description: We study the critical current I_c dependence on applied magnetic field H for multifacet YBa_2Cu_3O_{7-δ}-Au-Nb ramp-type zigzag Josephson junctions. For many experiments one would like to apply a homogeneous field in the junction plane. However, even tiny misalignments can cause drastic deviations from homogeneity. We show this explicitly by measuring and analyzing I_c vs. H for an 8 facet junction, forming an array of 4\times(0-π)-segments. The ramp angle is θ_r=8^\circ. The facet width is 10\,\mum. H is applied under different angles θrelative to the substrate plane and different angles ϕrelative to the in-plane orientation of the zigzags. We find that a homogeneous flux distribution is only achieved for an angle θ_h\approx 1^\circ - 2^\circ and that even a small misalignment \sim 0.1^\circ relative to θ_h can cause a substantial inhomogeneity of the flux density inside the junction, drastically altering its I_c vs. H interference pattern. We also show, that there is a dead angle θ^*_d relative to θ_h of similar magnitude, where the average flux density completely vanishes.

description: Phase transitions in equilibrium and nonequilibrium systems play a major role in the natural sciences. In dynamical networks, phase transitions organize qualitative changes in the collective behavior of coupled dynamical units. Adaptive dynamical networks feature a connectivity structure that changes over time, coevolving with the nodes’ dynamical state. In this Letter, we show the emergence of two distinct first-order nonequilibrium phase transitions in a finite-size adaptive network of heterogeneous phase oscillators. Depending on the nature of defects in the internal frequency distribution, we observe either an abrupt single-step transition to full synchronization or a more gradual multistep transition. This observation has a striking resemblance to heterogeneous nucleation. We develop a mean-field approach to study the interplay between adaptivity and nodal heterogeneity and describe the dynamics of multicluster states and their role in determining the character of the phase transition. Our work provides a theoretical framework for studying the interplay between adaptivity and nodal heterogeneity.

description: In the previous paper we examined the third quantization of the $f(R)$-type gravity and studied the Heisenberg uncertainty relation of the universe in the example of $f(R)=R^2$. In this work the Heisenberg uncertainty relation of the universe is investigated in the general $f(R)$-type gravity where tachyonic states are avoided. It is shown that, at late times namely the scale factor of the universe is large, the spacetime becomes classical, and, at early times namely the scale factor of the universe is small, the quantum effects dominate.

description: Cr-N codoping approach is studied using both cluster-assembled and epitaxial TiO2 films. simultaneously injecting the two atomic species substantially modifies the TiO2 band gap, reducing it by more than 1 eV. XPS, XAS and optical spectroscopy characterizations confirm that the atoms are succesfully embedded inside the system and that the band gap is reduced. Cr-N coupling is confirmed in the case of epitaxial codoped Titania films.

 Anacroneuria galba Jewett, 1960b: 3; Illies, 1966: 317; Froehlich, 2010: 156.
 Material examined (picture). BR, GO. Paratype: Formoso, 26.v.1956, F.S. T., 1 male (NHM).
 Remarks. The species was described by Jewett (1960b) based on specimens from the region of Formoso, in the north of Goiás state, BR. Similarly to A. dourada, according to the original description the type series is deposited in the National Museum of Rio de Janeiro, RJ, BR (holotype) and NHM, CA, USA (paratypes). However, the holotype is also currently lost. Fortunately, a dry preserved paratype is located in the NHM. The male paratype is well preserved. Its genitalia has not been dissected and there are no illustrations of the penial armature of the species. Therefore, the morphology of this paratype, including the morphology of the penial armature, needs to be carefully studied before trying to associate it with specimens collected in the type locality in north of Goiás state. The fact that the paratype is male can facilitate this process. The other specimens of A. galba cited by Jewett (1960b) for other localities (Espírito Santo, Minas Gerais, and São Paulo states) probably belong to other species (Froehlich 2010).

