description: Einleitung. Im Laufe der letzten Jahre gelangten einige fossile Vogelreste in die Sammlung des Naturwissenschaftlichen Vereins zu Regensburg. Bekanntlich gehören Versteinerungen aus der Klasse der Vögel zu den Seltenheiten und bilden daher stets höchst wertvolle Gegenstände: für die Regensburger Sammlung haben die neuen Stücke jedoch dadurch noch eine besondere Bedeutung, daß sie aus der Gegend von Regensburg selbst, von einer ganz in der Nähe der Stadt gelegenen Stätte, stammen; ihr Fundort ist die Tongrube zwischen Dechbetten und Prüfening (Tonwerk Mayer und Reinhard). Der dort zur Gewinnung aufgeschlossene Ton muß als der richtige Braunkohlenton der obermiocänen Tertiärschichten angesprochen werden. Er bat bereits schöne Schildkröten der Gattungen Trionyx und Clemmys (s. v. Ammon, Schildkröten aus dem Regensburger Braunkohlenton. Regensburg 1911, enthalten in der Separatbeilage zum 12. Jahresbericht des Naturwissenschaftlichen Vereins Regensburg für die Jahre 1907—1909), ein Krokodilskelett (Diplocynodon cf. yracilis Vaill.) und viele Säugetierknochen und -Zähne aus der Fauna des Dinotheriumsandes geliefert. Das Vorkommen der Vogelknochen giebt der berechtigten Hoffnung Raum, daß mit der Zeit durch die Vergrößerung der Tongrube noch weiteres, für ‘wissenschaftliche Zwecke wichtiges Material erbeutet werden könne.

description: We have measured the temperature (0.1 <= T <= 15 K) and magnetic field (0 <= B <= 12 T) dependences of longitudinal and Hall resistivities for the p-Ge_0.93Si_0.07/Ge multilayers with different Ge layer widths 10 <= d_w <= 38 nm and hole densities p_s = (1-5)10^11 cm^-2. Two models for the long-range random impurity potential (the model with randomly distributed charged centers located outside the conducting layer and the model of the system with a spacer) are used for evaluation of the impurity potential fluctuation characteristics: the random potential amplitude, nonlinear screening length in vicinity of integer filling factors nu = 1 and nu = 2 and the background density of state (DOS). The described models are suitable for explanation of the unusually high value of DOS at nu = 1 and nu = 2, in contrast to the short-range impurity potential models. For half-integer filling factors the linear temperature dependence of the effective QHE plateau-to-plateau transition width nu_0(T) is observed in contrast to scaling behavior for systems with short-range disorder. The finite T -> 0 width of QHE transitions may be due to an effective low temperature screening of smooth random potential owing to Coulomb repulsion of electrons.

description: Ad-hoc social networks (ASNETs) represent a special type of traditional ad-hoc network in which a user's social properties (such as the social connections and communications metadata as well as application data) are leveraged for offering enhanced services in a distributed infrastructureless environments. However, the wireless medium, due to limited bandwidth, can easily suffer from the problem of congestion when social metadata and application data are exchanged among nodes---a problem that is compounded by the fact that some nodes may act selfishly and not share its resources. While a number of congestion control schemes have been proposed for the traditional ad-hoc networks, there has been limited focus on incorporating social awareness into congestion control schemes. We revisit the existing traditional ad-hoc congestion control and data distribution protocols and motivate the need for embedding social awareness into these protocols to improve performance. We report that although some work is available in opportunistic network that uses socially-aware techniques to control the congestion issue, this area is largely unexplored and warrants more research attention. In this regards, we highlight the current research progress and identify multiple future directions of research.

