Untersuchung der Auftauschicht über Dauerfrost in Spitzbergen
Creators: name: Stäblein, Gerhard
Publisher: name: Geozon Science Media
Year: 1970

description: Entlang von zwei Meßprofilen in W- und SE-Spitzbergen wurde die Entwicklung der Auftauschicht in Korrelation zu Frostmusterformen und Standortbedingungen gemessen. Die Ergebnisse werden mit bisherigen Beobachtungen aus Spitzbergen verglichen. Die Auftautiefen für Standorte geringer Höhe ü. NN sind mit Werten von rd. 30—80 cm in W- und SE-Spitzbergen nur wenig unterschiedlich. Die lokalen Standortunterschiede durch Vegetationsbedeckung und Frostmuster bedingen eine stärkere Schwankung der Auftautiefe als die überregionalen Unterschiede. Es entsteht dadurch ein „basales Auftaurelief", das das kleingliedrige Oberflächenrelief der Frostmusterformen verstärkt und gleichsinnig abbildet, und auch am Ende der sommerlichen Auftauperiode nicht ganz ausgeglichen ist.

--------------------------------------------------------Abstract-Owing to small size, sensing capabilities and autonomous nature, the Unmanned Air Vehicles (UAVs) have enormous applications in various areas e.g., remote sensing, navigation, archaeology, journalism, environmental science, and agriculture. However, the un-monitored deployment of UAVs called the amateur drones (AmDr) can lead to serious security threats and risk to human life and infrastructure. Therefore, timely detection of the AmDr is essential for the protection and security of sensitive organizations, human life and other vital infrastructure. AmDrs can be detected using different techniques based on sound, video, thermal, and radio frequencies. However, the performance of these techniques is limited in sever atmospheric conditions. In this paper, we propose an efficient un-supervise machine learning approach of independent component analysis (ICA) to detect various acoustic signals i.e., sounds of bird, airplanes, thunderstorm, rain, wind and the UAVs in practical scenario. After unmixing the signals, the features like Mel Frequency Cepstral Coefficients (MFCC), the power spectral density (PSD) and the Root Mean Square Value (RMS) of the PSD are extracted by using ICA. The PSD and the RMS of PSD signals are extracted by first passing the signals from octave band filter banks. Based on the above features the signals are classified using Support Vector Machines (SVM) and K Nearest Neighbor (KNN) to detect the presence or absence of AmDr. Unique feature of the proposed technique is the detection of a single or multiple AmDrs at a time in the presence of multiple acoustic interfering signals. The proposed technique is verified through extensive simulations and it is observed that the RMS values of PSD with KNN performs better than the MFCC with KNN and SVM.

description: Durch die fast gleichzeitig geglückten Funde von sehr altertümlichen Steinwerkzeugen im Neckargebiet (durch A. Rust) und im Donaugebiet (durch H. Mohr und H. Küpper) ist die Frage der Existenz einer bodenständigen Industrie zur Zeit des Heidelberger Vormenschen (oder eines Vorgängers) in Mitteleuropa bejaht worden. Die zur Beschreibung gelangenden Geräte wurden aus dem höchsten und jetzt als basalpleistozän erkannten Schotterkomplex im Raum von Wien (Laaer Berg - Wiener Berg) aufgesammelt. Es ergaben sich klare Beziehungen (sowohl in typologischer als in schlagtechnischer Hinsicht) zum Gerätebestand der Heidelberger Stufe im Neckargebiet. Nach M. Mottl ist die Industrie der Laaer Berg-Schotter im Wesentlichen als eine Geröll-Abschlag-Industrie mit starker Betonung der Nasenschaberformen zu bezeichnen. Die - spärlichen - Wirbeltierfunde aus den Schottern sprechen eindeutig für die basale Stellung des Schotterkomplexes innerhalb des pleistozänen Systems. Anknüpfungspunkte, die eine Verbindung zur Faustkeilentwicklung herstellen würden, konnten nicht nachgewiesen werden.

description: The use of network based approaches to model and analyse large datasets is currently a growing research field. For instance in biology and medicine, networks are used to model interactions among biological molecules as well as relations among patients. Similarly, data coming from social networks can be trivially modelled by using graphs. More recently, the use of dual networks gained the attention of researchers. A dual network model uses a pair of graphs to model a scenario in which one of the two graphs is usually unweighted (a network representing physical associations among nodes) while the other one is edge-weighted (a network representing conceptual associations among nodes). In this paper we focus on the problem of finding the Densest Connected sub-graph (DCS) having the largest density in the conceptual network which is also connected in the physical network. The problem is relevant but also computationally hard, therefore the need for introducing of novel algorithms arises. We formalise the problem and then we map DCS into a graph alignment problem. Then we propose a possible solution. A set of experiments is also presented to support our approach.

