description: We seek for self-similar solutions describing the time-dependent evolution of self-gravity systems with either spherical symmetry or axisymmetric disk geometry. By assuming self-similar variable $x\equiv r/at$ where $a$ is isothermal sound speed we find self-similar solutions extending from the initial instant $t=0$ to the final stage $t\to \infty$ using standard semi-analytical methods. Different types of solutions are constructed, which describe overall expansion or collapse, envelope expansion with core collapse (EECC), the formation of central rotationally supported quasi-equilibrium disk as well as shocks. Though infinitely many, these self-similarity solutions have similar asymptotic behaviors which may impose diagnosis on the velocity and density structures in astrophysical systems.

description: Using a generalized RPA-type theory we calculate the in-plane anisotropy of the magnetic excitations in hole-doped high-$T_c$ superconductors. Extending our earlier Fermi-liquid based studies on the resonance peak by inclusion of orthorhombicity we still find two-dimensional spin excitations, however, being strongly anisotropic. This reflects the underlying anisotropy of the hopping matrix elements and of the resultant superconducting gap function. We compare our calculations with new experimental data on {\it fully untwinned} ${YBa}_2{Cu}_3{O}_{6.85}$ and find good agreement. Our results are in contrast to earlier interpretations on the in-plane anisotropy in terms of stripes (H. Mook {\it et al.}, Nature {\bf 404}, 729 (2000)), but reveal a conventional solution to this important problem.

description: Multi-messenger astronomy has experienced an explosive development in the past few years. While not being a particularly young field, it has recently attracted a lot of attention by several major discoveries and unprecedented observation campaigns covering the entity of the electromagnetic spectrum as well as observations of cosmic rays, neutrinos, and gravitational waves. The exploration of synergies is in full steam and requires close cooperation between different instruments. Here I give an overview over the subject of multi-messenger astronomy and its virtues compared to classical "single messenger" observations, present the recent break throughs of the field, and discuss some of its organisational and technical challenges.

description: Der Anteil einheimischer Ware ist bei Öko-Tafeläpfeln in den letzten Jahren weitgehend unverändert bei etwa 60% geblieben. Damit ist die Situation in diesem Marktsegment deutlich besser als in anderen Bio-Obst- und Gemüsemärkten, in denen von steigenden Importanteilen in Deutschland ausgegangen wird. Um die Erfolgsfaktoren herauszuarbeiten, wurden strukturierte Interviews mit ausgewählten Akteuren der Wertschöpfungskette für Öko-Äpfel durchgeführt. Es hat sich gezeigt, dass vor allem der hohe Organisationsgrad und eine weit reichende Kooperation auf Erzeuger- und Erfassungsebene einerseits und andererseits die hohe Präferenz für einheimische Ware auf der Abnehmerseite Erfolg bestimmend sind. Das dadurch erreichte relativ konstante Preisniveau gibt den Erzeugern eine hohe Planungssicherheit und ermöglicht Investitionstätigkeiten, die der Reduktion von Ernteschwankungen und der Qualitätssteigerung dienen. Hierdurch erreicht der deutsche Öko-Apfel-Anbau eine große Verlässlichkeit als Vertragspartner für den deutschen Lebensmitteleinzelhandel.

