description: Lattice simulations have demonstrated that a background (electro)magnetic field reduces the chiral/deconfinement transition temperature of quantum chromodynamics for eB < 1 GeV^2. On the level of observables, this reduction manifests itself in an enhancement of the Polyakov loop and in a suppression of the light quark condensates (inverse magnetic catalysis) in the transition region. In this paper, we report on lattice simulations of 1+1+1-flavor QCD at an unprecedentedly high value of the magnetic field eB = 3.25 GeV^2. Based on the behavior of various observables, it is shown that even at this extremely strong field, inverse magnetic catalysis prevails and the transition, albeit becoming sharper, remains an analytic crossover. In addition, we develop an algorithm to directly simulate the asymptotically strong magnetic field limit of QCD. We find strong evidence for a first-order deconfinement phase transition in this limiting theory, implying the presence of a critical point in the QCD phase diagram. Based on the available lattice data, we estimate the location of the critical point.

description: The introduction and establishment of flexible work can be understood as a complex organizational development (OD) phenomenon, which includes culture, leadership, policies, technology, and office design (among others). In our study “GeMobAU” (Gestaltung mobil-flexibler Arbeit in grossen und mittleren Unternehmen – Design of mobile and flexible work in large and mid-sized companies), we tried to untangle the complexity around flexible work as an OD challenge. In order to achieve this, we conducted qualitative interviews, in pairs with teams and their supervisors in 13 cases in nine different companies, in which we discussed previous experiences as well as future expectations around flexible work on each of the five dimensions. Our analysis yielded distinctly different OD processes for beginner and advanced teams and organizations: While beginners had to cope with new requirements and competencies for employees, advanced organizations and teams expressed more concern about new leadership skills and styles that were needed, as well as finding the right technological solutions for highly mobile and distributed work.

description: We investigate parameterized algorithms for the NP-hard problem Min-Power Asymmetric Connectivity (MinPAC) that has applications in wireless sensor networks. Given a directed arc-weighted graph, MinPAC asks for a strongly connected spanning subgraph minimizing the summed vertex costs. Here, the cost of each vertex is the weight of its heaviest outgoing arc in the chosen subgraph. We present linear-time algorithms for the cases where the number of strongly connected components in a so-called obligatory subgraph or the feedback edge number in the underlying undirected graph is constant. Complementing these results, we prove that the problem is W[2]-hard with respect to the solution cost, even on restricted graphs with one feedback arc and binary arc weights.

description: In this work we study the reinforcement of polymers by mechanically interlocked derivatives of single-walled carbon nanotubes (SWNTs). We compare the mechanical properties of fibers made of polymers and of composites with pristine single-walled carbon nanotubes (SWNTs), mechanically interlocked derivatives of SWNTs (MINTs) and the corresponding supramolecular models. Improvements of both Young's modulus and tensile strength of up to 200 % were observed for the polystyrene-MINTs samples with an optimized loading of just 0.01 wt.%, while the supramolecular models with identical chemical composition and loading showed negligible or even detrimental influence. This behavior is found for three different types of SWNTs and two types of macrocycles. Molecular dynamics simulations show that the polymer adopts an elongated conformation parallel to the SWNT when interacting with MINT fillers, irrespective of the macrocycle chemical nature, whereas a more globular structure is taken upon facing with either pristine SWNTs or supramolecular models. The MINT composite architecture thus leads to a more efficient exploitation of the axial properties of the SWNTs and of the polymer chain at the interface, in agreement with experimental results. Our findings demonstrate that the mechanical bond imparts distinctive advantageous properties to SWNT derivatives as polymer fillers.

