description: Dark energy can modify the dynamics of dark matter if there exists a direct interaction between them. Thus a measurement of the structure growth, e.g., redshift-space distortions (RSD), can provide a powerful tool to constrain the interacting dark energy (IDE) models. For the widely studied $Q=3βHρ_{de}$ model, previous works showed that only a very small coupling ($β\sim\mathcal{O}(10^{-3})$) can survive in current RSD data. However, all these analyses had to assume $w>-1$ and $β>0$ due to the existence of the large-scale instability in the IDE scenario. In our recent work [Phys. Rev. D 90, 063005 (2014)], we successfully solved this large-scale instability problem by establishing a parametrized post-Friedmann (PPF) framework for the IDE scenario. So we, for the first time, have the ability to explore the full parameter space of the IDE models. In this work, we reexamine the observational constraints on the $Q=3βHρ_{de}$ model within the PPF framework. By using the Planck data, the baryon acoustic oscillation data, the JLA sample of supernovae, and the Hubble constant measurement, we get $β=-0.010^{+0.037}_{-0.033}$ ($1σ$). The fit result becomes $β=-0.0148^{+0.0100}_{-0.0089}$ ($1σ$) once we further incorporate the RSD data in the analysis. The error of $β$ is substantially reduced with the help of the RSD data. Compared with the previous results, our results show that a negative $β$ is favored by current observations, and a relatively larger interaction rate is permitted by current RSD data.

description: Several Machine Learning (ML) methodologies have been proposed to improve security in Internet Of Things (IoT) networks and reduce the damage caused by the action of malicious agents. However, detecting and classifying attacks with high accuracy and precision is still a major challenge. This paper proposes an online attack detection and network traffic classification system, which combines stream Machine Learning, Deep Learning, and Ensemble Learning technique. Using multiple stages of data analysis, the system can detect the presence of malicious traffic flows and classify them according to the type of attack they represent. Furthermore, we show how to implement this system both in an IoT network and from an ML point of view. The system was evaluated in three IoT network security datasets, in which it obtained accuracy and precision above 90% with a reduced false alarm rate.

description: We present constraints on the parameters of the $Λ$CDM cosmological model in the presence of massive neutrinos, using the one-dimensional Ly$α$ forest power spectrum obtained with the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey (SDSS) by Palanque-Delabrouille et al. (2013), complemented by additional cosmological probes. The interpretation of the measured Ly$α$ spectrum is done using a second-order Taylor expansion of the simulated power spectrum. BOSS Ly$α$ data alone provide better bounds than previous Ly$α$ results, but are still poorly constraining, especially for the sum of neutrino masses $\sum m_ν$, for which we obtain an upper bound of 1.1~eV (95\% CL), including systematics for both data and simulations. Ly$α$ constraints on $Λ$CDM parameters and neutrino masses are compatible with CMB bounds from the Planck collaboration. Interestingly, the combination of Ly$α$ with CMB data reduces the uncertainties significantly, due to very different directions of degeneracy in parameter space, leading to the strongest cosmological bound to date on the total neutrino mass, $\sum m_ν< 0.15$~eV at 95\% CL (with a best-fit in zero). Adding recent BAO results further tightens this constraint to $\sum m_ν< 0.14$~eV at 95\% CL. This bound is nearly independent of the statistical approach used, and of the different combinations of CMB and BAO data sets considered in this paper in addition to Ly$α$. Given the measured values of the two squared mass differences $Δm^2$, this result tends to favor the normal hierarchy scenario against the inverted hierarchy scenario for the masses of the active neutrino species.

