description: We consider the interaction of hydrogen-like atoms with a strong laser field and show that the strong field approximation and all its variants may be grouped into a set of families of approximation schemes. This is done by introducing an ansatz describing the electron wave packet as the sum of the initial state wave function times a phase factor and a function which is the perturbative solution in the Coulomb potential of an inhomogeneous time-dependent Schrödinger equation. It is the phase factor that characterizes a given family. In each of these families, the velocity and length gauge version of the approximation scheme lead to the same results at each order in the Coulomb potential. By contrast, irrespective of the gauge, approximation schemes belonging to different families give different results. Furthermore, this new formulation of the strong field approximations allows us to gain deeper insight into the validity of the strong field approximation schemes. In particular, we address two important questions: the role of the Coulomb potential in the output channel and the convergence of the perturbative series in the Coulomb potential. In all the physical situations we consider here, our results are compared to those obtained by solving numerically the time-dependent Schrödinger equation.

description: The variational quantum eigensolver is one of the most promising algorithms for near-term quantum computers. It has the potential to solve quantum chemistry problems involving strongly correlated electrons, which are otherwise difficult to solve on classical computers. The variational eigenstate is constructed from a number of factorized unitary coupled-cluster terms applied onto an initial (single-reference) state. Current algorithms for applying one of these operators to a quantum state require a number of operations that scales exponentially with the rank of the operator. We exploit a hidden SU($2$) symmetry to allow us to employ the linear combination of unitaries approach, Our \textsc{Prepare} subroutine uses $n+2$ ancilla qubits for a rank-$n$ operator. Our \textsc{Select}($\hat U$) scheme uses $\mathcal{O}(n)$ \textsc{Cnot} gates. This results in an full algorithm that scales like the cube of the rank of the operator $n^3$, a significant reduction in complexity for rank five or higher operators. This approach, when combined with other algorithms for lower-rank operators (when compared to the standard implementation, will make the factorized form of the unitary coupled-cluster approach much more efficient to implement on all types of quantum computers.
title: Diverging interpretation of personal liberty and security: inconsistencies between the jurisprudence of the UN Human Rights Committee and the European Court of Human Rights

description: Die Menschenrechte werden durch mehrere Verträge und von mehreren Akteuren innerhalb eines vielschichtigen Systems geschützt. Dies kann zu Unstimmigkeiten darüber führen, wie die universellen Rechte zu verstehen und umzusetzen sind. Der internationale Pakt über bürgerliche und politische Rechte, die europäische Menschenrechtskonvention und zwei zentrale Menschenrechtsverträge garantieren das Recht auf Freiheit und Sicherheit in ähnlichen Formulierungen. Ihre Kontrollorgane, der UN-Menschenrechtsausschuss und der europäische Gerichtshof für Menschenrechte, legen dieses Recht jedoch teilweise unterschiedlich aus und stellen unterschiedliche Anforderungen. In dieser Arbeit wird die Rechtsprechung dieser beiden Organe zum Recht auf Freiheit und Sicherheit im Hinblick auf ihre strukturellen Merkmale und ihre Funktionsweise verglichen. Sie erörtert die festgestellten Unstimmigkeiten und die Gründe dafür im Zusammenhang mit der Funktion des vielschichtigen Schutzsystems. Es wird aufgezeigt, welche Schlüsselrolle die Beziehung zwischen diesen beiden Organen, wenn es darum geht, sicherzustellen, dass der Einzelne einen wirksamen Schutz der universellen Standards des Rechts auf Freiheit und Sicherheit genießen kann.
description: Human rights are protected under multiple treaties and by multiple actors within a multi-layered system. This may lead to inconsistencies in how universal rights are understood and implemented. The International Covenant on Civil and Political Rights and the European Convention on Human Rights, two core human rights treaties, guarantee the right to liberty and security in similar wordings. However, their supervisory bodies, the UN Human Rights Committee and the European Court of Human Rights, diverge to some extent in its interpretation and requirements. The thesis compares these two bodies' jurisprudence on the right to liberty and security, in light of their structural characteristics and functions. It discusses the identified inconsistencies and the reasons behind them within the context of the function of the multi-layered protection system. It demonstrates the key role of the relationship between these two bodies in ensuring that individuals can enjoy effective protection of the universal standards of the right to liberty and security.
Twisted supergravity, and family Donaldson invariants
Creators: name: Cushing, Jay
Publisher: name: No Publisher Supplied
Year: 2022