description: Semiconductor-superconductor hybrid systems have outstanding potential for emerging high-performance nanoelectronics and quantum devices. However, critical to their successful application is the fabrication of high-quality and reproducible semiconductor-superconductor interfaces. Here, we realize and measure axial Al-Ge-Al nanowire heterostructures with atomically precise interfaces, enwrapped by an ultrathin epitaxial Si layer further denoted as Al-Ge/Si-Al nanowire heterostructures. The heterostructures were synthesized by a thermally induced exchange reaction of single-crystalline Ge/Si core/shell nanowires and lithographically defined Al contact pads. Applying this heterostructure formation scheme enables self-aligned quasi one-dimensional crystalline Al leads contacting ultrascaled Ge/Si segments with contact transparencies greater than 96%. Integration into back-gated field-effect devices and continuous scaling beyond lithographic limitations allows us to exploit the full potential of the highly transparent contacts to the 1D hole gas at the Ge-Si interface. This leads to the observation of ballistic transport as well as quantum confinement effects up to temperatures of 150 K. Low-temperature measurements reveal proximity-induced superconductivity in the Ge/Si core/shell nanowires. The realization of a Josephson field-effect transistor allows us to study the subgap structure caused by multiple Andreev reflections. Most importantly, the absence of a quantum dot regime indicates a hard superconducting gap originating from the highly transparent contacts to the 1D hole gas, which is potentially interesting for the study of Majorana zero modes. Moreover, underlining the importance of the proposed thermally induced Al-Ge/Si-Al heterostructure formation technique, our system could contribute to the development of key components of quantum computing such as gatemon or transmon qubits

Examining the quality of smoking cessation interventions available through the internet
Creators: name: Murphy, Caroline Cathrine
Publisher: name: University of British Columbia
Year: 2009

description: Background: The Internet promises to be an effective vehicle for widespread delivery of Web-assisted tobacco use cessation interventions. Little is known regarding the quality of information available or the usefulness of search tools, such as gateways, in enabling consumers access to accurate and credible cessation information. The purpose of the study was to describe the quality of online tobacco use cessation information available through the World Wide Web (WWW), to compare content of websites retrieved through different search tools, and determine the relationship between standard criteria and evidence-based criteria for smoking cessation interventions available through the Internet. Methods: Web sites purporting to provide self-help smoking cessation information were identified using three search tools; 1) search engine (google.com), 2) private gateway (allhealthnet.com), and 3) public gateway (canadian-health-network.ca, healthfinder.gov). Two independent reviewers rated sites using a 34-item checklist, designed to measure the presence of standard criteria for health information and evidence-based information for treating tobacco use; web site scores were calculated to judge quality of information and conduct analyses. A l l sites were selected and reviewed between February and April, 2004. Results: 120 sites were evaluated; the mean total quality score was 0.57 (range = 0.09 to 0.92). Mean total scores differed significantly between search tools (p = 0.02); post-hoc comparisons (Bonferonni correction) did not detect a difference in total quality scores between the three search tools. Linear regression analysis demonstrated that evidence-based score was a significant (p < 0.1) predictor of standard score, with a coefficient of determination of 0.26. Discussion: The type and content of tobacco use cessation information available is extremely variable, and is not dependent on the search tool used to access the web site. Findings question the utility and effectiveness of standard criteria to measure informational content, and highlight the importance of research into the effectiveness of Web-assisted tobacco use cessation interventions, and developing policies to guide consumers to useful information.

description: The LOw-Frequency ARray (LOFAR) has recently conducted a survey (LOFAR Tied-Array All-sky Survey; LOTAAS) for pulsars in the Northern hemisphere that resulted in discoveries of 73 new pulsars. For the purpose of studying the properties of these pulsars, we search for their $γ$-ray counterparts using the all-sky survey data obtained with the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope (Fermi).We analyze the LAT data for 70 LOTAAS pulsars (excluding two millisecond pulsars and one with the longest known spin period of 23.5s). We find one candidate counterpart to PSRJ1017$+$30, which should be searched for the $γ$-ray pulsation signal once its timing solution is available. For other LOTAAS pulsars, we derive their 0.3--500GeV flux upper limits. In order to compare the LOTAAS pulsars with the known $γ$-ray pulsars, we also derive the 0.3--500GeV $γ$-ray fluxes for 112 of the latter contained in the Fermi LAT fourth source catalog.Based on the properties of the $γ$-ray pulsars, we derive upper limits on the spin-down luminosities of the LOTAAS pulsars. The upper limits are not very constraining but help suggest that most of the LOTAAS pulsars probably have $< 10^{33}$erg s$^{-1}$ spin-down luminosities and are not expected to be detectable with Fermi LAT.

