Algorithms for detecting and segmenting nucleated blood cells
Creators: name: Poon, Steven Sui-Sang
Publisher: name: University of British Columbia
Year: 2010

description: The analysis of the different types of cells in blood is routinely used in today's medical practice to give an indication of a person's state of health. Many imaging systems and algorithms have been developed over the last 30 years in an attempt to automate this process. Some of these systems can now distinguish the difference between normal and abnormal cells but the differentiation among the various types of abnormal cells is still undergoing active research. A new system, the Cell Analyzer Imaging System, has been developed to acquire and process images from a microscope. In this work, some new algorithms have been developed using this system to detect and segment nucleated cells in Wright's stained blood smears for classification and sub-classification of the normal and abnormal cell types. The initial steps are to obtain high quality images by greatly reducing noise as well as by correcting distortions, aberrations and shading effects present in the acquired images. Spectral information from the images is then utilized to detect and segment nucleated cells from the rest of the scene (non-nucleated cells and background). All nucleated cells as well as those which are just touching are selected and separated into individual cells. The resulting single cells are further segmented into the regions of nucleus and cytoplasm. Simple features are then extracted from the segmented cells and these features are compared to determine if any clustering of a particular class of cell exists. Results show that these algorithms can detect, segment and classify different types of normal and abnormal nucleated blood cells. The major errors in segmentation accounts for approximately 6% of the cells analyzed.

description: Recent observations of thermally emitting isolated neutron stars revealed spectral features that could be interpreted as radiative transitions of He in a magnetized neutron star atmosphere. We present Hartree-Fock calculations of the polarization-dependent photoionization cross sections of the He atom in strong magnetic fields ranging from 10^12 G to 10^14 G. Convenient fitting formulae for the cross sections are given as well as related oscillator strengths for various bound-bound transitions. The effects of finite nucleus mass on the radiative absorption cross sections are examined using perturbation theory.

description: Thin, viscous liquid films subjected to impact events can deform. Here we investigate free surface oil film deformations that arise due to the air pressure buildup under the impacting and rebouncing water drops. Using Digital Holographic Microscopy, we measure the 3D surface topography of the deformed film immediately after the drop rebound, with a resolution down to 20 nm. We first discuss how the film is initially deformed during impact, as a function of film thickness, film viscosity, and drop impact speed. Subsequently, we describe the slow relaxation process of the deformed film after the rebound. Scaling laws for the broadening of the width and the decay of the amplitude of the perturbations are obtained experimentally and found to be in excellent agreement with the results from a lubrication analysis. We finally arrive at a detailed spatio-temporal description of the oil film deformations that arise during the impact and rebouncing of water drops.

description: The Toda lattice is a model of nonlinear wave equations allowing exact soliton solutions. It is realized by an electric circuit made of a transmission line with variable capacitance diodes and inductors. It has been generalized to the dimerized Toda lattice by introducing alternating bondings specified by a certain parameter $λ$, where it is reduced to the Toda lattice at $λ=0$. In this work, we investigate the topological dynamics of the voltage along the transmission line. It is demonstrated numerically that the system is topological for $λ<0$, while it is trivial for $λ>0$ with the phase transition point given by the original Toda lattice ($λ=0$). These topological behaviors are well explained by the chiral index familiar in the Su-Schrieffer-Heeger model. The topological phase transition is observable by a significant difference between the dynamics of voltages in the two phases, which is explained by the emergence of the topological edge states. This is a bulk-edge correspondence in nonlinear systems. The dimerized Toda lattice is adiabaticaly connected to a linear system, which would be the reason why the topological arguments are valid. Furthermore, we show that the topological edge state is robust against randomness.

