description: We compare an analytic model of jet quenching, based on the GLV non-Abelian energy loss formalism, to numerical results for the centrality dependent suppression of hadron cross sections in Au+Au and Cu+Cu collisions at RHIC. Simulations of neutral pion quenching versus the size of the colliding nuclear system are presented to high transverse momentum pT. At low and moderate pT, we study the contribution of medium-induced gluon bremsstrahlung to single inclusive hadron production. In Pb+Pb collisions at the LHC, the redistribution of the lost energy is shown to play a critical role in yielding nuclear suppression that does not violate the participant scaling limit.

description: The presence of massive black holes (BHs) with masses of order $10^9\rm\, M_\odot$, powering bright quasars when the Universe was less than 1 Gyr old, poses strong constraints on their formation mechanism. Several scenarios have been proposed to date to explain massive BH formation, from the low-mass seed BH remnants of the first generation of stars to the massive seed BHs resulting from the rapid collapse of massive gas clouds. However, the plausibility of some of these scenarios to occur within the progenitors of high-z quasars has not yet been thoroughly explored. In this work, we investigate, by combining dark-matter only N-body simulations with a semi-analytic framework, whether the conditions for the formation of massive seed BHs from synchronised atomic-cooling halo pairs and/or dynamically-heated mini-haloes are fulfilled in the overdense regions where the progenitors of a typical high-redshift quasar host form and evolve. Our analysis shows that the peculiar conditions in such regions, i.e. strong halo clustering and high star formation rates, are crucial to produce a non-negligible number of massive seed BH host candidates: we find $\approx1400$ dynamically heated metal-free mini-haloes, including one of these which evolves to a synchronised pair and ends up in the massive quasar-host halo by $z=6$. This demonstrates that the progenitors of high-redshift quasar host haloes can harbour early massive seed BHs. Our results further suggest that multiple massive seed BHs may form in or near the quasar host's progenitors, potentially merging at lower redshifts and yielding gravitational wave events.

description: We propose a minimal model that can explain the electroweak scale, neutrino masses, Dark Matter (DM), and successful inflation all at once based on the multicritical-point principle (MPP). The model has two singlet scalar fields that realize an analogue of the Coleman-Weinberg mechanism, in addition to the Standard Model with heavy Majorana right-handed neutrinos. By assuming a $Z_2 $ symmetry, one of the scalars becomes a DM candidate whose property is almost the same as the minimal Higgs-portal scalar DM. In this model, the MPP can naturally realize a saddle point in the Higgs potential at high energy scales. By the renormalization-group analysis, we study the critical Higgs inflation with non-minimal coupling $ξ|H|^2 R$ that utilizes the saddle point of the Higgs potential. We find that it is possible to realize successful inflation even for $ξ=25$ and that the heaviest right-handed neutrino is predicted to have a mass around $10^{14}$ GeV to meet the current cosmological observations. Such a small value of $ξ$ can be realized by the Higgs-portal coupling $λ_{SH}\simeq 0.32$ and the vacuum expectation value of the additional neutral scalar $\langleϕ\rangle\simeq 2.7$ TeV, which correspond to the dark matter mass 2.0 TeV, its spin-independent cross section $1.8\times10^{-9}$ pb, and the mass of additional neutral scalar 190 GeV.

description: Agronomical characters such as yield, biotic and abiotic resistance are determined by the genetic information carried by the plant genome. Within the framework of the International Wheat Genome Sequencing Initiative (IWGSC) effort for obtaining a reference sequence of the bread wheat genome and to provide the scientific communities dealing with large and complex genomes a versatile, easy-to-use online annotation tool, we have developed the TriAnnot pipeline (Leroy et al. 2012). TriAnnot has already been used to annotate the wheat chromosome 3B (Choulet et al. 2014) and 4D (Helguera et al. 2015). Annotation of chromosome 1B is currently underway (INRA – GDEC), as well as the annotation of chromosome 7A in collaboration with the University of Murdoch (Australia). TriAnnot has the ambition to federate the international community around the annotation of the 21 wheat chromosomes and, in this perspective, the TriAnnot source code has been strongly improved to facilitate its deployment on external computing resources such as: IEB, Olomouc (Czech Republic); The Pawsey Supercomputing Centre, WA (Australia); National Research Council of Canada, Saskatoon (Canada); CRRI, Clermont-Ferrand and ABiMS CNRS bioinformatics platform, Roscoff (France). The development of a virtual machine is also underway in collaboration with ABiMS and the French Institute of bioinformatics (IFB). TriAnnot was also adapted for the annotation of other plant genomes such as barley, maize, rice and oak. A public instance of TriAnnot is currently deployed on the cluster of the URGI bioinformatics platform (Versailles) and usable through a user-friendly web interface or in command line.
A Sketching Framework for Reduced Data Transfer in Photon Counting Lidar