description: We study the magnetic resonant x-ray scattering (RXS) spectra around the $K$ edge of Cu in KCuF$_3$ on the basis of an {\em ab initio} calculation. We use the full-potential linearlized augmented plane wave method in the LDA$+U$ scheme, and introduce the lattice distortion as inputs of the calculation. We obtain finite intensity on magnetic superlattice spots, about three orders of magnitude smaller than on orbital superlattice spots, by taking account of the spin-orbit interaction (SOI). No intensity appears without the SOI, indicating that the intensity arises not from the spin polarization but from the orbital polarization in $4p$ states. The present calculation reproduces well the experimental spectra as functions of photon energy and of azimuthal angle. We also calculate the RXS intensity on orbital superlattice spots. It is found that the intensity increases with increasing Jahn-Teller distortion. The spectra remain nearly the same in the nonmagnetic state given by the simple LDA, in which the orbital polarization in the 3d states is much smaller. This strongly suggests that the intensity on orbital spots is mainly controlled by the lattice distortion, not by the 3d orbital order itself.

description: A review is given of some well-known and some recent results for two- and three-dimensional (2D and 3D) solitons, with emphasis on states carrying embedded vorticity. Unlike typically stable 1D solitons, 2D and 3D ones are vulnerable to instabilities induced by the critical and supercritical collapse, respectively, in the 2D and 3D models with cubic focusing nonlinearity. Vortex solitons are subject to a still stronger splitting instability. For this reason, a central problem is looking for physical settings in which 2D and 3D solitons may be stabilized. The review addresses, first, two well-established topics, viz., the stabilization of vortex solitons by means of competing nonlinearities, or by trapping potentials (harmonic-oscillator and spatially-periodic ones). The former topic includes a new addition, viz., the prediction of robust quantum droplets. Two other topics outline new schemes elaborated for the creation of stable vortical solitons. One scheme relies on the use of spin-orbit coupling (SOC) in binary BEC, making it possible to predict stable 2D and 3D solitons, which couple or mix components with vorticities S=0 and (+/-)1 (semi-vortices (SVs) or mixed modes (MMs), respectively). In this system, the situation is different in the 2D and 3D geometries. In 2D, SOC helps to create a ground state (GS), represented by stable SV or MM solitons, whose norm falls below the threshold value at which the critical collapse sets in. In the 3D geometry, the supercritical collapse does not allow one to create a GS, but metastable solitons of the SV and MM types can be constructed. Another new scheme makes it possible to create stable 2D vortex-ring solitons with arbitrarily high S in a binary BEC with components coupled by microwave radiation. Some other topics are addressed too, such as vortex solitons in dissipative media and attempts to create vortex solitons in experiments.

Es war ein äusserst glücklicher Zufall, der mich in diesem Frühjahr nach Neapel führte und zwar schon am 23. März, also geraume Zeit vor dem Beginne der grossen Eruption. Die Tätigkeit des Vesuv war während der letzten Woche des März etwas gesteigert. Man konnte des Nachts von Neapel aus 2 schmale Lavaströme erkennen, die etwas divergirend an der NW-Seite des Kegels gegen das Atrio del cavallo herunterliefen. Sie entströmten einer Bocca, die etwa in gleicher Höhe mit der oberen Station der Drahtseilbahn und westlich von ihr gelegen war.

description: Most work on sense disambiguation presumes that one knows beforehand -- e.g. from a thesaurus -- a set of polysemous terms. But published lists invariably give only partial coverage. For example, the English word tan has several obvious senses, but one may overlook the abbreviation for tangent. In this paper, we present an algorithm for identifying interesting polysemous terms and measuring their degree of polysemy, given an unlabeled corpus. The algorithm involves: (i) collecting all terms within a k-term window of the target term; (ii) computing the inter-term distances of the contextual terms, and reducing the multi-dimensional distance space to two dimensions using standard methods; (iii) converting the two-dimensional representation into radial coordinates and using isotonic/antitonic regression to compute the degree to which the distribution deviates from a single-peak model. The amount of deviation is the proposed polysemy index

description: A model of an evolving network of interacting molecular species is shown to exhibit repeated rounds of crashes in which several species get rapidly depopulated, followed by recoveries. The network inevitably self-organizes into an autocatalytic structure, which consists of an irreducible `core' surrounded by a parasitic `periphery'. Crashes typically occur when the existing autocatalytic set becomes fragile and suffers a `core-shift', defined graph theoretically. The nature of the recovery after a crash, in particular the time of recovery, depends upon the organizational structure that survives the crash. The largest eigenvalue of the adjacency matrix of the graph is an important signal of network fragility or robustness.

