description: In der Arbeit wird über die Ergebnisse empirischer Studien zur Einstellung von LehrerInnen in unterschiedlichen schulischen Settings zur Frage der Integration von SchülerInnen mit sonderpädagogischem Förderbedarf berichtet. Die Datensätze der Befragungen von insgesamt 578 LehrerInnen in der Grundschulstufe in Österreich aus den Jahren 1998 und 2009 wurden gemeinsam neu analysiert. Als Untersuchungsinstrument diente die Skala „Einstellung zur Integration in der Schule (EIS)“ von Reicher (1988). Hinsichtlich der Reliabilität und der faktoriellen Struktur entspricht die Skala den Anforderungen, die an ein Forschungsinstrument zu stellen sind. Die inhaltliche Auswertung der erhobenen Daten zeigte, dass die LehrerInnen die Integration von SchülerInnen mit einer geistigen Behinderung als schwieriger einschätzten als die Integration von SchülerInnen mit einer körperlichen Behinderung oder einer Lernbehinderung. In Bezug auf die generelle Einstellung zur schulischen Integration ergaben sich keine Unterschiede zwischen SonderschullehrerInnen und GrundschullehrerInnen, es zeigte sich aber ein moderater Effekt des Arbeitsfeldes, in dem die Befragten arbeiteten. LehrerInnen in integrativen Arbeitsfeldern gaben in Bezug auf jede Art der Behinderung eine positivere Einstellung zur schulischen Integration an als LehrerInnen in nicht-integrativen Settings.

Subjects: Sports science and exercise not elsewhere classified

description: Obtaining sufficient sleep is important for humans to maintain optimal performance. This is especially true for elite athletes striving to improve performance while contending with unique stimuli that may impact their sleep (e.g., training, competition, travel). Measurement tools, countermeasures, and/or strategies that can be used to mitigate factors that negatively affect sleep are of great interest to athletes, coaches, and practitioners. This dissertation addresses (1) the validity of a wearable device to measure sleep; (2) the impact of evening exercise modality on sleep; (3) the effectiveness of strategies to facilitate circadian adaptation following transmeridian travel; and (4) the effectiveness of combined nutritional ingredients on sleep.

description: We report on measurements of three-body recombination rates in an ultracold gas of $^7$Li atoms in the extremely nonuniversal regime where the two-body scattering length vanishes. We show that the rate is well defined and can be described by two-body parameters only: the scattering length $a$ and the effective range $R_e$. We find the rate to be energy independent, and, by connecting our results with previously reported measurements in the universal limit, we cover the behavior of the three-body recombination in the whole range from weak to strong two-body interactions. We identify a nontrivial magnetic field value in the nonuniversal regime where the rate should be strongly reduced.

Central molecular zones in galaxies: multitransition survey of dense gas tracers HCN, HNC, and HCO+

description: New HCN, HNC, and HCO+ measurements of 46 normal galaxies in transitions up to J=4-3 are included in a multitransition database covering HCN and HCO+ (130 galaxies) and HNC (94 galaxies). The near-linear luminosity relations are dominated by distance effects and do not reflect galaxy physical properties. Individual galaxies show significant dispersion in both their luminosity and line ratio. Line ratios do not correlate well with either luminosities or other line ratios. Only the normalized J-transition ladders of HCN and HCO+ and the J=1-0 12CO/13CO isotopologue ratio are positively correlated with CO and far infrared (FIR) luminosity. The HCN and HCO+ molecules have very similar intensities and trace the same gas. In galaxies dominated by an active nucleus, HCO+ intensities are depressed relative to HCN intensities. Only a small fraction of the CO emission is directly associated with gas emitting in HCN and HCO, yet a significant fraction of even that gas appears to be translucent molecular gas. In the observed galaxy centers, the HCN/CO line intensity ratio is not a proxy for the dense gas fraction. Likewise, the FIR/HCN and FIR/CO ratios are not proxies for the star formation efficiency. The observed molecular line emission is fully consistent with UV-photon heating boosted by significant mechanical heating. The molecular gas sampled by HCN and HCO+ has low kinetic temperatures T(kin)=10-50 K, low densities n(H)=10^4-10^5 cm^(-3), and low optical depths in the ground-state lines. Most of the gas sampled by CO has densities lower by one to two orders of magnitude. For a mechanical heating fraction of 0.5, a modest energy input of only G=300 Go is required. A proper understanding of star formation requires a more appropriate determination of the gas mass than provided by the intensities of individual HCN or CO transitions.