description: At its heart, this dissertation investigates the relationship between two of physics’ most important symmetries, diffeomorphisms and gauge transformations. Directed by the study of the metric dependence of solutions to the instanton equation of Yang-Mills theory on a smooth four manifold X, we construct a model of equivariant cohomology of the space of gauge connections A and metrics Met(X) with respect to the semi-direct product of gauge transformations G and diffeomorphisms Diff₊(X). Generalizing topologically twisted N = 2 super Yang Mills theory, we use our model to present a new set of transformation laws and action which allow for the construction of new diffeomorphism invariants of X associated to families of metrics. These are, conjecturally, the fabled family Donaldson invariants. Surprisingly, we also identify our model as a subsector of N = 2 twisted supergravity on a background with only certain components of the gravitino activated. In addition, we provide perspective on future directions for these developments.

description: We have investigated spin-electricity conversion on surface states of bulk-insulating topological insulator (TI) materials using a spin pumping technique. The sample structure is Ni-Fe|Cu|TI trilayers, in which magnetic proximity effects on the TI surfaces are negligibly small owing to the inserted Cu layer. Voltage signals produced by the spin-electricity conversion are clearly observed, and enhanced with decreasing temperature in line with the dominated surface transport at lower temperatures. The efficiency of the spin-electricity conversion is greater for TI samples with higher resistivity of bulk states and longer mean free path of surface states, consistent with the surface spin-electricity conversion.

description: The field of hardness of approximation has seen a lot of progress in the past three decades resulting in almost optimal inapproximability results for many computational problems, including all Constraint Satisfaction Problems(CSPs). However, our understanding of inapproximability is still rather limited for some fundamental problems such as approximate graph coloring, and problems for which approximation algorithms have been widely studied, for example, clustering, packing, and scheduling problems. In this thesis, we make progress on these questions by studying Promise CSPs that generalize CSPs, and more abstractly, computational problems with a given promise, either a solution satisfying a strong property, or a structural guarantee on the underlying instance. Promise Constraint Satisfaction Problems (PCSPs) generalize the traditional CSPs by allowing for a weaker and stronger form for each predicate. PCSPs have received a lot of attention recently, both on the algorithmic and hardness front, and their study has led to breakthroughs in approximate graph and hypergraph coloring problems. In this thesis, we continue that line of work, obtaining new characterization of polynomial time solvability for several classes of Promise CSPs including Boolean monotone PCSPs, variants of graph and hypergraph colorings. We also study robust algorithms for Promise CSPs, and give a dichotomy result characterizing when certain classes of PCSPs have robust algorithms. More generally, we study combinatorial problems under a given structural promise – for example, set cover on set systems where every pair of sets intersect in at most one element. We use inapproximability results on such structured instances to resolve the approximability of multidimensional packing problems and scheduling with communication delays.

description: Kaum eine Branche wurde so hart und nachhaltig von den Covid-19 bedingten Maßnahmen, Auflagen und Lockdowns getroffen, wie jene der Tourismus und Freizeitwirtschaft. Während der Pandemie befanden sich die österreichischen Tourismusorganisationen in einem stetigen Zustand des Krisenmanagement und der damit einhergehenden Krisenkommunikation, um weiterhin auf dem hart umkämpften touristischen Markt bestehen zu können und deren Stakeholder bestmöglich zu unterstützen. Im Zuge dieser Masterarbeit sollen die unterschiedlichen Maßnahmen und Herangehensweisen der Krisenkommunikation von Tourismusorganisationen, mithilfe von leitfadengestützten ExpertInneninterviews analysiert werden. Dabei werden ExpertInnen aus montanen und urbanen Tourismusregionen Österreichs interviewt und deren spezifische Wahrnehmungen und Meinungen dargelegt. Ein Vergleich zwischen den montanen und urbanen Organisationen zeigt dabei die Gemeinsamkeiten und Unterschiede in der jeweiligen Krisenkommunikation und deren umgesetzten Maßnahmen auf. Weiters werden die verwendeten Kommunikationskanäle, Rückgewinnungsmaßnahmen und die Sichtweisen der ExpertInnen, auf die Zukunft der Krisenkommunikation im Tourismus, behandelt und aufgezeigt.
description: Hardly any other sector was hit as hard and lastingly by the Covid 19-related measures, requirements and lockdowns as the tourism and leisure industry. During the pandemic, the Austrian tourism organisations were in a constant state of crisis management and the associated crisis communication in order to be able to continue to exist in the highly competitive tourism market and to support their stakeholders in the best possible way. In the course of this master’s thesis, the different measures and approaches of crisis communication of tourism organisations will be analysed with the help of guideline-based expert interviews. Experts from mountainous and urban tourism regions in Austria will be interviewed and their specific perceptions and opinions will be presented. A comparison between the mountain and urban organisations shows the similarities and differences in the respective crisis communication and the measures implemented. Furthermore, the communication channels used, recovery measures and the experts' views on the future of crisis communication in tourism are discussed and presented.

