description: Consider in the phase space of classical mechanics a Radon measure that is a probability density carried by the graph of a Lipschitz continuous (or even less regular) vector field. We study the structure of the push-forward of such a measure by a Hamiltonian flow. In particular, we provide an estimate on the number of folds in the support of the transported measure that is the image of the initial graph by the flow. We also study in detail the type of singularities in the projection of the transported measure in configuration space (averaging out the momentum variable). We study the conditions under which this projected measure can have atoms, and give an example in which the projected measure is singular with respect to the Lebesgue measure and diffuse. We discuss applications of our results to the classical limit of the Schrödinger equation. Finally we present various examples and counterexamples showing that our results are sharp.

description: In higher education institutions, in the process of preparing future teachers for their future professional activities, specialized and specialized subjects are taught. The subjects taught in the direction of technological education prepare future teachers for this profession by providing information about these subjects. This is done in the process of education. As is known, education is a two-way process, covering the activities of educators and learners. The effectiveness of this process is largely determined by the correct orientation of the activities of educators and learners. It is customary to call and name this path in pedagogical science as teaching methods. Namely, teaching methods are a way of carrying out activities that lead to achieving the intended goal.

description: Bei der Pflege stillgelegter Flächen sollen für eine gute Verrottung erforderliche kurze Häcksel bei möglichst geringem Leistungsbedarf und mit hoher Schlagkraft erzielt werden. Der Vorteil des Häckslerbetriebs im Front-Anbau (keine langen Stoppel in der Fahrspur) muss durch zusätzliche Motorleistung erkauft werden. Der gleichzeitige Einsatz von Schlegelhäckslern im Front- und Heck/Seiten-Anbau erhöht die Schlagkraft, aber auch den Leistungsbedarf. Werden statt der üblicherweise auf dem Betrieb vorhandenen Häcksler mit Plattenschlegel solche mit Y-Schlegeln eingesetzt, so reduziert dies die erforderliche Motorleistung, ohne den gewünschten Arbeitseffekt „kurze Häcksel“zu beeinträchtigen.

description: This work presents methods of controlling the density of self-assembled CdTe quantum dots (QDs) grown by molecular beam epitaxy. Two approaches are discussed: increasing the deposition temperature of CdTe and the reduction of CdTe layer thickness. Photoluminescence (PL) measurements at low temperature confirms that both methods can be used for significant reduction of QDs density from 10$^{10}$QD/cm$^2$ to 10$^7$-10$^8$QD/cm$^2$. For very low QDs density, identification of all QDs lines observed in the spectrum is possible.

description: We show how to underapproximate the procedure summaries of recursive programs over the integers using off-the-shelf analyzers for non-recursive programs. The novelty of our approach is that the non-recursive program we compute may capture unboundedly many behaviors of the original recursive program for which stack usage cannot be bounded. Moreover, we identify a class of recursive programs on which our method terminates and returns the precise summary relations without underapproximation. Doing so, we generalize a similar result for non-recursive programs to the recursive case. Finally, we present experimental results of an implementation of our method applied on a number of examples.

Theory of absorption spectrum in the nonequilibrium steady state of superconductors under microwave irradiation
Creators: name: Jujo, Takanobu
Publisher: name: arXiv
Year: 2023
Subjects: subject: Superconductivity (cond-mat.supr-con)
subject: FOS: Physical sciences

description: We discuss the absorption spectrum of dirty s-wave superconductors in the nonequilibrium steady state under a homogeneous and monochromatic microwave. In this state, there exists a finite density of states at lower energies than the superconducting gap, and the distribution function is also defined in this energy region. Because of the reduction of the distribution function below the superconducting gap, the absorption by thermally excited quasiparticles is suppressed in the nonequilibrium state compared with that in the equilibrium case. This is in contrast to the cases of the gap function and the absorption by direct excitation, to which the variation of the distribution function above the superconducting gap mainly contributes. It is also shown that amplitude modes are generated by frequency mixing of the pump wave and the probe wave, and two peaks appear in the absorption spectrum.
Nährstoffsteuerung bei der Feststoffabtrennung aus Flüssigmist