description: The land use, land-use change and forestry (LULUCF) sector plays and will continue to play a crucial role in international efforts to mitigate climate change. Developing a greenhouse gas (GHG) inventory for the LULUCF sector is inherently associated with complexity and methodological difficulties. The ability to appropriately identify and classify land use and land-use changes is a key prerequisite for developing an inventory in line with the principles of the Intergovernmental Panel on Climate Change (IPCC). Recently, the Food and Agriculture Organization (FAO) released the Open Foris Collect Earth (CE) software to assist countries in collecting, managing and analyzing land-cover and land-use information. However, limited guidance is available to assist users in the design of the land categories and the collection of the necessary data for land representation in line with the IPCC principles. The different classification protocols that are currently followed, in parallel with the subjectivity in users’ interpretation, risk multiple users classifying the same land area under different land-use categories. This article proposes a methodological framework for using CE to prepare land area data that are complete, consistent, accurate, transparent and comparable, in accordance with the IPCC Guidelines.

description: Continuous mappings between compact Hausdorff spaces can be studied using homomorphisms between algebraic structures (lattices, Boolean algebras) associated with the spaces. This gives us more tools with which to tackle problems about these continuous mappings -- also tools from Model Theory. We illustrate by showing that the Čech-Stone remainder $[0,\infty)$ has a universality property akin to that of $N^*$; a theorem of Maćkowiak and Tymchatyn implies it own generalization to non-metric continua; and certain concrete compact spaces need not be continuous images of $N^*$.

description: Thousands of malicious applications targeting mobile devices, including the popular Android platform, are created every day. A large number of those applications are created by a small number of professional under-ground actors, however previous studies overlooked such information as a feature in detecting and classifying malware, and in attributing malware to creators. Guided by this insight, we propose a method to improve on the performance of Android malware detection by incorporating the creator's information as a feature and classify malicious applications into similar groups. We developed a system that implements this method in practice. Our system enables fast detection of malware by using creator information such as serial number of certificate. Additionally, it analyzes malicious be-haviors and permissions to increase detection accuracy. The system also can classify malware based on similarity scoring. Finally, we showed detection and classification performance with 98% and 90% accuracy respectively.

description: Knowledge discovery from data is an inherently iterative process. That is, what we know about the data greatly determines our expectations, and therefore, what results we would find interesting and/or surprising. Given new knowledge about the data, our expectations will change. Hence, in order to avoid redundant results, knowledge discovery algorithms ideally should follow such an iterative updating procedure. With this in mind, we introduce a well-founded approach for succinctly summarizing data with the most informative itemsets; using a probabilistic maximum entropy model, we iteratively find the itemset that provides us the most novel information--that is, for which the frequency in the data surprises us the most---and in turn we update our model accordingly. As we use the Maximum Entropy principle to obtain unbiased probabilistic models, and only include those itemsets that are most informative with regard to the current model, the summaries we construct are guaranteed to be both descriptive and non-redundant. The algorithm that we present, called MTV, can either discover the top-$k$ most informative itemsets, or we can employ either the Bayesian Information Criterion (BIC) or the Minimum Description Length (MDL) principle to automatically identify the set of itemsets that together summarize the data well. In other words, our method will `tell you what you need to know' about the data. Importantly, it is a one-phase algorithm: rather than picking itemsets from a user-provided candidate set, itemsets and their supports are mined on-the-fly. To further its applicability, we provide an efficient method to compute the maximum entropy distribution using Quick Inclusion-Exclusion. Experiments on our method, using synthetic, benchmark, and real data, show that the discovered summaries are succinct, and correctly identify the key patterns in the data.

