description: The machine learning (ML) and deep learning (DL) techniques are widely recognized to be powerful tools for virtual drug screening. The recently reported ML- or DL-based scoring functions have shown exciting performance in predicting protein-ligand binding affinities with fruitful application prospects. However, the differentiation between highly similar ligand conformations, including the native binding pose (the global energy minimum state), remains challenging which could greatly enhance the docking. In this work, we propose a fully differentiable framework for ligand pose optimization based on a hybrid scoring function (SF) combined with a multi-layer perceptron (DeepRMSD) and the traditional AutoDock Vina SF. The DeepRMSD+Vina, which combines (1) the root mean square deviation (RMSD) of the docking pose with respect to the native pose and (2) the AutoDock Vina score, is fully differentiable thus is capable of optimizing the ligand binding pose to the energy-lowest conformation. Evaluated by the CASF-2016 docking power dataset, the DeepRMSD+Vina reaches a success rate of 95.4%, which is by far the best reported SF to date. Based on this SF, an end-to-end ligand pose optimization framework was implemented to improve the docking pose quality. We demonstrated that this method significantly improves the docking success rate (by 15%) in redocking and crossdocking tasks, revealing the high potentialities of this framework in drug design and discovery.

description: We propose that CaP3 family of materials, which include CaP3, CaAs3, SrP3, SrAs3 and BaAs3 can host a three-dimensional topological nodal line semimetal states. Based on first-principle calculations and kp model analysis, we show that a closed topological nodal line exists near the Fermi energy, which is protected by the coexistence of time-reversal and spatial inversion symmetry when the band inversion happens. A drumhead-like surface states are also obtained on the c-direction surface of these materials.

Publisher: name: Leipziger Universitätsverlag

description: The Organisation for Economic Co-operation and Development (OECD) and its predecessor, the Organisation for European Economic Co-operation (OEEC), are widely regarded as paradigmatic “Western” international organizations, essentially defining what it means to be a modern capitalist state. Focusing on transnational debates about development aid within the OEEC and OECD in the 1950s and 190s, this article analyses, in the context of Cold War and decolonization, how the “West” was constructed among experts, how they managed intra-European discrepancies between the richer “Northern” European and the poorer “Southern” European countries, and how these were conceptualized in relation to non-member countries from the global “South”. It shows how development aid within the OEEC emerged simultaneously from the apparatus of its colonial powers and from the need to handle an intra-European “North-South” divide. The article further argues that within this economic organization the rift between richer and poorer countries running through Western Europe was primarily couched in a technical and economic language in which the categories “developed” and “underdeveloped” were central concepts. The expert debates defined a region with specific characteristics – economically backwards, poor, and structurally lagging behind the richer OECD countries – thereby establishing a discourse that, from the 1970s onwards, powerfully shaped the explicitly geographic social scientific concept of “Southern” Europe.

description: The dynamics of social relations and the possibility of reaching the state of structural balance (Heider balance) under the influence of the temperature modeling the social noise level are discussed for interacting actors occupying nodes of classical random graphs. Depending on the graph density $D$, either a smooth cross-over or a first-order phase transition from a balanced to an imbalanced state of the system is observed with an increase of the thermal noise level. The minimal graph density $D_\text{min}$ for which the first-order phase transition can be observed decreases with system size $N$ as $D_\text{min}\propto N^{-0.58(1)}$. For graph densities $D>D_\text{min}$ the reduced critical temperature $T_c^\star=T_c/T_c(D=1)$ increases with the graph density as $T_c^\star\propto D^{1.719(6)}$ independently of the system size $N$.

description: Perpendicular magnetic anisotropy (PMA) is a key property of magnetoresistive random access memory (MRAM). To increase areal density of MRAM it is important to find a way to enhance the PMA. Recently a strong enhancement of the PMA by inserting an ultrathin LiF layer at an Fe/MgO interface was reported [T. Nozaki et al., NPG Asia Materials (2022) 14: 5]. To understand the origin of the observed enhancement of the PMA we perform first-principles calculations of magetocrystalline anisotropy energy (MAE) of the following four kind of multilayer structures: Fe/MgO, Fe/LiF/MgO, Fe/FeO/MgO, and Fe/FeF/LiF/MgO. We find that the MAEs of the Fe/LiF/MgO and the Fe/FeF/LiF/MgO structures are almost the same as that of the Fe/MgO structure, while the MAE of the Fe/FeO/MgO structure is less than a half of that of the Fe/MgO structure. The results show that the major origin of the enhancement of the PMA obtained by inserting an ultrathin LiF layer at an Fe/MgO interface is the suppression of the mixing of Fe and O atoms at the interface. We also find that the in-plane Fe-F coupling gives a positive contribution to the MAE while the in-plane Fe-O coupling gives a negative contribution. The results are useful for designing of high-PMA materials.

