description: A smaller amount of ankle-dorsiflexion displacement during landing is associated with less knee-flexion displacement and greater ground reaction forces, and greater ground reaction forces are associated with greater knee-valgus displacement. Additionally, restricted dorsiflexion range of motion (ROM) is associated with greater knee-valgus displacement during landing and squatting tasks. Because large ground reaction forces and valgus displacement and limited knee-flexion displacement during landing are anterior cruciate ligament (ACL) injury risk factors, dorsiflexion ROM restrictions may be associated with a greater risk of ACL injury. However, it is unclear whether clinical measures of dorsiflexion ROM are associated with landing biomechanics.

description: Το τελευταίο χρονικό διάστημα παρατηρείται αύξηση ενδιαφέροντος σχετικά με την ανάπτυξη βιώσιμων λύσεων όπως οι ανανεώσιμες πηγές ενέργειας (ΑΠΕ), η διεσπαρμένη παραγωγή ηλεκτρικής ενέργειας, τα συστήματα αποθήκευσης ενέργειας και τα ηλεκτρικά οχήματα (electric vehicles - EVs). Στις προηγούμενες εφαρμογές, γίνεται χρήση πολλών DC/DC και DC/AC μετατροπέων ισχύος. Ωστόσο, τα προαναφερθέντα συστήματα μετατροπής ισχύος αντιμετωπίζουν αρκετές προκλήσεις, συμπεριλαμβανομένου του συνολικού κόστους, του μεγέθους και της πολυπλοκότητας του συνολικού συστήματος. Στην παρούσα μεταπτυχιακή εργασία, αναπτύχθηκαν δύο μη-απομονωμένοι μετατροπείς πολλαπλών θυρών (MPC), που ενσωματώνουν τέσσερις DC πηγές και μια AC έξοδο, ο καθένας. Το βασικό τους πλεονέκτημα είναι ότι αποτελούνται από μικρότερο αριθμό ηλεκτρονικών εξαρτημάτων σε σύγκριση με τη χρησιμοποίηση ξεχωριστών μετατροπέων για κάθε θύρα. Χαρακτηρίζονται από το ότι περιλαμβάνουν μικρότερο συνολικό αριθμό πηνίων και πυκνωτών, αλλά και από την χρησιμοποίηση τριών διακοπτών που λειτουργούν σε χαμηλή διακοπτική συχνότητα συγκριτικά με άλλους μετατροπείς της βιβλιογραφίας με τον ίδιο αριθμό θυρών, οι οποίοι αποτελούνται μόνο από διακόπτες υψηλής διακοπτικής συχνότητας. Τα προτεινόμενα κυκλώματα έχουν σχεδιαστεί για τη διαχείριση ισχύος ενός υβριδικού ενεργειακού συστήματος, το οποίο αποτελείται από μία συστοιχία φωτοβολταϊκών πλαισίων (PV), μία συστοιχία μπαταριών, μία συστοιχία υπερπυκνωτών (SC), την μπαταρία ενός EV, καθώς και διασύνδεση με το ηλεκτρικό δίκτυο. Παρόλο που η φωτοβολταϊκή συστοιχία είναι απευθείας συνδεδεμένη στο DC-link, ο αλγόριθμος ανίχνευσης του σημείου μέγιστης ισχύος (MPPT) δύναται να εφαρμοστεί δίχως κάποιον επιπλέον μετατροπέα ισχύος, μειώνοντας έτσι τον συνολικό αριθμό ηλεκτρονικών εξαρτημάτων. Οι προτεινόμενες τοπολογίες, επιπρόσθετα, ενσωματώνουν μια τριφασική έκδοση ενός split-source αντιστροφέα (SSI), με σκοπό την περαιτέρω μείωση των απωλειών ισχύος στους ημιαγωγικούς διακόπτες. Επίσης, ο μετατροπέας SSI των MPCs έχει τροποποιηθεί για να υποστηρίζεται η αμφίδρομη ροή ισχύος. Τέλος, αναπτύχθηκαν τα εργαστηριακά πρωτότυπα των δύο αρχιτεκτονικών και η ορθή λειτουργία τους επικυρώθηκε υπό διάφορες συνθήκες λειτουργίας.