description: Mit den Regelungen der ab 1. Juli 1996 in Kraft getretenen Düngeverordnung und der zunehmenden Ausweitung von Wasserschutzgebieten (Zone II) werden die mit dem Wirtschaftsdünger je Hektar maximal auszubringenden Nährstoffmengen weiter eingeschränkt oder deren Ausbringung vollständig untersagt. Damit sind ganze Regionen mit intensiver Viehhaltung, aber auch Einzelbetriebe mit hoher Besatzdichte gezwungen, nach Möglichkeiten für eine Entlastung der Nährstoffbilanz zu suchen. ln Frage kommt neben einer nährstoffangepassten Fütterung die Feststoffabtrennung aus Flüssigmist. Ziel dieser Untersuchung ist es, durch eine Modellierung die mit den abgetrennten Phasen abgeschiedenen Nährstoffmengen unter Berücksichtigung der trenntechnischen Parameter vorauszuberechnen. Damit kann eine mögliche Steuerung der Nährstoffverlagerung bei der Trennung schon im Vorfeld beurteilt werden. Der Vergleich der Modellrechnung mit den ersten Ergebnissen aus Laboruntersuchungen zeigt bei organisch gebundenem Stickstoff und Phosphor eine gute Übereinstimmung.

Collision-model-based approach to non-Markovian quantum dynamics

description: We present a theoretical framework to tackle quantum non-Markovian dynamics based on a microscopic collision model (CM), where the bath consists of a large collection of initially uncorrelated ancillas. Unlike standard memoryless CMs, we endow the bath with memory by introducing inter-ancillary collisions between next system-ancilla interactions. Our model interpolates between a fully Markovian dynamics and the continuous interaction of the system with a single ancilla, i.e., a strongly non-Markovian process. We show that in the continuos limit one can derive a general master equation, which while keeping such features is guaranteed to describe an unconditionally completely positive and trace-preserving dynamics. We apply our theory to an atom in a dissipative cavity for a Lorentzian spectral density of bath modes, a dynamics which can be exactly solved. The predicted evolution shows a significant improvement in approaching the exact solution with respect to two well-known memory-kernel master equations.

Creators: name: Kersting, Norbert

Year: 2022
Subjects: subject: 320 Political science (Politics and government)

description: Political participation and sustainability seem to be closely intertwined. In the last few decades it can be shown that the topic of sustainability and ecological interest groups play an important role in citizen engagement, political participation, and democratic innovations at the local level. Using a participatory rhombus model of participatory democracy, different forms of participation and democratic innovations in the representative sphere, in direct democracy, in demonstrative participatory space, and finally in deliberative participatory instruments are important in the decision-making for sustainability policies. Here the paper tries to close the gap in empirical data on the perceptions of citizens and councilors on these participatory instruments. Citizens believe strongly in the importance of elections and referendums, but they extend their political repertoire and start protesting and demanding more deliberative democracy. Councilors positively perceive democratic innovations, and the councilors of the Green Party in particular strongly support new participatory instruments. However, citizens and councilors do not support all instruments in the same way.

description: We study the two-body decay of a mother particle into a massless daughter. We further assume that the mother particle is unpolarized and has a generic boost distribution in the laboratory frame. In this case, we show analytically that the laboratory frame energy distribution of the massless decay product has a peak, whose location is identical to the (fixed) energy of that particle in the rest frame of the corresponding mother particle. Given its simplicity and "invariance" under variations of the boost distribution of the mother particle, our finding should be useful for the determination of masses of mother particles. In particular, we anticipate that such a procedure will then not require a full reconstruction of this two-body decay chain (or for that matter, information about the rest of the event). With this eventual goal in mind, we make a proposal for extracting the peak position by fitting the data to a well-motivated analytic function describing the shape of such energy distribution. This fitting function is then tested on the theoretical prediction for top quark pair production and its decay and it is found to be quite successful in this regard. As a proof of principle of the usefulness of our observation, we apply it for measuring the mass of the top quark at the LHC, using simulated data and including experimental effects.

