description: We introduce a new class of spintronics devices in which a spin-valve like effect results from strong spin-orbit coupling in a single ferromagnetic layer rather than from injection and detection of a spin-polarized current by two coupled ferromagnets. The effect is observed in a normal-metal/insulator/ferromagnetic-semiconductor tunneling device. This behavior is caused by the interplay of the anisotropic density of states in (Ga,Mn)As with respect to the magnetization direction, and the two-step magnetization reversal process in this material.

description: By combining single crystal x-ray and neutron diffraction, and the magnetodielectric measurements on single crystal Fe4Nb2O9, we present the magnetic structure and the symmetry-allowed magnetoelectric coupling in Fe4Nb2O9. It undergoes an antiferromagnetic transition at TN=93 K, followed by a displacive transition at TS=70 K. The temperature-dependent dielectric constant of Fe4Nb2O9 is strongly anisotropic with the first anomaly at 93 K due to the exchange striction as a result of the long range spin order, and the second one at 70 K emanating from the structural phase transition primarily driven by the O atomic displacements. Magneticfield induced magnetoelectric coupling was observed in single crystal Fe4Nb2O9 and is compatible with the solved magnetic structure that is characteristic of antiferromagnetically arranged ferromagnetic chains in the honeycomb plane. We propose that such magnetic symmetry should be immune to external magnetic fields to some extent favored by the freedom of rotation of moments in the honeycomb plane, laying out a promising system to control the magnetoelectric properties by magnetic fields.

description: The treatment of hydrocephalus often involves the placement of a shunt catheter into the cerebrospinal ventricular space, though such ventricular catheters often fail by tissue obstruction. While diverse cell types contribute to the obstruction, astrocytes are believed to contribute to late catheter failure that can occur months after shunt insertion. Using in vitro microfluidic cultures of astrocytes, we show that applied fluid shear stress leads to a decrease of cell confluency and the loss of their typical stellate cell morphology. Furthermore, we show that astrocytes exposed to moderate shear stress for an extended period of time are detached more easily upon suddenly imposed high fluid shear stress. In the light of these findings and examining the range of values of wall shear stress in a typical ventricular catheter through computational fluid dynamics (CFD) simulation, we find that the typical geometry of ventricular catheters has low wall shear stress zones that can favour the growth and adhesion of astrocytes, thus promoting obstruction. Using high-precision direct flow visualization and CFD simulations, we discover that the catheter flow can be formulated as a network of Poiseuille flows. Based on this observation, we leverage a Poiseuille network model to optimize ventricular catheter design such that the distribution of wall shear stress is above a critical threshold to minimize astrocyte adhesion and growth. Using this approach, we also suggest a novel design that not only optimizes the wall shear stress distribution but also eliminates a stagnation zone with low wall shear stress, which is common to current ventricular catheters.

description: We study theoretically and experimentally the quantum properties of a type II frequency degenerate optical parametric oscillator below threshold with a quarter-wave plate inserted inside the cavity which induces a linear coupling between the orthogonally polarized signal and idler fields. This original device provides a good insight into general properties of two-mode gaussian states, illustrated in terms of covariance matrix. We report on the experimental generation of two-mode squeezed vacuum on non-orthogonal quadratures depending on the plate angle. After a simple operation, the entanglement is maximized and put into standard form, \textit{i.e.} quantum correlations and anti-correlations on orthogonal quadratures. A half-sum of squeezed variances as low as $0.33 \pm 0.02$, well below the unit limit for inseparability, is obtained and the entanglement measured by the entropy of formation.

description: In the first paper of this series (Paper I) we computed time dependent simulations of multifluid shocks with chemistry and a transverse magnetic field frozen in the ions, using an adaptive moving grid. In this paper, we present new analytical results on steady-state molecular shocks. Relationships between density and pressure in the neutral fluid are derived for the cold magnetic precursor, hot magnetic precursor, adiabatic shock front, and the following cooling layer. The compression ratio and temperature behind a fully dissociative adiabatic shock is also derived. To prove that these results may even hold for intermediate ages, we design a test to locally characterise the validity of the steady state equations in a time-dependent shock simulation. Applying this tool to the results of Paper I, we show that most of these shocks (all the stable ones) are indeed in a quasi-steady state at all times, i.e. : a given snapshot is composed of one or more truncated steady shock. Finally, we use this property to produce a construction method of any intermediate time of low velocity shocks (u < 20 km/s) with only a steady-state code. In particular, this method allows one to predict the occurrence of steady CJ-type shocks more accurately than previously proposed criteria.