Quantum graphs with two-particle contact interactions

Year: 2012
Subjects: subject: Mathematical Physics (math-ph)

description: We construct models of many-particle quantum graphs with singular two-particle contact interactions, which can be either hardcore- or delta-interactions. Self-adjoint realisations of the two-particle Laplacian including such interactions are obtained via their associated quadratic forms. We prove discreteness of spectra as well as Weyl laws for the asymptotic eigenvalue counts. These constructions are first performed for two distinguishable particles and then for two identicle bosons. Furthermore, we extend the models to N bosons with two-particle interactions, thus implementing the Lieb-Liniger model on a graph.

description: The goal of the present study is to establish the physical origin of dust heating and emission based on radiation transfer models, which self-consistently connect the emission components from diffuse dust and the dust in massive star forming regions. NGC 4214 is a nearby dwarf galaxy with a large set of ancillary data, ranging from the ultraviolet (UV) to radio, including maps from SPITZER, HERSCHEL and detections from PLANCK. We mapped this galaxy with MAMBO at 1.2 mm at the IRAM 30 m telescope. We extract separate dust emission components for the HII regions (plus their associated PDRs on pc scales) and for the diffuse dust (on kpc scales). We analyse the full UV to FIR/submm SED of the galaxy using a radiation transfer model which self-consistently treats the dust emission from diffuse and SF complexes components, considering the illumination of diffuse dust both by the distributed stellar populations, and by escaping light from the HII regions. While maintaining consistency with the framework of this model we additionally use a model that provides a detailed description of the dust emission from the HII regions and their surrounding PDRs on pc scales. Due to the large amount of available data and previous studies for NGC 4214 very few free parameters remained in the model fitting process. We achieve a satisfactory fit for the emission from HII+PDR regions on pc scales, with the exception of the emission at 8\mi, which is underpredicted by the model. For the diffuse emission we achieve a good fit if we assume that about 30-70% of the emission escaping the HII+PDR regions is able to leave the galaxy without passing through a diffuse ISM, which is not an unlikely scenario for a dwarf galaxy which has recently undergone a nuclear starburst. We determine a dust-to-gas mass ratio of 350-390 which is close to the expected value based on the metallicity.

description: The Technologies for African Agricultural Transformation (TAAT) is a program initiated by the African Development Bank (AfDB) as part of its Feed Africa Initiative. The main objective of the program is to improve the business of agriculture across Africa by raising agricultural productivity, mitigating risks, and promoting diversification and processing in 18 agricultural value chains within eight Priority Intervention Areas (PIA). The program is implemented by International Institute for Tropical Agriculture (IITA) in close partnership with other CGIAR Centers and specialized technical centers (e.g. AATF, IFDC), FARA, national agricultural research, and extension systems, and private sector partners.

 This document presents the results of MEL case study of two technology interventions supported by the Small Livestock Compact of the African Development Bank's (AfDB) Technologies for African Agricultural Transformation (TAAT) program. The first is the sheep fattening program in partnership with the International Center for Agricultural Research in the Dry Areas (ICARDA). The project was implemented in collaboration with ICARDA led Community-Based Breeding Program (CCBP) in Bonga and Doyogena, Southern Nations Nationalities and Peoples Region (SNNPR) and in Menz, Amhara region of Ethiopia. The second intervention was aimed at incorporating forage production into soil and water conservation structures, and to erosion control for improved fodder production, enhanced feed availability and improving livelihood. This project was implemented in Ethiopia's highlands through a partnership with Inter-Aide.
Gauge and matter fields as surfaces and loops - an exploratory lattice study of the Z(3) Gauge-Higgs model

description: We discuss a representation of the Z(3) Gauge-Higgs lattice field theory at finite density in terms of dual variables, i.e., loops of flux and surfaces. In the dual representation the complex action problem of the conventional formulation is resolved and Monte Carlo simulations at arbitrary chemical potential become possible. A suitable algorithm based on plaquette occupation numbers and link-fluxes is introduced and we analyze the model at zero temperature and finite density both in the weak and strong coupling phases. We show that at zero temperature the model has different first order phase transitions as a function of the chemical potential both for the weak and strong coupling phases. The exploratory study demonstrates that alternative degrees of freedom may successfully be used for Monte Carlo simulations in several systems with gauge and matter fields.