Dazu analysiert der Beitrag die Strategien und Mechanismen, die es den beiden Stiftungen als Nichtregierungsorganisationen erlaubten, sich einflussreiche Positionen in der internationalen Politik zu sichern. Der Antikommunismus in den USA ebenso wie die außenpolitischen Vorgaben Washingtons stellten hierbei Bedingungen, zu denen sich die Stiftungen explizit verhalten mussten. Zugleich erwiesen sie sich als geschickt darin, eigene Strukturen zu nutzen und neue herzustellen, die ihre Position in einem zunehmend kompetitiven Feld wie der Entwicklungspolitik stabilisierten.

description: In the present study, we investigate the interaction between dark energy and dark matter, particularly emphasizing the effects of curvature in the realm of Friedmann-Lemaitre-Robertson-Walker (FLRW) space-time. We examine the system by forming a dynamic set of equations for various critical points. Later, we study their stability characteristics and show that with a suitable choice of potential, the system gives rise to the late-time attractor (stable) solution in the expanding environment. Lastly, we present the cosmological compatibility of the model using the phase-space portrait tools.

description: Despite their exceptional flexibility and popularity, the Monte Carlo methods often suffer from slow mixing times for challenging statistical physics problems. We present a general strategy to overcome this difficulty by adopting ideas and techniques from the machine learning community. We fit the unnormalized probability of the physical model to a feedforward neural network and reinterpret the architecture as a restricted Boltzmann machine. Then, exploiting its feature detection ability, we utilize the restricted Boltzmann machine for efficient Monte Carlo updates and to speed up the simulation of the original physical system. We implement these ideas for the Falicov-Kimball model and demonstrate improved acceptance ratio and autocorrelation time near the phase transition point.

description: We measure the extinction law in the 30 Dor star formation region in the Large Magellanic Cloud using Early Release Observations taken with Near-Infrared Camera (NIRCam) onboard the JWST, thereby extending previous studies with the Hubble Space Telescope to the infrared. We use red clump stars to derive the direction of the reddening vector in twelve bands and present the extinction law in this massive star forming region from $0.3$ to $4.7\,μ$m. At wavelengths longer than 1 $μ$m, we find a ratio of total and selective extinction twice as high as in the diffuse Milky Way interstellar medium and a change in the relative slope from the optical to the infrared domain. Additionally, we derive an infrared extinction map and find that extinction closely follows the highly embedded regions of 30 Dor.

description: Dieser Artikel untersucht die Rolle der United Nations Economic Commission for Europe (UNECE) aus der von Giddens‘ entwickelten Perspektive der Dualität von Struktur und Handlung. Häufig werden Internationale Organisationen (IOs) als Ausdruck der gesammelten Interessen ihrer nationalstaatlichen Mitglieder und damit letztlich als entscheidungsschwach dargestellt. Stattdessen argumentiert dieser Artikel, dass IOs durchaus über agency und eine eigene Agenda verfügen. Dies wird am Beispiel der UNECE deutlich, die ursprünglich als Steuerungsgremium für den europäischen Wiederaufbau konzipiert war. Am Beispiel von internen Aushandlungsprozessen zeigt der Artikel, dass die UNECE sowohl ein Resultat des Kalten Krieges als auch ein wirkmächtiger Akteur in diesem Konflikt war.

description: This paper addresses the problem of improving response times of robots implemented in the Robotic Operating System (ROS) using formal verification of computational-time feasibility. In order to verify the real time behaviour of a robot under uncertain signal processing times, methods of formal verification of timeliness properties are proposed for data flows in a ROS-based control system using Probabilistic Timed Programs (PTPs). To calculate the probability of success under certain time limits, and to demonstrate the strength of our approach, a case study is implemented for a robotic agent in terms of operational times verification using the PRISM model checker, which points to possible enhancements to the operation of the robotic agent.