title: Polygynie als Antwort auf die sexuelle Krise?
Creators: name: Kraus, Kerstin
Year: 2021

description: In der vorliegenden Abschlussarbeit wird eine Auswahl an Schriften des österreichischen Philosophen Christian Freiherr von Ehrenfels (1859–1932) untersucht. Ehrenfels propagierte darin eine polygyne Reform der Sexualordnung. Der Fokus dieser Arbeit liegt in der Analyse der Sexualitäts- und Geschlechterkonzeptionen, auf denen Ehrenfels‘ Schriften beruhen. Um diese herauszuarbeiten und zu interpretieren, wird auf den diskursiven Kontext der Jahrhundert-wende eingegangen und zugleich wesentliche Theorien der Sexualitäts- und Geschlechtergeschichte wiedergegeben. Die Untersuchung bringt hervor, dass die Sexualitäts- und Geschlechterentwürfe, welche der Ehrenfels’schen misogynen Zuchtutopie entspringen, tief in die Krisenstimmung des Fin-de-Siècle eingebettet sind. Sein Eintreten für die Institution der Polygamie war durchaus ungewöhnlich, seine Motivatoren waren jedoch tief in die Diskursstränge der Jahrhundertwende eingeflochten. Im zweiten Teil der Arbeit werden Ehrenfels‘ Vermittlungsstrategien herausgearbeitet. Geleitet von der These, dass das Verfechten einer polygynen Reform das „Feld des Sagbaren“ (Siegfried Jäger) überschreitet, werden jene Strategien eruiert, mithilfe derer der Autor seine Reform „sagbar“ machte. Ein abschließender Blick auf die zeitgenössische Rezeption der Schriften zeigt, dass Ehrenfels‘ Bemühungen um eine polygyne Sexualordnung kaum Zuspruch fanden – was zugleich den europäischen Polygamie-Diskurs widerspiegelt.
description: This master thesis examines a selection of writings from the Austrian philosopher Baron Christian von Ehrenfels (1859–1932) in which he introduced a sexual reform based on polygyny. This paper focuses on the central concepts of gender and sexuality in Ehrenfels’ analyses. To study and interpret these, a detailed discursive context of the turn of the century will be given. Furthermore, current theories focusing on research on sexuality and gender roles in history will be included. This academic paper shows that sexuality and gender concepts, which form the basis of Ehrenfels’ misogynous and eugenic utopia, were deeply rooted within the ideas and insecurities accompanied by the fin-de-siècle. Although his commitment for the institution of polygamy was uncommon, Ehrenfels’ writings include various contemporaneous discourses. Additionally, the “Vermittlungsstrategien” which underlie the writings of Ehrenfels will be a major part of the analysis. Guided by the assumption that a polygynous reform was something beyond the speakable (Siegfried Jäger), the author had to use various discursive strategies to express his ideas. Finally, a glance at the public reception of Ehrenfels’ articles shows that he was heard and read by his contemporaries, yet they did not approve with his advocacy for polygyny – which highlights Europe’s polygamy-discourse.

description: To conduct an in-depth study on the spatial distribution of traffic conflicts in the continuous merging areas of cross-river bridges and ensure public transportation safety. First, we utilized drone aerial photography to collect videos of vehicle movements. Using the YOLOv7 object detection algorithm and the Strong SORT multi-object tracking algorithm, we extracted high-precision vehicle trajectory time-series data. Next, based on the motion characteristics of traffic entities, we proposed using Deceleration Rate (DR) to describe rear-end conflicts and Lane Change Speed (LCS) to describe lane-changing conflicts. Additionally, we employed the K-means clustering method to determine the threshold values for minor, moderate, and severe levels of rear-end and lane-changing conflicts. Finally, based on the obtained trajectory data, the values of traffic conflicts are calculated and their severity is classified. A heat map of the spatial distribution of vehicle conflicts in continuous merging zones is then created to study the spatial distribution patterns of traffic conflicts. The threshold values for minor, moderate, and severe levels of rear-end conflicts are determined to be 3.06 m/s2, 5.36 m/s2, and 8.04 m/s2, respectively. For lane-changing conflicts, the thresholds are 1.13 m/s, 2.07 m/s, and 3.45 m/s. The spatial distribution of traffic conflicts exhibits a “first increase, then decrease, and then increase again” trend. The study identifies the critical areas of traffic conflicts in the continuous merging zones of cross-river bridges. The research results provide a novel approach for acquiring traffic data in these areas and offer a reliable quantitative method for assessing safety risks on these road segments. This provides a theoretical basis for proposing targeted traffic safety management strategies.

