description: Distributed complex event processing is a method of tracking, analyzing,
processing and detecting specific events or patterns of events that may occur
in event data streams from various distributed sources. Every node within a
network does in-situ processing from its sources. This way of handling large
sets of data whose sources may be geographically scattered, has a couple of
advantages over centralizing the data into a single node and process them
there. The amount of information is potentially vast and limitations of the
available bandwidth render this approach impractical. Thus, a distributed
approach is implemented for communication efficiency. Additionally, having
a single node do all the processing and synchronizations of the network
creates a Single Point of Failure (SPOF) making the system unreliable when
real-time processing is important.
For these reasons, an architecture of an in situ complex event processing
is developed using the Apache Storm primitives. The architecture detects
patterns of interest on incoming event data streams over a number of nodes
in the network in real-time. The patterns, events and network agents are
specified from a user in a file and the system is designed to support multiple
such queries as well as to adapt to any significant changes in the network.

description: High pressure electrical resistance and x-ray diffraction measurements have been performed on ruthenium-doped Ba(Fe0.9Ru0.1)2As2, up to pressures of 32 GPa and down to temperatures of 10 K, using designer diamond anvils under quasi-hydrostatic conditions. At 3.9 GPa, there is an evidence of pressure-induced superconductivity with Tc onset of 24 K and zero resistance at Tc zero of ~14.5 K. The superconducting transition temperature reaches maximum at ~5.5 GPa and then decreases gradually with increase in pressure before completely disappearing above 11.5 GPa. Upon increasing pressure at 200 K, an isostructural phase transition from a tetragonal (I4/mmm) phase to a collapsed tetragonal phase is observed at 14 GPa and the collapsed phase persists up to at least 30 GPa. The changes in the unit cell dimensions are highly anisotropic across the phase transition and are qualitatively similar to those observed in undoped BaFe2As2 parent.

description: The increased need for fast computational systems that can process large streaming inputs in real-time, combined with the limits in parallelism of the CPU's and the difficulties of FPGA based designs have led the hardware community in the search for alternatives. In this diploma thesis, we present a design that leverages the vast parallel capabilities of current GPU's that contain thousands of cores. We implement on a CUDA-enabled GPU two designs of the Hayashi-Yoshida correlation coefficient estimator algorithm, with and without window, for large inputs and we can yield an impressive fifteen-fold and twenty-fold decrease in overall computing latency respectively, coupled with the ability to handle simultaneously up to 18000 inputs.

Sep.), five larvae on hosts preserved in 80% ethanol.
 Biological notes. Eggs and larvae of Z. albicoxa were exclusively parasitic on juvenile spiders (Fig. 1). They were usually located on the dorso-lateral to lateral face, near the base of the abdomen, as were those of Japanese populations. The cocoon hung from the centre of the irregular three-dimensional web and was sustained by several horizontal frame threads (Fig. 2). Table 1 shows the numbers of the spiders and the parasitoids found in the study area in the rainy and dry season. The spider was more abundant in the dry season. Populations of the parasitoid wasp in both rainy and dry seasons were similar; thus the percentage parasitism in the rainy season was higher than in the dry season. The spiders, as well as the parasitoids at a variety of developmental stages, were recognized in both seasons (note that egg sacs of the spider existed in both seasons although we did not count them). The fact that eggs of the parasitoid wasp existed indicates that adult wasps are actively ovipositing regardless of season.
 Distribution. Japan, Russian Far East, Sakhalin, Kuril Islands, China, India, Europe, Indonesia (new record).

