Shot-noise of quantum chaotic systems in the classical limit

description: Semiclassical methods can now explain many mesoscopic effects (shot-noise, conductance fluctuations, etc) in clean chaotic systems, such as chaotic quantum dots. In the deep classical limit (wavelength much less than system size) the Ehrenfest time (the time for a wavepacket to spread to a classical size) plays a crucial role, and random matrix theory (RMT) ceases to apply to the transport properties of open chaotic systems. Here we summarize some of our recent results for shot-noise (intrinsically quantum noise in the current through the system) in this deep classical limit. For systems with perfect coupling to the leads, we use a phase-space basis on the leads to show that the transmission eigenvalues are all 0 or 1 -- so transmission is noiseless [Whitney-Jacquod, Phys. Rev. Lett. 94, 116801 (2005), Jacquod-Whitney, Phys. Rev. B 73, 195115 (2006)]. For systems with tunnel-barriers on the leads we use trajectory-based semiclassics to extract universal (but non-RMT) shot-noise results for the classical regime [Whitney, Phys. Rev. B 75, 235404 (2007)].

Numerische Modellierung der Interaktionen zwischen Oberflächengewässern und dem Grundwasser mit Hilfe von geohydraulischen, isotopenhydrologischen und hydrochemischen Untersuchungen
Creators: name: Michel, Werner

description: Das Ziel ist, mit Hilfe natürlicher Tracer und hydraulischer Berechnungen die am Grundwasserfließgeschehen im quartären Porengrundwasserleiter des Argendeltas beteiligten Grundwasserkomponenten sowie die Interaktion der Oberflächengewässer mit dem Grundwasser eingehend qualitativ und quantitativ zu beschreiben. Als Tracer wurden das stabile Sauerstoff-18-Isotop und hydrochemische Inhaltsstoffe, die in der Argen eine deutliche Markierung gegenüber dem Grundwasser zeigen, verwendet. Die Verteilung der isotopenhydrologisch und hydrochemisch ermittelten Anteile von Argen-Uferfiltrat im Grundwasserleiter des Argendeltas wurde mit einem numerischen Grundwasserströmungs- und Transportmodell simuliert. Die Berechnungen erfolgten instationär. Die bisherige Nutzung erfolgt im westlichen Teil des Argendeltas durch einen Horizontalfilterbrunnen mit einer möglichen Förderrate von 150 l/s. Für eine neue Erschließung auf der östlichen Seite der Argen musste aufgrund der auch hier intensiv betriebenen landwirtschaftlichen Flächennutzung die räumliche und zeitliche Beeinflussung des Grundwassers durch Argen-Uferfiltratanteile genau erkundet werden. Zur Erstellung des konzeptionellen Modells wurde eine Quantifizierung der räumlich-zeitlichen Verteilung des Argen-Uferfiltrats durchgeführt. Das numerische Modell musste aufgrund der neuen geologischen Erkenntnisse dreidimensional aufgebaut werden, um die Anbindung der Argen an den Grundwasserleiter und den Einfluss oberflächennaher Grundwässer auf die geplante Erschließung des tieferen Aquiferbereiches besser beschreiben zu können. Das kalibrierte Grundwasserströmungsmodell bildete die Grundlage für die Prognoseberechnungen zur Erstellung eines Bewirtschaftungskonzeptes für das gesamte Grundwasservorkommen im Argendelta. Die Berechnungen der Fließzeiten und der 50-Tage-Linie als Grundlage für die Bemessung des notwendigen Wasserschutzgebietes für eine zukünftige Trinkwasseranlage war ebenfalls möglich. Die vorgestellten Untersuchungen zeigten, dass mit dem natürlichen Tracer Sauerstoff 18 und mit hydrochemischen Inhaltsstoffen bei einer ausreichenden Anzahl von Analysen die Interaktion zwischen Oberflächengewässern und Grundwasser räumlich und zeitlich sowohl qualitativ als auch quantitativ beschrieben werden kann.

description: The superfield formulation of type II Green-Schwarz superstring with n= (1,0) worldsheet supersymmetry is constructed. It is shown that the inclusion of the second spinor coordinate in the target superspase leads to the possibility of the reparametrization invariant description of the superstring in the absence of any field from the two dimensional supergravity multiplet. The twistor-like action of Chern-Simons type for bosonic string in D=3,4,6,10 is obtained from the component form of the superstring action.

