title: Prozessorientierte Untersuchung zum Nitratabbauvermögen der Grundwasserkörper im Hessischen Ried
Creators: name: Kludt, Christoph
Publisher: name: UNSPECIFIED
Year: 2021

description: Mikrobiologische Abbauprozesse tragen maßgeblich zur Minderung der Nitratbelastung in sedimentären Grundwasserleitern bei, indem Nitrat unter Verbrauch von organischem Kohlenstoff (heterotroph) und Eisensulfiden bspw. Pyrit (autotroph) reduziert wird. Allerdings sind diese Phasen in Sedimenten oft nur in Spuren vorhanden und werden im Verlauf der Reaktionen aufgebraucht, sodass der Nitratabbau zum Erliegen kommen könnte. Um Maßnahmen im Zuge der EG-Wasserrahmenrichtlinie umsetzen zu können, wurden das Nitratabbaupotential und die Abbauprozesse in den z. T. stark nitratbelasteten Grundwasserleitern des Hessischen Rieds untersucht. Das Abbaupotential wurde an Bohrkernproben mittels Festphasenanalytik quantifiziert und charakterisiert. Mit Nitratabbauversuchen im Labor (Batch- und Säulenversuchen) wurden Erkenntnisse über die Verfügbarkeit des in den Sedimenten vorhandenen Abbaupotentials gewonnen, wobei die in dem Säulenversuch beobachteten Prozesses in einem reaktiven Transportmodell abgebildet wurden. Mit tiefenorientierter Untersuchung der Hydrochemie (u. a. stabile Isotope und N2Exzess) konnten Nitrateinträge, Abbaufortschritt und Abbauprozesse sowie durchschnittliche Abbauraten im Anstrom ausgewählter Grundwassermessstellen bestimmt werden. Trotz vergleichsweise geringer Sulfidgehalte, konnte sowohl in den Nitratabbauversuchen als auch direkt im Grundwasser oft ein dominant autotropher Nitratabbau nachgewiesen werden. Die Ergebnisse dieser Studie sollen einen Beitrag zur Identifizierung von Risikogebieten liefern, in deren Abstrom in naher Zukunft, bei gleichbleibend hohen Nitrateinträgen, mit nachlassendem Nitratabbau gerechnet werden muss.

description: In this paper we construct a higher order expansion of the manifold of quasi unidirectional waves in the Fermi-Pasta-Ulam (FPU) chain. We also approximate the dynamics on this manifold. As perturbation parameter we use $h^2=1/n^2$, where $n$ is the number of particles of the chain. It is well known that the dynamics of quasi unidirectional waves is described to first order by the Korteweg-de Vries (KdV) equation. Here we show that the dynamics to second order is governed by a combination of the first two nontrivial equations in the KdV hierarchy -- for any choice of parameters in the FPU potential. On the other hand, we find that only if the parameters of the FPU potential satisfy a condition, then a combination of the first three nontrivial equations in the KdV hierarchy determines the dynamics of quasi unidirectional waves to third order. The required condition is satisfied by the Toda chain. Our results suggest why the close-to-integrable behavior of the FPU chain (the FPU paradox) persists on a time scale longer than explained by the KdV approximation, and also how a breakdown of integrability (detachment from the KdV hierarchy) may responsible for the eventual thermalization of the system.

description: Predicting the popularity of social media content in real time requires approaches that efficiently operate at global scale. Popularity prediction is important for many applications, including detection of harmful viral content to enable timely content moderation. The prediction task is difficult because views result from interactions between user interests, content features, resharing, feed ranking, and network structure. We consider the problem of accurately predicting popularity both at any given prediction time since a content item's creation and for arbitrary time horizons into the future. In order to achieve high accuracy for different prediction time horizons, it is essential for models to use static features (of content and user) as well as observed popularity growth up to prediction time. We propose a feature-based approach based on a self-excited Hawkes point process model, which involves prediction of the content's popularity at one or more reference horizons in tandem with a point predictor of an effective growth parameter that reflects the timescale of popularity growth. This results in a highly scalable method for popularity prediction over arbitrary prediction time horizons that also achieves a high degree of accuracy, compared to several leading baselines, on a dataset of public page content on Facebook over a two-month period, covering billions of content views and hundreds of thousands of distinct content items. The model has shown competitive prediction accuracy against a strong baseline that consists of separately trained models for specific prediction time horizons.

description: Matrix theory and its applications make wide use of the eigenprojections of square matrices. The present paper demonstrates that the eigenprojection of a matrix $A$ can be calculated with the use of any annihilating polynomial of A^u, where u >= ind A. This enables one to find the components and the minimal polynomial of A, as well as the Drazin inverse A^D.