description: Single-photon lidar has become a prominent tool for depth imaging in recent years. At the core of the technique, the depth of a target is measured by constructing a histogram of time delays between emitted light pulses and detected photon arrivals. A major data processing bottleneck arises on the device when either the number of photons per pixel is large or the resolution of the time stamp is fine, as both the space requirement and the complexity of the image reconstruction algorithms scale with these parameters. We solve this limiting bottleneck of existing lidar techniques by sampling the characteristic function of the time of flight (ToF) model to build a compressive statistic, a so-called sketch of the time delay distribution, which is sufficient to infer the spatial distance and intensity of the object. The size of the sketch scales with the degrees of freedom of the ToF model (number of objects) and not, fundamentally, with the number of photons or the time stamp resolution. Moreover, the sketch is highly amenable for on-chip online processing. We show theoretically that the loss of information for compression is controlled and the mean squared error of the inference quickly converges towards the optimal Cramér-Rao bound (i.e. no loss of information) for modest sketch sizes. The proposed compressed single-photon lidar framework is tested and evaluated on real life datasets of complex scenes where it is shown that a compression rate of up-to 150 is achievable in practice without sacrificing the overall resolution of the reconstructed image.

description: Amorphous chalcogenide thin film deposition can be achieved by a spin-coating technique from proper solutions of the corresponding glass. Films produced in this way exhibit certain grain texture, which is presumably related to the cluster size in solution. This paper deals with the search of such a correlation between grain size of surface morphology of as-deposited spin-coated As33S67 chalcogenide thin films and cluster size of the glass in butylamine solutions. Optical absorption spectroscopy and dynamic light scattering were employed to study optical properties and cluster size distributions in the solutions at various glass concentrations. Atomic force microscopy is used to study the surface morphology of the surface of as-deposited and thermally stabilized spin-coated films. Dynamic light scattering revealed a concentration dependence of cluster size in solution. Spectral-dependence dynamic light scattering studies showed an interesting athermal photo-aggregation effect in the liquid state.

Variations on a Theme by Massey

description: In 1994, Jim Massey proposed the guessing entropy as a measure of the difficulty that an attacker has to guess a secret used in a cryptographic system, and established a well-known inequality between entropy and guessing entropy. Over 15 years before, in an unpublished work, he also established a well-known inequality for the entropy of an integer-valued random variable of given variance. In this paper, we establish a link between the two works by Massey in the more general framework of the relationship between discrete (absolute) entropy and continuous (differential) entropy. Two approaches are given in which the discrete entropy (or Rényi entropy) of an integer-valued variable can be upper bounded using the differential (Rényi) entropy of some suitably chosen continuous random variable. As an application, lower bounds on guessing entropy and guessing moments are derived in terms of entropy or Rényi entropy (without side information) and conditional entropy or Arimoto conditional entropy (when side information is available).

description: The purpose of the present study was to examine the nature of the discourse generated by two different online approaches to mathematics teacher professional development. Thirty mathematics teachers participated in online activities involving analysis and discourse about artifacts of teaching practice. Half were randomly assigned to a group that analyzed and discussed students work samples, and the other half to a group focused upon descriptions of classroom teaching episodes. Teachers formed threads of conversation on asynchronous discussion boards as they considered the different aspects of each artifact. Within the threads, different orientations toward the reform agenda in mathematics education were shown. Some messages were strongly rooted in the reform paradigm, others in the traditional paradigm, and many others contained elements characteristic of each paradigm. The distribution and characteristics of the messages reflected teachers’ frequent attempts to try to reconcile the largely incompatible paradigms undergirding reform-oriented and traditional approaches to mathematics instruction. This paper describes the nature of the discourses occurring within each group of teachers with the aim of providing empirical grounds to inform the actions of teacher educators and researchers designing online learning environments that attempt to bring teachers more fully into the reform-oriented discourse about teaching mathematics.