description: We carry out a theoretical investigation of overpressurized superfluid phases of He-4 by means of quantum Monte Carlo (QMC) simulations. As a function of density, we study structural and superfluid properties, and estimate the energy of the roton excitation by inverting imaginary-time density correlation functions computed by QMC, using Maximum Entropy. We estimate the pressure at which the roton energy vanishes to be about 100 bars, which we identify with the spinodal density, i.e., the upper limit for the existence of a metastable superfluid phase.

description: In Probabilistic Logic Programming (PLP) the most commonly studied inference task is to compute the marginal probability of a query given a program. In this paper, we consider two other important tasks in the PLP setting: the Maximum-A-Posteriori (MAP) inference task, which determines the most likely values for a subset of the random variables given evidence on other variables, and the Most Probable Explanation (MPE) task, the instance of MAP where the query variables are the complement of the evidence variables. We present a novel algorithm, included in the PITA reasoner, which tackles these tasks by representing each problem as a Binary Decision Diagram and applying a dynamic programming procedure on it. We compare our algorithm with the version of ProbLog that admits annotated disjunctions and can perform MAP and MPE inference. Experiments on several synthetic datasets show that PITA outperforms ProbLog in many cases.

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The code IAC-star is presented. It generates synthetic HR and color-magnitude diagrams (CMDs) and is mainly aimed to star formation history studies in nearby galaxies. Composite stellar populations are calculated on a star by star basis, by computing the luminosity, effective temperature and gravity of each star by direct bi-logarithmic interpolation in the metallicity and age grid of a library of stellar evolution tracks. Visual (broad band and HST) and infrared magnitudes are also provided for each star after applying bolometric corrections. The Padua (Bertelli et al. 1994, Girardi et al. 2000) and Teramo (Pietrinferni et al. 2004) stellar evolution libraries and various bolometric corrections libraries are used in the current version. A variety of star formation rate functions, initial mass functions and chemical enrichment laws are allowed and binary stars can be computed. Although the main motivation of the code is the computation of synthetic CMDs, it also provides integrated masses, luminosities and magnitudes as well as surface brightness fluctuation luminosities and magnitudes for the total synthetic stellar population, and therefore it can also be used for population synthesis research. The code is offered for free use and can be executed at the site {\tt http://iac-star.iac.es}, with the only requirement of referencing this paper and crediting as indicated in the site.

Transmit beamforming for frequency-selective channels with suboptimum equalization
Creators: name: Liang, Yang Wen
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis, we propose beamforming schemes for frequency-selective channels with decision-feedback equalization (DFE) or linear equalization (LE) at the receiver and with, respectively, perfect and quantized channel state information (CSI) at the transmitter. For beamforming with perfect CSI and infinite impulse response (IIR) beamforming filters (BFFs) we derive a closed-form expression for the optimum BFFs. We also provide two efficient numerical methods for recursive calculation of the optimum finite impulse response (FIR) BFFs with perfect CSI. For beamforming with quantized CSI and finite-rate feedback channel, we propose a global vector quantization (GVQ) algorithm for codebook design. This algorithm is deterministic and independent of initial conditions and does not impose any constraints on the number of transmit and receive antennas, the antenna correlation, or the fading statistics. Our simulation results for typical GSM¹ [1] and EDGE² [2, 3, 4] channels show that in general short FIR BFFs are sufficient to closely approach the performance of IIR BFFs even in severely frequency-selective channels. Furthermore, finite-rate feedback beamforming with only a few feedback bits achieves significant performance gains over single-antenna transmission, transmit antenna selection, and optimized delay diversity [5] in frequency-selective fading.

description: We consider cosmological models where dark energy is described by a dynamical field equipped with the Chameleon screening mechanism, which serves to hide its effects in local dense regions and to conform to Solar System observations. In these models, there is no universal gravitational coupling and here we study the effective couplings that determine the force between massive objects, $G_N$, and the propagation of gravitational waves, $G_{gw}$. In particular, we revisit the Chameleon screening mechanism without neglecting the time dependence of the galactic environment where local regions are embedded in, and analyze the induced time evolution on $G_N$ and $G_{gw}$, which can be tested with Lunar Laser Ranging and direct gravitational waves observations. We explicitly show how and why these two couplings generically differ. We also find that due to the particular way the Chameleon screening mechanism works, their time evolutions are highly suppressed in the weak-field non-relativistic approximation.

