description: Interfaces for creating visualizations typically embrace one of several common forms. Textual specification enables fine-grained control, shelf building facilitates rapid exploration, while chart choosing promotes immediacy and simplicity. Ideally these approaches could be unified to integrate the user- and usage-dependent benefits found in each modality, yet these forms remain distinct. We propose parameterized declarative templates, a simple abstraction mechanism over JSON-based visualization grammars, as a foundation for multimodal visualization editors. We demonstrate how templates can facilitate organization and reuse by factoring the more than 160 charts that constitute Vega-Lite's example gallery into approximately 40 templates. We exemplify the pliability of abstracting over charting grammars by implementing -- as a template -- the functionality of the shelf builder Polestar (a simulacra of Tableau) and a set of templates that emulate the Google Sheets chart chooser. We show how templates support multimodal visualization editing by implementing a prototype and evaluating it through an approachability study.

This research focused on analyzing rainfall events over the western side of the island of Puerto Rico. We hypothesized that rainfall location over the western side of the small Caribbean island is mainly influenced by the confluence of sea breeze and predominant winds, interacting across complex terrain. An in-depth analysis of the science behind these events on the island has not previously been done, which is why this study is important. To analyze these events a variety of data was used; these included satellite reanalyses, radar images, radiosonde soundings, model simulations, and in-situ data. To better understand the winds on this island we conducted a climatological analysis. The results showed that easterly winds are the most predominant, along with some northeasterly and southeasterly winds. In addition, a histogram showed that these winds are seasonal and that easterly and southeasterly winds are more common during the summer, while northeasterly winds are more common during winter and spring. Our results determined that rainfall accumulation and intensity on the western side of the island is mainly due to the predominant wind direction and the location of the resulting sea breeze influencing that event. Rainfall accumulation and location on the western side of the island is due to a combination of the predominant wind direction, the location of the resulting sea breeze, and the influence of terrain on inflow parcel patterns.

description: Tellurite glasses, which contain Tellurium dioxide as the main component, have some remarkable optical properties which are well recognised and exploited in the bulk optics and fibre fields. They include a high acousto-optic figure of merit, wide mid infrared transparency, the highest optical nonlinearity amongst oxides, and excellent rare earth hosting, etc. Despite these attractive properties, until now, no one has succeeded in fabricating low loss planar waveguides in these materials. This work develops high quality optical planar waveguides in Tellurium dioxide for the first time. The project investigates the materials science for optical Tellurium dioxide films and discovers an appropriate waveguide fabrication method. The thin films have been fabricated by reactive radio frequency magnetron sputtering using a Tellurium target in an oxygen and argon atmosphere. Propagation losses at 1550nm in the planar films are 0.1dB/cm or lower in stoichiometric composition. The properties of films have been also found to be stable with thermal annealing up to 300 degree Celsius. Plasma etching of tellurite glasses has been systematically studied. High quality etching of Tellurium dioxide and chalcogenide glass films has been demonstrated with a Methane/Hydrogen/Argon gas mixture. As a result, a fabrication recipe which produces low loss (0.1dB/cm) planar waveguides has been discovered. The nonlinear coefficient of the sputtered TeO2 has been characterised by self-phase modulation (SPM) experiments and the second order nonlinear coefficient has been measured to be around 25 times that of silica. Significant signal conversion, -4dB, has achieved with large bandwidth of 30nm in the four-wave mixing (FWM) experiment pumped at 1550nm in a slightly normal dispersion waveguide. Erbium doped Tellurium oxide thin films have also been fabricated by co-sputtering of Erbium and Tellurium targets into an Oxygen and Argon atmosphere. The obtained films have been found to have good properties for Erbium doped waveguide amplifiers. The Erbium concentration can be controlled within the range of interest with Erbium/Tellurium ratios ranging from 0.1% to 3% or more. The 1.5 micrometre photoluminescence properties of the films are excellent with effective bandwidth of more that 60nm and intrinsic lifetime of order of 3ms. Despite the fact that there was OH contamination in the films, single mode Erbium doped waveguide amplifiers with high internal gain have been successfully obtained. The 1480nm pumped amplifier achieved internal gain from below 1520nm to beyond 1600nm. The peak gain of 2.8dB/cm and 40nm 3dB gain bandwidth have been accomplished. These results are a major stepping stone towards ""system-on-chip"" optical applications for telecom and mid infrared optics given the multifunctional nature of tellurite materials. -- provided by Candidate.