description: Flat/CCFT is a correspondence between gravity in asymptotically flat backgrounds and a field theory which is given by contraction of conformal field theory. In order to find a dictionary for Flat/CCFT correspondence one can start from the AdS/CFT and take the contraction of CFT in the boundary as the dual description of the flat-space limit (zero cosmological constant limit) of the asymptotically AdS spacetimes in the bulk side. In this paper we show that the Cardy-like formula of CCFT_2 is given by contraction of a proper formula in the CFT_2. This formula is the modified Cardy formula which gives the entropy of inner horizon of BTZ black holes.

description: This paper describes the design and evaluation of DSAScratch, an extension to Scratch, a widely used block-based programming language. The DSAScratch framework implements advanced data structures such as arrays, sets, dictionaries, and searching and sorting algorithms. By presenting these concepts in an intuitive block-based interface, these blocks abstract away technical details and simplify data structures and algorithms concepts for K-12 students to grasp and apply to programming problems more readily. A preliminary evaluation of the tool's usability and learning outcomes is presented in this paper. Given the information we have gathered about DSAScratch, we show that the extension is beneficial for students to develop a deeper understanding of programming and an intuitive understanding of these concepts in high school. We present the methodology and preliminary results of a user study conducted with ten high school students. During the user study, 70% of the participants understood the key ideas behind DSAScratch implemented data structures and algorithms through a mixture of lectures and hands-on activities. We show that DSAScratch was also an important part of the workshop for 90% of the students who participated, as it enhanced their understanding of algorithms and data structures. Furthermore, they indicated that they would recommend DSAScratch to their peers.

description: User experience (UX) has undergone a revolution in collaborative practices, due to tools that enable quick feedback and continuous collaboration with a varied team across a design's lifecycle. However, it is unclear how this shift in collaboration has been received in professional UX practice, and whether new pain points have arisen. To this end, we conducted a survey (N=114) with UX practitioners at software organizations based in the U.S. to better understand their collaborative practices and tools used throughout the design process. We found that while an increase in collaborative activity enhanced many aspects of UX work, some long-standing challenges -- such as handing off designs to developers -- still persist. Moreover, we observed new challenges emerging from activities enabled by collaborative tools such as design system management. Based on our findings, we discuss how UX practices can improve collaboration moving forward and provide concrete design implications for collaborative UX tools.

description: The angular distribution of the phase space arising in two-particle emission reactions induced by electrons and neutrinos is computed in the laboratory (Lab) system by boosting the isotropic distribution in the center of mass (CM) system used in Monte Carlo generators. The Lab distribution has a singularity for some angular values, coming from the Jacobian of the angular transformation between CM and Lab systems. We recover the formula we obtained in a previous calculation for the Lab angular distribution. This is in accordance with the Monte Carlo method used to generate two-particle events for neutrino scattering\cite{Sob12}. Inversely, by performing the transformation to the CM system, it can be shown that the phase-space function, which is proportional to the two particle-two hole (2p-2h) hadronic tensor for a constant current operator, can be computed analytically in the frozen nucleon approximation, if Pauli blocking is absent. The results in the CM frame confirm our previous work done using an alternative approach in the Lab frame. The possibilities of using this method to compute the hadronic tensor by a boost to the CM system are analyzed.

description: Flow-induced configuration dynamics and scission of rodlike micelles are studied for the first time using molecular dynamics simulations in presence of explicit solvent and salt. Predicted dependence of tumbling frequency and orientation distribution on shear rate S agrees with mesoscopic theories. However, micelle stretching increases the distance between the cationic head groups and adsorbed counter ions, which reduces electrostatic screening and increases the overall energy Phi linearly with micelle length. Micelle scission occurs when Phi exceeds a threshold value, independent of S.

