description: Axions with mass greater than 0.7 eV are excluded by cosmological precision data because they provide too much hot dark matter. While for masses above 20 eV the axion lifetime drops below the age of the universe, we show that the cosmological exclusion range can be extended from 0.7 eV till 300 keV, primarily by the cosmic deuterium abundance: axion decays would strongly modify the baryon-to-photon ratio at BBN relative to the one at CMB decoupling. Additional arguments include neutrino dilution relative to photons by axion decays and spectral CMB distortions. Our new cosmological constraints complement stellar-evolution limits and laboratory bounds.

description: Objects of research: ear canal and tympanic membrane. The purpose of the work is determination of the temperature field in the ear canal and on the tympanic membrane and assessment of the temperature changes in the ear canal in the direction from the tympanic membrane to the auricle. In the process of work the following steps were taken for the set of models, where the geometric features were gradually refined: 1. Preparing the CAD-model of the ear canal, tympanic membrane and surrounding organs and tissues. 2. Preparing a finite element model based on the CAD-model. 3. Carrying out simulation of the problem. 4. Analysis of the results. As a result, the temperature field of the ear canal and an estimate of its changes are obtained.

Experimental study of the pre-gelation behaviour of composite prepreg
Creators: name: Duffner, Caitlin
Publisher: name: University of British Columbia
Year: 2019

description: As the composite industry grows, the science base that supports the industry must also grow. In the past, most of the work done on thermoset composite prepreg systems have studied the post –gelation response, leaving the initial condition of the material relatively unexplored. The initial, or pre-gelation, state of the material is becoming increasingly relevant as the industry transitions to new manufacturing processes, mainly automatic fibre placement (AFP) and forming, that handles and manipulates the raw prepreg. Recent works investigating manufacturing defects in composite parts have shown a strong connection between the initial condition of the material and the final part quality. As research and industry shift to working with raw prepreg, it is time to re-examine the pre-gelation behaviour in order to improve processes in the future. This work studies the pre-gelation behaviour of unidirectional Hexcel AS4/8552 prepreg through several novel test methods. The methods presented offer a different perspective into the behaviour of the material. Initially a microscopic perspective was taken, and SEM microscopy was used to characterize the initial morphology of a ply of prepreg. This study presents the significance of variations in morphology and the impact of capillary flow driven ply consolidation. Next, to evaluate the macroscopic behaviour of prepreg, a non-contact approach using Digital Image Correlation (DIC) was developed. This method was able to capture global and local strain responses in the prepreg throughout processing. Findings show that the pre-gelation response is not as simple as previously thought. The material experiences a strong consolidating force when heated due to the effects of surface tension. Further tests performed in this study attempt to make connections between local morphology, resin variations and local variations in strain. These tests used DIC, IR thermography, optical microscopy, and SEM. New insights into prepreg conditions are gained by evaluating the common trends seen with this suite of testing. This work concludes that pre-gelation behaviour in prepreg is a highly complex state dependent on the variability of the material and the liquid-solid interfaces in the ply, as opposed to the traditional approach which considers the material response through a solid mechanics lens.

An actively accreting massive black hole in the dwarf starburst galaxy Henize 2-10

description: Supermassive black holes are now thought to lie at the heart of every giant galaxy with a spheroidal component, including our own Milky Way. The birth and growth of the first 'seed' black holes in the earlier Universe, however, is observationally unconstrained and we are only beginning to piece together a scenario for their subsequent evolution. Here we report that the nearby dwarf starburst galaxy Henize 2-10 contains a compact radio source at the dynamical centre of the galaxy that is spatially coincident with a hard X-ray source. From these observations, we conclude that Henize 2-10 harbours an actively accreting central black hole with a mass of approximately one million solar masses. This nearby dwarf galaxy, simultaneoulsy hosting a massive black hole and an extreme burst of star formation, is analogous in many ways to galaxies in the infant Universe during the early stages of black-hole growth and galaxy mass assembly. Our results confirm that nearby star-forming dwarf galaxies can indeed form massive black holes, and that by implication so can their primordial counterparts. Moreover, the lack of a substantial spheroidal component in Henize 2-10 indicates that supermassive black-hole growth may precede the build-up of galaxy spheroids.

