description: The use of the pronoun ich (‘I’) in academic language is a source of constant debate and a frequent cause of insecurity for students. We explore manually annotated instances of I from a German learner corpus. Using machine learning techniques, we investigate to what extent it is possible to automatically distinguish between different types of I usage (author I vs. narrator I). We additionally inspect which context words are good indicators of one type or the other. The results show that an automatic classification is not straightforward, but the distinctive features are in line with previous research. The results of the automatic classification are not perfect, but would greatly facilitate manual annotation. The distinctive words are in line with previous research and indicate that the author I is a more homogeneous class.

description: Before the last decade, production units and its related systems were considered nearly as island systems and were managed as an air-gaped in their daily operations. Information and network security was not an issue because their plant's safety and continues operations have the highest priority. In the recent years, many initiatives like smart factories, adopting Industry 4.0, complex mesh of connected devices and data privacy have shifted paradigm of value chain and trust model in the production environment. By this means, state-of-the-art manufacturing environment demands for the comprehensive framework and holistic approach to address cybersecurity that affects reliability of plant operations. Therefore, few standards are gradually evolving and are extended in to this field. The ISA/IEC 62443 is one of the standard series addresses the Security of Industrial Automation and Control Systems (IACS) throughout their lifecycle. On the other hand, NIST Special Publication 800–82 is a Guide to Industrial Control Systems Security and follows NIST CSF to address OT security. As with Operational Technology (OT) requirements in general, also considering to security-related requirements as per ISA/IEC 62443, ask for more effort to deal with it later. Accordingly, bearing in mind, the need for security from the beginning of the system engineering processes reduces the overall effort and complexity during the lifecycle of OT systems. The corresponding paradigm is called Security by Design. This paper proposes on how high level foundational security requirements from ISA/IEC 62443 can be modelled using AutomationML (AML) tool and consequently explains on how easy is to integrate seamlessly that model during the design phase of engineering process.

description: We have derived a variational principle that defines the nonequilibrium steady-state transport across a correlated impurity mimicking, e.g., a quantum dot coupled to biased leads. This variational principle has been specialized to a Gutzwiller's variational space, and applied to the study of the simple single-orbital Anderson impurity model at half filling, finding a good qualitative accord with the observed behavior in quantum dots for the expected regime of values of the bias. Beyond the purely theoretical interest in the formal definition of a variational principle in a nonequilibrium problem, the particular methods proposed have the important advantage to be simple and flexible enough to deal with more complicated systems and variational spaces.

description: The world of linear radio broadcasting is characterized by a wide variety of stations and played content. That is why finding stations playing the preferred content is a tough task for a potential listener, especially due to the overwhelming number of offered choices. Here, recommender systems usually step in but existing content-based approaches rely on metadata and thus are constrained by the available data quality. Other approaches leverage user behavior data and thus do not exploit any domain-specific knowledge and are furthermore disadvantageous regarding privacy concerns. Therefore, we propose a new pipeline for the generation of audio-based radio station fingerprints relying on audio stream crawling and a Deep Autoencoder. We show that the proposed fingerprints are especially useful for characterizing radio stations by their audio content and thus are an excellent representation for meaningful and reliable radio station recommendations. Furthermore, the proposed modules are part of the HRADIO Communication Platform, which enables hybrid radio features to radio stations. It is released with a flexible open source license and enables especially small-and medium-sized businesses, to provide customized and high quality radio services to potential listeners.
Brane-induced Skyrmion on S^3: baryonic matter in holographic QCD

description: We study baryonic matter in holographic QCD with D4/D8/\bar{D8} multi-D brane system in type IIA superstring theory. The baryon is described as the "brane-induced Skyrmion", which is a topologically non-trivial chiral soliton in the four-dimensional meson effective action induced by holographic QCD. We employ the "truncated-resonance model" approach for the baryon analysis, including pion and ρmeson fields below the ultraviolet cutoff scale M_KK \sim 1GeV, to keep the holographic duality with QCD. We describe the baryonic matter in large N_c as single brane-induced Skyrmion on the three-dimensional closed manifold S^3 with finite radius R. The interactions between baryons are simulated by the curvature of the closed manifold S^3, and the decrease of the size of S^3 represents the increase of the total baryon-number density in the medium in this modeling. We investigate the energy density, the field configuration, the mass and the root-mean-square radius of single baryon on S^3 as the function of its radius R. We find a new picture of "pion dominance" near the critical density in the baryonic matter, where all the (axial) vector meson fields disappear and only the pion field survive. We also find the "swelling" phenomena of the baryons as the precursor of the deconfinement, and propose the mechanism of the swelling in general context of QCD. The properties of the deconfinement and the chiral symmetry restoration in the baryonic matter are examined by taking the proper order parameters. We also compare our truncated-resonance model with another "instanton" description of the baryon in holographic QCD, considering the role of cutoff scale M_KK.

