description: Die Beziehungen zwischen 31 Pflanzen und 7 chemischen Parametern des Wassers sowie der Basensättigung wurden in den Biberkessel-Mooren an der Hornisgrinde im Buntsandsteingebiet des Nördlichen Schwarzwaldes untersucht. Wöchentlich wurden in den Jahren 1977, 1978 und 1979 pH-Wert, Leitfähigkeit, Na, K, Ca, Mg und Fe des Wassers analysiert. Die Arten Sphagnum inundatum, Carex echinata, Deschampsia cespitosa, Scapania undulata zeichnen sich durch Maxima ihrer statistischen Verteilung im Bereich höherer Kationenkonzentrationen, höherer pH-Werte und geringerer Leitfähigkeit aus. Andromeda polyfolia ist eine Art, welche mit sehr geringen Kationenkonzentrationen auskommt. Sehr schwer sind Carex rostrata, C. canescens und Molinia caerulea einzuordnen. Dies liegt hauptsächlich an den geringen Kationenkonzentrationen sogar im Mineralbodenwasser des untersuchten Gebietes. Am besten eignet sich für die Beurteilung eines Standortes die Basensättigung.
description: The correlations between 31 plant species and 7 chemical parameters of the water and the base saturation were examined in the Biberkessel-Peatlands at the Hornisgrinde in the sandstone area of the Northern Black Forest. Conductivity, pH-value, Na, K, Ca, Mg and Fe in the water were measured weekly during the years 1977, 1978 and 1979. Species like Sphagnum inundatum, Carex echinata, Deschampsia cespitosa, Scapania undulata show maxima of their statistical distribution within the region of higher cation concentrations, higher pH-values and lower conductivity. Andromeda polyfolia is one of the species which can live at very low concentrations. It is rather difficult to classify species like Carex rostrata, C. canescens or Molinia caerulea. This is because of the low concentrations of cations even in the water of the mineral soil. Most suitable for the judgement of a habitat is the base saturation.

description: We consider theories containing gravity, at most one dilaton and form field strengths. We show that the existence of particular BPS solutions of intersecting extremal closed branes select the theories, which upon dimensional reduction to three dimensions possess a simple simply laced Lie group symmetry G. Furthermore these theories can be fully reconstructed from the dynamics of such branes and of their openings. Amongst such theories are the effective actions of the bosonic sector of M-theory and of the bosonic string. The BPS intersecting brane solutions form representations of a subgroup of the group of Weyl reflections and outer automorphisms of the triple Kac-Moody extension G+++ of the G algebra, which cannot be embedded in the overextended Kac-Moody subalgebra G++ characterising the cosmological Kasner solutions.

Charge Conjugation and Parity Violations as a Signature for Black Hole Formation or Other New Physics in Hadron Collisions

description: I point out that there have been essentially no tests of discrete symmetries, such as baryon number, charge conjugation (C), parity (P), strangeness, isospin, etc., in high energy, high pT hadron collisions. If, for example, black hole formation (BHF) occurs, we might expect large violations of C, P, >... I propose new tests of C and P that can be adapted to a variety of new physics scenarios by selecting events with appropriate topologies. Large effects, such as ~10% longitudinal polarizations of outgoing particles, might be expected in events involving BHF. These tests may provide more sensitive searches for new physics at existing colliders.

description: Access to sexual and reproductive health resources is a vital aspect of overall health and wellbeing. College students are in a unique position related to their sexual and reproductive health needs. It is imperative that colleges and universities both provide necessary sexual and reproductive health resources and also that they ensure students are able to readily access those resources. This qualitative research examined access to sexual and reproductive health resources at American University from the perspective of the undergraduate students through interviews. It identifies both facilitators and barriers to access, and makes recommendations for improvements to access. Findings encompass several barriers, including lack of knowledge and information, stigma and certain gender biases, cost and transportation barriers. There were also facilitators, including a number of very strong student-led groups, and a recent program focused on sexual violence prevention. Recommendations include a well-designed education and information program at orientation, increased visibility of programs and services offered on campus, and greater availability of free safer sex supplies and testing, among others.

description: Adult content constitutes a major source of Internet traffic. As with many other platforms, these sites are incentivized to engage users and maintain them on the site. This engagement (e.g., through recommendations) shapes the journeys taken through such sites. Using data from a large content delivery network, we explore session journeys within an adult website. We take two perspectives. We first inspect the corpus available on these platforms. Following this, we investigate the session access patterns. We make a number of observations that could be exploited for optimizing delivery, e.g., that users often skip within video streams.

