description: We consider the non-equilibrium time evolution of piecewise homogeneous states in the XXZ spin-1/2 chain, a paradigmatic example of an interacting integrable model. The initial state can be thought as the result of joining chains with different global properties. Through dephasing, at late times the state becomes locally equivalent to a stationary state which explicitly depends on position and time. We propose a kinetic theory of elementary excitations and derive a continuity equation which fully characterizes the thermodynamics of the model. We restrict ourselves to the gapless phase and consider cases where the chains are prepared: 1) at different temperatures; 2) in the ground state of two different models; 3) in the "domain wall" state. We find excellent agreement (any discrepancy is within the numerical error) between theoretical predictions and numerical simulations of time evolution based on TEBD algorithms. As a corollary, we unveil an exact expression for the expectation values of the charge currents in a generic stationary state.

description: We study the texture of helical currents in metallic planar strips in the presence of Rashba spin-orbit coupling (RSOC) on the lattice at zero temperature. In the noninteracting case, and in the absence of external electromagnetic sources, we determine by exact numerical diagonalization of the single-particle Hamiltonian, the distribution across the strip section of these Rashba helical currents (RHC) as well as their sign oscillation, as a function of the RSOC strength, strip width, electron filling, and strip boundary conditions. Then, we study the effects of charge currents introduced into the system by an Aharonov-Bohm flux for the case of rings or by a voltage bias in the case of open strips. The former setup is studied by variational Monte Carlo, and the later, by the time-dependent density-matrix-renormalization group technique. Particularly for strips formed by two, three and four coupled chains, we show how these RHC vary in the presence of such induced charge current, and how their differences between spin-up and spin-down electron currents on each chain, help to explain the distribution across the strip of charge currents, both of the spin conserving and the spin flipping types. We also predict the appearance of polarized charge currents on each chain. Finally, we show that these Rashba helical currents and their derived features remain in the presence of an on-site Hubbard repulsion as long as the system remains metallic, at quarter filling, and even at half-filling where a Mott-Hubbard metal-insulator transition occurs for large Hubbard repulsion.

description: Gravity plays a determining role in the evolution of the molecular ISM. In \citet{2016arXiv160304342L}, we proposed a measure called gravitational energy spectrum to quantify the importance of gravity on multiple physical scales. In this work, using a wavelet-based decomposition technique, we derive the gravitational energy spectra of the Orion A and the Orion B molecular cloud from observational data. The gravitational energy spectra exhibit power-law-like behaviours. From a few pc down to $\sim 0.1 $ pc scale, the Orion A and Orion B molecular cloud have $E_{\rm p}(k)\sim k^{-1.88}$ and $E_{\rm p}(k)\sim k^{-2.09}$, respectively. These scaling exponents are close to the scaling exponents of the kinetic energy power spectrum of compressible turbulence (where $E\sim k^{-2}$), with a near-equipartition of turbulent versus gravitational energy on multiple scales. This provides a clear evidence that gravity is able to counteract effectively against turbulent motion for these length scales. The results confirm our earlier analytical estimates. For the Orion A molecular cloud, gravity inevitably dominates over turbulence inside the cloud. Our results provide a clear observational proof that gravity is playing a determining role in the evolution these molecular clouds from the cloud scale down to $\sim 0.1\;\rm pc$. { However, turbulence is likely to dominate in clouds like California. } The method is general and should be applicable to all the astrophysical problems where gravity plays a role.

description: The first known magnetic mineral, magnetite (Fe$_3$O$_4$), has unusual properties which have fascinated mankind for centuries; it undergoes the Verwey transition at $T_{\rm V}$ $\sim$120 K with an abrupt change in structure and electrical conductivity. The mechanism of the Verwey transition however remains contentious. Here we use resonant inelastic X-ray scattering (RIXS) over a wide temperature range across the Verwey transition to identify and separate out the magnetic excitations derived from nominal Fe$^{2+}$ and Fe$^{3+}$ states. Comparison of the RIXS results with crystal-field multiplet calculations shows that the spin-orbital $dd$ excitons of the Fe$^{2+}$ sites arise from a tetragonal Jahn-Teller active polaronic distortion of the Fe$^{2+}$O$_6$ octahedra. These low-energy excitations, which get weakened for temperatures above 350 K but persist at least up to 550 K, are distinct from optical excitations and best explained as magnetic polarons.