description: Deploying Deep Learning (DL) on embedded end devices is a scorching trend in pervasive computing. Since most Microcontrollers on embedded devices have limited computing power, it is necessary to add a DL accelerator. Embedded Field Programmable Gate Arrays (FPGAs) are suitable for deploying DL accelerators for embedded devices, but developing an energy-efficient DL accelerator on an FPGA is not easy. Therefore, we propose the ElasticAI-Workflow that aims to help DL developers to create and deploy DL models as hardware accelerators on embedded FPGAs. This workflow consists of two key components: the ElasticAI-Creator and the Elastic Node. The former is a toolchain for automatically generating DL accelerators on FPGAs. The latter is a hardware platform for verifying the performance of the generated accelerators. With this combination, the performance of the accelerator can be sufficiently guaranteed. We will demonstrate the potential of our approach through a case study.

description: The hot Jupiter WASP-43b has now joined the ranks of transiting hot Jupiters HD 189733b and HD 209458b as an exoplanet with a large array of observational constraints on its atmospheric properties. Because WASP-43b receives a similar stellar flux as HD 209458b but has a rotation rate 4 times faster and a much higher gravity, studying WASP-43b serves as a test of the effect of rotation rate and gravity on the circulation when stellar irradiation is held approximately constant. Here we present 3D atmospheric circulation models of WASP-43b using the SPARC/MITgcm, a coupled radiation and circulation model, exploring the effects of composition, metallicity, and frictional drag. We find that the circulation regime of WASP-43b is not unlike other hot Jupiters, with equatorial superrotation that yields an eastward-shifted hotspot and large day-night temperature variations (~600 K at photospheric pressures). We then compare our model results to observations from Stevenson et al. which utilize HST/WFC3 to collect spectrophotometric phase curve measurements of WASP-43b from 1.12-1.65 microns. Our results show the 5x solar model lightcurve provides a good match to the data, with a phase offset of peak flux and planet/star flux ratio that is similar to observations; however, the model nightside appears to be brighter. Nevertheless, our 5x solar model provides an excellent match to the WFC3 dayside emission spectrum. This is a major success, as the result is a natural outcome of the 3D dynamics with no model tuning, and differs significantly from 1D models that can generally only match observations when appropriately tuned. In sum, these results demonstrate that 3D circulation models can provide important insights in interpreting exoplanet atmospheric observations, even at high spectral resolution, and highlight the potential for future observations with HST, JWST and other next-generation telescopes.

description: Loop ramps are complex due to their combination of horizontal curves and vertical alignments. Analyzing driving behavior and measuring safety levels can provide insights for designers, helping to improve the performance and alignment of design assumptions with actual driving behavior on loops. Therefore, the primary objective of this research is to explore the safety, performance and geometric configuration of the main body and general shape of free-flow loop ramps in the free-following mode. The study uses data from a UAV to investigate vehicle demand behavior. Maximum lateral acceleration (ay,i) in loops is used as a Surrogate Safety Measure (SSM), along with a new parameter, the a/b ratio, to determine the general shape of loop bodies. The study presents the Loop Safety Level (LSL), an approach for proactive risk analysis and ranking that relies on threshold lateral acceleration (at), 85th percentile maximum lateral acceleration (ay,max,85%), and crash analysis. A higher LSL value points to a more critical safety concern regarding the loop’s shape in relation to lateral acceleration caused by driving behaviors. Comparing crash statistics with lateral acceleration results enables the LSL to provide appropriate safety ratings and diagnose loop segment safety. A prediction model for maximum lateral acceleration, based on loop geometry, demonstrates a good fit (R2=0.88) between observed and predicted data. The study enhances understanding of safety considerations in geometric configuration and general shape enhancement of loops during the design process.

