description: We propose a relativistic particle model without Grassmann variables which, being canonically quantized, leads to the Dirac equation. Both $Γ$\,-matrices and the relativistic spin tensor are produced through the canonical quantization of the classical variables which parametrize the properly constructed relativistic spin surface. Although there is no mass-shell constraint in our model, our particle's speed cannot exceed the speed of light. The classical dynamics of the model is in correspondence with the dynamics of mean values of the corresponding operators in the Dirac theory. In particular, the position variable experiences {\it Zitterbewegung} in noninteracting theory. The classical equations for the spin tensor are the same as those of the Barut-Zanghi model of a spinning particle.

description: Driven by the landscape of garden-variety condensed matter systems, we have investigated how the dual spectral function behaves at the non-relativistic as well as relativistic fermionic fixed point by considering the probe Dirac fermion in an extremal charged dilatonic black hole with zero entropy. Although the pattern for both of the appearance of flat band and emergence of Fermi surface is qualitatively similar to that given by the probe fermion in the extremal Reissner-Nordstrom AdS black hole, we find a distinctly different low energy behavior around the Fermi surface, which can be traced back to the different near horizon geometry. In particular, with the peculiar near horizon geometry of our extremal charged dilatonic black hole, the low energy behavior exhibits the universal linear dispersion relation and scaling property, where the former indicates that the dual liquid is a Fermi one while the latter implies that the dual liquid is not exactly of Landau Fermi type.

description: Zur Realisierung von Regelungssystemen zur Stabilisierung von Kraftfahrzeugen in kritischen Fahrsituationen ist die Ermittlung verschiedener Regelgrößen und Parameter, beispielsweise des Reifenschlupfs oder des Kraftschlussbeiwerts zwischen Reifen und Fahrbahn, erforderlich. Aufgrund messtechnischer Beschränkungen oder zur Kostenersparnis werden dabei häufig reale Sensoren durch Zustandsschätzer oder -beobachter ersetzt. Ausgehend von der Definition funktionaler Anforderungen wird im Rahmen dieser Arbeit ein solcher Zustands- und Parameterschätzer für fahrdynamische Größen entwickelt und validiert. Dieser ist in der Lage, sich mittels eines adaptiven Reifenmodells automatisch an unterschiedliche Fahrbahnbedingungen anzupassen. Bei der Entwicklung und Validierung werden modell- und optimierungsbasierte Methoden genutzt. Im Rahmen einer Model-in-the-Loop-Simulation werden zunächst anhand eines virtuellen Referenzfahrzeugs die Vorentwicklung sowie eine erste Validierung mitsamt einer Untersuchung der Robustheit bezüglich unmodellierter Störgrößen durchgeführt. Anschließend erfolgt die Übertragung des Ansatzes auf ein reales Fahrzeug, wobei dort die Implementierung auf einem Rapid-Control-Prototyping-Steuergerät sowie eine Hardware-in-the-Loop Simulation mit realen Versuchsdaten erfolgen. Zuletzt wird der Zustands- und Parameterschätzer als Anwendungsbeispiel zusammen mit einer Reifenlängsschlupfregelung unter Verwendung einer weiteren Model-in-the-Loop-Simulation validiert.
description: The realization of control systems for the stabilization of motor vehicles in critical driving situations requires the determination of various control variables and parameters, for example, of tire slip or the coefficient of adhesion between tire and road. Due to measurement restrictions or to save costs, real sensors are often replaced by state estimators or observers. Based on the definition of functional requirements, such a state and parameter estimator for vehicle dynamics is developed and validated within the scope of this thesis. This estimator is able to automatically adapt to different road conditions by means of an adaptive tire model. Model- and optimization-based methods are used for development and validation. Utilizing a Model-in-the-Loop simulation, the pre-development and a first validation including an investigation of the robustness with regard to unmodelled disturbance variables are carried out using a virtual reference vehicle. The approach is then transferred to a real vehicle, where it is implemented on a rapid control prototyping ECU and a Hardware-in-the-Loop simulation with real test data. Finally, the state and parameter estimator is validated as an application example together with a tire slip control within the scope of another Model-in-the-Loop simulation.