Dennoch, wie genau die Eigenschaften einzelner Neuronen und die Wechselwirkungen mit verbundenen Zellen unterschiedliche Verhaltensweisen hervorrufen, wie zum Beispiel die Fortbewegung, ist noch nicht bekannt. Aufgrund der hohen Nummer an noch nicht bekannten Parametern des Nervensystems, können verschiedene Hypothesen, über die notwendigen Bedingungen für das Einleiten von Verhalten, aufgestellt werden. In dieser Arbeit stellen wir ein neues, biologisch grundiertes, Modell eines neuronalen Netzwerkes vor, verantwortlich für die Generierung koordinierter Muskelaktivität, die dazu führt, dass sich der Wurm vorwärts bewegt. Das Modell umfasst, neben den Muskeln, einen Teil des Nervensystems des Wurms, welcher bekannt dafür ist für das Indizieren der Fortbewegung verantwortlich zu sein. Neuronen und Muskeln sind als Single-Compartment Zellen modelliert. Ihr Membranpotential wir mithilfe eines Hodgkin-Huxley Modell berechnet, welches beschreibt, wie sich das Membranpotential ändert, wenn sich Ionen durch die Membran hindurch bewegen. Wir implementieren unser neues Modell innerhalb der OpenWorm Plattform, um das Nervensystem und den Körper des Wurms zu Simulieren und zeigen, dass unser Modell in der Lage ist Vorwärtsbewegung einzuleiten. Um Wissenschafter zu Helfen ihre eigenen in silico Experimente mit OpenWorm zu definieren, erstellen wir ein Docker image welches eine Toolchain von OpenWorm Programmen und Skripten beinhaltet. Die generierten Daten über das Verhalten eines simulierten Wurms können mit Daten echter Würmer verglichen werden, um die Ergebnisse der Experimente zu Validieren.

description: An analysis of the X-ray variability of the low luminosity Seyfert nucleus NGC 4395, based on a long XMM-Newton observation, is presented. The power spectrum shows a clear break from a flat spectrum (alpha ~ 1) to a steeper spectrum (alpha ~ 2) at a frequency f_br = 0.5 - 3.0 * 10^-3 Hz, comparable to the highest characteristic frequency found previously in a Seyfert galaxy. This extends the measured M_BH-f_br values to lower M_BH than previous studies of Seyfert galaxies, and is consistent with an inverse scaling of variability frequency with black hole mass. The variations observed are among the most violent seen in an AGN to date, with the fractional rms amplitude (F_var) exceeding 100 per cent in the softest band. The amplitude of the variations seems intrinsically higher in NGC 4395 than most other Seyferts, even after accounting for the differences in characteristic frequencies. The origin of this difference is not clear, but it is unlikely to be a high accretion rate (L/L_Edd < 20 per cent for NGC 4395). The variations clearly follow the linear rms-flux relation, further supporting the idea that this is a ubiquitous characteristics of accreting black holes. The variations are highly coherent between different energy bands with any frequency-dependent time delay limited to <1 per cent.

Pittel, Phys. Rev. Lett. 86, 4791, 2001.), using an exactly solvable model with a repulsive pairing interaction between bosons it has been shown that the ground state is described almost completely in terms of S and D bosons. In the present paper we study the excited states obtained within this exactly solvable hamiltonian and show that in order to obtain a rotational spectra all the other degrees of freedom are needed.