description: We investigate the formation of dust grains in the ejecta of population III supernovae including pair--instability supernovae, applying a theory of non-- steady state nucleation and grain growth. In the calculations, the time evolution of gas temperature in theejecta, which strongly affects the number density and size of newly formed grains, is calculated by solving the radiative transfer equation taking account of the energy deposition of radio active elements. Two extreme cases are considered for the mixing of elements in the ejecta; unmixed and uniformly mixed cases within the He--core. The results of calculations are summarized as the followings; in the unmixed ejecta, a variety of grain species condense, reflecting the difference of the elemental composition at the formation site in the ejecta, otherwise only oxide grains condense in the uniformly mixed ejecta. The average size of newly formed grains spans the range of three orders of magnitude, depending on the grain species and the formation condition, and the maximum radius is limited to less than 1 $μ$m, which does not depend on the progenitor mass. The size distribution function summed up over all grain species is approximated by a power--law formula whose index is -3.5 for the larger radius and -2.5 for the smaller one; the radius at the crossover point ranges from 0.004 to 0.1 $μ$m, depending on the model of supernovae. The fraction of mass locked into dust grains increases with increasing the progenitor mass; 2--5 % of the progenitor mass for core collapse supernovae and 15--30 % for pair--instability supernovae whose progenitor mass ranges from 140 to 260 $M_{\odot}$. Thus, if the very massive stars populate the first generation stars, a large amount of dust grains would be produced in the early universe.

description: With the increased interest in Terahertz applications and technologies there is a growing demand of new and improved transmitters. Spectrum analyzers are frequently used to characterise the spectral purity of transmitters. The Terahertz range state-of-the-art electronic spectrum analyzers are limited in terms of frequency coverage and are very expensive. In this article we present an alternative: photonic spectrum analysers based on the optical downconversion of continuous-wave lasers and photoconductive receivers. We compare the performance of two state-of-the-art photoconductive receivers in terms of their spectral roll-off and the displayed average noise level. We conclude with a comparison of the displayed average noise level of the photonic spectrum analyser to that of an electronic system employing extender modules.

description: Thirteen Katahdin (KT) sired male lambs were weaned at 60 days, placed in individual pens and fed on a mixture of commercial feed pellets (14% CP) and sugar cane bagasse. Each ram was randomly assigned to one of 4 groups. Animals in each group were reared to mean live-weights (± 1 kg) of 35 kg (Group 1), 40 kg (Group 2), 45 kg (Group 3) and 50 kg (Group 4). Average daily gain (ADG), feed conversion ratio (FCR), total feed cost per unit weight gained as well as dressing percentage was not significantly different (P>0.05) among groups. Based on these indices as well as the significantly (P<0.01) longer post weaning period required to attain the respective live-weights associated with the significantly greater (P< 0.01) deposition of belly fat and the relatively low increases in income over feed costs, it is recommended that KT crossbred lambs be slaughtered upon attaining a live-weight of 35 kg.

description: Feldbeobachtungen in den Altos de Cuchumatanes von Westguatemala erstreckten sich auf die SE-NW gerichteten tektonischen Täler von Llanos de San Miguel - Llano Ventura und Todos Santos, und das benachbarte Hochland mit Gipfeln um 3800 m. Als unmittelbarer Nachweis einer früheren Vereisung wurde talauf und nordwestlich der Llanos de Man Miguel in 3470—3600 m ein Komplex von vier Stirn- bzw. Seitenmoränen gefunden. Die Moränen enthalten Felsblöcke von 50—100 cm und haben eine typische Höhe um 20 m. Eine Fortsetzung der Seitenmoränen biegt vom Haupttal nordwärts. Das Hochtal Llanos de San Miguel -Llano Ventura scheint vor allem im Talabschnitt südöstlich eines Sattelpunktes im Längsprofil einen großen Eiskuchen enthalten zu haben, der wesentlich von der hohen Bergkette im SW aus genährt worden sein muß. Im Zusammenhang betrachtet ist es wahrscheinlich, daß einige abflußlose Wannen um 3700 m in dem südwestlich gelegenen Hochland sowie einige Talungen um 3500—3650 m in den Bergen südwestlich des Todos Santos-Tals auch Eis enthielten. Indessen herrschen Karstenerscheinungen vor, was eine zuverlässige Bestimmung gewisser möglicherweise glazigener Formen ausschließt; der Moränenkomplex bleibt damit als direkter Beleg. Die dazugehörige Gleichgewichtslinie des Eismassenhaushalts dürfte um 3650 m gelegen haben. Diese Höhenlage und die räumliche Abfolge der Moränen passen zu denen benachbarter Gebirgsgegenden der mesoamerikanischen Landbrücke.