description: Στα πλαίσια της συγκεκριμένης διπλωματικής εργασίας αναπτύχθηκε μία εφαρμογή για Android πλατφόρμες. Αποτελεί μια εφαρμογή που απευθύνεται σε εργοθεραπευτές και θα χρησιμοποιείται σαν ένα ακόμα εργαλείο για την αντιμετώπιση των μαθησιακών δυσκολιών παιδιών με Διαταραχή Ελλειμματικής Προσοχής και Υπερκινητικότητα (Δ.Ε.Π.Υ.), ηλικίας από 4 έως 7 ετών. Στο πρώτο στάδιο της υλοποίησης  δημιουργήθηκαν τα Personas της εφαρμογής. Με τον όρο Personas αναφερόμαστε σε ένα σύνολο πρότυπων προσωπικοτήτων που πρόκειται να χρησιμοποιήσουν το προϊόν. Έπειτα δημιουργήθηκαν τα Use Cases που περιγράφουν τη συμπεριφορά του συστήματος κάτω από διαφορετικές συνθήκες, δεδομένου ότι ανταποκρίνεται σε κάποιο αίτημα. Ακολούθως δημιουργήθηκαν τα Paper Prototypes σύμφωνα με τους κανόνες ευρεσιτεχνίες ευχρηστίας για το σχεδιασμό διεπαφής χρήστη. Στη συνέχεια με την βοήθεια ειδικών (εργοθεραπευτής, User Interface designer, ηλεκτρονικό μηχανικό) διορθώθηκαν τα πρώτα λάθη της σχεδίασης ακολουθώντας τη μέθοδο επιθεώρησης χρηστικότητας Cognitive Walkthrough. Έπειτα δημιουργήθηκαν διορθωμένα ψηφιακά Paper Prototypes και με βάση αυτά άρχισε το στάδιο υλοποίησης της εφαρμογής.
	Η υλοποίηση ξεκίνησε δημιουργώντας μία βάση δεδομένων που θα αποθηκεύει τα προφίλ των παιδιών και το ιστορικό των παιχνιδιών που έχουν λάβει μέρος. Η βάση δεδομένων σχεδιάστηκε σύμφωνα με τα διαγράμματα Entity-Relation (E-R) schema, UML diagram και Relational schema. Στη συνέχεια υλοποιήσαμε τις δραστηριότητες που περιλαμβάνει η εφαρμογή και οι οποίες είναι ταξινομημένες ανά θεματικές ενότητες. Οι ενότητες αυτές είναι οι εξής: χρώματα, σχήματα, μνήμη, παζλ, αναγνώριση αντικειμένων και προσανατολισμός. Η εφαρμογή αναπτύχθηκε στο περιβάλλον ανάπτυξης παιχνιδιών Unity3D χρησιμοποιώντας την γλώσσα προγραμματισμού C# μια γλώσσα αντικειμενοστραφή προγραμματισμού παρόμοια με την Java. Η διασύνδεση της βάσης δεδομένων με την εφαρμογή εξασφαλίσθηκε χρησιμοποιώντας την γλώσσα προγραμματισμού SQLite. Καθ’ όλη την διάρκεια της υλοποίησης κρατούσαμε ενήμερη την εργοθεραπεύτρια για τα βήματα που ακολουθούσαμε και έχοντας μια άψογη συνεργασία και συζητώντας προτάσεις και βελτιώσεις μαζί της φτάσαμε στην ολοκλήρωση της εφαρμογής. Με την ολοκλήρωση της εφαρμογής, η εφαρμογή δόθηκε στη εργοθεραπεύτρια για να χρησιμοποιηθεί σε παιδιά με Διαταραχή Ελλειμματικής Προσοχής και Υπερκινητικότητα. Τέλος, μετά και την αξιολόγηση της εφαρμογής από το εργοθεραπευτή δημιουργήθηκε μια συνολική εικόνα και γεννήθηκαν οι προβληματισμοί και οι ιδέες για νέες επεκτάσεις και διορθώσεις στο μέλλον.

description: The experiments show that 30 virus-induced or virus-specified proteins were synthesized in Raji cells after superinfection with Epstein-Barr virus (EBV) derived from P3HR1 cells. Using a combination of pulse labelling, application of cycloheximide blocks at different times post-infection, treatment with amino acid analogues and inhibition of DNA synthesis it was shown that three groups of proteins appear in Raji cells after superinfection; the synthesis of the proteins in any one group appears to be coordinately regulated. Amongst the six virus-induced proteins which were synthesized immediately after release from an early cycloheximide block one would expect to find those proteins essential for the transition from EBNA to EA synthesis. Using human sera with differing specificities for the various antigen groups 11 proteins were identified as being specifically precipitated by sera having high titres against the EBV-induced early antigen complex.

description: When a generic quantum system is prepared in a simple initial condition, it typically equilibrates toward a state that can be described by a thermal ensemble. A known exception are localized systems which are non-ergodic and do not thermalize, however local observables are still believed to become stationary. Here we demonstrate that this general picture is incomplete by constructing product states which feature periodic high-fidelity revivals of the full wavefunction and local observables that oscillate indefinitely. The system neither equilibrates nor thermalizes. This is analogous to the phenomenon of weak ergodicity breaking due to many-body scars and challenges aspects of the current MBL phenomenology, such as the logarithmic growth of the entanglement entropy. To support our claim, we combine analytic arguments with large-scale tensor network numerics for the disordered Heisenberg chain. Our results hold for arbitrarily long times in chains of 160 sites up to machine precision.