description: Die bisherige Forschungstradition zur kommunistischen Machtübernahme in Ostmittel- und Osteuropa zwischen 1944 und 1948 betonte den gewalttätigen und zerstörerischen Charakter der Maßnahmen, mit denen die kommunistischen Parteien ‚totale Kontrolle‘ zu erringen versuchten. Der vorliegende Artikel nimmt stattdessen eine Perspektive ein, die staatliche Institutionen als konkrete Handlungsorte begreift, in denen Konflikte zwischen historischen Akteuren ausgetragen wurden, welche die Verschiebung der Macht erst ermöglichten. Vor diesem Hintergrund untersucht der Artikel die Personalpolitik in den Sicherheitsapparaten der Sowjetischen Zone Deutschlands und Rumäniens. Angeleitet ist die Analyse von der auf Anthony Giddens‘ Konzept der Strukturierung basierenden Annahme, dass institutionelle Strukturen nur so lange existieren können, wie individuelle Akteure willens und bereit sind, sie aktiv zu füllen und zu reproduzieren.

description: In this article, we have done a thorough investigation of the possible effects of interaction between dark matter (DM) and neutrinos on reionization history. We have constrained the interaction strength using 21 cm Cosmology and found out possible deviations from standard, non-interacting $Λ$CDM scenario. Comparing the results with the existing constraints from present cosmological observations reveals that 21 cm observations are more competent to constrain the interaction strength by a few orders of magnitude. We have also searched for prospects of detecting any such interaction in the upcoming 21 cm mission SKA1-Low by doing a forecast analysis and error estimation.

description: Dieser Artikel hinterfragt die Erklärungskraft des historischen Institutionalismus für die Interpretation institutionellen Wandels. Dazu wird ein dezentrierter Ansatz vorgestellt, der die individuelle agency von Akteuren konzeptualisiert und historisiert. Als Fallstudie dienen außerparlamentarische Gremien in der Zwischenkriegszeit in Westeuropa und in den Niederlanden. Indem diese Organisationen und die in ihnen handelnden Personen aus einer Mikroperspektive untersucht werden, wird gezeigt, dass Erklärungen institutionellen Wandels mit der situated agency der historischen Akteure verbunden werden müssen. Damit steht er Interpretationen entgegen, die sich auf die Makroebene konzentrieren und institutionellen Wandel als evolutionär betrachten.

description: As a natural extension of link prediction on graphs, hyperlink prediction aims for the inference of missing hyperlinks in hypergraphs, where a hyperlink can connect more than two nodes. Hyperlink prediction has applications in a wide range of systems, from chemical reaction networks, social communication networks, to protein-protein interaction networks. In this paper, we provide a systematic and comprehensive survey on hyperlink prediction. We propose a new taxonomy to classify existing hyperlink prediction methods into four categories: similarity-based, probability-based, matrix optimization-based, and deep learning-based methods. To compare the performance of methods from different categories, we perform a benchmark study on various hypergraph applications using representative methods from each category. Notably, deep learning-based methods prevail over other methods in hyperlink prediction.

description: Die Einleitung versteht sich als ein Annäherungsversuch an eine kontextsensible und theoretisch informierte Institutionengeschichte. Ausgangspunkt ist die Überlegung, wie es gelingen kann, Organisationen auch in Phasen rapiden Wandels sowohl als eigenständige Einheiten zu analysieren als auch in Relation zu ihren komplexen Umwelten zu begreifen. In einem ersten Schritt werden zentrale institutionen- und organisationstheoretische Konzepte verschiedener Fachdisziplinen aufgegriffen und auf ihren Nutzen und ihre Anwendungsmöglichkeiten für die empirische historische Forschung hin betrachtet. Diese werden mit bestehenden historiographischen Debatten verbunden. In einem zweiten Schritt ordnet der Beitrag die hier präsentierten Fallstudien in diese Diskussion ein und formuliert einige übergreifende Befunde für die zukünftige institutionengeschichtliche Forschung.