description: Braucht mobil-flexible Zusammenarbeit eine andere Führung? Diese Frage beschäftigte uns, als wir unsere Forschungsarbeiten der vergangenen Jahre zum Thema mobil-flexible Arbeit gesamthaft sichteten. Wir stiessen auf besondere Herausforderungen für das Führungshandeln und die Gestaltung der Führungsbeziehung sowie ein verändertes Selbstverständnis der Führungskraft. Beispielsweise dann, wenn im Bereich der Kommunikation insbesondere der Schreibstil beim Verfassen von E-Mails an Mitarbeitende oder die Bewertung von informellen Gesprächen in den Fokus gerät. Des Weiteren stellten sich zum Beispiel viele Fragen zur Mediennutzung, Leistungsmessung und Organisationsstruktur, wenn der Arbeitsort und die -zeit flexibel gewählt werden können. Aber sind das neue Führungsthemen? Haben diese Erkenntnisse einen Neuigkeitswert? Wir denken schon, denn auch wenn die gefundenen Führungsaspekte bereits als Themen der Führungsentwicklung bekannt sind, ist die jeweilige Herausforderung im Kontext mobil-flexibler Zusammenarbeit sehr gross und zum Teil auch ganz neu zu denken. Die Führungskräfte haben nicht nur neue Tools zu lernen, sondern es geht um nichts Geringeres als eine Veränderung der eigenen Haltung und Einstellung, was Führung bedeutet und wie sie gestaltet werden kann. Wir können aus unseren Studien zum Beispiel entnehmen, dass es enorm wichtig ist, gemeinsam im Team zu experimentieren, um zu neuen Regeln der Zusammenarbeit zu kommen. Bin ich es als Führungskraft jedoch gewohnt, die Prozesskontrolle im Hinblick auf ein von mir verantwortetes Ergebnis zu haben, muss ich mich an diesem Punkt mit mir selber auseinandersetzen: Bringe ich ausreichendes Vertrauen auf gegenüber dem Prozess des Experimentierens und meinen Mitarbeitenden? Halte ich die Ergebnisoffenheit nicht nur aus, sondern kann ich mich in das gemeinsame kreative Vorgehen auch produktiv einbringen?

description: The time-dependent Mott transition in a periodic Anderson model with off-site, nearest-neighbor hybridization is studied within the framework of nonequilibrium self-energy functional theory. Using the two-site dynamical-impurity approximation, we compute the real-time dynamics of the optimal variational parameter and of different observables initiated by sudden quenches of the Hubbard-U and identify the critical interaction. The time-dependent transition is orbital selective, i.e., in the final state, reached in the long-time limit after the quench to the critical interaction, the Mott gap opens in the spectral function of the localized orbitals only. We discuss the dependence of the critical interaction and of the final-state effective temperature on the hybridization strength and point out the various similarities between the nonequilibrium and the equilibrium Mott transition. It is shown that these can also be smoothly connected to each other by increasing the duration of a U-ramp from a sudden quench to a quasi-static process. The physics found for the model with off-site hybridization is compared with the dynamical Mott transition in the single-orbital Hubbard model and with the dynamical crossover found for the real-time dynamics of the conventional Anderson lattice with on-site hybridization.

description: Let $f:M\to \mathbb{R}$ be a Morse function on a smooth closed surface, $V$ be a connected component of some critical level of $f$, and $\mathcal{E}_V$ be its atom. Let also $\mathcal{S}(f)$ be a stabilizer of the function $f$ under the right action of the group of diffeomorphisms $\mathrm{Diff}(M)$ on the space of smooth functions on $M,$ and $\mathcal{S}_V(f) = \{h\in\mathcal{S}(f)\,| h(V) = V\}.$ The group $\mathcal{S}_V(f)$ acts on the set $π_0\partial \mathcal{E}_V$ of connected components of the boundary of $\mathcal{E}_V.$ Therefore we have a homomorphism $ϕ:\mathcal{S}(f)\to \mathrm{Aut}(π_0\partial \mathcal{E}_V)$. Let also $G = ϕ(\mathcal{S}(f))$ be the image of $\mathcal{S}(f)$ in $\mathrm{Aut}(π_0\partial \mathcal{E}_V).$ Suppose that the inclusion $\partial \mathcal{E}_V\subset M\setminus V$ induces a bijection $π_0 \partial \mathcal{E}_V\toπ_0(M\setminus V).$ Let $H$ be a subgroup of $G.$ We present a sufficient condition for existence of a section $s:H\to \mathcal{S}_V(f)$ of the homomorphism $ϕ,$ so, the action of $H$ on $\partial \mathcal{E}_V$ lifts to the $H$-action on $M$ by $f$-preserving diffeomorphisms of $M$. This result holds for a larger class of smooth functions $f:M\to \mathbb{R}$ having the following property: for each critical point $z$ of $f$ the germ of $f$ at $z$ is smoothly equivalent to a homogeneous polynomial $\mathbb{R}^2\to \mathbb{R}$ without multiple linear factors.

