description: We consider the linear growth and fragmentation equation with general coefficients. Under suitable conditions, the first eigenvalue represents the asymptotic growth rate of solutions, also called \emph{fitness} or \emph{Malthus coefficient} in population dynamics ; it is of crucial importance to understand the long-time behaviour of the population. We investigate the dependency of the dominant eigenvalue and the corresponding eigenvector on the transport and fragmentation coefficients. We show how it behaves asymptotically as transport dominates fragmentation or \emph{vice versa}. For this purpose we perform suitable blow-up analysis of the eigenvalue problem in the limit of small/large growth coefficient (resp. fragmentation coefficient). We exhibit possible non-monotonic dependency on the parameters, conversely to what would have been conjectured on the basis of some simple cases.

The thick-thin decomposition and the bilipschitz classification of normal surface singularities

description: We describe a natural decomposition of a normal complex surface singularity $(X,0)$ into its "thick" and "thin" parts. The former is essentially metrically conical, while the latter shrinks rapidly in thickness as it approaches the origin. The thin part is empty if and only if the singularity is metrically conical; the link of the singularity is then Seifert fibered. In general the thin part will not be empty, in which case it always carries essential topology. Our decomposition has some analogy with the Margulis thick-thin decomposition for a negatively curved manifold. However, the geometric behavior is very different; for example, often most of the topology of a normal surface singularity is concentrated in the thin parts. By refining the thick-thin decomposition, we then give a complete description of the intrinsic bilipschitz geometry of $(X,0)$ in terms of its topology and a finite list of numerical bilipschitz invariants.

description: Die vorliegende Masterarbeit beschäftigt sich mit der Mutter-Tochter-Beziehung in Ruth Klügers Autobiographien „weiter leben. Eine Jugend“ und „unterwegs verloren. Erinnerungen“, wobei der Fokus auf ersterer liegt, da die Beziehung hierbei in einer Retrospektive teils ausgiebig entfaltet wird. Das konfliktäre und komplexe Verhältnis zwischen Mutter und Tochter ist folglich der zentrale Gegenstand der Masterarbeit. Zusätzlich wird auch die Beziehung zum Vater sowie die Bedeutung von Freundinnen in die wissenschaftliche Untersuchung miteinbezogen. Das komplexe Beziehungsgeflecht zwischen Ruth Klüger, ihrem Vater und den Freundinnen übernimmt dabei die Aufgabe einer Reflexionsebene zur Beziehung mit Klügers Mutter. Die Weiterentwicklung von der Tochter hin zu einer Mutter soll letzten Endes zeigen, dass die Beziehung zwischen Ruth und Alma Klüger wesentliche Auswirkungen auf Klügers eigene Mutterrolle und die Beziehung zu ihren beiden Söhnen hatte.
Meta-analysis of family-centered positive behaviour support with families of children with developmental disabilities and problem behaviour
Creators: name: Gao, Xin
Publisher: name: University of British Columbia
Year: 2020

description: Children with developmental disabilities often engage in problem behaviour. Problem behaviour has a pervasive and disruptive effect on children’s development and family quality of life. Family-centered Positive Behaviour Support (FCPBS) integrates core features of a positive behaviour support approach (e.g., functional assessment, multicomponent behaviour support plan, contextual fit) and family centered service delivery (e.g., family as unit of attention, collaborative partnership, family empowerment) into a behavioural support service delivery model that aims to improve child behaviour and child and family quality of life. The primary purpose of this study was to conduct a meta-analysis to examine the overall effect of FCPBS across 30 included studies published between 1997 to 2019. The secondary purpose was to evaluate the rigor of the 30 included studies based on What Works Clearinghouse (WWC) design and evidence standards for single case research, and to determine if FCPBS meets criteria necessary to be categorized as an empirically supported treatment (EST). In addition, a moderator analysis was conducted to determine whether there were effect size differences across the moderating variables of age, gender, disability category and WWC rigor evaluation. Result showed that FCPBS is effective at reducing problem behaviour of children with developmental disabilities and increasing their appropriate behavior and/or positive engagement. Result also showed that 12 of the 30 included FCPBS studies (40%) met WWC design and evidence standards. The WWC 5-3-20 criteria for an EST indicated that the first two criterion were met (i.e., 12 studies across 6 research groups and 7 locations) but the third criterion was approached but not met, indicating that FCPBS is an emerging rather than established EST. Results are discussed in terms of relation to the literature, limitations and future directions.
Decoherence and entanglement degradation of a qubit-qutrit system in non-inertial frames

