description: Galaxies are not distributed randomly in the cosmic web but are instead arranged in filaments and sheets surrounding cosmic voids. Observationally there is still no convincing evidence of a link between the properties of galaxies and their host structures. However, by the tidal torque theory (our understanding of the origin of galaxy angular momentum), such a link should exist. Using the presently largest spectroscopic galaxy redshift survey (SDSS) we study the connection between the spin axes of galaxies and the orientation of their host filaments. We use a three dimensional field of orientations to describe cosmic filaments. To restore the inclination angles of galaxies, we use a 3D photometric model of galaxies that gives these angles more accurately than traditional 2D models. We found evidence that the spin axes of bright spiral galaxies have a weak tendency to be aligned parallel to filaments. For elliptical/S0 galaxies, we have a statistically significant result that their spin axes are aligned preferentially perpendicular to the host filaments; we show that this signal practically does not depend on the accuracy of the estimated inclination angles for elliptical/S0 galaxies.

description: We show that metamaterials can be used as a testing ground to investigate spontaneous symmetry breaking associated with non-Hermitian quantum systems. By exploring the interplay between near-field dipolar coupling and material absorption or gain, we demonstrate various spontaneous breaking processes of the $\mathcal{PT}$-symmetry for a series of effective Hamiltonians associated to the scattering matrix. By tuning the coupling parameter, coherent perfect absorption, laser action and gain-induced complete reflection ($π$ reflector) by using an ultra-thin metamaterial can be obtained. Moreover, an ideal $\mathcal{PT}$-symmetry can be established effectively in a passive system by exploring the balance between scattering and absorption loss using metamaterials.

description: We study the formation of superradiant bound states for massive scalar fields in five-dimensional rotating black string geometries with a non-vanishing Kaluza-Klein momentum along the compact direction. Even though all Kaluza-Klein modes may form bound states in this geometry, in realistic extra-dimensional models and astrophysical black holes only the zero-mode is sufficiently light for superradiant instabilities to develop, provided the field has a small but non-vanishing mass, as for example for axion-like particles. We use analytical and numerical methods to show that, although the Kaluza-Klein momentum decreases the upper bound on the field mass for an instability to develop, it may enhance its maximum growth rate by more than 50%, thus boosting the black hole bomb mechanism. We discuss the possible observational consequences of this result and its potential as an astrophysical probe of non-trivial extra-dimensional compactifications.

description: Coalition Structure Generation (CSG) is an NP-Hard problem in which agents are partitioned into mutually exclusive groups to maximize their social welfare. In this work, we propose QuACS, a novel hybrid quantum classical algorithm for Coalition Structure Generation in Induced Subgraph Games (ISGs). Starting from a coalition structure where all the agents belong to a single coalition, QuACS recursively identifies the optimal partition into two disjoint subsets. This problem is reformulated as a QUBO and then solved using QAOA. Given an $n$-agent ISG, we show that the proposed algorithm outperforms existing approximate classical solvers with a runtime of $\mathcal{O}(n^2)$ and an expected approximation ratio of $92\%$. Furthermore, it requires a significantly lower number of qubits and allows experiments on medium-sized problems compared to existing quantum solutions. To show the effectiveness of QuACS we perform experiments on standard benchmark datasets using quantum simulation.

description: We propose a simple model for a binary decision making process on a graph, motivated by modeling social decision making with cooperative individuals. The model is similar to a random field Ising model or fiber bundle model, but with key differences on heterogeneous networks. For many types of disorder and interactions between the nodes, we predict discontinuous phase transitions with mean field theory which are largely independent of network structure. We show how these phase transitions can also be understood by studying microscopic avalanches, and describe how network structure enhances fluctuations in the distribution of avalanches. We suggest theoretically the existence of a "glassy" spectrum of equilibria associated with a typical phase, even on infinite graphs, so long as the first moment of the degree distribution is finite. This behavior implies that the model is robust against noise below a certain scale, and also that phase transitions can switch from discontinuous to continuous on networks with too few edges. Numerical simulations suggest that our theory is accurate.

description: Recent works have validated the possibility of improving energy efficiency in radio access networks (RANs), achieved by dynamically turning on/off some base stations (BSs). In this paper, we extend the research over BS switching operations, which should match up with traffic load variations. Instead of depending on the dynamic traffic loads which are still quite challenging to precisely forecast, we firstly formulate the traffic variations as a Markov decision process. Afterwards, in order to foresightedly minimize the energy consumption of RANs, we design a reinforcement learning framework based BS switching operation scheme. Furthermore, to avoid the underlying curse of dimensionality in reinforcement learning, a transfer actor-critic algorithm (TACT), which utilizes the transferred learning expertise in historical periods or neighboring regions, is proposed and provably converges. In the end, we evaluate our proposed scheme by extensive simulations under various practical configurations and show that the proposed TACT algorithm contributes to a performance jumpstart and demonstrates the feasibility of significant energy efficiency improvement at the expense of tolerable delay performance.

