description: We report the realization of a spatial and spectrally tunable air-gap Fabry-Perot type microcavity of high finesse and cubic-wavelength-scale mode volume. These properties are attractive in the fields of opto-mechanics, quantum sensing and foremost cavity quantum electrodymanics. The major design feature is a miniaturized concave mirror with atomically smooth surface and radius of curvature as low as 10 micrometer produced by CO2 laser ablation of fused silica. We demonstrate excellent mode-matching of a focussed laser beam to the microcavity mode and confirm from the frequencies of the resonator modes that the effective optical radius matches the physical radius. With these small radii, we demonstrate sub-wavelength beam waists. We also show that the microcavity is sufficiently rigid for practical applications: in a cryostat at 4K, the root-mean-square microcavity length fluctuations are below 5 pm.

description: The High Energy Stereoscopic System (H.E.S.S.) is an array of five imaging atmospheric Cherenkov telescopes (IACTs) to study gamma-ray emission from astrophysical objects in the Southern hemisphere. It is the only hybrid array of IACTs, composed of telescopes with different collection areas and footprints, individually optimised for a specific energy range. Collectively, the array is most sensitive to gamma rays in the range of 100 GeV to 100 TeV. The array has been in operation since 2002 and has been upgraded with new telescopes and cameras multiple times. Recent hardware upgrades and changes in the operational procedures increased the amount of observing time, which is of key importance for time-domain science. H.E.S.S. operations saw record data taking in 2020 and 2021 and we describe the current operations with specific emphasis on system performance, operational processes and workflows, quality control, and (near) real-time extraction of science results. In light of this, we will briefly discuss the early detection of gamma-ray emission from the recurrent nova RS Oph and alert distribution to the astrophysics community.
title: Structure-Property-Correlations in HfO₂ based Memristive Devices
Creators: name: Winkler, Robert
Publisher: name: UNSPECIFIED
Year: 2024

description: This PhD research aimed to bridge information gaps in oxide electronics through synthesis, macroscopic and microscopic investigation, and device characterization. Utilizing Reactive Molecular Beam Epitaxy (RMBE) and other Physical Vapor Deposition (PVD) techniques, the study precisely fabricated high-quality semiconductor heterostructures. It focused on the development and impact of texture in thin films, particularly in memristive systems with metal-insulator-metal (MIM) structures.

Initial investigations involved 23 nm TiN₁₋ₓ thin films grown on c-cut sapphire, revealing a biaxial texture and elongated grain structure influenced by substrate miscut. Notably, TiN₁₋ₓ films with high nitrogen deficiency exhibited grain boundary dissociation, advantageous for memristive devices as an ohmic bottom electrode.

Subsequent work engineered textures in HfO₂ thin films, used as the insulating layer in MIM structures. Elevated temperature RMBE growth allowed the development of distinct (001) or (111) textures on (111) textured TiN₁₋ₓ, impacting device performance. Density functional theory (DFT) calculations linked grain boundary atomic structure to the observed variations in forming voltage (VF).

Additionally, the microstructure evolution of amorphous HfO₂ during in situ transmission electron microscopy (TEM) and 4D-scanning TEM (4D-STEM) annealing was studied. Crystallization into the monoclinic phase at 180 °C was observed, with texture development enhancing device performance by lowering the forming voltage from -6.1 V to -4.2 V.

description: The phenomenon of prefilming airblast atomization is investigated by means of shadowgraphy. The focus is on the liquid accumulation, which is attached to the trailing edge in the wake region of the prefilmer. The prefilmer is planar to facilitate the measurements, and the trailing edge thickness is 230 µm. The investigated liquid is a kerosene surrogate (Shellsol D70). The operating parameters are varied with a bulk gas velocity ranging from 20 to 100 m/s and a surface volumetric liquid flow rate ranging from 20 to 120 mm2/s. In order to statistically investigate the liquid accumulation, it is virtually split into several atomizing cells. Each cell consists of a single ligament and a surrounding liquid part. Different characteristic lengths of the atomization cells are extracted by a in-house post-process tool. The distribution of these length scales are well described by a gamma function, whose scale parameter $m$ is proportional to a Weber number based on the trailing edge thickness (We_te). However, it is observed that the parameter $m$ also varies with the liquid flow rate, independently of We_te. A two-step mechanism is proposed for the dynamics of the liquid accumulation, leading to the expression of a new length scale, which combines We_te and the liquid flow rate. It is observed that the prediction of this new length scale is in good agreement with the experiment. Hence, this new characteristic length is a good candidate for predicting the length scale of the accumulation in more general configurations.
Contrast stability and "stripe" formation in Scanning Tunnelling Microscopy imaging of highly oriented pyrolytic graphite: The role of STM-tip orientations