description: We introduce the heat method for computing the shortest geodesic distance to a specified subset (e.g., point or curve) of a given domain. The heat method is robust, efficient, and simple to implement since it is based on solving a pair of standard linear elliptic problems. The method represents a significant breakthrough in the practical computation of distance on a wide variety of geometric domains, since the resulting linear systems can be prefactored once and subsequently solved in near-linear time. In practice, distance can be updated via the heat method an order of magnitude faster than with state-of-the-art methods while maintaining a comparable level of accuracy. We provide numerical evidence that the method converges to the exact geodesic distance in the limit of refinement; we also explore smoothed approximations of distance suitable for applications where more regularity is required.

description: We present our recent work on query-focused summarization, focusing on our efforts in building and applying models of rhetorical-semantic relations (RSRs) such as contrast and causality. We overview ongoing work in extracting and evaluating RSR models. We describe our system for query-focused summarization, focusing on an enhanced, feature-based framework. We present results of experiments to measure the impact of both RSR and other features on selection and ordering of summary content. We conclude with an overview of results from the official DUC06 evaluation.

description: We study fundamental optical gap solitons in the model of a fiber Bragg grating (BG), which is subjected to a periodic modulation of the local reflectivity, giving rise to a supergrating. In addition, the local refractive index is also periodically modulated with the same period. It is known that the supergrating opens an infinite system of new bandgaps in the BG's spectrum. We use a combination of analytical and computational methods to show that each emerging bandgap is filled with gap solitons (GSs), including asymmetric ones and bound states of the GSs. In particular, bifurcations of the GSs created by the supergrating are studied in terms of a geometric analysis.

description: In this work we study a modified Susceptible-Infected-Susceptible (SIS) model in which the infection rate $λ$ decays exponentially with the number of reinfections $n$, saturating after $n=l$. We find a critical decaying rate $ε_{c}(l)$ above which a finite fraction of the population becomes permanently infected. From the mean-field solution and computer simulations on hypercubic lattices we find evidences that the upper critical dimension is 6 like in the SIR model, which can be mapped in ordinary percolation.

Consistent 3D Quantum Gravity on Lens Spaces

description: We study non-perturbative quantization of 3d gravity with positive cosmological constant (de Sitter space being the prototype vacuum solution, whose Euclideanization of course gives the three sphere) on the background topology of lens space, which is a three spheres modulo a discrete group. Instead of the strategy followed by a recent work \cite{Castro:2011xb}, which compares results in the second and first order formulations of gravity, we concentrate on the later solely. We note, as a striking feature, that the quantization, that relies heavily on the axiomatics of topological quantum field theory (TQFT) can only be consistently carried by augmenting the conventional theory by an additional topological term coupled through a dimensionless parameter. More importantly the introduction of this additional parameter renders the theory finite.

Performance of Variable Stiffness Structures Under Compressive Force
Creators: name: Harris, Maya
Publisher: name: Stanford Digital Repository
Year: 2023
Subjects: subject: Composite materials
subject: Metamaterials
subject: Variable stiffness
subject: Aerospace engineering