description: Isolated neutron stars are seen in x-rays through their nonthermal and/or surface thermal emissions. XMM-Newton observations of the Geminga pulsar show a 43 electron volt spectrum from the whole neutron star surface, as well as a power-law component above 2 kiloelectron volts. In addition, we have detected a hot (170 electron volts) thermal emission from an 60-meter-radius spot on the pulsar s surface. Such a thermal emission, only visible at selected phase intervals, may be coming from polar hot spot(s), long thought to exist as a result of heating from magnetospheric accelerated particles. It may provide the missing link between the x-ray and gamma-ray emission of the pulsar.

Channel-Independent and Sensor-Independent Stimulus Representations

description: This paper shows how a machine, which observes stimuli through an uncharacterized, uncalibrated channel and sensor, can glean machine-independent information (i.e., channel- and sensor-independent information) about the stimuli. First, we demonstrate that a machine defines a specific coordinate system on the stimulus state space, with the nature of that coordinate system depending on the device's channel and sensor. Thus, machines with different channels and sensors "see" the same stimulus trajectory through state space, but in different machine-specific coordinate systems. For a large variety of physical stimuli, statistical properties of that trajectory endow the stimulus configuration space with differential geometric structure (a metric and parallel transfer procedure), which can then be used to represent relative stimulus configurations in a coordinate-system-independent manner (and, therefore, in a channel- and sensor-independent manner). The resulting description is an "inner" property of the stimulus time series in the sense that it does not depend on extrinsic factors like the observer's choice of a coordinate system in which the stimulus is viewed (i.e., the observer's choice of channel and sensor). This methodology is illustrated with analytic examples and with a numerically simulated experiment. In an intelligent sensory device, this kind of representation "engine" could function as a "front-end" that passes channel/sensor-independent stimulus representations to a pattern recognition module. After a pattern recognizer has been trained in one of these devices, it could be used without change in other devices having different channels and sensors.
description: The results of a numerically simulated experiment, which illustrates the proposed method, have been added to the version submitted on October 27, 2004.

On the saturation of corotation resonances: a numerical study

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: [Abridged] The torque exerted by an external potential on a two-dimensional gaseous disk at non-co-orbital corotation resonances is studied by means of numerical simulations. The degree of saturation of these resonances is important in determining whether an eccentric giant planet embedded in a protoplanetary disk experiences an eccentricity excitation or damping. We perform calculations restricted to one or two resonances to investigate the properties of two neighboring corotation resonances, as well as the properties of a corotation resonance that overlaps a Lindblad resonance. We find that these properties hardly differ from the case of an isolated corotation resonance. In particular, although the torque of two neighboring corotation resonances may differ from the sum of the torques of the corresponding resonances considered as isolated, it never exceeds the sum of the fully unsaturated isolated corotation resonances, and it saturates in a fashion similar to an isolated resonance. Similarly, the presence of an underlying Lindblad resonance hardly affects the corotation torque, even if that resonance implies a torque strong enough to significantly redistribute the azimuthally averaged surface density profile, in which case the corotation torque scales with the resulting vortensity gradient. This set of numerical experiments thus essentially validates previous analytic studies. As a side result, we show that corotation libration islands misrepresented by a mesh of too low resolution can lead to a strongly overestimated corotation torque. This may be an explanation why the eccentricity of embedded Jupiter-sized planets was never observed to undergo an excitation in the numerical simulations performed so far.

description: The coherent flow of a Bose-Einstein condensate through a quantum dot in a magnetic waveguide is studied. By the numerical integration of the time-dependent Gross-Pitaevskii equation in presence of a source term, we simulate the propagation process of the condensate through a double barrier potential in the waveguide. We find that resonant transport is suppressed in interaction-induced regimes of bistability, where multiple scattering states exist at the same chemical potential and the same incident current. We demonstrate, however, that a temporal control of the external potential can be used to circumvent this limitation and to obtain enhanced transmission near the resonance on experimentally realistic time scales.