Anomalous-order exceptional point and non-Markovian Purcell effect at threshold in one-dimensional continuum systems

description: For a system consisting of a quantum emitter coupled near threshold (band edge) to a one-dimensional continuum with a van Hove singularity in the density of states, we demonstrate general conditions such that a characteristic triple level convergence occurs directly on the threshold as the coupling $g$ is shut off. For small $g$ values the eigenvalue and norm of each of these states can be expanded in a Puiseux expansion in terms of powers of $g^{2/3}$, which suggests the influence of a third-order exceptional point. However, in the actual $g \rightarrow 0$ limit, only two discrete states in fact coalesce as the system can be reduced to a $2 \times 2$ Jordan block; the third state instead merges with the continuum. Moreover, the decay width of the resonance state involved in this convergence is significantly enhanced compared to the usual Fermi golden rule, which is consistent with the Purcell effect. However, non-Markovian dynamics due to the branch-point effect are also enhanced near the threshold. Applying a perturbative analysis in terms of the Puiseux expansion that takes into account the threshold influence, we show that the combination of these effects results in quantum emitter decay of the unusual form $1 - C t^{3/2}$ on the key timescale during which most of the decay occurs. We then present two conditions that must be satisfied at the threshold for the anomalous exceptional point to occur: the density of states must contain an inverse square-root divergence and the potential must be non-singular. We further show that when the energy of the quantum emitter is detuned from threshold, the anomalous exceptional point splits into three ordinary exceptional points, two of which appear in the complex-extended parameter space. These results provide deeper insight into a well-known problem in spontaneous decay at a photonic band edge.

description: Jets in hadron collisions are very complicated with a long learning curve replete with errors. In relativistic heavy ion (RHI) collisions, it is likely that jets will be much more complicated with an even longer and more difficult learning curve. Hard scattering is more easily observed via single particle and few particle correlation measurements. The main advantage of jets is higher rate at large $p_T$, plus the possibility of detailed studies of soft fragmentation if the soft fragments can be separated from the background. A critical review of the possibility of using jets as a probe of hard-scattering in RHI collisions is presented along with other probes and measurements which the author considers much more likely to reveal the interesting physics in Pb+Pb collisions at the LHC. Finally, a list of unanswered questions raised by results at RHIC is presented.

description: Introduction : Comme le souligne Giasson (2012), la compréhension est le but de la lecture. Pourtant, cette auteure explique que les élèves passent du temps à apprendre à lire sur les textes très courts, puis passent très rapidement à des textes plus longs sans recevoir d’enseignement de la compréhension de texte. Cela peut créer des cercles vicieux comme on le voit avec l’effet Matthieu en lecture (Wren, et al. 2000). Les élèves plus compétents et ayant plus de plaisir à lire lisent plus, tandis que les élèves moins motivés lisent moins et progressent moins. Il est alors important d’agir le plus tôt possible au cours de la scolarité et d’enseigner la compréhension de texte. Méthode : il s’agit d’une recherche quasi-expérimentale menée auprès de huit élèves ayant des troubles du langage. Les élèves ont reçu un enseignement explicite de cinq stratégies en compréhension de texte : se former une image mentale, réaliser des inférences comme se mettre à la place d’un personnage et imaginer ce qu’il pense, réaliser des prédictions, réaliser des inférences causales et finalement l’autorégulation. L’intervention a eu lieu durant huit semaines, à raison d’une séance par semaine. Les compétences en compréhension de texte ont été évaluées avant et après l’intervention. Résultats et discussion : les compétences des élèves se sont globalement améliorées entre le pré-test et le post-test. De manière intéressante, les résultats montrent également que les élèves ayant un niveau de départ moins élevé font des progrès plus importants. Nous constatons qu’il est primordial d’enseigner ces stratégies de compréhension de texte à des élèves qui ne lisent pas encore de manière fluide et qui ont des difficultés de compréhension à l’oral ou à l’écrit. De plus, nous pouvons faire l’hypothèse que cela permettrait d’augmenter la motivation des élèves à lire ou à écouter des textes, afin qu’ils progressent plus et de créer ainsi des cercles vertueux.

description: We study the motion of dispersed nanoprobes in entangled active-passive polymer mixtures. By comparing the two architectures of linear vs. unconcatenated and unknotted circular polymers, we demonstrate that novel, rich physics emerge. For both polymer architectures, nanoprobes of size smaller than the entanglement threshold of the solution move faster as activity is increased and more energy is pumped in the system. For larger nanoprobes, a surprising phenomenon occurs: while in linear solutions they move qualitatively as before, in active-passive ring solutions nanoprobes {\it decelerate} with respect to the purely passive conditions. We rationalize this effect in terms of the non-equilibrium, topology-dependent association (clustering) of nanoprobes to the cold component of the ring mixture reminiscent of the recently discovered [Weber et al., Phys. Rev. Lett. 116, 058301 (2016)] phase separation in scalar active-passive mixtures. We conclude with a potential connection to the microrheology of the chromatin in the nuclei of the cells.