description: Recent progress in treating the dynamically screened nature of the Coulomb interaction in strongly correlated lattice models and materials is reviewed with a focus on computational schemes based on the dynamical mean field approximation. We discuss approximate and exact methods for the solution of impurity models with retarded interactions, and explain how these models appear as auxiliary problems in various extensions of the dynamical mean field formalism. The current state of the field is illustrated with results from recent applications of these schemes to U-V Hubbard models and correlated materials.

description: A test experiment to polarize tritium nuclei to develop a polarized deuterium-tritium (D-T) laser fusion concept is proposed in which a ferromagnetic complex with a high internal magnetic field is used to polarize tritium nuclei on physisorbed D-T molecules with an internal β-decay heat load in a D-T target. Heteronuclear hydrogen deuteride (HD) is used to conduct the measurements herein instead of as in typical D-T–based experiments. As proof-of-concept experimentation, the adsorption and desorption characteristics of HD are examined on Prussian blue ferromagnetic analogue Ni3[Fe(CN)6]2 at temperatures of 77 K and around 23 K. Nuclear magnetic resonance (NMR) analysis of the ferromagnetic complex-mediated adsorption of HD onto activated carbon pellets at 10 K is conducted step by step using a multilocular probe cell that had been simplified to give a single-tube probe cell. The resulting 1H NMR spectra are compared with 19F NMR spectra obtained for reference on a Kel-F probe cell wall. Slight differences between the calculated NMR frequency from the gyromagnetic ratio and the actually observed NMR frequency are also discussed.

description: We introduce self-divisible ultrafilters, which we prove to be precisely those $w$ such that the weak congruence relation $\equiv_w$ introduced by Šobot is an equivalence relation on $β\mathbb{Z}$. We provide several examples and additional characterisations; notably we show that $w$ is self-divisible if and only if $\equiv_w$ coincides with the strong congruence relation $\equiv^{\mathrm{s}}_{w}$, if and only if the quotient $(β\mathbb{Z},\oplus)/\mathord{\equiv^{\mathrm{s}}_w}$ is a profinite group. We also construct an ultrafilter $w$ such that $\equiv_w$ fails to be symmetric, and describe the interaction between the aforementioned quotient and the profinite completion $\hat{\mathbb{Z}}$ of the integers.

An evaluation of air flow measurement opportunities in industrial compressed air systems
Creators: name: Kungumaraj, Subhash
Publisher: name: No Publisher Supplied
Year: 2022