Our calculation completes the first out of three steps (matching, mixing and matrix elements) that are necessary for finding the next-to-next-to-leading QCD corrections to this process. All such corrections must be calculated in view of the ongoing accurate measurements of the B -> Xs gamma branching ratio.

PC-Cluster simulator for joint infrastructure interdependencies studies
Creators: name: Singupuram, Siva Prasad Rao
Publisher: name: University of British Columbia
Year: 2011

description: Rapid advances in network interface cards have facilitated the interconnection of inexpensive desktop computers to form powerful computational clusters, wherein independent simulations can be run in parallel. In this thesis, a hardware and software infrastructure is developed for the simulation of a complex system of interdependent infrastructures. A PC-Cluster is constructed by interconnecting 16 off-the-shelf computers via high speed Scalable Coherent Interface (SCI) network adapter cards. To enable synchronized data transfer between the cluster nodes with very low latencies, a special library comprised of communication routines was developed based on low-level functions of the SCI protocols. Different interrupt mechanisms for synchronous data transfer between the cluster computers (nodes) were investigated. A new method of implementing the interrupts is developed to achieve a 3.6 μs latency for one directional data transfer, which is shown to be an improvement over the standard interrupt mechanisms. To facilitate distributed and concurrent simulation of Simulink models on different computers of the PC-Cluster, a special communication block with the appropriate GUI interface has been developed based on the Simulink S-Function and interfaced with the developed SCI library. A reduced-scale benchmark system comprised of some of the University of British Columbia's infrastructures including the Hospital, Substation, Power House, Water Station, and Steam Station has been chosen to investigate the operation of PC-Cluster and potential improvement in simulation speed compared to a single-computer simulation. The models of considered infrastructures are distributed to different computer nodes of the PC-Cluster and simulated in parallel to study their interdependencies in a case of emergency situations caused by an earthquake or a similar disturbing event. It is shown that an improvement of computational speed over a single computer can be achieved through parallelism using the SCI-based PC-Cluster. For the considered benchmark system, an increase in simulation speed of up to 5 times was achieved.
Möglichkeiten für die Wiedervernässung von Hochmooren in Abhängigkeit von der Torfmächtigkeit
Possibilities for rewetting of raised bogs in relation to the thickness of the peat layers
Creators: name: Schouwenaars, Jos
Publisher: name: FID GEO
Year: 1993

description: Zur Regeneration von Hochmooren durch Wiedervernässung werden geringe Wasserstandsschwankungen gefordert. Von großer Bedeutung ist die Schaffung einer hohen Wasserspeicherung nahe der Geländeoberfläche (z.B. mittels Überstauung im Winter), zudem sollen Sickerwasserverluste eingeschränkt werden. Für Staukörper aus stark zersetztem Schwarztorf (Humositätsgrad H ≥ 7) mit einer Wasserdurchlässigkeit von etwa 0,0001 m/Tag ist eine Mächtigkeit von 0,5 m oft ausreichend. Wenn aber Resttorfschichten mit einem Humositätsgrad von etwa H 5 bis 7 überwiegen, ist die Wasserdurchlässigkeit um den Faktor 2 bis 3 höher. Es wird festgestellt, daß es auch dann noch Möglichkeiten für eine erfolgreiche Wiedervernässung gibt. Mit einem "guten" Grundwasseranschluß, d.h. mit einer relativ hohen Druckhöhe des Grundwassers im Torfkörper, ist auch hier eine Staukörpermächtigkeit von 0,5 - 1 m oft ausreichend. Ohne einen Grundwasseranschluß wird für Resttorfschichten mit H < 7 eine Staukörpermächtigkeit von mindestens 1 m gefordert.
description: To create suitable hydrological conditions for the restoration of bogs by rewetting it is necessary to limit the fluctuations of the waterlevel. Of utmost importance is a high water storage capacity near the surface, e.g. by means of inundation in winter. Secondly, vertical downward water losses in the remaining peat layers have to be limited. For peat relicts (cutaways) with strongly humified peat (humification degree H ≥ 7) and very low hydraulic conductivity (about 0.0001 m/day) a thickness of about 0,5 m mostly is sufficient to guarantee limited water losses. However, when remaining peat layers are less humified (H 5-7) vertical hydraulic conductivity may be twice or three times as high. Here, in cutaways with shallow peat, sufficient rewetting can only be realized with the water pressure in the underlying aquifer reaching above the peat base. When these conditions cannot be realized, the remaining peat layers should have a minimal thickness of 1 m.