description: We study the effect of decoherence on a qubit-qutrit system under the influence of global, local and multilocal decoherence in non-inertial frames. We show that the entanglement sudden death can be avoided in non-inertial frames in the presence of amplitude damping, depolarizing and phase damping channels. However, degradation of entanglement is seen due to Unruh effect. It is shown that for lower level of decoherence, the depolarizing channel degrades the entanglement more heavily as compared to the amplitude damping and phase damping channels. However, for higher values of decoherence parameters, amplitude damping channel heavily degrades the entanglement of the hybrid system. Further more, no ESD is seen for any value of Rob's acceleration.

High Rate Lithium Air Batteries Enabled by Redox Mediator Additives
Creators: name: Rastegar, Sina
Publisher: name: University of Illinois at Chicago
Year: 2024

description: The global energy demand has been predicted to increase by one-third during next few decades. This demand largely relies on the fossil fuels that are limited and detrimental to the environment by producing CO2 which leads to the global warming (greenhouse effect). Therefore, it is urgent to develop advanced environmentally friendly and inexpensive energy conversion and storage systems to solve the energy demand.
In this field, we are faced with a challenge caused by the gradual depletion of fossil fuels. To secure a safe and sustainable energy supply, renewable energies such as solar and wind have been developed. However, these energies are limited and intermittent, but rechargeable batteries are the most promising candidates to meet these needs thanks to their high energy density and high energy efficiency. Among them, the lithium-ion battery (LIB), which is operated based on intercalation mechanism, has played an important role in our society in the past two decades. However, the low energy density of LIB has restricted its application as the energy supplier of next generation. Development of metal–air battery has provided a solution benefitting from its much higher theoretical energy density than that of LIB. In contrast to the closed system of LIB, the metal–air battery are featured with an open cell structure, in which the cathode active material, oxygen, coming from ambient atmosphere. In general, the metal–air battery consists of metal anode, electrolyte, and porous cathode. Metals such as Li, Na, Fe, Zn, etc. can be used as anode materials in metal–air batteries.
title: "Dialekt"-Handel(n)
Creators: name: Muhr, Susanna
Year: 2023

description: Die vorliegende Masterarbeit untersucht mit 'Dialekt'-Motiven bedruckte T-Shirts. Ausgehend von der Frage, warum bzw. wie solche Kleidungsstücke als eigenständige Produkte funktionieren und welche Prozesse an dieser 'dialektalen' Warenwerdung beteiligt sind, werden zwei Thesen forschungsleitend: Die erste, von Barbara Johnstone übernommene These bezieht sich auf Asif Agha und sieht soziale Registrierungsprozesse, in denen 'dialektale' Sprachformen mit positiv bewerteten Vorstellungen verknüpft werden, zugleich als Voraussetzung und Folgeerscheinung solcher Produkte. Die zweite These, wonach sich Käufer*innen durch das Tragen der Kleidung zum sozial registrierten 'Dialekt'-Gebrauch positionieren, betrifft mit dem Kauf der Produkte einhergehende, analytisch erschließbare metapragmatische Handlungen. Theoretisch-methodologisch ist die Arbeit somit von einer dezidiert metapragmatischen Perspektive bestimmt: Als zentrale theoretische Grundlage dient das Modell der metapragmatischen Positionierung von Jürgen Spitzmüller, welches das Stance-Dreieck nach Du Bois auf Sprachgebrauch und soziale Register spezifiziert. Damit kann das Phänomen der 'Dialekt'-Kleidung als eine unauflösbare Verflechtung von metapragmatischen (Positionierungs-)Akten und Praktiken der Kommodifizierung betrachtet werden. Auf dieser theoretischen Basis wird in der Folge eine Momentaufnahme des 'Dialekt'-Handel(n)s erstellt, indem T-Shirt-Motive, Website und Facebook-Beiträge eines größeren österreichischen Webshops eingehend multimodal und metapragmatisch analysiert werden. Hierbei stehen (metapragmatische) Positionierungen beider Akteur*innen-Seiten – Verkäufer*innen und Käufer*innen – im Fokus. Die Untersuchung zeichnet so nicht nur ein detailliertes Bild von positiv bewerteten 'dialektal-österreichischen' Personen- und Handlungstypen, sie zeigt auch auf, wie Akteur*innen sich selbst und andere entlang dieser Vorstellungen positionieren, indem sie 'Dialekt' in konkreten Äußerungen realisieren.
title: Validierung eines Itempools zur Erfassung der Grundemotionen bei Kindergartenkindern anhand von Fotos eines Buben