description: Being one of the most significant and valuable coral reef systems in the South China Sea, the Xisha Islands has undergone rapid transformation due to increasing stressors from human impacts and climate change in recent years. However, as indispensable information for coral reef monitoring and management, the detailed reef extent, geomorphic zonation, or benthic composition of the Xisha Islands is not well documented. Considering limited access to the Xisha Islands, the rapid development of optical remote sensing technology provides us with a feasible mean for coral reef observation. This study adopted a water depth substitution index – probabilistic inundation (PI) – combined with depth-invariant index (DII) to achieve reef extent exploration, geomorphologic and benthic habitat types classification with unsupervised classification algorithms based on Landsat-8 time-series satellite data. Compared with two open-access datasets, the extent of each independent reef extracted from PI exhibited higher similarity with the actual boundary conditions displayed in RGB (Red-Green-Blue) composite images from Landsat-8. Based on PI and derived slope, we obtained geomorphic zonation classification results, and similarly benthic compositions were retrieved based on PI, DII, and reflectance. The overall accuracy of geomorphic zonation and benthic habitat classification results were 72% and 86%, respectively. We also interestingly discovered that corals of the Xisha Islands may be capable of an ability to resist chronic heat stress as a growth trend of reef area after two successive stress events in 2014–2015 were observed at most reefs. The proposed mapping framework of this study provides a repeatable and flexible scheme in depicting the comprehensive situation of coral reefs at Xisha Islands based only on publicly available remote sensing data without complicated pre-set parameters, which could be easily extended to coral reef research around the world. Simultaneously, the findings also provide requisite information supporting the sustainable management and conservation of coral reef ecosystems in the Xisha Islands.
Giant spin rotation in the normal metal/quantum spin Hall junction

description: We study theoretically reflection problem in the junction between a normal metal and an insulator characterized by a parameter $M$, which is a usual insulator for $M>0$ or a quantum spin Hall system for $M<0$. The spin rotation angle $α$ at the reflection is obtained in the plane of $M$ and the incident angle $θ$ measured from the normal to the interface. The $α$ shows rich structures around the quantum critical point M=0 and $θ=0$, i.e., $α$ can be as large as $\sim π$ at an incident angle in the quatum spin Hall case $M<0$ because the helical edge modes resonantly enhance the spin rotation, which can be used to map the energy dispersion of the helical edge modes. As an experimentally relevant system, we also study spin rotation effect in quantum spin Hall/normal metal/quantum spin Hall trilayer junction.

description: At many charging stations, the charging process of battery electric vehicles (BEV) takes significantly more time than refilling a gas tank. In combination with the lack of charging stations, this results in more planning effort for drivers who have to find a free charging station. In addition, charging draws a significant amount of energy from the power grid so that operators might have to coordinate charging to avoid congestion. Such problems are especially relevant at workplaces, where the employer might offer many charging stations for employees with similar working hours. An approach to overcome these problems lies in the management of the existing infrastructure using data-driven strategies. Accurate forecasts on the occupancy of charging stations allow allocating available resources more efficiently. This work aims to find suitable methods to predict the occupancy of single charging stations, given their historical data. The forecasts could be used as an input in decision support for drivers or energy management systems of charging station operators. This paper discusses feature importance, transferability between multiple charging stations at one location, and how the characteristics of charging stations influence the predictability of their occupancy. We use 52 charging stations from the open ACN data set to evaluate the research questions. The data set has more than 24,000 charging events and is located at a research facility so that it resembles workplace parking. Finally, we test the forecast on new, previously unseen data to ensure the findings hold-up in a realistic scenario.
Japan's security policy during the Ikeda Cabinet (1960-1964)
Creators: name: Takemoto, Toru
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is the result of research on the nature of Japan's security policy as pursued by the Ikeda Cabinet during I960 and 1964. The main discussion consists of three parts: internal political impacts on security policy making; external political impacts on security policy of Japan; and Japan's security policy proper. Three political parties are studied as significant determinants of internal political impacts on the decision making structure of the Japanese political system. The rationale is that these political parties provide channels that connect the decision making core and the outer area of the Japanese political system. Therefore, the study of these political parties is a rewarding attempt at observing political inputs that the decision making core of the Japanese political system receives. International exchange of the Japanese political system is investigated in the second part of the discussion. This subject is viewed both as inputs and outputs of the Japanese political system in relation to its international environment. The nature of the external impacts such as military, economic, geographic, ideological or cultural impacts is not specified in the following discussion, but is viewed as a Gestalt, or total being which comprises all the elements stated above. The third section deals with what is usually described as defence policy. A more military aspect of Japan's security policy is studied in this section. In conclusion, a broad generalisation is derived from the survey cited in the main discussion. The conclusion is characterised as the principle of balance in the Ikeda Cabinet's security policy.