researcher-driven support

description: While CSIRO's Research Data Service (RDS) has been promoting sound data management practices and the sharing of data, uptake has been inconsistent, and fallen largely to early adopters, those required by publishers or funders, and those with other motivations. Across CSIRO, data management awareness is limited to small pockets: large facilities have detailed requirements, but the approach is inconsistent. Meanwhile, the explosion in data science is driving a need for a holistic approach to upskilling researchers. Researchers from the Agriculture and Food (A&F) research unit called for support for developing better data skills and approached their executive for assistance, and the Ag & Food Data School was born. In consultation with the A&F Data School organisers, an activities-based RDM component using the Carpentries model was presented in April 2018. This material was collaboratively refined and presented in October 2018. Deep engagement has flowed from these sessions. CSIRO's Learning and Development unit are working with RDS team members to take this to an enterprise level initiative. Peer-to-peer learning has a great chance of success. Partnering with researchers helps support teams connect concepts with researchers' practice. Co-design training with engaged researchers, as collaboration is the key to improving data culture and practice.

description: Die Spalte im Hauptrogenstein von Herbolzheim (Steinbruch Behrle) in der Vorbergzone des nördlichen Breisgau/Südbaden, SW-Deutschland, wird nachuntersucht. Ihre Füllung besteht aus Gesteinsresten, die heute in der Umgebung nirgendwo mehr Übertage anstehen. Es wurden als Spaltenfüllung Gesteine vom Variansmergel, Macrocephalenoolith?, Callovientone und vom unteren Ancepsoolith nachgewiesen. Von den Callovientonen und dem Ancepsoolith glitten offensichtlich größere noch teilweise im Zusammenhang befindliche Gesteinsverbände in die Spalte hinein. So konnte für diesen Bereich ein kleines Profil rekonstruiert werden. Anhand von zahlreichen Ammonitenfunden konnten für diesen Abschnitt feinststratigraphische Altersdatierungen zumindest bis in den Bereich von Subzonen durchgeführt werden. Danach gehört der Übergang von den oberen Callovientonen zu dem untersten Ancepsoolith in den Grenzbereich Koenigi-/Calloviense-Zone (Unter-Callovium). Die für die Alterseinstufung relevanten Ammoniten werden näher vorgestellt.

Production of open-charm mesons in relativistic heavy-ion collisions

description: We present a theoretical framework to study open charm production in relativistic heavy-ion collisions. The coupling strength between the charm quarks and the QGP constituents, quantified by the spatial diffusion coefficient $2πTD_{s}$, is obtained by performing a phenomenological fit analysis to the lattice QCD calculations, resulting in $2πTD_{s}=const.$ (\textbf{Model-A}) and $2πTD_{s}=1.3 + (T/T_{c})^2$ (\textbf{Model-B}). We find that the relative azimuthal distribution of the initially back-to-back generated $c\bar{c}$ pairs presents a broadening behaviour, which is more pronounced for $c\bar{c}$ pairs with small initial $p_{\rm T}$, and when the Model-B approach is adopted. The competition between the initial drag and the subsequent collective effects tends to restrict the time dependence of charm quark $R_{\rm AA}$. Concerning the theoretical uncertainty on final D-meson nuclear modification, the nuclear shadowing and pp baseline components are dominat at high and low $p_{\rm T}$ ($p_{\rm T}\lesssim3~{\rm GeV/{\it c}}$), respectively. The measured D-meson $R_{\rm AA}(p_{\rm T})$ favors Model-A assumption for the diffusion coefficient both at RHIC and LHC, while their $v_{2}(p_{\rm T})$ prefer Model-B at moderate $p_{\rm T}$. These results confirm the necessity to consider the temperature- and/or momentum-dependence of $2πTD_{s}$ to describe well the D-meson $R_{\rm AA}$ and $v_{\rm 2}$ simultaneously.