description: Die vorliegende Arbeit befasst sich mit der inhaltlichen und konvergenten Validierung neu erstellter Items. Bei den Items handelt es sich um Fotos eines Buben, welcher die Emotionen Freude, Ärger, Trauer, Ekel, Überraschung und Neutral in seinem Ausdruck zeigte. Die Items wurden im Zuge einer anstehenden Überarbeitung des Subtests Fotoalbum aus dem Wiener Entwicklungstest erstellt und sollen der psychologisch-diagnostischen Überprüfung der emotionalen Fertigkeiten von Kindern in einem Alter von drei bis sechs Jahren dienen. Zur Überprüfung der Items wurden die neuen Items gemeinsam mit dem aktuellen Subtest Fotoalbum und einem weiteren Validierungsinstrument insgesamt 54 Kindern aus unterschiedlichen Wiener Kindergärten vorgelegt. Alle Erhebungen fanden vormittags, in einem Zeitraum vom 22.08.2022 bis 18.11.2022, in den Räumlichkeiten der jeweiligen Kindergärten statt. Die inhaltliche Gültigkeit kann durch die Auseinandersetzung mit den aktuellen wissenschaftlichen Erkenntnissen und durch die Erstellung der Items sichergestellt werden. Die konvergente Validität und Alterseffekte können lediglich bei den Items Freude 1und 2 nachgewiesen werden. Items der Emotionen Ärger, Ekel, Überraschung, Neutral und Trauer weisen keine konvergente Gültigkeit und Alterseffekte auf. Die Limitationen der Erhebung und Ausblicke auf zukünftige Projekte werden diskutiert.
description: The aim of the study was to examine the content and convergent validity of newly created items. The items are pictures that show the emotional expressions: joy, anger, disgust, surprise, neutral and sadness of a boy. In the course of an upcoming revision of the subtest “Fotoalbum”, from the “Wiener Entwicklungstest” the items were created to examine the emotional knowledge of children aged three to six years. Together with the Fotoalbum and another validation instrument, the items were presented to a total of 54 children from different Viennese nursery schools. Testing took place in the morning in a period from 22.08.2022 to 18.11.2022 on the premises of the respective nursery schools. The validity of the items’ content can be ensured by current scientific findings and item development. Convergent validity and age effects can only be proven for the items joy 1 and 2. The research outcome reveals that the Items with the emotional expression of anger, disgust, surprise, neutrality and sadness show no convergent validity and age effects. The limitations of this study and implications for further studies are being discussed.

description: Elementary excitations of an S = 1/2 antiferromagnetic Heisenberg chain KCuGaF6 were investigated through specific heat and electron spin resonance (ESR) measurements. In this compound, a staggered field is induced perpendicular to the external field because of the alternating g tensor and the Dzyaloshinsky-Moriya interaction with an alternating D vector. Such a spin system can be mapped onto the quantum sine-Gordon (SG) model, when subjected to the external magnetic field. Specific heat shows clear evidence of the field-induced gap, which is related to the elementary excitations, solitons and breathers, characteristic of the quantum SG model. q = 0 excitations originated from solitons and breathers were directly observed by high-frequency high-field ESR. These experimental results are well described by the quantum SG field theory.

Deep water renewal during wintertime stratification in a deep, freshwater, thermobarically stratified lake
Creators: name: Smith, Lydia
Publisher: name: University of British Columbia
Year: 2020

description: Thermobarically stratified Quesnel Lake shows relatively high rates of hypolimnetic mixing and transport over its winter (inverse) stratification period. A decade-long data set reveals annual winter trends of warming and cooling at 500 m depth, field measurements record increasing hypolimnetic oxygen levels between fall and summer, demonstrating regular ventilation. This research describes processes responsible for the ventilation of the deep hypolimnetic water of Quesnel Lake. Temperature records from moored instruments, and conductivity, temperature, and depth (CTD) profiles were processed to assess transport and mixing in the lake. Local weather stations, regional government data, and modelled data were used to calculate atmospheric forcing at the surface of the lake. These data were compared to find links between atmospheric events and deep-water behavior over the winter of 2006-2007. The results show that the deep water is ventilated by wintertime thermobaric instabilities induced by baroclinic seiche, and by a prolonged spring turnover. Turbulent mixing from seiche homogenizes the bottom water (within 0.02ºC) to a maximum height of ~400 m above the lake bottom. Deepening of the surface mixed layer is aided by the homogenized bottom layer to produce a full spring turnover. This study supports previous research on Quesnel Lake, demonstrating that wind forcing is an effective mixing and transport mechanism even in the deepest region of the lake.