description: Posterbeitrag zum hochschulsensiblen Verständnis der digiatlen Transformation auf der Fachtagung "Vernetzte Hochschule – Netzwerke für die Lehre" an der TU Darmstadt am 13.11.2018. Das vom BMBF geförderte Projekt Qualitätssicherung in der Digitalisierungsstrategie (QuaSiD) untersucht Erfolgsfaktoren und Akteurskonstellationen bei der Verbreitung und Verankerung von Digitalisierungsprojekten innerhalb von Digitalisierungsstrategien an Hochschulen. Dabei wird insbesondere das Feld der digital unterstützten Lehre in den Fokus genommen. Im Rahmen des Projekts wurden ein Verständnis des Strategie- sowie des Digitalisierungsbegriffs unter den besonderen organisationalen Voraussetzungen von Hochschulen entwickelt, die werden hier in Form eines Posterbeitrags präsentiert.
 Die Digitalisierung der Lehre wird als ein Veränderungsprozess im Sinne einer Erweiterung der Hochschullehre durch Digitalisierung verstanden. Dieser strategische Prozess erfolgt nicht geradlinig, bspw. top-down, sondern als ein aktiver und reaktiver Prozess, bestehend aus mehreren Subprozessen mit jeweils eigenen Zielen. Folglich bestehen Digitalisierungsstrategien im Verständnis von QuaSiD aus einer Vielzahl kleinteiliger strategischer Prozesse. Innerhalb dieser Veränderungsprozesse lassen sich heterogene Konstellationen von sozialen Akteuren, sachlichen Elementen (wie etwa Technologien oder rechtliche Rahmenbedingungen) und zeitlich‐räumlichen Strukturen erkennen, dessen Zusammenspiel im Sinne einer Vernetzung und Kooperation entscheidend für den Erfolg des Veränderungsprozesses sind. Denn erst in der weiteren Entwicklung und durch. Vernetzung und Kooperation der sozialen Akteure fügen sich diese Subprozesse zu einer größeren – hochschulweiten – Digitalisierungsstrategie zusammen.
Size Effects on Transport Properties in Topological Anderson Insulators

description: We study the size effects on the transport properties in topological Anderson insulators by means of the Landauer-Büttiker formalism combined with the nonequilibrium Green function method. Conductances calculated for serval different widths of the nanoribbons reveal that there is no longer quantized plateaus for narrow nanoribbons. The local spin-resolved current distribution demonstrates that the edge states on the two sides can be coupled, leading to enhancement of backscattering as the width of the nanoribbon decreases, thus destroying the perfect quantization phenomena in the topological Anderson insulator. We also show that the main contribution to the nonquantized conductance also comes from edge states. Experiment proposals on topological Anderson insulator are discussed finally.

description: Real and virtual corrections in NNLO QCD require multi-dimensional integrals with overlapping singularities. We first review ideas and methods which have been proposed for performing such computations. We then present a new method for the factorization of overlapping singularities based on non-linear integral transformations. We apply this method for the evaluation of all integral topologies which appear in double real radiation corrections in cross-section calculations for the production of a heavy system at hadron colliders. Finally, we demonstrate with typical examples that two-loop virtual corrections are amenable to the same method.

description: This volume of essays addresses the representation of the Second World War in museums and memorials in Eastern Europe. It is the product of a research project funded by the Volkswagen Foundation, bringing together fourteen detailed accounts in German and English of the historical development of such institutions in a range of contexts, including Russia, Belarus, Ukraine, Poland and Romania. Apart from one anomalous chapter that details the development of the Dachau concentration camp memorial, the central focus of the volume is on the transition between the antifascist narrative propagated by state socialist regimes in the region to a variety of post-socialist memory cultures. These memory cultures have been determined in each case both by domestic politics in the individual countries and their respective geopolitical circumstances.

description: One of the greatest problems of standard cosmology is the Big Bang singularity. Previously it has been shown that non-local ghostfree higher-derivative modifications of Einstein gravity in the ultra-violet regime can admit non-singular bouncing solutions. In this paper we study in more details the dynamical properties of the equations of motion for these theories of gravity in presence of positive and negative cosmological constants and radiation. We find stable inflationary attractor solutions in the presence of a positive cosmological constant which renders inflation {\it geodesically complete}, while in the presence of a negative cosmological constant a cyclic universe emerges. We also provide an algorithm for tracking the super-Hubble perturbations during the bounce and show that the bouncing solutions are free from any perturbative instability.