description: We study the geometry and topology of (filtered) algebra-bundles ${\bfΨ}^{\mathbb Z}$ over a smooth manifold $X$ with typical fibre $Ψ^{\mathbb Z}(Z; V)$, the algebra of classical pseudodifferential operators of integral order on the compact manifold $Z$ acting on smooth sections of a vector bundle $V$. First a theorem of Duistermaat and Singer is generalized to the assertion that the group of projective invertible Fourier integral operators ${\rm PGL}({\mathcal F}^\bullet(Z; V))$, is precisely the automorphism group, ${\rm Aut}(Ψ^{\mathbb Z}(Z; V)),$ of the filtered algebra of pseudodifferential operators. We replace some of the arguments in their paper by microlocal ones, thereby removing the topological assumption well as extending their result to sections of a vector bundle. We define a natural class of connections and B-fields the principal bundle to which ${\bfΨ}^{\mathbb Z}$ is associated and obtain a de Rham representative of the Dixmier-Douady class, in terms of the outer derivation on the Lie algebra and the residue trace of Guillemin and Wodzicki; the resulting formula only depends on the formal symbol algebra ${\bfΨ}^{\mathbb Z}/{\bfΨ}^{-\infty}.$ Examples of pseudodifferential algebra bundles are given that are not associated to a finite dimensional fibre bundle over $X.$

Close to the critical temperature, GL arises as an effective theory on the macroscopic scale. The relevant scaling limit is semiclassical in nature, and semiclassical analysis, with minimal regularity assumptions, plays an important part in our proof.

Gegenstand dieser Untersuchungen ist daher die Ermittlung des Einflusses des Gesamtwassergehaltes solcher halbtrockenen Brennstoffe auf die Emission von Schadgasen. Es zeigt sich, dass mit Ausnahme von Schwefeldioxid die Schadstoffemissionen bei erhöhten Feuchten im allgemeinen zunehmen und bei Halmgütern stärker vom Gesamtwassergehalt abhängig sind als bei Holzbrennstoffen.

A Fock space approach to Severi degrees

Subjects: subject: Algebraic Geometry (math.AG)

description: The classical Severi degree counts the number of algebraic curves of fixed genus and class passing through points in a surface. We express the Severi degrees of CP1 x CP1 as matrix elements of the exponential of a single operator M on Fock space. The formalism puts Severi degrees on a similar footing as the more developed study of Hurwitz numbers of coverings of curves. The pure genus 1 invariants of the product E x CP1 (with E an elliptic curve) are solved via an exact formula for the eigenvalues of M to initial order. The Severi degrees of CP2 are also determined by M via the (-1)^(d-1)/d^2 disk multiple cover formula for Calabi-Yau 3-fold geometries.

description: Nucleic acids are highly deformable helical molecules constantly stretched, twisted and bent in their biological functioning. Single molecule experiments have shown that double stranded (ds)-RNA and standard ds-DNA have opposite twist-stretch patterns and stretching properties when overwound under a constant applied load. The key structural features of the A-form RNA and B-form DNA helices are here incorporated in a three-dimensional mesoscopic Hamiltonian model which accounts for the radial, bending and twisting fluctuations of the base pairs. Using path integral techniques which sum over the ensemble of the base pair fluctuations, I compute the average helical repeat of the molecules as a function of the load. The obtained twist-stretch relations and stretching properties, for short A- and B-helical fragments, are consistent with the opposite behaviors observed in kilo-base long molecules.

description: Social enterprises can often help address persistent problems in rural areas of emerging economies, such as unemployment, poverty, and lack of access to information and government programs. While many social enterprises have hybrid business models with a dual performance objective of increasing both social welfare and financial returns, often, these organizations end up compromising on the social purpose for financial gain in a phenomenon known as mission drift (Cornforth, 2014; Doherty, Haugh, & Lyon, 2014; Santos, Pache, & Birkholz, 2015). Mission drift can be perceived as a problem due to organizational identity and scaling issues (Chambers, 2014), collaborative goal congruence (Kwong, Tasavori, & Cheng, 2017), or meeting investors’ expectations (Cetindamar & Ozkazanc-Pan, 2017). We investigate mission drift occurring among microentrepreneurs affiliated with a social enterprise.