description: GJ676A is an M0 dwarf hosting both gas-giant and super-Earth-type planets discovered with radial-velocity measurements. Using FORS2/VLT, we obtained position measurements of the star in the plane of the sky that tightly constrain its astrometric reflex motion caused by the super-Jupiter planet `b` in a 1052-day orbit. This allows us to determine the mass of this planet to $M_\mathrm{b} = 6.7^{+1.8}_{-1.5}\,M_\mathrm{J}$, which is $\sim$40 \% higher than the minimum mass inferred from the radial-velocity orbit. Using new HARPS radial-velocity measurements, we improve upon the orbital parameters of the inner low-mass planets `d` and `e` and we determine the orbital period of the outer giant planet `c` to $P_\mathrm{c}=7340$ days under the assumption of a circular orbit. The preliminary minimum mass of planet `c` is $M_\mathrm{c} \sin i = 6.8\,M_\mathrm{J}$ with an upper limit of $\sim$$39\,M_\mathrm{J}$ that we set using NACO/VLT high-contrast imaging. We also determine precise parallaxes and relative proper motions for both GJ676A and its wide M3 companion GJ676B. Despite the probably mature age of the system, the masses and projected separations ($\sim$0.1" -- 0.4") of planets `b` and `c` make them promising targets for direct imaging with future instruments in space and on extremely large telescopes. In particular, we estimate that GJ676A b and GJ676A c are promising targets for directly detecting their reflected light with the WFIRST space mission. Our study demonstrates the synergy of radial-velocity and astrometric surveys that is necessary to identify the best targets for such a mission.

description: Long-term synoptic observations in the resonance line of Ca II K constitute a fundamental database for a variety of retrospective analyses of the state of the solar magnetism. Synoptic Ca II K observations began in late 1904 at the Kodaikanal Observatory, in India. In early 1970s, the National Solar Observatory (NSO) at Sacramento Peak (USA) started a new program of daily Sun-as-a-star observations in the Ca II K line. Today the NSO is continuing these observations through its Synoptic Optical Long-term Investigations of the Sun (SOLIS) facility. These different data sets can be combined into a single disk-integrated Ca II K index time series that describes the average properties of the chromospheric emission over several solar cycles. We present such a Ca II K composite and discuss its correlation with the new entirely revised sunspot number data series. For this preliminary investigation, the scaling factor between pairs of time series was determined assuming a simple linear model for the relationship between the monthly mean values during the duration of overlapping observations.

description: We numerically solve the underdamped Langevin equation to obtain the trajectories of a particle in a sinusoidal potential driven by a temporally sinusoidal force in a medium with coefficient of friction periodic in space as the potential but with a phase difference. With the appropriate choice of system parameters, like the mean friction coefficient and the period of the applied field, only two kinds of periodic trajectories are obtained for all possible initial conditions at low noise strengths: one with a large amplitude and a large phase lag with respect to the applied field and the other with a small amplitude and a small phase lag. Thus, the periodic potential system is effectively mapped dynamically into a bistable system. Though the directional asymmetry, brought about only by the frictional inhomogeneity, is weak we find both the phenomena of stochastic resonance, with ready explanation in terms of the two dynamical states of trajectories, and ratchet effect simultaneously in the same parameter space. We analyse the results in detail attempting to find plausible explanations for each.

description: Any physical system can be viewed from the perspective that information is implicitly represented in its state. However, the quantification of this information when it comes to complex networks has remained largely elusive. In this work, we use techniques inspired by quantum statistical mechanics to define an entropy measure for complex networks and to develop a set of information-theoretic tools, based on network spectral properties, such as Renyi q-entropy, generalized Kullback-Leibler and Jensen-Shannon divergences, the latter allowing us to define a natural distance measure between complex networks. First we show that by minimizing the Kullback-Leibler divergence between an observed network and a parametric network model, inference of model parameter(s) by means of maximum-likelihood estimation can be achieved and model selection can be performed appropriate information criteria. Second, we show that the information-theoretic metric quantifies the distance between pairs of networks and we can use it, for instance, to cluster the layers of a multilayer system. By applying this framework to networks corresponding to sites of the human microbiome, we perform hierarchical cluster analysis and recover with high accuracy existing community-based associations. Our results imply that spectral based statistical inference in complex networks results in demonstrably superior performance as well as a conceptual backbone, filling a gap towards a network information theory.