description: We discuss the equivalence between kinetic wealth-exchange models, in which agents exchange wealth during trades, and mechanical models of particles, exchanging energy during collisions. The universality of the underlying dynamics is shown both through a variational approach based on the minimization of the Boltzmann entropy and a complementary microscopic analysis of the collision dynamics of molecules in a gas. In various relevant cases the equilibrium distribution is the same for all these models, namely a gamma-distribution with suitably defined temperature and number of dimensions. This in turn allows one to quantify the inequalities observed in the wealth distributions and suggests that their origin should be traced back to very general underlying mechanisms: for instance, it follows that the smaller the fraction of the relevant quantity (e.g. wealth or energy) that agents can exchange during an interaction, the closer the corresponding equilibrium distribution is to a fair distribution.

description: Graph dynamical systems (GDSs) can be used to describe a wide range of distributed, nonlinear phenomena. In this paper we characterize cycle equivalence of a class of finite GDSs called sequential dynamical systems SDSs. In general, two finite GDSs are cycle equivalent if their periodic orbits are isomorphic as directed graphs. Sequential dynamical systems may be thought of as generalized cellular automata, and use an update order to construct the dynamical system map. The main result of this paper is a characterization of cycle equivalence in terms of shifts and reflections of the SDS update order. We construct two graphs C(Y) and D(Y) whose components describe update orders that give rise to cycle equivalent SDSs. The number of components in C(Y) and D(Y) is an upper bound for the number of cycle equivalence classes one can obtain, and we enumerate these quantities through a recursion relation for several graph classes. The components of these graphs encode dynamical neutrality, the component sizes represent periodic orbit structural stability, and the number of components can be viewed as a system complexity measure.

description: Since May 2020, several COVID-19 outbreaks have occurred in the German meat industry despite various protective measures, and temperature and ventilation conditions were considered as possible high-risk factors. This cross-sectional study examined meat and poultry plants to examine possible risk factors. Companies completed a self-administered questionnaire on the work environment and protective measures taken to prevent SARS-CoV-2 infection. Multivariable logistic regression analysis adjusted for the possibility to distance at least 1.5 meters, break rules, and employment status was performed to identify risk factors associated with COVID-19 cases. Twenty-two meat and poultry plants with 19,072 employees participated. The prevalence of COVID-19 in the seven plants with more than 10 cases was 12.1% and was highest in the deboning and meat cutting area with 16.1%. A subsample analysis where information on maximal ventilation rate per employee was available revealed an effect for ventilation rate (adjusted odds ratio (AOR) 0.996, 95% CI 0.993-0.999). When including temperature as an interaction term in the working area, the effect of the ventilation rate did not change. Increasing room temperatures resulted in a lower chance of obtaining a positive COVID-19 test result (AOR 0.90 95% CI 0.82-0.99), and a 0.1% greater chance of a positive COVID-19 test for the interaction term (AOR 1.001, 95% CI 1.000-1.003). Our results further indicate that climate conditions and low outdoor air flow are factors that can promote the spread of SARS-CoV-2 aerosols. A possible requirement for pandemic mitigation strategies in industrial workplace settings is to increase the ventilation rate.

description: Η έννοια της ουσίας είναι μια βασική κατηγορία της Ευρωπαϊκής Μεταφυσικής η οποία υπέστη κριτική από τους οπαδούς του εμπειρισμού και πρώτα από όλους από τον J. Locke ο οποίος υπέθεσε ότι, πέρα από τις παραστάσεις των αισθήσεών μας υπάρχει μια υλική ουσία, πάνω στην οποία εδράζονται οι ποιότητες του πράγματος, στις οποίες αντιστοιχούν οι ιδέες και στις οποίες μεταφέρονται οι παραστάσεις των αισθήσεων μας. Ο G. Berkeley από την άλλη πρότεινε την πνευματική ουσία. Σύμφωνα με αυτόν, ο νους εντός του οποίου βρίσκονται οι ιδέες μας, δεν είναι επίσης μια ιδέα αλλά είναι η πνευματική ουσία, πάνω στην οποία οικοδομούνται οι ιδέες που σχηματίζουμε μέσω των αισθήσεών μας. Τέλος, ο D. Hume αμφισβήτησε την ύπαρξη τόσο της πνευματικής όσο και της υλικής ουσίας. Είναι λογικά ανεπίτρεπτο να υποθέτουμε την ύπαρξη μιας πνευματικής υπόστασης (ουσίας) μέσα μας και να μιλάμε για την ύπαρξη μιας πραγματικότητας έξω από μας. Στην παρούσα εργασία θα διερευνήσουμε την κριτική της έννοιας της ουσίας στις διάφορες εκδοχές της και θα προσπαθήσουμε να αναδείξουμε βασικές πτυχές της σχετικής προβληματικής.
description: The concept of substance is a basic category of European Metaphysics which underwent criticism from the supporters of empiricism and first of all from J. Locke who assumed that, beyond the representations of our senses there exists a material substance, that supports the qualities of a thing, to which correspond the ideas and to which are transfered the representations of our senses. G. Berkeley on the other hand proposed a mental substance. According to him, the mind inside which are found our ideas, is not also an idea but is the mental substance, on which are constructed the ideas that we form via our senses. Finally, D. Hume questioned the existence of a mental substance as well as of a material substance. It is logically impermissible to assume the existence of a mental substance in us and to speak of the existence of reality outside of us. In the present work we will investigate the criticism of the concept of substance in its various versions and we will try to set forth basic aspects relevant to the issue in questioning.
Time indexed formulation of scheduling problems

