description: In classical estimation theory, the central limit theorem implies that the statistical error in a measurement outcome can be reduced by an amount proportional to n^(-1/2) by repeating the measures n times and then averaging. Using quantum effects, such as entanglement, it is often possible to do better, decreasing the error by an amount proportional to 1/n. Quantum metrology is the study of those quantum techniques that allow one to gain advantages over purely classical approaches. In this review, we analyze some of the most promising recent developments in this research field. Specifically, we deal with the developments of the theory and point out some of the new experiments. Then we look at one of the main new trends of the field, the analysis of how the theory must take into account the presence of noise and experimental imperfections.

description: In the existing literature, there are really a few reaseach works describing such population-based incidences of ocular tumors as crude, age-adjusted and standardized incidences, mortality and survival rates that range widely in different studies and often contradicts each other. Moreover, there are few studies of relationship between ocular tumors and geographic zones and the influence of contaminaited soil, water or air on the incidence and mortality of patients with ocular tumors. This book brings together various classifications of benign and malignant ocular tumors in children and adults in Chapter 1, which is very convenient for their use by clinicians. The remaining two chapters are devoted to the epidemiological aspects of ocular tumors compares with epidemiological studies in Uzbekistan, where such researches was conducted for the first time and based on the own experience and author’s publications. The book is of interest to ophthalmologists, oncologists, pediatricians, epidemiologists, ecologists, senior students of medical universities, as well as to a wide audience of specialists interesed in the influence of the enviroment on the development of tumor of the eyes.

description: The proliferation of commercial cloud computing providers has generated significant interest in the scientific computing community. Much recent research has attempted to determine the benefits and drawbacks of cloud computing for scientific applications. Although clouds have many attractive features, such as virtualization, on-demand provisioning, and "pay as you go" usage-based pricing, it is not clear whether they are able to deliver the performance required for scientific applications at a reasonable price. In this paper we examine the performance and cost of clouds from the perspective of scientific workflow applications. We use three characteristic workflows to compare the performance of a commercial cloud with that of a typical HPC system, and we analyze the various costs associated with running those workflows in the cloud. We find that the performance of clouds is not unreasonable given the hardware resources provided, and that performance comparable to HPC systems can be achieved given similar resources. We also find that the cost of running workflows on a commercial cloud can be reduced by storing data in the cloud rather than transferring it from outside.

description: We present the results of an automated variability analysis of the Kepler public data measured in the first quarter (Q1) of the mission. In total, about 150 000 light curves have been analysed to detect stellar variability, and to identify new members of known variability classes. We also focus on the detection of variables present in eclipsing binary systems, given the important constraints on stellar fundamental parameters they can provide. The methodology we use here is based on the automated variability classification pipeline which was previously developed for and applied successfully to the CoRoT exofield database and to the limited subset of a few thousand Kepler asteroseismology light curves. We use a Fourier decomposition of the light curves to describe their variability behaviour and use the resulting parameters to perform a supervised classification. Several improvements have been made, including a separate extractor method to detect the presence of eclipses when other variability is present in the light curves. We also included two new variability classes compared to previous work: variables showing signs of rotational modulation and of activity. Statistics are given on the number of variables and the number of good candidates per class. A comparison is made with results obtained for the CoRoT exoplanet data. We present some special discoveries, including variable stars in eclipsing binary systems. Many new candidate non-radial pulsators are found, mainly Delta Sct and Gamma Dor stars. We have studied those samples in more detail by using 2MASS colours. The full classification results are made available as an online catalogue.

description: Temperature-dependent inter-plane resistivity, $ρ_c(T)$, was measured systematically as a function of transition metal substitution in the iron-arsenide superconductors Ba(Fe$_{1-x}$T$_x$)$_2$As$_2$, $T$= Ni, Pd, Rh. The data are compared with the behavior found in Ba(Fe$_{1-x}$Co$_x$)$_2$As$_2$, revealing resistive signatures of pseudogap. In all compounds we find resistivity crossover at a characteristic pseudogap temperature $T^*$ from non-metallic to metallic temperature dependence on cooling. Suppression of $T^*$ proceeds very similar in cases of Ni and Pd doping and much faster than in similar cases of Co and Rh doping. In cases of Co and Rh doping an additional minimum in the temperature-dependent $ρ_c$ emerges for high dopings, when superconductivity is completely suppressed. These features are consistent with the existence of a charge gap covering part of the Fermi surface. The part of the Fermi surface affected by this gap is notably larger for Ni and Pd doped compositions than in Co and Rh doped compounds.