Possible connection between the reflection symmetry and existence of equatorial circular orbit

description: We study a viable connection between the circular-equatorial orbits and reflection symmetry across the equatorial plane of a vacuum stationary axis-symmetric spacetime in general relativity. The behavior of the circular equatorial orbits in the direction perpendicular to the equatorial plane is studied, and different outcomes in the presence and in the absence of the reflection symmetry are discussed. We conclude that in the absence of the equatorial reflection symmetry neither stable nor unstable circular orbit can exist on the equatorial plane. Moreover, to address the observational aspects, we provide two possible examples relating gravitational wave astronomy and the thin accretion disk which can put constraints on the symmetry breaking parameters.

Failure behaviour of two landslides in silt and clay
Creators: name: Fletcher, Lara Alexandria
Publisher: name: University of British Columbia
Year: 2009

description: Two large landslides in overconsolidated glacio-lacustrine clay and silt deposits of British Columbia river valleys have been examined: the Attachie landslide, Peace River and the Slesse Park landslide, Chilliwack River. Both cases are quite similar in their main aspects. However, their failure behaviour was markedly different. One exhibited intermittent ductile deformations typical of compound landslides in stiff clay. The other developed suddenly into a catastrophic, extremely rapid flow-slide of 6.4 Mm³ , following tens of years of slow, probably episodic movement. A comparison of the two cases is presented, with the purpose of explaining the difference in their failure behaviour. Comparison includes physiography, ground water characteristics, stratigraphy, material properties of the dominant units, and geometry. The most significant difference between the two cases, apart from scale (volume) is the presence at Attachie of a considerable content of non-plastic, cemented, unsaturated silt units. Three possible mechanisms for brittle flow slide formation are proposed. The first, undrained brittleness, is the usual cause of flow slides in what are generally described as cohesionless, weakly bound or cemented, high porosity materials (Hutchinson, 1992). At small strains the soil structure collapses resulting in a sudden reduction in shear strength and allowing a flow slide to develop. The second is a process that leads to what can be described as "macroscopic" brittleness. In short, a substantial portion of the previously intact soil volume is transformed into a mass of blocks of intact clay and till separated by joints filled with a disturbed, loosely deposited matrix. Liquefaction of the loose material then occurs, exerting heavy fluid pressure inside the cracks. The third was proposed by Hutchinson (1987) to explain the 1963 Vaiont Slide in Italy. The factors which lead to this behaviour include: 1) a compound (markedly noncircular) shape of the bounding slip surface, so that the slide forms initially a kinematically inadmissible mechanism; 2) a strong contrast between a low shear strength, non-brittle bounding slip surface and a high strength, brittle slide mass. These conditions may produce a stored deficit in the overall factor of safety on the boundary shear surfaces, which can be suddenly released by a brittle failure along internal shears in the slide mass. Results of stability analyses suggest that a combination of the latter two mechanisms likely led to the development of the flow slide.

description: A reliable census of pre-main sequence stars with known ages is critical to our understanding of early stellar evolution, but historically there has been difficulty in separating such stars from the field. We present a trained neural network model, Sagitta, that relies on Gaia DR2 and 2MASS photometry to identify pre-main sequence stars and to derive their age estimates. Our model successfully recovers populations and stellar properties associated with known star forming regions up to five kpc. Furthermore, it allows for a detailed look at the star-forming history of the solar neighborhood, particularly at age ranges to which we were not previously sensitive. In particular, we observe several bubbles in the distribution of stars, the most notable of which is a ring of stars associated with the Local Bubble, which may have common origins with the Gould's Belt.