Searches for narrow baryonic states in the decay channels K^0_s p, K^+ p, Xi^- pi^{+-}, anti-XI^+ pi^{+-} and D^{*+-}p^{-+} are reported. The results support the existence of a narrow resonance decaying into K^0_s p and K^0_s anti-p, consistent with the Theta(1530) state. No signals are seen in the K^+ p, Xi^- pi^{+-}, anti-Xi^+ pi^{+-} and D^{*+-}p{-+} channels.

description: There is a growing recognition that artists use valuable ways to understand and work with cognitive and perceptual mechanisms to convey desired experiences and narrative in their created artworks (DiPaola et al., 2010; Zeki, 2001). This paper documents our attempt to computationally model the creative process of a portrait painter, who relies on understanding human traits (i.e., personality and emotions) to inform their art. Our system includes an empathic conversational interaction component to capture the dominant personality category of the user and a generative AI Portraiture system that uses this categorization to create a personalized stylization of the user's portrait. This paper includes the description of our systems and the real-time interaction results obtained during the demonstration session of the NeurIPS 2019 Conference.

description: We study the smectic AC transition in anisotropic and uniaxial disordered environments, e.g., aerogel with an external field. We find very strange behavior of translational correlations: the low-temperature, lower-symmetry Smectic C phase is itless translationally ordered than the it high-temperature, higher-symmetry Smectic A phase, with short-ranged and algebraic translational correlations, respectively. Specifically, the A and C phase belong to the quasi-long-ranged translationally ordered " XY Bragg glass '' and short-ranged translationally ordered " m=1 Bragg glass '' phase, respectively. The AC phase transition itself belongs to a new universality class, whose fixed points and exponents we find in a d=5-epsilon expansion.

description: We proposed that the spectral evolution of transient X-ray binaries (XrB) is due to an interplay between two flows: a standard accretion disk (SAD) in the outer parts and a jet-emitting disk (JED) in the inner parts. We showed in previous papers that the spectral evolution in X-ray and radio during the 2010-2011 outburst of GX339-4 can be recovered. We now investigate the presence of low frequency quasi-periodic oscillations (LFQPOs) during an X-ray outburst, and address the possible correlation between the frequencies of these LFQPOs and the transition radius between the two flows, rJ. We select X-ray and radio data form 3 outbursts of GX339-4. We use the method detailed in paper IV to obtain $r_J(t)$ and $\dot{m}_{in}(t)$ for each outburst to reproduce the correlated evolution of the X-ray spectra and the radio emission for 3 different activity cycles of GX339-4. We also independently search and report the detection of 7 new LFQPOs in addition to the literature. We show that the frequency of Type C QPOs can be linked to the dynamical JED-SAD transition radius rJ, rather than the radius of optically thin-thick transition. The scaling factor q such that $ν_{QPO} \simeq ν_K (r_J) / q$ is $q \simeq 70-140$, consistent during the 4 cycles and similar to previous studies. The JED-SAD hybrid disk configuration not only provides a successful paradigm allowing us to describe XrB cycles, but also matches the QPO frequencies evolution. QPOs provide an indirect way to probe the JED-SAD transition radius, where an undetermined process produces secular variability. The demonstrated relation between the transition radius links Type C QPOs to the transition between the two flows, tying it to the inner magnetized structure of the jets. This direct connection between the jets' structure and the process responsible for Type C QPOs could naturally explain their puzzling multi-wavelength behavior.

Furthermore, self-energies for both 2D as well as 3D cases are derived. Our general formulas can be employed to obtain Madelung constants for periodic structures.

The diagnostic consists of an optical streak camera coupled to a spectrometer to provide temporally and spectrally-resolved records of visible emission from dynamically-compressed materials. Fiber optic coupling to the sample enables a small diagnostic footprint on the target face and flexibility of operation on multiple launch systems without the need for open optics. We present the details of calibration (time, wavelength and spectral radiance) for absolute temperature determination and present benchmark measurements of system performance.

description: We have studied the influence of a square array of pinning centers on the dynamics of vortex avalanches in Pb thin films by means of ac- and dc- magnetization measurements. Close to the superconducting transition Tc the commensurability between the vortex lattice and the pinning array leads to the well known local increments of the critical current. As temperature T decreases, matching features progressively fade out and eventually disappear. Further down in temperature vortex avalanches develop and dominate the magnetic response. These avalanches manifest themselves as jumps in the dc-magnetization and produce a lower ac-shielding giving rise to a paramagnetic reentrance in the ac-screening x'(T). Within the flux jump regime two subregimes can be identified. Close to the boundary where vortex avalanches develope, the field separation between consecutive jumps follow the periodicity of the pinning array and a field and temperature dependent screening is observed. In this regime, the response also depends on frequency f in agreement with theoretical models for magnetothermal instabilities. At low enough temperatures and fields, the screening saturates to a constant value independent of T, H, and f, where jumps are randomly distributed. We have also found that vortex instabilities occupy a larger portion of the H-T diagram in patterned samples than in films without nanoengineered pinning sites. Finally, we discuss the possible origin of the vortex avalanches and compare our results with previous experimental and theoretical studies.