description: Effective entrepreneurship depends upon numerous aspects. Of primary relevance is a devoted, skilled, innovative entrepreneur. The person who has the ideas, the power, and the vision to develop a new service is the cornerstone to any start-up. However the individual need to have all set accessibility to a variety of crucial resources in order to make the brand-new endeavor more than just an excellent concept. He or she requires developing a plan of action, a plan that will take the venture from the idea phase to a state of growth and also institutionalization. In the majority of instances, the business owner additionally needs to put together a group of skilled, seasoned individuals to help handle the new venture's procedures. Entrepreneurship likewise depends on accessibility to funding, whether it behuman, technological, or financial. In short, entrepreneurship is a procedure that includes prep work and the involvement of others in order to manipulate a chance for profit.

description: The Ophiuchus galaxy cluster exhibits a curious concave gas density discontinuity at the edge of its cool core. It was discovered in the Chandra X-ray image by Werner and collaborators, who considered a possibility of it being a boundary of an AGN-inflated bubble located outside the core, but discounted this possibility because it required much too powerful an AGN outburst. Using low-frequency (72-240 MHz) radio data from MWA GLEAM and GMRT, we found that the X-ray structure is, in fact, a giant cavity in the X-ray gas filled with diffuse radio emission with an extraordinarily steep radio spectrum. It thus appears to be a very aged fossil of the most powerful AGN outburst seen in any galaxy cluster ($pV\sim 5\times 10^{61}$ erg for this cavity). There is no apparent diametrically opposite counterpart either in X-ray or in the radio. It may have aged out of the observable radio band because of the cluster asymmetry. At present, the central AGN exhibits only a weak radio source, so it should have been much more powerful in the past to have produced such a bubble. The AGN is currently starved of accreting cool gas because the gas density peak is displaced by core sloshing. The sloshing itself could have been set off by this extraordinary explosion if it had occurred in an asymmetric gas core. This dinosaur may be an early example of a new class of sources to be uncovered by low-frequency surveys of galaxy clusters.

description: A transfer from a richer individual to a poorer one seems to be the most intuitive and straightforward way of reducing income inequality in a society. However, can such a transfer reduce the welfare of the society? We show that a rich-to-poor transfer can induce a response in the individuals’ behaviors which actually exacerbates, rather than reduces, income inequality as measured by the Gini index. We use this result as an input in assessing the social welfare consequence of the transfer. Measuring social welfare by Sen’s social welfare function, we show that the transfer reduces social welfare. These two results are possible even for individuals whose utility functions are relatively simple (namely, at most quadratic in all terms) and incorporate a distaste for low relative income. We first present the two results for a population of two individuals. We subsequently provide several generalizations. We show that our argument holds for a population of any size, and that the choice of utility functions which trigger this response is not singular - the results obtain for an open set of the space of admissible utility functions. In addition, we show that a rich-to-poor transfer can exacerbate inequality when we employ Lorenz-domination, and that it can decrease social welfare when we draw on any increasing, Schur-concave welfare function.

description: Transactions can be facilitated by mechanisms such as markets, contracts, and hierarchies. We treat the mechanisms as black boxes and depict the efficiency of each mechanism by the mean and variance of the output costs. The boundaries of livestock farms are measured by the percentage of homegrown feed in total feed requirement. A theoretical model is proposed which explains how farm boundaries are shaped by the efficiency of two alternative transaction-facilitating mechanisms: markets and hierarchies. Using tax file data from Ontario swine farms, this article analyzes the impact that mechanism efficiency has on farm boundaries. To identify the causal relationship, monthly CAD/USD exchange rates are used as the instrumental variable for corn prices in Ontario. The findings suggest that the boundaries of Ontario swine farms are not arbitrary, rather they are shaped by the relative efficiency of the mechanisms. It is estimated that if the average corn price were doubled, ceteris paribus, the average Ontario swine farmer would grow all required corn by themselves (i.e., the farm boundary is 100%). If the variance of corn prices were doubled, the average farm boundary would increase from 44% to 49.8%. The costs for doubling farm boundary are estimated to be C$9,841.
Nucleon pole contributions in $J/ψ\to N \bar{N} π$, $p \bar{p} η$, $p \bar{p} η^{\prime}$ and $p \bar{p} ω$ decays

