description: We present the experimental test of a method for controlling the absolute length of the diagonals of square ring laser gyroscopes. The purpose is to actively stabilize the ring cavity geometry and to enhance the rotation sensor stability in order to reach the requirements for the detection of the relativistic Lense-Thirring effect with a ground-based array of optical gyroscopes. The test apparatus consists of two optical cavities 1.32 m in length, reproducing the features of the ring cavity diagonal resonators of large frame He-Ne ring laser gyroscopes. The proposed measurement technique is based on the use of a single diode laser, injection locked to a frequency stabilized He-Ne/Iodine frequency standard, and a single electro-optic modulator. The laser is modulated with a combination of three frequencies allowing to lock the two cavities to the same resonance frequency and, at the same time, to determine the cavity Free Spectral Range (FSR). We obtain a stable lock of the two cavities to the same optical frequency reference, providing a length stabilization at the level of 1 part in $10^{11}$, and the determination of the two FSRs with a relative precision of 0.2 ppm. This is equivalent to an error of 500 nm on the absolute length difference between the two cavities.

description: Insects use their mandibles for a variety of tasks, including cutting and material transport, defence, building nests, caring for brood and competing for mates. Despite this functional diversity, mandible motion is thought to be constrained to rotation about a single fixed axis in the majority of extant species. Here, we conduct a direct quantitative test of this ‘hinge joint hypothesis’ in a species that uses its mandibles for a wide range of tasks: Atta vollenweideri leaf-cutter ants. Mandible movements from live restrained ants were reconstructed in three-dimensional using a multi-camera rig. Rigid body kinematic analyses revealed strong evidence that mandible movement occupies a kinematic space which requires more than one rotational degree of freedom: at large opening angles, mandible motion is dominated by yaw. But at small opening angles, mandibles yaw and pitch. The combination of yaw and pitch allows mandibles to ‘criss-cross’: either mandible can be on top when mandibles are closed. We observed criss-crossing in freely cutting ants, suggesting that it is functionally important. Combined with recent reports on diversity of joint articulations in other insects, our results show that insect mandible kinematics are more diverse than traditionally assumed, and thus worthy of further detailed investigation.This article is part of the theme issue ‘Food processing and nutrition assimilation in animals’.

description: Zentrales Anliegen der Lehrer*innenbildung ist es, Schnittstellen zwischen Theorie und Praxis zu gestalten und bei den Studierenden nach dem Leitbild des „reflective practitioner“ eine wissenschaftlich-reflexive Haltung anzubahnen. Dieser Beitrag skizziert eine Seminareinheit, in der im Vorbereitungsseminar für ein Schulpraktikum im Fach Biologie durch einen aufgabenbasierten Ansatz Theorie-Praxis-Bezüge hergestellt werden. Dazu wird exemplarisch zum Thema „Umgang mit Schüler*innenvorstellungen zur Immunbiologie“ ein Aufgabensetting vorgestellt, das die Studierenden innerhalb des Seminars bearbeiten. Darüber hinaus erhalten die Studierenden für das Schulpraktikum Aufgaben und Unterstützungstools (Prompts) zum Reflektieren über Biologieunterricht. Intention der Seminaraufgaben und Prompts für das Schulpraktikum ist, dass die Studierenden grundlegendes biologiedidaktisches Theoriewissen erwerben und darüber hinaus fachspezifisches Reflektieren angeregt wird. Die Förderung dieser professionalisierungsrelevanten Kompetenzen wird gezielt mit der e-Portfolio-Methode (Open Source Software Mahara) verknüpft.

description: A low loss (LL) type 500 MHz 5-cell superconducting niobium prototype cavity with large beam aperture has been developed successfully including the optimization, the deep drawing and electron beam welding, the surface treatment and the vertical testing. The performance of the fundamental mode was optimized and the higher order modes were damped by adopting an enlarged beam pipe for propagation. Surface preparation or treatment including mechanical polishing, buffered chemical polishing and high pressure rinsing with ultra-pure water and so on was carried out carefully to promise a perfect inner surface condition. The vertical testing results show that the accelerating voltage higher than 7.5 MV was obtained while the quality factor was better than 1E9 at 4.2 K. No obvious multipacting or field emission was found during the test. However, a quench happened while increasing the field a little higher than 7.5 MV that at present limited the cavity performance.

