is analyzed for East and West Germany – showing that religiosity influences fertility only in West Germany. Finally, mediator variables such as value of children, fertility norms, opinion on birth control, traditional gender roles as well as marriage patterns are used to explain why centrality increases fertility in West Germany. The analyses show that religious persons are more likely to have children, in particular because they more often marry. Although the mediator variables show the expected correlations with religiosity and family size, the mediators hardly explain the greater number of children in religious people. Zusammenfassung Anhand der Daten der Allgemeinen Bevölkerungsumfrage der Sozialwissenschaften von 2012 wird für Ost- und Westdeutschland der Einfluss christlicher Religiosität auf a) die Wahrscheinlichkeit der Elternschaft und b) die Anzahl der Kinder mithilfe von Poisson-Logit-Hurdle-Modellen untersucht. Religiosität wird hierbei anhand des mehrdimensionalen Konzepts der Zentralität nach Huber gemessen. Zunächst wird geprüft, ob Religiosität einen Effekt auf Elternschaft und die realisierte Kinderzahl hat, was nur in Westdeutschland der Fall ist. Schließlich wird untersucht, über welche Mechanismen die vorgefundenen Effekte vermittelt werden, wobei als Mediatoren Kindernutzen, Fertilitätsnormen, Bewertung von Geburtenkontrolle, Geschlechterrollen sowie Eheaffinität berücksichtigt werden. Die Mediationsanalysen für Westdeutschland deuten darauf hin, dass religiöse Personen vor allem aufgrund ihrer stärkeren Präferenz für die Ehe häufiger den Übergang zur Elternschaft vollziehen. Obwohl die Mediatoren die erwarteten Zusammenhänge mit Religiosität und Familiengröße aufweisen, kann die höhere Kinderzahl religiöser Personen kaum mit den verwendeten Mediatoren erklärt werden.

Motive für das zweite Kind. Eine qualitative Sekundäranalyse problemzentrierter Interviews
Creators: name: Holubek, Stefan
Publisher: name: JFR - Journal of Family Research
Year: 2017

description: The two-child family is a widespread ideal. It is, however, not a matter of course. Based on Miller’s Traits-Desires-Intentions-Behavior model, this paper investigates the motives of people for desiring a second child and how these motives may influence the progression towards intending this first family extension. The study uses secondary analyses of problem-centered interviews that are based on grounded theory methodology. As a result, four types of motives are identified. The second child may be interpreted as (a) a necessary component of the traditional family setting, as (b) a matter of course, (c) as a first sibling, and as (d) a “doubled” first child. Each of these motives has been scrutinized with regard to the specific circumstances causing people to intend having a second child. It is shown that identifying the respective motives for having a second child leads to a better understanding of the circumstances upon which particular actors start planning to actually have a second child. Zusammenfassung Zwei Kinder zu haben ist ein weit verbreitetes Ideal, aber keine Selbstverständlichkeit. Ziel dieses Beitrages ist es, orientiert am „Traits-Desires- Intention-Behaviour“-Modell nach Miller, Motive für den Wunsch nach einem zweiten Kind und ihre Rolle für den Übergang zur Intention zu untersuchen. Dafür werden problemzentrierte Interviews auf Grundlage der Grounded-Theory-Methodologie sekundär ausgewertet. Als Ergebnis werden vier Motive vorgestellt. Zweite Kinder werden als Teil eines traditionalen Familienbildes, als dispositionelle Selbstverständlichkeit, als „erstes Geschwisterkind“ und als „wiederholtes“ erstes Kind gedeutet. Die Motivlagen werden jeweils danach befragt, welche Informationen über Voraussetzungen für den Übergang in die Planungsphase sie enthalten. Dabei wird gezeigt, dass das Wissen über die Motivlagen dabei hilft, zu konkretisieren, unter welchen Bedingungen bestimmte Akteure dazu übergehen, das zweite Kind zu planen.

