description: Constructing a Pseudo Random Function (PRF) is a fundamental problem in cryptology. Such a construction, implemented by truncating the last $m$ bits of permutations of $\{0, 1\}^{n}$ was suggested by Hall et al. (1998). They conjectured that the distinguishing advantage of an adversary with $q$ queries, ${\bf Adv}_{n, m} (q)$, is small if $q = o (2^{(n+m)/2})$, established an upper bound on ${\bf Adv}_{n, m} (q)$ that confirms the conjecture for $m < n/7$, and also declared a general lower bound ${\bf Adv}_{n,m}(q)=Ω(q^2/2^{n+m})$. The conjecture was essentially confirmed by Bellare and Impagliazzo (1999). Nevertheless, the problem of {\em estimating} ${\bf Adv}_{n, m} (q)$ remained open. Combining the trivial bound $1$, the birthday bound, and a result of Stam (1978) leads to the upper bound \begin{equation*} {\bf Adv}_{n,m}(q) = O\left(\min\left\{\frac{q(q-1)}{2^n},\,\frac{q}{2^{\frac{n+m}{2}}},\,1\right\}\right). \end{equation*} In this paper we show that this upper bound is tight for every $0\leq m

description: Growth factors (GFs) and cytokines have a great potential in regenerative medicine. However, clinical translation of these biologics has been modest. The main challenges include side effects and cost-efficiency issues which are related to the high doses required to reach therapeutic benefits. Therefore, to overcome these drawbacks, better delivery strategies need to be developed. A promising strategy is to engineer biologics to bind extracellular matrix (ECM) components. Here, we engineered platelet-derived growth factor-BB and interleukin-1 (IL-1) receptor antagonist to have a super-affinity for the ECM. Moreover, we explored the impact of IL-1 signalling on GF regenerative effects in mouse models.

description: With increasing global and ocean temperatures, the dissociation of methane hydrates at the feather edge of the of the gas hydrate stability zone (GHSZ) has become a greater concern to the scientific community. Possible responses to hydrate dissociation including seafloor methane venting and slope failure have been associated with gas generation and hydrate dissociation and have been used to create predictive maps of hydrate and gas locations around the world. Recently there has been a more concerted effort to model seafloor characteristics using machine learning methods to better estimate the global location of hydrate and gas formation. Seafloor total organic carbon (TOC) can be used to predict where methane hydrate and gas are likely to occur beneath the seafloor. I used a k-nearest neighbor machine learning model to predict global TOC at the seafloor. Within the region around the U.S. Atlantic margin (29°N–45°N and 82°W–66°W), I focused specifically on an area with high TOC predictions along the continental slope from (35.4°N, 75.0°W) to (39.0°N, 72.0°W). My research aims to model the geomechanical response of sediments to hydrate dissociation caused by increasing seafloor temperatures, specifically focused on areas along the upper continental slope. At nine locations – five hydrate bearing locations along the feather edge of the hydrate stability zone, one gas location up-dip of the feather edge, and three hydrate bearing locations down-dip of the feather edge – I modeled hydrate and gas formation due to burial over a 120,000 year time period. At each of these locations, hydrate and gas formation were modeled by sampling TOC, sedimentation rate, and heat flux. At the five locations along the feather edge, I modeled hydrate dissociation at the base of the hydrate stability zone (BHZ) due to an increase in temperature. I found that in a purely drained loading environment, no failure is expected to occur due to hydrate dissociation. However, in an undrained loading environment, shear failure is expected to occur during the hydrate dissociation process, even at low hydrate saturations (0.1% – 0.3%).

description: We study the real loci of toric degenerations of complex varieties with reducible central fibre. We show that the topology of such degenerations can be explicitly described via the Kato-Nakayama space of the central fibre as a log space. We furthermore provide generalities of real structures in log geometry and their lift to Kato-Nakayama spaces. A key point of this paper is a description of the Kato-Nakayama space of a toric degeneration and its real locus, both as bundles determined by combinatorial data. We provide several examples including real toric degenerations of K3-surfaces and a toric degeneration of local $\textbb{P}^2$.