description: We present a photometric and structural analysis of 42 E/S0 galaxies in (E/S0 + S) pairs observed in the BVRI color bands. We empirically determine the effects of interactions on their morphology, structure and stellar populations as seen from the light concentration (C), asymmetry (A), and clumpiness (S) parameters. We further compare these values to a control sample of 67 mostly isolated, non-interacting E/S0 galaxies. The paired E/S0 galaxies occupy a more scattered loci in CAS space than non-interacting E/S0's, and the structural effects of interactions on E/S0's are minor, in contrast to disk galaxies involved in interactions. This suggests that observational methods for recognizing interactions at high z, such the CAS methodology, would hardly detect E/S0's involved in interactions (related to early phases of the so called `dry-mergers'). We however find statistical differences in A when comparing isolated and interacting E/S0s. In the mean, paired E/S0 galaxies have A values 2.96+-0.72 times larger than the ones of non-interacting E/S0's. For the subset of presumably strongly interacting E/S0's, A and S can be several times larger than the typical values of the isolated E/S0's. We show that the asymmetries are consistent with several internal and external morphological distortions. We conclude that the interacting E/S0s in pairs should be dense, gas poor galaxies in systems spaning a wide range of interaction stages, with typical merging timescales >~ 0.1-0.5 Gyr. We use the observed phenomenology of these galaxies to predict the approximate loci of `dry pre-mergers' in the CAS space.(Abridged)

description: We propose a novel numerical method for high dimensional Hamilton--Jacobi--Bellman (HJB) type elliptic partial differential equations (PDEs). The HJB PDEs, reformulated as optimal control problems, are tackled by the actor-critic framework inspired by reinforcement learning, based on neural network parametrization of the value and control functions. Within the actor-critic framework, we employ a policy gradient approach to improve the control, while for the value function, we derive a variance reduced least-squares temporal difference method using stochastic calculus. To numerically discretize the stochastic control problem, we employ an adaptive step size scheme to improve the accuracy near the domain boundary. Numerical examples up to $20$ spatial dimensions including the linear quadratic regulators, the stochastic Van der Pol oscillators, the diffusive Eikonal equations, and fully nonlinear elliptic PDEs derived from a regulator problem are presented to validate the effectiveness of our proposed method.

description: Employing the random matrix formulation of Chern-Simons theory on Seifert manifolds, we show how the Stieltjes-Wigert orthogonal polynomials are useful in exact computations in Chern-Simons matrix models. We construct a biorthogonal extension of the Stieltjes-Wigert polynomials, not available in the literature, necessary to study Chern-Simons matrix models when the geometry is a lens space. We also discuss several other results based on the properties of the polynomials: the equivalence between the Stieltjes-Wigert matrix model and the discrete model that appears in q-2D Yang-Mills and the relationship with Rogers-Szego polynomials and the corresponding equivalence with an unitary matrix model. Finally, we also give a detailed proof of a result that relates quantum dimensions with averages of Schur polynomials in the Stieltjes-Wigert ensemble.

Application of project information models to Computer-integrated Construction
Creators: name: Yu, Kevin Qiang
Publisher: name: University of British Columbia
Year: 2009

description: Architecture, engineering and construction (AEC) projects are becoming increasingly complex. This complexity is manifested in the diversity and fragmentation of the construction projects. Computer-integrated Construction (CIC) offers ever-increasing potential to improve project management practice for AEC projects in resolving the fragmentation problem of construction information using computers (Froese 94d). CIC, however, must rely on the AEC project information being shared among various AEC computer applications used by many different project participants. This information sharing is based on the development of AEC information models (Froese 94b, 94c). In this thesis, we have proposed a set of AEC information models, the AEC Core Reference Models (ACRM). The ACRM have been developed based on our investigation of currently available AEC information models and on our own opinions of the desirable characteristics of the models. While the current development of the models is still in a conceptual stage, we believe that some basic central concepts are sufficiently well developed for testing some of their implementation capabilities in a computer program using a real-world example (Froese and Yu 94). In this research, we have developed a computer program, StartPlan, based on the ACRM. StartPlan provides a test-bed for these experiments. Since generic concepts such as Activity are defined in the ACRM, StartPlan can represent a wide range of AEC project information and allow the information to be shared and translated between different types of AEC computer applications. A fictitious construction project originally developed in REPCON (Russell 95) has been used in StartPlan for the test. Although it is not a specific real-world project, it can be treated as a typical project because it has been tested in many real-world situations and proven to contain most of the information that a similar real-world project would have. The results from the test reveal specific advantages and disadvantages of the proposed ACRM.

