description: Millimeter-wave (mmWave) radars allow for greater capabilities for material classification when compared to pre-existing models. Current models primarily utilize RGB cameras which depend solely on the appearance of an object. The mmWave radar offers higher accuracy in material detection because it relies on identifying radio frequencies rather than images. The mmWave radar can also be used in various environments - including those that are pitch-black or even filled with smoke - without compromising accuracy levels. On the other hand, the accuracy of RGB cameras is affected when used in similar conditions. This study focuses on material classification using mmWave radars in an indoor environment and it involves small-scale tests to evaluate the accuracy of mmWave radars when differentiating between four types of materials: plastic, wood, metal, and water. Our goal is to measure the intensity value of the 3D points correlating to each material and analyze how the value differs by object. We hypothesize that the intensity value will differ by material, also correlating to how much light is absorbed by each material type. We seek to use mmWave radars in conjunction with RGB cameras to improve existing models by allowing for greater accuracy in material classification under diverse environments.

description: Der voranschreitende Transformationsprozess des deutschen Energieversorgungssystems erfordert in den kommenden Jahren insbesondere in den Mittel- und Niederspannungsnetzen einen bedarfsgerechten Ausbau. Mehrere voneinander unabhängige Studien haben gezeigt, dass Smart-Grid-Technologien einen wesentlichen Beitrag zu einem möglichst kostengünstigen Ausbau dieser Netze leisten können. Zum einen ist bislang jedoch unklar, wie zuverlässig Smart-Grid-Technologien sind und zum anderen welche Auswirkungen damit auf die Zuverlässigkeit von Mittel- und Niederspannungsnetzen einhergehen. Zur Beantwortung dieser beiden Fragestellungen werden im Rahmen dieser Arbeit Smart-Grid-Technologien mithilfe von analytischen Verfahren zur Zuverlässigkeitsberechnung umfassend nachgebildet. Zudem werden die Auswirkungen dieser Technologien anhand einer Vielzahl realer Mittel- und Niederspannungsnetze verdeutlicht und zu Grundsätzen verdichtet. Des Weiteren werden die entwickelten Ansätze auf Systemautomatiken im Übertragungsnetz übertragen.

description: In this paper, we study methods to estimate drivers' posture in vehicles using acceleration data of wearable sensor and conduct a field test. Recently, sensor technologies have been progressed. Solutions of safety management to analyze vital data acquired from wearable sensor and judge work status are proposed. To prevent huge accidents, demands for safety management of bus and taxi are high. However, acceleration of vehicles is added to wearable sensor in vehicles, and there is no guarantee to estimate drivers' posture accurately. Therefore, in this paper, we study methods to estimate driving posture using acceleration data acquired from T-shirt type wearable sensor hitoe, conduct field tests and implement a sample application.

description: In der vorliegenden Masterarbeit geht es um die Vermittlung der Lernstrategien im Alphabetisierungskurs. Die TeilnehmerInnen, die einen Alphabetisierungskurs besuchen, haben geringe oder keine schriftsprachlichen Kenntnisse. Und um diese Sprachkenntnisse anzueignen, besuchen sie die Alphabetisierungskurse. Jedoch erlauben die Rahmenbedingungen von einem ÖIF (Österreichischer Integrationsfonds) geförderten Kurs nur zwei Kursantritte, die meistens für die TeilnehmerInnen nicht ausreichen. Die Vermittlung der Lernstrategien soll die TeilnehmerInnen unterstützten, ihren Lernprozess zu optimieren und zu beschleunigen. Durch Aktionsforschung wurden vier ausgewählte Lernstrategien im Unterricht vorgestellt, geübt und abschließend von den TeilnehmerInnen evaluiert. Es stellte sich heraus, dass die Vermittlung der Lernstrategien getrennt und zusammen mit dem gängigen Lernstoff im Unterricht möglich ist. Wichtig hierbei sind die Übungsphasen der Lernstrategien. Die Anwendung der vermittelten Lernstrategien sollen im Unterricht in geplanten Übungsphasen geübt werden.