Publisher: name: University of British Columbia
Year: 2009

description: In this thesis, we study various approaches that could be used in finding a lower bound for single and parallel machine scheduling problems. These approaches are based on integer programming formulations involving binary variables indexed by (i,t), where i denotes a job and t is a time period. For the single machine case, we provide an approximation scheme and a Lagrangian relaxation procedure both of which produce good lower bounds. We also present a new column generation algorithm which solves the LP-relaxation of time-indexed formulation using fewer columns than the standard column generation procedure. In chapter 3 we present a new integer programming formulation for the movie scheduling problem, based on time indexed variables. This formulation led us to investigate the general parallel machine scheduling problem, for which we present a column generation procedure, which is an extension of the work done by van den Akker for the single machine case.

description: The detection of gamma-rays from the source HESS J1745-290 in the Galactic Center (GC) region with the H.E.S.S. array of Cherenkov telescopes in 2004 is presented. After subtraction of the diffuse gamma-ray emission from the GC ridge, the source is compatible with a point-source with spatial extent less than 1.2'(stat.) (95% CL). The measured energy spectrum above 160 GeV is compatible with a power-law with photon index of 2.25 +/- 0.04(stat.) +/- 0.10 (syst.) and no significant flux variation is detected. These measurements are discussed in the framework of dark matter annihilation. It is found that the bulk of the VHE emission must have non-dark-matter origin. Loose constraints on the velocity-weighted annihilation cross section are derived assuming the presence of an astrophysical non-dark-matter gamma-ray contribution.

description: Stellar photometry of nearby irregular galaxies of the Local Group is used to identify and study the young and old stellar populations of these galaxies. An analysis of the spatial distributions of stars of different ages in face-on galaxies shows that the young stellar populations in irregular galaxies are concentrated toward the center, and form local inhomogeneities in star-forming regions, while the old stellar populations--red giants--form extended structures around the irregular galaxies. The sizes of these structures exceed the visible sizes of the galaxies at the 25m/arcsec^2 isophote by a factor of two to three. The surface density of the red giants decreases exponentially from the center toward the edge, similar to the disk components in spiral galaxies.

description: Graphene is a recently discovered carbon based material with unique physical properties. This is a monolayer of graphite, and the two-dimensional electrons and holes in it are described by the effective Dirac equation with a vanishing effective mass. As a consequence, electromagnetic response of graphene is predicted to be strongly non-linear. We develop a quasi-classical kinetic theory of the non-linear electromagnetic response of graphene, taking into account the self-consistent-field effects. Response of the system to both harmonic and pulse excitation is considered. The frequency multiplication effect, resulting from the non-linearity of the electromagnetic response, is studied under realistic experimental conditions. The frequency up-conversion efficiency is analysed as a function of the applied electric field and parameters of the samples. Possible applications of graphene in terahertz electronics are discussed.

description: While dealing with a Hamiltonian with continuous spectrum we use a tridiagonal method involving orthogonal polynomials to construct a set of coherent states obeying a Glauber-type condition. We perform a Bayesian decomposition of the weight function of the orthogonality measure to show that the obtained coherent states can be recast in the Gazeau-Klauder approach. The Hamiltonian of the $\ell$-wave free particle is treated as an example to illustrate the method.