Non-LTE Monte Carlo Radiative Transfer: II. Non-Isothermal Solutions for Viscous Keplerian Disks

description: We discuss the basic hydrodynamics that determines the density structure of the disks around hot stars. Observational evidence supports the idea that these disks are Keplerian (rotationally supported) gaseous disks. A popular scenario in the literature, which naturally leads to the formation of Keplerian disks, is the viscous decretion model. According to this scenario, the disks are hydrostatically supported in the vertical direction, while the radial structure is governed by the viscous transport. This suggests that the temperature is one primary factor that governs the disk density structure. In a previous study we demonstrated, using 3-D NLTE Monte Carlo simulations, that viscous keplerian disks can be highly non-isothermal. In this paper we build upon our previous work and solve the full problem of the steady-state non-isothermal viscous diffusion and vertical hydrostatic equilibrium. We find that the self-consistent solution departs significantly from the analytic isothermal density, with potentially large effects on the emergent spectrum. This implies that non-isothermal disk models must be used for a detailed modeling of Be star disks.

description: We present our results on the electromagnetic form factor of pion over a wide range of $Q^2$ using lattice QCD simulations with Wilson-clover valence quarks and HISQ sea quarks. We study the form factor at the physical point with a lattice spacing $a=0.076$ fm. To study the lattice spacing and quark mass effects, we also present results for 300 MeV pion at two different lattice spacings $a=0.04$ and 0.06 fm. The lattice calculations at the physical quark mass appear to agree with the experimental results. Through fits to the form factor, we estimate the charge radius of pion for physical pion mass to be $\langle r_π^2 \rangle=0.42(2)~{\rm fm}^2$.

description: We relate structurally dynamic cellular networks, a class of models we developed in fundamental space-time physics, to SDCA, introduced some time ago by Ilachinski and Halpern. We emphasize the crucial property of a non-linear interaction of network geometry with the matter degrees of freedom in order to emulate the supposedly highly erratic and strongly fluctuating space-time structure on the Planck scale. We then embark on a detailed numerical analysis of various large scale characteristics of several classes of models in order to understand what will happen if some sort of macroscopic or continuum limit is performed. Of particular relevance in this context is a notion of network dimension and its behavior in this limit. Furthermore, the possibility of phase transitions is discussed.

description: Despite the fact that a variety of factors or "batch effects" can contribute unwanted variation to the data, commonly used RNA-seq normalization methods only correct for sequencing depth. The study of gene expression is particularly problematic when it is influenced simultaneously by a variety of biological factors in addition to the one of interest. Using examples from experimental neuroscience, we show that batch effects often dominate the signal of interest; and that the choice of normalization method affects the power and reproducibility of the results. We focus on one particular method, RUVSeq and show that it is able to increase power and biological insight of the results.

description: Over half of all temperate and tropical forested areas have been classified as regenerating, young secondary forests. These areas are important reservoirs of biodiversity and significant sources of timber and non-timber products. Studies exist that examine patterns in richness and shifts in traits through succession but less is known about changes in functional diversity as forests age. We examined changes in forest structure, plant species richness, and plant functional traits. In addition, we estimated rarified multi-trait functional diversity to deconstruct the individual and interactive effects of forest structure, species richness, and functional trait variation. Our results suggest that forest structure and species diversity in the lowlands of New Guinea changed in predictable ways during succession with increasing stem density and species density. Patterns of plant functional traits through succession suggest a shift in life-history strategy from resource acquisition to resource conservation as forests age. Even after accounting for differences in species and stem diversity, functional diversity increased as forests age.