Optimizing evolutionary computation with hierarchy-based fitness functions for improved performance and efficiency

Subjects: classificationCode: 40

description: Research often focuses on improving performance and efficiency at a lower cost than the current state-of-the-art; one approach, which has enjoyed some success, is the use of various hierarchical models, particularly when trying to improve the scaling ability of Evolutionary Algorithms (EAs). The central hypothesis of this thesis is that by implementing hierarchy in fitness functions, which are at the core of EAs, one can reduce computational costs and improve performance.We initially develop a hierarchical system known as Pyramid, in which problems are decomposed into simpler versions that can be more easily solved, before scaling up to more difficult versions while reducing the population size. The scaling involves promoting high-performing individuals once they attain a certain threshold of fitness. A major research question in Pyramid is when to promote individuals to the next level (indicated by α), and another is how many individuals to promote (indicated by β). These choices were initially made arbitrarily.As part of our analysis, we use a set of GA benchmark problems to demonstrate that Pyramid is capable of at least the same performance in terms of solution quality on these benchmarks but at a considerably lower cost in terms of the number of individuals evaluated.Next, we improve Pyramid by introducing a refined threshold value of α to ensure that the top individuals are highly significantly better than the original population at the current level and making β less aggressive (to maintain a moderately sized population at the final level).As an extension of Pyramid, we propose Hierarchical Multi-Objective Symbolic Regression (HMS), where multiple objectives are arranged hierarchically. HMS works on two levels. At the first level, a random population is evolved based on a single objective (accuracy), and when the promotional criterion, also referred to as α, is met, some members of the population are promoted to the next level, where another objective (complexity) is introduced. This new, smaller population subsequently evolves using Multi-Objective Optimization (MOO). Several complexity measures are tested along with performance (accuracy). HMS is validated using synthetic Symbolic Regression (SR) problems, benchmarked against state-of-the-art solutions, as demonstrated by the best paper presented at GECCO 2022, where the authors utilized similar problems for evaluation. The evolved models are either competitive with or better than models produced with standard approaches in terms of performance. In terms of size, the solutions are more efficient, lowering computational costs.The hierarchical approaches we propose can benefit both GA and GP. Hierarchies are implemented from 2 to 5 levels, and the system is scalable to include more levels if needed. The performance is better or equal to the current state of the art, but our approaches are less computationally expensive.
Stochastic Effects in a Discretized Kinetic Model of Economic Exchange

description: Linear stochastic models and discretized kinetic theory are two complementary analytical techniques used for the investigation of complex systems of economic interactions. The former employ Langevin equations, with an emphasis on stock trade; the latter is based on systems of ordinary differential equations and is better suited for the description of binary interactions, taxation and welfare redistribution. We propose a new framework which establishes a connection between the two approaches by introducing stochastic effects into the kinetic model based on Langevin and Fokker-Planck formalisms. Numerical simulations of the resulting model indicate positive correlations between the Gini index and the total wealth, that suggests a growing inequality with increasing income. Further analysis shows a simultaneous decrease in inequality as social mobility increases in presence of a conserved total wealth, in conformity with economic data.

description: Wood fiber substrates perform well for lettuce seedlings production in speedling trays compared to standard commercially used press pots as well as growing media on peat base. Wood fibers contain a high air volume to allow higher levels of water tension without danger of water saturation in the substrate. For optimum growth they require a "high" matric potential. For cultivation of lettuce seedlings irrigation pulses at phi = -30 to -50 hPa are recommended in ebb and flood cultivation systems. This will provide good rooting and the least amount of proline, an indicator for plant stress. Accumulation of proline in lettuce seedlings could only be proved under conditions of visible stress symptoms. Not only water tension, but also the substrates in raising systems influence the free content of proline. At phi = -200 hPa proline in lettuce seedlings cultivated in a peat based press pots were ca. 40 % lower compare to seedlings in a wood fiber substrate in speedling trays. The difference in proline content between well-watered and stressed seedlings was smaller than with tomato transplants. Also, the correlation between proline content of lettuce seedlings and critical water tension for irrigation pulses was lower than with tomato transplant. The lettuce plants performed well after transplanting and no differences derived from seedling-treatments were recorded.