description: Die Niedersächsische Landesregierung hat in ihrer Koalitionsvereinbarung (SPD/Grüne) vom 12.06.1990 den Moorschutz besonders verankert. Ein weiterer Torfabbau soll nicht mehr möglich sein, bestehende Abbauvorhaben sollen überprüft werden. Im Umweltbericht der Niedersächsischen Landesregierung 1992 und im Entwurf des Landes-Raumordnungsprogramms vom Mai 1992 werden die Ziele für die Erhaltung der Moore genannt. Die Anforderungen an einen weiteren Torfabbau werden dargestellt. Es wird beschrieben, wie der bestehende Torfabbau zu Ende geführt werden kann und welche Möglichkeiten noch für einen künftigen Torfabbau bestehen. Die Anforderungen an die Erarbeitung von Abbauanträgen werden aufgezählt und erläutert. Im Rahmen der Abbauanträge müssen die planerischen Grundlagen für die spätere Entwicklung der abgebauten Flächen erarbeitet werden. Die Entwicklung der abgetorften Flächen ist von der Vornutzung, den verbleibenden Resttorfen und der Abbaumethode abhängig. Deshalb werden Hinweise zu den unterschiedlichen Abbauverfahren und der Behandlung der abgetorften Flächen gegeben. Abschließend wird auf die Aktualisierung des Niedersächsischen Moorschutzprogramms und die im Rahmen dieser Arbeit laufenden Auswertungen und die vorgesehene Darstellung hingewiesen.
description: The government of the state of Lower Saxony in its coalition agreement between the Social Democratic and the Green Party of June 12th, 1990‚put special attendance to peat-bog conservation. Further excavation should not be permitted, existing concessions be examined. In the Environmental Report of Lower Saxony, 1992, and in the draft of the State Land-Use Plan of May, 1992, these claims for peatland conservation can be found as well. Description of the demands for peat excavation in the future is given, in the same time it is indicated how the existing excavation should be brought to an end and which possibilities for further peat winning exist. The requests necessary for future excavation plans are listed up and explained. With these plans the base for the after-use of the winning areas is laid. Development of excavated areas is dependent on the pre-use, the remaining peat and the excavation method. Proposals are made with respect to the influence of different excavation measures and treatment of excavation areas. Finally a description is given on the actualization of the Lower Saxonian Peatland Conservation Act and on studies and research within this program.

description: Analyzing the $\ell +n$-$jets+ \met$ (where $n \ge 2 $), data from Run-I of the Tevatron using the Bayesian technique, we obtain model independent limits on the product $\br(\lstop\ra be^{+}ν_e \lspone) \times \br(\lstop^{*}\ra \bar{b}q\bar{q^{\prime}}\lspone)$ for different values of the lighter top squark($\lstop$) mass and the lightest supersymmetric particle($\lspone$) mass. The SUSY signals have been simulated by interfacing the 4-body decay of $\lstop$ at the parton level with the event generator PYTHIA. These limits have been translated into exclusion plots in the $\mlstop$-$\mlspone$ plane, which also turn out to be fairly model independent for fixed values of the BR of the competing loop decay mode $\lstop\ra c \lspone$. Assuming the loop decay BR to be negligible and using the leading order cross section for $\lstoplstop$ pair production, we obtain conservatively $\mlstop \ge $77.0 (74.5) GeV for $\mlspone$=5(15) GeV, while for $\br(\lstop\ra c \lspone)$=20%, the corresponding limits are $\mlstop \ge $68.0 (65.0) GeV. Using the larger next to leading order cross-section stronger limits are obtained. For example, if $\br(\lstop\ra c \lspone)$=20%, $\mlstop \ge $73.0 (72.7) GeV for $\mlspone$=5(15) GeV. Our limits nicely complement the ALEPH bounds which get weaker for low $\mlspone$.