description: Compressed air system can account for a large portion of a manufacturing plant’s energy use. Therefore, efficiently operating compressed air systems can help significantly reduce energy use and cost. Compressed air usage can be measured to help maintain it properly. Historically, manufacturer’s compressor performance curves were used to calculate the mass flow rate and they were not measured directly. This was influenced by the unreliability of flow metering technology. Flow meters commonly induce pressure drops or other adverse effects on the system. They can also be intrusive to install on existing compressed air piping. Thermal mass flow meters working on the principle of heat transfer are becoming more common due to their minimal impact and non-intrusive nature. Therefore, flow rate measurement should be revisited with recent advances in flow metering technology.The goals of this thesis are to study the role of flow meters in industrial compressed air systems and develop a facility for mass flow meter evaluation. Flow meter placement was studied with respect to different system layouts. Ideal placement was determined based on type of layout and location of equipment. This also enabled baselining performance and helping maintain overall system operation. Flowmeters downstream of every compressor gives individual and total compressed air generation. On the demand side, a multiple loop and trunk layout with only one compressed air line from the main loop is a good layout design for flowmeter placement and compressed air delivery.A facility was designed and developed to evaluate mass flow meters using choked flow conditions. This enables testing of the mass flow meters at constant mass flow rates while varying the pressure. The facility also can change the choked area to evaluate mass flow meters under different mass flow rates for the same pressure ratio. A thermal mass flow meter is tested with the facility to evaluate its performance due to its recent rise in popularity. It was determined the CDI meters, CDI-5200 mass flow meter, to be accurate at high back pressure and have an error of 10% for lower back pressure. In conversation with the manufacturer, it was mentioned the flowmeter was calibrated for the higher back pressure ranges where the testing showed the flow readings matching with the pitot tube.

description: In order to exploit the intriguing optical properties of graphene it is essential to gain a better understanding of the light-matter interaction in the material on ultrashort timescales. Exciting the Dirac fermions with intense ultrafast laser pulses triggers a series of processes involving interactions between electrons, phonons and impurities. Here we study these interactions in epitaxial graphene supported on silicon carbide (semiconducting) and iridium (metallic) substrates using ultrafast time- and angle-resolved photoemission spectroscopy (TR-ARPES) based on high harmonic generation. For the semiconducting substrate we reveal a complex hot carrier dynamics that manifests itself in an elevated electronic temperature and an increase in linewidth of the $π$ band. By analyzing these effects we are able to disentangle electron relaxation channels in graphene. On the metal substrate this hot carrier dynamics is found to be severely perturbed by the presence of the metal, and we find that the electronic system is much harder to heat up than on the semiconductor due to screening of the laser field by the metal.

Partiendo de una evaluación diagnóstica que evidencia el poco conocimiento previo sobre normas y señales de tránsito que tienen los estudiantes de la institución educativa, se diseña el Recurso Educativo Digital (RED) mediante un escape room que lleva al estudiante a través de diferentes escenarios que incluyen actividades de aprendizaje y evaluaciones formativas para conocer sobre la normatividad vigente en movilidad segura. Como parte de esta investigación, se divide el grado sexto B en dos grupos, uno que es el grupo experimental a quien se le aplica el RED y otro llamado grupo de control, cuyos integrantes reciben clases tradicionales sobre el tema. Al finalizar se realiza una evaluación sumativa a ambos grupos y mediante el cálculo de la desviación estándar se comparan los resultados obtenidos, siendo evidente que el uso del RED genera motivación en los estudiantes y contribuye a favorecer la apropiación de los conocimientos en comparación a los resultados obtenidos en el grupo de control.

Computational model for cardiac electrical disease
Creators: name: Sadowski, Nicole M.
Publisher: name: No Publisher Supplied
Year: 2022

description: The sinoatrial (SA) node, located in the right atrium wall, is the heart's biological pacemaker and determines heart rate due to the generation of repetitive and spontaneous action potentials for rhythmic contractions of pacemaker cells. This rhythm is conducted via the atrioventricular (AV) node of cardiac cells in the myocardium. The funny current (If) and sinoatrial node (SAN), combined with regulation by the sympathetic and parasympathetic nervous systems, modulate the frequency of SAN-generated action potentials. Abnormalities in this system can result in cardiac arrhythmias, including partial block, complete block, tachycardia, bradycardia, and cardiac arrest. Additionally, sinus rhythm, another variety of arrhythmia, is considered normal and is defined as heart rate variability (HRV). HRV is of current interest in cardiology due to its possible value as a diagnostic indicator of the cardiac system. Notably, the dynamic beat-to-beat changes in the heart rate often precede the more fatal rhythms of tachycardia and fibrillation. Noble has developed a cellular model for a single cardiac pacemaker cell. While the Noble model successfully modeled pacemaker activity, it does not exhibit HRV or any arrhythmia by itself. Further research suggests that HRV arises from parasympathetic and sympathetic neural action on the SA pacemaker, although this concept does not explain the different varieties of arrhythmia. Currently, a single model that generally represents an array of known arrhythmia does not exist. The ideas proposed in this thesis convey multiple pacemaker cell interactions that may explain many known arrhythmias. To achieve this, this thesis studies the problem of arrhythmia by developing a computational model of dual Noble pacemaker cells that are capable of interacting with one another. All computations resulted in a MATLAB model of cell-to-cell pacemaker interaction, in which cellular parameters were adjusted to reveal the various block arrhythmias and HRV. Comparisons with natural human data pertaining to HRV were related to the standard mean R-R value measured from the generated model data. Furthermore, Fourier spectrum analysis of HRV and heart rate dynamics were presented in the form of delay plots and depicted in a bifurcation plot. The results obtained through this thesis, including results for both HRV and various types of arrhythmia, were compared to the effects of previous works and validated. It was concluded that a dual auto-arrhythmic cell interaction model could model all fatal cardiac arrhythmias and HRV. In particular, the cell-to-cell coupling was valuable in creating the various rhythms. The model developed in this thesis can be useful in providing more detailed diagnostic information of human cardiac rhythm data at the cellular level.