Where Does the Density Localize? Convergent Behavior for Global Hybrids, Range Separation, and DFT+U

description: Approximate density functional theory (DFT) suffers from many-electron self- interaction error, otherwise known as delocalization error, that may be diagnosed and then corrected through elimination of the deviation from exact piecewise linear behavior between integer electron numbers. Although paths to correction of energetic delocalization error are well- established, the impact of these corrections on the electron density is less well-studied. Here, we compare the effect on density delocalization of DFT+U, global hybrid tuning, and range- separated hybrid tuning on a diverse test set of 32 transition metal complexes and observe the three methods to have qualitatively equivalent effects on the ground state density. Regardless of valence orbital diffuseness (i.e., from 2p to 5p), ligand electronegativity (i.e., from Al to O), basis set (i.e., plane wave versus localized basis set), metal (i.e., Ti, Fe, Ni) and spin state, or tuning method, we consistently observe substantial charge loss at the metal and gain at ligand atoms (ca. 0.3-0.5 e or more). This charge loss at the metal is preferentially from the minority spin, leading to increasing magnetic moment as well. Using accurate wavefunction theory references, we observe that a minimum error in partial charges and magnetic moments occur at higher tuning parameters than typically employed to eliminate energetic delocalization error. These observations motivate the need to develop multi-faceted approximate-DFT error correction approaches that separately treat density delocalization and energetic errors in order to recover both correct density and magnetization properties.

description: We use the concept of entropy power to derive a new one-parameter class of information-theoretic uncertainty relations for pairs of conjugate observables in an infinite-dimensional Hilbert space. This class constitutes an infinite tower of higher-order statistics uncertainty relations, which allows one in principle to determine the shape of the underlying information-distribution function by measuring the relevant entropy powers. We illustrate the capability of the new class by discussing two examples: superpositions of vacuum and squeezed states and the Cauchy-type heavy-tailed wave function.

The ionic liquid monomers were first prepared via N-alkylation reaction of commercially available 1-vinyl-1,2,4-triazole with alkyl iodides, followed by anion metathesis with targeted fluorinated anions. The thermal properties and solubilities of these poly(ionic liquid)s have been systematically investigated. Interestingly, it was found that the poly(4-ethyl-1-vinyl-1,2,4-triazolium) poly(ionic liquid) exhibited an improved loading capacity of transition metal ions in comparison with its imidazolium counterpart.

Dabei können heutzutage längst nicht mehr alle auf die Unterstützung und insbesondere die Betreuung durch enge Familienangehörige (Partner:innen oder Kinder) zählen. Dies ist nicht sofort gleichzusetzen mit besonderer Vulnerabilität, kann bei mangelnden finanziellen oder sozialen Ressourcen und angesichts unzureichender sozialstaatlicher Rahmenbedingungen für Betreuung aber zum Problem werden. Gute Betreuung im Alter im Sinne einer «sorgenden Beziehungsarbeit» legt, unabhängig vom Grad der Pflegebedürftigkeit, den Fokus auf die psychosozialen Bedürfnisse der älteren Menschen und befähigt sie zu einem selbstbestimmten Leben. Doch während in der Schweiz auf die Unterstützungsformen der Hilfe und Pflege ein Anrecht besteht, fehlt dieses für die Betreuung im Alter, und die unentgeltliche Sorgearbeit durch Familienangehörige und informelle Netzwerke wird implizit vorausgesetzt.

description: We propose a new algorithm to detect the community structure in a network that utilizes both the network structure and vertex attribute data. Suppose we have the network structure together with the vertex attribute data, that is, the information assigned to each vertex associated with the community to which it belongs. The problem addressed this paper is the detection of the community structure from the information of both the network structure and the vertex attribute data. Our approach is based on the Bayesian approach that models the posterior probability distribution of the community labels. The detection of the community structure in our method is achieved by using belief propagation and an EM algorithm. We numerically verified the performance of our method using computer-generated networks and real-world networks.