description: A new generalization of the Gray map is introduced. The new generalization $Φ: Z_{2^k}^n \to Z_{2}^{2^{k-1}n}$ is connected with the known generalized Gray map $ϕ$ in the following way: if we take two dual linear $Z_{2^k}$-codes and construct binary codes from them using the generalizations $ϕ$ and $Φ$ of the Gray map, then the weight enumerators of the binary codes obtained will satisfy the MacWilliams identity. The classes of $Z_{2^k}$-linear Hadamard codes and co-$Z_{2^k}$-linear extended 1-perfect codes are described, where co-$Z_{2^k}$-linearity means that the code can be obtained from a linear $Z_{2^k}$-code with the help of the new generalized Gray map.

description: We study three-body decays of $Λ_c^{*}(2765) \to Λ_c^+π^+π^-$ by using effective Lagrangians in a non-relativistic framework. We consider the sequential decays through $Σ_c(2455)π$ and $Σ_c^*(2520)π$ in intermediate states which are dominant contributions. The coupling constants in the effective Lagrangians are computed in the quark model. We demonstrate that the ratio $R= Γ(Λ_c^*\toΣ_c^*(2520)π)/Γ(Λ_c^*\to Σ_c(2455)π)$ and angular correlations are sensitive to the spin and parity of $Λ_c^{*}(2765)$. Thus, the measurement of these observables in experimental facilities such as Belle and LHCb can provide useful constraints to determine the spin and parity of $Λ_c^{*}(2765)$.

description: The expansion of Kummer's hypergeometric function as a series of incomplete Gamma functions is discussed, for real values of the parameters and of the variable. The error performed approximating the Kummer function with a finite sum of Gammas is evaluated analytically. Bounds for it are derived, both pointwisely and uniformly in the variable; these characterize the convergence rate of the series, both pointwisely and in appropriate sup norms. The same analysis shows that finite sums of very few Gammas are sufficiently close to the Kummer function. The combination of these results with the known approximation methods for the incomplete Gammas allows to construct upper and lower approximants for the Kummer function using only exponentials, real powers and rational functions. Illustrative examples are provided.

This has been proposed for studying the Quantum Hall Effect as well as High-Temperature Superconductivity. The gauge field can be coupled to a scalar field either relativistically or non-relativistically. In both cases, one admits finite-energy, vortex solutions.

Photometric and dynamic evolution of an isolated disc galaxy simulation

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

description: We present a detailed analysis of the evolution of a simulated isolated disc galaxy. The simulation includes stars, gas, star formation and simple chemical yields. Stellar particles are split in two populations: the old one is present at the beginning of the simulation and is calibrated according to various ages and metallicities; the new population borns in the course of the simulation and inherits the metallicity of the gas particles. The results have been calibrated in four wavebands with the spectro-photometric evolutionary model GISSEL2000 (Bruzual & Charlot 1993). Dust extinction has also been taken into account. A rest-frame morphological and bidimensional photometric analysis has been performed on simulated images, with the same tools as for observations. The effects of the stellar bar formation and the linked star formation episode on the global properties of the galaxy (mass and luminosity distribution, colours, isophotal radii) have been analysed. In particular, we have disentangled the effects of stellar evolution from dynamic evolution to explain the cause of the isophotal radii variations. We show that the dynamic properties (e.g. mass) of the area enclosed by any isophotal radius depends on the waveband and on the level of star formation activity. It is also shown that the bar isophotes remain thinner than mass isodensities a long time (> 0.7 Gyr) after the maximum of star formation rate. We show that bar ellipticity is very wavelength dependent as suggested by real observations. Effects of dust extinction on photometric and morphological measurements are systematically quantified.