description: Physicians must participate in continuing medical education (CME) as part of the medical quality assurance. One possibility is to take online courses in their private living environment. These courses are mostly text-or video-based. Novel technologies such as mobile Augmented (AR) or mobile Virtual Reality (VR) are not yet established although their usage is not out of bounds in private homes anymore. Game engines can facilitate the authoring of applications that utilize VR/AR, as they provide many crucial functionalities out of the box. However, integrating the resulting VR/AR software in online CME courses is not trivial. In this paper, we investigate this integration into an existing learning management system (LMS) for online CME. In the example of a mobile AR application, we propose a system design that extends a course by a mobile AR part. We describe our implementation and how we transition users from their familiar web-interface on the desktop PC to a mobile AR application.

In vielen Fällen werden dabei auch private und/oder sensible Informationen verarbeitet. Da selbstlernende Verfahren in der Regel auf sich nicht überschneidenden Datenmengen trainiert und später angewendet werden, ging man lange davon aus, dass es nicht möglich sei, vom finalen Modell Rückschlüsse auf die zum Training verwendeten Daten zu ziehen. Ergebnissen aus der jüngeren Forschung demonstrieren jedoch, dass es sich bei dieser Annahme um einen Trugschluss handelt. Die vorliegende Arbeit erläutert welche Risiken sich für die Privatheit des Einzelnen im Rahmen von maschinellen Lernverfahren ergeben und wie dem unerwünschten Abgreifen von sensiblen Informationen bereits in der Trainingsphase entgegen gesteuert werden kann.
Quotients of the conifold in compact Calabi-Yau threefolds, and new topological transitions

description: The moduli space of multiply-connected Calabi-Yau threefolds is shown to contain codimension-one loci on which the corresponding variety develops a certain type of hyperquotient singularity. These have local descriptions as discrete quotients of the conifold, and are referred to here as hyperconifolds. In many (or possibly all) cases such a singularity can be resolved to yield a distinct compact Calabi-Yau manifold. These considerations therefore provide a method for embedding an interesting class of singularities in compact Calabi-Yau varieties, and for constructing new Calabi-Yau manifolds. It is unclear whether the transitions described can be realised in string theory.

 Xiphidiopsis bifurcata: Liu & Bi, 1994, Acta Zootaxonomica Sinica, 19(3): 329.
 Discussion: Nefateratura was proposed for a species bearing unpaired terminal projections on the male 10th abdominal tergite as a subgenus of Alloteratura. Alloteratura mesembrina Kevan & Jin, 1993 was also included. Gorochov (2008) elevated the subgenus to generic rank together with Indoteratura and questioned the status of Nefateratura mesembrina because its male genitalia were very similar to those of the genus Decma. Xiphidiopsis bifurcata is allied to the type species owing to: the unpaired projection of male 10th abdominal tergite, the elongate male cerci (Figs. 69–74); paired bands of the vertex and pronotum (Figs. 66, 67); the strongly projecting and sclerotized male genitalia (Figs. 69–74); and they all from southern Xizang.

description: The spectral properties of the Laplacian on a class of quantum graphs with random metric structure are studied. Namely, we consider quantum graphs spanned by the simple $\ZZ^d$-lattice with $δ$-type boundary conditions at the vertices, and we assume that the edge lengths are randomly independently identically distributed. Under the assumption that the coupling constant at the vertices does not vanish, we show that the operator exhibits the Anderson localization at the bottom of the spectrum almost surely. We also study the case of other spectral edges.

description: Electrostatic forces between small groups of colloidal particles are measured using blinking optical tweezers. When the electrostatic screening length is significantly larger than the particle radius, forces are found to be non-pairwise additive. Both pair and multi-particle forces are well described by the linearized Poisson-Boltzmann equation with constant potential boundary conditions. These findings may play an important role in understanding the structure and stability of a wide variety of systems, from micron-sized particles in oil to aqueous nanocolloids.