description: Compact Hierarchical Triples (CHT) are systems with the tertiary star orbiting the inner binary in an orbit shorter than 1000 days. CHT with an eclipsing binary as its inner binary can help us extract a multitude of information about all three stars in the system. In this study, we use independent observational techniques to estimate the orbital, stellar, and atmospheric parameters of two triple-lined CHT: BD+442258 and KIC06525196. We find that the masses of stars in BD+442258 are $1.011\pm0.029 M_{\odot}$, $0.941\pm0.033 M_{\odot}$, and $0.907\pm0.065 M_{\odot}$ while in KIC06525196 the estimated masses are $1.0351\pm0.0055 M_{\odot}$, $0.9712\pm0.0039 M_{\odot}$, and $0.777\pm0.012 M_{\odot}$. Using spectral disentangling, we obtained individual spectra of all the stars and combined them with light curve modeling to obtain radii, metallicities, and temperatures. Using stellar evolution models from MESA, we constrain the log(age) of BD+442258 to be 9.89 and 9.49 for KIC06525196. Two stars in BD+442258 are found to be sub-giants while all three stars in KIC06525196 are main-sequence stars. We constrain the mutual inclinations to certain angles for BD+442258 and KIC06525196 using numerical integration. Integrating with tidal interaction schemes and stellar evolution models, we find that KIC06525196 is a stable system. But the inner binary of BD+442258 merges within 550 Myrs. The time of this merger is affected by the orientation of the tertiary, even rushing the collapse by 100 Myrs when the mutual inclination is close to 90 degrees.

Die mobility studies jedoch nehmen beide Phänomene gemeinsam in den Blick und können so die oft fließenden Grenzen und vielfältigen Überschneidungen zwischen Migration und Tourismus sichtbar machen. Der Kommentar diskutiert verschiedene Tourismusformen, ihren Zusammenhang mit Migrationsprozessen und thematisiert die Verhandlung nationaler (und anderer) Identitäten on the move. Mit C. Michael Hall and Allan M. Williams plädiert der Text für das Konzept eines Mobilitätskontinuums, das die rechtlich-politische Kategorisierung und Gegenüberstellung verschiedener Mobilitätsformen zu problematisieren erlaubt. Darüber hinaus wird nach dem touristischen Moment in ganz unterschiedlichen Reiseformaten gefragt und eine stärkere Berücksichtigung der performativ-körperlichen Dimension von Mobilität gefordert.

description: Quantum electrodynamics in very strong Coulomb fields is one scope which has not yet been tested experimentally with suffcient accuracy to really determine whether the perturbative approach is valid. One sensitive test is the determination of the 1s Lamb Shift in highly-charged very heavy ions. The 1s Lamb Shift of hydrogen-like lead (Pb81+) and gold (Au78+) has been determined using the novel detector concept of silicon microcalorimeters for the detection of hard X-rays. The results of (260 +- 22) eV for lead and (208 +- 13) eV for gold are within error bars in good agreement with theoretical predictions. For hydrogen-like lead, this represents the most accurate determination of the 1s Lamb Shift to our knowledge.

description: Tourismus ist nicht (nur) eine gefällige und marktkonforme Darstellung von Land und Leuten, sondern erlaubt auch Einblicke in die Prozesse der nationalen und kulturellen Identitätskonstruktion. Basierend auf einem diskursiven Verständnis touristischer Narrative und Praktiken analysiere ich in diesem Artikel, wie zwei populäre österreichische Nachkriegsfilme, Der Hofrat Geiger (1952) und Echo der Berge / Der Förster vom Silberwald (1954), den touristischen Habitus als Voraussetzung für die Wiederrichtung einer österreichischen Heimat darstellen. Die physische und mentale Mobilität der „Touristen“ denen es gelingt, im Fremden jeweils auch das Eigene zu erkennen, wird dabei zum Modell für ein Nachkriegsösterreich, das sich seine Idee von Heimat als ein von Deutschland unabhängiges Konzept neu zusammenbauen muss. Anhand einer detaillierten Diskussion der Filme zeige ich, dass Tourismus nicht einfach ein Oberflächenphänomen ist, sondern nuancierte Einblicke in kulturelle und nationale Identitätskonstruktionen ermöglicht, die auch zu vergleichenden Studien mit anderen ‚belasteten’ Nationalidentitäten führen können.