description: We apply a novel optimization scheme from the image processing and machine learning areas, a fast Primal-Dual method, to achieve controllable and realistic fluid simulations. While our method is generally applicable to many problems in fluid simulations, we focus on the two topics of fluid guiding and separating solid-wall boundary conditions. Each problem is posed as an optimization problem and solved using our method, which contains acceleration schemes tailored to each problem. In fluid guiding, we are interested in partially guiding fluid motion to exert control while preserving fluid characteristics. With our method, we achieve explicit control over both large-scale motions and small-scale details which is valuable for many applications, such as level-of-detail adjustment (after running the coarse simulation), spatially varying guiding strength, domain modification, and resimulation with different fluid parameters. For the separating solid-wall boundary conditions problem, our method effectively eliminates unrealistic artifacts of fluid crawling up solid walls and sticking to ceilings, requiring few changes to existing implementations. We demonstrate the fast convergence of our Primal-Dual method with a variety of test cases for both model problems.

description: В последние десятилетия наблюдается рост абсолютного числа пациентов с ХСН. Данное явление связывают с увеличением доли пожилого населения. По результатам отдельных исследований распространенность ХСН пропорционально увеличивается с возрастом. Высокая распространённость гериатрических синдромов среди пожилых пациентов с ХСН, повышает актуальность применения гериатрического подхода. Цель: изучить возможности сочетания гериатрического и терапевтического подходов Материалы и методы: в исследовании приняли участие 421 пациент в возрасте 65-84 года с ХСН I-IV функционального класса (ФК). Для исследования гериатрических синдромов была проведена комплексная гериатрическая оценка (КГО) с использованием компьютерной программы «Специализированный гериатрический осмотр». 57 больным дополнительно была выполнена оценка интенсивности болевого синдрома при помощи визуальной аналоговой шкалы (ВАШ). Результаты: были выявлены достоверные различия по коэффициентам распространенности следующих синдромов: делирий (ХСН I-II ФК: 1,4±0,1 на 100 человек; ХСН III-IV ФК: 6,1±0,7 на 100 человек), синдром мальнутриции (ХСН I-II ФК: 6,3±0,9 на 100 человек; ХСН III-IV ФК: 37,5±2,2 на 100 человек), синдром когнитивных нарушений (ХСН I-II ФК: 47,3±4,4 на 100 человек; ХСН III-IV ФК: 68,2±3,9 на 100 человек), обстипационный синдром (ХСН I-II ФК: 5,8±2,4 на 100 человек; ХСН III-IV ФК: 18,9±2,1 на 100 человек), синдром падений (ХСН I-II ФК: 5,0±1,1 на 100 человек; ХСН III-IV: 57,2±6,3 на 100 человек), саркопения (ХСН I-II ФК: 4,2±0,3 на 100 человек; ХСН III-IV: 39,2±4,1 на 100 человек), тревожно-депрессивный синдром (ХСН I-II ФК: 17,2±4,4 на 100 человек; ХСН III-IV: 39,5±5,1 на 100 человек), синдром нарушения сна (ХСН I-II ФК: 18,0±4,7 на 100 человек; ХСН III-IV ФК: 40,1±4,3 на 100 человек) (p<0,05 для всех). Достоверных различий в распространенности синдромов снижения зрения и слуха, головокружения, пролежней и нарушения мочеиспускания, достоверных различий между группами выявлено не было. 57 больным был проведен анализ интенсивности боли по ВАШ. Уровень боли был достоверно выше среди пациентов с ХСН III-IV ФК и составил 4,5+0,2. В группе больных с ХСН I-II ФК 2,4+0,2 соответственно (p<0,05). Заключение: впервые проведен анализ распространенности гериатрических синдромов у пожилых пациентов с ХСН в зависимости от ФК. Выявлена четкая взаимосвязь между тяжестью ХСН и распространенностью отдельных гериатрических синдромов.

description: The area coverage problem is the task of efficiently servicing a given two-dimensional surface using sensors mounted on robots such as unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs). We present a novel formulation for generating coverage routes for multiple capacity-constrained robots, where capacity can be specified in terms of battery life or flight time. Traversing the environment incurs demands on the robot resources, which have capacity limits. The central aspect of our approach is transforming the area coverage problem into a line coverage problem (i.e., coverage of linear features), and then generating routes that minimize the total cost of travel while respecting the capacity constraints. We define two modes of travel: (1) servicing and (2) deadheading, which correspond to whether a robot is performing task-specific actions or not. Our formulation allows separate and asymmetric travel costs and demands for the two modes. Furthermore, the cells computed from cell decomposition, aimed at minimizing the number of turns, are not required to be monotone polygons. We develop new procedures for cell decomposition and generation of service tracks that can handle non-monotone polygons with or without holes. We establish the efficacy of our algorithm on a ground robot dataset with 25 indoor environments and an aerial robot dataset with 300 outdoor environments. The algorithm generates solutions whose costs are 10% lower on average than state-of-the-art methods. We additionally demonstrate our algorithm in experiments with UAVs.