description: Evidence from recent U.S. food consumption surveys provides new information on the distribution of rice consumption, the characteristics of rice consumers, and the diets of people who consume rice. Recently available data from nationally representative surveys of food consumed by individuals in the United States allowed comparison of consumption today (2001-02) with consumption in the mid-1990s. Data come from the Continuing Survey of Food Intakes by Individuals (1994-96) and the National Health and Nutrition Examination Survey (2001-02). Rice is consumed by a significant portion of the U.S. adult population. In 2001-02, over 18 percent (18.2 percent) of adults reported eating at least half a serving of white or brown rice in one day of observed intake. This share was slightly higher than that of 1994-96 (17.4 percent). Compared with others, individuals who consumed at least half a serving of white or brown rice in the observed day of intake consumed a smaller share of calories per day from fat and saturated fat; less discretionary fat or added sugar; and more fiber, dietary folate, fruit, vegetables, and enriched grains. Consumers eating rice were more likely to eat a diet that included choices of foods consistent with the 2005 U.S. Dietary Guidelines.

description: The tension among measurements of $V_{us}$ from different channels, the so-called Cabibbo Angle Anomaly, can be interpreted as a signal of lepton flavor universality (LFU) violation in the $W$ boson couplings. We investigate this issue in the framework of effective field theory, keeping the gauge structure of the Standard Model (SM) unchanged. We introduce gauge-invariant dimension-6 effective operators that couple the Higgs doublet to leptons, thereby giving non-universal tree-level contributions to the couplings of electroweak gauge bosons. Due to the $SU(2)_L$ gauge symmetry, a tension arises between the $V_{us}$ measurements that are affected by new $W$ couplings, and the electroweak precision measurements, which are also affected by the new $Z$ couplings. We show that this tension can be alleviated by allowing additional sources of gauge-invariant couplings of $Z$ boson to left- or right-handed leptons, and find the optimal regions indicated by the current data in the Wilson-coefficient space. We illustrate our model-independent results with the examples of minimal extensions of the SM involving the vector-like lepton (VLL) models. We point out that dimension-6 operators coupling the Higgs doublet to leptons can affect the rate of $h \to ττ$ decay significantly in general, however this effect is restricted to less than a per cent level for the minimal VLL models.

description: Aims: To predict time delays for a sample of gravitationally lensed quasars and to evaluate the accuracy that can be realistically achieved on the value of H_0. Methods: We consider 14 lensed quasars that are candidates for time-delay monitoring and model them in detail using pixelized lens models. For each system, we provide a mass map, arrival-time surface and the distribution of predicted time-delays in a concordance cosmology, assuming H_0^{-1}=14 Gyr (H_0=70 in local units). Based on the predicted time-delays and on the observational circumstances, we rate each lens as `excellent' or `good' or `unpromising' for time-delay monitoring. Finally, we analyze simulated time delays for the 11 lens rated excellent or good, and show that H_0 can be recovered to a precision of 5%. Results: In combination with COSMOGRAIL paper I on the temporal sampling of lensed quasar light curves, the present work will help design monitoring campaigns of lensed quasars.

description: A subtree of a tree is any induced subgraph that is again a tree (i.e., connected). The mean subtree order of a tree is the average number of vertices of its subtrees. This invariant was first analyzed in the 1980s by Jamison. An intriguing open question raised by Jamison asks whether the maximum of the mean subtree order, given the order of the tree, is always attained by some caterpillar. While we do not completely resolve this conjecture, we find some evidence in its favor by proving different features of trees that attain the maximum. For example, we show that the diameter of a tree of order $n$ with maximum mean subtree order must be very close to $n$. Moreover, we show that the maximum mean subtree order is equal to $n - 2\log_2 n + O(1)$. For the local mean subtree order, which is the average order of all subtrees containing a fixed vertex, we can be even more precise: we show that its maximum is always attained by a broom and that it is equal to $n - \log_2 n + O(1)$.