Ist Rechtsextremismus „erblich“? Zur Ähnlichkeit rechtsextremer Verhaltenstendenzen von Studierenden und ihren Eltern

description: The paper poses the question under which circumstances right-wing extremist behavioral tendencies of university students and their parents are likely to be similar. To answer this research question, 147 students, their mothers, and their fathers were surveyed. Unlike in most social research, the focus is on self-reported right-wing extremist everyday behavior (e.g., usage of derogatory language when talking about migrants), not attitudes. The hypothesis is tested that high intergenerational similarity in right-wing extremism requires the frame of a parental ideology that fosters such an orientation: the basis for intergenerational similarity is provided only in those families that have a high level of hierarchic self-interest (HSI, Hagan). In line with findings of socialization research on right-wing extremism, differences in similarities between mothers and fathers, on the one hand, and sons and daughters, on the other hand, are also assumed: Transmission effects should be particularly strong in the fatherson dyad. Both hypotheses are confirmed by the study. The paper concludes with the suggestion that prevention work in the field of right-wing extremism should include family workshops, including, in particular, fathers and sons. Zusammenfassung Der Beitrag untersucht, unter welchen Bedingungen sich alltägliche rechtsextreme Verhaltenstendenzen von Studierenden und ihren Eltern ähneln. Hierzu wurden 147 Studierende, ihre Mütter und ihre Väter befragt. Anders als in vielen sozialwissenschaftlichen Studien geht es um selbstberichtetes rechtsextremes Alltagsverhalten (etwa die Nutzung herabwürdigender Sprache zur Bezeichnung von Migranten), nicht um Einstellungen. Die These wird geprüft, dass hohe intergenerationale Ähnlichkeit eine dem Rechtsextremismus förderliche ideologische Orientierung der Eltern als Frame voraussetzt: Nur in Familien mit einem hohen Level an Hierarchischem Selbstinteresse (HSI, Hagan) ist der Boden für intergenerationale Ähnlichkeit gelegt. Unterschiede in der Ähnlichkeit zwischen Müttern und Vätern bzw. Söhnen und Töchtern werden – im Einklang mit Befunden der Sozialisationsforschung zum Rechtsextremismus – ebenfalls angenommen: Transmissionseffekte in der Vater-Sohn-Dyade sollten besonders deutlich ausfallen. Beide Thesen werden bestätigt. Der Beitrag schließt mit dem Vorschlag, in die Prävention von Rechtsextremismus auch Elternarbeit, insbesondere die Arbeit mit Vätern und Söhnen einzubeziehen.

Doping optimization for the power factor of bipolar thermoelectric materials

description: Bipolar carrier transport is often a limiting factor in the thermoelectric efficiency of narrow bandgap materials at high temperatures due to the reduction in the Seebeck coefficient and the introduction of an additional term to the thermal conductivity. Using the Boltzmann transport formalism and a two-band model, we simulate transport through bipolar systems and calculate their thermoelectric transport properties: the electrical conductivity, the Seebeck coefficient and the thermoelectric power factor. We present an investigation into the doping optimisation of such materials, showing the detrimental impact that rising temperatures have if the doping (and the Fermi level) is not optimised for each operating temperature. We also show that the doping levels for optimized power factors at a given operating temperature differ in bipolar systems compared to unipolar ones. We show finally that at 600 K, in a bipolar material with bandgap approximately that of Bi2Te3, the optimal doping required can reside between 10% - 30% larger than that required for an optimal unipolar material depending on the electronic scattering details of the material.

Charge Stripes and Antiferromagnetism in Insulating Nickelates and Superconducting Cuprates

description: Neutron and X-ray scattering studies have provided strong evidence for coupled spatial modulations of charge and spin densities in layered nickelates and cuprates. The accumulated results for La(2-x)Sr(x)NiO(4+d) are consistent with the strongly-modulated topological-stripe concept. Clues from Nd-doped La(2-x)Sr(x)CuO(4) suggest similar behavior for the cuprates. The experimental results are summarized, and features that conflict with an interpretation based on a Fermi-surface instability are emphasized. A rationalization for the differences in transport properties between the cuprates and nickelates is given.