description: Speaker embeddings represent a means to extract representative vectorial representations from a speech signal such that the representation pertains to the speaker identity alone. The embeddings are commonly used to classify and discriminate between different speakers. However, there is no objective measure to evaluate the ability of a speaker embedding to disentangle the speaker identity from the other speech characteristics. This means that the embeddings are far from ideal, highly dependent on the training corpus and still include a degree of residual information pertaining to factors such as linguistic content, recording conditions or speaking style of the utterance. This paper introduces an analysis over six sets of speaker embeddings extracted with some of the most recent and high-performing DNN architectures, and in particular, the degree to which they are able to truly disentangle the speaker identity from the speech signal. To correctly evaluate the architectures, a large multi-speaker parallel speech dataset is used. The dataset includes 46 speakers uttering the same set of prompts, recorded in either a professional studio or their home environments. The analysis looks into the intra- and inter-speaker similarity measures computed over the different embedding sets, as well as if simple classification and regression methods are able to extract several residual information factors from the speaker embeddings. The results show that the discriminative power of the analyzed embeddings is very high, yet across all the analyzed architectures, residual information is still present in the representations in the form of a high correlation to the recording conditions, linguistic contents and utterance duration.

description: Sharing spectrum with incumbents such as radar systems is an attractive solution for cellular operators in order to meet the ever growing bandwidth requirements and ease the spectrum crunch problem. In order to realize efficient spectrum sharing, interference mitigation techniques are required. In this letter we address techniques to mitigate MIMO radar interference at MIMO cellular base stations (BSs). We specifically look at the amount of power received at BSs when radar uses null space projection (NSP)-based interference mitigation method. NSP reduces the amount of projected power at targets that are in-close vicinity to BSs. We study this issue and show that this can be avoided if radar employs a larger transmit array. In addition, we compute the coherence time of channel between radar and BSs and show that the coherence time of channel is much larger than the pulse repetition interval of radars. Therefore, NSP-based interference mitigation techniques which depends on accurate channel state information (CSI) can be effective as the problem of CSI being outdated does not occur for most practical scenarios.

Inclination-Induced Polarization of Scattered Millimeter Radiation from Protoplanetary Disks: The Case of HL Tau

description: Spatially resolved polarized millimeter/submillimeter emission has been observed in the disk of HL Tau and two other young stellar objects. It is usually interpreted as coming from magnetically aligned grains, but can also be produced by dust scattering, as demonstrated explicitly by Kataoka et al. for face-on disks. We extend their work by including the polarization induced by disk inclination with respect to the line of sight. Using a physically motivated, semi-analytic model, we show that the polarization fraction of the scattered light increases with the inclination angle $i$, reaching $1/3$ for edge-on disks. The inclination-induced polarization can easily dominate that intrinsic to the disk in the face-on view. It provides a natural explanation for the two main features of the polarization pattern observed in the tilted disk of HL Tau ($i \sim 45^\circ$): the polarized intensity concentrating in a region elongated more or less along the major axis, and polarization in this region roughly parallel to the minor axis. This broad agreement provides support to dust scattering as a viable mechanism for producing, at least in part, polarized millimeter radiation. In order to produce polarization at the observed level ($\sim 1\%$), the scattering grains must have grown to a maximum size of tens of microns. However, such grains may be too small to produce the opacity spectral index of $β\lesssim 1$ observed in HL Tau and other sources; another population of larger, millimeter/centimeter-sized, grains may be needed to explain the bulk of the unpolarized continuum emission.

description: In a world of increasing globalisation, Neurosurgeons need to be able to diagnose and treat neurosurgical conditions which may not be common to the local population. To illustrate this, we describe the case of an intracranial tuberculoma presenting in the post-partum period. Tuberculosis (TB) is a widely recognised mimic of other conditions, including high grade gliomas, which can result in diagnostic delays. We highlight clinical features that should increase the index of suspicion for TB and create a low threshold for trial of empirical treatment. We also discuss educational partnership strategies that may help facilitate global perspectives in neurosurgical training.

description: The general problem of effectively using interactive engagement in non-introductory physics courses remains open. We present a three-year study comparing different approaches to lecturing in an intermediate mechanics course at the Colorado School of Mines. In the first year, the lectures were fairly traditional. In the second year the lectures were modified to include Socratic dialogs between the instructor and students. In the third year, the instructor used a personal response system and Peer Instruction-like pedagogy. All other course materials were nearly identical to an established traditional lecture course. We present results from a new instructor-constructed conceptual survey, exams, and course evaluations. We observe little change in student exam performance as lecture techniques varied, though students consistently stated clickers were "the best part of the course" from which they "learned the most." Indeed, when using clickers in this course, students were considerably more likely to become engaged than students in CSM introductory courses using the same methods.