We have studied the neutron and gamma-ray induced nucleation events in a SDD with the active liquid R-12 (CCl2F2, b.p. -29.8oC) using a condenser microphone sensor. A comparative study in the low frequency region (~ 0-10kHz) for the neutron and gamma-ray induced nucleation is presented here. From the analysis of the waveforms we observe a significant difference between the neutron and gamma-ray induced acoustic events.

description: Regularization is one of the most fundamental topics in optimization, statistics and machine learning. To get sparsity in estimating a parameter $u\in\mathbb{R}^d$, an $\ell_q$ penalty term, $\Vert u\Vert_q$, is usually added to the objective function. What is the probabilistic distribution corresponding to such $\ell_q$ penalty? What is the correct stochastic process corresponding to $\Vert u\Vert_q$ when we model functions $u\in L^q$? This is important for statistically modeling large dimensional objects, e.g. images, with penalty to preserve certainty properties, e.g. edges in the image. In this work, we generalize the $q$-exponential distribution (with density proportional to) $\exp{(- \frac{1}{2}|u|^q)}$ to a stochastic process named $Q$-exponential (Q-EP) process that corresponds to the $L_q$ regularization of functions. The key step is to specify consistent multivariate $q$-exponential distributions by choosing from a large family of elliptic contour distributions. The work is closely related to Besov process which is usually defined by the expanded series. Q-EP can be regarded as a definition of Besov process with explicit probabilistic formulation and direct control on the correlation length. From the Bayesian perspective, Q-EP provides a flexible prior on functions with sharper penalty ($q<2$) than the commonly used Gaussian process (GP). We compare GP, Besov and Q-EP in modeling functional data, reconstructing images, and solving inverse problems and demonstrate the advantage of our proposed methodology.

description: In genetical genomics studies, it is important to jointly analyze gene expression data and genetic variants in exploring their associations with complex traits, where the dimensionality of gene expressions and genetic variants can both be much larger than the sample size. Motivated by such modern applications, we consider the problem of variable selection and estimation in high-dimensional sparse instrumental variables models. To overcome the difficulty of high dimensionality and unknown optimal instruments, we propose a two-stage regularization framework for identifying and estimating important covariate effects while selecting and estimating optimal instruments. The methodology extends the classical two-stage least squares estimator to high dimensions by exploiting sparsity using sparsity-inducing penalty functions in both stages. The resulting procedure is efficiently implemented by coordinate descent optimization. For the representative $L_1$ regularization and a class of concave regularization methods, we establish estimation, prediction, and model selection properties of the two-stage regularized estimators in the high-dimensional setting where the dimensionality of covariates and instruments are both allowed to grow exponentially with the sample size. The practical performance of the proposed method is evaluated by simulation studies and its usefulness is illustrated by an analysis of mouse obesity data. Supplementary materials for this article are available online.

description: This thesis presents evidence on the relationship between the people’s perception of the quality of their country’s formal institutions and their likelihood to express higher levels of social trust. I use regression analysis in a quasi-experimental framework in order to measure the differential effect of a variation in institutional quality on the evolution of social trust among individuals who possess different characteristics, which make them more or less likely to perceive and appreciate that variation. I use World Values Survey and the European Values Survey cross-sectional survey data that covers the period 1993 through 2012 in six waves. The variation used is the creation and subsequent success of a powerful anticorruption agency in Romania that has been tasked with the prosecution of high-profile individuals in corruption-related offenses since 2006. I find that the institutional variation has a stronger effect upon the evolution of generalized social trust among urban respondents in the post-treatment period, but not among frequent newsreaders and those who report a greater level of interest in politics. I also find that the treatment has a positive differential effect on the level of institutional trust reported by frequent newsreader and people who are interested in politics, but not urban respondents. However, given the quasi-experimental nature of the research design and the limitations of the two datasets used in this thesis, causal identification is difficult and the empirical results should therefore be interpreted with caution.

description: Background: Directional, deep-brain stimulation may prove beneficial for targets (1) thinner along the lead trajectory, and (2) whose borders are not easily visible by neuroimaging. When targeting the ventral intermediate (VIM) nucleus of the thalamus for essential tremor, even baseline ataxia may be exacerbated by medial spread of current and antidromic stimulation of vestibular-cerebellar-thalamic afferents. Case Report: The present patient with essential tremor developed refractory head tremor leading to implantation of bilateral St. Jude/Abbott segmented leads into the VIM to afford additional programming options. Discussion: Video evidence showed that directional stimulation did not exacerbate ataxia beyond baseline, whereas nondirectional stimulation exacerbated ataxia consistently. We discuss how this programming advantage may help address a common complication from DBS implantation for essential tremor patients.