Modified model of top quark condensation

Year: 2014
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We develop the modification of the top - quark condensation scenario, in which the Higgs boson is composed of all Standard Model fermions. Within this scenario we suggest the phenomenological model with non - local four - fermion interactions in which at the distances of the order of $\sim 1/100$ GeV the theory is represented in terms of only one Majorana spinor that carries the $U(12)$ index and, in addition, belongs to the spinor representation of $O(4)$. The Standard Model fermions are the components of this spinor. The symmetry $U(12)\otimes O(4)$ is responsible for the one - loop relation between the Higgs boson mass and the top quark mass $M_H^2 = m_t^2/2$. At the distances $\gg 1/100$ GeV the mentioned symmetry is broken, and the interaction term dominates that provides the nonzero mass of the top quark. Our phenomenological model should be considered in zeta or dimensional regularization. In conventional cutoff regularization this is equivalent to the existence of the additional counter - terms that cancel all quadratic divergences. As a result the $1/N$ expansion may be applied.

description: Covariant Lyapunov vectors for scale-free networks of Henon maps are highly localized. We revealed two mechanisms of the localization related to full and phase cluster synchronization of network nodes. In both cases the localization nodes remain unaltered in course of the dynamics, i.e., the localization is nonwandering. Moreover this is predictable: the localization nodes are found to have specific dynamical and topological properties and they can be found without computing of the covariant vectors. This is an example of explicit relations between the system topology, its phase space dynamics, and the associated tangent space dynamics of covariant Lyapunov vectors.

description: Neste trabalho, foi feita a replicação do experimento de Millikan utilizando o arranjo e procedimentos previamente utilizados nas disciplinas experimentais do IFUSP visando identificar e caracterizar as fontes de erros e ruídos e propor melhorias. Foi diagnósticado que a iluminação e limitações técnicas da câmera são os maiores empecilhos no arranjo antigo; além disso, verificou-se que a falta de ajustes finos no arranjo óptico e de um método padronizado de análise de dados dificultam a replicabilidade do experimento. Foi experimentado, então, o uso de diferentes iluminações, bem como de um sistema de aquisição e análise de dados baseado em Raspberry Pi e Python3.

description: The properties of the deformed halo of 31Ne were discussed using the antisymmetrized molecular dynamics plus resonating group method (AMD+RGM). The AMD+RGM calculations describe a large neutron radius for the ground state and reveal that the ground state is dominated by core-excited components. The resonant states were also investigated by applying the analytical continuation of the coupling constant. It was found that the first excited state (the 5/2- state) is also dominated by core-excited components and has a small decay width, whereas the second excited state (the 7/2- state) is dominated by the valence neutron in the $f$-wave coupled to the ground state of 30Ne.

description: This work assesses the performance of the recently proposed global natural orbital functional (GNOF) against the charge delocalization error. GNOF provides a good balance between static and dynamic electronic correlation leading to accurate total energies while preserving spin, even for systems with a highly multi-configurational character. Several analyses were applied to the functional, namely i) how the charge is distributed in super-systems of two fragments, ii) the stability of ionization potentials while increasing the system size, and iii) potential energy curves of a neutral and charged diatomic system. GNOF was found to practically eliminate the charge delocalization error in many of the studied systems or greatly improves the results obtained previously with PNOF7.

description: In a survey 840 parents of children with cognitive deficits who were educated either in special schools or in inclusive classes, they were asked to assess their children’s school experiences. The results showed an overall high degree of satisfaction with the schooling, but there were marked differences among the parents' assessments depending on the degree of learning disabilities and on the type of school. Satisfaction with their children’s social experiences and satisfaction with the special education curriculum depend on these two factors. All in all, more parents of children in inclusive classes were satisfied with their children’s schooling than those with children in special schools. The analysis of the causes for discontent showed that dissatisfied parents had chosen the type of school under less favourable conditions and a larger part of them is still not convinced of this necessity of additional help. This applied to parents of pupils in inclusive classes as well as to those in special schools. Furthermore, parents of children with German as a second language showed a higher degree of discontent than others.