description: It has been argued recently that string theory effects qualitatively modify the effective black hole geometry experienced by modes with radial momentum of order $1/\sqrt{α'}$. At tree level, these $α'$-effects can be explicitly worked out in two-dimensional string theory, and have a natural explanation in the T-dual description as coming from the integration of the zero-mode of the linear dilaton, what yields a contribution that affects the scattering phase-shift in a peculiar manner. It has also been argued that the phase-shift modification has its origin in a region of the moduli space that does not belong to the exterior black hole geometry, leading to the conclusion that at high energy the physics of the problem is better described by the dual model. Here, we elaborate on this argument. We consider the contribution of worldsheet instantons in the 2D Euclidean black hole sigma-model and study its influence on the phase-shift at high energy.

description: It is a well-known fact that feedback does not increase the capacity of point-to-point memoryless channels, however, its effect in secure communications is not fully understood yet. In this work, an achievable scheme for the wiretap channel with generalized feedback is presented. This scheme, which uses the feedback signal to generate a shared secret key between the legitimate users, encrypts the message to be sent at the bit level. New capacity results for a class of channels are provided, as well as some new insights into the secret key agreement problem. Moreover, this scheme recovers previously reported rate regions from the literature, and thus it can be seen as a generalization that unifies several results in the field.

description: Das Working Paper nimmt den Zusammenhang von Vergleichen und Erzählen aus einer systematischen und historischen Perspektive in den Blick. Es befasst sich zum einen mit der Frage, wie und vor dem Hintergrund welcher theoretischer Annahmen Konvergenzen, Verflechtungen und Wechselbeziehungen zwischen Vergleichspraktiken und Erzählformen postuliert werden können. Beide Praktiken – so die zentrale These – lassen sich als Kulturtechniken begreifen, die zur Formierung übergreifender Netzwerke in Beziehung gesetzt werden können, welche nicht allein durch sprachoder bildgebundene Repräsentationsprozesse gekennzeichnet sind, sondern diese in umfassendere Dynamiken zeichenhafter Darstellungsformen, sozialer Akteure und materieller Artefakte einbinden. Die systematische Perspektive schließt auch die Frage nach der Verknüpfung von Kulturtechnikforschung und Praxistheorie mit ein. Zum anderen skizziert das Papier vier exemplarische historische Konstellationen, die die moderne Wissenschaftsgeschichte, die europäische Weltreiseliteratur, Vergleiche in Bild-Text-Objekt-Hybriden sowie kuratorische Praktiken in Ausstellungen betreffen, in denen Vergleichs- und Erzählpraktiken je spezifische Wechselwirkungen eingehen und in komplexe Operationsketten mit unterschiedlichen Akteuren eingebunden sind.
description: The working paper focuses on the connection between practices of comparing and narrating from a systematic and historical perspective. On the one hand, it tackles the question of how, and against which backdrop of theoretical assumptions, we can postulate convergences, entanglements, and interrelations between practices of comparing and narrating. The main hypothesis is that both practices can be understood as cultural techniques. They form extensive relational networks, which are not only characterized by language and image related representational processes, but first and foremost by complex dynamics linking symbolic representation, social actors, and material artefacts. The systematic perspective also comprises the question of how the approaches of cultural techniques analysis and practice theory can be related to each other. On the other hand, both the interrelation between practices of comparing and narrating as well as the complex operational chains will be outlined on the basis of four historical case studies. Those studies involve subjects such as modern history of science, European travel literature, comparisons in image-text-object hybrids as well as curatorial practices in exhibitions.

Iterative methods for the delay Lyapunov equation with T-Sylvester preconditioning

Publisher: name: arXiv
Year: 2015
Subjects: subject: Numerical Analysis (math.NA)

description: The delay Lyapunov equation is an important matrix boundary-value problem which arises as an analogue of the Lyapunov equation in the study of time-delay systems $\dot{x}(t) = A_0x(t)+A_1x(t-τ)+B_0u(t)$. We propose a new algorithm for the solution of the delay Lyapunov equation. Our method is based on the fact that the delay Lyapunov equation can be expressed as a linear system of equations, whose unknown is the value $U(τ/2)\in\mathbb{R}^{n\times n}$, i.e., the delay Lyapunov matrix at time $τ/2$. This linear matrix equation with $n^2$ unknowns is solved by adapting a preconditioned iterative method such as GMRES. The action of the $n^2\times n^2$ matrix associated to this linear system can be computed by solving a coupled matrix initial-value problem. A preconditioner for the iterative method is proposed based on solving a T-Sylvester equation $MX+X^TN=C$, for which there are methods available in the literature. We prove that the preconditioner is effective under certain assumptions. The efficiency of the approach is illustrated by applying it to a time-delay system stemmingfrom the discretization of a partial differential equation with delay. Approximate solutions to this problem can be obtained for problems of size up to $n\approx 1000$, i.e., a linear system with $n^2\approx 10^6$ unknowns, a dimension which is outside of the capabilities of the other existing methods for the delay Lyapunov equation.