description: Using a generalized parton model approach including spin and intrinsic parton motion effects, and assuming the validity of factorization for large-pT jet production in hadronic collisions, we study the azimuthal distribution around the jet axis of leading unpolarized or (pseudo)scalar hadrons, namely pions, produced in the jet fragmentation process. We identify the observable leading-twist azimuthal asymmetries for the unpolarized and single-polarized case related to quark and gluon-originated jets. We account for all physically allowed combinations of the transverse momentum dependent (TMD) parton distribution and fragmentation functions, with special attention to the Sivers, Boer-Mulders, and transversity quark distributions, and to the Collins fragmentation function for quarks (and to the analogous functions for gluons). For each of these effects we evaluate, at central and forward rapidities and for kinematical configurations accessible at BNL-RHIC, the corresponding potentially maximized asymmetry (for pi+ production), obtained by saturating natural positivity bounds (and the Soffer bound for transversity) for the distribution and fragmentation functions involved and summing additively all partonic contributions. We then estimate, for both neutral and charged pions, the asymmetries involving TMD functions for which parameterizations are available. We also study the role of the different mechanisms, and the corresponding transverse single spin asymmetries, for large-pT inclusive jet production.

Automatic translucency detection of basal cell carcinoma (BCC) via deep learning methods
Creators: name: Huang, He
Publisher: name: University of British Columbia
Year: 2018

description: Translucency, defined as a jelly-like appearance, is a common clinical feature of basal cell carcinoma (BCC), the most common skin cancer. This feature plays an important role in diagnosing basal cell carcinoma at an early stage because the translucency can be observed readily in clinical examinations with a high specificity. Therefore, translucency detection is a critical component of computer aided systems which aim at early detection of basal cell carcinoma. In this thesis, we proposed two deep learning methods to automatically detect translucency. First, we develop a convolutional neural network based framework to detect translucency of basal cell carcinoma. Furthermore, a sparse auto-encoder based framework is proposed for translucency detection on BCC images. Since currently two types of skin images are mainly used for diagnosis of basal cell carcinoma by doctors, which are dermoscopy images and clinical images, we evaluate two proposed methods on both types of skin images. Our results showed that the two proposed methods yield similar detection performances. For detecting translucency in dermoscopy images, both proposed methods achieve comparable accuracy results, though the accuracy is not as good as we expected. For detecting translucency in clinical images, both methods achieve good performances. Compared the performances in both types of images, the proposed deep learning based methods seems more suitable for translucency detection in clinical images than in dermoscopy images.

description: Colloidal particles that are confined to an interface effectively form a two-dimensional fluid. We examine the dynamics of such colloids when they are subject to a constant external force, which drives them in a particular direction over the surface. Such a situation occurs, for example, for colloidal particles that have settled to the bottom of their container, when the container is tilted at an angle, so that they `sediment' to the lower edge of the surface. We focus in particular on the case when there are attractive forces between the colloids which causes them to phase separate into regions of high density and low density and we study the influence of this phase separation on the sedimentation process. We model the colloids as Brownian particles and use both Brownian dynamics computer simulations and dynamical density functional theory (DDFT) to obtain the time evolution of the ensemble average one-body density profiles of the colloids. We consider situations where the external potential varies only in one direction so that the ensemble average density profiles vary only in this direction. We solve the DDFT in one-dimension, by assuming that the density profile only varies in one direction. However, we also solve the DDFT in two-dimensions, allowing the fluid density profile to vary in both the $x$- and $y$-directions. We find that in certain situations the two-dimensional DDFT is clearly superior to its one-dimensional counterpart when compared with the simulations and we discuss this issue.

description: The dynamic properties of membranes have been object of many researches since they can be used as sensor heads in different devices. Some methods have been proposed to solve the problem of determining the resonance frequencies and their dependence on the stress caused by forces applied on the membrane surface. The problem of the vibrating rectangular membrane under a stress caused by a uniform in-plane force is well known. However, the resonance frequency behaviour when the force is out-of-plane instead of in-plane, is not so well understood and documented. A gradiometer which uses a silicon square membrane with a magnet fixed on it as a sensor head has been developed in a previous work. This device reports a quadratic dependence of the frequency on the out-of-plane magnetic force. In this work, simulations to obtain the dependence of the frequency of the fundamental flexural mode on the stress have been performed. It has been studied the influence of in-plane and out-of-plane forces applied to the membrane. As expected, a square root dependence has been found for in-plane forces. Nevertheless, the problem is more complex when out-of plane forces are considered. Out-of-plane forces gives rise to an initial quadratic dependence which turns into a square root dependence from a certain stress value. The quadratic range increases and the rate of change of the frequency decreases as the surface of the magnet fixed on the membrane increases. The study has addressed these problems and both, experimental and simulated results have been compared and a good agreement between experimental and simulated results has been found