description: We present a detailed analysis of the Galaxy Stellar Mass Function of galaxies up to z=2.5 as obtained from the VVDS. We estimate the stellar mass from broad-band photometry using 2 different assumptions on the galaxy star formation history and show that the addition of secondary bursts to a continuous star formation history produces systematically higher (up to 40%) stellar masses. At low redshift (z=0.2) we find a substantial population of low-mass galaxies (<10^9 Msun) composed by faint blue galaxies (M_I-M_K=0.3). In general the stellar mass function evolves slowly up to z=0.9 and more significantly above this redshift. Conversely, a massive tail is present up to z=2.5 and have extremely red colours (M_I-M_K=0.7-0.8). We find a decline with redshift of the overall number density of galaxies for all masses (59+-5% for M>10^8 Msun at z=1), and a mild mass-dependent average evolution (`mass-downsizing'). In particular our data are consistent with mild/negligible (<30%) evolution up to z=0.7 for massive galaxies (>6x10^10 Msun). For less massive systems the no-evolution scenario is excluded. A large fraction (>=50%) of massive galaxies have been already assembled and converted most of their gas into stars at z=1, ruling out the `dry mergers' as the major mechanism of their assembly history below z=1. This fraction decreases to 33% at z=2. Low-mass systems have decreased continuously in number and mass density (by a factor up to 4) from the present age to z=2, consistently with a prolonged mass assembly also at z<1.

description: Motivated by recent theoretical work on tidal disruption events and other peculiar transients, we present moving-mesh radiation-hydrodynamic simulations of radiative luminosity emitted by a central source being reprocessed by a wind-like outflow. We couple the moving-mesh hydrodynamic code JET with our newly-developed radiation module based on mixed-frame grey flux-limited diffusion with implicit timestep update. This allows us to study the self-consistent multi-dimensional radiation-hydrodynamic evolution over more than ten orders of magnitude in both space and time in a single run. We simulate an optically-thick spherical wind with constant or evolving mass-loss rate, which is irradiated by a central isotropic or angularly-dependent radiation source. Our spherically-symmetric simulations confirm previous analytic results by identifying different stages of radiation reprocessing: radiation trapped in the wind, diffusing out through the wind, and reaching constant maximum attenuation. We find that confining the central radiation source in a cone with moderate opening angles decrease up to one order of magnitude the early flux along sightlines oriented away from the direction of radiation injection but that the reprocessed radiation becomes isotropic roughly after one lateral diffusion time through the ejecta. We discuss further applications and guidelines for the use of our novel radiation-hydrodynamics tool in the context of transient modelling.

description: This article deals with the discussion about a united Europe during the interwar period from 1918 to 1936. Therefore the author points out some sources that provide information about the role and point of view taken by the labour movement in this time period. Referring to discussions on Europeanisation the article underlines some arguments for example the economic competition between the United States of America and Europe, problems caused by multinational companies and increased mobility of capital. By comparison some of these arguments sound surprisingly similar to current debates about European integration. Concepts regarding market freedom, tariff reduction and cooperation between the French and German mining- and steel industry as well as problems like mass unemployment, labour mobility and wage policy in a united Europe have already been considered during that period.

VLSI implementable associative memory based on neural network architecture
Creators: name: Mok, Winston Ki-Cheong
Publisher: name: University of British Columbia
Year: 2010

description: Neural network associative memories based on Hopfield's design have two failure modes. 1) Certain memories are not recallable as they do not lie in a local minimum of the system's Liapunov (energy) function, and 2) the associative memory converges to a non-memory location due to trapping by spurious local minima in the energy function surface. The properties of the first failure mechanism in the Hopfield and five related models were investigated. A new architecture eliminating such failures is proposed. The architecture is fully digital and modular. Furthermore, it is more silicon-area efficient than any of the analyzed models. VLSI circuits built using this architecture will be able to contain a large number of neurons and several circuits may be connected together to further increase capacity.