description: Der vorliegende Artikel untersucht das Sozialverhalten und die sozialen Kompetenzen in Beziehung zur sozialen Integration von SchülerInnen in Integrationsklassen. Dazu wurden 179 SchülerInnen mit und ohne sonderpädagogischem Förderbedarf (SPF) aus acht Grazer Integrationsklassen am Ende der 5. Schulstufe untersucht. Die SchülerInnen mit SPF fühlten sich emotional ähnlich gut integriert als SchülerInnen ohne SPF, bei der sozialen Integration war dies jedoch nicht der Fall. SchülerInnen mit SPF haben einen signifikant niedrigeren Mittelwert als SchülerInnen ohne SPF in der sozialen Integration. Mittels Regressionsanalyse konnte jedoch gezeigt werden, dass nicht der SPF die erklärende Variable für diese Diskrepanz ist, sondern die soziale Integration durch die direkte Viktimisierung (Peereinschätzung), das prosoziales Verhalten der Peers (Peereinschätzung) und die Viktimisierung (LehrerInneneinschätzung) vorhergesagt werden kann.

description: We investigate properties of the $N$(nucleon)-$Ω$(Omega) interaction in lattice QCD to seek for possible dibaryon states in the strangeness $-3$ channel. We calculate the $NΩ$ potential through the equal-time Nambu-Bethe-Salpeter wave function in 2+1 flavor lattice QCD with the renormalization group improved Iwasaki gauge action and the nonperturbatively $\mathcal{O}(a)$ improved Wilson quark action at the lattice spacing $a\simeq 0.12$ fm on a (1.9 fm)$^{3}\times$ 3.8 fm lattice. The $ud$ and $s$ quark masses in our study correspond to $m_π= 875(1)$ MeV and $m_{K}= 916(1)$ MeV. At these parameter values, the central potential in the S-wave with the spin 2 shows attractions at all distances.By solving the Schrödinger equation with this potential, we find one bound state whose binding energy is $18.9(5.0)(^{+12.1}_{-1.8})$ MeV, where the first error is the statistical one, while the second represents the systematic error.

description: Class placement alone cannot be seen as a determining factor for inclusive education. The present study analyses the link between and social and emotional integration and social behavior. Self- and teacher-assessed social behavior as well as self-estimated social and emotional integration were analyzed in a sample of 179 fifth graders from integration classes in Austria. The comparisons between students with and without special education needs (SEN) illustrate that students with SEN showed more indirect aggressive behavior and less pro-social behavior than students without SEN. Regarding the emotional integration, students with SEN felt as well integrated as students without SEN; nevertheless they felt less integrated socially. Relationships between social behavior and self-estimated social and emotional integration were found; especially pro-social behavior and victimization play an important role in both subgroups. These results suggest that the social behavior of all students in integration classes deserves attention.
Large tensor spectrum of BICEP2 in the natural SUSY hybrid model

description: The large tensor spectrum recently observed by the BICEP2 Collaboration requires a super-Planckian field variation of the inflaton in the single-field inflationary scenario. The required slow-roll parameter ε\approx 0.01 would restrict the e-folding number to around 7 in (sub-)Planckian inflationary models. To overcome such problems, we consider a two-field scenario based on the natural assisted supersymmetric (SUSY) hybrid model ("natural SUSY hybrid inflation" [1]), which combines the SUSY hybrid and the natural inflation models. The axionic inflaton field from the natural inflation sector can admit the right values for the tensor spectrum as well as a spectral index of 0.96 with a decay constant smaller than the Planck scale, f \lesssim M_P. On the other hand, the vacuum energy of 2 x 10^{16} GeV with 50 e-folds is provided by the inflaton coming from the SUSY hybrid sector, avoiding the eta problem. These are achieved by introducing both the U(1)_R and a shift symmetry, and employing the minimal Kahler potential.