Radiation Hydrodynamics in Solar Flares

Year: 2010
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Solar flares are currently understood as the explosive release of energy stored in the form of stressed magnetic fields. In many cases, the released energy seems to take the form of large numbers of electrons accelerated to high energies or alternatively plasma heated to very high temperatures. The transport of this energy into the remaining portion of the atmosphere results in violent mass motion and strong emission across the electromagnetic spectrum. One important phenomenon observed during flares is the appearance in coronal magnetic loops of large amounts of upflowing, soft X-ray emitting plasma. It is believed that this is due to chromospheric evaporation, the process of heating cool chromospheric material beyond its ability to radiate. The pressure increase in the evaporated plasma leads to a number of interesting phenomena in the flare chromosphere. The sudden pressure increase initiates a downward moving "chromospheric condensation", an overdense region which gradually decelerates as it accretes material and propagates into the gravitationally stratified chromosphere. Solutions to an equation of motion for this condensation shows that its motion decays after about one minute of propagation into the chromosphere. When the front of this downflowing region is supersonic relative to the atmosphere ahead of it, a radiating shock will form. If the downflow is rapid enough, the shock strength should be sufficient to excite UV radiation normally associated with the transition region, and furthermore, the radiating shock will be brighter than the transition region. These results lead to a number of observationally testable relationships between the optical and ultraviolet spectra from the condensation and radiating shock.

Vertices with an arbitrary number of both background and quantum legs can be derived automatically from both gluonic and fermionic actions. The algorithm is a generalisation of our earlier algorithm based on prior work by Lüscher and Weisz. We also present techniques allowing for the parallelisation of the evaluation of the often rather complex lattice Feynman rules that should allow for efficient implementation on GPUs, but also give a significant speed-up when calculating the derivatives of Feynman diagrams with respect to external momenta.

Planning for whom? The practice of cultural inclusion in alternative food initiatives in Metro Vancouver
Creators: name: Ostenso, Victoria
Publisher: name: University of British Columbia
Year: 2018

description: As part of a social movement to challenge and transform the dominant agrifood system, alternative food initiatives (AFIs) strive to create more socially and environmentally just food systems through policy change and programming. In a culturally plural context, processes need to be in place to ensure change efforts consider the perspectives and priorities of individuals from diverse backgrounds, including from diverse racial, cultural, and ethnic backgrounds. This thesis calls attention to the approaches and outcomes of AFIs towards cultural inclusion and racial justice through two case studies. The first is an analysis of the approaches to cultural inclusion by four food policy councils in Metro Vancouver. The second takes a closer look at one AFI, the Richmond community garden program, to better understand how garden participants navigate and benefit from the convergence of difference in public gardens. Through interviews, participant observation, and document analysis this thesis exposes the complexity of shifting towards culturally inclusive practice and provides key learnings for AFI practitioners as they strive towards more culturally inclusive outcomes in their own context.

description: The protein C is a small viral protein encoded in an overlapping frame of the P gene in the subfamily Orthoparamyxovirinae. This protein, expressed by alternative translation initiation, is a virulence factor that regulates viral transcription, replication, and production of defective interfering RNA, interferes with the host-cell innate immunity systems and supports the assembly of viral particles and budding. We expressed and purified full-length and an N-terminally truncated C protein from Tupaia paramyxovirus (TupV) C protein (genus Narmovirus). We solved the crystal structure of the C-terminal part of TupV C protein at a resolution of 2.4 Å and found that it is structurally similar to Sendai virus C protein, suggesting that despite undetectable sequence conservation, these proteins are homologous. We characterized both truncated and full-length proteins by SEC-MALLS and SEC-SAXS and described their solution structures by ensemble models. We established a mini-replicon assay for the related Nipah virus (NiV) and showed that TupV C inhibited the expression of NiV minigenome in a concentration-dependent manner as efficiently as the NiV C protein. A previous study found that the Orthoparamyxovirinae C proteins form two clusters without detectable sequence similarity, raising the question of whether they were homologous or instead had originated independently. Since TupV C and SeV C are representatives of these two clusters, our discovery that they have a similar structure indicates that all Orthoparamyxovirine C proteins are homologous. Our results also imply that, strikingly, a STAT1-binding site is encoded by exactly the same RNA region of the P/C gene across Paramyxovirinae, but in different reading frames (P or C), depending on which cluster they belong to.