description: The aim of this master thesis is the presentation of the Splitting Theorem, which was published by Alan Weinstein on his paper “The Local Structure of Poisson Manifolds” in 1983. The theorem states that locally every Poisson manifold is the direct product of a symplectic manifold with another Poisson manifold whose Poisson tensor vanishes at a point. In this way, we arrive at one of the most important global properties of a Poisson manifold, known as the symplectic foliation, which is its partition into symplectic sumbmanifolds. Basic tools from differential geometry are exploited, starting off with a brief introduction to symplectic manifolds. Focusing on to the more general notion of Poisson manifolds, we define some of their basic tools and investigate several of their characteristics. Results are given, followed by examples, being necessary to comprehend the main theorem.

description: Η εργασία επιχειρεί να ερευνήσει τις κύριες πτυχές της ποινικής ευθύνης από αμέλεια των μαιευτήρων – γυναικολόγων. Στόχος της είναι να παρουσιαστούν οι απόψεις της ποινικής θεωρίας για τα βασικά ζητήματα ιατρικής αμέλειας και να δοθεί μία εικόνα των αποφάσεων των ποινικών δικαστηρίων της χώρας, όταν κατηγορούμενος είναι ιατρός μαιευτήρας-γυναικολόγος. Παράλληλα παρουσιάζεται ένα περίγραμμα της δράσης του μαιευτήρα-γυναικολόγου από ιατρική σκοπιά, ώστε να καταδειχθεί ποιες πτυχές αυτού του ιατρικού έργου απασχολούν την ποινική νομολογία ως υποθέσεις ιατρικής αμέλειας. Τέλος, επιχειρείται μία συγκριτική προσέγγιση στην έννοια και στην εφαρμογή του ομοτεχνιακού ελέγχου, που μπορεί να συμβάλει ακόμη και στην πρόληψη των ιατρικών λαθών και έτσι και της ίδιας της ανάγκης εφαρμογής του ποινικού δικαίου, με αναφορά μεν στη Μαιευτική-Γυναικολογία αλλά οπωσδήποτε γενικότερου ενδιαφέροντος στην άσκηση της Ιατρικής.
description: The present thesis deals with the fundamental aspects of the criminal liability of gynecologists, who are proven negligent in the performance of their duties. Its aim is to analytically present the thesis expressed in the criminal dogma literature about the key issues of medical negligence and give an insight into the relevant case law with emphasis added to special cases of gynecologists brought before the criminal judge. Also an outline of the action of obstetrician-gynecologist from a medical standpoint is also presented, in order to establish which aspects of this medical malpractice are legally crucial. Finally, a comparative approach to the concept and application of “peer review” is also presented, with a further examination of its potential contribution to the prevention of medical errors and thus the very need for the application of criminal law.

description: We have obtained UBVRI images with the Kitt Peak and Cerro Tololo 4-m telescopes and Mosaic cameras of seven dwarfs in (or near) the Local Group, all of which have known evidence of recent star formation: IC10, NGC 6822, WLM, Sextans B, Sextans A, Pegasus,and Phoenix. We construct color-magnitude diagrams (CMDs) of these systems, as well as neighboring regions that can be used to evaluate the degree of foreground contamination by stars in the Milky Way. Inter-comparison of these CMDs with those of M31, M33, the LMC, and the SMC permits us to determine improved reddening values for a typical OB star found within these galaxies. All of the CMDs reveal a strong or modest number of blue supergiants. All but Pegasus and Phoenix also show the clear presence of red supergiants in the CMD, although IC10 appears to be deficient in these objects given its large WR population. The bright stars of intermediate color in the CMD are badly contaminated by foreground stars (30-100%), and considerable spectroscopy is needed before statistics on the yellow supergiants in these systems will be known. This study is intended to serve both as the impetus and "finding charts" for further space-based imaging, and for many spectroscopic programs at large aperture.

description: Simple dynamical models can produce intricate behaviors in large networks. These behaviors can often be observed in a wide variety of physical systems captured by the network of interactions. Here we describe a phenomenon where the increase of dimensions self-consistently generates a force field due to dynamical instabilities. This can be understood as an unstable ("rumbling") tunneling mechanism between minima in an effective potential. We dub this collective and nonperturbative effect a "Lyapunov force" which steers the system towards the global minimum of the potential function, even if the full system has a constellation of equilibrium points growing exponentially with the system size. The system we study has a simple mapping to a flow network, equivalent to current-driven memristors. The mechanism is appealing for its physical relevance in nanoscale physics, and to possible applications in optimization, novel Monte Carlo schemes and machine learning.

