description: Staircase hysteresis loops of the magnetization of a LiY_0.998Ho_0.002F_4 single crystal are observed at subkelvin temperatures and low field sweep rates. This behavior results from quantum dynamics at avoided level crossings of the energy spectrum of single Ho^{3+} ions in the presence of hyperfine interactions. Enhanced quantum relaxation in constant transverse fields allows the study of the relative magnitude of tunnel splittings. At faster sweep rates, non-equilibrated spin-phonon and spin-spin transitions, mediated by weak dipolar interactions, lead to magnetization oscillations and additional steps.

„Involvierte“ Väter zwischen Beruf und Familie. Zur Re/Produktion von Männlichkeiten in paarinternen Aushandlungen

Year: 2017

description: Starting from the hypothesis discussed in research on masculinities and fathering that ‘involved’ fathering is incompatible with hegemonic masculinity, this paper examines continuity and change in interrelating work and family life by German fathers. Within the sociological frame of interaction theory on un/doing masculinity I focused on the production and presentation of gender differences and the hierarchizing demarcation against femininity and non-hegemonic masculinities within the couple. Based on 27 qualitative couples’ and individual interviews, three forms of re/production of masculinity were constructed and discussed along the dimensions of vocational/career concepts, financial care of the family, and parental leave arrangements within the couple. The results show that the re/production of masculinities within negotiations of the couples regarding paid and family work are fragile, challenged, or episodically undone. This implies that in addition to welfare state policies and work organizations, the negotiations within the couple about their division of paid and unpaid work have significant consequences for the un/equality between the parents. Zusammenfassung Ausgehend von der in der Männlichkeitsforschung diskutierten These, ‚involvierte‘ Väterlichkeit stehe im Widerspruch zum Leitbild erwerbszentrierter hegemonialer Männlichkeit, werden im vorliegenden Beitrag Kontinuitäten und Wandel in der Relationierung von Erwerbs- und Familienarbeit bei Vätern untersucht. Mit dem interaktionstheoretischen Ansatz zu ‚un/doing masculinity‘ liegt der Fokus auf der Her- und Darstellung von Geschlechterdifferenzen sowie der hierarchisierenden Abgrenzung zu Weiblichkeiten und nicht-hegemonialer Männlichkeiten im Paarkontext. Anhand von 27 qualitativen Paar- und Einzelinterviews werden – entlang der Dimensionen Berufs-/Karrierekonzept, finanzielle Versorgung der Familie und Elternzeitarrangement – drei Re/Produktionsformen erwerbszentrierter hegemonialer Männlichkeit rekonstruiert und diskutiert. Im Ergebnis zeigt sich, dass die Re/Produktion von Männlichkeiten in paarinternen Aushandlungen zu Erwerbs- und Familienarbeit fragil, herausgefordert oder episodisch ausgesetzt wird. Dies impliziert, dass auch die Aushandlungen auf der Paarebene zur Relationierung von Erwerbs- und Familienarbeit, neben wohlfahrtsstaatlichen Rahmungen und Arbeitsorganisationen, signifikante un/gleichheitsrelevante Folgen haben.

description: How deep do Saturn's zonal winds penetrate below the cloud-level has been a decades-long question, with important implications not only for the atmospheric dynamics, but also for the interior density structure, composition, magnetic field and core mass. The Cassini Grand Finale gravity experiment enables answering this question for the first time, with the premise that the planet's gravity harmonics are affected not only by the rigid body density structure but also by its flow field. Using a wide range of rigid body interior models and an adjoint based thermal wind balance, we calculate the optimal flow structure below the cloud-level and its depth. We find that with a wind profile, largely consistent with the observed winds, when extended to a depth of around 8,800 km, all the gravity harmonics measured by Cassini are explained. This solution is in agreement with considerations of angular momentum conservation, and is consistent with magnetohydrodynamics constraints.