description: Das Schulfach Sport nimmt eine Sonderstellung ein, die auch in die universitäre Sportlehramtsausbildung hineinwirkt und eine bedachte wie konstruktive Begleitung von Sportlehramtspraktikant*innen erfordert. Berücksichtigt man die eigene Sportsozialisation vieler Sportstudierender und die Vielzahl kontraindizierter Fachzuschreibungen, ist eine wissenschaftliche Begleitung von Praktikumsphasen in der Professionalisierung zur Sportlehrkraft essenziell. Die Anfertigung eines praxisbegleitenden Portfolios kann in diesem Kontext vielseitige Entwicklungsfortschritte festhalten und sichtbar machen. Der vorliegende Beitrag stellt die Evaluation eines praktikumsbegleitenden Portfolios mit den Bestandteilen ausführlicher Unterrichtsentwurf, Reflexion der eigenen Entwicklung sowie literaturbasierte Auseinandersetzung aus Studierendenperspektive und nach Abschluss des Praktikums dar. Der ausführliche Unterrichtsentwurf und somit die Aufgabenstellungen mit dem deutlichsten Bezug zum Sportunterricht und zum Referendariat werden von den Studierenden vergleichsweise am sinn- und wertvollsten für ihre Weiterentwicklung angesehen. Die beiden anderen Aufgabenstellungen werden vergleichsweise schwächer bewertet und teilen das Charakteristikum einer zugrundeliegenden, fundierten Einarbeitung in theoretische bzw. empirische Hintergründe, inklusive eines Abgleichs praktischer Erfahrungen. Gefragt nach eigenen Ideen für eine Formulierung von Portfolioaufgaben wird deutlich, dass ein Wunsch nach mehr Raum für die Darstellung praktischer Erfahrungen und weniger Literaturarbeit besteht. Die Ergebnisse liefern Anhaltspunkte für die Weiterentwicklung des Gesamtkonzepts, um die Studierenden besser und nachvollziehbarer in ihrer Professionalisierung zu unterstützen.

A Bayesian Approach for Noisy Matrix Completion: Optimal Rate under General Sampling Distribution

description: Bayesian methods for low-rank matrix completion with noise have been shown to be very efficient computationally. While the behaviour of penalized minimization methods is well understood both from the theoretical and computational points of view in this problem, the theoretical optimality of Bayesian estimators have not been explored yet. In this paper, we propose a Bayesian estimator for matrix completion under general sampling distribution. We also provide an oracle inequality for this estimator. This inequality proves that, whatever the rank of the matrix to be estimated, our estimator reaches the minimax-optimal rate of convergence (up to a logarithmic factor). We end the paper with a short simulation study.
Qualitätsentwicklung von und durch Portfolioarbeit

description: Portfolio und Portfolioarbeit sind seit der Jahrtausendwende viel gebrauchte Schlagworte im Bildungssektor. Sie gelten auch in der Lehrer*innenbildung national und international als Innovation. Aktuell werden Portfoliokonzepte auch vor dem Hintergrund ministerialer Vorgaben in die Lehrer*innenbildung implementiert – dies, obwohl die Forschungslage zur Arbeit mit Portfolios nach wie vor wenig belastbar ist. Wer sich aktuell oder künftig professionell mit Portfolios in der Lehrer*innenbildung befasst, muss sich früher oder später mit Fragen der Qualitätssicherung bzw. -entwicklung beschäftigen. Da sich die Portfolioarbeit selbst als Ansatzpunkt der Qualitätsentwicklung von Lehr-Lern-Settings versteht, ist zu unterscheiden zwischen Qualitäten von Portfolioarbeit und Qualitäten durch Portfolioarbeit. Während mit Qualität von Portfolioarbeit die Frage der konzeptadäquaten Umsetzung adressiert wird, geht es bei der Frage nach der Qualität durch Portfolioarbeit um Erforschung ihrer Potenziale. Beide Zugänge haben ein gemeinsames Grundproblem: die Frage, was denn eigentlich mit den Begriffen Portfolio und Portfolioarbeit gemeint ist. Hinter dem Portfolioansatz verbirgt sich ein besonderer Lern-, Denk- und Arbeitsstil. Je nachdem, welche Lesart des Grundkonzepts gewählt wird, wirkt sich das auf Fragen der Qualität von und durch Portfolioarbeit aus, d.h. auf Konzeptevaluationen bzw. die Erforschung von Potenzialen. Während Konzeptevaluationen vor der Aufgabe stehen, deduktiv Checklisten mit Orientierungspunkten und Indikatoren zu entwickeln, die versuchen, die gewählte Lesart von Portfolioarbeit so gut wie möglich abzubilden, ist die Wirkungsforschung aus methodischen Gründen auf Vereinheitlichungen angewiesen. Um die zutiefst partizipative Grundidee und die konzeptionell gewünschte Vielfalt des Portfolioansatzes nicht vorschnell einem methodologischen Reduktionismus zu opfern, indem erstens aus forschungsmethodischen Gründen die Standardisierung von Portfoliokonzepten betrieben wird bzw. zweitens die Forschung sich auf die in der programmatischen Literatur unterstellten Potenziale beschränkt, wird angeregt, Forschungsperspektiven zu erweitern. Entsprechend wird zusätzlich eine stärker explorative Erforschung nicht nur der unterstellten Wirkungen, sondern auch der sich zeigenden positiven Nebenwirkungen insbesondere auch mit empirisch-rekonstruktiven Methoden empfohlen. Dies könnte neben noch unerkannten Risiken auch unvermutete Potenziale der Nutzung von Portfolios ans Licht bringen. Darauf will der Beitrag hinweisen.