description: We analytically study the ground-state phase diagrams of ultracold bosons with various values of the effective magnetic quantum number $m$ in a state-dependent hexagonal optical lattice by using the generalized effective-potential Landau theory, where the site-offset energy between the two triangular sublattice A and B is tunable. Our analytical calculations of third-order corrections are in reasonably good agreement with the previous cluster Gutzwiller calculations. Furthermore, we reveal the reason why the regions of the Mott lobes $(n,n)$ in phase diagrams for $m=0.02$ are unexpectedly expanded with increasing $J/U$ in deep lattice.

description: We construct a large, redshift complete sample of distant galaxy clusters by correlating Sloan Digital Sky Survey (SDSS) Data Release 12 (DR12) redshifts with clusters identified with the red-sequence Matched-filter Probabilistic Percolation (redMaPPer) algorithm. Our spectroscopic completeness is 97% for ~ 7,000 clusters within the redMaPPer selection limit, $z \leqslant$ 0.325, so that our cluster correlation functions are much more precise than earlier work and not suppressed by photometric redshifts. We derive an accurate power-law mass-richness relation from the observed abundance with respect to the mass function from Millennium XXL (MXXL) simulation, adjusted to the Planck weighted cosmology. The number density of clusters is found to decline by 20% over the range 0.1 $< z =$ 0.24 exceeds the MXXL prediction by 20% at the $\simeq$ 2.5$σ$ level. This tension cannot be blamed on spurious, randomly located clusters as this would reduce the correlation amplitude. Full consistency between the correlation function and the abundances is achievable for the pre-Planck values of $σ_8=$ 0.9, $Ω_m=$ 0.25, and h = 0.73, matching the improved distance ladder estimate of the Hubble constant.

description: The development of precision agriculture has gradually introduced automation in the agricultural process to support and rationalize all the activities related to field management. In particular, service robotics plays a predominant role in this evolution by deploying autonomous agents able to navigate in fields while executing different tasks without the need for human intervention, such as monitoring, spraying and harvesting. In this context, global path planning is the first necessary step for every robotic mission and ensures that the navigation is performed efficiently and with complete field coverage. In this paper, we propose a learning-based approach to tackle waypoint generation for planning a navigation path for row-based crops, starting from a top-view map of the region-of-interest. We present a novel methodology for waypoint clustering based on a contrastive loss, able to project the points to a separable latent space. The proposed deep neural network can simultaneously predict the waypoint position and cluster assignment with two specialized heads in a single forward pass. The extensive experimentation on simulated and real-world images demonstrates that the proposed approach effectively solves the waypoint generation problem for both straight and curved row-based crops, overcoming the limitations of previous state-of-the-art methodologies.

description: We calculate radiative corrections to decay rates of CP-odd Higgs boson $A$ for various decay modes in the four types of two Higgs doublet models with the softly broken discrete $Z_{2}$ symmetry. The decay branching ratios are evaluated at the next-to-leading order for electroweak corrections and the next-to-next-to-leading order for QCD corrections. We comprehensively study the impact of the electroweak corrections on the decay rates and the branching ratios. We find that the radiative corrections can sizably modify the branching ratios, especially for the $A\to Zh$ decay mode in the nearly alignment scenario, where coupling constants of the SM-like Higgs boson $h$ are close to those in the standard model. We also show correlations between the branching ratios of $A$ and the scaling factor of the SM-like Higgs boson coupling including higher-order corrections. In addition, we show characteristic predictions on the decay pattern depending on the types of Yukawa interaction, by which we can discriminate the types of Yukawa interaction in future collider experiments.

description: This thesis seeks to understand how allied health conceptualise risk and incorporate considerations related to risk into their decision making. It identifies that fear of legal risk, and ?safety in the status quo? are highly influential on decision-making. Also important are establishing risk ownership, the hierarchy of fears, self-doubt and self-blame, organisational incident reviews, blame from client, family and society, the protective shield and evaluating safety and meaning. This work helps health professionals and managers to understand both how and why they may be making risk averse decisions, and how these decisions may be at odds with patient preferences.