description: Dwarf stars with debris discs and planets appear to be excellent laboratories to study the core accretion theory of planets formation. These systems are however, insufficiently studied. In this paper we present the main metallicity and lithium abundance properties of these stars together with stars with only debris discs and stars with only planets. Stars without detected planets nor discs are also considered. The analysed sample is formed by main-sequence FGK field single stars. Apart from the basic stellar parameters, we include the use of dusty discs masses. The main results show for the first time that the dust mass of debris disc stars with planets correlate with metallicity. We confirm that these disc dust masses are related to their central stellar masses. Separately, the masses of stars and those of planets also correlate with metallicity. We conclude that two conditions are necessary to form giant planets: to have a sufficient metallicity and also a sufficient protoplanetary mass of gas and dust. The debris discs masses of stars without giant planets do not correlate with metallicity, because they do not fulfil these two conditions. Concerning lithium, by adopting a stellar model for lithium depletion based on a strong interaction between the star and a protoplanetary disc, we found that in agreement with the model predictions, observations indicate that the main lithium depletion occurs during this initial protoplanetary evolution stage. We show that the ultimately lithium depletion is independent of the presence or absence of planets and appears to be only age dependent.

description: We study the properties of coreless vortices(skyrmion) in spinor Bose-Einstein condensate. We find that this excitation is always energetically unstable, it always decays to an uniform spin texture. We obtain the skyrmion energy as a function of its size and position, a key quantity in understanding the decay process. We also point out that the decay rate of a skyrmion with high winding number will be slower. The interaction between skyrmions and other excitation modes are also discussed.

description: GEODIA SIMPLEX SCHMIDT, 1870
 Geodia simplex, Schmidt, 1870: p. 70; Arndt, 1913: p. 112; Burton, 1930: p. 490; 1946: p. 856.
 Type locality and deposition of holotype: Egedesminde, West Greenland, 50–90 m, ZMUC-DEM-319 (wet specimen). Burton (1946) also speaks of a Schmidt spicule preparation from the type, still in the BMNH collection today (BMNH 70.5.3.79).
 Discussion: Arndt (1913) identified with hesitation a small specimen from Norway as G. simplex; the specimen has not been located. Burton (1946), after an examination of spicule preparations from the type material from Greenland, concluded that G. simplex is probably identical to G. cydonium, which explains why Burton (1959) later mentioned G. cydonium as occurring in Greenland and Norway. Also, Koltun (1966: 57) doubted the existence of G. simplex as an independent species. We have inspected the holotype, a whole specimen cut in two. It is a rounded lump, measuring c. 7 cm in diameter and 3 cm in height; the surface is damaged in some areas, and algae are growing on it. The cortex is 1 mm thick. The spicule repertoire is clearly that of G. cydonium from the Mediterranean Sea. However, there must be a mistake, most likely from Schmidt’s side, as the label is in his handwriting. The algae growing on the specimen do not occur in Greenland; on the contrary, one of the species is Mediterranean, another one Mediterranean–southern boreal (Dr Poul Møller Pedersen, pers. comm.). We therefore confirm that G. simplex is a junior synonym of G. cydonium. As molecular results suggest that G. cydonium is a species complex (Cárdenas et al., 2011), only a thorough morphological revision of this complex will tell us to which species group G. simplex belongs.

description: Discrete Lotka-Volterra equation over $p$-adic space was constructed since $p$-adic space is a prototype of spaces with the non-Archimedean valuations and the space given by taking ultra-discrete limit studied in soliton theory should be regarded as a space with the non-Archimedean valuations in the previous report (solv-int/9906011). In this article, using the natural projection from $p$-adic integer to a ring $Z/p^n Z$, a soliton equation is defined over the ring. Numerical computations shows that it behaves regularly.

description: The gas pixel detector (GPD) is designed and developed for high-sensitivity astronomical X-ray polarimetry, which is a new window about to open in a few years. Due to the small mass, low power, and compact geometry of the GPD, we propose a CubeSat mission Polarimeter Light (PolarLight) to demonstrate and test the technology directly in space. There is no optics but a collimator to constrain the field of view to 2.3 degrees. Filled with pure dimethyl ether (DME) at 0.8 atm and sealed by a beryllium window of 100 micron thick, with a sensitive area of about 1.4 mm by 1.4 mm, PolarLight allows us to observe the brightest X-ray sources on the sky, with a count rate of, e.g., ~0.2 counts/s from the Crab nebula. The PolarLight is 1U in size and mounted in a 6U CubeSat, which was launched into a low Earth Sun-synchronous orbit on October 29, 2018, and is currently under test. More launches with improved designs are planned in 2019. These tests will help increase the technology readiness for future missions such as the enhanced X-ray Timing and Polarimetry (eXTP), better understand the orbital background, and may help constrain the physics with observations of the brightest objects.