description: We relate the observable number of sources per solid angle and redshift to the underlying proper source density and velocity, background evolution and line-of-sight potentials. We give an exact result in the case of linearized perturbations assuming general relativity. This consistently includes contributions of the source density perturbations and redshift distortions, magnification, radial displacement, and various additional linear terms that are small on sub-horizon scales. In addition we calculate the effect on observed luminosities, and hence the result for sources observed as a function of flux, including magnification bias and radial-displacement effects. We give the corresponding linear result for a magnitude-limited survey at low redshift, and discuss the angular power spectrum of the total count distribution. We also calculate the cross-correlation with the CMB polarization and temperature including Doppler source terms, magnification, redshift distortions and other velocity effects for the sources, and discuss why the contribution of redshift distortions is generally small. Finally we relate the result for source number counts to that for the brightness of line radiation, for example 21-cm radiation, from the sources.

description: The increasing amount and diversity of data in life sciences is revolutionising the field. Proportionally, a diversity of computational expertise is needed in order to manage, process, analyse and synthesise such data. The Bio-IT project was established to foster the development of computational and data science skills and promote the sharing of knowledge and adoption of best practices at EMBL. To achieve this aim, it relies on voluntary contributions, good communication and a welcoming cooperation environment. The project supports and coordinates the efforts of EMBL’s community of practice by nurturing this environment and the human capital behind it. The Bio-IT programme is built on four pillars: I) training and consulting, II) community building and networking, III) infrastructure and resources, and IV) knowledge aggregation and dissemination. Here, we provide an overview of Bio-IT activities focusing on how and why become a member of the community, specifically: the benefits of involvement as a volunteer, the different ways to support the project, the impact the project is having, the motivations behind a diverse and global participation, hence the importance of demographic representation. We will also present specific sustainability challenges faced by the EMBL community, such as its organisational size, distribution of disciplines and needs across sites and quick turnover of personnel and knowledge. While providing support and guidance to active community members, we will reflect on how to lower barriers for new contributors to ensure successful engagement and leading of activities and teaching, including workshops. Defining personas that capture and represent the diversity of the community, we here also highlight an essential aspect in our plan to strengthen peer-consulting and internal communication and collaboration. Finally, we look ahead to upcoming events and activities, encouraging everyone at EMBL to access our services and contribute to their improvement.

description: Es wäre keine Überraschung gewesen, wenn die polnischen Oppositionsbewegungen der 1970er und 1980er Jahre vierzig Jahre nach ihrer Entstehung heute ausschließlich von der Historikerzunft beforscht würden. Glücklicherweise gibt es aber immer noch SozialwissenschaftlerInnen, die bereit sind, das Jahr 1989 als Zäsur zu hinterfragen und sich mit den vorangegangenen Jahrzehnten zu beschäftigen. Mit Polnischer Protest: Zur pragmatischen Fundierung von Theorien sozialen Wandels hat die Soziologin Hella Dietz eine Studie vorgelegt, die sowohl soziologisch argumentiert als auch tief in die Ereignisse und das Denken dieser lang vergangenen Tage eintaucht. Dietz zufolge verdecken Narrative, die das Jahr 1989 als fundamentalen Bruch verstehen, die vielen Gemeinsamkeiten der vorangegangenen und nachfolgenden Jahre. Aufgrund dieser Gemeinsamkeiten sei eine Analyse der Entstehungsgeschichte polnischer Protestbewegungen der 1970er und 1980er Jahre immer noch interessant und relevant für die Sozialwissenschaften (S. 297).

description: Der Sammelband thematisiert aktuelle Beobachtungen zum Stellenwert feministischen Denkens in der polnischen Gesellschaft. Die Beiträge sind in drei thematische Abschnitte gegliedert: Der erste Teil widmet sich neben einer historischen Beschreibung der Kämpfe um Gleichberechtigung (Urszula Chowaniec, S. 26-46) und der Verortung des polnischen Feminismus im spezifischen Ost-West-Kontext (Rosalind Marsh, S. 47-66) auch der Frage nach dessen Herkunft (Ewa Kraskowska, S. 67-77). Der zweite Teil enthält literaturwissenschaftliche Untersuchungen (Ursula Philips, Grażyna Borkowska, Agnieszka Mrozik, Asia Zgadzaj, Elżbieta Wącik). In einem dritten Schritt werden aktuelle Trends in Film (Ewa Mazierska), Drama (Elwira M. Grossman) und Sprachentwicklung (Dorota Hołowiak) sichtbar gemacht. Ziel ist nicht eine erschöpfende Analyse der „women studies" in Polen, sondern die Darstellung von „women's activities" seit dem 19. Jahrhundert sowie nach 1989.