description: The effects of spatial confinements and smooth cutoffs of the waiting time distribution in continuous-time random walks (CTRWs) are studied analytically. We also investigate dependences of ergodic properties on initial ensembles (i.e., distributions of the first waiting time). Here, we consider two ensembles: the equilibrium and a typical non-equilibrium ensembles. For both ensembles, it is shown that the time-averaged mean square displacement (TAMSD) exhibits a crossover from normal to anomalous diffusion due to the spacial confinement and this crossover does not vanish even in the long measurement time limit. Moreover, for the non-equilibrium ensemble, we show that the probability density function of the diffusion constant of TAMSD follows the transient Mittag-Leffler distribution, and that scatter in the TAMSD shows a clear transition from weak ergodicity breaking (an irreproducible regime) to ordinary ergodic behavior (a reproducible regime) as the measurement time increases. This convergence to ordinary ergodicity requires a long measurement time compared to common distributions such as the exponential distribution; in other words, the weak ergodicity breaking persists for a long time. In addition, it is shown that, besides the TAMSD, a class of observables also exhibits this slow convergence to ergodicity. We also point out that, even though the system with the equilibrium initial ensemble shows no aging, its behavior is quite similar to that for the non-equilibrium ensemble.

description: The ATLAS and CMS experiments did not find evidence for Supersymmetry using close to 5/fb of published LHC data at a center-of-mass energy of 7 TeV. We combine these LHC data with data on B_s -> mu mu (LHCb experiment), the relic density (WMAP and other cosmological data) and upper limits on the dark matter scattering cross sections on nuclei (XENON100 data). The excluded regions in the constrained Minimal Supersymmetric SM (CMSSM) lead to gluinos excluded below 1270 GeV and dark matter candidates below 220 GeV for values of the scalar masses (m_0) below 1500 GeV. For large m_0 values the limits of the gluinos and the dark matter candidate are reduced to 970 GeV and 130 GeV, respectively. If a Higgs mass of 125 GeV is imposed in the fit, the preferred SUSY region is above this excluded region, but the size of the preferred region is strongly dependent on the assumed theoretical error.

description: The state of a system in classical mechanics can be uniquely reconstructed if we know the positions and the momenta of all its parts. In 1958 Pauli has conjectured that the same holds for quantum mechanical systems. The conjecture turned out to be wrong. In this paper we provide a new set of examples of Pauli pairs, being the pairs of quantum states indistinguishable by measuring the spatial location and momentum. In particular, we construct a new set of spatially localized Pauli pairs.

description: We compare two different models of transport of light in a disordered system with a spherical Gaussian distribution of scatterers. A coupled dipole model, keeping into account all interference effects, is compared to an incoherent model, using a random walk of particles. Besides the well known coherent backscattering effect and a well pronounced forward lobe, the incoherent model reproduces extremely well all scattering features. In an experiment with cold atoms, we use the momentum recoil imparted on the center of mass of the sample as a partial probe of the light scattering properties. We find that the force acting on the center of mass of the atoms is not well suited to exhibit the coherence effects in light propagation under multiple scattering conditions.

description: Die chronologische Bewertung des archäologischen Untersuchungsmaterials sowie dessen Deutung gehen eine enge Symbiose ein. Ihr Bindeglied ist das europäische Entwicklungsdenken. Dessen verbreitete Akzeptanz macht archäologische Forschung in seiner heutigen Ausprägung erst möglich. Wegbereiter dieser Form des Zeitverstehens waren geologische, paläontologische und ethnografische Feldbeobachtungen. Insbesondere das ethnografische Präsens wurde auf die menschliche Vor- und Frühgeschichte ausgedehnt. So entstand das Bild der kulturellen Statik der Steinzeit und der sich zur Gegenwart hin beschleunigenden Geschichte. Dieser Gegensatz resultiert letztlich aus der Verschmelzung der Plausibilitäten ‚unserer‘ kulturellen Eigenzeit mit der der wissenschaftlichen Beobachtungssituation. Die eigenen Zeitkonventionen wirken sich auf den fachlichen Umgang mit kultur- und naturwissenschaftlichen Datierungen und Chronologiesystemen aus. Sie führen zu der hier untersuchten inhaltlichen Unbestimmtheit des archäologischen Deutens.
Vergleichbares gilt auch für den Umgang mit dem archäologischen Quellenmaterial. Hier ist auf zwei Ebenen eine wissenschaftliche Unbestimmtheit zu konstatieren. Einerseits ist es die chronologische Unschärfe, andererseits beinhaltet das Untersuchungsobjekt (Befunde und Funde) selbst in sich verschiedene Zeitdimensionen. Diese werden im Rahmen der archäologischen Forschung als objektcharakterisierende Eigenschaften erfasst. Hinzu kommen noch weitere Einflussfaktoren, die ebenfalls zur Unbestimmtheit wissenschaftlicher Aussagen beitragen. Im Rahmen dieses Beitrags werden die Auswirkungen dieser Einflussfaktoren auf den archäologischen Umgang mit Zeit hinterfragt.