description: We present a detailed structural and morphological study of a large sample of spectroscopically-confirmed galaxies at z >= 6, using deep HST near-IR broad-band images and Subaru optical narrow-band images. The galaxy sample consists of 51 Lyman-alpha emitters (LAEs) at z ~ 5.7, 6.5, and 7.0, and 16 Lyman-break galaxies (LBGs) at 5.9 < z < 6.5. These galaxies exhibit a wide range of rest-frame UV continuum morphology in the HST images, from compact features to multiple component systems. The fraction of merging/interacting galaxies reaches 40% ~ 50% at the brightest end of M_1500 <= -20.5 mag. The intrinsic half-light radii r_{hl,in}, after correction for PSF broadening, are roughly between r_{hl,in} ~ 0.05" (0.3 kpc) and 0.3" (1.7 kpc) at M_1500 <= -19.5 mag. The median r_{hl,in} value is 0.16" (~0.9 kpc). This is consistent with the sizes of bright LAEs and LBGs at z >= 6 in previous studies. In addition, more luminous galaxies tend to have larger sizes, exhibiting a weak size-luminosity relation r_{hl,in} \propto L^{0.14} at M_1500 <= -19.5 mag. The slope of 0.14 is significantly flatter than those in fainter LBG samples. We discuss the morphology of z >= 6 galaxies with nonparametric methods, including the CAS system and the Gini and M_20 parameters, and demonstrate their validity through simulations. We search for extended Lyman-alpha emission halos around LAEs at z ~ 5.7 and 6.5, by stacking a number of narrow-band images. We do not find evidence of extended halos predicted by cosmological simulations. Such Lyman-alpha halos, if they exist, could be weaker than predicted. Finally, we investigate any positional misalignment between UV continuum and Lyman-alpha emission in LAEs. While the two positions are generally consistent, several merging galaxies show significant positional differences. This is likely caused by a disturbed ISM distribution due to merging activity.

Chorea

description: Clinical Vignette: A 73-year-old female with essential tremor (ET) underwent bilateral thalamic ventralis intermedius (Vim) deep brain stimulation (DBS) surgery. The leads provided tremor benefit, but the location was suboptimal and contributed to stimulation-induced hemichorea. Clinical Dilemma: Can patients with ET derive benefit when stimulating outside the Vim? What do we know about stimulation-induced hemichorea in the setting of ET? Clinical Solution: Lead localization combined with advanced programming strategies can be employed to troubleshoot DBS in settings when benefits are observed along with adverse effects. Gap in Knowledge: Sparse information exists about DBS when applied to neuroanatomic regions outside the Vim for the management of ET. Subthalamic nucleus DBS-induced chorea has been reported in multiple movement disorders, but not in ET.

description: Multi-robot motion planning (MRMP) is the problem of finding collision-free paths for a set of robots in a continuous state space. The difficulty of MRMP increases with the number of robots and is exacerbated in environments with narrow passages that robots must pass through, like warehouse aisles where coordination between robots is required. In single-robot settings, topology-guided motion planning methods have shown improved performance in these constricted environments. In this work, we extend an existing topology-guided single-robot motion planning method to the multi-robot domain to leverage the improved efficiency provided by topological guidance. We demonstrate our method's ability to efficiently plan paths in complex environments with many narrow passages, scaling to robot teams of size up to 25 times larger than existing methods in this class of problems. By leveraging knowledge of the topology of the environment, we also find higher-quality solutions than other methods.

description: We report on observation of pronounced terahertz radiation-induced magnetoresistivity oscillations in AlGaAs/GaAs two-dimensional electron systems, the terahertz analog of the microwave induced resistivity oscillations (MIRO). Applying high-power radiation of a pulsed molecular laser we demonstrate that MIRO, so far observed at low power only, are not destroyed even at very high intensities. Experiments with radiation intensity ranging over five orders of magnitude from 0.1 to 10(4)W/cm(2) reveal high-power saturation of the MIRO amplitude, which is well described by an empirical fit function I/(1 + I/I-s)(beta) with beta similar to 1. The saturation intensity Is is of the order of tens of watts per square centimeter and increases by a factor of 6 by increasing the radiation frequency from 0.6 to 1.1 THz. The results are discussed in terms of microscopic mechanisms of MIRO and compared to nonlinear effects observed earlier at significantly lower excitation frequencies.