description: Lymphatic vessels are indispensable for tissue fluid homeostasis, transport of solutes and dietary lipids and immune cell trafficking. In contrast to blood vessels, which are easily visible by their erythrocyte cargo, lymphatic vessels are not readily detected in the tissue context. Their invisibility interferes with the analysis of the three-dimensional lymph vessel structure in large tissue volumes and hampers dynamic intravital studies on lymphatic function and pathofunction. An approach to overcome these limitations are mouse models, which express transgenic fluorescent proteins under the control of tissue-specific promotor elements. We introduce here the BAC-transgenic mouse reporter strain Vegfr3-tdTomato that expresses a membrane-tagged version of tdTomato under control of Flt4 regulatory elements. Vegfr3-tdTomato mice inherited the reporter in a mendelian fashion and showed selective and stable fluorescence in the lymphatic vessels of multiple organs tested, including lung, kidney, heart, diaphragm, intestine, mesentery, liver and dermis. In this model, tdTomato expression was sufficient for direct visualisation of lymphatic vessels by epifluorescence microscopy. Furthermore, lymph vessels were readily visualized using a number of microscopic modalities including confocal laser scanning, light sheet fluorescence and two-photon microscopy. Due to the early onset of VEGFR-3 expression in venous embryonic vessels and the short maturation time of tdTomato, this reporter offers an interesting alternative to Prox1-promoter driven lymphatic reporter mice for instance to study the developmental differentiation of venous to lymphatic endothelial cells.

description: We derive a family of exact solutions for bi-metric gravity with an exchange symmetry between the two metrics. In this two-parameter family of solutions the gravitational field is sourced by a time-independent massless scalar field. We find that the only limit in which the scalar field entirely vanishes is flat space. The regular Schwarzschild-solution is left with a scalar field hidden in the second metric's sector.

description: In this paper we study the triaxial properties of dark matter haloes of a wide range of masses extracted from a set of cosmological N-body simulations. We measure the shape at different distances from the halo centre (characterised by different overdensity thresholds), both in three and in two dimensions. We discuss how halo triaxiality increases with mass, redshift and distance from the halo centre. We also examine how the orientation of the different ellipsoids are aligned with each other and what is the gradient in internal shapes for halos with different virial configurations. Our findings highlight that the internal part of the halo retains memory of the violent formation process keeping the major axis oriented toward the preferential direction of the in-falling material while the outer part becomes rounder due to continuous isotropic merging events. This effect is clearly evident in high mass haloes - which formed more recently - while it is more blurred in low mass haloes. We present simple distributions that may be used as priors for various mass reconstruction algorithms, operating in different wavelengths, in order to recover a more complex and realistic dark matter distribution of isolated and relaxed systems.

description: This is the third in a series of papers that develop a new and flexible model to predict weak-lensing (WL) peak counts, which have been shown to be a very valuable non-Gaussian probe of cosmology. In this paper, we compare the cosmological information extracted from WL peak counts using different filtering techniques of the galaxy shear data, including linear filtering with a Gaussian and two compensated filters (the starlet wavelet and the aperture mass), and the nonlinear filtering method MRLens. We present improvements to our model that account for realistic survey conditions, which are masks, shear-to-convergence transformations, and non-constant noise. We create simulated peak counts from our stochastic model, from which we obtain constraints on the matter density $Ω_\mathrm{m}$, the power spectrum normalisation $σ_8$, and the dark-energy parameter $w_0$. We use two methods for parameter inference, a copula likelihood, and approximate Bayesian computation (ABC). We measure the contour width in the $Ω_\mathrm{m}$-$σ_8$ degeneracy direction and the figure of merit to compare parameter constraints from different filtering techniques. We find that starlet filtering outperforms the Gaussian kernel, and that including peak counts from different smoothing scales helps to lift parameter degeneracies. Peak counts from different smoothing scales with a compensated filter show very little cross-correlation, and adding information from different scales can therefore strongly enhance the available information. Measuring peak counts separately from different scales yields tighter constraints than using a combined peak histogram from a single map that includes multiscale information. Our results suggest that a compensated filter function with counts included separately from different smoothing scales yields the tightest constraints on cosmological parameters from WL peaks.