description: With currently available materials, designers of lightweight deployable and adaptable
spacecraft are forced to make a choice. Because most available materials have fixed mechanical
properties, designers can either optimize their structures for flexibility and the ability to change
shape, or they can prioritize their ability to withstand high loads. To combat this problem and
pave the way for future space technologies, materials are being developed with variable
mechanical properties. These materials allow for on-demand control of properties like bending
stiffness, enabling structures to continually adapt to their environments. As part of this effort, the
Stanford Reconfigurable & Active Structures Lab has been developing variable stiffness hinges
made of fiber reinforced polymer and silicone dry adhesive layers. These hinges can switch
between a bonded (stiff) and debonded (soft) state on command. And, when they are integrated
into a larger structure, the hinges will enable the structure to also switch between states. Having
multiple hinges in the same structure will yield even more distinct stiffness states. The goal of
this project is twofold. First, to better understand and characterize the behavior of the hinges by
creating software that can analyze their shape and their performance during experimental testing. Second, to integrate multiple hinges into different structures in order to determine the best configuration for controlling the hinges and yielding different stiffness states. To meet the first goal, MATLAB code was developed that could track the shape of a hinge throughout a testing
video. A new test setup process was also developed to yield videos that were most compatible
with the software. The MATLAB analysis revealed several differences in performance between
the experimental and simulated hinges, suggesting that further work needs to be done on building more consistent and resilient hinges and on improving the simulation model. To meet the second goal, many different geometries were explored and several different structures were tested under compressive force on a universal testing machine. Different problems with each of these structures manifested during testing, and in the end, only a structure containing a single hinge showed promising results. The primary conclusion is that these hinges do not perform reliably under compressive force and that a different approach to hinge integration is needed in the future.
A Skip-Chain Conditional Random Field for Ranking Meeting Utterances by Importance

description: We describe a probabilistic approach to content selection for meeting summarization. We use skipchain Conditional Random Fields (CRF) to model non-local pragmatic dependencies between paired utterances such as Question-Answer that typically appear together in summaries, and show that these models outperform linear-chain CRFs and Bayesian models in the task. We also discuss different approaches for ranking all utterances in a sequence using CRFs. Our best performing system achieves 91.3% of human performance when evaluated with the Pyramid evaluation metric, which represents a 3.9% absolute increase compared to our most competitive non-sequential classifier.

description: Das RNA-bindende Protein (RBP) Musashi1 (MSI1) ist ein postulierter Regulator der mRNA Translation verschiedener Zieltranskripte, wodurch es die Progression des Zellzyklus fördert. Das MSI1 Protein zeigt eine erhöhte Expression während der Embryogenese in Stammzellen, wo es die Fähigkeit der Selbsterneuerung der Stammzellen unterstützt und deren Differenzierungsprozess inhibiert. Das MSI1 Protein zeigt eine Re-Expression in verschiedenen Krebsarten, u.a. im Gehirntumor Glioblastom (GBM). Die hier vorliegende Studie identifiziert MSI1 als Regulator der stammzellartigen Eigenschaften des GBM und hebt die Kontrolle der mRNA Stabilität als neue Funktion für MSI1 hervor. Ebenso stellt die Arbeit Argumente für potentielle MSI1-abhängige Behandlungsoptionen für GBM bereit. Des Weiteren wurde eine bisher unentdeckte MSI1 Isoform beschrieben und charakterisiert.
description: The RNA-binding protein (RBP) Musashi (MSI1) is reported to control the mRNA translation of various target transcripts to promote cell cycle progression. It is highly abundant during embryogenesis in stem cells, where it was found to support stem cell self-renewal and to inhibit differentiation. MSI1 is upregulated in various cancers, with the highest expression in Glioblastoma (GBM), where it is presumed to promote an aggressive stemness-like tumor cell phenotype. The here presented data identify MSI1 as regulator of stemness in GBM and spots mRNA stability control as a new function for the well described translational modulator. The study provides rationales for potential treatment options for GBM. In addition to the presented data, an so far undescribed functional MSI1 protein isoform, resulting from alternative splicing, was identified. GBM samples as well as primary GBM-CSC also revealed the expression of this unknown MSI1 isoform.

description: Wilkinson and Pickett consider the income distribution in 23 rich countries (U.S. included) and plot the ratio between the income received by the top 20% of the population to that received by the bottom 20% - as a measure of inequality - against the Index of health and social problems built on the UN Development Program data (averaged for the reporting period 2003-2006) for the same countries. This index - like the well known Human Development Index (HDI) - is a simple average of the data for the following social phenomenon: level of trust, mental illness (no data for Denmark), life expectancy, infant mortality, obesity, children educational performance (no data for UK), teenage birth, homicides, imprisonment rates, social mobility. Without entering into the details, the main and robust message coming out from the book is that among the 23 rich countries the more unequal ones do worse according to almost every quality of life indicator. The U.S. - the most unequal country in the sample - is the most striking example of that, followed by Portugal and the UK (both places where the gap between rich and poor is relatively large), whilst the Scandinavian countries invariably rank last. The message is clear: social problems were caused by material life conditions the more affluent countries should have performed better than the less affluent (still in the same basket of rich countries). Instead, the evidence suggests that it is the relative position within a society to matter the most: where income differences are bigger, social distances are bigger and social stratification more remarkable.