description: Context: Insurers and health care providers are investing heavily in nonmedical social interventions in an effort to improve health and potentially reduce health care costs. Methods: We performed a systematic review and meta-analysis of all known randomized social experiments in the United States that included health outcomes. We reviewed 5,880 papers, reports, and data sources, ultimately in- cluding 61 publications from 38 randomized social experiments. After synthe- sizing the main findings narratively, we conducted risk of bias analyses, power analyses, and random-effects meta-analyses where possible. Finally, we used multivariate regressions to determine which study characteristics were associ- ated with statistically significant improvements in health outcomes. Findings: The risk of bias was low in 17 studies, moderate in 11, and high in 33. Of the 451 parameter estimates reported, 77% were underpowered to detect health outcomes. Among adequately powered parameters, 49% demonstrated a significant health improvement, 44% had no effect on health, and 7% were associated with significant worsening of health. In meta-analyses, early life and education interventions were associated with a reduction in smoking (odds ratio [OR] = 0.92, 95% confidence interval [CI] 0.86-0.99). Income maintenance and health insurance interventions were associated with significant improve- ments in self-rated health (OR = 1.20, 95% CI 1.06-1.36, and OR = 1.38, 95% CI 1.10-1.73, respectively), whereas some welfare-to-work interventions had a negative impact on self-rated health (OR = 0.77, 95% CI 0.66-0.90). Housing and neighborhood trials had no effect on the outcomes included in the meta-analyses. A positive effect of the trial on its primary socioeconomic outcome was associated with higher odds of reporting health improvements. We found evidence of publication bias for studies with null findings. Conclusions: Early life, income, and health insurance interventions have the potential to improve health. However, many of the included studies were underpowered to detect health effects and were at high or moderate risk of bias. Future social policy experiments should be better designed to measure the association between interventions and health outcomes.

description: Clustering is a fundamental problem in many scientific applications. Standard methods such as $k$-means, Gaussian mixture models, and hierarchical clustering, however, are beset by local minima, which are sometimes drastically suboptimal. Recently introduced convex relaxations of $k$-means and hierarchical clustering shrink cluster centroids toward one another and ensure a unique global minimizer. In this work we present two splitting methods for solving the convex clustering problem. The first is an instance of the alternating direction method of multipliers (ADMM); the second is an instance of the alternating minimization algorithm (AMA). In contrast to previously considered algorithms, our ADMM and AMA formulations provide simple and unified frameworks for solving the convex clustering problem under the previously studied norms and open the door to potentially novel norms. We demonstrate the performance of our algorithm on both simulated and real data examples. While the differences between the two algorithms appear to be minor on the surface, complexity analysis and numerical experiments show AMA to be significantly more efficient.

description: We study low-energy scattering of spin-1/2 baryons from the perspective of quantum information science, focusing on the correlation between entanglement minimization and the appearance of accidental symmetries. The baryon transforms as an octet under the SU(3) flavor symmetry and its interactions below the pion threshold are described by contact operators in an effective field theory (EFT) of QCD. Despite there being 64 channels in the 2-to-2 scattering, only six independent operators in the EFT are predicted by SU(3). We show that successive entanglement minimization in SU(3)-symmetric channels are correlated with increasingly large emergent symmetries in the EFT. In particular, we identify scattering channels whose entanglement suppression are indicative of emergent SU(6), SO(8), SU(8), and SU(16) symmetries. We also observe the appearance of non-relativistic conformal invariance in channels with unnaturally large scattering lengths. Improved precision from lattice simulations could help determine the degree of entanglement suppression, and consequently the amount of accidental symmetry, in low-energy QCD.

Y-system for form factors at strong coupling in AdS5 and with multi-operator insertions in AdS3

description: We study form factors in N=4 SYM at strong coupling in general kinematics and with multi-operator insertions by using gauge/string duality and integrability techniques. This generalizes the AdS3 results of Maldacena and Zhiboedov in two non-trivial aspects. The first generalization to AdS5 space was motivated by its potential connection to strong coupling Higgs-to-three-gluons amplitudes in QCD which was observed recently at weak coupling. The second generalization to multi-operator insertions was motivated as a step towards applying on-shell techniques to compute correlation functions at strong coupling. In this picture, each operator is associated to a monodromy condition on the cusp solutions. We construct Y-systems for both cases. The Y-functions are related to the spacetime (cross) ratios. Their WKB approximations based on a rational function P(z) are also studied. We focus on the short operators, while the prescription is hopefully also applicable for more general operators.

description: We investigate the application of nanoscale topgates on exfoliated bilayer graphene to define quantum dot devices. At temperatures below 500 mK the conductance underneath the grounded gates is suppressed, which we attribute to nearest neighbour hopping and strain-induced piezoelectric fields. The gate-layout can thus be used to define resistive regions by tuning into the corresponding temperature range. We use this method to define a quantum dot structure in bilayer graphene showing Coulomb blockade oscillations consistent with the gate layout.