description: The Density Matrix Renormalization Group (DMRG) is a state-of-the-art numerical technique for a one dimensional quantum many-body system; but calculating accurate results for a system with Periodic Boundary Condition (PBC) from the conventional DMRG has been a challenging job from the inception of DMRG. The recent development of the Matrix Product State (MPS) algorithm gives a new approach to find accurate results for the one dimensional PBC system. The most efficient implementation of the MPS algorithm can scale as O($p \times m^3$), where $p$ can vary from 4 to $m^2$. In this paper, we propose a new DMRG algorithm, which is very similar to the conventional DMRG and gives comparable accuracy to that of MPS. The computation effort of the new algorithm goes as O($m^3$) and the conventional DMRG code can be easily modified for the new algorithm.

Natürliche und künstliche Quellen optischer Strahlung verursachen erwünschte und unerwünschte Wirkungen an der Haut und am gesamten Menschen.

Gesondert für Ultraviolettstrahlung, Licht und Infrarotstrahlung wird über die Wirkmechanismen im Organismus, unerwünschte und erwünschte Effekte einschließlich therapeutischer Anwendungen berichtet.
description: Optical radiation ranges from short wave ultraviolet via visible light to the far infra-red. Both natural and artificial light sources may cause desired and undesired effects, both on the skin and on the organism as a whole. The nature and extent of such effects depend primarily on the energy of the photons, the absorption capacity of the chromophores, the mean depth of penetration, and on the density and dose of the radiation. The present paper discusses the mechanisms of action and desired and undesired effects in the organism, including therapeutic applications, separately for ultraviolet radiation, visible light and infrared radiation.

description: Turbulent-laminar patterns are ubiquitous near transition in wall-bounded shear flows. Despite recent progress in describing their dynamics in analogy to non-equilibrium phase transitions, there is no theory explaining their emergence. Dynamical-system approaches suggest that invariant solutions to the Navier--Stokes equations, such as traveling waves and relative periodic orbits in pipe flow, act as building blocks of the disordered dynamics. While recent studies have shown how transient chaos arises from such solutions, the ensuing dynamics lacks the strong fluctuations in size, shape and speed of the turbulent spots observed in experiments. We here show that chaotic spots with distinct dynamical and kinematic properties merge in phase space and give rise to the enhanced spatio-temporal patterns observed in pipe flow. This paves the way for a dynamical-system foundation to the phenomenology of turbulent-laminar patterns in wall-bounded extended shear flows.
description: Implemented changes after peer review. Besides some minor tweaking the major ones were: The new title better reflects the scope of the paper. We have rewritten Section V to make a more compelling case. The caption of Figure 6 more clearly describes the global dynamics close to the boundary crisis. In the conclusion we now discuss the challenge of addressing the problem in full space

description: We perform large-scale field theoretical simulations in expanding universe to characterize a network of strings that can form composed bound states. The network consists of two copies of Abelian Higgs strings (which we label p and q, respectively) coupled via a potential term to give pq bound states. The simulations are performed using two different kinds of initial conditions: the first one with a network of p- and q-strings, and the second one with a network of q- and pq-strings. This way, we start from two opposite situations: one with no initial pq-strings, and one with a large initial number of pq-strings. We find that in both cases the system scales, and in both cases the system prefers to have a low fraction of pq-strings. This is somewhat surprising in the case for the second type of conditions, showing that the unzipping mechanism is very efficient. We also find hints that both initial conditions tend to asymptote to a common configuration, though we would need a larger dynamical range to confirm it. The average velocities of the different types of strings in the network have also been explored for the first time.