title: Exploring synergies in the United Nations: a focus on anti-corruption and human rights
Creators: name: Pasteknik, Betina Andrea
Year: 2023

description: In dieser Arbeit wird die Wechselwirkung zwischen Menschenrechten und Korruption untersucht, wobei die Notwendigkeit eines umfassenden Ansatzes zur gleichzeitigen Behandlung beider Themen betont wird. Es werden Synergien innerhalb des Systems der Vereinten Nationen untersucht, um Lücken zu schließen und die Zusammenarbeit zwischen den verschiedenen Einrichtungen zu fördern. Obwohl die Vereinten Nationen Dokumente formuliert haben, in denen sie die Bedeutung eines umfassenden Ansatzes zur Bewältigung der Verflechtungen zwischen Korruption und Menschenrechten hervorheben, scheint die praktische Umsetzung dieser Grundsätze ins Hintertreffen zu geraten. Durch das Aufbrechen von Silos und die Förderung der Zusammenarbeit soll die Forschung dazu beitragen, die Wirkung der Vereinten Nationen bei der Förderung von guter Regierungsführung, Transparenz und Rechenschaftspflicht zu verstärken und gleichzeitig die Menschenrechte zu schützen. Zu den Methoden gehören die Analyse der Empfehlungen der Allgemeinen Regelmäßigen Überprüfung zu Fragen der Korruptionsbekämpfung und die Nutzung von Erkenntnissen aus der Literatur und Erfahrungen aus erster Hand. Die Ergebnisse zeigen bestehende Grenzen, mögliche Verbesserungen und die zentrale Rolle der Zivilgesellschaft bei der Förderung eines ganzheitlichen Ansatzes zur Bewältigung komplexer globaler Herausforderungen auf.
description: This thesis examines the interplay between human rights and corruption, emphasizing the need for a comprehensive approach to address both issues simultaneously. It explores synergies within the United Nations system, aiming to bridge gaps and promote collaboration between different entities. Although the United Nations has formulated documents highlighting the importance of embracing a comprehensive approach to tackle the interlinkages between corruption and human rights, the practical implementation of these principles seems to be falling behind. By breaking silos and fostering collaboration, the research aims to contribute to enhancing the UN's impact in promoting good governance, transparency, and accountability while safeguarding human rights. The methods involve analyzing Universal Periodic Review recommendations on anti-corruption issues and leveraging insights from literature and first-hand experience. The outcomes highlight existing limitations, potential improvements, and the pivotal role of civil society in advocating for a holistic approach to tackling complex global challenges.

description: Accurate spine segmentation allows for improved identification and quantitative characterization of abnormalities of the vertebra, such as vertebral fractures. However, in existing automated vertebra segmentation methods on computed tomography (CT) images, leakage into nearby bones such as ribs occurs due to the close proximity of these visibly intense structures in a 3D CT volume. To reduce this error, we propose the use of joint vertebra-rib atlases to improve the segmentation of vertebrae via multi-atlas joint label fusion. Segmentation was performed and evaluated on CTs containing 106 thoracic and lumbar vertebrae from 10 pathological and traumatic spine patients on an individual vertebra level basis. Vertebra atlases produced errors where the segmentation leaked into the ribs. The use of joint vertebra-rib atlases produced a statistically significant increase in the Dice coefficient from 92.5 $\pm$ 3.1% to 93.8 $\pm$ 2.1% for the left and right transverse processes and a decrease in the mean and max surface distance from 0.75 $\pm$ 0.60mm and 8.63 $\pm$ 4.44mm to 0.30 $\pm$ 0.27mm and 3.65 $\pm$ 2.87mm, respectively.