description: Highly oriented pyrolytic graphite (HOPG) is an important substrate in many technological applications and is routinely used as a standard in Scanning Tunnelling Microscopy (STM) calibration, which makes the accurate interpretation of the HOPG STM contrast of great fundamental and applicative importance. We demonstrate by STM simulations based on electronic structure obtained from first principles that the relative local orientation of the STM-tip apex with respect to the HOPG substrate has a considerable effect on the HOPG STM contrast. Importantly for experimental STM analysis of HOPG, the simulations indicate that local tip-rotations maintaining a major contribution of the $d_{3z^2-r^2}$ tip-apex state to the STM current affect only the secondary features of the HOPG STM contrast resulting in "stripe" formation and leaving the primary contrast unaltered. Conversely, tip-rotations leading to enhanced contributions from $m\ne 0$ tip-apex electronic states can cause a triangular-hexagonal change in the primary contrast. We also report a comparison of two STM simulation models with experiments in terms of bias-voltage-dependent STM topography brightness correlations, and discuss our findings for the HOPG(0001) surface in combination with tungsten tip models of different sharpnesses and terminations.

Optimal Settings For Amplification And Estimation Of Small Effects In Postselected Ensembles

Publisher: name: arXiv
Year: 2023
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: To describe the pre- and post-selected quantum ensembles, a complex quantity called the weak value of an operator is used. The weak value is highly controversial due to the fact that it is not bounded by the possible eigenvalues of the corresponding operator. Nevertheless, the obtaining of the anomalous weak value is regarded as a powerful technique in the quantum interferometry nowadays. Here it is shown that the postselection on a quantum system recovers a completely hidden interference effect in the measurement apparatus. Studying the interference pattern shows the optimal settings for the amplification and the parameter estimation. It also proves that the weak value is not an element of reality. Using single photons, it is investigated how a postselected photon can impart a $π$ phase shift (the peak of the amplification) to a photon interacting weakly with it in a nonlinear optical medium. The increasing of the degree of the entanglement lies behind the effectiveness of the postselection in the parameter estimation. In particular, arranging to postselect on pure entangled states can optimize the signal-to-noise ratio, allowing to achieve high-sensitive measurements using low input power.

description: Intelligent routing in networks has opened up many challenges in modelling and methods, over the past decade. Many techniques do exist for routing on such an environment where path determination was carried out by advertisement, position and near-optimum node selection schemes. In this paper, an efficient routing scheme has been proposed using genetic algorithm for a grade-based two-level node selection method. This method assumes that nodes have the knowledge of its environment and is capable of taking decision for route discovery. The data learnt from the topology which is under consideration for routing, is saved in its local memory. In this two-level node selection scheme, the route discovery operation takes place in multiple levels. At the first level, the grade based selection is applied for considering the most optimal nodes which would be fit for sending data. At the second level, the optimal path is discovered using Genetic Algorithm. The simulation result shows that faster convergence of path took place in the case of the proposed method with good fitness value, as compared to non-graded network.

description: Plastic contamination of terrestrial ecosystems and arable soils pose potentially negative impacts on several soil functions. Whereas substantial plastic contamination is now traceable in agro-landscapes, often internal-caused by the application of fertilizers such as sewage sludge, questions remain unanswered concerning what happens to the plastic after incorporation. Based on a combined surface and depth sampling approach, including density separation, fuorescence staining and ATR-FTIR or µFTIR analyses, we quantifed macro- and microplastic abundance on two agricultural felds—34 years after the last sewage sludge application. By sub-dividing the study area around sludge application sites, we were able to determine spatial distribution and spreading of plastics. Past sewage sludge application led to a still high density of macroplastics (637.12 items per hectare) on agricultural soil surfaces. Microplastic concentration, measured down to 90 cm depth, ranged from 0.00 to 56.18 particles per kg of dry soil weight. Maximum microplastic concentrations were found in regularly ploughed topsoils. After 34 years without sewage sludge application, macro- and microplastic loads were signifcantly higher on former application areas, compared to surrounding areas without history of direct sewage application. We found that anthropogenic ploughing was mainly responsible for plastic spread, as opposed to natural transport processes like erosion. Furthermore, small-scale lateral to vertical heterogeneous distribution of macro- and microplastics highlights the need to determine appropriate sampling strategies and the modelling of macro- and microplastic transport in soils.