description: We develop sufficient analytic conditions for conservativeness of non-sectorial perturbations of symmetric Dirichlet forms which can be represented through a carré du champ on a locally compact separable metric space. These form an important subclass of generalized Dirichlet forms which were introduced in \cite{St1}. In case there exists an associated strong Feller process, the analytic conditions imply conservativeness, i.e. non-explosion of the associated process in the classical probabilistic sense. As an application of our general results on locally compact separable metric state spaces, we consider a generalized Dirichlet form given on a closed or open subset of $\mathbb{R}^d$ which is given as a divergence free first order perturbation of a symmetric energy form. Then using volume growth conditions of the carré du champ and the non-sectorial first order part, we derive an explicit criterion for conservativeness. We present several concrete examples which relate our results to previous ones obtained by different authors. In particular, we show that conservativeness can hold for a cubic variance if the drift is strong enough to compensate it. This work continues our previous work on transience and recurrence of generalized Dirichlet forms.

title: Illiberal Cultural Christianity? European Identity Constructions and Anti-Muslim Politics
Creators: name: Hennig, Anja

Subjects: subject: 320 Political science (Politics and government)

description: This paper refers to the ambivalence of secularization in order to explain why Cultural Christianity can show both a liberal and illiberal character. These two faces of Cultural Christianity are mostly due to the identity functions that, not only faith-based religion, but a particularly culturalized version of religion, entails. Proceeding from this, it will be demonstrated here how Cultural Christianity can turn into a concrete illiberal marker of identity or a resource for illiberal collective identity. Our argument focuses on the link between right-wing nationalism and Cultural Christianity from a historical-theoretical perspective, and illustrates the latter with the example of contemporary illiberal and selective European memory constructions including a special emphasis on the exclusivist elements.

description: We start by delineating the importance of RRI and how and why the European Commission adopted it. Then we zoom into the European Education policies and try to understand how RRI fits into these policies. We proceed by summarizing the recommendations that we found relevant for this topic and present those from three different angles: 1) organizational aspects and identity, 2) policy makers and 3) educators. Here, we summarize published recommendations and provide useful resources for policy makers and educators to help them integrate RRI in their organizations. By following these recommendations, universities and educational institutions can be a step closer to make science and education more inclusive and responsive to societal needs.
Serre weights and wild ramification in two-dimensional Galois representations

description: A generalization of Serre's Conjecture asserts that if $F$ is a totally real field, then certain characteristic $p$ representations of Galois groups over $F$ arise from Hilbert modular forms. Moreover it predicts the set of weights of such forms in terms of the local behavior of the Galois representation at primes over $p$. This characterization of the weights, which is formulated using $p$-adic Hodge theory, is known under mild technical hypotheses if $p > 2$. In this paper we give, under the assumption that $p$ is unramified in $F$, a conjectural alternative description for the set of weights. Our approach is to use the Artin-Hasse exponential and local class field theory to construct bases for local Galois cohomology spaces in terms of which we identify subspaces that should correspond to ones defined using $p$-adic Hodge theory. The resulting conjecture amounts to an explicit description of wild ramification in reductions of certain crystalline Galois representations. It enables the direct computation of the set of Serre weights of a Galois representation, which we illustrate with numerical examples. A proof of this conjecture has been announced by Calegari, Emerton, Gee and Mavrides.

description: Understanding the collective dynamics in a many-body system has been a central task in condensed matter physics. To achieve this task, we develop a Hartree-Fock theory to study the collective oscillations of spinor Fermi system, motivated by recent experiment on spin-9/2 fermions. We observe an oscillation period shoulder for small rotation angles. Different from previous studies, where the shoulder is found connected to the resonance from periodic to running phase, here the system is always in a running phase in the two-body phase space. This shoulder survives even in the many-body oscillations, which could be tested in the experiments. We also show how these collective oscillations evolve from two- to many-body. Our theory provides an alternative way to understand the collective dynamics in large-spin Fermi systems.