description: The Koopman operator provides a powerful framework for data-driven analysis of dynamical systems. In the last few years, a wealth of numerical methods providing finite-dimensional approximations of the operator have been proposed (e.g. extended dynamic mode decomposition (EDMD) and its variants). While convergence results for EDMD require an infinite number of dictionary elements, recent studies have shown that only few dictionary elements can yield an efficient approximation of the Koopman operator, provided that they are well-chosen through a proper training process. However, this training process typically relies on nonlinear optimization techniques. In this paper, we propose two novel methods based on a reservoir computer to train the dictionary. These methods rely solely on linear convex optimization. We illustrate the efficiency of the method with several numerical examples in the context of data reconstruction, prediction, and computation of the Koopman operator spectrum. These results pave the way to the use of the reservoir computer in the Koopman operator framework.

description: Several studies have analysed the effects of European environmental policies on water quality, but no detailed retrospective analysis of the impacts of the Common Agricultural Policy (CAP) reforms on observed water quality parameters has been carried out. This study evaluates the impact of the CAP and other drivers on the concentrations of nitrates and suspended solids in the Guadalquivir River Basin (southern Spain) over the 1999-2009 period. The most important drivers that are degrading both water quality indicators are exports from upland areas and agricultural intensification. Water quality conditions have improved in regions where there has been abandonment and/or deintensification. The decoupling process has reduced the concentration of nitrates and suspended solids in a number of subbasins. Although agricultural production and water efficiency in the basin have improved, high erosion rates have not yet been addressed.

description: I illustrate the role of infrared renormalons in computing inclusive B-decay spectra. I explain the relation between the leading ambiguity in the definition of Sudakov form factor \sim \exp(NΛ/M) and that of the pole mass, and show how these ambiguities cancel out between the perturbative and non-perturbative components of the b-quark distribution in the meson.

description: Compared to the parental species, interspecific hybrids often show, intermediate phenotypes which can affect their fitness directly and/or their attractiveness to potential mates. Lissotriton montandoni and Lissotriton vulgaris hybridize across their parapatric range along the Carpathian mountains. Hybrids are rare in natural hybrid zones, which may be related to strong assortative mating in parental species. In the present study, we investigated morphological male species-specific traits and their differentiation between both parental species and first generation of interspecific hybrids (F1), considering morphological variation between two L. vulgaris subspecies co-occurring with L. montandoni in nature: L. v. vulgaris and L. v. ampelensis. Male morphology of each group was assessed and compared based on species-specific and sexual secondary traits, selected based on the literature review. We confirmed that F1 hybrids of L. v. vulgaris and L. montandoni have an intermediate morphology between parental species. However, when morphological traits were compared with the level of genetic admixture of individuals in natural hybrid zones, we discovered that even early generations hybrids (i.e. F1 and/or F2 generation) can be similar to the parental species (especially L. v. ampelensis). As even early generations hybrids can be morphologically undistinguishable from L. v. ampelensis, sexual attractiveness of hybrids may be potentially less affected in direction of L. v. ampelensis backcrossing. Summarizing, morphology, especially morphology of male secondary sexual traits is not a reliable tool for the estimation of genetic admixture of an individual in natural populations within the hybrid zone.