description: The popularity of the ‘Elterngeld’ – the current parental allowance legislation in Germany – is considerably growing among fathers. By means of a multiple-method research approach, the influence of employment on paternity leave is investigated through the example of Bavaria – a federal state that has a particularly high rate of fathers taking parental leave. Contextual factors that might influence fathers’ involvement at the district level are investigated based on aggregated regional data using linear regression. It shows that a low rate of unemployment, job opportunities for highly qualified workers and an equitable balance in the participation of women and men in working life correlate with a higher rate of paternity leave. Individual rationales for taking parental leave are reconstructed on the basis of problem-focused interviews with Bavarian fathers and couples during paternity leave. The analysis revealed that, besides financial considerations, the emotional attachment to working life is of great importance for the decision of fathers taking parental leave. Even though the high income level in Bavaria is not – differently than previously assumed – crucial for the extensive use of ‘father months’, the findings confirm the overall importance of employment and the income level of both parents for the fathers’ decision on taking parental leave. Zusammenfassung Das Elterngeld erfreut sich bei Vätern zunehmender Beliebtheit. Am Beispiel Bayerns – einem Bundesland, in dem die Nutzung der ‚Vätermonate‘ besonders hoch ist und gleichzeitig regional variiert – wird mithilfe eines multimethodischen Designs untersucht, welche Bedeutung die Erwerbsarbeit für den Elterngeldbezug von Vätern hat. Auf der Grundlage aggregierter Regionaldaten wird zunächst mittels linearer Regression analysiert, welche Kontextfaktoren die Väterbeteiligung auf Kreisebene beeinflussen. Dabei zeigt sich, dass vor allem eine geringe Arbeitslosigkeit, das Arbeitsplatzangebot für hoch qualifizierte Beschäftigte und eine ausgewogene Erwerbsbeteiligung von Frauen und Männern mit einer höheren Väterbeteiligung am Elterngeld einhergehen. Zudem werden auf Grundlage problemzentrierter Interviews mit Vätern und Paaren individuelle Begründungen für den Elterngeldbezug des Vaters rekonstruiert. Neben finanziellen Erwägungen bestimmt eine emotionale Verwobenheit mit der Erwerbsarbeit die Elterngeld-Entscheidung. Insgesamt zeigt sich, wie bedeutsam die Erwerbsarbeit und das Einkommen beider Elternteile für die Elterngeldentscheidung sind, auch wenn das hohe bayerische Einkommensniveau nicht ausschlaggebend für die hohe Nutzung der Partnermonate ist.

title: Investigating the diversity, adaptations and potential roles of Blastocystis in the gut
Creators: name: Betts, Emma Louise
Publisher: name: University of Kent
Year: 2021

description: Blastocystis is ubiquitously distributed coloniser of the gastrointestinal tract. To date, 17 subtypes and other isolates have been characterised from a range of invertebrate and vertebrate hosts, including humans. Despite current knowledge regarding its prevalence, diversity and associations with the gut microbiota, there is still uncertainty about its role as a pathogen. Herein, I aimed to explore the diversity of Blastocystis and investigate its role(s) in the gut using a multiphasic approach, combining culturomics, with molecular biology, phylogenetics, metagenomics, transcriptomics, and metabolomics. This allowed for an investigation of not only the prevalence of Blastocystis, but aided in the exploration of its in vivo and in vitro function. Results from my thesis demonstrate that Blastocystis had a high incidence in asymptomatic captive animals, with an excess of 40% in the species sampled. Additionally, numerous novel hosts were identified, while showing that co-infection with other microbial eukaryotes was relatively frequent. Bacterial community profiling of Blastocystis positive animals demonstrated no overall changes to bacterial diversity, but highlighted a number of taxa that were associated with Blastocystis colonisation. In vitro and in vivo NMR metabolomics further revealed a distinct metabolome in positive individuals. Here, a number of metabolites linked to eubiosis were identified including l-arginine, l-glutamine and propanoate. Lastly, treatment of Blastocystis with oxygen revealed a number of pathways possibly implicated in oxygen stress responses. As a result, my Ph.D work provides a steppingstone to understand the prevalence of Blastocystis and the role of this questionable gut "parasite" in health and disease in both animals and humans.

description: Macroeconomic models currently used by policy makers generally assume that the workings of financial markets can be fully summarised by financial prices, because the Modigliani and Miller (1958) theorem holds. This paper argues that these models are too limited in describing how monetary policy (and other) shocks are transmitted to the economy and points to new directions. The models are too limited because they disregard an information asymmetry between borrowers and lenders and the importance of financial intermediaries not only for individual depositors but the economy as a whole. Incorporating financial market interactions into macroeconomic models will enhance the understanding of the transmission mechanisms of monetary policy and other shocks.