EVOLUTION OF PROTEIN INTERACTION NETWORKS THROUGH GENE DUPLICATION
Creators: name: D'ANTONIO, MATTEO
Publisher: name: Universit� degli Studi di Milano
Year: 2011

description: Recent studies on S. cerevisiae showed that essential genes, genes coding for protein complexes and network hubs are singleton, i.e. their duplications are negatively selected. These genes are intrinsically fragile toward perturbations, since dosage modifications yield to alterations in protein function, causing phenotypic aberrations that may affect the whole cell function. Unlike yeast, mammalian duplicated genes mostly encode highly connected proteins, while essentiality is not correlated with duplicability. This difference suggests that dosage-sensitive genes could duplicate at a certain point in evolution, likely favoring the progressive increase in genomic complexity. To understand when and how gene duplicability changed in evolution, we compared gene and network properties in several species from bacteria to primates. The origin and conservation of a gene significantly correlates with the properties of the encoded protein in the protein interaction network. All networks preserve a core of singleton and central hubs that originated early in evolution, are highly conserved, and accomplish basic biological functions. Another group of hubs appeared in metazoans and duplicated in vertebrates, mostly through vertebrate-specific whole genome duplication. Such hubs are frequently target of microRNAs and show tissue-selective expression, suggesting that these are alternative mechanisms to control their dosage. Our study shows how networks modified during evolution and contributes to explain the occurrence of somatic genetic diseases, such as cancer, in terms of network perturbations. Determining the evolutionary characteristics of cancer genes and their position inside the protein interaction network helps understanding the importance of these properties in tumorigenesis.

description: The possible existence of short-range forces between unpolarized and polarized spin-1/2 particles has attracted the attention of physicists for decades. These forces are predicted in various theories and provide a possible new source for parity (P) and time reversal (T) symmetry violation. We use an ensemble of polarized 3He gas in a cell with a 250 um thickness glass window to search for a force from scalar boson exchange over a sub-millimeter ranges. This interaction would produce a NMR frequency shift as an unpolarized mass is moved near and far from the polarized ensemble. We report a new upper bound on the product g_{s}g_{p}^{n} of the scalar couplings to the fermions in the unpolarized mass, and the pseudoscalar coupling of the polarized neutron in the 3He nucleus for force ranges from 1e-4 to 1e-2 m, which corresponds to a mass range of 2e-3 to 2e-5 eV for the scalar boson.

description: Inspired by the legacy of the Netflix contest, we provide an overview of what has been learned---from our own efforts, and those of others---concerning the problems of collaborative filtering and recommender systems. The data set consists of about 100 million movie ratings (from 1 to 5 stars) involving some 480 thousand users and some 18 thousand movies; the associated ratings matrix is about 99% sparse. The goal is to predict ratings that users will give to movies; systems which can do this accurately have significant commercial applications, particularly on the world wide web. We discuss, in some detail, approaches to "baseline" modeling, singular value decomposition (SVD), as well as kNN (nearest neighbor) and neural network models; temporal effects, cross-validation issues, ensemble methods and other considerations are discussed as well. We compare existing models in a search for new models, and also discuss the mission-critical issues of penalization and parameter shrinkage which arise when the dimensions of a parameter space reaches into the millions. Although much work on such problems has been carried out by the computer science and machine learning communities, our goal here is to address a statistical audience, and to provide a primarily statistical treatment of the lessons that have been learned from this remarkable set of data.

description: Quasars with a high redshift (z) are important to understand the evolution processes of galaxies in the early universe. However only a few of these distant objects are known to this date. The costs of building and operating a 10-metre class telescope limit the number of facilities and, thus, the available observation time. Therefore an efficient selection of candidates is mandatory. This paper presents a new approach to select quasar candidates with high redshift (z>4.8) based on photometric catalogues. We have chosen to use the z>4.8 limit for our approach because the dominant Lyman alpha emission line of a quasar can only be found in the Sloan i and z-band filters. As part of the candidate selection approach, a photometric redshift estimator is presented, too. Three of the 120,000 generated candidates have been spectroscopically analysed in follow-up observations and a new z=5.0 quasar was found. This result is consistent with the estimated detection ratio of about 50 per cent and we expect 60,000 high-redshift quasars to be part of our candidate sample. The created candidates are available for download at MNRAS or at http://www.astro.rub.de/polsterer/quasar-candidates.csv.