description: We present the novel wide & deep neural network GalaxyNet, which connects the properties of galaxies and dark matter haloes, and is directly trained on observed galaxy statistics using reinforcement learning. The most important halo properties to predict stellar mass and star formation rate (SFR) are halo mass, growth rate, and scale factor at the time the mass peaks, which results from a feature importance analysis with random forests. We train different models with supervised learning to find the optimal network architecture. GalaxyNet is then trained with a reinforcement learning approach: for a fixed set of weights and biases, we compute the galaxy properties for all haloes and then derive mock statistics (stellar mass functions, cosmic and specific SFRs, quenched fractions, and clustering). Comparing these statistics to observations we get the model loss, which is minimised with particle swarm optimisation. GalaxyNet reproduces the observed data very accurately ($χ_\mathrm{red}=1.05$), and predicts a stellar-to-halo mass relation with a lower normalisation and shallower low-mass slope at high redshift than empirical models. We find that at low mass, the galaxies with the highest SFRs are satellites, although most satellites are quenched. The normalisation of the instantaneous conversion efficiency increases with redshift, but stays constant above $z\gtrsim0.7$. Finally, we use GalaxyNet to populate a cosmic volume of $(5.9~\mathrm{Gpc})^3$ with galaxies and predict the BAO signal, the bias, and the clustering of active and passive galaxies up to $z=4$, which can be tested with next-generation surveys, such as LSST and Euclid.

description: Die Erschließung neuer Absatzkanäle im konventionellen Lebensmitteleinzelhandel hat ein rasantes Wachstum des Marktes für ökologische Lebensmittel ermöglicht. Neben positiven Effekten dieses Wachstums, wie einem erhöhten Absatz von Bio-Produkten und umfassenden Professionalisierungseffekten ist unternehmerisches Handeln heute auch in der Bio-Branche von steigendem Preisdruck sowie einer erhöhten Komplexität und Anonymität der Handelsbeziehungen geprägt. In diesem Zusammenhang wird diskutiert, inwiefern eine Rückbesinnung auf die Grundwerte des Ökologischen Landbaus notwendig ist – unter anderem dem Prinzip der Fairness (IFOAM, 2005). Geht man davon aus, dass ethische Aspekte, wie artgerechte Tierhaltung, regionale Erzeugung und faire Erzeugerpreise wichtige Motive für den Kauf von Öko-Produkten darstellen (ZANDER & HAMM, 2010), ist eine ethische Untermauerung von „Bio-Marken“ im Sinne der Produktdifferenzierung von Bio- Waren wichtig. Vor diesem Hintergrund beschäftigen sich Verbände und einige Unternehmen des Ökologischen Landbaus mit der Thematik fairer Handelsbeziehungen im globalen Norden (SCHÄFER & KRÖGER, 2011). Bisher besteht jedoch keine Einigkeit über Begrifflichkeiten und Konzepte. Ziel dieses Beitrages ist es, nach einer begrifflichen Eingrenzung fairer Handelsbeziehungen im globalen Norden unter dem Schlagwort „Domestic Fair Trade“ (DFT) eine konzeptionelle Einordung dieses Ansatzes in den sozio-ökonomischen Erklärungsrahmen ausgewählter markt- sowie ethisch-orientierter Theorien vorzunehmen.

description: We present here an information theoretic study of Gaussian collective attacks on the continuous variable key distribution protocols based on Gaussian modulation of coherent states. These attacks, overlooked in previous security studies, give a finite advantage to the eavesdropper in the experimentally relevant lossy channel, but are not powerful enough to reduce the range of the reverse reconciliation protocols. Secret key rates are given for the ideal case where Bob performs optimal collective measurements, as well as for the realistic cases where he performs homodyne or heterodyne measurements. We also apply the generic security proof of Christiandl et. al. [quant-ph/0402131] to obtain unconditionally secure rates for these protocols.