description: Wissenschaftlich Neues und gesellschaftlicher Wandel wechselwirken. Die Gegenwart um 1800 verändert Temporalstrukturen ebenso spezifisch wie sie als neue Zeitstruktur selbst die Bildung wissenschaftlicher Erkenntnis erst hervorbringt. Die Zeitgestaltung der sich industrialisierenden Jahrzehnte um 1800 verzeitlicht alle Daseinsbereiche auf neue Weise. Gerade mehr Materialität, die Vervielfältigung und Beschleunigung von Dingen, bringt dabei neue Zeitstrukturen hervor. Das hat auch Auswirkungen auf die archäologische Forschung: Denn in diesen temporalen Konstellationen bildet die Archäologie methodologische Grundmuster, mit denen sie fortan ihre Logik systemisch formen sollte, ausgehend von ihrem nun zeitorientierten Gegenstand, dem Materialen – der dinglichen Welt vergangener Kulturen.
Der vorliegende Essay untersucht genau diese zeitgeistbedingte Archäologisierung. Denn gerade die allgemeine temporale Spezifik dieses neuen, stets wachsenden Mehr an Dingen markiert eine der massivsten (im Wortsinne) Veränderungen der Archäologie überhaupt, indem sie die Herausbildung einer ihrer ersten kanonischen Methoden bewirkte, welche systemisch die Archäologie verfachlichte. Dabei entstanden Vorstellungen wie ‚die Bronzezeit’, die als Imaginationen die älteste Geschichte rationalisierten, denn: Der neue Umgang mit den rasant mehr werdenden Objekten des Altertums bedingt nach 1800 die Zeitlichkeit des neuen dingorientierten Arguments und die Anfänge Archäologischer Zeit in dieser weltbildwandelnden Gegenwart – auch sie wechselwirken. Das zeige ich entlang des Konzeptes Steinzeit–Bronzezeit–Eisenzeit auf, einem Resultat der archäologischen Verzeitlichung der neuen temporalen Möglichkeiten der Jahrzehnte um 1800 und dinglicher Ausdruck neuen Denkens gleichwie Fundierung der ‚Archäologik’.

description: Random neural networks are dynamical descriptions of randomly interconnected neural units. These show a phase transition to chaos as a disorder parameter is increased. The microscopic mechanisms underlying this phase transition are unknown, and similarly to spin-glasses, shall be fundamentally related to the behavior of the system. In this Letter we investigate the explosion of complexity arising near that phase transition. We show that the mean number of equilibria undergoes a sharp transition from one equilibrium to a very large number scaling exponentially with the dimension on the system. Near criticality, we compute the exponential rate of divergence, called topological complexity. Strikingly, we show that it behaves exactly as the maximal Lyapunov exponent, a classical measure of dynamical complexity. This relationship unravels a microscopic mechanism leading to chaos which we further demonstrate on a simpler class of disordered systems, suggesting a deep and underexplored link between topological and dynamical complexity.

Efforts have been made to align school architecture with therecent trends in education and support the learning process with appropriate and stimulating environments.This study analyzed Evidence Based Design (EBD) information related to school buildings with particularattention to middle schools through a Systematic Literature Review (SLR). Gained knowledge was transformedinto architectural design patterns and their graphical representations. This research's product is a tool tosupport the school design process through patterns tested with architecture course students. The research ispart of a continuous investigation of design methods and contemporary school architecture. The collection andorganization of new knowledge should positively support the design process with scientific information,translated into an insightful and clear textual and graphical language to stimulate the design of school buildingsappropriate to their context and create a positive and productive learning environment.