description: Activated carbon derived from coconut shells underwent successful synthesis employing three distinct chemical activators: NaOH, H3 PO4, and ZnCl2. Harvested from highland regions with freshwater environments, coconut shells were solar thermally dried prior to carbonization at 600⁰C for 3 hours, followed by thorough activation. Characterization of the samples encompassed X-Ray Diffraction (XRD), Fourier Transform Infrared (FTIR), to discern crystal structure, functional groups, surface area, and morphology. XRD analysis revealed the formation of an amorphous phase with carbon graphite as the predominant constituent, while impurities such as hydrogen, oxygen, nitrogen, potassium, sodium, phosphorus, calcium, and magnesium were identified. FTIR spectroscopy indicated no significant discrepancies across the three activating agents, affirming successful activation through the presence of –OH, C=O, and C-O functional groups. These findings collectively endorse the potential applicability of coconut shell-based activated carbon in water purification treatments. The compacted activated carbon underwent cyclic voltammetry testing across varied scan rates ranging from 20 mV/s to 100 mV/s, within a potential window of 0.05 to 0.8. Specific capacitance values were recorded at each scan rate: 602.19 F/g, 299.78 F/g, 378.31 F/g, 374.13 F/g, and 286.92 F/g, respectively. Notably, the highest specific capacitance of 600.89 F/g and an energy density of 45.64 Wh/kg were achieved at a scan rate of 20 mV/s. Comparative analysis with prior research indicated that the synthesized activated carbon electrodes in this study exhibited the highest specific capacitance observed to date.

Cette situation n’est pas synonyme de vulnérabilité, mais peut devenir problématique lorsque les ressources financières ou sociales viennent à manquer et que les conditions-cadres de l’État social pour l’accompagnement sont lacunaires. Un bon accompagnement dans la vieillesse, dans le sens d’un « travail relationnel de care », met l’accent sur les besoins psychosociaux des personnes âgées et leur permet de mener une vie autodéterminée, indépendamment de leur degré de dépendance à des soins. Pourtant, s’il existe en Suisse un droit pour les formes de soutien que sont l’aide et les soins, ce droit n’existe pas pour l’accompagnement dans la vieillesse. Le travail de care non rémunéré par des proches de la famille et les réseaux informels est implicitement considéré comme acquis.

description: We study approximation properties of weighted $L^2$-orthogonal projectors onto spaces of polynomials of bounded degree in the Euclidean unit ball, where the weight is of the generalized Gegenbauer form $x \mapsto (1-\|x\|^2)^α$, $α> -1$. Said properties are measured in Sobolev-type norms in which the same weighted $L^2$ norm is used to control all the involved weak derivatives. The method of proof does not rely on any particular basis of orthogonal polynomials, which allows for a short, streamlined and dimension-independent exposition.

description: 2015 will see the first observations of Advanced LIGO and the start of the gravitational-wave (GW) advanced-detector era. One of the most promising sources for ground-based GW detectors are binary neutron-star (BNS) coalescences. In order to use any detections for astrophysics, we must understand the capabilities of our parameter-estimation analysis. By simulating the GWs from an astrophysically motivated population of BNSs, we examine the accuracy of parameter inferences in the early advanced-detector era. We find that sky location, which is important for electromagnetic follow-up, can be determined rapidly (~5 s), but that sky areas may be hundreds of square degrees. The degeneracy between component mass and spin means there is significant uncertainty for measurements of the individual masses and spins; however, the chirp mass is well measured (typically better than 0.1%).

description: Im Beitrag wird Lautes Denken als Methode vorgestellt und in seiner Bedeutung für die geschichts- und politikdidaktische Forschung verortet. Hierfür werden zunächst fachunspezifisch Hintergründe, Charakteristika und Leistungsfähigkeit der Methode eingeordnet. Im Anschluss werden bisherige Einsatzfelder Lauten Denkens in der Geschichts- und Politikdidaktik dargestellt. Während die Methode in der Geschichtsdidaktik in zahlreichen Zusammenhängen zum Einsatz kommt, ist sie in der Politikdidaktik noch weniger gebräuchlich. Die Zusammenschau mündet schliesslich in eine Diskussion der Reichweiten und Limitationen der Methode sowie die Benennung von Entwicklungsfeldern für beide Disziplinen.