description: Sediment management is a fundamental part of reservoir operation, but it is often complicated by metal(loid) enrichment in sediments. Knowledge concerning the sources of potential contaminants is therefore of important significance. To address this issue, the concentrations and the mobile fractions of metal(loid)s were determined in the sediments and the respective catchment areas of six reservoirs. The results indicate that reservoirs generally have a high potential for contaminated sediment accumulation due to preferential deposition of fine particles. The median values of the element-specific enrichment factor (EF) demonstrates slight enrichments of arsenic (EF: 3.4), chromium (EF: 2.8), and vanadium (EF: 2.9) for reservoir sediments. The enrichments of cadmium (EF: 8.2), manganese (EF: 3.9), nickel (EF: 4.8), and zinc (EF: 5.0) are significantly higher. This is enabled by a diffuse element release from the soils into the impounded streams, which is particularly favored by soil acidity. Leaching from the catchment soils partially enriches elements in stream sediments before their fine-grained portions in particular are deposited as reservoir sediment. We assume that this effect is of high relevance especially for reservoirs impounding small streams with forested catchments and weakly acid buffering parent material of soil formation.

description: This study explores the impact of implementing an Idea Management System (IMS) to facilitate Continuous Improvement Processes (CIP) and the Plan-Do-Check-Act (PDCA)methodology in organizations. The main focus was to determine whether IMS can improvethe ease of implementing CIP and if a web-based software provides improvement over a traditional Excel-based system by measuring various metrics which are determined in chapter 2. Additionally, this thesis answers the question of applicability of the conceptual framework for idea management by Gerlach and Brem in the context of IMS.Using Design Science an artifact, a web-based IMS for the Fraunhofer Institute, was developed and assessed. The software was evaluated via a user study involving professionals from various industries, utilizing both hard and soft metrics obtained from a structured interview process.The findings suggest that the implementation of CIP, through a IMS, have the possibility to increase profits and reduce costs, there by enhancing organizational effectiveness. Moreover,web-based software was found to provide a superior user experience, emphasizing the importance of design in software development. The user study showed a slight preference for web-based software due to its collaborative features and scalability, although the results were not unequivocal and requires further research to evaluate its efficiency across different industries.The results also show the benefits of applying the conceptual framework by Gerlach and Brem in an IMS context and the value of having PDCA as a tool for idea generation,monitoring, and implementing of ideas. However, better user experience and design improvements are required to substantiate these claims In conclusion, this thesis provides evidence of the importance of idea management frameworks in enabling CIP, suggesting that web-based software solutions should be considered for introducing idea management into organizational workflows. These findings have minor implications for organizations seeking to grow and stay competitive in their respective markets. Further research should focus on gathering hard metrics of changesin profits and costs over a medium- to long-term time period with a more varied group of organizations.

description: Inelastic neutron scattering was employed to study the crystal-field interaction in the strontium-doped rare-earth compounds R(x)Sr(1-x)CoO(3-z) (R=Pr, Nd, Ho, and Er). Particular emphasis is laid on the effect of oxygen deficiencies which naturally occur in the synthesis of these compounds. The observed energy spectra are found to be the result of a superposition of crystal fields with different nearest-neighbor oxygen coordination at the R sites. The experimental data are interpreted in terms of crystal-field parameters which behave in a consistent manner through the rare-earth series, thereby allowing a reliable extrapolation for rare-earth ions not considered in the present work.

title: Coping With Turbulence and Safeguarding Against Authoritarianism: Polycentric Governance as a Resilience Resource
Creators: name: Behnke, Natalie
Publisher: name: Cogitatio
Year: 2024

description: Crisis management during the pandemic stimulated a bulk of analyses and debates on how states and
societies coped with this challenge. In many countries, authority migrated temporarily from parliaments to
executives and from the subnational to the national level, involving even violations of democratic and
individual rights. Such reactions are motivated by the assumption that crisis management requires prompt,
decisive, and uniform responses best delivered by a strong and centralised leadership. In contrast to this
widespread assumption, crisis and disaster management research compellingly stresses the virtues of
polycentric governance and processes based on flexibility, decentrality, and dispersed information in coping
with turbulence. In this article, a framework is proposed for analysing empirically the question of what makes
states and societies resilient. Core to this framework is the notion of resilience resources. In linking resilience
resources to properties of socio‐ecological systems and their reactions to turbulence, the resilience concept
becomes accessible to empirical analyses. The potential of the framework is illustrated by an empirical
example of the coordination of decentralised pandemic management by the German Minister‐Presidents’
Conference. This example shows how the resilience resource of polycentric governance is put into practice.
The results of the analytical, as well as the empirical part of the article, underpin the claim that resilience is
fostered by coordinated decentrality, flexible adaptation, and bricolage instead of centralisation of authority.
Fostering resilience in this sense provides also a safeguard against authoritarian tendencies.