description: In the past few years, the Event Horizon Telescope (EHT) has provided the first-ever event horizon-scale images of the supermassive black holes (BHs) (M87*) and Sagittarius A$^*$ (Sgr A*). The next-generation EHT project is an extension of the EHT array that promises larger angular resolution and higher sensitivity to the dim, extended flux around the central ring-like structure, possibly connecting the accretion flow and the jet. The ngEHT Analysis Challenges aim to understand the science extractability from synthetic images and movies to inform the ngEHT array design and analysis algorithm development. In this work, we compare the accretion flow structure and dynamics in numerical fluid simulations that specifically target M87* and Sgr A*, and were used to construct the source models in the challenge set. We consider (1) a steady-state axisymmetric radiatively inefficient accretion flow model with a time-dependent shearing hotspot, (2) two time-dependent single fluid general relativistic magnetohydrodynamic (GRMHD) simulations from the H-AMR code, (3) a two-temperature GRMHD simulation from the BHAC code, and (4) a two-temperature radiative GRMHD simulation from the KORAL code. We find that the different models exhibit remarkably similar temporal and spatial properties, except for the electron temperature, since radiative losses substantially cool down electrons near the BH and the jet sheath, signaling the importance of radiative cooling even for slowly accreting BHs such as M87*. We restrict ourselves to standard torus accretion flows, and leave larger explorations of alternate accretion models to future work.

description: In der vorliegenden Studie wurden die Mathematikschulleistungen von 124 Schülerinnen und Schüler der 5. bis 9. Klasse aus drei Münchner Förderzentren untersucht. Ziel der Studie war es, das mathematische Leistungsspektrum der Schülerinnen und Schüler mit sonderpädagogischem Förderbedarf in der Sekundarstufe zu ermitteln. Das Spektrum der Schülerinnen und Schüler einer Klasse war dabei sehr heterogen. Generell festzustellen ist, dass die mathematischen Basiskompetenzen, also die Mengen-Zahlen-Kompetenzen und das Konventions- und Regelwissen, bei diesen Schülerinnen und Schüler der Sekundarstufe nicht ausreichend gesichert waren. Erwartungsgemäß waren die mathematischen Kompetenzen in den höheren Klassen weiter entwickelt als in den niedrigeren Jahrgangsstufen. Jedoch geben neben der Klassenstufe auch die Einschätzungen der Lehrerinnen und Lehrer bezüglich des Bedarfs nach individueller Unterstützung der Schülerinnen und Schüler sowie des Stands nach dem Regellehrplan der Schülerinnen und Schüler eine signifikante Varianzaufklärung auf die Schulleistung in Mathematik. Dies stellt eine heterogene Schülerschaft in der Sekundarstufe der Förderschulen dar und zeigt, dass eine Klassenbildung nach Schuljahren nicht zu leistungshomogenen Gruppen führt.

Data governance

description: The 1+MG Declaration foresees a harmonised data governance for the genomic data infrastructure, which is applicable to all data included into and used from the 1+MG data infrastructure. Data governance is a central element for the entire design of the 1+MG data infrastructure. It influences the legal implementation as well as the IT infrastructure and the information management, which must reflect and enable the workflows of the data governance. 
In WP2 of the GDI project, we are developing recommendations for such data governance with respect to the data access procedure for scientific research, healthcare reuse, policy development and quality management as well as governance for inclusion of data into 1+MG and for data use. We aim for an agreement between the national representatives on the governance panel on data governance which is pivotal to prepare the implementation. 
This deliverable reports on experience collected from existing national and international data infrastructures with the focus on data access governance. This is based on input gathered in the project HealthData @ EU and complemented by information gathered in a workshop that we organised ourselves. WP2 organised in September 2023 a workshop with representatives from various European data infrastructures for secondary use and 1+MG ELSI Working Group members. 
Before the workshop, participants were queried on practical aspects of data governance for secondary use, also beyond research purposes. The results of this survey allow us to conclude that all currently envisaged purposes for secondary use are relevant to generate value from genomic and health data. Among these purposes, scientific research and policy development purposes can build on a similar data governance on the one hand, and so can healthcare reuse and quality management purposes on the other hand. Budget needs to be foreseen will be needed to set up a Data Access Committee (DAC) with dedicated staff at the genomic data infrastructure, to develop IT tools supporting the data governance workflows as well as to generate and provide clear and harmonised information, materials and procedures to applicants. These upfront investments will allow us to reduce administrative costs later caused by incomplete applications and high needs for direct communications with applicants. Finally, we envisage in principle an open ended retention time for the data, subject to a regular assessment of future usability of the data, to allow the creation of more value from data. The value for future use has to be balanced with capacities, cost and future technical developments.
Natural Inflation: Consistency with Cosmic Microwave Background Observations of Planck and BICEP2