description: Diese Arbeit beschreibt anhand einer detaillierten experimentellen Studie das System- und Versagensverhalten neuartiger Verbindungselemente aus Faser-Kunststoff-Verbund (FKV) bestehend aus Kohlenstofffasern (engl. carbon fibre = CF) und einer thermoplastischen Matrix Polyether-Etherketon (PEEK), die für konventionelle FKV-Verbindungen entwickelt wurden. Das System- und Versagensverhalten wird anhand einer einfach überlappenden Verbindung mit zwei CF-PEEK Senkkopfbolzen bei quasi-statischer Zug- und zyklischer Zug-Zug-Belastung mittels akustischer Emission untersucht. Die Ergebnisse stimmen gut mit dem entwickelten mathematischen Modell, einem auf Feder-Masse-Modell basierenden Ansatz, überein.
description: This Work presents a detailed experimental study on carbon fibre (CF) polyether etherketone (PEEK) composites fasteners designed to join conventional high performance composites (CFRP). The failure mechanisms of two CF-PEEK fasteners with countersunk heads joining two laminate plates in a single-lap configuration were investigated under static (tensile) and cyclic loading (tension-tension). The failure process of the bolted joints is described in detail using acoustic emission and microscopic cut views. The experimental results are in good agreement with the newly developed “closed-form” model. This enhanced analytical approach is a closed-form extension of the spring based method, where bolts and laminates are represented by an arrangement of springs and masses.
Factorization, resummation and sum rules for heavy-to-light form factors

description: Precision calculations of heavy-to-light form factors are essential to sharpen our understanding towards the strong interaction dynamics of the heavy-quark system and to shed light on a coherent solution of flavor anomalies. We briefly review factorization properties of heavy-to-light form factors in the framework of QCD factorization in the heavy quark limit and discuss the recent progress on the QCD calculation of $B \to π$ form factors from the light-cone sum rules with the $B$-meson distribution amplitudes. Demonstration of QCD factorization for the vacuum-to-$B$-meson correlation function used in the sum-rule construction and resummation of large logarithms in the short-distance functions entering the factorization theorem are presented in detail. Phenomenological implications of the newly derived sum rules for $B \to π$ form factors are further addressed with a particular attention to the extraction of the CKM matrix element $|V_{ub}|$.

description: History lessons in secondary schools aim at fostering competences in historical thinking. A part of this is the competence to differentiate between historical sources and depictions. In our article we outline how the classroom use of the web app Travis Go can contribute to fostering historical competences. Drawing on literature from teaching methodology, we discuss a scheme for an audiovisual media analysis on a macro and micro level. An example analysis of an excerpt from a TV documentary shows how the functions of Travis Go can be used to meet history teaching and media education requirements.
Transport and selective chaining of bidisperse particles in a travelling wave potential

description: We combine experiments, theory and numerical simulation to investigate the dynamics of a binary suspension of paramagnetic colloidal particles dispersed in water and transported above a stripe patterned magnetic garnet film. The substrate generates a one-dimensional periodic energy landscape above its surface. The application of an elliptically polarized rotating magnetic field causes the landscape to translate, inducing direct transport of paramagnetic particles placed above the film. The ellipticity of the applied field can be used to control and tune the interparticle interactions, from net repulsive to net attractive. When considering particles of two distinct sizes, we find that, depending on their elevation above the surface of the magnetic substrate, the particles feel effectively different potentials, resulting in different mobilities. We exploit this feature to induce selective chaining for certain values of the applied field parameters. In particular, when driving two types of particles, we force only one type to condense into travelling parallel chains. These chains confine the movement of the other non-chaining particles within narrow colloidal channels. This phenomenon is explained by considering the balance of pairwise magnetic forces between the particles and their individual coupling with the travelling landscape.

description: We study self-oscillations of an optomechanical system, where coherent mechanical oscillations are induced by a driven optical or microwave cavity, for the case of an anharmonic mechanical oscillator potential. A semiclassical analytical model is developed to characterize the limit cycle for large mechanical amplitudes corresponding to a weak nonlinearity. As a result, we predict conditions to achieve subpoissonian phonon statistics in the steady state, indicating classically forbidden behavior. We compare with numerical simulations and find very good agreement. Our model is quite general and can be applied to other physical systems such as trapped ions or superconducting circuits.