description: Understanding the formation and evolution of low surface brightness galaxies (LSBGs) is critical for explaining their wide-ranging properties. However, studies of LSBGs in deep photometric surveys are often hindered by a lack of distance estimates. In this work, we present a new catalogue of 479 LSBGs, identified in deep optical imaging data from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). These galaxies are found across a range of environments, from the field to groups. Many are likely to be ultra-diffuse galaxies (UDGs). We see clear evidence for a bimodal population in colour - Sérsic index space, and split our sample into red and blue LSBG populations. We estimate environmental densities for a subsample of 215 sources by statistically associating them with nearby spectroscopic galaxies from the overlapping GAMA spectroscopic survey. We find that the blue LSBGs are statistically consistent with being spatially randomised with respect to local spectroscopic galaxies, implying they exist predominantly in low-density environments. However, the red LSBG population is significantly spatially correlated with local structure. We find that 26+/-5% of isolated, local LSBGs belong to the red population, which we interpret as quiescent. This indicates that high environmental density plays a dominant, but not exclusive, role in producing quiescent LSBGs. Our analysis method may prove to be very useful given the large samples of LSB galaxies without distance information expected from e.g. the Vera C. Rubin observatory (aka LSST), especially in combination with upcoming comprehensive wide field spectroscopic surveys.

description: In this paper we compare two constructions of weight functions (off-shell Bethe vectors) for the quantum affine algebra $U_q(\hat{\mathfrak{gl}}_N)$. The first construction comes from the algebraic nested Bethe ansatz. The second one is defined in terms of certain projections of products of Drinfeld currents. We show that two constructions give the same result in tensor products of vector representations of $U_q(\hat{\mathfrak{gl}}_N)$.

description: Equational unification of two terms consists of finding a substitution that, when applied to both terms, makes them equal modulo some equational properties. A narrowing-based equational unification algorithm relying on the concept of the variants of a term is available in the most recent version of Maude, version 3.0, which provides quite sophisticated unification features. A variant of a term t is a pair consisting of a substitution sigma and the canonical form of tsigma. Variant-based unification is decidable when the equational theory satisfies the finite variant property. However, this unification procedure does not take into account constructor symbols and, thus, may compute many more unifiers than the necessary or may not be able to stop immediately. In this paper, we integrate the notion of constructor symbol into the variant-based unification algorithm. Our experiments on positive and negative unification problems show an impressive speedup.

description: Point defects in semiconductor crystals provide a means for carriers to recombine nonradiatively. This recombination process impacts the performance of devices. We present the Nonrad code that implements the first-principles approach of Alkauskas et al. [Phys. Rev. B 90, 075202 (2014)] for the evaluation of nonradiative capture coefficients based on a quantum-mechanical description of the capture process. An approach for evaluating electron-phonon coupling within the projector augmented wave formalism is presented. We also show that the common procedure of replacing Dirac delta functions with Gaussians can introduce errors into the resulting capture rate, and implement an alternative scheme to properly account for vibrational broadening. Lastly, we assess the accuracy of using an analytic approximation to the Sommerfeld parameter by comparing with direct numerical evaluation.

description: The main objective of this master thesis is to create an environment for simulation of wireless transmission of information to a number of moving vehicles, utilizing techniques from Intelligent Agents and Semantic Web. The measurements obtained from the simulation will be used to extract useful conclusions regarding the improvement the antennas have on the movement of the vehicles.Specifically, the program simulates an environment containing vehicles and information emission points (antennas), which transmit any information regarding traffic in specific streets. Provided that the vehicles are located inside the scope of the emission points, they receive information regarding traffic in the streets, then process it and finally follow the optimal path to their destination.

Year: 2015

description: The time-dependent advection-diffusion equation in two spatial dimensions for a metabolite undergoing capillary transport, flux into surrounding tissue, axial and radially diffusion, back flux into the capillary, and subsequent washout is solved using JSim. The model code is generated using the Modular Program Constructor (MPC). The center of mass of the retained metabolite is calculated as a time-dependent function of absolute radial distance from the center of the capillary and axial distance along the capillary.
Tracer washout from an organ is predicted from the tracer center of mass

Publisher: name: F1000Research

description: Washout of tracer from any two or three dimensional organ depends on the flow per gram of tissue and the location of the tracer in the tissue. However, whether the tracer was injected into the inflow or into the tissue at a selected location, whether there is counter-current exchange or not, the washout time course becomes mono-exponential. At this point the location of the center of mass, combined with the convection-diffusion-permeation conditions, determines the rate constant of the washout.
Investigating risk factors for internet gaming disorder: impulsivity, ADHD, behavioural inhibition / activation, weekly gameplay and inhibitory control
Creators: name: Shand, TA

description: The recent decision by the World Health Organization to recognise Gaming Disorder as a behavioural addiction requires a shift in research focus towards its predisposing factors and progression. The Interaction of Person-Affect-Cognition-Execution (I-PACE) model is an emerging theory to explain the onset of disordered gaming by examining interactions between predisposing factors, moderators, and mediators combined with reduced executive functioning. The current study aimed to examine associations between various risk factors for disordered gaming and the development of IGD symptoms. A sample of 113 participants (75.2% female, mean age 22.5 years) completed measures of internet gaming disorder (IGD), impulsivity, attention deficit hyperactivity disorder (ADHD), behavioural inhibition/activation (BIS/BAS) and weekly gameplay. A subsample of 30 participants (90.9% female, mean age 23.2 years) completed a combined Flanker/go-nogo task. In the first sample, impulsivity and weekly playtime significantly predicted IGD scores. In the second sample, IGD scores were not significantly associated with measures of inhibitory control deficits. This study supports previous findings that impulsivity and gaming time are significant risk factors for developing IGD symptoms. Future replication comparing groups with low and high IGD symptomology combined with neuroimaging may provide more substantial evidence for risk factors associated with the development of gaming addiction.