description: We study the issues of scaling and universality in spectral and transport properties of the infinite dimensional particle--hole symmetric (half-filled) Hubbard model within dynamical mean field theory. One of the simplest and extensively used impurity solvers, namely the iterated perturbation theory approach is reformulated to avoid problems such as analytic continuation of Matsubara frequency quantities or calculating multi-dimensional integrals, while taking full account of the very sharp structures in the Green's functions that arise close to the Mott transitions and in the Mott insulator regime. We demonstrate its viability for the half-filled Hubbard model. Previous known results are reproduced within the present approach. The universal behavior of the spectral functions in the Fermi liquid regime is emphasized, and adiabatic continuity to the non-interacting limit is demonstrated. The dc resistivity in the metallic regime is known to be a non-monotonic function of temperature with a `coherence peak'. This feature is shown to be a universal feature occurring at a temperature roughly equal to the low energy scale of the system. A comparison to pressure dependent dc resistivity experiments on Selenium doped NiS$_2$ yields qualitatively good agreement. Resistivity hysteresis across the Mott transition is shown to be described qualitatively within the present framework. A direct comparison of the thermal hysteresis observed in V$_2$O$_3$ with our theoretical results yields a value of the hopping integral, which we find to be in the range estimated through first-principle methods. Finally, a systematic study of optical conductivity is carried out and the changes in absorption as a result of varying interaction strength and temperature are identified.

description: Die schulische Inklusion von Schüler*innen im Autismus-Spektrum rückt seit dem Inkrafttreten der UN-Behindertenrechtskonvention verstärkt in den Fokus des Interesses. Dennoch zeigen sich sowohl Lücken in Bezug auf Gelingensfaktoren für die Umsetzung der Beschulung als auch in der individuellen Sichtweise dieser Schüler*innen. Die vorliegende Masterarbeit setzt an dieser Stelle an und nimmt den Blickwinkel von Betroffenen ins Zentrum des Forschungsinteresses. Es wurden problemzentrierte Interviews nach Witzel (1985) mit Erwachsenen im Autismus-Spektrum geführt, die mithilfe der qualitativen Inhaltsanalyse nach Mayring (2015) ausgewertet wurden. Anhand der Ergebnisse wird ersichtlich, dass für ein positives Schulerleben von Schüler*innen im Autismus-Spektrum das Fachwissen der Schule und deren Lehrkräfte eine zentrale Rolle einnimmt. Dieses ist maßgeblich, um eine reizarme und strukturierte Lernumgebung zu schaffen, in der auf die Bedürfnisse der Individuen eingegangen wird und ein wertschätzender Umgang im Mittelpunkt steht. Darüber hinaus ist von Bedeutung, dass Schüler*innen im Autismus-Spektrum Strategien zur Selbstregulation bei der sensorischen Verarbeitung der Umgebungsreize kennenlernen, damit sie an ihrer schulischen Umgebung teilhaben können und positive Schulerfahrungen sammeln.
description: The inclusion of students on the autism spectrum in schools has become the focus of attention since the UN Convention on the Rights of Persons with Disabilities came into force. However, little research has focused on schooling success factors for students in the autism spectrum as well as on their individual school experiences. This master's thesis addresses those gaps in the literature and focuses on the perspective of those who are affected. Problem-centered interviews according to Witzel (1985) were conducted with adults in the autism spectrum, which were evaluated with the help of qualitative content analysis according to Mayring (2015). The results show that the expertise of schools and teachers play a central role in the positive school experience of students on the autism spectrum. This is essential in order to create a low-stimulus and structured learning environment in which the needs of the individuals are addressed, and an appreciative approach is put in center. In addition, it is important that students on the autism spectrum learn about their strategies for self-regulation in sensory processing of environmental stimuli, so that they can participate in their school environment and gain positive school experiences.

description: Although recent measurements of the shower profiles of ultra-high energy cosmic rays suggest that they are largely initiated by heavy nuclei, such conclusions rely on hadronic interaction models which have large uncertainties. We investigate an alternative test of cosmic ray composition which is based on the observation of ultra-high energy photons produced through cosmic ray interactions with diffuse low energy photon backgrounds during intergalactic propagation. We show that if the ultra-high energy cosmic rays are dominated by heavy nuclei, the flux of these photons is suppressed by approximately an order of magnitude relative to the proton-dominated case. Future observations by the Pierre Auger Observatory may be able to use this observable to constrain the composition of the primaries, thus providing an important cross-check of hadronic interaction models.