title: Perspectives on love as a component of professional practice
Creators: name: Vincent, Jennifer
Publisher: name: Strathprints - University of Strathclyde
Year: 2016

description: Since children and youth are often cared for by many professionals who are trained and educated in different disciplinary traditions, it is important that child and youth care (CYC) practitioners who work alongside other professionals have knowledge of how love is understood across different disciplines. Through a review of current literature in the fields of health care, education and CYC, this article explores the perceptions of love across different fields where CYC is practised. It begins by defining love in a manner that reflects the engagement and interactions between individuals in professional and public relationships, and differentiates this from the kind of love present in private relationships. It then focuses on the ways that love is currently being talked about and practised in different professional contexts. While there is increasing openness to talk about love across the human service fields, and some similarities in the questions and assertions that are being raised, there are also differences of opinion regarding love's place in professional practice both within and across practice domains. In contemplating the varying perceptions of love, I hope to offer the reader an opportunity to be more mindful about the role of love in their own professional practice.

description: Epidemic prediction is a fundamental task for epidemic control and prevention. Many mechanistic models and deep learning models are built for this task. However, most mechanistic models have difficulty estimating the time/region-varying epidemiological parameters, while most deep learning models lack the guidance of epidemiological domain knowledge and interpretability of prediction results. In this study, we propose a novel hybrid model called MepoGNN for multi-step multi-region epidemic forecasting by incorporating Graph Neural Networks (GNNs) and graph learning mechanisms into Metapopulation SIR model. Our model can not only predict the number of confirmed cases but also explicitly learn the epidemiological parameters and the underlying epidemic propagation graph from heterogeneous data in an end-to-end manner. The multi-source epidemic-related data and mobility data of Japan are collected and processed to form the dataset for experiments. The experimental results demonstrate our model outperforms the existing mechanistic models and deep learning models by a large margin. Furthermore, the analysis on the learned parameters illustrate the high reliability and interpretability of our model and helps better understanding of epidemic spread. In addition, a mobility generation method is presented to address the issue of unavailable mobility data, and the experimental results demonstrate effectiveness of the generated mobility data as an input to our model.

description: We present an abstract machine and a reduction semantics for the lambda-calculus extended with control operators that give access to delimited continuations in the CPS hierarchy. The abstract machine is derived from an evaluator in continuation-passing style (CPS); the reduction semantics (i.e., a small-step operational semantics with an explicit representation of evaluation contexts) is constructed from the abstract machine; and the control operators are the shift and reset family. We also present new applications of delimited continuations in the CPS hierarchy: finding list prefixes and normalization by evaluation for a hierarchical language of units and products.

description: We construct a distance on the moduli space of symplectic toric manifolds of dimension four. Then we study some basic topological properties of this space, in particular, path-connectedness, compactness, and completeness. The construction of the distance is related to the Duistermaat-Heckman measure and the Hausdorff metric. While the moduli space, its topology and metric, may be constructed in any dimension, the tools we use in the proofs are four-dimensional, and hence so is our main result.

description: Sauen müssen im Reproduktionszyklus mindestens vier Wochen lang täglich freie Bewegung erhalten. Deshalb sind neue Haltungstechniken zur Gruppenhaltung von Sauen im Wartestall für Landwirte von großem Interesse. Im Wesentlichen kommen drei Verfahren in Betracht: die Gruppenhaltung mit Selbstfangfressständen, mit Abruffütterung oder mit Dribbelfütterung. Die drei Gruppenhaltungsverfahren werden hinsichtlich ihres Fütterungsprinzips, ihrer technischen Ausstattung, Arbeitswirtschaft und Wirtschaftlichkeit verglichen. Es finden sich Angaben über das Produktionsmanagement über die Gruppengröße und über die erforderliche Bestandesgröße.