It provides the right number of physical degrees of freedom and yields generalization of the Frenkel and BMT equations to the case of an arbitrary electromagnetic field. For a particle with anomalous magnetic moment, singularity in the relativistic equations generally occurs at the speed different from the speed of light.

description: Ces dernières années, l’utilisation d’additifs organiques, de métabolites naturels actifs ou de micro-organismes utiles fait l’objet de discussions en tant que stratégie écologique pour une production végétale plus durable. On observe dans le monde entier un intérêt croissant pour les inoculants microbiens et l’utilisation ciblée de leurs interactions avec les plantes.
 Les micro-organismes utiles peuvent en effet favoriser la croissance des végétaux en augmentant leur tolérance aux conditions défavorables du sol et de l’environnement ou en améliorant leur capacité de stockage de nutriments. Toutefois, le développement d’inoculants microbiens spécifiques, appelés biofertilisants, dotés d’effets bénéfiques s’avère très difficile. L’un des défis en particulier est l’adéquation entre applications agricoles et diverses conditions environnementales
 Certains biofertilisants commercialisés actuellement sont de mauvaise qualité ou leur application est compliquée. Autant d’inconvénients qui entraînent une perte de confiance des agriculteurs et des agricultrices. Néanmoins, l’amélioration de la qualité des formulations microbiennes et les progrès réalisés dans la compréhension des mécanismes biologiques ont contribué à accroître progressivement la rentabilité des applications au champ. Cette fiche résume les dernières avancées de la recherche en la matière.

description: Recently, IoT technologies have been progressed, and many sensors and actuators are connected to networks. Previously, IoT services were developed by vertical integration style. But now Open IoT concept has attracted attentions which achieves various IoT services by integrating horizontal separated devices and services. For Open IoT era, we have proposed the Tacit Computing technology to discover the devices with necessary data for users on demand and use them dynamically. We also implemented elemental technologies of Tacit Computing. In this paper, we propose three layers optimizations to reduce operation cost and improve performance of Tacit computing service, in order to make as a continuous service of discovered devices by Tacit Computing. In optimization process, appropriate function allocation or offloading specific functions are calculated on device, network and cloud layer before full-scale operation.

description: The nearest lattice point problem in $\mathbb{R}^n$ is formulated in a distributed network with $n$ nodes. The objective is to minimize the probability that an incorrect lattice point is found, subject to a constraint on inter-node communication. Algorithms with a single as well as an unbounded number of rounds of communication are considered for the case $n=2$. For the algorithm with a single round, expressions are derived for the error probability as a function of the total number of communicated bits. We observe that the error exponent depends on the lattice structure and that zero error requires an infinite number of communicated bits. In contrast, with an infinite number of allowed communication rounds, the nearest lattice point can be determined without error with a finite average number of communicated bits and a finite average number of rounds of communication. In two dimensions, the hexagonal lattice, which is most efficient for communication and compression, is found to be the most expensive in terms of communication cost.

description: In the classical Steiner tree problem, given an undirected, connected graph $G=(V,E)$ with non-negative edge costs and a set of \emph{terminals} $T\subseteq V$, the objective is to find a minimum-cost tree $E' \subseteq E$ that spans the terminals. The problem is APX-hard; the best known approximation algorithm has a ratio of $ρ= \ln(4)+\varepsilon < 1.39$. In this paper, we study a natural generalization, the \emph{multi-level Steiner tree} (MLST) problem: given a nested sequence of terminals $T_{\ell} \subset \dots \subset T_1 \subseteq V$, compute nested trees $E_{\ell}\subseteq \dots \subseteq E_1\subseteq E$ that span the corresponding terminal sets with minimum total cost. The MLST problem and variants thereof have been studied under various names including Multi-level Network Design, Quality-of-Service Multicast tree, Grade-of-Service Steiner tree, and Multi-Tier tree. Several approximation results are known. We first present two simple $O(\ell)$-approximation heuristics. Based on these, we introduce a rudimentary composite algorithm that generalizes the above heuristics, and determine its approximation ratio by solving a linear program. We then present a method that guarantees the same approximation ratio using at most $2\ell$ Steiner tree computations. We compare these heuristics experimentally on various instances of up to 500 vertices using three different network generation models. We also present various integer linear programming (ILP) formulations for the MLST problem, and compare their running times on these instances. To our knowledge, the composite algorithm achieves the best approximation ratio for up to $\ell=100$ levels, which is sufficient for most applications such as network visualization or designing multi-level infrastructure.