Pulsations of red supergiant pair-instability supernova progenitors leading to extreme mass loss

Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Recent stellar evolution models show consistently that very massive metal-free stars evolve into red supergiants shortly before they explode. We argue that the envelopes of these stars, which will form pair-instability supernovae, become pulsationally unstable and that this will lead to extreme mass-loss rates despite the tiny metal content of the envelopes. We investigate the pulsational properties of such models and derive pulsationally induced mass-loss rates, which take the damping effects of the mass loss on the pulsations selfconsistently into account. We find that the pulsations may induce mass-loss rates of ~ 1e-4 - 1e-2 Msun/yr shortly before the explosions, which may create a dense circumstellar medium. Our results show that very massive stars with dense circumstellar media may stem from a wider initial mass range than pulsational-pair instability supernovae. The extreme mass loss will cease when so much of the hydrogen-rich envelope is lost that the star becomes more compact and stops pulsating. The helium core of these stars therefore remains unaffected, and their fate as pair-instability supernovae remains unaltered. The existence of dense circumstellar media around metal-free pair-instability supernovae can make them brighter and bluer, and they may be easier to detect at high redshifts than previously expected. We argue that the mass-loss enhancement in pair-instability supernova progenitors can naturally explain some observational properties of superluminous supernovae: the energetic explosions of stars within hydrogen-rich dense circumstellar media with little 56Ni production and the lack of a hydrogen-rich envelope in pair-instability supernova candidates with large 56Ni production.

description: We discuss the large-distance approximation of the monopole-vortex complex soliton in a hierarchically broken gauge system, SU(N+1) - > SU(N) x U(1) - > 1, in a color-flavor locked SU(N) symmetric vacuum. The ('t Hooft-Polyakov) monopole of the higher-mass-scale breaking appears as a point and acts as a source of the thin vortex generated by the lower-energy gauge symmetry breaking. The exact color-flavor diagonal symmetry of the bulk system is broken by each individual soliton, leading to nonAbelian orientational CP^{N-1} zeromodes propagating in the vortex worldsheet, well studied in the literature. But since the vortex ends at the monopoles these fluctuating modes endow the monopoles with a local SU(N) charge. This phenomenon is studied by performing the duality transformation in the presence of the CP^{N-1} moduli space. The effective action is a CP^{N-1} model defined on a finite-width worldstrip.

description: We study attractively interacting fermions on a square lattice with dispersion relations exhibiting strong spin-dependent anisotropy. The resulting Fermi surface mismatch suppresses the s-wave BCS-type instability, clearing the way for unconventional types of order. Unbiased sampling of the Feynman diagrammatic series using Diagrammatic Monte Carlo methods reveals a rich phase diagram in the regime of intermediate coupling strength. Instead of a proposed Cooper-pair Bose metal phase [A. E. Feiguin and M. P. A. Fisher, Phys. Rev. Lett. 103, 025303 (2009)] we find an incommensurate density wave at strong anisotropy and two different p-wave superfluid states with unconventional symmetry at intermediate anisotropy.

description: This poster presents a large-scale air quality collective measurement (xAire), that followed a citizen science methodology. A broad partnership with 1,650 people from communities around 18 primary schools across Barcelona provided the capacity to obtain unprecedented high-resolution NO2 (nitrogen dioxide) levels. The communities first collectively identified the relevant spots to be measured in their neighborhoods. In a well- coordinated effort, they placed at the same time 800 diffusion tubes in the proximity of 18 primary schools. The tubes were collected exactly 4 weeks after.
This way, new and precise information on the air quality in the vicinity of the schools was obtained. These data and their interpretation were presented by the kids to the City Council authorities. The results encourage strengthening collaboration with local communities when exploring environmental health issues.These new data also made possible an updated asthma Health Impact Assessment. It is shown that NO2 levels vary considerably with at some cases very high levels. More than a 1,000 new cases of childhood asthma could be prevented each year by lowering NO2 levels. Also, predictive NO2 models in the city have incorporated this citizen science data as a reliable data source. The data have had the models capacity to improve the spatial high resolution. After the project, families and schools have been able to better assess and to take individual and collective actions to mitigate NO2 conccentration levels around the schools and in each neighborhood. Finally, the results were published in the form of scientific paper, the data were published as Open Data and the protocol reported in a specialized scientific journal (MethodsX), in order to maximize the reproducibility of the study.