Characterization and functional analysis of two redundant MAPKKKs in plant immunity
Creators: name: Zhang, Qian
Publisher: name: University of British Columbia
Year: 2023

description: Mitogen-activated protein kinase (MAPK) cascades are conserved signaling modules that transduce and amplify signals from upstream receptors in eukaryotes. In Arabidopsis, two MAP kinase cascades are activated upon treatment of flg22, a conserved peptide of 22 amino acids within the N terminus of bacteria flagellin. One cascade is composed of MEKK1-MKK1/2-MPK4. The other one is composed of MKK4/5-MPK3/6 and previously unknown MAPKKK(s). How signals are transduced to MAP kinase cascades was also not very clear. My Ph.D. research focuses on identification of the previously unknown MAPKKK(s) upstream of MKK4/MKK5-MPK3/MPK6 module and characterization of this MAP kinase cascade in plant immunity. It is known that YDA-MKK4/5-MPK3/6 cascade regulates stomatal development. I hypothesized that the close homologues of YDA, MAPKKK3 and MAPKKK5, function upstream of MKK4/MKK5-MPK3/MPK6 to regulate plant immunity. The mapkkk3 mapkkk5 double mutant was found to have significantly reduced MPK3 and MPK6 activation upon multiple elicitor treatment including flg22, suggesting that MAPKKK3 and MAPKKK5 are required for multiple elicitor-induced MPK3/MPK6 activation. The double mutant also shows enhanced susceptibility towards virulent pathogens, reduced cell death and enhanced susceptibility towards avirulent pathogens, suggesting that these two MAPKKKs are required for pathogen resistance. Using E.coli expressed proteins, MAPKKK3-MKK5-MPK6 cascade was reconstituted in vitro, biochemically confirming that MAPKKK3 is upstream of MKK5 and MPK6. Kinase assays using different mutant versions of MAPKKK3 protein show that the kinase domain and C terminal domain but not the N terminal regulatory domain of MAPKKK3 is required for signaling. Previously, PCRK1 (Pattern-triggered immunity Compromised Receptor-like cytoplasmic Kinase 1) and PCRK2 were shown to interact with flg22 receptor and the pcrk1 pcrk2 double mutant shows modestly reduced flg22-induced MPK3/MPK6 activation. Co-Immunoprecipitation and biotinylation assays using transient expressed proteins in Nicotiana benthaminana showed that MAPKKK3 and MAPKKK5 interact with PCRK2, suggesting PCRK2 may transduce signal from flg22 receptor to MAPKKK3/MPKKK5. Altogether, studies in this dissertation identified two MAPKKKs functioning upstream of MKK4/5-MPK3/6, characterized the roles of this MAP kinase cascade in immunity and provided insight on signal transduction from the flg22 receptor to this MAP kinase cascade.

description: Historische Spiele können auf eine lange Historie zurückblicken. Die ersten historischen Spiele beschäftigten sich mit Kriegen oder Epochen. Ein historisches Spiel über den Ersten Weltkrieg, mit dem Titel Valiant Hearts: The Great War wird in dieser Arbeit präsentiert und untersucht. Das Spiel wurde von Ubisoft Montpellier entwickelt. Mittels einer empirischen Untersuchung soll eine Steigerung der historischen Kompetenzen durch das Spielen von Valiant Hearts: The Great War bei den Schülerinnen und Schülern festgestellt werden. Diese Untersuchung fand in drei AHS-Schulklassen statt. Hierbei wurde folgende Forschungsfrage gestellt: Wie beeinflusst das Spielen von historischen digitalen Spielen das Geschichtsbewusstsein der der Spielerinnen und Spieler? Das Ziel ist ein besseres Verständnis, wie historische digitale Spiele das Geschichtsbewusstsein der Spielerinnen und Spieler beeinflussen. Die quantitative Analyse der Antworten vor und nach dem Spielen sollen das historische Wissen, die Wahrnehmungen sowie die Einschätzungen der Schülerinnen und Schüler erheben. Die Ergebnisse der Analyse konnten eine Kompetenzsteigerung durch das Spielen belegen. Die Grafiken zeigen einen signifikanten Unterschied zwischen der Pre- und Post-Testung. Für eine klare Aussage im Sinne der empirischen Sozialforschung waren das Sample und die Gesamtspieldauer allerdings zu gering