description: We analyze two large datasets from technological networks with location and social data: user location records from an online location-based social networking service, and anonymized telecommunications data from a European cellphone operator, in order to investigate the differences between individual and group behavior with respect to physical location. We discover agreements between the two datasets: firstly, that individuals are more likely to meet with one friend at a place they have not visited before, but tend to meet at familiar locations when with a larger group. We also find that groups of individuals are more likely to meet at places that their other friends have visited, and that the type of a place strongly affects the propensity for groups to meet there. These differences between group and solo mobility has potential technological applications, for example, in venue recommendation in location-based social networks.

description: Maximally localized Wannier functions are widely used in electronic structure theory for analyses of bonding, electric polarization, orbital magnetization, and for interpolation. The state of the art method for their construction is based on the method of Marzari and Vanderbilt. One of the practical difficulties of this method is guessing functions (initial projections) that approximate the final Wannier functions. Here we present an approach based on optimized projection functions that can construct maximally localized Wannier functions without a guess. We describe and demonstrate this approach on several realistic examples.

description: We prove that the notion of Drinfeld center defines a functor from the category of indecomposable multi-tensor categories with morphisms given by bimodules to that of braided tensor categories with morphisms given by monoidal bimodules. Moreover, we apply some ideas from the physics of topological orders to prove that the center functor restricted to indecomposable multi-fusion categories (with additional conditions on the target category) is fully faithful. As byproducts, we provide new proofs to some important known results in fusion categories. In physics, this fully faithful functor gives the precise mathematical description of the boundary-bulk relation for 2+1D anomaly-free topological orders with gapped boundaries.

description: Galaxy clusters form in dense regions of dark matter halos. These halos presumably grow by accreting smaller halos, which are preferentially accreted along the direction of cosmic filaments. In this scenario, halos are not expected to be spherical. Theoretical studies have shown that the major axis of cluster central galaxies tends to align with the major axis of halos. Likewise, the distribution of red cluster satellites tends to be elongated in the direction of the halo elongation. Several observational studies support the theoretical results, with alignment detected between cluster central and satellite galaxy distributions. Utilising J-PLUS and an associated cluster catalogue currently in development, we intend to further study the link between halos and galaxies. In this poster we present preliminary results using another cluster catalogue for cluster selection.
Supermassive Black Hole Seed Formation at High Redshifts: Long-Term Evolution of the Direct Collapse

description: We use cosmological adaptive mesh refinement (AMR) code Enzo zoom-in simulations to study the long term evolution of the collapsing gas within dark matter (DM) halos at high redshifts. This direct collapse process is a leading candidate for rapid formation of supermassive black hole (SMBH) seeds at high z. To circumvent the Courant condition at small radii, we have used the sink particle method, and focus on the evolution on scales ~0.01-10 pc. The collapse proceeds in two stages, with the secondary runaway happening within the central 10 pc, and with no detected fragmentation. The sink particles form when the collapsing gas requires additional refinement of the grid size at the highest refinement level. Their mass never exceeds ~10^3 Mo, with the sole exception of the central seed which grows dramatically to ~ 2 x 10^6 Mo in ~2 Myr, confirming the feasibility of this path to the SMBH. The time variability of angular momentum axis in the accreted gas results in the formation of two misaligned disks --- a small inner disk, and a more massive, outer disk which is inclined by ~45^o to the inner disk. The self-gravity of these disks is heavily diluted --- both disks lie within the Roche limit of the central seed. While the inner disk is geometrically thin and weakly asymmetric, the outer disk flares due to turbulent motions as a result of the massive inflow along a pair of penetrating filaments. The geometry of inflow via filaments determines the dominant and secondary Fourier modes in this disk --- these modes have a non-self-gravitational origin. We do not confirm that m=1 is a principal mode that drives the inflow in the presence of a central massive object. While the positions of the disks depend on the scale chosen to break the self-similar collapse, the overall configuration appears to be generic, and is expected to form when the central seed becomes sufficiently massive.

Modulus of continuity eigenvalue bounds for homogeneous graphs and convex subgraphs with applications to quantum Hamiltonians

description: We adapt modulus of continuity estimates to the study of spectra of combinatorial graph Laplacians, as well as the Dirichlet spectra of certain weighted Laplacians. The latter case is equivalent to stoquastic Hamiltonians and is of current interest in both condensed matter physics and quantum computing. In particular, we introduce a new technique which bounds the spectral gap of such Laplacians (Hamiltonians) by studying the limiting behavior of the oscillations of their eigenvectors when introduced into the heat equation. Our approach is based on recent advances in the PDE literature, which include a proof of the fundamental gap theorem by Andrews and Clutterbuck.