description: We determine the velocity vector of M31 with respect to the Milky Way and use this to constrain the mass of the Local Group, based on HST proper-motion measurements presented in Paper I. We construct N-body models for M31 to correct the measurements for the contributions from stellar motions internal to M31. We also estimate the center-of-mass motion independently, using the kinematics of satellite galaxies of M31 and the Local Group. All estimates are mutually consistent, and imply a weighted average M31 heliocentric transverse velocity of (v_W,v_N) = (-125.2+/-30.8, -73.8+/-28.4) km/s. We correct for the reflex motion of the Sun using the most recent insights into the solar motion within the Milky Way. This implies a radial velocity of M31 with respect to the Milky Way of V_rad = -109.3+/-4.4 km/s, and a tangential velocity V_tan = 17.0 km/s (<34.3 km/s at 1-sigma confidence). Hence, the velocity vector of M31 is statistically consistent with a radial (head-on collision) orbit towards the Milky Way. We revise prior estimates for the Local Group timing mass, including corrections for cosmic bias and scatter. Bayesian combination with other mass estimates yields M_LG = M_MW(vir) + M_M31(vir) = (3.17 +/- 0.57) x 10^12 solar masses. The velocity and mass results imply at 95% confidence that M33 is bound to M31, consistent with expectation from observed tidal deformations. (Abridged)

description: Online handwriting recognition of Arabic script is a difficult problem since it is naturally both cursive and unconstrained. The analysis of Arabic script is further complicated in comparison to Latin script due to obligatory dots/stokes that are placed above or below most letters. This paper introduces a Hidden Markov Model (HMM) based system to provide solutions for most of the difficulties inherent in recognizing Arabic script including: letter connectivity, position-dependent letter shaping, and delayed strokes. This is the first HMM-based solution to online Arabic handwriting recognition. We report successful results for writer-dependent and writer-independent word recognition.

description: The Arabic language is a collection of spoken dialects with important phonological, morphological, lexical, and syntactic differences, along with a standard written language, Modern Standard Arabic (MSA). Since the spoken dialects are not officially written, it is very costly to obtain adequate corpora to use for training dialect NLP tools such as parsers. In this paper, we address the problem of parsing transcribed spoken Levantine Arabic (LA). We do not assume the existence of any annotated LA corpus (except for development and testing), nor of a parallel corpus LA-MSA. Instead, we use explicit knowledge about the relation between LA and MSA.

description: Im Betrachtungszeitraum 2011 wurden in der Klinik für Innere Medizin II am Universitätsklinikum Halle alle Patienten mit Nachweis resistenter Erreger erfasst. In einer retrospektiven Fall-Kontroll- Studie wurden diese in Bezug auf die Verweildauer, diagnostischen Aufwand, Antibiotikatherapie und Behandlungsergebnis untersucht und mit einer entsprechenden Kontrollgruppe verglichen. Die Untersuchungen haben gezeigt, dass Patienten mit Nachweis resistenter Erreger im Median vier Tage länger stationär behandelt wurden und im Median eine diagnostische Untersuchung mehr durchgeführt wurde. Die Anzahl verordneter Antibiotika war in der Fallgruppe statistisch signifikant höher als in der Kontrollgruppe. Ebenso erbrachte der Nachweis resistenter Erreger die Tendenz einer gesteigerten Mortalität. Diesen Ergebnissen gilt es Aufmerksamkeit zu schenken und zukünftig Strategien zur Verbesserung der Patientenversorgung zu entwickeln.
description: In 2011 patients hospitalized at the clinic of Internal Medicine II at the University of Halle with proof of resistant pathogens underwent examination. In a retrospective case-control analysis, they were compared with non-resistant pathogen control groups in regard to length of stay, diagnostic effort, antibiotic therapy and treatment outcome. The investigations have shown that patients with proof of resistant pathogens were treated in hospital for a median of four days longer and had in the median one more diagnostic examination. The number of antibiotics prescribed was statistically significantly higher in the case group than in the control group. The detection of resistant pathogens also showed a tendency to increased mortality. It is important to pay attention to these results and to develop strategies to improve patient care in the future.