description: In this thesis, I examine a case study of liturgical originality in the Orthodox Church, four anonymous texts that form a noteworthy contribution to the liturgical debate. From 1997 to 2012, four such texts have been anonymously published by the Athenian theological publishing house Domos, proposing to the Church a new wedding ceremony, a new baptismal service, a new funeral service and a new divine liturgy. These form a now complete group of texts, and comprise the ‘New Ecclesiastical Service of the Mystery of Marriage, composed and offered to the Church by a certain unnamed married man‘ (2007), the ‘New Ecclesiastical Service for those who have fallen asleep, composed and offered to the Church by a certain one unnamed of those who have been left behind’ (2008), the ‘New Ecclesiastical Service of the Mystery of Baptism, composed and offered to the Church by a certain one unnamed of those who have been baptised’ (2012) and ‘The Ecclesial Eucharist in Need of Contemporary Rewriting’ (2012). This thesis comprises a systematic encounter with the theological proposal that these services constitute, as well as an analysis of certain aspects of their author’s theological corpus (Christos Yannaras, as becomes apparent in the thesis).

description: ELIXIR is an intergovernmental organization that brings together life science resources across Europe. These resources include databases, software tools, training materials, cloud storage, and supercomputers. One of the goals of ELIXIR is to coordinate these resources so that they form a single infrastructure. This infrastructure makes it easier for scientists to find and share data, exchange expertise, and agree on best practices. ELIXIR's activities are divided into the following five areas Data, Tools, Interoperability, Compute and Training known as “platforms”. The ELIXIR Tools Platform works to improve the discovery, quality and sustainability of software resources. Software Best Practices task of the Tools Platform aims to raise the quality and sustainability of research software by producing, adopting, promoting and measuring information standards and best practices applied to the software development life cycle. We have published four (4OSS) simple recommendations to encourage best practices in research software and the Top 10 metrics for life science software good practices. The next step is to adopt, promote, and recognise these information standards and best practices, by developing comprehensive guidelines for software curation, and through workshops for training researchers and developers towards the adoption of software best practices.

description: Asteroseismic measurements enable inferences of the underlying stellar structure, such as the density and the speed of sound at various points within the interior of the star. This provides an opportunity to test stellar evolution theory by assessing whether the predicted structure of a star agrees with the measured structure. Thus far, this kind of inverse analysis has only been applied to the Sun and three solar-like main-sequence stars. Here we extend the technique to stars on the subgiant branch, and apply it to one of the best-characterized subgiants of the Kepler mission, HR 7322. The observation of mixed oscillation modes in this star facilitates inferences of the conditions of its inert helium core, nuclear-burning hydrogen shell, and the deeper parts of its radiative envelope. We find that despite significant differences in the mode frequencies, the structure near to the center of this star does not differ significantly from the predicted structure.

description: The thermal plasma of galaxy clusters lost most of its information on how structure formation proceeded as a result of dissipative processes. In contrast, non-equilibrium distributions of cosmic rays (CR) preserve the information about their injection and transport processes and provide thus a unique window of current and past structure formation processes. This information can be unveiled by observations of non-thermal radiative processes, including radio synchrotron, hard X-ray, and gamma-ray emission. To explore this, we use high-resolution simulations of a sample of galaxy clusters spanning a mass range of about two orders of magnitudes, and follow self-consistent CR physics on top of the radiative hydrodynamics. We model CR electrons that are accelerated at cosmological structure formation shocks and those that are produced in hadronic interactions of CRs with ambient gas protons. We find that CR protons trace the time integrated non-equilibrium activities of clusters while shock-accelerated CR electrons probe current accretion and merging shock waves. The resulting inhomogeneous synchrotron emission matches the properties of observed radio relics. We propose a unified model for the generation of radio halos. Giant radio halos are dominated in the centre by secondary synchrotron emission with a transition to the synchrotron radiation emitted from shock-accelerated electrons in the cluster periphery. This model is able to explain the observed correlation of mergers with radio halos, the larger peripheral variation of the spectral index, and the large scatter in the scaling relation between cluster mass and synchrotron emission. Future low-frequency radio telescopes (LOFAR, GMRT, MWA, LWA) are expected to probe the accretion shocks of clusters. [abridged]

description: We consider a two-dimensional (2D) nonlinear Schrodinger equation with self-focusing nonlinearity and a quasi-1D double-channel potential, i.e., a straightforward 2D extension of the well-known double-well potential. The model may be realized in terms of nonlinear optics and Bose-Einstein condensates. The variational approximation (VA) predicts a bifurcation breaking the symmetry of 2D solitons trapped in the double channel, the bifurcation being of the subcritical type. The predictions of the VA are confirmed by numerical simulations. The work presents the first example of the spontaneous symmetry breaking (SSB) of 2D solitons in any dual-core system.