description: Associação livre é técnica que, como diz o nome, visa fazer ligação entre uma coisa e outra de forma intuitiva, automática. Na psicanálise, consta que seria o método utilizado pelo próprio Freud, em substituição à hipnose, para que o paciente dissesse ocorre a primeira coisa que vinha à sua cabeça diante de alguma palavra ou situação. O que vem à sua mente quando lhe falo “arroz”, por exemplo? “Feijão”, respondiam muitos. Se o psicanalista pergunta a qualquer paciente atormentado no divã: “qual a primeira imagem lhe vem à mente ao ouvir“ INSS ”, dificilmente terá resposta diferente de“ fila ”. As filas se incorporaram à tradição dos órgãos públicos de assistência social - vide os extintos INAMPS e INPS - e também ao imaginário popular. Viraram peças integrantes do nosso cenário cotidiano; são usados ​​em analogias, piadas, músicas.

description: Κατά την περίοδο της πανδημίας του κορονοϊού (COVID-19), υιοθετήθηκε το εργασιακό μοντέλο της τηλεργασίας από πολλές εταιρείες παγκοσμίως, οι οποίες κλήθηκαν να προσαρμοστούν σε μία νέα πραγματικότητα. Μετά το πέρας της πανδημίας οι συνθήκες στους εργασιακούς χώρους δεν προβλέπονται ίδιες με πριν, με την παρούσα κατάσταση να αποτελεί προετοιμασία για ένα νέο μελλοντικό μοντέλο εργασίας. Στην παρούσα εργασία εξετάζεται η σχέση τηλεργασίας και άγχους των εργαζομένων, ο διαθέσιμος χρόνος για φυσική δραστηριότητα και η επίδραση του αθλητισμού στη ψυχολογία αλλά και στην εργασιακή τους απόδοση. Σκοπός της εργασίας είναι να αναδείξει την ανάγκη για τη δημιουργία ενός σύγχρονου μοντέλου εργασίας στον ελλαδικό χώρο που θα εξυπηρετεί καλύτερα τις ανάγκες των επιχειρήσεων και των εργαζομένων τους. Πιο συγκεκριμένα, προτείνεται ένα μοντέλο εργασίας, το οποίο δύναται να τροποποιηθεί ποικιλοτρόπως κατά την υιοθέτηση του από εταιρείες, και επιχειρεί να αυξήσει την εργασιακή επίδοση των εργαζομένων, λαμβάνοντας υπ’ όψιν τις ανάγκες τους για φυσική δραστηριότητα. Επίσης παρουσιάζονται διάφορες συνθήκες της τηλεργασίας που αυξάνουν το εργασιακό άγχος των υπαλλήλων και σε ποιο βαθμό, καθώς και πρακτικές που μπορούν να ακολουθήσουν οι εργαζόμενοι και οι εταιρείες για να ενισχύσουν την απόδοσή τους. Η μεθοδολογία που επιλέχθηκε για τη διεκπεραίωση της έρευνας είναι η συλλογή και αξιολόγηση των αποτελεσμάτων ενός ερωτηματολογίου, το οποίο διανεμήθηκε σε πάνω από 200 εργαζόμενους που εργάζονταν σε επιχειρήσεις που εδρεύουν στην Αττική κατά τη διάρκεια της πανδημίας. Τα αποτελέσματα που εκμαιεύθηκαν παρουσιάζουν σημαντική θετική στατιστικά συσχέτιση του εργασιακού άγχους με την τηλεργασία και σημαντικά αρνητική του εργασιακού άγχους με τη φυσική δραστηριότητα. Τέλος, αναφέρονται περιορισμοί της μελέτης, προτείνονται κατευθύνσεις για μελλοντική έρευνα και μέθοδοι πρακτικής των συμπερασμάτων.
Die Komplexität der Resozialisierung von jugendlichen Straftätern: Unterstützungsmöglichkeiten im Resozialisierungsprozess von delinquenten Jugendlichen im stationären Kontext durch Fachpersonen der sozialen Arbeit
Creators: name: Dosch, Céline
Publisher: name: Hochschule Luzern – Soziale Arbeit
Year: 2024

description: Die vorliegende Bachelorarbeit befasst sich mit der Komplexität der Resozialisierung von jugendlichen Straftätern und den vielfältigen Herausforderungen und Unterstützungsmöglichkeiten, mit denen sich Sozialarbeitende im Resozialisierungsprozess auseinandersetzen müssen. Die Arbeit bezieht sich auf männliche Jugendliche, welche persistent delinquieren und demzufolge im Rahmen des Jugendstrafrechts eine stationäre Schutzmassnahme angeordnet wurde.