description: The effective quantum pseudospin-1/2 model for interacting rare-earth magnetic moments, which are locally described with atomic doublets, is studied theoretically for magnetic pyrochlore oxides. It is derived microscopically for localized Pr^{3+} 4f moments in Pr_2TM_2O_7 (TM = Zr, Sn, Hf, and Ir) by starting from the atomic non-Kramers magnetic doublets and performing the strong-coupling perturbation expansion of the virtual electron transfer between the Pr 4f and O 2p electrons. The most generic form of the nearest-neighbor anisotropic superexchange pseudospin-1/2 Hamiltonian is also constructed from the symmetry properties, which is applicable to Kramers ions Nd^{3+}, Sm^{3+}, and Yb^{3+} potentially showing large quantum effects. The effective model is then studied by means of a classical mean-field theory and the exact diagonalization on a single tetrahedron and on a 16-site cluster. These calculations reveal appreciable quantum fluctuations leading to quantum phase transitions to a quadrupolar state as a melting of spin ice for the Pr^{3+} case. The model also shows a formation of cooperative quadrupole moment and pseudospin chirality on tetrahedrons. A sign of a singlet quantum spin ice is also found in a finite region in the space of coupling constants. The relevance to the experiments is discussed.

description: Mit seiner überarbeiteten Habilitationsschrift legt Tobias Weger ein 800 Seiten umfassendes monumentales Werk vor, das den Leser schon auf den ersten Blick stutzig macht. Denn mit Schlesien und Friesland untersucht der Autor zwei in der Zwischenkriegszeit am Rande des Deutschen Reiches befindliche unterschiedliche Räume, die keinerlei historische oder kulturelle Bezüge zueinander aufweisen. Es ist jedoch nicht die Absicht des Verfassers, einen historischen Vergleich zwischen den beiden untersuchten Regionen zu ziehen, es handelt sich vielmehr um eine parallele Narration. Daher ist nur die angewandte Untersuchungsmethodologie vergleichend, die geografischen Räume in ihrer (kultur-) historischen Dimension sind es nicht. Weger verfolgt auch nicht das Ziel, eine generalisierende Theoriebildung im Hinblick auf ethnoregionale Bewegungen zu betreiben, sondern er will dem Leser durch eine systematische Analyse zwei parallele grenzüberschreitende Fallbeispiele der deutsch-slawischen bzw. deutsch-niederländischen Beziehungen in deren ganzer Komplexität näherbringen.

QCDNUM: Fast QCD Evolution and Convolution

Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: The QCDNUM program numerically solves the evolution equations for parton densities and fragmentation functions in perturbative QCD. Un-polarised parton densities can be evolved up to next-to-next-to-leading order in powers of the strong coupling constant, while polarised densities or fragmentation functions can be evolved up to next-to-leading order. Other types of evolution can be accessed by feeding alternative sets of evolution kernels into the program. A versatile convolution engine provides tools to compute parton luminosities, cross-sections in hadron-hadron scattering, and deep inelastic structure functions in the zero-mass scheme or in generalised mass schemes. Input to these calculations are either the QCDNUM evolved densities, or those read in from an external parton density repository. Included in the software distribution are packages to calculate zero-mass structure functions in un-polarised deep inelastic scattering, and heavy flavour contributions to these structure functions in the fixed flavour number scheme.