description: Upcoming X-ray surveys like eROSITA require precise calibration between X-ray observables and mass down to the low mass regime to set tight constraints on the fundamental cosmological parameters. Since an individual mass measurement is only possible for a relatively small number of objects it is crucial to have robust and well understood scaling relations that relate the total mass to easily observable quantities. The main goal of this work is to constrain the galaxy group scaling relations corrected for selection effects, and to quantify the influence of non-gravitational physics at the low-mass regime. We analyzed XMM-Newton observations for a complete sample of galaxy groups selected from the ROSAT All-Sky Survey and we compared the derived scaling properties with a galaxy cluster sample. To investigate the role played by the different non-gravitational processes we then compared the observational data with the predictions of hydrodynamical simulations. After applying the correction for selection effects (e.g. Malmquist bias) the L-M relation is steeper than the observed one. Its slope is also steeper than the value obtained by using the more massive systems of the HIFLUGCS sample. This behaviour can be explained by a gradual change of the true L-M relation which should be taken into account when converting the observational parameters into masses. The other observed scaling relations (not corrected for selection biases) do not show any break although the comparison with the simulations suggests that feedback processes play an important role in the formation and evolution of galaxy groups. Thanks to our master sample of 82 objects spanning two order of magnitude in mass we tightly constrain the dependence of the gas mass fraction on the total mass, finding almost a factor of two difference between groups and clusters.

description: Metal Scrap is a term that refers to rejected metal, metallic material, and any product
containing metal that may be recycled after consumption or product creation. Metal scraps are
gathered from different places like manufacturing, buildings, farms, hospitals, residences, and
trash. The Indian government permits the metal scrap import, procedure, and validity which
excludes dangerous, poisonous, or radioactive material. Weapons, mines, ammunition, and
live or spent cartridges are prohibited. Materials like metal scraps are recyclable that are
usually left behind after production or use which is sold and recycled to create fresh material.
Aluminium industry is the largest non-ferrous metal industry in the world and ranks second,
next to steel. Generated scrap should be recycled or removed as hazardous waste.

description: We study the shape of the thick disc using photometric data at high and intermediate latitudes from SDSS and 2MASS surveys. We use the population synthesis approach using an ABC-MCMC method to characterize the thick disc shape, scale height, scale length, local density and flare, and we investigate the extend of the thick disc formation period by simulating several formation episodes. We find that the vertical variation in density is not exponential, but much closer to an hyperbolic secant squared. Assuming a single formation epoch, the thick disc is better fitted with a sech2 scale height of 470 pc and a scale length of 2.3 kpc. However if one simulates two successive formation episodes, mimicking an extended formation period, the older episode has a higher scale height and a larger scale length than the younger episode, indicating a contraction during the collapse phase. The scale height decreases from 800 pc to 340 pc, and the scale length from 3.2 kpc to 2 kpc. The star formation increases from the old episode to the young one. During the fitting process, the halo parameters are also determined. The constraint on the halo shows that a transition between a inner and outer halo, if exists, cannot be at a distance of less than about 30 kpc, which is the limit of our investigation using turnoff halo stars. Finally, we show that extrapolating the thick disc towards the bulge region explains well the stellar populations observed there, that there is no longer need to invoke a classical bulge. To explain these results, the most probable scenario for the thick disc is that it formed while the Galaxy was gravitationally collapsing from well mixed gas-rich giant clumps sustained by high turbulence which awhile prevent a thin disc to form, as proposed by Bournaud et al. (2009). This scenario explains the observations in the thick disc region as well as in the bulge region. (abridged)

description: We report on a mean-field study of spontaneous breaking of chiral symmetry for Dirac fermions with contact interactions in the presence of chiral imbalance, which is modelled by nonzero chiral chemical potential. We point out that chiral imbalance lowers the vacuum energy of Dirac fermions, which leads to the increase of the renormalized chiral chemical potential upon chiral symmetry breaking. The critical coupling strength for the transition to the broken phase is slightly lowered as the chiral chemical potential is increased, and the transition itself becomes milder. Furthermore, we study the chiral magnetic conductivity in different phases and find that it grows both in the perturbative weak-coupling regime and in the strongly coupled phase with broken chiral symmetry. In the strong coupling regime the chiral magnetic effect is saturated by vector-like bound states (vector mesons) with mixed transverse polarizations. General pattern of meson mixing in the presence of chiral imbalance is also considered. We discuss the relevance of our study for Weyl semimetals and strongly interacting QCD matter. Finally, we comment on the ambiguity of the regularization of the vacuum energy of Dirac fermions in the presence of chirality imbalance.