description: We point out that if quantum field renormalization is taken into account, and the counterterms are evaluated at the Hubble-radius crossing time or few e-foldings after it, the predictions of slow-roll inflation for both the scalar and tensorial power spectrum change significantly. This leads to a change in the consistency condition that relates the tensor-to-scalar amplitude ratio with spectral indices. A reexamination of the potentials $\bf{ϕ^2, ϕ^4}$, shows that both are compatible with five-year WMAP data. Only when the counterterms are evaluated at much larger times beyond the end of inflation one recovers the standard predictions. The alternative predictions presented here may soon come within the range of measurement of near-future experiments.

description: Excerpts from the report: Frozen food locker plants operating in the United States in January 1958 totaled 9,611 [corrected]. This is a drop of 283 plants below last year. Iowa again led with 708 plants, Washington came second with 626 and Minnesota third with 602. California, Washington, Michigan, and Illinois registered the greatest decline in number of plants. The frozen food locker industry is continuing to change in the nature and scope of its activities. It is moving from custom processing and locker rental services toward commercial processing and merchandising. The broadened activities include service to home freezer users, local institutions, and small retail stores. While the number of plants has declined by about 2,000 since the peak year of 1951, the industry has added processing facilities, expanded slaughtering and processing, increased volume of food sold, and increased the number of patrons served.

description: We consider a planar system of fermions, at finite temperature and density, under a static magnetic field parallel to the two-dimensional plane. This magnetic field generates a Zeeman effect and, then, a spin polarization of the system. The critical properties are studied from the Landau's free energy. The possible observable consequences of the magnetization of planar systems such as polymer films and graphene are discussed.

description: Due to the increasing share of fluctuating renewable energy resources in the energy supply, the supply-demand balance needs to be increasingly supported by prosumers, who are able to adapt their energy demand and production depending on the current supply. Since small and medium-sized companies are expected to yield the potential for providing a significant share of the required flexibility, we propose an approach that enables an efficient development, testing and implementation of advanced control strategies and further data applications in decentralized energy supply systems of medium-sized companies to support the integration of such technologies and the increase of prosumer-side flexibility. The approach is based on an adaptable control framework, which is at first applied to a physical simulation model of the industrial energy system to test and train new control strategies and can afterwards be moved to the actual energy supply system of the plant.
A Markovian event-based framework for stochastic spiking neural networks

description: In spiking neural networks, the information is conveyed by the spike times, that depend on the intrinsic dynamics of each neuron, the input they receive and on the connections between neurons. In this article we study the Markovian nature of the sequence of spike times in stochastic neural networks, and in particular the ability to deduce from a spike train the next spike time, and therefore produce a description of the network activity only based on the spike times regardless of the membrane potential process. To study this question in a rigorous manner, we introduce and study an event-based description of networks of noisy integrate-and-fire neurons, i.e. that is based on the computation of the spike times. We show that the firing times of the neurons in the networks constitute a Markov chain, whose transition probability is related to the probability distribution of the interspike interval of the neurons in the network. In the cases where the Markovian model can be developed, the transition probability is explicitly derived in such classical cases of neural networks as the linear integrate-and-fire neuron models with excitatory and inhibitory interactions, for different types of synapses, possibly featuring noisy synaptic integration, transmission delays and absolute and relative refractory period. This covers most of the cases that have been investigated in the event-based description of spiking deterministic neural networks.
Entrepreneurship Centers: A Qualitative Study on Their Mission, Vision, and Support Services for Veteran Entrepreneurship in the United States

description: This research evaluates how Entrepreneurship Centers (EC) function within veteran friendly Higher Educational Institutions (HEI) located in the United States (US) capital. It includes all 17 HEIs in Washington, DC. The region stands out because of its veteran population and unique combination of federal agencies, policymakers, HEIs and veteran support organizations. The study focuses on evaluating ECs' educational quality and effectiveness for veteran entrepreneurship promotion as well as determining their added value and impact on entrepreneurship initiatives. Content analysis was used to evaluate the operation of ECs in veteran friendly HEI systems through their mission and vision statements and their programs that support inclusion and entrepreneurial opportunities for veterans. Data collection and analysis involves initial reading followed by open coding and thematic analysis of information from the university's website including ECs website and US Department of Education data. The research findings show that certain ECs at veteran friendly HEIs in Washington, DC offer comprehensive veteran support through programs that combine mentoring with financial assistance. Several ECs show minimal interest with little direct connection to veteran welfare.