description: We introduce a variational wave-function to study the polaron formation when the electronic transfer integral depends on the relative displacement between nearest-neighbor sites giving rise to a non-local electron-phonon coupling with optical phonon modes. We analyze the ground state properties such as the energy, the electron-lattice correlation function, the phonon number and the spectral weight. Variational results are found in good agreement with analytic weak-coupling perturbative calculations and exact numerical diagonalization of small clusters. We determine the polaronic phase diagram and we find that the tendency towards strong localization is hindered from the pathological sign change of the effective next-nearest-neighbor hopping.

description: We examine the relationship between productivity characteristics and the process of restructuring and ownership changes in the supermarket industry. Contrary to studies in the manufacturing sector, ownership changes alone do not improve productivity. Rather, a change from wholesaler-distribution to self-distribution does significantly improve productivity. Logically, management would be motivated to acquire both the stores and the distribution centers owned by large firms in order to increase productivity as part of a strategy to improve competitiveness and market access.

description: What are the factors that motivate youth to take up arms and mobilize in organized violence? That is the central question of this project, applied to two case contexts, Sri Lanka and Nicaragua. The project's integrative system dynamics methodology synthesizes competing causal explanations that are often considered in isolation within the literature. Three mechanisms are hypothesized to influence the "attractiveness" of armed mobilization for at-risk youth sectors: 1) Groups and Identity; 2) Grievances and (Perceived) Injustice; and 3) Greed and Incentives, with expected shifts across time and institutional context. Causal loop diagrams communicate the model's conceptual framework, key variable relationships, and interactive feedback effects across mechanisms. For purposes of testing, the model is contextualized to initial values for both cases, simulated across time (1960-2010), and then examined against the available empirical data for Sri Lanka and Nicaragua. Case illustrative narratives link quantitative and qualitative analysis of violent mobilization (and demobilization) for targeted historical periods. In Sri Lanka, analysis highlights the relative "attractiveness" for Sinhalese young people joining armed insurrections of the JVP (the "People's Liberation Front", a radical Maoist group with Buddhist roots), or for young Tamils joining ethno-nationalist armed groups such as the Liberation Tigers of Tamil Eelam. In Nicaragua, model analysis traces the "attractiveness" of youth joining Marxist-nationalist Sandinista revolutionaries in the 1970s, with counter-revolutionary Contra forces in the 1980s, and fragmented neighborhood gangs from 1990. Project results show strong correspondence between the applied model simulations and the case historical record, for estimating the number of youth militants and their period-specific causal factor explanations. Model "leverage points" are highlighted across both cases, and then applied to a shadow case study (Israel-Palestine) as a proof-of-concept model extension (without simulation). From there, the text offers critical discussion of model limitations and potential extensions, and delineates key implications for policymaking, programming, and peacebuilding applications. The project concludes by highlighting the necessity of considering multiple causal explanations for a comprehensive understanding of armed youth mobilization. Moreover, it provides a systematic and rigorous framework to test these explanations' relative strength and their variance across time.

description: A factorization of spacetime of the form M^3xM^3xM^3 is considered in this paper as the closed string background in type IIA. The idea behind this construction is that each M^3 might give rise to one large spatial dimension of 4-dimensional spacetime in the closed string sector. In the open string sector, intersecting D6-branes can be constructed for the simple choice of an orientifolded M^3=T^3 in a similar way as on the prominent T^6=T^2xT^2xT^2 using exact CFT. The D6-branes then are allowed to span general 2-cycles on each T^3. The intersection 1-cycles between two stacks of branes on one T^3 can be understood as one spatial dimension of the effective 4-dimensional 'spacetime' for the massless chiral fermions charged under these two stacks. Additionally to the known solutions to the R-R tadpole equations conserving (3+1)-dimensional Poincare invariance, this allows for solutions with globally just (2+1)- or (1+1)-Poincare invariance. For non-supersymmetric solutions, a string tree-level and one-loop potential for the scalar moduli (including the spacetime radii) is generated in the NS-NS sector. This potential here is interpreted dynamically for radii and dilaton in order to describe the global evolution of the universe. In the late time picture, (3+1)-dimensional global Poincare invariance can be restored well within experimental bounds. This approach links particle properties (the massless chiral fermion spectrum) directly to the global evolution of the universe by the scalar potential, both depending on the same topological wrapping numbers. In the future, this might lead to much better falsifiable phenomenological models.