description: In this work we investigate the dynamics of cosmological models with spherical topology containing up to 600 Schwarzschild black holes arranged in an irregular manner. We solve the field equations by tessellating the 3-sphere into eight identical cells, each having a single edge which is shared by all cells. The shared edge is enforced to be locally rotationally symmetric (LRS), thereby allowing for solving the dynamics to high accuracy along this edge. Each cell will then carry an identical (up to parity) configuration which can however have an arbitrarily random distribution. The dynamics of such models is compared to that of previous works on regularly distributed black holes as well as with the standard isotropic dust models of the FLRW type. The irregular models are shown to have richer dynamics than that of the regular models. The randomization of the distribution of the black holes is done both without bias and also with a certain clustering bias. The geometry of the initial configuration of our models is shown to be qualitatively different from the regular case in the way it approaches the isotropic model

description: An der Geschichte der chemischen Elemente werden – ohne strikt chronologische Darstellung – einige Aspekte der Chemiegeschichte aufgezeigt. Der Elementbegriff des Altertums weicht von dem der wissenschaftlichen Chemie stark ab. Von der Alchemie führt der Weg über die Entdeckung der chemischen Grundgesetze zur exakten Naturwissenschaft. Die Idee eines „natürlichen Systems“ mündete nach allerlei Umwegen im Periodensystem der chemischen Elemente. Ausgangspunkt für die weitere Entwicklung waren die Entdeckung des radioaktiven Zerfalls und der Röntgenstrahlung. Mittlerweile ist durch die künstliche Herstellung die Zahl der Elemente auf 118 gestiegen. Elemente haben auch in der Literatur, der Satire und Science Fiction ihren Platz gefunden. Die große Zahl ungültiger Namen lässt erkennen, dass der Weg der Wissenschaft nicht geradlinig war. Offen bleibt, wie viele weitere Elemente noch werden hergestellt werden können.

description: Web archives materialize and preserve captures of webpages that may or may not exist anymore. In addition to the great historic value, its meaning for data scientists is just as big, since these archives provide the web in a form that can be processed and engineered. Web Data Engineering refers to the task of transforming this dataset in a way that it is more useful for what should be achieved with it. The Internet Archive as the provider of the world's largest web archive recently invested new, additional resources in their web data engineering efforts to provide added value to their customers and partners. However, Web data features some very specific traits that raise new challenges to deal with when providing exclusive services based on the information contained in our holdings. Due to the vast data size and its temporal dimension, this often requires going beyond the pure application of existing workflows and spend some substantial work on researching and experimenting with novel methods and tools to accomplish a job more effectively as well as efficiently in terms of resources and time.

description: This project involves introducing Dandong 99 strawberries to the cool environment of the high - altitude (1800 meters) area in Zhaotong. By analyzing the fruit quality and gene expression of the same batch of Dandong 99 strawberries in both Dandong and Zhaotong, and comparing them with the quality and gene expression of Zhangji strawberries, a variety locally promoted in Zhaotong, we aim to analyze the molecular mechanism of the impact of high - altitude factors on strawberry varieties.

description: It is expected that the grid of the future differs from the current system by the increased integration of distributed generation, distributed storage, demand response, power electronics, and communications and sensing technologies. The consequence is that the physical structure of the system becomes significantly more distributed. The existing centralized control structure is not suitable any more to operate such a highly distributed system. This thesis is dedicated to providing a promising solution to a class of energy management problems in power systems with a high penetration of distributed resources. This class includes optimal dispatch problems such as optimal power flow, security constrained optimal dispatch, optimal power flow control and coordinated plug-in electric vehicles charging. Our fully distributed algorithm not only handles the computational complexity of the problem, but also provides a more practical solution for these problems in the emerging smart grid environment. This distributed framework is based on iteratively solving in a distributed fashion the first order optimality conditions associated with the optimization formulations. A multi-agent viewpoint of the power system is adopted, in which at each iteration, every network agent updates a few local variables through simple computations, and exchanges information with neighboring agents. Our proposed distributed solution is based on the consensus+innovations framework, in which the consensus term enforces agreement among agents while the innovations updates ensure that local constraints are satisfied.

description: We perform a timing analysis on RXTE data of the accreting millisecond pulsar XTE J1751-305 observed during the April 2002 outburst. After having corrected for Doppler effects on the pulse phases due to the orbital motion of the source, we performed a timing analysis on the phase delays, which gives, for the first time for this source, an estimate of the average spin frequency derivative = (3.7 +/- 1.0)E-13 Hz/s. We discuss the torque resulting from the spin-up of the neutron star deriving a dynamical estimate of the mass accretion rate and comparing it with the one obtained from X-ray flux. Constraints on the distance to the source are discussed, leading to a lower limit of \sim 6.7 kpc.