description: This paper offers an approach and a theoretical framework for eliciting emotional speech using actors. The framework is developed by connecting the goal-based model of emotion proposed by Abelson [1], the work of appraisal theorists, and an approach to the actor's technical process widely used in the professional theater and taught in modern conservatories. In doing so, we hope to address some of the difficulties currently encountered in the use of acted speech in emotion research.

description: Production data from the Los Humeros geothermal field in Mexico are used to develop a forecast method for operation of the field in the future. This method supports understanding the limitations of sustainably exploiting a geothermal reservoir. Using such forecasts, fluid extraction could be scheduled in order to fulfill the steam demand of the installed capacity. Moreover, the forecast of the extraction can diminish the commercial risk involved and therefore clear the way for new investments. Herein, we determined the total extracted heat from the Los Humeros geothermal system, with the aim to forecast the next phase of fluid extraction. We took the information from 29 producing wells to analyze their historic geothermal fluid production. From their statistical distribution of data, we estimated the amount of extracted fluids for a future phase. The size of the heat reserve previous to exploitation was calculated from the forecasted and the extracted heat. Thus, the recovery factor of the system was calculated as the ratio of the accumulated production of heat and the initial heat in place. The general recovery factor for 60 years of production was calculated as 37–44%. Due to the heterogeneity of the system, this study conducted individual assessments. The forecasted heat extraction for the next 30 years of production, amounts to 580 PJ assuming a constant extraction rate between 6 and 56 ton·[h]−1 depending on the particular well. The results of this study potentially complement the existing models of the geothermal exploitation and offer an estimation of the future production of the Los Humeros, which could be a good basis for decision-making and management of the site.

Both the leading color-singlet and color-octet channels are included. For the $h_c$ production associated with light hadrons, the total production rate is dominated by the color-octet channel, thus the future measurement of this process may impose useful constraint on the value of the color-octet matrix element $$; for the $h_c$ production associated with charmed hadrons, the total production rate is about one order of magnitude smaller, and dominated by the color-singlet channel.

description: The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO) mission carries magnetometers that are dedicated to enhance the satellite’s navigation. After appropriate calibration and characterisation of artificial magnetic disturbances, these observations are valuable assets to characterise the natural variability of Earth’s magnetic field. We describe the data pre-processing, the calibration, and characterisation strategy against a high-precision magnetic field model applied to the GRACE-FO magnetic data. During times of geomagnetic quiet conditions, the mean residual to the magnetic model is around 1 nT with standard deviations below 10 nT. The mean difference to data of ESA’s Swarm mission, which is dedicated to monitor the Earth’s magnetic field, is mainly within ± 10 nT during conjunctions. The performance of GRACE-FO magnetic data is further discussed on selected scientific examples. During a magnetic storm event in August 2018, GRACE-FO reveals the local time dependence of the magnetospheric ring current signature, which is in good agreement with results from a network of ground magnetic observations. Also, derived field-aligned currents (FACs) are applied to monitor auroral FACs that compare well in amplitude and statistical behaviour for local time, hemisphere, and solar wind conditions to approved earlier findings from other missions including Swarm. On a case event, it is demonstrated that the dual-satellite constellation of GRACE-FO is most suitable to derive the persistence of auroral FACs with scale lengths of 180 km or longer. Due to a relatively larger noise level compared to dedicated magnetic missions, GRACE-FO is especially suitable for high-amplitude event studies. However, GRACE-FO is also sensitive to ionospheric signatures even below the noise level within statistical approaches. The combination with data of dedicated magnetic field missions and other missions carrying non-dedicated magnetometers greatly enhances related scientific perspectives.