Both models display power-law distributions for various quantities of evolutionary interest, such as the lifetimes of individual species, the quiet periods between evolutionary upheavals larger than a given cutoff, and the sizes of extinction events. Time series of the diversity and measures of the size of extinctions give rise to flicker noise. Surprisingly, the power-law behaviors of the probability densities of quiet periods in the two models differ, while the distributions of the lifetimes of individual species are the same.

description: In recent years, it has become apparent that ratios of usual intakes of dietary components, such as the percent of calories from fat or the percent of calories from standard fat, are important indicators of dietary adequacy. The problem of estimating a percentile of the distribution of ratios of usual intakes of nutrients presents problems that arise from the fact that, from a statistical point of view, ratios of dietary components can be viewed as ratios of random variables. The methods developed by Nusser et al. (1995) to estimate usual intake distributions of nutrient, for example, cannot be directly applied to ratios, since the ratio of usual intakes is not equal to the mean of the ratio of daily intakes. In this paper we discuss the problem of estimating the intake distribution of ratios of dietary components by using an extension of the method developed by Beale (1962). The method we propose consists of first estimating the daily ratio of dietary components for each individual to obtain a nearly unbiased ratios estimate, and then applying the method developed at Iowa State University to estimate the distribution of usual intakes of the ratio. We use data collected in the 1989-91 CSFII, and consider six ratios to illustrate the procedure.

description: We investigate the transfer of energy from large scales to small scales in fully developed forced three-dimensional MHD-turbulence by analyzing the results of direct numerical simulations in the absence of an externally imposed uniform magnetic field. Our results show that the transfer of kinetic energy from the large scales to kinetic energy at smaller scales, and the transfer of magnetic energy from the large scales to magnetic energy at smaller scales, are local, as is also found in the case of neutral fluids, and in a way that is compatible with Kolmogorov (1941) theory of turbulence. However, the transfer of energy from the velocity field to the magnetic field is a highly non-local process in Fourier space. Energy from the velocity field at large scales can be transfered directly into small scale magnetic fields without the participation of intermediate scales. Some implications of our results to MHD turbulence modeling are also discussed.

title: Experimente zum Strömungs- und Benetzungsverhalten von Fluiden im Hochscherratenbereich am Beispiel des Rakelprozesses
Creators: name: Bitsch, Thorsten

description: Der Rakelprozess ist einer der wichtigsten Teilprozesse des Tiefdrucks. Den Tiefdruck zeichnet seine vergleichsweise hohen Druckgeschwindigkeiten und Reproduzierbarkeit aus. Die Rakel streift das Fluid von der Druckform, befüllt die Gravur der Druckform und befreit die nicht- druckenden Stellen des Druckformzylinders von Druckfluid. Dazu wird eine Rakel unter einem Rakelwinkel θ an den Druckformzylinder angepresst. Die Rakelgeometrie und die Beschichtung der Rakel können variieren. Weiter haben Druckformzylinder unterschiedliche Gravurparameter, die möglicherweise den Rakelprozess und die Strömung an der Rakel beeinflussen. Im Rakelprozess treten Störungen auf, die von Einflussgrößen wie Rakelanpresskraft, Rakelgeschwindigkeit, der Kapillarzahl des Prozesses und des verwendeten Fluids abhängen. Dabei hat die Scherung des Fluids bei newtonschen und nicht-newtonschen Fluiden jeweils unterschiedliche Auswirkungen auf den Rakelprozess, da sich die Viskosität der jeweiligen Fluide unterschiedlich verändert. Die Rakelanpresskraft führt dazu, dass sich ein effektiver Rakelwinkel θeff einstellt, der kleiner als der eingestellte Rakelwinkel ist. Auf Grund mechanischer Abrasion entstehen Abriebpartikel, die in den Rakelprozess eingebracht werden und möglicherweise den Rakelprozess und das Druckergebnis beeinflussen. In der vorliegenden Arbeit wird die Konzeptionierung eines Rakelmessstands behandelt, der unterschiedliche Experimentanordnungen sowie die Beobachtung des Rakelprozesses mit einer Hochgeschwindigkeitskamera ermöglicht. Ein transparenter Hohlzylinder und ein optisches Prisma ermöglichen die Beobachtung der Rakel aus dem Inneren des Zylinders. Eine μPTV-Methode wird damit möglich, um das Strömungsfeld an der Rakel aufzuklären.

description: We compute exactly the average spatial density for $N$ spinless noninteracting fermions in a $2d$ harmonic trap rotating with a constant frequency $Ω$ in the presence of an additional repulsive central potential $γ/r^2$. We find that, in the large $N$ limit, the bulk density has a rich and nontrivial profile -- with a hole at the center of the trap and surrounded by a multi-layered "wedding cake" structure. The number of layers depends on $N$ and on the two parameters $Ω$ and $γ$ leading to a rich phase diagram. Zooming in on the edge of the $k^{\rm th}$ layer, we find that the edge density profile exhibits $k$ kinks located at the zeroes of the $k^{\rm th}$ Hermite polynomial. Interestingly, in the large $k$ limit, we show that the edge density profile approaches a limiting form, which resembles the shape of a propagating front, found in the unitary evolution of certain quantum spin chains. We also study how a newly formed droplet grows in size on top of the last layer as one changes the parameters.