Aesthetics of the Sublime and Don McKay's Poetics of Deep Time
Creators: name: Northrup, Tina
Publisher: name: Canadian Literature
Year: 2016

description: Known as a bird poet par excellence, Don McKay’s ornithological fascination has received more scholarly attention to date than his poetry and criticism on geological themes. One consequence of this critical orientation is that a significant development in McKay’s ongoing critique of Romanticism has not yet been discussed in depth—namely, the shifting terms of his engagement with aesthetics of the sublime. Looking primarily at McKay’s most recent essay collection, The Shell of the Tortoise (2011), as well as select poems from Strike/Slip (2006), this essay explores how McKay’s geopoetic engagements with aesthetics of the sublime extend his idiosyncratic definitions of “wilderness” and “poetic attention.” Moreover, it argues that sustained attention to treatments of sublimity in McKay’s work will result in a more textured understanding of his phenomenological poetics.

description: Generic $U(1)^2$ 4-d black holes with unbroken $N=1$ supersymmetry are shown to tend to a Robinson-Bertotti type geometry with a linear dilaton and doubling of unbroken supersymmetries near the horizon. Purely magnetic dilatonic black holes, which have unbroken $N=2$ supersymmetry, behave near the horizon as a 2-d linear dilaton vacuum $\otimes \, S^2$. This geometry is invariant under 8 supersymmetries, i.e. half of the original $N=4$ supersymmetries are unbroken. The supersymmetric positivity bound, which requires the mass of the 4-d dilaton black holes to be greater than or equal to the central charge, corresponds to positivity of mass for a class of stringy 2-d black holes.

description: Ibuprofen (IBU) has been considered as one of emergent pharmaceutical contaminants in environments due to its occurrences in natural water bodies. Some reports suggested that the IBU was biodegradable but details about biodegradation pathways and functional microbial community were still not fully clear. This study was aimed to assess IBU biodegradation using three different activated sludges (i.e. H: hospital, M: municipal, and D: distillery) with foci on surmising degradation pathway based on UPLC/Q-ToF/MS (ultra-performance liquid chromatography quadrupole time of flight mass spectrometry) analyses and concluding microbial community according to high-throughput sequencing for partial 16S rRNA gene. Results showed that some IBU (∼5 mg/L) was able to be degraded only by sludges H and M during 2–5 days incubation under aerobic conditions. From LC/MS analysis of degradation byproducts, two major ring-opening precursors were identified in extracted ion chromatogram data. Ring-opening degradation pathways leading to the formation of low-molecular-weight carboxylic acids were elucidated. Additionally, the principal coordinate analyses using Fast UniFrac method for the partial 16S rRNA gene showed the microbial communities in the three sludges were significantly different but typically with high proportion of sequences matched gene fragments from Proteobacteria phylum. Some sequences with first matches with previously reported IBU degraders (i.e. Nocardia sp., Sphingomonas sp., and Variovorax sp.) were only found in the sludges H and M which showed capability for IBU biodegradation. These results demonstrated some functional microbes in activated sludges from hospital and municipal WWTPs had potential to break down IBU into smaller molecules.

description: The recent advancement of high-intensity lasers has made all-optical Compton scattering become a promising way to produce ultra-short brilliant $γ$-rays in an ultra-compact system. However, so far achieved Compton $γ$-ray sources are severely limited by low conversion efficiency (lower than $10^{-5}$) and spectral intensity ($\sim10^{4}$ ${\rm photons/0.1\%BW}$). Here we present a highly efficient gamma photon emitter obtained by irradiating a high-intensity laser pulse on a miniature plasma device consisting of a plasma lens and a plasma mirror. This concept exploits strong spatiotemporal laser-shaping process and high-charge electron acceleration process in the plasma lens, as well as an efficient nonlinear Compton scattering process enabled by the plasma mirror. Our particle-in-cell simulations demonstrate that in this novel scheme, brilliant $γ$-rays with very high conversion efficiency (higher than $10^{-2}$) and spectral intensity ($\sim10^{9}$ ${\rm photons/0.1\%BW}$) can be achieved by employing currently available petawatt-class lasers with intensity of $10^{21}$ ${\rm W/cm^2}$. Such efficient and intense $γ$-ray sources would find applications in wide-ranging areas.