description: We devise a platform for noise-resistant quantum computing using the valley degree of freedom of Si quantum dots. The qubit is encoded in two polarized (1,1) spin-triplet states with different valley compositions in a double quantum dot, with a Zeeman field enabling unambiguous initialization. A top gate gives a difference in the valley splitting between the dots, allowing controllable interdot tunneling between opposite valley eigenstates, which enables one-qubit rotations. Two-qubit operations rely on a stripline resonator, and readout on charge sensing. Sensitivity to charge and spin fluctuations is determined by intervalley processes and is greatly reduced as compared to conventional spin and charge qubits. We describe a valley echo for further noise suppression.

description: Previous studies of human performance in deception detection have found that humans generally are quite poor at this task, comparing unfavorably even to the performance of automated procedures. However, different scenarios and speakers may be harder or easier to judge. In this paper we compare human to machine performance detecting deception on a single corpus, the Columbia-SRI-Colorado Corpus of deceptive speech. On average, our human judges scored worse than chance — and worse than current best machine learning performance on this corpus. However, not all judges scored poorly. Based on personality tests given before the task, we find that several personality factors appear to correlate with the ability of a judge to detect deception in speech. Index Terms: deception, deceptive, perception, personality.

H2CO in the Horsehead PDR: Photo-desorption of dust grain ice mantles

description: Aims: For the first time we investigate the role of the grain surface chemistry in the Horsehead Photo-dissociation region (PDR). Methods: We performed deep observations of several H2CO rotational lines toward the PDR and its associated dense-core in the Horsehead nebula, where the dust is cold ($\Td \simeq 20-30$ K). We complemented these observations with a map of the p-H2CO $~3_{03}-2_{02}$ line at 218.2 GHz (with 12" angular resolution). We determine the H2CO abundances using a detailed radiative transfer analysis and compare these results with PDR models that include either pure gas-phase chemistry or both gas-phase and grain surface chemistry. Results: The H2CO abundances ($\simeq 2-3 \times 10^{-10}$) with respect to H-nuclei are similar in the PDR and dense-core. In the dense-core the pure gas-phase chemistry model reproduces the observed H2CO abundance. Thus, surface processes do not contribute significantly to the gas-phase H2CO abundance in the core. In contrast, the formation of H2CO on the surface of dust grains and subsequent photo-desorption into the gas-phase are needed in the PDR to explain the observed gas-phase H2CO abundance, because the gas-phase chemistry alone does not produce enough H2CO. The assignments of different formation routes are strengthen by the different measured ortho-to-para ratio of H2CO: the dense-core displays the equilibrium value ($\sim3$) while the PDR displays an out-of-equilibrium value ($\sim2$). Conclusions: Photo-desorption of H2CO ices is an efficient mechanism to release a significant amount of gas-phase H2CO into the Horsehead PDR.

description: We study the exchange and correlation hole of the valence shell of second row atoms using variational Monte Carlo techniques, especially correlated estimates, and norm-conserving pseudopotentials. The well-known scaling of the valence shell provides a tool to probe the behavior of exchange and correlation as a functional of the density and thus test models of density functional theory. The exchange hole shows an interesting competition between two scaling forms -- one caused by self-interaction and another that is approximately invariant under particle number, related to the known invariance of exchange under uniform scaling to high density and constant particle number. The correlation hole shows a scaling trend that is marked by the finite size of the atom relative to the radius of the hole. Both trends are well captured in the main by the Perdew-Burke-Ernzerhof generalized-gradient approximation model for the exchange-correlation hole and energy.