description: Regensburg, als Inbegriff einer mittelalterlichen "steinernen" Großstadt mit vielen kulturhistorisch bedeutsamen Bauwerken (z.B. Steinerne Brücke) weithin bekannt, weist darüber hinaus aber auch zahlreiche sehenswerte Grünanlagen auf. So gibt es in Regensburg allein 16 Parkanlagen mit rund 120 Hektar Gesamtfläche. Dies bedeutet eine Zunahme des Parkgrüns um das Vierfache seit der letzten Zustandsbeschreibung aus dem Jahre 1966 (Bd. 27, Ludwig Pongratz). Alle größeren Grünflächen zusammengenommen (Parkanlagen, Allee, Botanischer Garten, Naturschutzgebiet "Max-Schultze-Steig") nehmen immerhin eine Fläche von etwa 165 Hektar ein. 1985/86 wurde deshalb erstmals eine vollständige dendrologische Bestandsaufnahme dieser Flächen durchgeführt. Sie ergab 170 verschiedene - einheimische wie ausländische - Baumarten, zu denen noch etliche Variationen (unterschiedliche Wuchsformen, Blattformen und -färbungen) hinzukommen. Neben diesem Baumbestand in den Grünanlagen wurden zusätzlich noch 30 Naturdenkmäler registriert und beschrieben. Regensburg, known far and wide as a medieval city in stone with its many historically and culturally important buildings (e.g. "Steinerne Brücke"), is also impressive for its greenery, with no less than 16 parks covering 120 hectares. This surface represents a fourfold increase since the last survey in 1966 (vol. 27, Ludwig Pongratz). If extended to include the nature reserve "Max-Schultze-Steig", the botanical garden and the greenbelt, the total area devoted to some form of public garden rises to 165 hectares. It was for this reason, that in 1985/86 a coraprehensive stock-taking of the trees was carried out for the first time. This count pointed to 170 different species of trees, both native and alien, further more variations in growth pattern, leaf form and colour were observed and listed. In addition to the trees in the parks 30 natural monuments have also been registered.

description: The causes of major and rapid transitions observed in biological macroevolution as well as in the evolution of social systems are a subject of much debate. Here we identify the proximate causes of crashes and recoveries that arise dynamically in a model system in which populations of (molecular) species co-evolve with their network of chemical interactions. Crashes are events that involve the rapid extinction of many species and recoveries the assimilation of new ones. These are analyzed and classified in terms of the structural properties of the network. We find that in the absence of large external perturbation, `innovation' is a major cause of large extinctions and the prime cause of recoveries. Another major cause of crashes is the extinction of a `keystone species'. Different classes of causes produce crashes of different characteristic sizes.

Avifauna Ratisbonensis - Die Vogelwelt der Stadt Regensburg

description: Die Avifauna der Stadt Regensburg wird erstmals seit 1840 wieder im Zusammenhang dargestellt. Ihre Beschreibung stützt sich auf die Ergebnisse einer Rasterkartierung aus dem Jahre 1982 und von Siedlungsdichteuntersuchungen 1983 sowie die Notizen zahlreicher Beobachter unter besonderer Berücksichtigung der Jahre 1973 bis 1983. Insgesamt wurden innerhalb der Grenzen des heutigen Stadtgebietes 221 Vogelarten (seit 1840) festgestellt. An Brutvögeln wurden 1982 95 Arten/1983 99 Arten registriert, wovon 18 auf der ROTEN LISTE der gefährdeten Arten stehen. Die Siedlungsdichteuntersuchungen ergaben, daß das Stadtgebiet von Regensburg von vergleichsweise vielen Vogelarten, aber ungleichmäßig und relativ dünn besiedelt wird. Hinsichtlich der Qualität des Spektrums der Brutvogelarten erreicht das heutige Stadtgebiet nur einen durchschnittlichen Wert (maximal 285 Punkte nach dem Indexsystem von BEZZEL), doch kann es als "regional bedeutsamer" Lebensraum eingestuft werden. Angaben zur Phänologie, zurVerstädterung und zum Naturschutz ergänzen das Buch. The first full description of Regensburg's avifauna to have been published since 1840 is based on the results obtained from grid-mapping the City area in 1982, from censuses of the bird breeding in the City in 1982 as well as on the notes of numerous observes with particular reference to the years 1973 to 1983. Altogether 221 species have been recorded within Regensburg's boundaries since 1840. In 1983, 99 species bred in the City area (1982 - 95 species), 18 of which are on the list of endangered species. The censuses reveal that Regensburg is settled by a relatively large number of species, but unequally and rather scarcely. As regards the quality of the ränge of species breeding here, the present-day city area merits only an average Position (max. 285 points) on the BEZZEL index; nevertheless it may be classified as an area of regional importance. The book also contains information on phenology, Urbanisation and nature Conservation.