description: For a long time there were 3 main experimental indications in favor of the existence of sterile neutrinos: $\bar{ν_e}$ appearance in the $\bar{ν_μ}$ beam in the LSND experiment, $\bar{ν_e}$ flux deficit in comparison with theoretical expectations in reactor experiments, and $ν_e$ deficit in calibration runs with radioactive sources in the Ga solar neutrino experiments SAGE and GALEX. All three problems can be explained by the existence of sterile neutrinos with the mass square difference in the ballpark of $1~\mathrm{eV^2}$. Recently the MiniBooNE collaboration observed electron (anti)neutrino appearance in the muon (anti)neutrino beams. The significance of the effect reaches 6.0$σ$ level when combined with the LSND result. Even more recently the NEUTRINO-4 collaboration claimed the observation of $\bar{ν_e}$ oscillations to sterile neutrinos with a significance slightly higher than 3$σ$. If these results are confirmed, New Physics beyond the Standard Model would be required. More than 10 experiments are devoted to searches of sterile neutrinos. Six very short baseline reactor experiments are taking data just now. We review the present results and perspectives of these experiments.

description: The solutions of the Einstein-Maxwell-Chern-Simons theory are studied in (1+2) dimensions with the self-duality condition imposed on the Maxwell field. We give a closed form of the general solution which is determined by a single function having the physical meaning of the quasilocal angular momentum of the solution. This function completely determines the geometry of spacetime, also providing the direct computation of the conserved total mass and angular momentum of the configurations.

description: We begin this work calculating Halliwell's propagator in the case of a Mixmaster universe with small anisotropy. Afterwards in the context of the Decoherence Model we introduce in our system terms that comprise the self-measurement of the universe of this model by higher multipoles of matter. Analyzing self-measurement with the Restricted Path Integral Formalism we obtain Halliwell's modified propagator and find that a gauge invariant physical time emerges as consequence of this process. The conditions leading to Wheeler-DeWitt dynamics are also obtained. The comparison of our results with those of the isotropic case will enable us to conclude that the number of conditions to be satisfied in order to have Halliwell's regime is in the anisotropic situation bigger than in an isotropic universe. We obtain also in terms of the parameters of the measurement process an expression for the threshold in time beyond which the scale factors of this model are meaningless.

description: Double bars are thought to be important features for secular evolution in the central regions of galaxies. However, observational evidence about their origin and evolution is still scarce. We report on the discovery of the first Box-Peanut (B/P) structure in an inner bar detected in the face-on galaxy NGC 1291. We use the integral field data obtained from the MUSE spectrograph within the TIMER project. The B/P structure is detected as bi-symmetric minima of the $h_4$ moment of the line-of-sight velocity distribution along the major axis of the inner bar, as expected from numerical simulations. Our observations demonstrate that inner bars can follow a similar evolutionary path as outer bars, undergoing buckling instabilities. They also suggest that inner bars are long-lived structures, thus imposing tight constraints to their possible formation mechanisms