description: The membership problem asks to maintain a set $S\subseteq[u]$, supporting insertions and membership queries, i.e., testing if a given element is in the set. A data structure that computes exact answers is called a dictionary. When a (small) false positive rate $ε$ is allowed, the data structure is called a filter. The space usages of the standard dictionaries or filters usually depend on the upper bound on the size of $S$, while the actual set can be much smaller. Pagh, Segev and Wieder (FOCS'13) were the first to study filters with varying space usage based on the current $|S|$. They showed in order to match the space with the current set size $n=|S|$, any filter data structure must use $(1-o(1))n(\log(1/ε)+(1-O(ε))\log\log n)$ bits, in contrast to the well-known lower bound of $N\log(1/ε)$ bits, where $N$ is an upper bound on $|S|$. They also presented a data structure with almost optimal space of $(1+o(1))n(\log(1/ε)+O(\log\log n))$ bits provided that $n>u^{0.001}$, with expected amortized constant insertion time and worst-case constant lookup time. In this work, we present a filter data structure with improvements in two aspects: - it has constant worst-case time for all insertions and lookups with high probability; - it uses space $(1+o(1))n(\log (1/ε)+\log\log n)$ bits when $n>u^{0.001}$, achieving optimal leading constant for all $ε=o(1)$. We also present a dictionary that uses $(1+o(1))n\log(u/n)$ bits of space, matching the optimal space in terms of the current size, and performs all operations in constant time with high probability.

description: Ernest James Frude fought with the 1/4th Hampshire Regiment in Mesopotamia from 1914. He was injured in the knee, and was sent to recuperate in England and Ireland while the Hampshires went to India. He was then assigned to the 1st Battalion, Somerset Light Infantry. He was sent to the Western Front, where he was eventually killed by an explosive shell on the 14th April 1918 near Ploegsteert in Belgium. He has no known grave and is remembered on the Memorial to the Missing in Ploegsteert, Basingstoke War Memorial Park and in St Michael's Church, Basingstoke.

description: Light fields with spatially varying backgrounds can modulate cosmic preheating, and imprint the nonlinear effects of preheating dynamics at tiny scales on large scale fluctuations. This provides us a unique probe into the preheating era which we dub the "cosmic microscope.'' We identify a distinctive effect of preheating on scalar perturbations that turns the Gaussian primordial fluctuations of a light scalar field into square waves, like a diode. The effect manifests itself as local non-Gaussianity. We present a model, "modulated partial preheating," where this nonlinear effect is consistent with current observations and can be reached by near future cosmic probes.

description: We present improved simulations of three-dimensional self avoiding walks with one end attached to an impenetrable surface on the simple cubic lattice. This surface can either be a-thermal, having thus only an entropic effect, or attractive. In the latter case we concentrate on the adsorption transition, We find clear evidence for the cross-over exponent to be smaller than 1/2, in contrast to all previous simulations but in agreement with a re-summed field theoretic $ε$-expansion. Since we use the pruned-enriched Rosenbluth method (PERM) which allows very precise estimates of the partition sum itself, we also obtain improved estimates for all entropic critical exponents.

description: Security bounds for key distribution protocols using coherent and squeezed states and homodyne measurements are presented. These bounds refer to (i) general attacks and (ii) collective attacks where Eve interacts individually with the sent states, but delays her measurement until the end of the reconciliation process. For the case of a lossy line and coherent states, it is first proven that a secure key distribution is possible up to 1.9 dB of losses. For the second scenario, the security bounds are the same as for the completely incoherent attack.