The Hanle effect is not observed in measurements taken by sweeping a magnetic field at different angles from the plane of the device. As possible explanations we discuss the tilting out of plane of the magnetization of the electrodes, exceptionally high mobility or hot spots. Our results call for a greater understanding of spin injection and transport in such devices.
Cellular structure of $q$-Brauer algebras

description: In this paper we consider the $q$-Brauer algebra over $R$ a commutative noetherian domain. We first construct a new basis for $q$-Brauer algebras, and we then prove that it is a cell basis, and thus these algebras are cellular in the sense of Graham and Lehrer. In particular, they are shown to be an iterated inflation of Hecke algebras of type $A_{n-1}.$ Moreover, when $R$ is a field of arbitrary characteristic, we determine for which parameters the $q$-Brauer algebras are quasi-heredity. So the general theory of cellular algebras and quasi-hereditary algebras applies to $q$-Brauer algebras. As a consequence, we can determine all irreducible representations of $q$-Brauer algebras by linear algebra methods.

description: We present a new energy-dependent partial-wave analysis of all antiproton-proton elastic and charge-exchange scattering data below 925 MeV/c antiproton laboratory momentum. The long-range parts of the chiral one- and two-pion exchange interactions are included exactly. The short-range interactions, including the coupling to the mesonic annihilation channels, are parametrized by a complex boundary condition at a radius of r=1.2 fm. The updated database, which includes significantly more high-quality charge-exchange data, contains 3749 scattering data. The fit results in chi^2_min/N_df=1.048, where N_df=3578 is the number of degrees of freedom. We discuss the description of the experimental data and we present the antiproton-proton phase-shift parameters.

description: We study topological excitations in spin-1 Bose-Einstein condensates trapped in an elongated double-well optical potential. This system hosts a new topological defect, the spin Josephson vortex (SJV), which forms due to the competition between the inter-well atomic tunneling and short-range ferromagnetic two-body interaction. We identify the spin structure and formation dynamics of the SJV and determine the phase diagram of the system. By exploiting the intrinsic stability of the SJV, we propose a dynamical method to create SJVs under realistic experimental conditions.

Media, Milieu, and Community
Creators: name: Huber, Fabian
Publisher: name: Online - Heidelberg Journal of Religions on the Internet
Year: 2019

description: This article examines the role of media in the process of religious communalization (Vergemeinschaftung), drawing on the example of the Evangelical Association of Vineyard Churches. It argues that a direct connection between media production, media use, and integration in the community is too shortsighted. Instead, the empirical study will demonstrate how different media – including those produced by various Vineyard churches – circulate in a specific milieu. It is within this milieu, with its constellation of local celebrations, Bible studies and regional events, that the members of Vineyard churches (re)construct their religious belonging in a complex interplay of face-to-face and media-based communication. In the end, the analysis highlights the multilayered role of media within and beyond the Association of Vineyard Churches and provides a contribution to the conceptual clarification of ‘community’.

description: We consider the specification of prior distributions for Bayesian model comparison, focusing on regression-type models. We propose a particular joint specification of the prior distribution across models so that sensitivity of posterior model probabilities to the dispersion of prior distributions for the parameters of individual models (Lindley's paradox) is diminished. We illustrate the behavior of inferential and predictive posterior quantities in linear and log-linear regressions under our proposed prior densities with a series of simulated and real data examples.

title: Anforderungsspezifische Einstellung des Eigenspannungszustands in der Kaltmassivumformung
Creators: name: Franceschi, Alessandro
Publisher: name: UNSPECIFIED
Year: 2023