description: Graphene nanoribbons have attracted attention for their novel electronic and spin transport properties1-6, and because nanoribbons less than 10 nm wide have a band gap that can be used to make field effect transistors. However, producing nanoribbons of very high quality, or in high volumes, remains a challenge. Here, we show that pristine few-layer nanoribbons can be produced by unzipping mildly gas-phase oxidized multiwalled carbon nanotube using mechanical sonication in an organic solvent. The nanoribbons exhibit very high quality, with smooth edges (as seen by high-resolution transmission electron microscopy), low ratios of disorder to graphitic Raman bands, and the highest electrical conductance and mobility reported to date (up to 5e2/h and 1500 cm2/Vs for ribbons 10-20 nm in width). Further, at low temperature, the nanoribbons exhibit phase coherent transport and Fabry-Perot interference, suggesting minimal defects and edge roughness. The yield of nanoribbons was ~2% of the starting raw nanotube soot material, which was significantly higher than previous methods capable of producing high quality narrow nanoribbons1. The relatively high yield synthesis of pristine graphene nanoribbons will make these materials easily accessible for a wide range of fundamental and practical applications.

description: We present metallicity distribution functions (MDFs) for the central regions of eight dwarf satellite galaxies of the Milky Way: Fornax, Leo I and II, Sculptor, Sextans, Draco, Canes Venatici I, and Ursa Minor. We use the published catalog of abundance measurements from the previous paper in this series. The measurements are based on spectral synthesis of iron absorption lines. For each MDF, we determine maximum likelihood fits for Leaky Box, Pre-Enriched, and Extra Gas (wherein the gas supply available for star formation increases before it decreases to zero) analytic models of chemical evolution. Although the models are too simplistic to describe any MDF in detail, a Leaky Box starting from zero metallicity gas fits none of the galaxies except Canes Venatici I well. The MDFs of some galaxies, particularly the more luminous ones, strongly prefer the Extra Gas Model to the other models. Only for Canes Venatici I does the Pre-Enriched Model fit significantly better than the Extra Gas Model. The best-fit effective yields of the less luminous half of our galaxy sample do not exceed 0.02 Z_sun, indicating that gas outflow is important in the chemical evolution of the less luminous galaxies. We surmise that the ratio of the importance of gas infall to gas outflow increases with galaxy luminosity. Strong correlations of average [Fe/H] and metallicity spread with luminosity support this hypothesis.

description: We have investigated the impact of the $^{14}N(p,γ)^{15}O$ reaction rate recently redetermined by the LUNA experiment, on the shell H-burning and core He-burning phases of low-mass, metal poor stellar models. The new reaction rate has small but noticeable effects, the largest one being a $\sim$7-8\% reduction of the red giant branch lifetimes. To different degrees, the lifetimes and luminosities of horizontal branch models, the mass of the stellar models evolving within the RR Lyrae instability strip, the luminosity of the red giant branch luminosity function bump, the theoretical calibrations of the R-parameter and tip of the red giant branch luminosity are also affected. Predictions for the tip of the red giant branch luminosity, in particular, are in very good agreement with the currently available empirical constraints.

description: We discuss the dependence of set-valued dynamical systems on parameters. Under mild assumptions which are often satisfied for random dynamical systems with bounded noise and control systems, we establish the fact that topological bifurcations of minimal invariant sets are discontinuous with respect to the Hausdorff metric, taking the form of lower semi-continuous explosions and instantaneous appearances. We also characterise these transitions by properties of Morse-like decompositions.

description: We estimate the sensitivity to nano-Hertz gravitational waves of pulsar timing experiments in which two highly-stable millisecond pulsars are tracked simultaneously with two neighboring radio telescopes that are referenced to the same time-keeping subsystem (i.e. "the clock"). By taking the difference of the two time-of-arrival residual data streams we can exactly cancel the clock noise in the combined data set, thereby enhancing the sensitivity to gravitational waves. We estimate that, in the band ($10^{-9} - 10^{-8}$) Hz, this "interferometric" pulsar timing technique can potentially improve the sensitivity to gravitational radiation by almost two orders of magnitude over that of single-telescopes. Interferometric pulsar timing experiments could be performed with neighboring pairs of antennas of the forthcoming large arraying projects.