description: Alter(n)sgerechte Quartiersentwicklung unter Beachtung der Heterogenität des Alters Es ist sowohl ein politisches Ziel als auch der Wunsch älterer Menschen, möglichst lange selbstständig und selbstbestimmt im vertrauten Wohnumfeld leben zu können. Deshalb beschäftigen sich u.a. die Ökologische Gerontologie als auch multidisziplinäre Konzepte für die kommunale Praxis mit der Frage, wie gute Umwelten für das Altern bzw. alter(n)sgerechte Quartiere gestaltet sein sollten. In Anbetracht der zunehmenden Heterogenisierung des Alters kann es darauf keine einfachen Antworten geben. In Verknüpfung von öko- und sozialgerontologischen Perspektiven wird gefragt: Was kennzeichnet ein „alter(n)sgerechtes“ Quartier, welches der Heterogenität seiner älteren Bewohner*innen gerecht wird? Die vorliegende Studie ist eine Sekundäranalyse einer quantitativen Befragung der ab 60-Jährigen Bewohner*innen eines Gelsenkirchener Quartiers (n=424). Das Referenzquartier Schalke ist ein benachteiligtes Quartier im Ruhrgebiet und stellt damit eine besondere Herausforderung für die Entwicklung alter(n)sgerechter Umwelten dar. Insgesamt wird für neun Handlungsfelder von Quartiersentwicklung (Wohnen, Gemeinschaft/Nachbarschaft, Infrastruktur Alltag, Infrastruktur Gesundheit und Pflege, Mobilität, öffentlicher Raum, Partizipation/Engagement, Information/Kommunikation, Inklusion) nach sechs Differenzkategorien (Geschlecht, Mehrheitsbevölkerung/Minderheit, soziale Schicht/ Einkommen, Lebensphase/Alter, Haushaltsgröße/Familienstand, Gesundheit) analysiert, ob und worin Gemeinsamkeiten und Unterschiede in den Bedarfen und Interessen der Bewohner*innen an ein gutes Leben im Quartier bestehen. Im Ergebnis werden u.a. Handlungsempfehlungen für die kommunale Praxis präsentiert, welche mehrheitsrelevanten oder spezifischen Maßnahmen für bestimmte Subgruppen in welchen Handlungsfeldern angezeigt sind, um eine gute Person-Umwelt-Passung nicht nur für bestimmte „Gruppen“ Älterer herzustellen. Die Verknüpfung der ökogerontologischen Modelle mit den Praxiskonzepten alter(n)sgerechter Quartiersentwicklung und mit der Sozialen Gerontologie erweist sich als fruchtbar und reiht sich in andere aktuelle Ansätze ein, Altern wieder stärker im Raum zu kontextualisieren.

description: As the size of a Josephson junction is reduced, charging effects become important and the superconducting phase across the link turns into a periodic quantum variable. Isolated Josephson junction arrays are described in terms of such periodic quantum variables and thus exhibit pronounced quantum interference effects arising from paths with different winding numbers (Aharonov-Casher effects). These interference effects have strong implications for the excitation spectrum of the array which are relevant in applications of superconducting junction arrays for quantum computing. The interference effects are most pronounced in arrays composed of identical junctions and possessing geometric symmetries; they may be controlled by either external gate potentials or by adding/removing charge to/from the array. Here we consider a loop of N identical junctions encircling one half superconducting quantum of magnetic flux. In this system, the ground state is found to be non-degenerate if the total number of Cooper pairs on the array is divisible by N, and doubly degenerate otherwise (after the stray charges are compensated by the gate voltages).

description: The proton hyperfine shift K and NMR relaxation rate $1/T_1$ have been measured as a function of temperature in the S=1/2 Heisenberg antiferromagnetic ladder Cu2(C5H12N2)2Cl4. The presence of a spin gap $Δ\simeq J_\perp-J_\parallel$ in this strongly coupled ladder ($J_\parallel < J_\perp$) is supported by the K and $1/T_1$ results. By comparing $1/T_1$ at two different proton sites, we infer the evolution of the spectral functions $S_z(q,ω_n)$ and $S_\perp(q,ω_n)$. When the gap is significantly reduced by the magnetic field, two different channels of nuclear relaxation, specific to gapped antiferromagnets, are identified and are in agreement with theoretical predictions.

Initial Mass Function Variations Cannot Explain the Ionizing Spectrum of Low Metallicity Starbursts

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Observations of both galaxies in the distant Universe and local starbursts are showing increasing evidence for very hard ionizing spectra that stellar population synthesis models struggle to reproduce. Here we explore the effects of the assumed stellar initial mass function (IMF) on the ionizing photon output of young populations at wavelengths below key ionization energy thresholds. We use a custom set of binary population and spectral synthesis (BPASS) models to explore the effects of IMF assumptions as a function of metallicity, IMF slope, upper mass limit, IMF power law break mass and sampling. We find that while the flux capable of ionizing hydrogen is only weakly dependent on IMF parameters, the photon flux responsible for the He II and O VI lines is far more sensitive to assumptions. In our current models this flux arises primarily from helium and Wolf-Rayet stars which have partially or fully lost their hydrogen envelopes. The timescales for formation and evolution of both Wolf Rayet stars and helium dwarfs, and hence inferred population age, are affected by choice of model IMF. Even the most extreme IMFs cannot reproduce the He II ionizing flux observed in some high redshift galaxies, suggesting a source other than stellar photospheres. We caution that detailed interpretation of features in an individual galaxy spectrum is inevitably going to be subject to uncertainties in the IMF of its contributing starbursts. We remind the community that the initial mass function is fundamentally a statistical construct, and that stellar population synthesis models are most effective when considering entire galaxy populations rather than individual objects.