description: In der metallverarbeitenden Industrie werden Eigenspannungen bislang aufgrund ihrer negativen und insbesondere schwerwiegenden Einflüsse auf Bauteileigenschaften als Störgröße betrachtet. Daher ist es gängige Praxis, Gegenmaßnahmen zur Eigenspannungsbegrenzung zu ergreifen. Überwiegend wird eine Nachbearbeitung durch eine Wärmebehandlung oder eine mechanische Oberflächenbearbeitung abzielen. In der vorliegenden Arbeit wird ein drastischer Paradigmenwechsel bei der Herstellung von achsensymmetrischen kaltfließgepressten Bauteilen angestrebt. Ziel der vorliegenden Arbeit ist es, die Leistungsfähigkeit dieser Komponente durch eine bewusste, anforderungsspezifische und systematische Optimierung ihres Spannungszustandes zu verbessern. Dieser Prozess wird als „Maßgeschneidertes Eigenspannungsdesign“ (engl. Tailored Residual Stress Design) bezeichnet. Achsensymmetrische Kaltumformprozesse bieten aufgrund ihrer Beschaffenheit besondere Möglichkeiten zur Eigenspannungsanpassung und zur analytischen Beschreibung der zugrundeliegenden Phänomene. Für zwei Mechanismen der Spannungsüberlagerung erfolgt eine Definition sowie eine neuartige analytische Modellierung. Diese sind die Teil- und Vollumformung. Diese neuen Erkenntnisse werden auf das Voll-Vorwärts Fließpressen angewandt. Zwei Systeme zur selektiven Steuerung des Spannungszustands während des Umformprozesses werden für das Voll-Vorwärts Fließpressen entwickelt. Die Eigenspannungen können durch den Einsatz eines Gegenstempels während der Hauptumformung oder durch die Steuerung der Matrizenvorspannung während der Ausstoßphase kontrolliert werden. Beide Strategien werden durch FE-Simulationen untersucht und experimentell durch Röntgenbeugung und qualitative zerstörende Messmethoden validiert. Experimentell lässt sich zeigen, dass die hergestellten Teile deutlich bessere Eigenschaften hinsichtlich ihrer Dauerfestigkeit sowie ihrer Korrosionsbeständigkeit aufweisen. Zusätzlich wird auch eine Vermeidung von Verzug festgestellt Schließlich wird die Kombination der beiden Strategien numerisch untersucht. Es zeigt sich, dass das Spektrum des erreichbaren Eigenspannungsprofils durch eine gezielte Steuerung der Teil- und Vollumformung erweitert werden kann. Auf der Grundlage der Simulationen wird ein analytisches Tool für die direkte Korrelation von steuerbaren Eingangsparametern und Endspannungszuständen erstellt. Dies bietet die Grundlage für die Realisierung einer systematischen anforderungsspezifischen Anpassung des Eigenspannungszustands während der Produktion.

description: The Conference Proceedings are an impressive display of the current scope of Ecological Informatics. Whilst Data Management, Analysis, Synthesis and Forecasting have been lasting popular themes over the past nine biannual ICEI conferences, ICEI 2018 addresses distinctively novel developments in Data Acquisition enabled by cutting edge in situ and remote sensing technology. The here presented ICEI 2018 abstracts captures well current trends and challenges of Ecological Informatics towards: • regional, continental and global sharing of ecological data, • thorough integration of complementing monitoring technologies including DNA-barcoding, • sophisticated pattern recognition by deep learning, • advanced exploration of valuable information in ‘big data’ by means of machine learning and process modelling, • decision-informing solutions for biodiversity conservation and sustainable ecosystem management in light of global changes.

description: In multi-band systems, electrons from different orbitals coexist at the Fermi surface. An attractive interaction among these quasi-particles gives rise to inter-band or hybrid pairs which eventually condense in a superconducting state. These quasi-particles have a natural mismatch of their Fermi wave-vectors, $δk_F$, which depends on the strength of the hybridization between their orbitals. The existence of this natural scale suggests the possibility of inhomogeneous superconducting ground states in these systems, even in the absence of an applied magnetic field. Furthermore, since hybridization $V$ depends on pressure, this provides an external parameter to control the wave-vectors mismatch at the Fermi surface. In this work, we study the phase diagram of a two-dimensional, two-band metal with inter-band pairing. We show that as the mismatch between the Fermi wave-vectors of the two hybrid bands is reduced, the system presents a normal-to-inhomogeneous superconductor quantum phase transition at a critical value of the hybridization $V_c=Δ_0$. The superconducting ground state for $V

description: Here we describe a compact and efficient strontium oven well suited for laser-cooling experiments. Novel design solutions allowed us to produce a collimated strontium atomic beam with a flux of 1.0\times10^13 s^-1 cm^-2 at the oven temperature of 450 °C, reached with an electrical power consumption of 36 W. The oven is based on a stainless-steel reservoir, filled with 6 g of metallic strontium, electrically heated in a vacuum environment by a tantalum wire threaded through an alumina multi-bore tube. The oven can be hosted in a standard DN40CF cube and has an estimated continuous operation lifetime of 10 years. This oven can be used for other alkali and alkaline earth metals with essentially no modifications.