description: Nucleon pole contributions in $J/ψ\to N \bar N π$, $p \bar p η$, $p \bar p η^{\prime}$ and $p \bar{p} ω$ decays are re-studied. Different contributions due to PS-PS and PS-PV couplings in the $π$-N interaction and the effects of $NNπ$ form factors are investigated in the $J/ψ\to N \bar N π$ decay channel. It is found that when the ratio of $|F_0| /|F_M|$ takes small value, without considering the $NNπ$ form factor, the difference between PS-PS and PS-PV couplings are negligible. However, when the $NNπ$ form factor is included, this difference is greatly enlarged. The resultant decay widths are sensitive to the form factors. As a conclusion, the nucleon-pole contribution as a background is important in the $J/ψ\to N\bar{N}π$ decay and must be accounted. In the $J/ψ\to N\bar{N}η$ and $N\bar{N}η'$ decays, its contribution is less than 0.1% of the data. In the $J/ψ\to N\bar{N}ω$ decay, it provides rather important contribution without considering form factors. But the contribution is suppressed greatly when adding the off-shell form factors. Comparing these results with data would help us to select a proper form factor for such kind of decay.

description: We put forth Physiologically Driven Storytelling, a new approach to interactive storytelling where narratives adaptively unfold based on the reader's physiological state. We first describe a taxonomy framing how physiological signals can be used to drive interactive systems both as input and output. We then propose applications to interactive storytelling and describe the implementation of a software tool to create Physiological Interactive Fiction (PIF). The results of an online study (N=140) provided guidelines towards augmenting the reading experience. PIF was then evaluated in a lab study (N=14) to determine how physiological signals can be used to infer a reader's state. Our results show that breathing, electrodermal activity, and eye tracking can help differentiate positive from negative tones, and monotonous from exciting events. This work demonstrates how PIF can support storytelling in creating engaging content and experience tailored to the reader. Moreover, it opens the space to future physiologically driven systems within broader application areas.

Probenaufbereitung und das Messen der 14C Konzentration sind wichtige Aspekte im Zusammenhang mit der Radiokohlenstoffdatierung. Gegenwärtige Fortschritte in der Probenaufbereitung erlauben ein besseres Verstehen lang bekannter Probleme (z.B. die Kontamination von Knochen) und haben zu verbesserten Chronologien geführt. In diesem Überblick werden verschiedene Aufbereitungstechniken für typische Probengattungen beschrieben. Der letzte Schritt beim Erstellen einer Chronologie ist die Kalibration der Radiokohlenstoffalter. Die gegenwärtige auf Baumringzeitreihen basierende Kalibrationskurve wird stetig über das Holozän und Spätglazial hinaus erweitert. Eine zuverlässige Kalibrationkurve für die letzten 50.000–55.000 Jahre ist von herausragender Bedeutung sowohl für die Archäologie als auch die Geowissenschaften. In den letzten Jahren haben zahlreiche Studien an der Erweiterung der Radiokohlenstoff-Kalibrationskurve (INTCAL working group) und an der Rekonstruktion des Paläo-Reservoireffekts in marinen Archiven gearbeitet.

description: Contrary to common belief, the current emitted by a contact embedded in a two-dimensional electron gas (2DEG) is quantized in the presence of electric and magnetic fields. This observation suggests a simple, clearly defined model for the quantum current through a Hall device that does not invoke disorder or interactions as the cause of the integer quantum Hall effect (QHE), but is based on a proper quantization of the classical electron drift motion. The theory yields a quantitative description of the breakdown of the QHE at high current densities that is in agreement with experimental data. Furthermore, several of its key points are in line with recent findings of experiments that address the dependency of the QHE on the 2DEG bias voltage, results that are not easily explained within the framework of conventional QHE models.

description: Satellite-based quantum cryptography has already been demonstrated using discrete variable technology. Nonetheless, there is great interest in using weak coherent pulses to perform quantum key distribution (QKD) in the continuous variable (CV) paradigm. In this work, we study the feasibility of performing coherent-state CV-QKD via the satellite-to-ground channel. We use numerical methods to simulate atmospheric turbulence and compare the results with ground-based experimental data so as to confirm the validity of our approach. We find the results obtained from the numerical simulations agree well with the experimental data and represent an improvement over the state-of-the-art analytical models. Using the simulation results we then derive QKD key rates and find that useful non-zero key rates can be found over a limited range of zenith angles. Determination of QKD key rates using experimentally validated simulations of low-zenith-angle atmospheric channels represents an important step towards proving the feasibility of real-world satellite-to-Earth CV-QKD.