description: Natural inflation is a good fit to all cosmic microwave background (CMB) data and may be the correct description of an early inflationary expansion of the Universe. The large angular scale CMB polarization experiment BICEP2 has announced a major discovery, which can be explained as the gravitational wave signature of inflation, at a level that matches predictions by natural inflation models. The natural inflation (NI) potential is theoretically exceptionally well motivated in that it is naturally flat due to shift symmetries, and in the simplest version takes the form $V(ϕ) = Λ^4 [1 \pm \cos(Nϕ/f)]$. A tensor-to-scalar ratio $r>0.1 $ as seen by BICEP2 requires the height of any inflationary potential to be comparable to the scale of grand unification and the width to be comparable to the Planck scale. The Cosine Natural Inflation model agrees with all cosmic microwave background measurements as long as $f \geq m_{\rm Pl}$ (where $m_{\rm Pl} = 1.22 \times 10^{19}\ {\rm GeV}$) and $Λ\sim m_{\rm GUT} \sim 10^{16}\ {\rm GeV}$. This paper also discusses other variants of the natural inflation paradigm: we show that axion monodromy with potential $V\propto ϕ^{2/3}$ is inconsistent with the BICEP2 limits at the 95\% confidence level, and low-scale inflation is strongly ruled out. Linear potentials $V \propto ϕ$ are inconsistent with the BICEP2 limit at the 95\% confidence level, but are marginally consistent with a joint Planck/BICEP2 limit at 95\%. We discuss the pseudo-Nambu Goldstone model proposed by Kinney and Mahanthappa as a concrete realization of low-scale inflation. While the low-scale limit of the model is inconsistent with the data, the large-field limit of the model is marginally consistent with BICEP2. All of the models considered predict negligible running of the scalar spectral index, and would be ruled out by a detection of running.

description: Based on the effective dynamics in the $\bar μ$ scheme of the spherical symmetry reduced model in the reduced phase space formulation of loop quantum gravity (LQG), we investigate the gravitational collapse of a homogeneous dust cloud, with Gaussian dust serving as both the reference field and the source of the gravitational collapse. The effective dynamics from the considered model for a homogeneous dust cloud reduces precisely to the effective dynamics of loop quantum cosmology (LQC) with extrinsic curvature based K-quantization, indicating that the LQC effective dynamics lives as a subsector of the model presented here. In both the marginally bound and the bound cases of the collapse in effective dynamics, the singularity is resolved and replaced by a bounce. Though quantum geometric modification from spatial curvature is not directly included in the K-quantization it does affect the qualitative dynamics of the collapsing dust cloud in the sense that on the one hand for the marginally bound case, the dust cloud bounces once at fixed maximum energy density and on the other hand for the bound case, the dust cloud undergoes infinite cycles of contraction and expansion at energy densities dependent on the dust mass. Finally, the mass threshold for the formation of a trapped surface in each case is found and the matching conditions between the interior collapsing spacetime and an effective exterior static solution are discussed.

description: Successful inclusive education creates a learning environment that supports not only the cognitive abilities of all children but also their social and emotional development. The present study focuses on the development of social participation of students with and without special education needs (SEN). A longitudinal study with two measurement times was conducted. The first measurement (T1) took place at the end of fifth grade, the second (T2) one year later. The sample consisted of 35 SEN students and108 non-SEN students from mainstream classes in Graz, Austria. For assessing the self-perception of social inclusion, items from the ‘dimensions of integration’ questionnaire (FDI 4–6) were used. Social participation does not seem to be a very stable phenomenon; its retest reliability was only .47 for SEN students and .54 for non-SEN students. Results indicate that children with SEN experienced less social participation than children without SEN at T1 and T2. To identify the predictors for social participation, a multiple regression analysis was conducted. Next to social participation at T1, indirect aggressive behaviour (self-assessed) also appears to predict social participation at T2.

description: We theoretically study energy pumping processes in an electrical circuit with avalanche diodes, where non-Gaussian athermal noise plays a crucial role. We show that a positive amount of energy (work) can be extracted by an external manipulation of the circuit in a cyclic way, even when the system is spatially symmetric. We discuss the properties of the energy pumping process for both quasi-static and fnite-time cases, and analytically obtain formulas for the amounts of the work and the power. Our results demonstrate the significance of the non-Gaussianity in energetics of electrical circuits.