description: Vor dem Hintergrund eines sinkenden Schulmilchkonsums in Deutschland stellt sich generell die Frage, welche Faktoren für die Kaufentscheidung von Schulmilch wichtig sind und, ob unterschiedliche Konsummuster für einzelne Gruppen existieren. Dieser Beitrag erweitert bestehende ökonometrische Erklärungsansätze um Schüler- und Haushaltscharakteristika. Dazu werden auf der Grundlage der Discrete Choice-Theorie zwei Konsummuster, die Gruppe der Schulmilchbesteller und die Gruppe der Nicht-Besteller, betrachtet. Mit Hilfe eines Logit-Modells werden Einflussfaktoren analysiert, die über das Konsummuster entscheiden. Als wichtige Faktoren kristallisieren sich die befürwortenden und ablehnenden Einstellungen der Schulkinder und ihrer Eltern gegenüber Milch und Schulmilch heraus. Weiterhin variiert die Chance Schulmilch zu bestellen mit dem Geschlecht, dem Alter und dem Migrationshintergrund der Schulkinder. Schulkinder aus Haushalten mit niedrigen Nettoeinkommen weisen eine höhere Chance auf, keine Schulmilch zu bestellen als Kinder aus Haushalten mit höherem Einkommen. Das Produktsortiment beeinflusst ebenfalls die Bestellwahrscheinlichkeit. Ist dieses vielfältig, erhöht sie sich, werden hingegen auch andere Getränke angeboten, sinkt sie. School milk consumption is currently declining in Germany. To analyse the reasons for this development existing econometric models are extended by characteristics of pupils and their households. Based on discrete choice theory, a logit model is applied investigating factors which distinguish school milk buyers from non-buyers. Important factors are the attitude of pupils and children towards milk and school milk as well as nutritional behavior at school. Buying behavior varies with age, sex and the migration background of pupils. Girls, pupils with migration background and older pupils show a higher chance of being in the non-buyer group. The same holds for children who belong to a low-income household. At school a higher variety of school milk products increases the chance for buying school milk while offering non-milk beverages reduces it.

description: William Ernest Paskins (contributor's grandfather) was sent to the Dardanelles during the war. At some point, he acquired this wooden model of a tank. It is not known whether the model was made by himself or whether he purchased it from another soldier, but it is believed to be a piece of trench art. The slot in the turret suggests it was intended to be used as a money bank. Paskins never talked about the war itself, but his family knew it had given him the opportunity to travel and see the world.

description: We show that a general purpose clusterization algorithm, Deterministic Annealing, can be adapted to the problem of jet identification in particle production by high energy collisions. In particular we consider the problem of jet searching in events generated at hadronic colliders. Deterministic Annealing is able to reproduce the results obtained by traditional jet algorithms and to exhibit a higher degree of flexibility.

description: Subsistence-based and natural resource-dependent societies are especially vulnerable to climate change. In such contexts, food security needs to be strengthened by investing in the adaptability of food systems. This paper looks into the role of agrobiodiversity conservation for food security in the face of climate change. It identifies agrobiodiversity as a key public good that delivers necessary services for human wellbeing. We argue that the public values provided by agrobiodiversity conservation need to be demonstrated and captured. We offer an economic perspective of this challenge and highlight ways of capturing at least a subset of the public values of agrobiodiversity to help adapt to and reduce the vulnerability of subsistence based economies to climate change
Octet, decuplet and antidecuplet magnetic moments in the chiral quark soliton model revisited

description: We reanalyse the magnetic moments of the baryon octet, decuplet, and antidecuplet within the framework of the chiral quark-soliton model, with SU(3) symmetry breaking taken into account. We consider the contributions of the mixing of higher representations to the magnetic moment operator arising from the SU(3) symmetry breaking. Dynamical parameters of the model are fixed by experimental data for the magnetic moments of the baryon octet and from the masses of the octet, decuplet and of $Θ^{+}$. The magnetic moment of $Θ^{+}$ depends rather strongly on the pion-nucleon sigma term and reads $-1.19 {\rm n.m.}$ to $-0.33 {\rm n.m.}$ for $Σ_{πN} = 45$ and 75 MeV respectively. The recently reported mass of $Ξ^{--}_{\bar{10}}(1862)$ is compatible with $Σ_{πN} = 73$ MeV. As a byproduct the strange magnetic moment of the nucleon is obtained with a value of $μ^{(s)}_N =+0.39$ n.m.