description: The self-dual random-bond eight-state Potts model is studied numerically through large-scale Monte Carlo simulations using the Swendsen-Wang cluster flipping algorithm. We compute bulk and surface order parameters and susceptibilities and deduce the corresponding critical exponents at the random fixed point using standard finite-size scaling techniques. The scaling laws are suitably satisfied. We find that a belonging of the model to the 2D Ising model universality class can be conclusively ruled out, and the dimensions of the relevant bulk and surface scaling fields are found to take the values $y_h=1.849$, $y_t=0.977$, $y_{h_s}=0.54$, to be compared to their Ising values: 15/8, 1, and 1/2.

description: Local, bulk response functions, e.g permittivity, and the macroscopic Maxwell equations completely specify the classical electromagnetic problem, which features only wavelength $λ$ and geometric scales. The above neglect of intrinsic electronic length scales $L_{\text{e}}$ leads to an eventual breakdown in the nanoscopic limit. Here, we present a general theoretical and experimental framework for treating nanoscale electromagnetic phenomena. The framework features surface-response functions---known as the Feibelman $d$-parameters---which reintroduce the missing electronic length scales. As a part of our framework, we establish an experimental procedure to measure these complex, dispersive surface response functions, enabled by quasi-normal-mode perturbation theory and observations of pronounced nonclassical effects---spectral shifts in excess of 30% and the breakdown of Kreibig-like broadening---in a quintessential multiscale architecture: film-coupled nanoresonators, with feature-sizes comparable to both $L_{\text{e}}$ and $λ$.

description: The evolution of the C-type low frequency quasi-periodic oscillations (LFQPOs) and associated time lag in transient black hole sources as a function of time can be explained by variation of the Compton cloud size in a Two Component Advective Flow solution (TCAF). A similar study of a persistent source, GRS~1915+105, has not been attempted. We fit the evolution of QPOs with propagatory oscillating shock (POS) solution for two sets of so-called $χ$-state observations and find that the shock steadily recedes with almost constant velocity when QPO frequency is decreasing and the spectrum is hardening. The shock moves inward with a constant velocity $v_0=473.0$ cm s$^{-1}$ and $v_0=400.0$ cm s$^{-1}$ respectively in these two cases, when the QPO frequency is increasing and the spectrum softens. This behavior is similar to what was observed in XTE~J1550-564 during the 1998 outburst. The time lag measured at the QPO frequency varies in a similar way as the size of the Compton cloud. Most interestingly, in both the cases, the lag switches sign (hard lag to soft lag) at a QPO frequency of $\sim 2.3 - 2.5$ Hz irrespective of the energy of photons. We find, at very low frequencies $< 1$ Hz, the Comptonizing Efficiency (CE) increases with QPO frequency and at higher QPO frequencies the trend is opposite. The time lags become mostly positive at all energies when CE is larger than $\sim 0.85\%$ for both the sources.

description: Distribution Asset Management is an important task performed by utility companies to prolong the lifetime of the critical distribution assets and to accordingly ensure grid reliability by preventing unplanned outages. This study focuses on microgrid applications for distribution asset management as a viable and less expensive alternative to traditional utility practices in this area. A microgrid is as an emerging distribution technology that encompasses a variety of distribution technologies including distributed generation, demand response, and energy storage. Moreover, the substation transformer, as the most critical component in a distribution grid, is selected as the component of the choice for asset management studies. The resulting model is a microgrid-based distribution transformer asset management model in which microgrid exchanged power with the utility grid is reshaped in such a way that the distribution transformer lifetime is maximised. Numerical simulations on a test utility-owned microgrid demonstrate the effectiveness of the proposed model to reshape the loading of the distribution transformer at the point of interconnection in order to increase its lifetime.