description: This paper studies how symplectic invariants created from Hamiltonian Floer theory change under the perturbations of symplectic structures, not necessarily in the same cohomology class. These symplectic invariants include spectral invariants, boundary depth, and (partial) symplectic quasi-states. This paper can split into two parts. In the first part, we prove some energy estimations that control the shifts of symplectic action functionals. These directly imply positive conclusions on the continuity of spectral invariants and boundary depth, in some important cases including any symplectic surface $Σ_{g \geq1}$ and any closed symplectic manifold $M$ with $\dim_{\mathcal K} H^2(M; \mathcal K) = 1$. This follows by applications on some rigidity of the subsets of a symplectic manifold in terms of heaviness and superheaviness, as well as on the continuity property of some symplectic capacities. In the second part, we generalize the construction in the first part to any closed symplectic manifold. In particular, to deal with the change of Novikov rings from symplectic structure perturbations, we construct a family of variant Floer chain complexes over a common Novikov-type ring. In this set-up, we define a new family of spectral invariants called $t$-spectral invariants, and prove that they are upper semicontinuous under the symplectic structure perturbations. This implies a quasi-isometric embedding from $(\mathbb R^{\infty}, |-|_{\infty})$ to $({\widetilde {\rm Ham}}(M, ω), |-|_{\rm Hofer})$ under some dynamical assumption, imitating a result from Usher.

description: We study the properties of a refined weak coupling limit that preserves complete positivity in order to describe non-Markovian dynamics in the spin-boson model. With this tool, we show the system presents a rich and new non-Markovian phenomenology. This implies a dynamical difference between entanglement and coherence: the latter undergoes revivals whereas the former not, despite the induced dynamics being fully incoherent. In addition, the evolution presents "quasieternal" non-Markovianity, becoming non-divisible at any time period where the system evolves qualitatively. Furthermore, the method allows for an exact derivation of a master equation that accounts for a reversible energy exchange between system and environment. Specifically, this is obtained in the form of a time-dependent Lamb shift term.

title: Österreichische Kinder- und Jugendliteratur als Mittel der Propaganda in der Zeit des Nationalsozialismus
Creators: name: Posch, Jennifer
Year: 2024

description: Kinder und Jugendliche sind durch ihre Leichtgläubigkeit und den Mangel an Erfahrung am einfachsten und schnellsten zu beeinflussen. Gerade deshalb und weil sie außerdem die Zukunft eines Systems darstellen, gilt es, sie für sich zu gewinnen. Das erkannte auch Adolf Hitler, der deshalb schon die Kleinsten nach seinen Ideologien und Vorstellungen indoktrinierte. Die Nationalsozialisten betrieben ihre Propaganda dabei auf allen Ebenen. Kinder und Jugendliche sollten möglichst ganzheitlich – also in Familie, Schule und Organisationen – beeinflusst werden. Auch der Literaturbetrieb wurde nach den Vorstellungen der Nationalsozialisten gelenkt, denn diese erkannten, dass auch Bücher ein effektives Propagandamittel darstellen, da sie eine Dauer- und Tiefenwirkung haben. Die vorliegende Masterarbeit untersucht Werke der österreichischen Kinder- und Jugendliteratur auf nationalsozialistische Propaganda. Analysiert wird, inwieweit die Texte inhaltlich Antisemitismus und den Umgang mit anderen Feinden propagieren, Adolf Hitler verehren und unterstützen, militärische sowie kriegerische Elemente beinhalten, die Volksgemeinschaft propagieren und die geschlechtsspezifischen Erwartungen der Nationalsozialisten vermitteln. Des Weiteren werden sprachliche Besonderheiten und die Beeinflussung der Emotionen durch Rhetorik analysiert. Die Textanalyse hat dabei gezeigt, dass die Nationalsozialisten definitiv Literatur zur Erreichung ihrer Ziele und Pläne eingesetzt haben. Die ausgewählten Kinder- und Jugendbücher propagieren in vielerlei Hinsicht die aufgestellten Analysekriterien und sollten daher für eine ideologische Beeinflussung bei Kinder und Jugendlichen sorgen.