Es werden sozialstrukturelle Erklärungsansätze herbeigezogen, um die Ursachen und Zusammenhänge von delinquentem Verhalten zu verstehen. Dabei wird der Lebenslage der betroffenen Jugendlichen eine besondere Achtung gegeben. Die Arbeit gliedert sich in die Betrachtung von drei Dimensionen der Resozialisierung, welche die Ebene des Individuums, des Umfelds und der Gesellschaft einschliesst. Letztere Dimension thematisiert auch strukturelle Gegebenheiten, welche auf den Resozialisierungsprozess einwirken. Was alle Dimensionen gemeinsam haben, ist die wechselseitige Beeinflussung und Abhängigkeit. Durch Erkenntnisse aus der Desistance-Forschung und dem Übergangsmanagement möchte eine positive Wirkung auf den Resozialisierungsprozess erzielt werden.

Ziel dieser Arbeit ist es, durch die Beleuchtung von multidimensionalen Zusammenhängen die Komplexität der Resozialisierung aufzuzeigen. Die bewusst breit angelegte Betrachtung soll einen umfassenden Überblick bieten und verdeutlichen, welche Faktoren den Resozialisierungsprozess hindern bzw. fördern. Dies soll nicht nur das Verständnis für die Herausforderungen erhöhen, sondern auch dazu beitragen, effektive Strategien für die Praxis zu entwickeln.

Symmetry Relations in Viscoplastic Drag Laws
Creators: name: Kamrin, Ken
name: Goddard, Joe
Publisher: name: arXiv
Year: 2014
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The following note shows that the symmetry of various resistance formulae, often based on Lorentz reciprocity for linearly viscous fluids, applies to a wide class of non-linear viscoplastic fluids. This follows from Edelen's non-linear generalization of the Onsager relation for the special case of \emph{strongly dissipative} rheology, where constitutive equations are derivable from his dissipation potential. For flow domains with strong dissipation in the interior and on a portion of the boundary this implies strong dissipation on the remaining portion of the boundary, with strongly dissipative traction-velocity response given by a dissipation potential. This leads to a non-linear generalization of Stokes resistance formulae for a wide class of viscoplastic fluid problems. We consider the application to non-linear Darcy flow and to the effective slip for viscoplastic flow over textured surfaces.

Impact of obstructive sleep apnoea and experiences of using positive airway pressure
Creators: name: Brown, Amy
Publisher: name: Lancaster University
Year: 2020

description: The aim of this thesis was to explore the impact of the common sleep-related breathing disorder, obstructive sleep apnoea (OSA); specifically for people with a bipolar disorder (BD) diagnosis but also the wider experience of the first-line treatment for OSA, positive airway pressure (PAP). Chapter 1 is a systematic literature review and thematic synthesis of experiences using PAP to treat OSA. Twenty-five papers were reviewed and included in the thematic synthesis. The quality of each paper was appraised and considered in relation to contribution to the resultant analytical themes. The metasynthesis gave voice to user experiences of PAP and revealed barriers to PAP use at a healthcare service level. The findings highlight the need for a biopsychosocial approach and long-term person-centred support to enhance PAP use. Chapter 2 is a primary empirical research paper on an investigation as to whether people with suspected-OSA and a BD diagnosis experience more sleep and affect instability when “inter-episode” compared to people with a BD diagnosis alone. Ecological momentary assessment was utilised. Eighteen participants (twelve with suspected-OSA) wore an acitgraph for two weeks whilst completing an affect questionnaire twice daily. Measures of instability were calculated using the mean squared successive difference and probability of acute change indices. The groups were not found to significantly differ other than reduced sleep efficiency in the suspected-OSA group. However, only 48% of the intended sample was successfully recruited due to the COVID-19 pandemic. Important avenues for further research are highlighted. Chapter 3 is a critical appraisal of the thesis. Salient issues relevant to future research and clinical practice are discussed, in addition to the under recognised clinical issue of sleep which inspired this thesis.
Fuzzy Categories

Subjects: subject: Logic in Computer Science (cs.LO)

description: Since categories are graphs with additional "structure", one should start from fuzzy graphs in order to define a theory of fuzzy categories. Thus is makes sense to introduce categories whose morphisms are associated with a plausibility degree that determines to what extend it is possible to "go" from one object to another one. These categories are called {\em fuzzy categories}. Of course, the basic properties of these categories are similar but not identical to their ordinary counterparts. Thus, it is necessary to introduce notion like fuzzy commutative diagrams, fuzzy initial and fuzzy terminal objects, etc.