REMARK
 Two subfamilies have been gathered in the Trigonidiidae, the Trigonidiinae and the Nemobiinae, on both morphological (Gorochov 1986b; Desutter 1987) and molecular grounds (Chintauan-Marquier et al. 2013, 2016), invalidating the long lasting classification of Nemobiinae with field crickets (Gryllidae, Gryllinae). The family and the two subfamilies present many synapomorphies that support their monophylies and relationships.

title: The life and prose works of Amelia Opie (1769-1853)
Creators: name: Jones, Clive
Publisher: name: The Open University

description: This thesis examines the life and prose works of Amelia Opie. It explores the moral and social ideology of the novels and tales, setting them in the context of Opie's own ideological development as she moves from the radicalism of the 1790s, through a period of intellectual and religious uncertainty to her conversion to Quakerism in 1825. It draws on a detailed analysis of all Opie's extant writing in prose, including a comprehensive survey of her letters. Biographical criticism has been rather unfashionable in recent years, though this is beginning to change. The argument put forward here is that only through detailed biographical case studies is it possible to understand the complex and shifting alignments and allegiances of the period 1790 to 1830. This has often been characterised as an era in which both society and literature were highly polarised, with a clear division between radicals and conservatives. Careful analysis of Opie's life and work reveals the difficulties involved in categorising her in either camp, and her case exemplifies the way in which this very limited, and limiting, perspective can misrepresent or oversimplify the position of individuals within this period. Opie's position was both complex at any given time, embodying elements of both radical and conservative thought, and developed and changed over time in response to public and private events. Attempts to see her as a radical, on the one hand, or conservative, on the other, are bound to distort the interpretation of her writings and the assessment of her wider significance as a writer. This thesis therefore aims to provide a new insight into the work of Amelia Opie and also to represent the importance and value of a biographically sensitive criticism to a full understanding of both individual writers and the periods in which they work. An appendix to the thesis provides an annotated register of approximately four hundred of her letters, giving details of their location.

Quartäre Klimaphasen und Subrosion als Faktoren der Bildung von Kies-Terrassen im südwestlichen Harzvorland
Creators: name: Ricken, Werner
Publisher: name: Geozon Science Media
Year: 1982

description: Aufbau und Verbreitung der Kieskörper der Harzflüsse Sieber und Oder werden beschrieben, sowie verschiedene Erosionsterrassen ohne eigenen Kieskörper. Das Alter der Kiese und der Erosionsstufen kann mit den sich teilweise verzahnenden und überlagernden Lössen und deren Böden und auf biostratigraphischem Wege bestimmt bzw. eingeengt werden. Hierbei ergeben sich folgende Alter: Oberterrasse mindestens Elster, Ältere Mittelterrasse mindestens Drenthe, Mittelterrasse mindestens Warthe, Aue-Berg-Terrasse II Altweichsel, Ältere Niederterrasse Altweichsel bis Jungweichsel. Der Komplex der Weichsel-zeitlichen Kieskörper setzt sich in Subrosionsgebieten aus einer ersten bedeutenden Akkumulation im Altweichsel (Aue-Berg-Terrasse II und unterer Kieskörper der Älteren Niederterrasse) und neben mehreren kleineren Erosions- und Akkumulationsphasen aus einem Kieskörper der Jungweichsel-Zeit zusammen (oberer Kieskörper der Älteren Niederterrasse). Aus der Verzahnung mit den Lössen und ihren Derivaten folgt, daß der größte Teil der Terrassen-Kiese im Untersuchungsgebiet unter feucht-kaltem Solifluktionsklima gebildet worden ist (Aue-Berg-Terrasse II, unterer Kieskörper der Älteren Niederterrasse, vielleicht auch Oberterrasse), jedoch hat es auch bedeutende Akkumulationen unter trocken-kalten Klimaverhältnissen gegeben (oberer Kieskörper der Älteren Niederterrasse, vermutlich auch Mittelterrasse). Erosionsphasen unter kaltem Klima — teilweise Tundrenklima — wurden festgestellt (Beginn von Mittel-, Jung-und Spätweichsel, vermutlich auch nach der Sedimentation der Älteren Mittelterrasse). Eine Bifurkation der Sieber nach Verlassen des Harzes ist für fast alle Akkumulationsphasen belegt. In den Eintiefungsphasen während des Eem-Interglazials und vermutlich auch vor der Akkumulation der Mittelterrasse wurde jedoch, wie auch heute, der konsequent verlaufende Sieberarm aufgegeben (Aue-Tal) und nur der Talabschnitt im Zechstein benutzt (Hördener Tal). Das Hördener Tal ist in den Interglazialen jeweils aufgrund von Subrosions- und Erosionsprozessen übertieft worden. Es gibt zwei Typen von fluviatil geprägten Subrosionssenken. Die subrosive Absenkung kann überwiegend synchron mit der Kiessedimentation verlaufen (synsedimentäre Subrosion), oder sie kann überwiegend zeitgleich mit der Fluß-Erosion wirken (synerosive Subrosion). Synsedimentäre Subrosion hat im Altweichsel im Pöhlder Becken die Bildung eines über 50 m mächtigen Kieslagers verursacht. Synerosive Subrosion hat im Eem-Interglazial, wie auch heute westlich von Herzberg, eine Ubertiefung des Siebertales ausgelöst. Im nachfolgenden Weichsel-Glazial ist dann in dem übertieften Talabschnitt der übernormal mächtige Kieskörper der Älteren Niederterrasse sedimentiert worden.