description: Pillow is the Python Imaging Library that adds image processing capabilities to the Python interpreter. It provides extensive file format support, an efficient internal representation, and fairly powerful image processing capabilities. In the past decades, there has been an increasing tendency for vulnerabilities reported to NVD, but not all of the vulnerabilities have been reported and patched in time. In order to fill the gap, we collect 14944 commits from Pillow repositories and conduct a thorough empirical study of the commits in Pillow, distinguishing security commits from non-security and bugfix commits. Leveraging the diverse set of information from commit message and code difference, we conduct an analysis of various aspects of the patch development life cycle, including an investigation into the duration, and the timeliness of patch development. We then characterize the nature of security fixes in comparison to other non-security bug fixes, exploring the complexity of different types of patches and their impact on Pillow. Furthermore, we carried out investigations on patches over various language pairs, gaining insights into the principles of cross-language combinations through semantic and syntactic perspectives. Our research provides some insights into identifying security commits in time and calls for more attention to ensuring timely fixes for vulnerabilities.

description: Wireless systems are increasingly used for Machine-Type Communication (MTC), where the users sporadically send very short messages. In such a setting, the overhead imposed by channel estimation is substantial, thereby demanding noncoherent communication. In this paper we consider a noncoherent setup in which users randomly access the medium to send short messages to a common receiver. We propose a transmission scheme based on Gabor frames, where each user has a dedicated codebook of M possible codewords, while the codebook simultaneously serves as an ID for the user. The scheme is used as a basis for a simple protocol for collision resolution.

description: The non-equilibrium annealing of structural disorder in a two-dimensional XY-model leads to coarsening of defects clusters in a cores of spin vortices. We revealed the effect of "inertial" growth of the clusters in coarsening dynamic regime. The calculated transverse stiffness $ρ(p,T)$ of the system in the high-temperature phase $T>T_{\rm BKT}(p)$ becomes negative and has described by a power low $ρ(p,T) \sim T^{-κ}$ with temperature independent exponent $κ=κ(p)$. The dynamical scaling lead to the dynamic dependence of the correlation length $ξ\sim (t / \ln^{q} (t/t_{0}))^{1/z}$ which can be explained by a shift of spin vortices friction constant $γ$ induced by annealed disorder.

description: Venezuelan Equine Encephalitis Virus (VEEV) is a mosquito-borne pathogen that commonly infects equines but has transmitted to humans in certain cases. The lack of small molecule antivirals for treatment against VEEV prompted a high throughput screen (HTS), which led to a hit molecule we dubbed DP9. To synthesize DP9 and analogs, we devised a two-step reaction approach comprising hipurric acid condensation and lactone amidation. In step 1, hipurric acid was refluxed with three different aldehydes in acetic anhydride to afford a handful of lactone intermediates. In step 2, two different amidation procedures were developed which allowed for lactone ring opening by amine nucleophiles, modifying the hipurric acid scaffold. Together, the aforementioned two-step sequence provided a diverse series of 8 DP9 analogs, which were fully characterized by 1H and 13C NMR, MS, and LC-UV purity trace. The modulation of aldehyde substituents in step 1 and amine tails in step 2 explores different aromatic electronics, lengths, size, and number of hydrogen-bond donors/acceptors. DP9 analogs inhibitory activity against VEEV was quantified using an alpha-screen assay.