A Portable Frontier: Two Gender-Divergent Navigations of Western Canada
Creators: name: Gunn, Julian L
Publisher: name: Canadian Literature
Year: 2016

description: Rae Spoon and Ivan Coyote, Canadian gender-retired and gender-divergent queer artists and performers, collaborators on the stage show and book Gender Failure, are profoundly engaged with the landscapes, human communities, and perspectives of Western Canada – for Coyote the Yukon as a psychic home and for Spoon the prairies as a problematic origin. Both also experience Vancouver as a location of queer identity and community (also often problematic). As touring artists, both have spent a great deal of time traversing the landscape of Western Canada. As of this writing, both artists have adopted the singular pronoun “they”. Trans* and gender-divergent people are often prohibited by social and even grammatical rules from “coming to rest” in collective space and in language. These artists have responded by repurposing and reinterpreting Western Canadian spaces, and especially the process of traversing these spaces, to express gender-divergent embodiments and narratives. In particular, they delineate the separation of bodily and social being enforced by the gendered prohibitions built into collective spaces, and the struggle to reconcile, or even to express, this division.

description: QCD radiative correction to Higgs $\rightarrow$ two photons decay rate is calculated. Below the threshold we found negligible correction, thus supporting results obtained earlier by Djouadi et all [7]. Above the threshold radiative correction appears to be large for both real and imaginary part of H $γγ$ vertex. This leads to radiative correction for $Γ$(H $\rightarrow γγ$) to be of order 20--100 percents at $m_{t}=150 GeV$. Possible applications of our results for Higgs search at Next Linear Colliders (NLC) are briefly discussed.

description: Ibuprofen (IBU) has been considered as one of emergent pharmaceutical contaminants in environments due to its occurrences in natural water bodies. Some reports suggested that the IBU was biodegradable but details about biodegradation pathways and functional microbial community were still not fully clear. This study was aimed to assess IBU biodegradation using three different activated sludges (i.e., H: hospital, M: municipal, and D: distillery) with foci on surmising degradation pathway based on UPLC/Q-ToF/MS (ultra-performance liquid chromatography quadrupole time of flight mass spectrometry) analyses and concluding microbial community according to high-throughput sequencing for partial 16S rRNA gene. Results showed that some IBU (∼5 mg/L) was able to be degraded only by sludges H and M during 2-5 days incubation under aerobic conditions. From LC/MS analysis of degradation byproducts, two major ring-opening precursors were identified in extracted ion chromatogram (EIC) data. Ring-opening degradation pathways leading to the formation of low-molecular-weight carboxylic acids were elucidated. Additionally, the principal coordinate analyses using Fast UniFrac method for the partial 16S rRNA gene showed the microbial communities in the three sludges were significantly different but typically with high proportion of sequences matched gene fragments from Proteobacteria phylum. Some sequences with first matches with previously-reported IBU degraders (i.e., Nocardia sp., Sphingomonas sp., and Variovorax sp.) were only found in the sludges H and M which showed capability for IBU biodegradation. These results demonstrated some functional microbes in activated sludges from hospital and municipal WWTPs had potential to break down IBU into smaller molecules.

description: We report electron spin resonance (ESR) measurements on a large-area silicon MOSFET. An ESR signal at g-factor 1.9999(1), and with a linewidth of 0.6 G, is observed and found to arise from two-dimensional (2D) electrons at the Si/SiO2 interface. The signal and its intensity show a pronounced dependence on applied gate voltage. At gate voltages below the threshold of the MOSFET, the signal is from weakly confined, isolated electrons as evidenced by the Curie-like temperature dependence of its intensity. The situation above threshold appears more complicated. These large-area MOSFETs provide the capability to controllably tune from insulating to conducting regimes by adjusting the gate voltage while monitoring the state of the 2D electron spins spectroscopically.