description: As more and more Things join the Internet, the interoperability of Things becomes a major concern. Several challenges arise when Things should be able to interoperate with other software components. Since Things enable an enormous area of application, they are highly heterogeneous actors. Things are designed to fit the application context and as a result the data that Things offer varies greatly. Additionally, Things use diverse technologies since their requirements diverge. Software systems that utilise the IoT will have to integrate cloud services, network functions and Things. Such IoT cloud systems will be major enablers of IoT applications. But in order for an IoT cloud system to function, the components of the system have to interoperate with each other. However, the Thing diversity presents a challenge when the interoperability of IoT cloud systems is pursued. Appropriate interoperability solutions are needed to manage the technology and data diversity, such that Things can interoperate with IoT cloud systems. Nevertheless, the technology and data diversity itself is not the only interoperability challenge that needs to be resolved. Things are often mobile and depend strongly on their context and environment. As Things move through the world or change contexts, they will have to dynamically enter and leave IoT cloud systems. It is therefore not sufficient to manage the interoperability problems with static means. Interoperability solutions need to be provided on-demand. Detecting interoperability problems and finding appropriate solutions is still an exhaustive and costly task. Same is true for provisioning and deploying such solutions. However, all of those steps are required to provide on-demand interoperability solutions. The aim of this thesis is to reduce the time and effort that is required to perform those tasks. By modeling the interoperability capabilities of Things, network functions and cloud services with interoperability metadata, we endeavour to detect interoperability problems and recommend solutions. Furthermore, we reuse and deploy software components that are deemed capable of solving the problem. Additionally, we discuss and define the property of on-demand interoperability and several factors that are key to providing on-demand interoperability. We introduce Interoperability DevOps as the main stakeholders of our framework, since complex interoperability problems must be resolved with human intelligence. A proof-of-concept prototype that implements the framework was built during this thesis. The prototype was then used to evaluate the appropriateness of the framework.

description: We analyze the impact of the forthcoming CP-violating observables in the $B_s\to K^+ K^-$ system, combined with the precise measurement of $\sin2β$ , in the extraction of the CKM matrix. Computing the penguin parameters $(r, θ)$ within QCD factorization yields a precise determination of $(\barρ, \barη)$, reflected by a weak dependence on $θ$, which is shown to be a second order effect. Using the SU(3)-flavour symmetry argument and the current $B$-factories data provided by the $B_d \to π^+ π^-$ modes, we complement the $B_s \to K^+ K^-$ CP-violating observables in a variety of ways, in particular we find that $S_{KK}>0$. Finally, we investigate systematically the SU(3)-symmetry breaking factor within QCD factorization.

description: Bienen sind ein wichtiger Bestandteil von Wirtschaft und Umwelt. In den letzten Jahren wurden Bienenstöcke durch Parasiten und anderen Umweltfaktoren bedroht. Aus diesem Grund steigt das Interesse Bienenstöcke automatisch zu überwachen. Mit Hilfe von Videodaten kann so eine Überwachung durchgeführt werden. Diese Arbeit stellt eine Lösung vor, um alle Bienen am Eingang des Stocks gleichzeitig zu tracken und zu zählen, während sie durch eine künstliche Eingangsstruktur gehen. Unter der Verwendung der HSV- und HSL-Farbmodelle kann mit Hilfe von Mathematischer Morphologie eine genaue binäre Segmentierung erreicht werden. Durch Anwendung des K-Means Algorithmus können Cluster von Bienen getrennt werden und das Problem auf Tracking einzelner Bienen vereinfacht werden. Als Ergebnis der Zählung wird eine Fehlerrate von 6.86% auf Extremdaten mit einer Bildrate von rund 67 Bildern pro Sekunde auf einem Desktop-PC erreicht. Vier Datensätze, die mit drei verschiedenen Kameramodellen aufgenommen wurden, werden evaluiert. Ein Langzeittest, welcher Aufnahmen über einen Zeitraum von einer Woche (insgesamt 73 Stunden Videodaten) durchläuft, demonstriert die praktische Anwendbarkeit der Methode.
description: Honey bees are an important part of the environment and economy. Recently bees are threatened by parasites and other environmental factors. This raises the need to automatically monitor bee hives. With the use of video data such a monitoring can be performed. This thesis presents a way to use computer vision to automatically monitor a bee hive. The presented technique is able to simultaneously track and count bees at the hive entrance while they are walking through an artificial entrance structure. By using HSV and HSL color models together with mathematical morphology an accurate binary segmentation can be achieved. With the help of the k-means algorithm bee clusters can be resolved and broken down to single bee tracking. This allows to get counting results with less than 6.86% average error rate on extreme data while running at a framerate of around 67 frames per second on a desktop PC. Four datasets which where recorded with three different camera models have been evaluated. A long-time test which evaluates the algorithm with recordings of a whole week (73 hours in total) demonstrates the practical applicability of the presented method.