description: Reynolds-averaged Navier-Stokes (RANS) is one of the most cost-efficient approaches to simulate wind-farm-atmosphere interactions. However, the applicability of RANS-based methods is always limited by the accuracy of turbulence closure models, which introduce various uncertainties into the models. In this study, we estimate model-form uncertainties in RANS simulations of wind farms. For this purpose, we compare different RANS models to a large-eddy simulation (LES). We find that the realizable k-epsilon model is a representative RANS model for predicting the mean velocity, the turbulence intensity, and the power losses within the wind farm. We then investigate the model-form uncertainty associated with this turbulence model by perturbing the Reynolds stress tensor. The focus is placed on perturbing the shape of the tensor represented by its eigenvalues. The results show that the perturbed RANS model successfully estimates the region bounding the LES results for quantities of interest (QoIs). We also discuss the effect of perturbation magnitude on various QoIs.

description: Topological defects are one of the most conspicuous features of liquid crystals. In two dimensional nematics, they have been shown to behave effectively as particles with both, charge and orientation, which dictate their interactions. Here, we study "twisted" defects that have a radially dependent orientation. We find that twist can be partially relaxed through the creation and annihilation of defect pairs. By solving the equations for defect motion and calculating the forces on defects, we identify four distinct elements that govern the relative relaxational motion of interacting topological defects, namely attraction, repulsion, co-rotation and co-translation. The interaction of these effects can lead to intricate defect trajectories, which can be controlled by setting relevant timescales.

Στα πλαίσια της έρευνας αυτής αναζητήθηκαν, αποκλειστικά μέσα στα έργα του Παλαμά, οι προϋποθέσεις του ορθώς και κατά Θεόν θεολογείν, ώστε να διαπιστώσει τη σχέση μεταξύ της διανοητικής, στοχαστικής, θεολογίας και της εμπειρικής Θεολογίας, αυτής δηλαδή που προκύπτει όχι από την προσπάθεια του ανθρώπου να στοχαστεί περί Θεού αλλά από την αποκάλυψη του ίδιου του Θεού μέσα στο άνθρωπο.
description: St. Gregory Palamas, with his overall writings, sums up the ecclesiastical Christian experience from the earliest Christian epochs to the time, showing continuously the importance of the unity of faith and life in the expression of theology. In the context of this research, in the works of Palamas alone, the terms of the right and against the Gods are theological, in order to establish the relationship between the spiritual, theoretical and empirical theology, that is, not resulting from the human effort to understand the God but to reveal Himself to God in man.

description: Linear polarization in X- and gamma-rays is an important diagnostic of many astrophysical sources, foremost giving information about their geometry, magnetic fields, and radiation mechanisms. However, very few X-ray polarization measurements have been made, and then only mono-energetic detections, whilst several objects are assumed to have energy dependent polarization signatures. In this paper we investigate whether detection of energy dependent polarization from cosmic sources is possible using the Compton technique, in particular with the proposed PoGOLite balloon-experiment, in the 25-100 keV range. We use Geant4 simulations of a PoGOLite model and input photon spectra based on Cygnus X-1 and accreting magnetic pulsars (100 mCrab). Effective observing times of 6 and 35 hours were simulated, corresponding to a standard and a long duration flight respectively. Both smooth and sharp energy variations of the polarization are investigated and compared to constant polarization signals using chi-square statistics. We can reject constant polarization, with energy, for the Cygnus X-1 spectrum (in the hard state), if the reflected component is assumed to be completely polarized, whereas the distinction cannot be made for weaker polarization. For the accreting pulsar, constant polarization can be rejected in the case of polarization in a narrow energy band with at least 50% polarization, and similarly for a negative step distribution from 30% to 0% polarization.