description: Timeliness and contextual accuracy of recommendations are increasingly important when delivering contemporary digital marketing experiences. Conventional recommender systems (RS) suggest relevant but time-invariant items to users by accounting for their past purchases. These recommendations only map to customers' general preferences rather than a customer's specific needs immediately preceding a purchase. In contrast, RSs that consider the order of transactions, purchases, or experiences to measure evolving preferences can offer more salient and effective recommendations to customers: Sequential RSs not only benefit from a better behavioral understanding of a user's current needs but also better predictive power. In this paper, we demonstrate and rank the effectiveness of a sequential recommendation system by utilizing a production dataset of over 2.7 million credit card transactions for 46K cardholders. The method first employs an autoencoder on raw transaction data and submits observed transaction encodings to a GRU-based sequential model. The sequential model produces a MAP@1 metric of 47% on the out-of-sample test set, in line with existing research. We also discuss implications for embedding real-time predictions using the sequential RS into Nexus, a scalable, low-latency, event-based digital experience architecture.

‘Faux Touristes’?

description: Das Verhältnis von Migration und Tourismus ist hochambivalent. In Zeiten, in denen Migration von staatlicher Seite überwiegend restriktiv diskutiert und kontrolliert wird, erscheinen sie als gegensätzliche Repräsentationen von Mobilität: Weitgehend unreguliert für die, die reisen, um Geld auszugeben; stark begrenzt für jene, die sich auf den Weg machen, um Geld zu verdienen. Bei hohem Arbeitskräftebedarf verschieben sich dagegen die vermeintlich eindeutigen Zuschreibungen. Der Beitrag untersucht dieses Verhältnis in historischer Perspektive am Beispiel Frankreichs, der Schweiz und der Bundesrepublik Deutschland während der sechziger Jahre. Dabei wird deutlich, dass das Migrationsregime der ‚Gastarbeit’ eine weitaus größere Vielfalt an Mobilität kannte, als die einfache Dichotomie suggeriert. Migration und Tourismus sind in dieser Perspektive weit mehr als nur zwei rechtlich konstruierte Seiten der einen Medaille grenzüberschreitender Mobilität.

Quantum repeater based on cavity-QED evolutions and coherent light

Year: 2016

description: In the framework of cavity QED, we propose a quantum repeater scheme that uses coherent light and chains of atoms coupled to optical cavities. In contrast to conventional repeater schemes, we avoid the usage of two-qubit quantum logical gates by exploiting solely the cavity QED evolution. In our previous paper [D. Gonta and P. van Loock: Phys. Rev. A 88, 052308 (2013)], we already proposed a quantum repeater in which the entanglement between two neighboring repeater nodes was distributed using controlled displacements of input coherent light, while the produced low-fidelity entangled pairs were purified using ancillary (four-partite) entangled states. In this paper, the entanglement distribution is realized using a sequence of controlled phase shifts and displacements of input coherent light. Compared to previous coherent-state-based distribution schemes for two-qubit entanglement, the present scheme relies only upon a simple discrimination of two coherent states with opposite signs, which can be performed in a quantum mechanically optimal fashion via a beam splitter and two on-off detectors. The entanglement purification utilizes a scheme that avoids the usage of ancillary entangled resources. Our repeater scheme exhibits reasonable fidelities and repeater rates providing an attractive platform for long-distance quantum communication.

(Три года в Уссурийском крае) наблюдаются художественно специфичные воспроизводимые структуры фронтирного дискурса, связанные с мотивом преодоления дальневосточного пространства, репрезентированные в трех ракурсах: 1) мотивы преодоления пространства автором-повествователем; 2) мотивы преодоления пространства первопроходцами (или иными выдающимися историческими личностями); 3) мотивы преодоления пространства инокультурными персонажами.
description: : The article discusses the features of the plot and thematic representation of the motive for overcoming space as a characteristic typological feature of the frontier discourse about the Far East. The material for the study was the book of essays by the travel writer D. I. Schrader "Our Far East". (Three years in the Ussuri region). The aim of the study is to identify the plot and compositional features of the representation of the motif for overcoming space in the aspect of the frontier discourse about the Far East. As a result of the study, it was established that the motif for overcoming space in the Far Eastern frontier discourse is the most important text forming motif of the artistic image of the territory. In the book "Our Far East". (Three years in the Ussuri Territory) there are artistically specific reproducible structures of the frontier discourse associated with the motive of overcoming the Far Eastern space, represented in three perspectives: 1) motifs for overcoming space by the author-narrator; 2) motifs for overcoming space by pioneers (or other prominent historical figures); 3) motifs for overcoming space by characters from other cultures.