description: Der demographische Wandel und die steigende Lebenserwartung führen zu einem Anteil älterer Menschen in der Bevölkerung. Physiologische und pathologische Abbauprozesse im Alter gehen u.a. mit einer Reduktion des Gleichgewichts, Gangbildveränderungen sowie mit einer Abnahme der kognitiven Leistungsfähigkeit einher. Diese negativen Entwicklungen können zu einer erhöhten Sturzgefahr mit zum Teil dramatischem Ausgang für die Betroffenen führen. Der Gang älterer Menschen zeichnet sich durch eine reduzierte Gehgeschwindigkeit, eine verkürzte Schrittlänge und einer Zunahme der Doppelbeinstandphase aus, während die Kadenz bis ins hohe Alter unverändert bleibt. Die Gehgeschwindigkeit kann zur Beurteilung der Gangleistung herangezogen werden, da sie ab einem Alter von 63 Jahren kontinuierlich sinkt. Zudem gibt auch die Variabilität des Gangs gute Hinweise auf pathologische Gangmuster. Eine veränderte Variabilität des Gangs wird in der Literatur als ein „Frühsymptom“ einer Ganginstabilität gesehen. Besonders deutlich zeigt sich die Abnahme der körperlichen und geistigen Leistungsfähigkeit im Alter, wenn neben einer einzelnen Aufgabe, wie dem Gehen, noch eine zweite Aufgabe simultan bewältigt werden muss (dual-task). Die Zweitaufgabe kann sowohl motorischer als auch kognitiver Natur sein. Unter dual-task-Bedingungen kommt es bei auch gesunden älteren Menschen zu einer Steigerung der Variabilität des Gangs und zu einer Zunahme der Sturzgefahr. Aufgrund altersbedingter Abnahmen der visuellen, propriozeptiven und vestibulären Leistung sowie der Reduktion der grauen und weißen Substanz des zentralen Nervensystems kommt es zudem im Alter zu einer Abnahme der statischen und dynamischen Gleichgewichtsleistung. Obwohl das Risiko für einen Sturz multifaktoriell beeinflusst wird, wurde bereits in zahlreichen Studien mittels sportlichen und/oder kognitiven Interventionen versucht, die dual-task-Leistung im Alter sowie die Gleichgewichtsleistung zu steigern, um das Sturzrisiko zu reduzieren. Dazu wurden vor allem Sportarten verwendet, die ein komplexes Anforderungsprofil aufwiesen und aus einer Kombination von Kraft-, Ausdauer- und Gleichgewichtsanteilen bestanden. Beispiele sind das Tanzen oder das Tai-Chi, das zu den asiatischen Kampfsportarten gehört. Auch andere Stilrichtungen der „Martial Arts“, wie das Taekwondo oder das Kung Fu, wurden bereits hinsichtlich 2 ihres Nutzens zur Verbesserung des Gleichgewichts und der Gangleistung unter single- und dual-task-Bedingungen untersucht. Bislang unbekannt ist der Nutzen der hierzulande populärsten Kampfkunst, des Karate. Karate ist den bereits untersuchten Kampfsportarten (z.B. Tai-Chi) ähnlich und könnte daher als Intervention durchaus geeignet sein.

description: Photonic integrated circuits (PIC) become increasingly important for numerous applications. Mass production of PIC has become widely available, but large-volume low-cost photonic packaging still represents a challenge. Additive micro-fabrication of free-form optical coupling structures is discussed as a concept to overcome this technology gap. Multi-photon 3D-lithography is used to fabricate dielectric waveguides ("photonic wire bonds", PWB) as well as facet-attached microlenses (FaML).

description: Recently, many Natural Language Processing (NLP) applications have improved the quality of their output by using various machine learning techniques to mine Information Extraction (IE) patterns for capturing information from the input text. Currently, to mine IE patterns one should know in advance the type of the information that should be captured by these patterns. In this work we propose a novel methodology for corpus analysis based on cross-examination of several document collections representing different instances of the same domain. We show that this methodology can be used for automatic domain template creation. As the problem of automatic domain template creation is rather new, there is no well-defined procedure for the evaluation of the domain template quality. Thus, we propose a methodology for identifying what information should be present in the template. Using this information we evaluate the automatically created domain templates through the text snippets retrieved according to the created templates.