description: Abstract: The range extension, phytosociology and ecology of Sphagnum riparium for the Arnsberger Wald, the largest forest area in North Rhine-Westphalia (Germany) are discussed in detail. The occurrence of Sphagnum riparium in the Arnsberger Wald seems to be the furthermost northwest exposed subarea in central Europe of this species. Major aspects are the distinct floristic structure primarely referring to communities of open fens and the specific habitat preferences illustrating a remarkable hydrological and micro-climatically stability. The analysis of the hydrochemical properties indicates poor nutrition conditions, but moderate base availabilities at the sites examined. In addition the endangerment of the Sphagnum riparium-rich habitats in the Arnsberger Wald is described.
description: Zusammenfassung: Sphagnum riparium besitzt im Arnsberger Wald einen regionalen Verbreitungsschwerpunkt, wobei es sich um das am weitesten nach Nordwesten exponierte Teilareal dieser Art in Mitteleuropa handelt. Das Torfmoos kommt v. a. in lichten, quellnahen Sumpf- und Moorwäldern in den höheren Lagen dieses Waldgebietes vor und hat hier unter Optimalbedingungen relativ ausgedehnte und vitale Be stände aufgebaut. Die hydrochemischen Messwerte belegen, dass sich die Standorte der überprüften Sphagnum riparium-reichen Phytozönosen im Arnsberger Wald durch eingeschränkte Nährstoffverfügbarkeiten, aber auch durch günstigere Basengehalte auszeichnen. Sie sind pflanzensoziologisch überwiegend den Niedermoor-Gesellschaften des Caricion nigrae anzuschließen und lassen sich in fünf floristisch und z. T. auch ökohydrologisch gut charakterisierbare Vegetationseinheiten gruppieren.

The Evolutionaries: Transforming the Political System and Culture in Lebanon

description: The Evolutionaries poses the question: How can grassroots activists broaden the space for political participation in a factionalized and elite-centric, as opposed to citizen-centric, polity? This question is explored through a case study of a new `civic' segment of civil society in Lebanon, which after the end of the 1975-1990 civil war managed to carve a space in which to operate and established itself as a factor in Lebanese politics. This `civic movement' employs an incremental change approach in order to transform their patron-dominated `republic' into a republic, which recognizes the rights and responsibilities associated with citizenship. To this end, civic activists link with political elites in time- and scope-limited campaigns. The temporary character of these coalitions reduces the risk of cooptation, and the limited scope reduces the number of stakeholders threatened by the campaign. However, while the Lebanese state demonstrates relatively low levels of constraints to civic activists, constraints emanating from society are at times severe. The historical development of the Lebanese state, especially the construction of a confessional political system, has reinforced a political culture centered on kinship and sectarian collective identities. Consequently, in times of high tension and political polarization, the civic movement struggles to construct movement frames that resonate among the broader populace. Opportunities and constraints are traditionally sought on the level of the state, while culture and collective identities are examined as strategic tools, or invoked to explain the outcome of a movement after it has formed. However, a long-term perspective that captures the low-intensity dynamics that precede and succeed high-intensity popular mobilizations suggests that the social environment should also be understood as permissive or restrictive to movement formation. For instance, a `social opportunity' can arise when the hegemonic political culture becomes contested in broad layers of the populace, as was the case when broad popular discontent with the traditional leadership during the civil war provided Lebanon's civic movement with a constituency. Thus, the findings of this study suggest that shifts in the way individuals understand and interpret their environment can provide opportunities for Lebanon's `Evolutionaries' to initiate a slow process of political and societal transformation.