description: We continue our study of finite BRST-antiBRST transformations for general gauge theories in Lagrangian formalism, initiated in [arXiv:1405.0790[hep-th] and arXiv:1406.0179[hep-th]], with a doublet $λ_{a}$, $a=1,2$, of anticommuting Grassmann parameters and prove the correctness of the explicit Jacobian in the partition function announced in [arXiv:1406.0179[hep-th]], which corresponds to a change of variables with functionally-dependent parameters $λ_{a}=U_{a}Λ$ induced by a finite Bosonic functional $Λ(ϕ,π,λ)$ and by the anticommuting generators $U_{a}$ of BRST-antiBRST transformations in the space of fields $ϕ$ and auxiliary variables $π^{a},λ$. We obtain a Ward identity depending on the field-dependent parameters $λ_{a}$ and study the problem of gauge dependence, including the case of Yang--Mills theories. We examine a formulation with BRST-antiBRST symmetry breaking terms, additively introduced to the quantum action constructed by the Sp(2)-covariant Lagrangian rules, obtain the Ward identity and investigate the gauge-independence of the corresponding generating functional of Green's functions. A formulation with BRST symmetry breaking terms is developed. It is argued that the gauge independence of the above generating functionals is fulfilled in the BRST and BRST-antiBRST settings. These concepts are applied to the average effective action in Yang--Mills theories within the functional renormalization group approach.

title: Die Rezeption des ungarischen Holocaust 1939-1945 von der Nachkriegszeit bis zum Ende der Rákosi-Ära
Creators: name: Blume, Flavius
Year: 2021

description: Mit der Gesamtkapitulation des Dritten Reiches und dem Ende des zweiten Weltkrieges im Jahr 1945 lagen große Teile der Welt in Schutt und Asche. Doch nicht nur die kriegerischen Auseinandersetzungen und deren Verwüstungen bestimmten das Weltbild, sondern auch das Bekanntwerden der Tatsache, was es bedeutet, wenn ein ideologischer Rassekrieg geführt wird. In dieser Hinsicht ist der Holocaust 1933 – 1945 wohl der traurige Höhepunkt einer jahrhundertlangen Entwicklung, der das jüdische Leben inner- und außerhalb Europas nach wie vor bestimmt und dessen Diskurs als unabschließbar erscheint. Eines der Länder, welches auch heute noch nach wie vor in der Diskussion teils diskussionswürdige Rollen einnimmt ist Ungarn, ein Land dessen nahezu gesamte jüdische Bevölkerung binnen weniger Monate auf einen Schlag ausgelöscht wurde. Zwischen 1944 und 1945 sollten ab dem Einmarsch der Deutschen Gräueltaten verübt werden, die im Gesamtkontext von Zeit zu Zeit aus dem Blickwinkel des Betrachters verschwinden. Doch vor allem für die Entwicklung des literarischen und des Filmlebens und deren Rezeption, die bereits in den frühen Nachkriegsjahren einsetzen sollte, waren diese Ereignisse maßgeblich. Diese Arbeit widmet sich daher den literarischen und filmischen Werken, sowie ihrer Rezeption in den Jahren 1945 bis 1956, die heute stellvertretend für das ungarisch-jüdische Kulturleben stehen. Der allgemeine Aspekt der Untersuchung lautet dabei stets: Wie und inwiefern fand eine Rezeption jüdischer Film- und Literaturwerke statt? Ziel ist es, einen detaillierten Überblick über den Diskurs zu gewinnen und eine Aufarbeitung des Themas in der Hinsicht einer ungarischen Verantwortung am Holocaust im deutsch- und im ungarischsprachigen Raum einzuleiten und zu verankern.

description: We study general implications of the IceCube observations in the energy range from $10^{6}$ GeV to $10^{10}$ GeV for the origin of extragalactic ultrahigh energy cosmic rays assuming that high energy neutrinos are generated by the photomeson production of protons in the extragalactic universe. The PeV-energy neutrino flux observed by IceCube gives strong bounds on the photomeson-production optical depth of protons in their sources and the intensity of the proton component of extragalactic cosmic rays. The neutrino flux implies that extragalactic cosmic-ray sources should have the optical depth greater than $\sim 0.01$ and contribute to more than a few percent of the observed bulk of cosmic rays at 10 PeV. If the spectrum of cosmic rays from these extragalactic sources extends well beyond 1 EeV, the neutrino flux indicates that extragalactic cosmic rays are dominant in the observed total cosmic-ray flux at 1 EeV and above, favoring the dip transition model of cosmic rays. The cosmic-ray sources are also required to be efficient neutrino emitters with the optical depth close to unity in this case. The highest energy cosmic-ray ($\sim 10^{11}$ GeV) sources should not be strongly evolved with redshift to account for the IceCube observations, suggesting that any cosmic-ray radiation scenarios involving distant powerful astronomical objects with strong cosmological evolution are strongly disfavored. These considerations conclude that none of the known extragalactic astronomical objects can be simultaneously a source of both PeV and trans-EeV energy cosmic rays. We also discuss a possible effect of cosmic-ray propagation in magnetized intergalactic space to the connection between the observed total cosmic-ray flux and neutrino flux.