All-optical switching in granular ferromagnets caused by magnetic circular dichroism

description: Magnetic recording using circularly polarized femto-second laser pulses is an emerging technology that would allow write speeds much faster than existing field driven methods. However, the mechanism that drives the magnetization switching in ferromagnets is unclear. Recent theories suggest that the interaction of the light with the magnetized media induces an opto-magnetic field within the media, known as the inverse Faraday effect. Here we show that an alternative mechanism, driven by thermal excitation over the anisotropy energy barrier and a difference in the energy absorption depending on polarization, can create a net magnetization over a series of laser pulses in an ensemble of single domain grains. Only a small difference in the absorption is required to reach magnetization levels observed experimentally and the model does not preclude the role of the inverse Faraday effect but removes the necessity that the opto-magnetic field is 10s of Tesla in strength.

Neural Network Analytic Continuation for Monte Carlo: Improvement by Statistical Errors

description: This study explores the use of neural network-based analytic continuation to extract spectra from Monte Carlo data. We apply this technique to both synthetic and Monte Carlo-generated data. The training sets for neural networks are carefully synthesized without ``data leakage". We found that the training set should match the input correlation functions in terms of statistical error properties, such as noise level, noise dependence on imaginary time, and imaginary time-displaced correlations. We have developed a systematic method to synthesize such training datasets. Our improved algorithm outperform the widely used maximum entropy method in highly noisy situations. As an example, our method successfully extracted the dynamic structure factor of the spin-1/2 Heisenberg chain from quantum Monte Carlo simulations.

description: This paper introduces a generalization of the empirical interpolation method (EIM) and the reduced basis method (RBM) in order to allow their combination with data mining and data assimilation. The purpose is to be able to derive sound information from data and reconstruct information, possibly taking into account noise in the acquisition, that can serve as an input to models expressed by partial differential equations. The approach combines data acquisition (with noise) with domain decomposition techniques and reduced basis approximations.

description: Recently, the negatively charged silicon vacancy centre (SiV) in diamond has emerged as a novel promising system for quantum information processing (QIP) due to its superior spectral properties and advantageous electronic structure: The SiV offers an optically accessible Λ-type level structure with a large orbital level splitting even without the need of an external magnetic field and previous studies determined the ground state coherence time of the centre to be on the order of 35-45ns. While these studies already indicate the feasibility of an ultrafast all-optical coherent control of the SiV, no experimental realization has been presented so far. Here, we report on optical Rabi oscillations and Ramsey interference between the ground and the excited state of the SiV using 12 ps long, resonant rotation pulses. Moreover, utilizing a Λ-scheme, we demonstrate Raman-based coherent Rabi rotations and Ramsey interference within the ground state manifold using a single, 1ps long off-resonant pulse. These measurements prove the accessibility of the complete set of single-qubit operations relying solely on optical fields and pave the way for high-speed QIP applications using SiV centres.

Invertibility of the retarded response functions for initial mixed states: application to one-body reduced density matrix functional theory

description: In [J. Chem. Phys. 143, 054102 (2015)] I have derived conditions to characterize the kernel of the retarded response function, under the assumption that the initial state is a ground state. In this article I demonstrate its generalization to mixed states (ensembles). To make the proof work, the weights in the ensemble need to be decreasing for increasing energies of the pure states from which the mixed state is constructed. The resulting conditions are not easy to verify, but under the additional assumptions that the ensemble weights are directly related to the energies and that the full spectrum of the Hamiltonian participates in the ensemble, it is shown that potentials only belong to the kernel of the retarded response function if they commute with the initial Hamiltonian. These additional assumptions are valid for thermodynamic ensembles, which makes this result also physically relevant. The conditions on the potentials for the thermodynamic ensembles are much stronger than in the pure state (zero temperature) case, leading to a much less involved kernel when the conditions are applied to the retarded one-body reduced density matrix response function.