title: Das Wörtchen eh aus multiperspektivischer Sicht
Creators: name: Ogura, Azusa
Year: 2021

description: Diese Masterarbeit untersucht das Wort eh aus multiperspektivischer – d. h. grammatischer und soziolinguistischer – Sicht. Dabei wird folgenden Forschungsfragen nachgegangen: Welche formalen und funktionalen Merkmale weist das Wort eh auf und welchen Wortarten können seine jeweiligen Verwendungsformen zugeschrieben werden? Inwiefern korrelieren grammatische / funktionale Merkmale von eh mit variationslinguistischen Faktoren, insbesondere der Standardsprachlichkeit? Den theoretischen Rahmen bilden dabei Ansätze funktional orientierter Grammatiken des Deutschen sowie Paradigmen der soziolinguistischen Sprachvariationsforschung, insbesondere deren Modellierung der „Plurizentrik“ und „Pluriarealität“ der deutschen Standardsprache. Als methodischer Zugang wurde eine hermeneutische Auswertung ausgewählter grammatischer und soziolinguistischer Fachliteratur unter Einbeziehung von beispielhaften Belegen aus in Österreich stattgefundener Chat-Kommunikation gewählt. Basierend darauf wurde eine grammatische Analyse von eh durchgeführt. Anhand der formalen und funktionalen Charakteristika der einzelnen Verwendungen des eh wurde dessen Wortartenzugehörigkeit diskutiert. Im zweiten Teil der Arbeit erfolgte auf Basis soziolinguistischer Grundlagen die Analyse einer möglichen „horizontal“- und „vertikal“-variativen Verteilung des eh. Als Ergebnis stellte sich heraus, dass eh nicht pauschal einer bestimmten Wortart zugeordnet werden kann. Syntaktisch gesehen lässt sich eh als Abtönungspartikel oder Responsiv klassifizieren, während hinsichtlich der funktionalen Merkmale keine eindeutige Wortartenzugehörigkeit bestätigt werden kann. Die Variante des eh als Synonym von sowieso weist eine konnektivpartikelähnliche Funktion auf, jedoch zeichnen sich die anderen Varianten, die keine Synonymität mit sowieso aufweisen, durch eine Funktion aus, die den Abtönungspartikeln zuzurechnen ist. Im Licht der soziolinguistischen Diskussion lässt sich vermuten, dass die Varianten des eh als Nicht-Synonym von sowieso vorrangig in „österreichischen“ Nonstandard-Varietäten auftreten.

description: A reliable extraction of filament data from microscopic images is of high interest in the analysis of acto-myosin structures as early morphological markers in mechanically guided differentiation of human mesenchymal stem cells and the understanding of the underlying fiber arrangement processes. In this paper, we propose the filament sensor (FS), a fast and robust processing sequence which detects and records location, orientation, length and width for each single filament of an image, and thus allows for the above described analysis. The extraction of these features has previously not been possible with existing methods. We evaluate the performance of the proposed FS in terms of accuracy and speed in comparison to three existing methods with respect to their limited output. Further, we provide a benchmark dataset of real cell images along with filaments manually marked by a human expert as well as simulated benchmark images. The FS clearly outperforms existing methods in terms of computational runtime and filament extraction accuracy. The implementation of the FS and the benchmark database are available as open source.

description: Understanding the interplay between black-hole accretion and star formation, and how to disentangle the two, is crucial to our understanding of galaxy formation and evolution. To investigate, we use a combination of optical and near-infrared photometry to select a sample of 74 quasars from the VISTA Deep Extragalactic Observations (VIDEO) Survey, over 1 deg$^2$. The depth of VIDEO allows us to study very low accretion rates and/or lower-mass black holes, and 26 per cent of the candidate quasar sample has been spectroscopically confirmed. We use a radio-stacking technique to sample below the nominal flux-density threshold using data from the Very Large Array at 1.4 GHz and find, in agreement with other work, that a power-law fit to the quasar-related radio source counts is inadequate at low flux density. By comparing with a control sample of galaxies (where we match in terms of stellar mass), and by estimating the star formation rate, we suggest that this radio emission is predominantly caused by accretion activity rather than star-formation activity.