description: Graph-based linear scaling electronic structure theory for quantum-mechanical molecular dynamics simulations is adapted to the most recent shadow potential formulations of extended Lagrangian Born-Oppenheimer molecular dynamics, including fractional molecular-orbital occupation numbers, which enables stable simulations of sensitive complex chemical systems with unsteady charge solutions. The proposed formulation includes a preconditioned Krylov subspace approximation for the integration of the extended electronic degrees of freedom, which requires quantum response calculations for electronic states with fractional occupation numbers. For the response calculations we introduce a graph-based canonical quantum perturbation theory that can be performed with the same natural parallelism and linear scaling complexity as the graph-based electronic structure calculations for the unperturbed ground state. The proposed techniques are particularly well-suited for semi-empirical electronic structure theory and the methods are demonstrated using self-consistent charge density-functional tight-binding (SCC-DFTB) theory, both for the acceleration of self-consistent field calculations and for quantum molecular dynamics simulations. The graph-based techniques combined with the semi-empirical theory enable stable simulations of large, complex chemical systems, including tens-of-thousands of atoms.

description: In inclusive classrooms teamwork and collaboration between general teachers and special education teachers are among the most important factors for student achievement. Yet, to date, little evidence exists on how teacher collaboration is implemented and whether general and special education teachers value their collaboration equally. The current study analyzes teacher collaboration in inclusive classrooms at elementary and secondary school levels. Participants were 191 general teachers and 130 special education teachers. The results suggest that all teachers were satisfi ed with their teamwork; diff erences between general and special education teachers were non-signifi cant. Elementary school teachers had more positive perceptions than secondary school teachers. These fi ndings are discussed in terms of their theoretical signifi cance and their practical relevance for teacher education in inclusive classrooms.

description: We construct boson star configurations in quantum field theory using the semiclassical gravity approximation. Restricting our attention to the static case, we show that the semiclassical Einstein-Klein-Gordon system for a {\it single real quantum} scalar field whose state describes the excitation of $N$ {\it identical particles}, each one corresponding to a given energy level, can be reduced to the Einstein-Klein-Gordon system for $N$ {\it complex classical} scalar fields. Particular consideration is given to the spherically symmetric static scenario, where energy levels are labeled by quantum numbers $n$, $\ell$ and $m$. When all particles are accommodated in the ground state $n=\ell=m=0$, one recovers the standard static boson star solutions, that can be excited if $n\neq 0$. On the other hand, for the case where all particles have fixed radial and total angular momentum numbers $n$ and $\ell$, with $\ell\neq 0$, but are homogeneously distributed with respect to their magnetic number $m$, one obtains the $\ell$-boson stars, whereas when $\ell=m=0$ and $n$ takes multiple values, the multi-state boson star solutions are obtained. Further generalizations of these configurations are presented, including the multi-$\ell$ multi-state boson stars, that constitute the most general solutions to the $N$-particle, static, spherically symmetric, semiclassical real Einstein-Klein-Gordon system, in which the total number of particles is definite. In spite of the fact that the same spacetime configurations also appear in multi-field classical theories, in semiclassical gravity they arise naturally as the quantum fluctuations associated with the state of a single field describing a many-body system. Our results could have potential impact on direct detection experiments in the context of ultralight scalar field/fuzzy dark matter candidates.

description: Any bipartite entanglement witness $W$ can be written as $W=c_σI-σ$, where $σ$ is a quantum state, $I$ is the identity matrix, and $c_σ$ is a non-negative number. We present a general method to extend the given entanglement witness to multipartite cases via purification, partial purification, and direct tensor of the quantum state $σ$. Our methods extend $σ$ but leave the parameter $c_σ$ untouched. This is very valuable since the parameter is generally not easy to compute.