Einige Programme haben die Darstellung der gegebenen oder zu erwartenden Stallklimasituationen und die Ableitung der thermodynamisch relevanten Größen zur Aufgabe. Andere werden wegen ihres nahen Bezuges zur DIN 18910 vor allem den planerischen Anforderungen gerecht und häufig als Wärmeschutzprogramme bezeichnet.

description: Large linear magnetoresistance (MR) in electron-injected p-type silicon at very low magnetic field is observed experimentally at room temperature. The large linear MR is induced in electron-dominated space-charge transport regime, where the magnetic field modulation of electron-to-hole density ratio controls the MR, as indicated by the magnetic field dependence of Hall coefficient in the silicon device. Contrary to the space-charge-induced MR effect in unipolar silicon device, where the large linear MR is inhomogeneity-induced, our results provide a different insight into the mechanism of large linear MR in non-magnetic semiconductors that is not based on the inhomogeneity model. This approach enables homogeneous semiconductors to exhibit large linear MR at low magnetic fields that until now has only been appearing in semiconductors with strong inhomogeneities.

description: We investigate the potential to improve optical tracers of cluster mass by exploiting measurements of the magnitude gap, m12, defined as the difference between the r-band absolute magnitude of the two brightest cluster members. We find that in a mock sample of galaxy groups and clusters constructed from the Bolshoi simulation, the scatter about the mass-richness relation decreases by 15-20% when magnitude gap information is included. A similar trend is evident in a volume-limited, spectroscopic sample of galaxy groups observed in the Sloan Digital Sky Survey (SDSS). We find that SDSS groups with small magnitude gaps are richer than large-gap groups at fixed values of the one-dimensional velocity dispersion among group members sigma_v, which we use as a mass proxy. We demonstrate explicitly that m12 contains information about cluster mass that supplements the information provided by group richness and the luminosity of the brightest cluster galaxy, L_bcg. In so doing, we show that the luminosities of the members of a group with richness N are inconsistent with the distribution of luminosities that results from N random draws from the global galaxy luminosity function. As the cosmological constraining power of galaxy clusters is limited by the precision in cluster mass determination, our findings suggest a new way to improve the cosmological constraints derived from galaxy clusters.

A Consistent Approach to Falsifying Lambda-CDM with Rare Galaxy Clusters

description: We consider methods with which to answer the question "is any observed galaxy cluster too unusual for Lambda-CDM?" After emphasising that many previous attempts to answer this question will overestimate the confidence level at which Lambda-CDM can be ruled out, we outline a consistent approach to these rare clusters, which allows the question to be answered. We define three statistical measures, each of which are sensitive to changes in cluster populations arising from different modifications to the cosmological model. We also use these properties to define the 'equivalent mass at redshift zero' for a cluster --- the mass of an equally unusual cluster today. This quantity is independent of the observational survey in which the cluster was found, which makes it an ideal proxy for ranking the relative unusualness of clusters detected by different surveys. These methods are then used on a comprehensive sample of observed galaxy clusters and we confirm that all are less than 2-sigma deviations from the Lambda-CDM expectation. Whereas we have only applied our method to galaxy clusters, it is applicable to any isolated, collapsed, halo. As motivation for future surveys, we also calculate where in the mass redshift plane the rarest halo is most likely to be found, giving information as to which objects might be the most fruitful in the search for new physics.

Mähdreschersimulation

description: Die Entwicklung von Mähdreschern erfordert großen experimentellen Aufwand, da die Trenneinrichtungen bereits sehr ausgereift und weitere Leistungssteigerungen nur schwer zu verwirklichen sind. ln der Simulation lassen sich dagegen die für den Betrieb wichtigen Parameter wesentlich einfacher variieren und optimieren. Grundlage bilden dabei stets geeignete mathematische Modelle der Trennprozesse. Für die Korn-Stroh-Trennung auf dem Schüttler und die Korn-Spreu-Trennung auf der Reinigungsanlage wird ein gemeinsames mathematisches Modell vorgestellt, das auf physikalischen Gesetzen beruht und gut mit den Versuchsergebnissen übereinstimmt. Damit stellt die Simulation eine Ergänzung zu experimentellen Untersuchungen dar, indem ein Teil der Versuche eingespart und bisher nicht messbare physikalische Größen bestimmt werden können.