description: This paper introduces a novel indexing and access method, called Feature- Based Adaptive Tolerance Tree (FATT), using wavelet transform is proposed to organize large image data sets efficiently and to support popular image access mechanisms like Content Based Image Retrieval (CBIR).Conventional database systems are designed for managing textual and numerical data and retrieving such data is often based on simple comparisons of text or numerical values. However, this method is no longer adequate for images, since the digital presentation of images does not convey the reality of images. Retrieval of images become difficult when the database is very large. This paper addresses such problems and presents a novel indexing technique, Feature Based Adaptive Tolerance Tree (FATT), which is designed to bring an effective solution especially for indexing large databases. The proposed indexing scheme is then used along with a query by image content, in order to achieve the ultimate goal from the user point of view that is retrieval of all relevant images. FATT indexing technique, features of the image is extracted using 2-dimensional discrete wavelet transform (2DDWT) and index code is generated from the determinant value of the features. Multiresolution analysis technique using 2D-DWT can decompose the image into components at different scales, so that the coarest scale components carry the global approximation information while the finer scale components contain the detailed information. Experimental results show that the FATT outperforms M-tree upto 200%, Slim-tree up to 120% and HCT upto 89%. FATT indexing technique is adopted to increase the efficiently of data storage and retrieval.

title: "Optimistisch zu denken ist kriminell" - Kafka und Beckett als Zeugen von Adornos negativer Philosophie
Creators: name: Sichera, Christian
Year: 2023

description: Adornos Philosophie ist eine Philosophie der Negativität. Ihr Ausgangspunkt ist eine Welt, welche, so wie sie ist, nicht sein soll. Dies wird für Adorno bezeugt durch Erfahrungen von absoluter Negativität wie Auschwitz, aber auch durch individuelle Erfahrungen von Glück, welche im Wesentlichen keine unmittelbar positiven, sondern vielmehr negativ vermittelte sind. Das Glück, das in ihnen liegt ist, ist ein Standhalten gegenüber dem, was sich für Adorno intuitiv als Negatives zeigen kann. Im Besonderen erfahrbar wird dies in der Kunst, in der ästhetischen Erfahrung. Hier zeigt sich, wie sehr unser Erkenntnisprozess ein gesellschaftlich geformter ist und inwiefern dieser sich auch anders gestalten könnte. Die Wahrnehmung der Welt ist nicht auf begriffliches Denken eingeschränkt, sondern geht weit darüber hinaus. Die Kunst kann uns das exemplarisch vormachen, weil das, was wir an dieser erfahren, mehr ist, als das, was wir über diese sagen können. Ihr Rätselcharakter verunmöglicht es, das, was uns ein Kunstwerk erzählt, mit eigenen Worten wiederzugeben. Kafka und Beckett sind für Adorno deswegen von so hoher Bedeutung, weil er in ihnen das verwirklich sieht, wohin er mit seiner Philosophie möchte bzw. von wo diese ihren Ausgang nimmt. Es ist erfahrbar gemachte Negativität. Wie sich diese Erfahrung nun für die Leserschaft gestaltet und inwiefern gerade in dieser Erfahrung so etwas wie Hoffnung durchscheinen kann wird zu zeigen sein.

description: We present a computer library for the numerical evaluation of colour-ordered n-gluon amplitudes at one-loop order in pure Yang-Mills theory. The library uses the recently developed technique of generalised unitarity. Running in double precision the library yields reliable results for up to 14 gluons with only a small fraction of events requiring a re-evaluation using extended floating point arithmetic. We believe that the library presented here provides an important contribution to future LHC phenomenology. The program may also prove useful in cross checking results obtained by other methods. In addition, the code provides a sample implementation which may serve as a starting point for further developments.

description: We consider an energy conserving linear dynamics that we perturb by a Glauber dynamics with random site dependent intensity. We prove hydrodynamic limits for this non-reversible system in random media. The diffusion coefficient turns out to depend on the random field only by its statistics. The diffusion coefficient defined through the Green-Kubo formula is also studied and its convergence to some homogenized diffusion coefficient is proved.