description: The present paper discusses the application of the recently proposed Augmented Lagrangian Alternating Direction Inexact Newton (ALADIN) method to non-convex AC Optimal Power Flow Problems (OPF) in a distributed fashion. In contrast to the often used Alternating Direction of Multipliers Method (ADMM), ALADIN guarantees locally quadratic convergence for AC OPF. Numerical results for 5 to 300 bus test cases indicate that ALADIN is able to outperform ADMM and to reduce the number of iterations by about one order of magnitude. We compare ALADIN to numerical results for ADMM documented in the literature. The improved convergence speed comes at the cost of increasing the communication effort per iteration. Therefore, we propose a variant of ALADIN that uses inexact Hessians to reduce communication. Additionally, we provide a detailed comparison of these ALADIN variants to ADMM from an algorithmic and communication perspective. Moreover, we prove that ALADIN converges locally at quadratic rate even for the relevant case of suboptimally solved local NLPs.

description: Combustion of fuels containing organosulfur compounds has resulted in the emission of sulfur oxides (SOx) into the atmosphere, therefore, causing serious environmental and health hazards. Herein, slightly distorted octahedral zig-zag 1D coordination polymer of copper(II) [Cu(4-mba)2(H2O)3] was synthesized by reacting copper sulfate pentahydrate with a carboxylate-containing ligand (H-4mba = 4-methoxybenzoic acid) and employed for sulfur compound uptake. The ligand coordinates to the copper(II) atom via two pairs of deprotonated ligating atoms (carboxylate oxygens) and two water molecules. Structural characterization also reveals that interplay of O–H···O, N–H···O, C-H···O and C–H···π interactions between lattice and coordinated water and ligands significantly contribute to the crystal packing leading to the formation and strengthening of three-dimensional supramolecular assembly. The complex, [Cu(4-mba)2(H2O)3], show potential for desulfurization of fuel with an observed adsorption capacity of 9.6 mg/g at 32°C for 6 h. DFT calculations further revealed a transfer of electron sulfur-containing compounds and the complex, [Cu(4-mba)2(H2O)3], thus leading to a stronger pi–pi interaction.
Zur Habitatdynamik des Magerrasen-Perlmutterfalters (Boloria dia Linnaeus, 1767) auf Sturmwurfflächen im zentralen Baden-Württemberg

description: Für ausgewählte Lichtungen der Naturräume Schönbuch, Obere Gäue und Neckarbecken, die im Dezember 1999 in Folge von Sturmwürfen des Orkans „Lothar” entstanden waren, werden Beobachtungen zum Auftreten des Magerrasen-Perlmutterfalters (Boloria dia Linnaeus, 1767) mitgeteilt. Zwischen 2001 und 2005 wurde die Art auf 18 von 38 untersuchten Lichtungen (47 %) nachgewiesen. Frühere Nachweise von Schlagfluren oder Sturmwurfflächen lagen aus dem Raum dagegen nicht vor. Im Zeitraum von 2006 bis 2011 konnte keines der neuen Vorkommen mehr bestätigt werden, obwohl die Art währenddessen auf Magerrasen der näheren Umgebung deutlich an Stetigkeit zunahm. Das Dispersionsvermögen von Boloria dia wird zwar von manchen Autoren als gering eingeschätzt. Gleichwohl belegen die Beobachtungen eine hohe Vagilität. Ursache des raschen Verschwindens der Art aus allen besiedelten Lichtungen sind Sukzessionsprozesse, die binnen weniger Jahre das zunächst neu entstandene Larvalhabitat wieder entwerteten. Letzteres wird auf Basis von Raupenfunden und Eiablagebeobachtungen kurz charakterisiert. Larvalhabitate dieser Falterart können durch natürliche Einflüsse wie Sturmwürfe kurzfristig entstehen. Ebenso rasch können sie durch anthropogene Entfernung von Gehölzbeständen entwickelt oder gefördert werden. Dies gilt gleichermaßen für Kahlhieb im Wald wie auch für Landschaftspflegemaßnahmen z. B. zur Offenhaltung von Kalkmagerrasen.