description: Natürliche zyklische Vorgänge, d.h. astronomische Zyklen wie der Sonnentag, der Mondmonat oder das Sonnenjahr oder physiologische Zyklen wie der circadiane Rhythmus oder der Menstruationszyklus, werden oft verwendet, um in archäologischen Funden und Befunden eingebettete Zeitinformation aufzudecken. Die Deutung bestimmter prähistorischer Artefakte als Kalendarien stellt hierfür ein wichtiges Beispiel dar. Neben einer Bevorzugung physiologischer Rhythmen als Analogien für das Paläo- und Neolithikum und astronomischer Rhythmen für die Bronzezeit fällt auf, daß in der Archäologie oft nur nach auffallenden Zahlen wie 29 oder 30 gesucht wird, ohne Hinweise für die Wiederkehr dieser Zählungen in den Artefakten zu liefern. Siedlungsstratigraphien, das zweite Beispiel, können ebenfalls als Resultate zugrundeliegender natürlicher Zyklen wie dem Jahr, Generationenwechseln oder Regenerationszyklen von Bauholz gedeutet werden. Während Ansätze, die nur die reine Tiefe der Ablagerungen heranziehen, sehr unzuverlässig sind, erlauben wiederholte Ablagerungen ähnlicher Befunde wie Fußböden oder Häuser mit bekannter Zeitdauer die Interpretation von Stratigraphien in Analogie zu natürlichen Rhythmit-Sedimenten wie den Warven. In beiden Beispielen muß jedoch beachtet werden, daß alle Zeiteinheiten wie der Monat oder das Landwirtschaftsjahr menschliche Konstrukte sind, die an die natürlichen Zyklen nur angelehnt sind, und daß auch völlig künstliche Zyklen wie die Woche existieren.

description: The flux and nuclear composition of ultra-high energy cosmic rays depend on the cosmic distribution of their sources. Data from cosmic ray observatories are yet inconclusive about their exact location or distribution, but provide a measure for the average local density of these emitters. Due to the discreteness of the emitters the flux and nuclear composition is expected to show ensemble fluctuations on top of the statistical variations, i.e. "cosmic variance". This effect is strongest for the most energetic cosmic rays due to the limited propagation distance in the cosmic radiation background and is hence a local phenomenon. For the statistical analysis of cosmic ray emission models it is important to quantify the possible level of this variance. In this paper we present a completely analytic method that describes the variation of the flux and nuclear composition with respect to the local source density. We highlight that proposed future space-based observatories with exposures of O(10^6 km^2 sr yr) will attain sensitivity to observe these spectral fluctuations in the cosmic ray energy spectrum at Earth relative to the overall power-law fit.

description: 1. Baited remote underwater stereo-video systems (stereo-BRUVs) are a popular tool to sample demersal fish assemblages and gather data on their relative abundance and body size structure in a robust, cost-effective and non-invasive manner. Given the rapid uptake of the method, subtle differences have emerged in the way stereo-BRUVs are deployed and how the resulting imagery is annotated. These disparities limit the interoperability of datasets obtained across studies, preventing broadscale insights into the dynamics of ecological systems. 2. We provide the first globally accepted guide for using stereo-BRUVs to survey demersal fish assemblages and associated benthic habitats. 3. Information on stereo-BRUVs design, camera settings, field operations and image annotation are outlined. Additionally, we provide links to protocols for data validation, archiving and sharing. 4. Globally, the use of stereo-BRUVs is spreading rapidly. We provide a standardized protocol that will reduce methodological variation among researchers and encourage the use of Findable, Accessible, Interoperable and Reusable workflows to increase the ability to synthesize global datasets and answer a broad suite of ecological questions.

description: We study particle generation by a strong electric field in lattice QCD. To avoid the sign problem of the Minkowskian electric field, we adopt the "isospin" electric charge. When a strong electric field is applied, the insulating vacuum is broken down and pairs of charged particles are produced by the Schwinger mechanism. The competition against the color confining force is also discussed.

description: The violation of a classical Cauchy-Schwarz (CS) inequality is identified as an unequivocal signature of spontaneous Hawking radiation in sonic black holes. This violation can be particularly large near the peaks in the radiation spectrum emitted from a resonant boson structure forming a sonic horizon. As a function of the frequency-dependent Hawking radiation intensity, we analyze the degree of CS violation and the maximum violation temperature for a double barrier structure separating two regions of subsonic and supersonic condensate flow. We also consider the case where the resonant sonic horizon is produced by a space-dependent contact interaction. In some cases, CS violation can be observed by direct atom counting in a time-of-flight experiment. We show that near the conventional zero-frequency radiation peak, the decisive CS violation cannot occur.