description: The digital transformation of our societies and in particular information and communication technologies have revolutionized how we generate, communicate, and acquire information. Collective memory as a core and unifying force in our societies has not been an exception among many societal concepts which have been revolutionized through digital transformation. In this chapter, we have distinguished between "the digitalized collective memory" and "collective memory in the digital age". In addition to discussing these two main concepts, we discuss how digital tools and trace data can open doorways into the study of collective memory that is formed inside and outside of the digital space.

description: We formulate a physics-informed compressed sensing (PICS) method for the reconstruction of velocity fields from noisy and sparse phase-contrast magnetic resonance signals. The method solves an inverse Navier-Stokes boundary value problem, which permits us to jointly reconstruct and segment the velocity field, and at the same time infer hidden quantities such as the hydrodynamic pressure and the wall shear stress. Using a Bayesian framework, we regularize the problem by introducing a priori information about the unknown parameters in the form of Gaussian random fields. This prior information is updated using the Navier-Stokes problem, an energy-based segmentation functional, and by requiring that the reconstruction is consistent with the $k$-space signals. We create an algorithm that solves this reconstruction problem, and test it for noisy and sparse $k$-space signals of the flow through a converging nozzle. We find that the method is capable of reconstructing and segmenting the velocity fields from sparsely-sampled (15% $k$-space coverage), low ($\sim$$10$) signal-to-noise ratio (SNR) signals, and that the reconstructed velocity field compares well with that derived from fully-sampled (100% $k$-space coverage) high ($>40$) SNR signals of the same flow.

description: We present data-driven simulations for gold nanostructures, and develop a model that links total energy to geometrical features of the particle, with the ultimate goal of deriving reliable edge energies of gold. Assuming that the total energy can be decomposed into contributions from the bulk, surfaces, edges, and vertices, we use machine learning for reliable multi-variant fits of the associated coefficients. The proposed method of total energy calculations using machine learning produces almost ab-initio-like accuracy with minimal computational cost. Furthermore, a clear definition and metric for edge energy is introduced for edge-energy density calculations that avoid the troublesome definition of edge length in nanostructures. Our results for edge-energy density are 0.22 eV/Å for (100)/(100) edges and 0.20 eV/Å for (111)/(111) edges. Calculated vertex energies are about 1 eV/atom. The present method can be readily extended to other metals and edge orientations as well as arbitrary nanoparticle shapes.

description: Project stakeholders always strive for a successful project; hence there is growing concern about the factors that influence project success. Although the success of a project is influenced by various factors, project scope management plays a vital role for project success or fail. This study aims to examine the challenges and Practice of Project Scope Management on IT projects in Awash Bank. This study has reviewed literature available about management of project scope. A descriptive research design is identified as the design of this study. The population of this study was 40 employees working in the implementation of IT projects in Awash Bank. The study has used a census sampling technique. Primary data have been collected using interview and questionnaire. The study examined the activities and methods used to define the scope; the challenges of the project team in management of scope, source of scope creep, and the strength and weakness of project team in scope management. The study has found out that the primary challenge of the project team in managing scope was managing scope changes. The team used different tools and techniques to define scope, like workshop and focus group discussion but there are times that different stakeholders brought change request in the middle of the project implementation to be included in the scope that will create scope creep. Error in defining scope, insufficient involvement of stakeholder and value adding change brought by stakeholders are identified as the major causes of scope creep. Strong business sense and full commitment was identified as a major strength of the team and lack of defining clear stakeholders' requirements and lack of project management knowledge was identified as the main weakness of the project team. The study gave recommendation for the improvement of scope management like; to use standard guidelines in managing scope, to give attention for scope definition by participating all stakeholders, to use additional tools and techniques and also to use proper line of communication inside the team and with stakeholders.

description: We present a quantum algorithm for simulating the dynamics of a first-quantized Hamiltonian in real space based on the truncated Taylor series algorithm. We avoid the possibility of singularities by applying various cutoffs to the system and using a high-order finite difference approximation to the kinetic energy operator. We find that our algorithm can simulate $η$ interacting particles using a number of calculations of the pairwise interactions that scales, for a fixed spatial grid spacing, as $\tilde{O}(η^2)$, versus the $\tilde{O}(η^5)$ time required by previous methods (assuming the number of orbitals is proportional to $η$), and scales super-polynomially better with the error tolerance than algorithms based on the Lie-Trotter-Suzuki product formula. Finally, we analyze discretization errors that arise from the spatial grid and show that under some circumstances these errors can remove the exponential speedups typically afforded by quantum simulation.