Complete quantization of a diffeomorphism invariant field theory
Creators: name: Thiemann, T.
Publisher: name: arXiv
Year: 1999
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In order to test the canonical quantization programme for general relativity we introduce a reduced model for a real sector of complexified Ashtekar gravity which captures important properties of the full theory. While it does not correspond to a subset of Einstein's gravity it has the advantage that the programme of canonical quantization can be carried out completely and explicitly, both, via the reduced phase space approach or along the lines of the algebraic quantization programme. This model stands in close correspondence to the frequently treated cylindrically symmetric waves. In contrast to other models that have been looked at up to now in terms of the new variables the reduced phase space is infinite dimensional while the scalar constraint is genuinely bilinear in the momenta. The infinite number of Dirac observables can be expressed in compact and explicit form in terms of the original phase space variables. They turn out, as expected, to be non-local and form naturally a set of countable cardinality.

Resolution of causal paradoxes arising from opposing thermodynamic arrows of time

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: It was recently shown \cite{opposite} that systems with opposite thermodynamic arrows of time could have moderate mutual interaction with neither destroying the order of the other. Such interaction includes signaling. Signals, however, may give rise to causal paradoxes, suggesting that "moderate" interaction may be impossible. Using the two-time boundary condition framework, we resolve the paradoxes. In one example, at a macroscopic level, we establish the existence of solutions to the appropriate boundary value problem. This result is extended to a class of microscopic problems. We also produce an example in which microscopic data are given and there is no solution. This is a different kind of resolution: there is no paradox because the events do not happen. Finally we discuss the differences between these cases.

Multiple Risk Factor Control in Individuals with Type 2 Diabetes and Microalbuminuria

description: The overall aim of this PhD was to evaluate the long-term clinical, and cost-effectiveness of multiple risk factor control defined as intensive control of blood glucose, blood pressure and lipid levels, either singularly or in combination as a multifactorial intervention in individuals with type 2 diabetes and microalbuminuria, when compared to standard care.The results from systematic review and meta-analysis suggested that interventions for risk factors control favour the trends towards a reduction in the risk of myocardial infarction (MI) [risk ratio (RR) 0.50; 95% confidence interval (CI) 0.20,1.22; P=0.127], stroke (RR 0.44; 95% CI 0.10,1.91; P=0.275), CV-mortality (RR 0.95; 95% CI 0.48,1.86; P=0.874) or all-cause mortality (RR 0.80; 95% CI 0.51,1.25; P=0.324). Whereas the cohort analysis of real-world data from the United Kingdom (UK) primary care provided evidence that being at blood glucose, blood pressure, and cholesterol targets was associated with an overall 47%, 25%, 42%, 55% and 42% reduction in the risk of MI, stroke, renal disease, CV-mortality, and all-cause-mortality, respectively. The findings of the economic evaluation indicated that achieving multiple risk factor control in individuals with type 2 diabetes were not cost-effective [incremental cost-effectiveness ratio (ICER) per quality-adjusted life-year (QALY) gained was £39,750, with the probability of being cost-effective was 0.3375] in a UK setting; however, in the subgroup of individuals with type 2 diabetes and microalbuminuria, achieving multiple risk factor control were potentially cost-effective [ICER per QALY gained was £1,366, with the probability of being cost-effective was 0.5100].This thesis has assessed the long-term clinical, and cost-effectiveness of multiple risk factor control, through evidence synthesis methodologies, retrospective cohort analysis, and economic evaluation in people with type 2 diabetes and the subgroup of individuals with type 2 diabetes and microalbuminuria. However, uncertainty still surrounds the cost-effectiveness of multiple risk factor control, and further research is required.

description: We perform constant pressure Monte Carlo simulations of a spin-analogous model which describes coupled spatial and magnetic degrees of freedom on an fcc lattice. Our calculations qualitatively reproduce magnetovolume effects observed in some rare earth manganese compounds, especially in the anti-Invar material YMn2. These are a sudden collapse of the magnetic moment which is connected with a huge volume change, and a largely enhanced thermal expansion coefficient.