description: NGC 5291, an early-type galaxy surrounded by a giant HI ring, is believed to be formed from collision with another galaxy. Several star forming complexes and tidal dwarf galaxies are distributed along the collisional ring which are sites of star formation in environments where extreme dynamical effects are involved. Dynamical effects can affect the star formation properties and the spatial distribution of star forming complexes along the tidal features. To study and quantify the star formation activity in the main body and in the ring structure of the NGC 5291 system, we use high spatial resolution FUV and NUV imaging observations from the Ultraviolet Imaging Telescope onboard AstroSat. A total of 57 star-forming knots are identified to be part of this interacting system out of which 12 are new detections (star forming complexes that lie inside the HI contour) compared to the previous measurements from lower resolution UV imaging. We estimate the attenuation in UV for each of the resolved star-forming knots using the UV spectral slope $β$, derived from the FUV-NUV colour. Using the extinction corrected UV fluxes, we derive the star formation rate of the resolved star forming complexes. The extinction corrected total star formation rate of this system is estimated as 1.75 $\pm$ 0.04 $M_{\odot}/yr$. The comparison with dwarf galaxy populations (BCD, Sm and dIm galaxies) in the nearby Universe shows that many of the knots in the NGC 5291 system have SFR values comparable to the SFR of BCD galaxies.

description: We study the Cauchy problem for the Gross-Pitaevskii equation with a nonlocal interaction potential of Hartree type in three space dimensions. If the potential is even and positive definite or a positive function and its Fourier transform decays sufficiently rapidly the problem is shown to be globally well-posed for large rough data which not necessarily have finite energy and also in a situation where the energy functional is not positive definite. The proof uses a suitable modification of the I-method.

description: We carry out an analysis of a set of cosmological SPH hydrodynamical simulations of galaxy clusters and groups aimed at studying the total baryon budget in clusters, and how this budget is shared between the hot diffuse component and the stellar component. Using the TreePM+SPH GADGET-3 code, we carried out one set of non-radiative simulations, and two sets of simulations including radiative cooling, star formation and feedback from supernovae (SN), one of which also accounting for the effect of feedback from active galactic nuclei (AGN). The analysis is carried out with the twofold aim of studying the implication of stellar and hot gas content on the relative role played by SN and AGN feedback, and to calibrate the cluster baryon fraction and its evolution as a cosmological tool. We find that both radiative simulation sets predict a trend of stellar mass fraction with cluster mass that tends to be weaker than the observed one. However this tension depends on the particular set of observational data considered. Including the effect of AGN feedback alleviates this tension on the stellar mass and predicts values of the hot gas mass fraction and total baryon fraction to be in closer agreement with observational results. We further compute the ratio between the cluster baryon content and the cosmic baryon fraction, Y_b, as a function of cluster-centric radius and redshift. At R_500 we find for massive clusters with M_500>2\times10^{14} h^{-1} M_sun that Y_b is nearly independent of the physical processes included and characterized by a negligible redshift evolution: Y_{b,500}=0.85+/-0.03 with the error accounting for the intrinsic r.m.s. scatter within the set of simulated clusters. At smaller radii, R_2500, the typical value of Y_b slightly decreases, by an amount that depends on the physics included in the simulations, while its scatter increases by about a factor of two.

description: We investigate the photoionization spectrum of helium by attosecond XUV pulses both in the spectral region of doubly excited resonances as well as above the double ionization threshold. In order to probe for convergence, we compare three techniques to extract photoelectron spectra from the wavepacket resulting from the integration of the time-dependent Schroedinger equation in a finite-element discrete variable representation basis. These techniques are: projection on products of hydrogenic bound and continuum states, projection onto multi-channel scattering states computed in a B-spline close-coupling basis, and a technique based on exterior complex scaling (ECS) implemented in the same basis used for the time propagation. These methods allow to monitor the population of continuum states in wavepackets created with ultrashort pulses in different regimes. Applications include photo cross sections and anisotropy parameters in the spectral region of doubly excited resonances, time-resolved photoexcitation of autoionizing resonances in an attosecond pump-probe setting, and the energy and angular distribution of correlated wavepackets for two-photon double ionization.

description: A semi-analytical approach to atomic waveguide scattering for harmonic confinement is developed taking into account all partial waves. As a consequence $\ell$-wave confinement-induced resonances are formed being coupled to each other due to the confinement. The corresponding resonance condition is obtained analytically using the $K$-matrix formalism. Atomic scattering is described by transition diagrams which depict all relevant processes the atoms undergo during the collision. Our analytical results are compared to corresponding numerical data and show very good agreement.