Quantum quench from a thermal tensor state: boundary effects and generalized Gibbs ensemble

description: We consider a quantum quench in a non-interacting fermionic one-dimensional field-theory. The system of size $L$ is initially prepared into two halves $\mathcal{L}$ ($[-L/2,0]$) and $\mathcal{R}$ ($[0,L/2]$), each of them thermalized at two different temperatures, ${T_{L}}$ and ${T_{R}}$ respectively. At a given time the two halves are joined together by a local coupling and the whole system is left to evolve unitarily. For an infinitely extended system ($L\rightarrow \infty$), we show that the time evolution of the particle and energy densities is well described via a hydrodynamic approach which allows us to evaluate the correspondent stationary currents. We show, in such a case, that the two-point correlation functions are deduced, at large times, from a simple non-equilibrium steady state. Otherwise, whenever the boundary conditions are retained (in a properly defined thermodynamic limit), any current is suppressed at large times, and the stationary state is described by a generalized Gibbs ensemble, which is diagonal and depends only on the post-quench mode occupation.

description: The affine oriented Brauer category is a monoidal category obtained from the oriented Brauer category (= the free symmetric monoidal category generated by a single object and its dual) by adjoining a polynomial generator subject to appropriate relations. In this article, we prove a basis theorem for the morphism spaces in this category, as well as for all of its cyclotomic quotients.

description: We present a UV spectroscopic study of ionized outflows in 21 active galactic nuclei (AGN), observed with the HST. The targets of the SUBWAYS sample were selected with the aim to probe the parameter space of the underexplored AGN between the local Seyfert galaxies and the luminous quasars at high redshifts. Our targets, spanning redshifts of 0.1-0.4 and bolometric luminosities (L_bol) of 10^45-10^46 erg/s, have been observed with a large multi-wavelength campaign. Here, we model the UV spectra and look for different types of AGN outflows. We find that 60% of our targets show a presence of outflowing H I absorption, while 40% exhibit ionized outflows seen as absorption by either C IV, N V, or O VI. This is comparable to the occurrence of ionized outflows seen in the local Seyfert galaxies. All UV absorption lines in the sample are relatively narrow, with outflow velocities reaching up to -3300 km/s. We did not detect any UV counterparts to the X-ray ultra-fast outflows (UFOs), most likely due to their being too highly ionized. However, all SUBWAYS targets with an X-ray UFO demonstrate the presence of UV outflows at lower velocities. We find significant correlations between the column density (N) of the UV ions and L_bol of the AGN, with N of H I decreasing with L_bol, while N of O VI is increasing with L_bol. This is likely to be a photoionization effect, where toward higher AGN luminosities, the wind becomes more ionized, resulting in less absorption by neutral or low-ionization ions and more absorption by high-ionization ions. In addition, we find that N of the UV ions decreases as their outflow velocity increases. This may be explained by a mechanical power that is evacuating the UV-absorbing medium. Our observed relations are consistent with multiphase AGN feeding and feedback simulations indicating that a combination of both radiative and mechanical processes are in play.

description: In a previous paper, some of us studied general relativistic homogeneous gravitational collapses for dust and radiation, in which the density profile was replaced by an effective density justified by some quantum gravity models. It was found that the effective density introduces an effective pressure that becomes negative and dominant in the strong-field regime. With this set-up, the central singularity is replaced by a bounce, after which the cloud starts expanding. Motivated by the fact that in the classical case homogeneous and inhomogeneous collapse models have different properties, here we extend our previous work to the inhomogeneous case. As in the quantum-inspired homogeneous collapse model, the classical central singularity is replaced by a bounce, but the inhomogeneities strongly affect the structure of the bounce curve and of the trapped region.

description: The Darboux-Egoroff system of PDEs with any number $n\ge 3$ of independent variables plays an essential role in the problems of describing $n$-dimensional flat diagonal metrics of Egoroff type and Frobenius manifolds. We construct a recursion operator and its inverse for symmetries of the Darboux-Egoroff system and describe some symmetries generated by these operators. The constructed recursion operators are not pseudodifferential, but are Backlund autotransformations for the linearized system whose solutions correspond to symmetries of the Darboux-Egoroff system. For some other PDEs, recursion operators of similar types were considered previously by Papachristou, Guthrie, Marvan, Poboril, and Sergyeyev. In the structure of the obtained third and fifth order symmetries of the Darboux-Egoroff system, one finds the third and fifth order flows of an $(n-1)$-component vector modified KdV hierarchy. The constructed recursion operators generate also an infinite number of nonlocal symmetries. In particular, we obtain a simple construction of nonlocal symmetries that were studied by Buryak and Shadrin in the context of the infinitesimal version of the Givental-van de Leur twisted loop group action on the space of semisimple Frobenius manifolds. We obtain these results by means of rather general methods, using only the zero-curvature representation of the considered PDEs.