description: Five years ago a new acronym GLIMPSE was proposed in the International Food and Agribusiness Management Review to summarize the seven barriers faced by agriculture in its quest to feed the world, based on interviews of 25 agribusiness experts. Through an iterative, grounded theory methodology the original research that led to the GLIMPSE framework was validated, deepened and expanded. The new research made minor revisions to the original GLIMPSE, but confirmed it as an effective framework to explain to an interested public how agriculture can tackle the planet’s nutritional requirements if certain constraints are addressed. Specifically, international policy makers, governments, non-governmental organization, charities, industry organizations, integrated food companies and farmers often struggle to explain the complex challenges agribusiness faces, and in this respect the GLIMPSE framework allows all stakeholders to describe the main challenges agriculture faces on its journey to feed almost 10 billion people by 2050.

description: The ambient solar wind flows and fields influence the complex propagation dynamics of coronal mass ejections in the interplanetary medium and play an essential role in shaping Earth's space weather environment. A critical scientific goal in the space weather research and prediction community is to develop, implement and optimize numerical models for specifying the large-scale properties of solar wind conditions at the inner boundary of the heliospheric model domain. Here we present an adaptive prediction system that fuses information from in situ measurements of the solar wind into numerical models to better match the global solar wind model solutions near the Sun with prevailing physical conditions in the vicinity of Earth. In this way, we attempt to advance the predictive capabilities of well-established solar wind models for specifying solar wind speed, including the Wang-Sheeley-Arge (WSA) model. In particular, we use the Heliospheric Upwind eXtrapolation (HUX) model for mapping the solar wind solutions from the near-Sun environment to the vicinity of Earth. In addition, we present the newly developed Tunable HUX (THUX) model which solves the viscous form of the underlying Burgers equation. We perform a statistical analysis of the resulting solar wind predictions for the time 2006-2015. The proposed prediction scheme improves all the investigated coronal/heliospheric model combinations and produces better estimates of the solar wind state at Earth than our reference baseline model. We discuss why this is the case, and conclude that our findings have important implications for future practice in applied space weather research and prediction.

description: Muon pair production through the radiative return is of importance for a measurement of the hadronic production cross section in two ways: it provides an independent calibration and it may give rise to an important background for a measurement of the pion form factor. With this motivation the Monte Carlo event generator PHOKHARA is extended to include next-to-leading order radiative corrections to the reaction $e^+e^-\to μ^+μ^-γ$. Furthermore, virtual ISR corrections to FSR from pions are introduced, which extends the applicability of the generator into a new kinematical regime. Finally, the effect of photon vacuum polarization is introduced into this new version of the generator.

description: A Steiner quadruple system of order v is a 3-(v,4,1) design, and will be denoted SQS(v). Using the classification of finite 2-transitive permutation groups all SQS(v) with a flag-transitive automorphism group are completely classified, thus solving the "still open and longstanding problem of classifying all flag-transitive 3-(v,k,1) designs" for the smallest value of k. Moreover, a generalization of a result of H. Lueneburg (1965, Math. Z. 89, 82-90) is achieved.