description: One aspect of the digital divide relates to disparities in broadband infrastructure access among different individuals and communities. This divide creates significant inequalities, hindering some groups from fully participating in the digital world and accessing essential information and services. Additionally, political polarization surrounding broadband policies arises from differing views on the government's role in promoting equitable connectivity and fostering innovation. Understanding the sentiment surrounding broadband infrastructure and its connection to political ideology can offer valuable insights for addressing the digital divide and implementing effective policies to ensure broadband equality. A dataset of tweets was extracted from Twitter and organized into a CSV file. Utilizing the Textblob Natural Language Processing (NLP) tool, sentiment and polarity scores of each tweet were quantified to discern the prevailing attitudes and emotions expressed by users. Additionally, sentiment scores were cross-referenced with political ideology scores to uncover potential correlations between sentiment and users' political leanings. In doing so, minimal correlation between high and low ideology scores was discovered, with both ends of the spectrum mostly in favor of broadband expansion. However, tweets originating from those with low ideology scores (left leaning) were more numerous than those originating from those with high ideology scores (right leaning). This would seem to indicate a greater interest in broadband expansion from the left, but overall support across the political spectrum. One reason could be that Republicans, traditionally leaning towards smaller government and limited spending, might be hesitant to support large-scale government-funded initiatives, even in the face of broadband challenges in their communities. The observed disparity between Democrats' and Republicans' favorability to broadband expansion can be attributed to a combination of other factors which will be investigated further by comparing maps of broadband infrastructure to political electoral boundaries. Finally, the role of demographic factors, including age, gender, and location, were examined by visualizing scatterplots and comparing mean sentiment scores to understand how they might influence sentiments on broadband infrastructure and its proposed policy implementations. By analyzing these factors together, the study aims to illuminate the interplay between public opinion and political ideology on the necessity to foster broadband equality.

description: We consider evolution equations describing the scale dependence of the wave function of a baryon containing an infinitely heavy quark and a pair of light quarks at small transverse separations, which is the QCD analogue of the helium atom.The evolution equations depend on the relative helicity of the light quarks. For the aligned helicities, we find that the equation is completely integrable, that is it has a nontrivial integral of motion, and obtain exact analytic expressions for the eigenfunctions and the anomalous dimensions. The evolution equation for anti-aligned helicities contains an extra term that breaks integrability and creates a "bound state" with the anomalous dimension separated from the rest of the spectrum by a finite gap. The corresponding eigenfunction is found using numerical methods. It describes the momentum fraction distribution of the light quarks in, e.g., $Λ_b$-baryon at large scales.

description: Experiments on ultracold atomic gases have begun to explore lattice effects and thermal fluctuations for two-component bosons with spin-orbit coupling (SOC). Motivated by this, we study a $tJ$ model of strongly correlated lattice bosons, with equal Rashba-Dresselhaus SOC and a uniform magnetic field. At zero temperature, a Gutzwiller ansatz is shown to capture lattice variants of stripe superfluid (SF) ground states. We formulate a finite temperature generalization of the Gutzwiller approach and show that thermal fluctuations in the doped Mott insulator drive a two-step melting of the stripe SF, revealing a wide intermediate regime of a normal fluid with stripe order.

description: Additional file 6: Figure S4. Comparison of RNA-seq sample counts against the v2 and v3 assemblies and gene models. Principle component analyses (A) show tight clustering of sample replicates based on counts using both assemblies, while in the v3 (right) the Larvae, Scolex-Neck and Whole Adult samples are arrayed only along PC1, with the transcriptome of the Scolex-Neck mid-way between those of the Larvae and Whole Adult samples. The Mid and End samples are further differentiated from the other samples along PC2. Heatmap clustering (B) shows that the transcriptome of the Scolex-Neck region is more similar to that of mid-metamorphose larvae than to middle or end regions of the adult worm, as discussed in [8].
Complex Entangling Surfaces for AdS and Lifshitz Black Holes?