description: As a result of the ongoing development of vehicle electronics and additional wireless communication interfaces, the possibilities for attacks and their negative consequences are increasing. Once an attacker has obtained access to the internal vehicle communication, in the case of the Controller Area Network (CAN) the attacker is able to forge all messages of the connected Electronic Control Units (ECUs) without a receiving ECU being able to recognize any suspicious behavior. The use of cryptographic methods is only possible to a limited extent due to restricted resources of the ECUs, which is why sender identification systems have been presented which are able to detect these kind of attacks. Presented approaches use different procedures to capture the analog signals on which the detection of attacks respectively the identification of the sender is based. This work shows that the impact on the performance of the sender identification system by the different sampling methods is minimal and therefore the selection of the appropriate technique can be mainly based on the available resources and the communication structure of the corresponding vehicle platform. This is shown on the one hand by the direct analysis of the analog signals captured from a real vehicle as well as by an evaluation of the previously introduced sampling methods using a recently published sender identification system. In addition, an assessment of the procedures based on different parameters shows which method is to be preferred for which application.
Understanding fish-habitat associations using video observations and sonar imaging

Subjects: Aquaculture and fisheries stock assessment

description: Planning for resilience is now a catch cry of many marine conservation programs and initiatives. These efforts are striving to inform conservation strategies for marine regions to ensure they have inbuilt capacity to retain biological diversity and ecological function in the face of global environmental change – particularly changes in climate and resource exploitation. A fundamental step in these strategies is to understand the distribution of species’ (or other biological entities) throughout the focal region. However, in the absence of direct biological and ecological information for many marine species, scientists are increasingly using spatially-explicit predictive modelling approaches. Through the improved access to multibeam echosounder (MBES) data and underwater video technology these models can provide spatial predictions of the most suitable regions for an organism at resolutions previously not possible. This thesis was motivated by the recognition of the potential role of species distribution models in managing marine fish species and their habitats. This thesis sets out to address four interlinked ideas in consecutive chapters, with their justification and outcomes briefly detailed below.

description: Citation recommendation aims to predict references based on a given text. In this paper, we focus on predicting references using small passages instead of a whole document. Besides using a search engine as baseline, we introduce two further more advanced approaches that are based on neural networks. The first one aims to learn an alignment between a passage encoder and reference embeddings while using a feature engineering approach including a simple feed forward network. The second model takes advantage of BERT, a state-of-the-art language representation model, to generate context-sensitive passage embeddings. The predictions of the second model are based on inter-passage similarities between the given text and indexed sentences, each associated with a set of references. For training and evaluation of our models, we prepare a large dataset consisting of English papers from various scientific disciplines.

description: We describe all linear operators on spaces of multivariate polynomials preserving the property of being non-vanishing in open circular domains. This completes the multivariate generalization of the classification program initiated by Pólya-Schur for univariate real polynomials and provides a natural framework for dealing in a uniform way with Lee-Yang type problems in statistical mechanics, combinatorics, and geometric function theory. This is an announcement with some of the main results in arXiv:0809.0401 and arXiv:0809.3087.

description: In this paper, we contribute an eye tracking study to evaluate the gaze behavior of e-scooter drivers and cyclists on high and low quality road surfaces. We recorded the surface quality with sensors and put the different surfaces in relation to the gaze behavior. We recorded eye movements of the participants and performed an Area of Interest (AOI) sequence analysis to identify gaze patterns. Found sequences show that on the high quality surface participants focused most commonly the distant road section and then shifted to nearer sections. Individual advantageous gaze sequences are omitted if the surface is poor. We found a significant difference in the attention distribution of the two means of transport. In addition, we can confirm previous results showing that low quality road surfaces cause the gaze to shift forward. However, the participants did not adapt their speed to the worse surface.

description: Let $S$ be a set of $n$ points in $\mathbb{R}^3$, no three collinear and not all coplanar. If at most $n-k$ are coplanar and $n$ is sufficiently large, the total number of planes determined is at least $1 + k \binom{n-k}{2}-\binom{k}{2}(\frac{n-k}{2})$. For similar conditions and sufficiently large $n$, (inspired by the work of P. D. T. A. Elliott in \cite{Ell67}) we also show that the number of spheres determined by $n$ points is at least $1+\binom{n-1}{3}-t_3^{orchard}(n-1)$, and this bound is best possible under its hypothesis. (By $t_3^{orchard}(n)$, we are denoting the maximum number of three-point lines attainable by a configuration of $n$ points, no four collinear, in the plane, i.e., the classic Orchard Problem.) New lower bounds are also given for both lines and circles.