A growth gap for diffeomorphisms of the interval

description: Given an orientation-preserving diffeomorphism of the interval [0;1], consider the uniform norm of the differential of its n-th iteration. We get a function of n called the growth sequence. Its asymptotic behaviour is an interesting invariant which naturally appears both in geometry of the diffeomorphisms groups and in smooth dynamics. Our main result is the following Gap Theorem: the growth rate of this sequence is either exponential, or at most quadratic with n. Further, we construct diffeomorphisms with quite an irregular behaviour of the growth sequence. This construction easily extends to arbitrary manifolds.

Neben dem Lesen oder Zuhören spiegelt sich ja bei Jedem in der inneren Sicht des Gelesenen oder Gehörten das eigene Gedankenbild und die eigene Vorstellungskraft und damit eine von Mensch zu Mensch.,doch verschiedene Erfassung des Vergangenen. Ich habe versucht, aus alten mir erreichbaren Informationen ein Bild vergangener Zeiten aufzubauen, das aus meiner Sicht so aussieht, wie ich es darstelle, das aber aus der Sicht eines vielleicht besser informierten Lesers berichtigt werden könnte. Zwei Fragen haben mich gereizt und angespornt das Thema zu bearbeiten. Da war einmal eine Fülle von Hinweisen auf meine Vorfahren, die über mehrere Generationen hin den Beruf des Saliterers in Weiden ausübten. Sie werden also etwas mehr Vertrauliches aus der Genealogie der Manneslinie der Zrenner erfahren. Mit dieser vielleicht etwas trockenen Tatsachenfeststellung ist jedoch eine ganze Menge allzu Menschliches verbunden. Zum anderen weckte in mir die Neugier die Darstellung des Berufsbildes des ausgestorbenen Saliterhandwerks.

Ab Initio Evidence for the Formation of Impurity d(3z^2-r^2) Holes in Doped La_{2-x}Sr_xCuO_4

description: Using the spin unrestricted Becke-3-Lee-Yang-Parr density functional, we computed the electronic structure of explicitly doped La_{2-x}Sr_xCuO_4 (x = 0.125, 0.25, and 0.5). At each doping level, an impurity hole band is formed within the undoped insulating gap. This band is well-localized to CuO_6 octahedra adjacent to the Sr impurities. The nature of the impurity hole is A_{1g} in symmetry, formed primarily from the z^2 orbital on the Cu and p_z orbitals on the apical O's. There is a strong triplet coupling of this hole with the intrinsic B_{1g} Cu x^2-y^2/O1 p_{sigma} hole on the same site. Optimization of the c coordinate of the apical O's in the doped CuO_6 octahedron lead to an asymmetric anti-Jahn-Teller distortion of the O2 atoms toward the central Cu. In particular, the O2 atom between the Cu and Sr is displaced 0.26 A while the O2 atom between the Cu and La is displaced 0.10 A. Contrary to expectations, investigation of a 0.1 A enhanced Jahn-Teller distortion of this octahedron does not force formation of an x^2-y^2 hole, but instead leads to migration of the z^2 hole to the four other CuO_6 octahedra surrounding the Sr impurity. This latter observation offers a simple explanation for the bifurcation of the Sr-O2 distance revealed in x-ray absorption fine structure data.