description: Twenty years ago, construction began on the Laser Interferometer Gravitational-wave Observatory (LIGO). Advanced LIGO, with a factor of ten better design sensitivity than Initial LIGO, will begin taking data this year, and should soon make detections a monthly occurrence. While Advanced LIGO promises to make first detections of gravitational waves from the nearby universe, an additional factor of ten increase in sensitivity would put exciting science targets within reach by providing observations of binary black hole inspirals throughout most of the history of star formation, and high signal to noise observations of nearby events. Design studies for future detectors to date rely on significant technological advances that are futuristic and risky. In this paper we propose a different direction. We resurrect the idea of a using longer arm lengths coupled with largely proven technologies. Since the major noise sources that limit gravitational wave detectors do not scale trivially with the length of the detector, we study their impact and find that 40~km arm lengths are nearly optimal, and can incorporate currently available technologies to detect gravitational wave sources at cosmological distances $(z \gtrsim 7)$.

description: Large-scale colored point clouds have many advantages in navigation or scene display. Relying on cameras and LiDARs, which are now widely used in reconstruction tasks, it is possible to obtain such colored point clouds. However, the information from these two kinds of sensors is not well fused in many existing frameworks, resulting in poor colorization results, thus resulting in inaccurate camera poses and damaged point colorization results. We propose a novel framework called Camera Pose Augmentation (CP+) to improve the camera poses and align them directly with the LiDAR-based point cloud. Initial coarse camera poses are given by LiDAR-Inertial or LiDAR-Inertial-Visual Odometry with approximate extrinsic parameters and time synchronization. The key steps to improve the alignment of the images consist of selecting a point cloud corresponding to a region of interest in each camera view, extracting reliable edge features from this point cloud, and deriving 2D-3D line correspondences which are used towards iterative minimization of the re-projection error.

description: Data-flow analyses like points-to analysis can vastly improve the precision of other analyses, and help perform powerful code optimizations. However, whole-program points-to analysis of large programs tend to be expensive - both in terms of time and memory. Consequently, many compilers (both static and JIT) and program-analysis tools tend to employ faster - but more conservative - points-to analysis to improve usability. As an alternative to such trading of precision for performance, various techniques have been proposed to perform precise yet expensive fixed-point points-to analyses ahead of time in a static analyzer, store the results, and then transmit them to independent compilation/program-analysis stages that may need them. However, an underlying concern of safety affects all such techniques - can a compiler (or program analysis tool) trust the points-to analysis results generated by another compiler/tool?
 In this work, we address this issue of trust, while keeping the issues of performance efficiency in mind. We propose ART: Analysis-results Representation Template - a novel scheme to efficiently and concisely encode results of flow-sensitive, context-insensitive points-to analysis computed by a static analyzer for use in any independent system that may benefit from such a highly precise points-to analysis. Our scheme has two components: (i) a producer that can statically perform expensive points-to analysis and encode the same concisely. (ii) a consumer that, on receiving such encoded results, can regenerate the points-to analysis results encoded by the artwork if it is deemed safe. We demonstrate the usage of ART by implementing a producer (in Soot) and two consumers (in Soot and the Eclipse OpenJ9 JIT compiler). We evaluate our implementation over various benchmarks from the DaCapo and SPECjvm2008 suites.