description: We present a new technique for the numerical simulation of axisymmetric systems. This technique avoids the coordinate singularities which often arise when cylindrical or polar-spherical coordinate finite difference grids are used, particularly in simulating tensor partial differential equations like those of 3+1 numerical relativity. For a system axisymmetric about the z axis, the basic idea is to use a 3-dimensional Cartesian (x,y,z) coordinate grid which covers (say) the y=0 plane, but is only one finite-difference-molecule--width thick in the y direction. The field variables in the central y=0 grid plane can be updated using normal (x,y,z)--coordinate finite differencing, while those in the y \neq 0 grid planes can be computed from those in the central plane by using the axisymmetry assumption and interpolation. We demonstrate the effectiveness of the approach on a set of fully nonlinear test computations in 3+1 numerical general relativity, involving both black holes and collapsing gravitational waves.

description: Within a spin wave analysis and a fermionic large-n limit, it is shown that the antiferromagnetic Heisenberg model on the checkerboard lattice may have different ground states, depending on the spin size $S$. Through an additional exchange interaction that corresponds to an inter-tetrahedra coupling, the stability of the Néel state has been explored for all cases from the square lattice to the isotropic checkerboard lattice. Away from the isotropic limit and within the linear spin wave approximation, it is shown that there exists a critical coupling for which the local magnetization of the Néel state vanishes for any value of the spin $S$. One the other hand, using the Dyson-Maleev approximation, this result is valid only in the case $S= \frac12$ and the limit between a stable and an unstable Néel state is at S=1. For $S= \frac12$, the fermionic large-n limit suggests that the ground state is a valence bond solid build with disconnected 4-spins singlets. This analysis indicates that for low spin and in the isotropic limit, the checkerboard antiferromagnet may be close to an instability between an ordered S=0 ground state and a magnetized ground state.

Inertial Mass of a Vortex in Cuprate Superconductors

description: We present here a calculation of the inertial mass of a moving vortex in cuprate superconductors. This is a poorly known basic quantity of obvious interest in vortex dynamics. The motion of a vortex causes a dipolar density distortion and an associated electric field which is screened. The energy cost of the density distortion as well as the related screened electric field contribute to the vortex mass, which is small because of efficient screening. As a preliminary, we present a discussion and calculation of the vortex mass using a microscopically derivable phase-only action functional for the far region which shows that the contribution from the far region is negligible, and that most of it arises from the (small) core region of the vortex. A calculation based on a phenomenological Ginzburg-Landau functional is performed in the core region. Unfortunately such a calculation is unreliable, the reasons for it are discussed. A credible calculation of the vortex mass thus requires a fully microscopic, non-coarse grained theory. This is developed, and results are presented for a s-wave BCS like gap, with parameters appropriate to the cuprates. The mass, about 0.5 $m_e$ per layer, for magnetic field along the $c$ axis, arises from deformation of quasiparticle states bound in the core, and screening effects mentioned above. We discuss earlier results, possible extensions to d-wave symmetry, and observability of effects dependent on the inertial mass.

description: Extended defects such as stacking faults and anti-site domain boundaries can perturb the band edges in Cu$_2$ZnSnS$_4$ and Cu$_2$ZnSnSe$_4$, acting as a weak electron barrier or a source for electron capture, respectively. In order to find ways to prohibit the formation of planar defects, we investigated the effect of chemical substitution on the stability of the intrinsic stacking fault and metastable polytypes and analyze their electrical properties. Substitution of Ag for Cu makes stacking faults less stable, whereas the other substitutions (Cd and Ge) promote their formation. Ge substitution has no effect on the electron barrier of the intrinsic stacking fault, but Cd substitution reduces the barrier energy and Ag substitution makes the stacking fault electron capture. While Cd substitution stabilizes the stannite structure, chemical substitutions make the primitive-mixed CuAu (PMCA) structure less stable with respect to the ground-state kesterite structure.

description: We show that the 5-dimensional model introduced by Randall and Sundrum is (half of) a wormhole, and that this is a general result in models of the RS type. We also discuss the gravitational trapping of a scalar particle in 5-d spacetimes. Finally, we present a simple model of brane-world cosmology in which the background is a static anti-de Sitter manifold, and the location of the two 3-branes is determined by the technique of ``surgical grafting''.