description: Dieser Artikel untersucht die Reisemuster von jungen Arbeitern und Studenten mit griechischem Migrationshintergrund, die während der 1960er und 70er Jahre in Westdeutschland gelebt haben. Basierend auf neueren Forschungsergebnissen, welche rigide Trennungslinien zwischen Migration und Tourismus in Frage stellen, wird hier die These vertreten, dass die Migrationserfahrungen von Griechen in Deutschland in Hinblick auf die beiden Phänomene weitaus komplexer waren als bisher angenommen. Während eine wachsende Anzahl deutscher Altersgenossen den Vergnügungstourismus für sich entdeckten, war das Reisen für junge Griechen zu diesem Zeitpunkt eher Mittel zum Zweck. Letztere benutzten Urlaube, um ihre Geburtsheimat zu besuchen und den Kontakt zur Familie aufrecht zu erhalten (oder zumindest wurde dies von ihnen erwartet). Jedoch fand in den frühen 1970er Jahren aufgrund des Influxes von griechischen Studenten an westdeutschen Universitäten eine Diversifizierung statt. Diese Gruppe wie auch einige junge Gastarbeiter fingen an, andere Länder zu erkunden und sich mit der Reisekultur von gleichaltrigen Westdeutschen – besonders dem Hitch-Hiking – vertraut zu machen. Der Artikel beleuchtet dabei kritisch die gängige These, dass der Jugendtourismus in der zweiten Hälfte des 20. Jahrhunderts dazu beitrug, eine transnationale europäische Identität zu schaffen. Tatsächlich nämlich entwickelten junge Migranten in den 1960er und 70er Jahren ihre Reiselust im Schatten eines kulturellen Nord-Süd Grabens.

description: Virtual sensing techniques have gained traction in applications to the structural health monitoring of monopile-based offshore wind turbines, as the strain response below the mudline, which is a primary indicator of fatigue damage accumulation, is impractical to measure directly with physical instrumentation. The Gaussian process latent force model (GPFLM) is a generalized Bayesian virtual sensing technique which combines a physics-driven model of the structure with a data-driven model of latent variables of the system to extrapolate unmeasured strain states. In the GPLFM, modeling of unknown sources of excitation as a Gaussian process (GP) serves to facilitate strain estimation by providing a complete stochastic characterization of the covariance relationship between input forces and states, using properties of the GP covariance kernel as well as correlation information supplied by the mechanical model. It is shown that posterior inference of the latent inputs and states is performed by Gaussian process regression of measured accelerations, computed efficiently using Kalman filtering and Rauch-Tung-Striebel smoothing in an augmented state-space model. While the GPLFM has been previously demonstrated in numerical studies to improve upon other virtual sensing techniques in terms of accuracy, robustness, and numerical stability, this work provides one of the first cases of in-situ validation of the GPLFM. The predicted strain response by the GPLFM is compared to subsoil strain data collected from an operating offshore wind turbine in the Westermeerwind Park in the Netherlands.

description: Tourismusforschung beinhaltet oft Auslandsstudien, aber ihre Ähnlichkeiten und Unterschiede im Vergleich zu kommerziellem Tourismus und ihre Interdependenzen mit den Themenfeldern Gender und Sexualität verdienen eine genauere Untersuchung und Analyse. Dieser Aufsatz beschäftigt sich zu Beginn mit zwei wichtigen Themen in der Forschung zur Geschichte des Tourismus, die hinsichtlich Auslandsstudien maßgeblich sind: erstens mit der Unterscheidung zwischen elitärem (oder „sachkundigem“) Reisen und Massentourismus, und zweitens mit der Annahme, dass Tourismus eine Flucht aus dem Alltag darstellt. Ausgehend von Briefen, Archivmaterialien und mündlichen Interviews hauptsächlich von amerikanischen Frauen, die in Frankreich studierten, bestätigt diese Forschungsarbeit die Arbeiten von Harvey Levenstein und John Urry, die Selbstfindung als den Hauptantriebsgrund für und die Hauptfolge von Jugendreisen einschließlich Auslandsstudien betonen. Sie stellt zudem fest, dass andere Faktoren des nationalen Vergleichs, Gender und das Verständnis des „Andersartigen“ diese Selbstfindung inhaltlich bestimmen und zusätzliche Wirkungen von Auslandsstudien darstellen.