description: We discuss the possible relevance of complex codimension-two extremal surfaces to the the Ryu-Takayanagi holographic entanglement proposal and its covariant Hubeny-Rangamani-Takayanagi (HRT) generalization. Such surfaces live in a complexified bulk spacetime defined by analytic continuation. We identify surfaces of this type for BTZ, Schwarzschild-AdS, and Schwarzschild-Lifshitz planar black holes. Since the dual CFT interpretation for the imaginary part of their areas is unclear, we focus on a straw man proposal relating CFT entropy to the real part of the area alone. For Schwarzschild-AdS and Schwarzschild-Lifshitz, we identify families where the real part of the area agrees with qualitative physical expectations for the appropriate CFT entropy and, in addition, where it is smaller than the area of corresponding real extremal surfaces. It is thus plausible that the CFT entropy is controlled by these complex extremal surfaces.

title: Development of an H3+ Driven Chemical Ionization Source for GC-MS
Creators: name: Kroll, Kai Sven
Publisher: name: Bergische Universität Wuppertal
Year: 2021

description: In this work a novel plasma based chemical ionization (CI) source and its hyphenation with gas chromatography (GC) using a time-of-flight mass spectrometer (TOF MS) is developed. Classical electron beam driven chemical ionization sources often suffer from reduced filament lifetimes and thus require high maintenance efforts. Problems occur especially when using reactive and/or oxidizing reagent gases as well as due to reagent gas degradation product accumulation inside the ion source assembly.
 The alternative CI method developed in this work is based on the application of H3+ as primary charge-carrying species and its subsequent conversion via selective reaction cascades using reagent gases which then lead to ionization of the compound of interest. The H3+ ion is produced with high efficiency in a hydrogen plasma driven with a helical resonator. Since the proton affinity of H2 is much lower than that of almost all atoms and molecules, H3+ acts as a universal proton donor via a proton transfer reactions. The respective reagent ion formation of the three reagent gases nitrogen, methane, and isobutane were studied. In contrast to classical CI source operation, the formation of reagent ions and thus analyte ionization occurred mainly via proton transfer reactions. The quantitative transformation of H3+ into various reagent ion species allows to adjust the exothermicity of the analyte protonation reaction, minimizing the extent of fragmentation. The selectivity and sensitivity of the developed CI method is evaluated for various compounds.
 The ion source development process is discussed in detail. Four iteratively developed ion source designs were investigated. The performance of each ion source setup is carefully assessed. The final chemical ionization source design exhibits low picogram- to upper femtogram-on-column sensitivity and chromatographic peaks of Gaussian shape with full width at half maximum (FWHM) of < 1 s even for high boiling compounds of a fatty acid methyl ester (FAME) mixture. The customized helical resonator plasma source provides excellent long-term stability and requires low maintenance, while consisting of simple and low-cost hardware.

Assessing the performance of machine learning models at predicting demographics from satellite imagery

description: Deep learning, a subset of machine learning, has seen enormous growth in recent years, enabling deep learning models to comprehend abstract details and understand context with high accuracy. Consequently, deep learning holds significant promise for a wide range of applications, particularly in GIS applications where population estimates demand accuracy and a wealth of abstract decision making on a huge scale. However, the sheer size of incoming data causes deep learning models to escalate computational cost and complexity which results in many prerequisites and a lengthy processing time, potentially making shallow machine learning models a more viable choice. With that in mind, the aim of this study is to compare a classical random forest machine learning model with a model that leverages convolutional neural networks (CNNs) for population estimation. We apply this approach by trying to predict the on-the-ground demographics of local areas using satellite imagery. For example, it is expensive in time and money to undertake detailed population surveys, therefore open-source datasets from reputable outlets such as WorldPop, commonly use such a predictive approach. Our research explores the potential for traditional shallow machine learning models to still hold precedence over newer deep learning applications given their superior logistical prerequisites while having comparable accuracy on curtain applications.

description: These results complete our paper in Hiroshima Mathematical Journal, vol. 42, pp. 37-75. Let C be a covering of the plane by disjoint complete folding curves which satisfies the local isomorphism property. We show that C is locally isomorphic to an essentially unique covering generated by an $\infty$-folding curve. We prove that C necessarily consists of 1, 2, 3, 4 or 6 curves. We give examples for each case; the last one is realized if and only if C is generated by the alternating folding curve or one of its successive antiderivatives. We also extend the results of our previous paper to another class of paperfolding curves introduced by M. Dekking.