A decreased probability of habitable planet formation around low-mass stars

description: Smaller terrestrial planets (< 0.3 Earth masses) are less likely to retain the substantial atmospheres and ongoing tectonic activity probably required to support life. A key element in determining if sufficiently massive "sustainably habitable" planets can form is the availability of solid planet-forming material. We use dynamical simulations of terrestrial planet formation from planetary embryos and simple scaling arguments to explore the implications of correlations between terrestrial planet mass, disk mass, and the mass of the parent star. We assume that the protoplanetary disk mass scales with stellar mass as Mdisk ~ f Mstar^h, where f measures the relative disk mass, and 1/2 < h < 2, so that disk mass decreases with decreasing stellar mass. We consider systems without Jovian planets, based on current models and observations for M stars. We assume the mass of a planet formed in some annulus of a disk with given parameters is proportional to the disk mass in that annulus, and show with a suite of simulations of late-stage accretion that the adopted prescription is surprisingly accurate. Our results suggest that the fraction of systems with sufficient disk mass to form > 0.3 Earth mass habitable planets decreases for low-mass stars for every realistic combination of parameters. This "habitable fraction" is small for stellar masses below a mass in the interval 0.5 to 0.8 Solar masses, depending on disk parameters, an interval that excludes most M stars. Radial mixing and therefore water delivery are inefficient in lower-mass disks commonly found around low-mass stars, such that terrestrial planets in the habitable zones of most low-mass stars are likely to be small and dry.

Baryon Number-Induced Chern-Simons Couplings of Vector and Axial-Vector Mesons in Holographic QCD

description: We show that holographic models of QCD predict the presence of a Chern-Simons coupling between vector and axial-vector mesons at finite baryon density. In the AdS/CFT dictionary, the coefficient of this coupling is proportional to the baryon number density, and is fixed uniquely in the five-dimensional holographic dual by anomalies in the flavor currents. For the lightest mesons, the coupling mixes transverse $ρ$ and $a_1$ polarization states. At sufficiently large baryon number densities, it produces an instability, which causes the $ρ$ and $a_1$ mesons to condense in a state breaking both rotational and translational invariance.

description: In this work we show that is possible to obtain Total Quantum Zeno Effect in an unstable systems for times larger than the correlation time of the bath. The effect is observed for some particular systems in which one can chose appropriate observables which frequent measurements freeze the system into the initial state. For a two level system in a squeezed bath one can show that there are two bath dependent observables displaying Total Zeno Effect when the system is initialized in some particular states. We show also that these states are intelligent states of two conjugate observables associated to the electromagnetic fluctuations of the bath.

description: Mérimée était écrivain, archéologue, historien, linguiste, traducteur, antiquisant, médiéviste, hispanisant, slavisant... Pourtant, c'est le conteur qui intéressa presque exclusivement les commentateurs jusqu'au centenaire de sa mort qui inaugura, en 1970, trente ans d'indifférence. De là, une situation de table rase, propice au renouveau des études mériméennes, comme en témoigne la création, en 2009, des Cahiers Mérimée, une revue ouverte à des études d'orientation et de discipline diverses.

description: The simulation of dense fermionic matters is a long-standing problem in lattice gauge theory. One hopeful solution would be the use of quantum computers. In this paper, digital quantum simulation is designed for lattice gauge theory at nonzero density. The quantum variational algorithm is adopted to obtain the ground state at nonzero density. A benchmark test is performed in the lattice Schwinger model.
Asteroseismic Signatures of Stellar Magnetic Activity Cycles

description: Observations of stellar activity cycles provide an opportunity to study magnetic dynamos under many different physical conditions. Space-based asteroseismology missions will soon yield useful constraints on the interior conditions that nurture such magnetic cycles, and will be sensitive enough to detect shifts in the oscillation frequencies due to the magnetic variations. We derive a method for predicting these shifts from changes in the Mg II activity index by scaling from solar data. We demonstrate this technique on the solar-type subgiant beta Hyi, using archival International Ultraviolet Explorer spectra and two epochs of ground-based asteroseismic observations. We find qualitative evidence of the expected frequency shifts and predict the optimal timing for future asteroseismic observations of this star.