Attachment the construct : a construct validity study of parent-adolescent attachment measures
Creators: name: Bablitz, Stacey A.
Publisher: name: University of British Columbia
Year: 2009

description: A dearth of research evaluating the psychometric properties of parentchild attachment measures has raised questions about the validity of scores when these self-report instruments are administered. The purpose of this study was to examine the construct validity of the scores produced by two parentadolescent attachment measures on a sample of 200 adolescents grades eight through twelve who volunteered to take part in the project. The scores obtained from the 200 adolescents on the parent-child attachment questionnaires were analyzed using confirmatory factor analysis of the measurement models delineated by the authors of the scales. Structural equations modeling in LISREL was used to address the invariance of the factor structures for each attachment scale across the sex groupings. When comparing the correlation coefficients within and between the score from the IPPA, PAQ, RCMAS, and SDQ-II, the study generally supported the convergent and discriminant validity of the two attachment measures. However, results from the current sample failed to provide support for the factor structure of the IPPA and the PAQ, and the invariance of the measurement models across female and male participants. Taken together, results from the current study suggest that school psychologists or counsellors can use the total scores of the parent forms of the IPPA and PAQ in group or individual assessment as initial indicators of parent-child attachment and felt security. However, as with all assessments, the results should be interpreted in the context of information gained from other methods including interviews, observations, and self-reports measuring other constructs.

description: Dicho trabajo analiza que pese a que las medidas de aislamiento social por la pandemia por COVID-19, han generado una mejora en la calidad ambiental, dicho beneficio no sería sostenible en el tiempo, toda vez que es consecuencia de una situación extraordinaria. Por el contrario, identifica la posibilidad de que se produzca la flexibilización y aplazamiento de las normas y políticas ambientales, como medidas para impulsar la economía. Ante ello, se postula que tanto los problemas causados por el COVID-19, así como los ambientales, económicos y sociales, sean analizados bajo la tesis del macroscopio de Rosnay, identificando las vinculaciones entre dichos problemas y atacándolas en conjunto. De esta manera, se identifican algunas similitudes entre el COVID-19, el cambio climático, la contaminación ambiental, la salud de las personas, la pérdida de biodiversidad y la recesión económica; planteando la viabilidad de una solución verde ante ellos, tal como algunos países europeos lo vienen proponiendo.
Velocity correlations in dense granular flows

description: Velocity fluctuations of grains flowing down a rough inclined plane are experimentally studied. The grains at the free surface exhibit fluctuating motions, which are correlated over few grains diameters. The characteristic correlation length is shown to depend on the inclination of the plane and not on the thickness of the flowing layer. This result strongly supports the idea that dense granular flows are controlled by a characteristic length larger than the particle diameter.

description: Producers have a wide variety of risk management instruments available. How do producers make a choice of risk management instruments? Using the recently developed choice bracketing framework, we examine what risk management strategies producers use and identify the factors that drive their risk management decisions. Our results identify that producers use a wide variety of combinations of risk management instruments and that they bracket their choices into sets of alternative risk management instruments. Using multinomial logit models to estimate the choice process provides information about the factors that influence producers' decision making. The results show that broad bracketing producers use different risk management instruments than narrow bracketers. Policy makers and financial institutions can improve the performance of their programs and products when they are able to identify the bracketing level of segments of producers.

description: Using event-driven molecular dynamics we study one- and two-dimensional ballistic annihilation. We estimate exponents $ξ$ and $γ$ that describe the long-time decay of the number of particles ($n(t)\sim t^{-ξ}$) and of their typical velocity ($v(t)\sim t^{-γ}$). To a good accuracy our results confirm the scaling relation $ξ+ γ=1$. In the two-dimensional case our results are in a good agreement with those obtained from the Boltzmann kinetic theory.