Παράλληλα, η συγγραφή φιλοδοξεί να υπηρετήσει και μία δεύτερη σκοπιμότητα: φωτίζοντας επιλεγμένα αριστοτελικά χωρία να αναδείξει τον μοναδικά επίκαιρο χαρακτήρα ορισμένων πτυχών της σκέψης του μεγάλου σοφού, που σε μία εποχή άκριτου και άκρατου καταναλωτισμού, πολιτικής ασυνέπειας λόγω και πράξεων μαζοποίησης και ισοπέδωσης των πάντων, δύναται να προσφέρει σωτήρια διέξοδο από φαινόμενα κοινωνικής παθογένειας.
description: The present work aims at offering all those explanatory keys that will lead the reader to a more complete comprehension of the significance of virtue to Aristotle, significance immediately interwoven-as it will be shown-with the human happiness(evdaimonia) and the good. At the same time the writing as gives to serve a second expediency: litting up selectively Aristotelian extracts it elects the unique topical character of certain aspects of the thought of this wise man and his ethical philosophy. In an era of an extreme and thoughtless consumenism, political inconsistency of reasons and action, his words offer a salvation exit from phenomena of social pathogeny.

description: Livestock husbandry practices and other management techniques can help prevent or reduce predation by coyotes, dogs, foxes, bears, bobcats, and mountain lions. Sheep and goats are considered most vulnerable to predators, although poultry, cattle, hogs, horses, and exotic game animals are often subject to predation in many areas of North America. This pamphlet deals primarily with protecting sheep and goats, but the information in it can be applied to other livestock as well.

description: Multi-layered scintillating fibre arrays read-out are commonly used as high resolution charged particle hodoscopes. Fibres of a column along the geometrical trajectory of incident particles are typically grouped to one pixel of a multi-channel read-out device. In some applications the incident particles will cross the detection plane with large angles w.r.t. the normal to the layers. Then, the packing of the fibres needs to be adapted to the incident particles and the columns need to be inclined. In this paper possible fibre array geometries are shown, relevant design criteria for detectors are discussed, and the effect of diverging particles incident on fibre arrays was studied using a Monte Carlo simulation.

description: Response-adaptive designs have been extensively studied and used in clinical trials. However, there is a lack of a comprehensive study of response-adaptive designs that include covariates, despite their importance in clinical experiments. Because the allocation scheme and the estimation of parameters are affected by both the responses and the covariates, covariate-adjusted response-adaptive (CARA) designs are very complex to formulate. In this paper, we overcome the technical hurdles and lay out a framework for general CARA designs for the allocation of subjects to $K (\geq 2)$ treatments. The asymptotic properties are studied under certain widely satisfied conditions. The proposed CARA designs can be applied to generalized linear models. Two important special cases, the linear model and the logistic regression model, are considered in detail.
Differential Viewpoints for Ground Terrain Material Recognition

description: Computational surface modeling that underlies material recognition has transitioned from reflectance modeling using in-lab controlled radiometric measurements to image-based representations based on internet-mined single-view images captured in the scene. We take a middle-ground approach for material recognition that takes advantage of both rich radiometric cues and flexible image capture. A key concept is differential angular imaging, where small angular variations in image capture enables angular-gradient features for an enhanced appearance representation that improves recognition. We build a large-scale material database, Ground Terrain in Outdoor Scenes (GTOS) database, to support ground terrain recognition for applications such as autonomous driving and robot navigation. The database consists of over 30,000 images covering 40 classes of outdoor ground terrain under varying weather and lighting conditions. We develop a novel approach for material recognition called texture-encoded angular network (TEAN) that combines deep encoding pooling of RGB information and differential angular images for angular-gradient features to fully leverage this large dataset. With this novel network architecture, we extract characteristics of materials encoded in the angular and spatial gradients of their appearance. Our results show that TEAN achieves recognition performance that surpasses single view performance and standard (non-differential/large-angle sampling) multiview performance.