description: This paper proposes a paradigm of uncertainty injection for training deep learning model to solve robust optimization problems. The majority of existing studies on deep learning focus on the model learning capability, while assuming the quality and accuracy of the inputs data can be guaranteed. However, in realistic applications of deep learning for solving optimization problems, the accuracy of inputs, which are the problem parameters in this case, plays a large role. This is because, in many situations, it is often costly or sometime impossible to obtain the problem parameters accurately, and correspondingly, it is highly desirable to develop learning algorithms that can account for the uncertainties in the input and produce solutions that are robust against these uncertainties. This paper presents a novel uncertainty injection scheme for training machine learning models that are capable of implicitly accounting for the uncertainties and producing statistically robust solutions. We further identify the wireless communications as an application field where uncertainties are prevalent in problem parameters such as the channel coefficients. We show the effectiveness of the proposed training scheme in two applications: the robust power loading for multiuser multiple-input-multiple-output (MIMO) downlink transmissions; and the robust power control for device-to-device (D2D) networks.

description: 3D promises a new dimension in composing systems by aggregating chips. Literally. While the most common uses are still tightly connected with its early forms as a packaging technology, new application domains have been emerging. As the underlying technology continues to evolve, the unique leverages of 3D have become increasingly appealing to a larger range of applications: from embedded mobile applications to servers and memory systems. In this paper we focus on the system-level implications of 3D technology, trying to differentiate the unique advantages that it provides to different market segments and applications.
title: Gentechnik am Menschen
Creators: name: Koch, Andreas

description: Diese Masterarbeit setzt sich in vier Teilen mit dem Thema der Gentechnik am Menschen aus ethischer Perspektive auseinander. Im Fokus steht die Forschungsfrage, ob eine Grenzziehung in humaner Gentechnik notwendig und ethisch rechtfertigbar ist. Der erste Teil bearbeitet die biologischen und gentechnischen Grundlagen. Im zweiten Teil wird eine Verhältnisbestimmung zwischen Technik, Mensch und Gentechnik diskutiert. Im Anschluss ergibt sich daraus eine anthropologische Grundsatzdiskussion, die sich aus den ersten zwei Teilen speist. Der dritte und vierte Teil greift exemplarisch drei gentechnische Methoden in der Anwendung am Menschen auf, um an ihnen die ethische Diskussion darzustellen. Im Fokus stehen CRISPR/Cas9-Methode, Präimplantationsdiagnostik und die Forschung an Humanen Embryonalen Stammzellen. Begriffe wie Enhancement, Au-tonomie, Würde, Therapie, Gesundheit, Nutzen und Risiko werden in der Analyse der Argumentationen berücksichtigt. Die Schlussfolgerung legt nahe, dass die Forschungs-frage nicht ausreichend beantwortet werden kann.

description: We construct the bosonization of the Fock space $\mathit{F^{\otimes \frac{1}{2}}}$ of a single neutral fermion by using a 2-point local Heisenberg field. We decompose the Fock space $\mathit{F^{\otimes \frac{1}{2}}}$ as a direct sum of irreducible highest weight modules for the Heisenberg algebra $\mathcal{H}_{\mathbb{Z}}$, and thus we show that under the Heisenberg $\mathcal{H}_{\mathbb{Z}}$ action the Fock space $\mathit{F^{\otimes \frac{1}{2}}}$ of the single neutral fermion is isomorphic to the Fock space $\mathit{F^{\otimes 1}}$ of a pair of charged free fermions, thereby constructing the boson-fermion correspondence of type D-A. As a corollary we obtain the Jacobi identity equating the graded dimension formulas utilizing both the Heisenberg and the Virasoro gradings on $\mathit{F^{\otimes \frac{1}{2}}}$. We construct a family of 2-point-local Virasoro fields with central charge $-2+12λ-12λ^2, \ λ\in \mathbb{C}$, on the Fock space $\mathit{F^{\otimes \frac{1}{2}}}$. We construct a $W_{1+\infty}$ representation on $\mathit{F^{\otimes \frac{1}{2}}}$ and show that under the $W_{1+\infty}$ action $\mathit{F^{\otimes \frac{1}{2}}}$ is again isomorphic to $\mathit{F^{\otimes 1}}$.