Dynamic behavioir of base cracked gravity dam by the way of the hybrid frequency time domain procedure
Creators: name: Hui, Pak K.
Publisher: name: University of British Columbia
Year: 2009

description: Due to deterioration, past loading conditions, and shrinkage, concrete tensile cracks may form along the dam-foundation interface within a typical concrete gravity dam monolith. These cracks render the assumption that a dam remains linear elastic during dynamic response invalid and requires a nonlinear analysis procedure. In this research, the response of the cracked dam system with the effects of a flexible foundation and hydrodynamic effects is studied using the Hybrid Frequency Time Domain (HFTD) analysis procedure. This nonlinear dynamic analysis procedure preserves the frequency dependent stiffness and damping in the foundation medium when modeled as a visco-elastic halfplane. Similarly, the HFTD procedure honours the frequency dependent hydrodynamic mass and damping of the reservoir medium when the hydrodynamic effects are modeled with a two dimensional wave equation. The nonlinear behavior of the crack opening and closing process is directly accounted for by applying the required restoring or contact force along the crack interface. The result of the study shows that dams with crack lengths less than 25% of the total base length have nominal differences in both magnitude and frequency of vibration when compared to the same uncracked system. For crack lengths in excess of 25%, larger response amplifications than those from the uncracked response were observed. The fundamental effective system frequency of vibration of the cracked dam system is found to be bounded by fundamental frequencies of the uncracked and cracked pseudo-linear systems of the dam. Large amplifications of the maximum dam top response obtained from the cracked system in comparison to the uncracked system are expected for systems near the dominant frequency of excitation. However, for systems with properties that are far removed from the dominant frequency of excitation, little, if any, amplification of the peak response is evident for all crack lengths. A simplified approach of representing the cracked dam system as a SDOF system with bi-linear stiffness proves to be an efficient and accurate method of estimating the cracked dam displacement and velocity response. The speed of the procedure allows for preliminary assessments to be made prior to dedicating valuable time to a full nonlinear analysis. In addition, this procedure can be used to produce cracked response spectra which can accurately predict the amplifications expected in the maximum relative displacement and velocity in a cracked dam system as compared to an uncracked dam system.

description: As part of an ongoing program to map better the empirical instability strip of pulsating ZZ Ceti white dwarfs, we present a brief progress report based on our last observing season. We discuss here high-speed photometric measurements for 6 new pulsators. These stars were selected on the basis of preliminary measurements of their effective temperature and surface gravity that placed them inside or near the known ZZ Ceti instability strip. We also report detection limits for a number of DA white dwarfs that showed no sign of variability. Finally, we revisit the ZZ Ceti star G232-38 for which we obtained improved high-speed photometry.

description: An unfocused plenoptic light field (LF) camera places an array of microlenses in front of an image sensor in order to separately capture different directional rays arriving at an image pixel. Using a conventional Bayer pattern, data captured at each pixel is a single color component (R, G or B).The sensed data then undergoes demosaicking (interpolation of RGB components per pixel) and conversion to an array of sub-aperture images (SAIs). In this paper, we propose a new LF image coding scheme based on graph lifting transform (GLT), where the acquired sensor data are coded in the original captured form without pre-processing. Specifically, we directly map raw sensed color data to the SAIs, resulting in sparsely distributed color pixels on 2D grids, and perform demosaicking at the receiver after decoding. To exploit spatial correlation among the sparse pixels, we propose a novel intra-prediction scheme, where the prediction kernel is determined according to the local gradient estimated from already coded neighboring pixel blocks. We then connect the pixels by forming a graph, modeling the prediction residuals statistically as a Gaussian Markov Random Field (GMRF). The optimal edge weights are computed via a graph learning method using a set of training SAIs. The residual data is encoded via low-complexity GLT. Experiments show that at high PSNRs -- important for archiving and instant storage scenarios -- our method outperformed significantly a conventional light field image coding scheme with demosaicking followed by High Efficiency Video Coding (HEVC).