description: We present and analyze a hybridizable discontinuous Galerkin (HDG) finite element method for the coupled Stokes--Biot problem. Of particular interest is that the discrete velocities and displacement are $H(\text{div})$-conforming and satisfy the compressibility equations pointwise on the elements. Furthermore, in the incompressible limit, the discretization is strongly conservative. We prove well-posedness of the discretization and, after combining the HDG method with backward Euler time stepping, present a priori error estimates that demonstrate that the method is free of volumetric locking. Numerical examples further demonstrate optimal rates of convergence in the $L^2$-norm for all unknowns and that the discretization is locking-free.

description: We investigate the growth of ion density perturbations in large-amplitude linear laser wakefields via two-dimensional particle-in-cell simulations. Growth rates and wave numbers are found to be consistent with a longitudinal strong-field modulational instability (SFMI). We examine the transverse dependence of the instability for a Gaussian wakefield envelope and show that growth rates and wavenumbers can be maximised off-axis. On-axis growth rates are found to decrease with increasing ion mass or electron temperature. These results are in close agreement with the dispersion relation of a Langmuir wave with energy density that is large compared to the plasma thermal energy density. The implications for wakefield accelerators, in particular multi-pulse schemes, are discussed.

description: We consider the problem of inferring an unknown number of clusters in replicated multinomial data. Under a model based clustering point of view, this task can be treated by estimating finite mixtures of multinomial distributions with or without covariates. Both Maximum Likelihood (ML) as well as Bayesian estimation are taken into account. Under a Maximum Likelihood approach, we provide an Expectation--Maximization (EM) algorithm which exploits a careful initialization procedure combined with a ridge--stabilized implementation of the Newton--Raphson method in the M--step. Under a Bayesian setup, a stochastic gradient Markov chain Monte Carlo (MCMC) algorithm embedded within a prior parallel tempering scheme is devised. The number of clusters is selected according to the Integrated Completed Likelihood criterion in the ML approach and estimating the number of non-empty components in overfitting mixture models in the Bayesian case. Our method is illustrated in simulated data and applied to two real datasets. An R package is available at https://github.com/mqbssppe/multinomialLogitMix.

description: Wireless sensor networks (WSNs) have attracted substantial research interest, especially in the context of performing monitoring and surveillance tasks. However, it is challenging to strike compelling trade-offs amongst the various conflicting optimization criteria, such as the network's energy dissipation, packet-loss rate, coverage and lifetime. This paper provides a tutorial and survey of recent research and development efforts addressing this issue by using the technique of multi-objective optimization (MOO). First, we provide an overview of the main optimization objectives used in WSNs. Then, we elaborate on various prevalent approaches conceived for MOO, such as the family of mathematical programming based scalarization methods, the family of heuristics/metaheuristics based optimization algorithms, and a variety of other advanced optimization techniques. Furthermore, we summarize a range of recent studies of MOO in the context of WSNs, which are intended to provide useful guidelines for researchers to understand the referenced literature. Finally, we discuss a range of open problems to be tackled by future research.

description: Forecasting the future states of surrounding traffic participants is a crucial capability for autonomous vehicles. The recently proposed occupancy flow field prediction introduces a scalable and effective representation to jointly predict surrounding agents' future motions in a scene. However, the challenging part is to model the underlying social interactions among traffic agents and the relations between occupancy and flow. Therefore, this paper proposes a novel Multi-modal Hierarchical Transformer network that fuses the vectorized (agent motion) and visual (scene flow, map, and occupancy) modalities and jointly predicts the flow and occupancy of the scene. Specifically, visual and vector features from sensory data are encoded through a multi-stage Transformer module and then a late-fusion Transformer module with temporal pixel-wise attention. Importantly, a flow-guided multi-head self-attention (FG-MSA) module is designed to better aggregate the information on occupancy and flow and model the mathematical relations between them. The proposed method is comprehensively validated on the Waymo Open Motion Dataset and compared against several state-of-the-art models. The results reveal that our model with much more compact architecture and data inputs than other methods can achieve comparable performance. We also demonstrate the effectiveness of incorporating vectorized agent motion features and the proposed FG-MSA module. Compared to the ablated model without the FG-MSA module, which won 2nd place in the 2022 Waymo Occupancy and Flow Prediction Challenge, the current model shows better separability for flow and occupancy and further performance improvements.