description: Posterbeitrag zur Vorstellung der Kollektiven Veränderungsbereitschaft als ein bedeutender Erfolgsfaktor bei der digitalen Transformation der Hochschullehre auf der Fachtagung: "20. DINI-Jahrestagung 1999-2019-2039: Innovative Projekte in Forschung, Lehre und Infrastruktur" in Osnabrück am 08. und 09.10.2019. Die Digitalisierung in der Hochschullehre stellt einen Veränderungsprozess dar, der als solcher geleitet werden muss. Das BMBF-geförderte Projekt Qualitätssicherung in der Digitalisierungsstrategie (QuaSiD) untersucht empirisch Erfolgsfaktoren und Akteurskonstellationen bei der nachhaltigen Verbreitung und Verankerung der Digitalisierung der Hochschullehre und möchte ein Teilergebnis in Form eines Posterbeitrags präsentieren. Aufgrund der Organisationsstrukturen im deutschen Hochschulwesen, schlagen wir vor, das Konzept der Veränderungsbereitschaft aus dem Change-Management zu erweitern und konkret von kollektiver Veränderungsbereitschaft als Erfolgsfaktor zu sprechen. Sie entsteht aus dem Zusammenspiel von sechs sich gegenseitig bedingenden Strategien. Im Zentrum steht die soziale Akzeptanz und Legitimität der Veränderung, wonach akzeptiert wird, dass die Digitalisierung notwendig ist und einen Mehrwert hat. Auf struktureller Ebene braucht es dafür eine Ermöglichungskultur sowie Freiräume und die Möglichkeit situationsadäquaten, dynamischen Handelns. Des Weiteren braucht es ebenso eine Transparenz und Sichtbarkeit der Prozesse und Akteure sowie Austausch- und Abstimmungsgelegenheiten um die dynamischen Prozesse in Richtung einer gemeinsamen Entwicklung zu führen. Auf individueller Ebene muss des Weiteren der Nutzen sichtbar und akzeptiert werden sowie die Veränderungsmöglichkeit der Akteure gefördert werden. Jede der sechs Strategien hat einen jeweils eigenen Effekt auf die kollektive Veränderungsbereitschaft sowie auf die anderen Strategien. Sie müssen daher für einen erfolgsversprechenden Prozess in ein situationsadäquates Gleichgewicht gebracht werden.

description: Recently, quantum dimer models, in which the system can tunnel between different classical dimer configurations, have attracted a great deal of interest as a paradigm for the study of exotic quantum phases. Much of this excitement has centred on the claim that a certain class of quantum dimer model, defined on a bipartite lattice, can support a quantum U(1)-liquid phase with deconfined fractional excitations in three dimensions. These fractional monomer excitations are quantum analogues of the magnetic monopoles found in spin ice. In this article we use extensive quantum Monte Carlo simulations to establish the ground-state phase diagram of the quantum dimer model on the three-dimensional, bipartite, diamond lattice as a function of the ratio μ of the potential to kinetic energy terms in the Hamiltonian. We find that, for μ_c = 0.75 +/- 0.04, the model undergoes a first-order quantum phase transition from an ordered "R-state" into an extended quantum U(1)-liquid phase, which terminates in a quantum critical "RK point" for μ=1. This confirms the published field-theoretical scenario. We present detailed evidence for the existence of the U(1)-liquid phase, and indirect evidence for the existence of its photon and monopole excitations. We also explore some of the technical ramifications of this analysis, benchmarking quantum Monte Carlo against a variety of exact and perturbative results, comparing different variational wave functions. The ergodicity of the quantum dimer model on a diamond lattice is discussed in detail. These results complete and extend the analysis previously published in [O. Sikora et al., Phys. Rev. Lett. 103, 247001 (2009)].

description: This collection of over fifty essays is devoted, as the title suggests, to a number of lesser known authors of Polish literature of the late nineteenth and early twentieth century. Instead of limiting the subject of the volume to well-known themes of late romanticism, positivism and Young Poland (as Polish modernism was widely known), one of the main aims of the book is to present authors and works that did not fit into these pre-defined terms. The writers presented in Literatura niewyczerpana are people who created outside the mainstream, or who crossed the boundaries of literary epochs. Significantly, the collection is not only about those who were forgotten and lesser known literary figures, but also about recognised authors and their less popular writings. By avoiding any clear-cut categories when it comes to the periodization of the history of Polish literature, the book brings together essays which could be interesting for readers from beyond the discipline of literary studies.

description: Fermilab operates the world's most intense antiproton source. Newly proposed experiments can use those antiprotons either parasitically during Tevatron Collider running or after the Tevatron Collider finishes. For example, the annihilation of 8 GeV antiprotons is expected to yield world-leading sensitivities to hyperon rare decays and CP violation. It could also provide the world's most intense source of tagged D^0 mesons, and thus the best near-term opportunity to study charm mixing and, via CP violation, to search for new physics. Other precision measurements that could be made include properties of the X(3872) and the charmonium system. An experiment using a Penning trap and an atom interferometer could make the world's first measurement of the gravitational force on antimatter. These and other potential measurements using antiprotons could lead to a broad physics program at Fermilab in the post-Tevatron era.