description: The increasing adoption of distributed energy resources, particularly photovoltaic (PV) panels, has presented new and complex challenges for power network control. With the significant energy production from PV panels, voltage issues in the network have become a problem. Currently, PV smart inverters (SIs) are used to mitigate the voltage problems by controlling their active power generation and reactive power injection or absorption. However, reducing the active power output of PV panels can be perceived as unfair to some customers, discouraging future installations. To solve this issue, in this paper, a reinforcement learning technique is proposed to address voltage issues in a distribution network, while considering fairness in active power curtailment among customers. The feasibility of the proposed approach is explored through experiments, demonstrating its ability to effectively control voltage in a fair and efficient manner.

description: This paper introduces a systematic approach to address the topological path identification (TPI) problem in power distribution networks. Our approach starts by listing the DSO's raw information coming from several sources. The raw information undergoes a transformation process using a set of transformation functions. This process converts the raw information into well-defined information exploitable by an algorithm. Then a set of hypothetical paths is generated, considering any potential connections between the elements of the power distribution system. This set of hypothetical paths is processed by the algorithm that identifies the hypothetical paths that are compatible with the well-defined information. This procedure operates iteratively, adapting the set of transformation functions based on the result obtained: if the identified paths fail to meet the DSO's expectations, new data is collected, and/or the transformation functions found to be responsible for the discrepancies are modified. The systematic procedure offers practical advantages for DSOs, including improved accuracy in path identification and high adaptability to diverse network configurations, even with incomplete or inaccurate data. Consequently, it emerges as a useful tool for the construction of digital twins of power distribution networks that aligns with DSO expectations.

description: The paper presents the detailed study of controlled dense coding scheme for different types of $3$ and $4-$ particle states. It consists of GHZ state, GHZ type states, Maximal Slice state, Four particle GHZ state and W class of states. It is shown that GHZ-type states can be used for controlled dense coding in a probabilistic sense. We have shown relations among parameter of GHZ type state, concurrence of the shared bipartite state by two parties with respect to GHZ type and Charlie's measurement angle $θ$. We have seen that tripartite W state and quadripartite W state cannot be used in controlled dense coding whereas $\vert W_{n}\rangle_{ABC}$ states can be used probabilistically. Finally, we have investigated controlled dense coding scheme for tripartite qutrit states.

description: We measure the low-frequency thermal fluctuations of pure spin current in a Platinum film deposited on yttrium iron garnet via the inverse spin Hall effect (ISHE)-mediated voltage noise as a function of the angle $α$ between the magnetization and the transport direction. The results are consistent with the fluctuation dissipation theorem in terms of the recently discovered spin Hall magnetoresistance (SMR). We present a microscopic description of the $α$ dependence of the voltage noise in terms of spin current fluctuations and ISHE.

description: Graph Neural Network (GNN) models on streaming graphs entail algorithmic challenges to continuously capture its dynamic state, as well as systems challenges to optimize latency, memory, and throughput during both inference and training. We present D3-GNN, the first distributed, hybrid-parallel, streaming GNN system designed to handle real-time graph updates under online query setting. Our system addresses data management, algorithmic, and systems challenges, enabling continuous capturing of the dynamic state of the graph and updating node representations with fault-tolerance and optimal latency, load-balance, and throughput. D3-GNN utilizes streaming GNN aggregators and an unrolled, distributed computation graph architecture to handle cascading graph updates. To counteract data skew and neighborhood explosion issues, we introduce inter-layer and intra-layer windowed forward pass solutions. Experiments on large-scale graph streams demonstrate that D3-GNN achieves high efficiency and scalability. Compared to DGL, D3-GNN achieves a significant throughput improvement of about 76x for streaming workloads. The windowed enhancement further reduces running times by around 10x and message volumes by up to 15x at higher parallelism.