description: The component of the neoclassical electrostatic potential that is non-constant on the magnetic surface, that we denote by $\tildeφ$, can affect radial transport of highly charged impurities, and this has motivated its inclusion in some modern neoclassical codes. The number of neoclassical simulations in which $\tildeφ$ is calculated is still scarce, partly because they are usually demanding in terms of computational resources, especially at low collisionality. In this paper the size, the scaling with collisionality and with aspect ratio, and the structure of $\tildeφ$ on the magnetic surface are analytically derived in the $1/ν$, $\sqrtν$ and superbanana-plateau regimes of stellarators close to omnigeneity; i. e. stellarators that have been optimized for neoclassical transport. It is found that the largest $\tildeφ$ that the neoclassical equations admit scales linearly with the inverse aspect ratio and with the size of the deviation from omnigeneity. Using a model for a perturbed omnigeneous configuration, the analytical results are verified and illustrated with calculations by the code KNOSOS. The techniques, results and numerical tools employed in this paper can be applied to neoclassical transport problems in tokamaks with broken axisymmetry.

description: In städtischen Grünflächen von Tübingen wurden mittels Kescher- und Handfängen ausgewählte Käferarten erfasst. Die Artengemeinschaften von zwei- und mehrschürigen Flächen wurden miteinander verglichen. Insgesamt wurden in sechs Flächen 50 Käferarten nachgewiesen. Mehrmals pro Jahr gemähte Flächen wiesen eine geringere Käferartenzahl auf als zweischürige Flächen. Die höhere Artenzahl in zweischürigen Flächen bestätigt die Hypothese, dass dieser Lebensraum mehr Nahrungs- und Entwicklungshabitate sowie Versteckmöglichkeiten bieten kann als intensiv gepflegte Flächen. Hierauf deuten auch die statistischen Ähnlichkeitsvergleiche hin, die zeigen, dass das Artenspektrum von intensiv und extensiv gepflegten Vergleichsflächen relativ geringe Übereinstimmungen aufweist. Für bestimmte Käferarten lässt sich ein unmittelbarer Zusammenhang zwischen ihrem Auftreten und der jeweiligen Pflegevariante herstellen. Aufgrund der Ergebnisse wird empfohlen, auf städtischen Grünflächen nach Möglichkeit auf eine mehrfache Mahd zu verzichten und ein die Artenvielfalt förderndes extensives Pflegekonzept anzuwenden.

description: We analyze a supergravity theory coupled to a dilaton and superconformal matters in two dimensions. This theory is classically soluble and we find all the solutions appeared in Callan, Giddings, Harvey and Strominger's dilatonic gravity also satisfy the constraints and the equations of motion in this supersymmetric theory. We quantize this theory by following the procedure of Distler, Hlousek and Kawai. In the quantum action, the cosmological term is renormalized to vanish. As a result, any solution corresponding to classical black hole does not appear in the quantum theory, which should be compared with the non-supersymmetric case.

description: Free massless scalars have a shift symmetry. This is usually broken by gauge and Yukawa interactions, such that quantum corrections induce a quadratically divergent mass term. In the Standard Model this leads to the hierarchy problem of the electroweak theory, the question why the Higgs mass is so much smaller than the Planck mass. We present an example where a large scalar mass term is avoided by coupling the scalar to an infinite tower of massive states which are obtained from a six-dimensional theory compactified on a torus with magnetic flux. The series of divergent quantum corrections adds up to zero, and we show explicitly that the shift symmetry of the scalar is preserved in the effective four-dimensional theory despite the presence of gauge and Yukawa interaction terms.

description: Lattice simulations employing reweighting and Taylor expansion techniques have predicted a (μ,T)-phase diagram according to general expectations, with an analytic quark-hadron crossover at μ=0 turning into a first order transition at some critical chemical potential μ_E. By contrast, recent simulations using imgainary μfollowed by analytic continuation obtained a critical structure in the {m_{u,d},m_s,T,μ} parameter space favouring the absence of a critical point and first order line. I review the evidence for the latter scenario, arguing that the various raw data are not inconsistent with each other. Rather, the discrepancy appears when attempting to extract continuum results from the coarse (N_t=4) lattices simulated so far, and can be explained by cut-off effects. New (as yet unpublished) data are presented, which for N_f=3 and on N_t=4 confirm the scenario without a critical point. Moreover, simulations on finer N_t=6 lattices show that even if there is a critical point, continuum extrapolation moves it to significantly larger values of μ_E than anticipated on coarse lattices.