description: The longer-term impacts of the COVID-19 pandemic on the European food supply chain may be substantially different than the short-term adaptation of farmers, food processors and retailers. The main consumer preference changes are likely to be linked to greater on-line ordering, home delivery and in-home consumption. The food industry changes will probably be more persistent and of greater magnitude than those on the consumer side, including a preference for production and processing closer to consumption, and greater flexibility in processing. The COVID-19 pandemic will promote greater automation throughout the food chain with automation of combinable crops leading the way because the engineering is more tractable than for fruits and vegetables. The COVID-19 pandemic will lead to a re-emphasis on food production and food security in agricultural policy throughout Europe. That re-emphasis of food security will be strongest in those countries which saw the largest and longest disruption in consumer level food availability. The COVID-19 pandemic has disrupted the European food system, but in the longer run it could also create opportunities for those ready to adapt to the changing realities.

description: Context. Radial velocity monitoring of very cool dwarfs such as late M- and hot L-dwarfs has become a promising tool to search for rocky planets as well as to follow-up planetary candidates around dwarfs found by transit surveys. These stars are faint at optical wavelengths, as their spectral flux distribution peaks at near-infrared (NIR) wavelengths. For this reason, it is desirable to measure the radial velocities in this wavelength regime. However, in the NIR there are only very few medium- and high-resolution spectrographs available which are mounted at large telescopes. In the near future, high-resolution spectrographs for the NIR will be built, which will allow us to search for rocky planets around cool M-dwarfs and L-dwarfs from radial velocities monitoring. Methods. Stellar atmosphere synthetic models for an M- and an L-dwarf with temperatures of 2200 K and 1800 K, respectively, and a theoretical spectrum of the Earth's transmission in the spectral range from 0.9 to 2.5 \mum are used. We simulate a series of Doppler-shifted spectra observed with different resolving powers and signal-to-noise ratios, and for different rotational broadenings of the dwarf. For different combinations of the input parameters we recover the radial velocity by means of cross-correlation with a high signal-to-noise ratio template and determine the associate uncertainties. Results. The highest precision in radial velocity measurements for the cool M-dwarf is found in the Y band around 1.0 \mum, while for the L-dwarf it is determined in the J band around 1.25 \mum. We note that synthetic models may lack of some faint absorption features or underestimate their abundances. Conversely, some instrumental/calibration aspects that are not taken into account in our estimations would rise the uncertainties.

description: We develop a unified model of hadrons and quarks. Within this approach we investigate the phase structure of the model as function of temperature and chemical potential. Computing the equation of state of cold matter we determine neutron and hybrid star masses and radii. In an extension of the investigation we consider the cooling behavior of the compact stars and derive a general relation between the star's mass and rotation and its cooling behavior. Finally we study the effect of Delta resonances for star matter, especially with respect to possible solutions of stars with small radii.

description: We review the developments in modeling gravitational recoil from merging black-hole binaries and introduce a new set of 20 simulations to test our previously proposed empirical formula for the recoil. The configurations are chosen to represent generic binaries with unequal masses and precessing spins. Results of these simulations indicate that the recoil formula is accurate to within a few km/s in the similar mass-ratio regime for the out-of-plane recoil.

description: Clialina similis n. sp. Trois spécimens. Cette espèce ressemble beaucoup à Chalina limbata et à G. finitima par sa couleur pâle, sa texture fibreuse, sa consistance compressible, souple et élastique. Comme elles, elle possède un tissu conjonctif formé de files de cellules sphéruleuses qui produisent chacune un ligament élastique. Sa charpente se dispose en réseau à mailles rectangulaires et larges. Ses fibres sont surtout composées de spongine; les primaires, uni, bi ou trispiculées, ont 60 [a de diamètre, les secondaires, unispiculées, en mesurent 16 à 40. A en juger par deux des spécimens de la collection, Clialina similis a plus de tendance que C. limbata à devenir massive. L'un d'eux, dressé sur le support, est cylindrique, haut de 18 mm., avec 6-8 mm. de diamètre. La surface est lisse; les oscilles, larges, simples ou composés, s'ouvrent au sommet des lobes. Je n'ai pas découvert de gemmules à la base. C'est par les dimensions de ses spicules, surtout par leur épaisseur, que Chalina similis se distingue le mieux des espèces précitées. Ses oxes, presque droits, à pointes acérées courtes, mesurent, en effet, 4^ d'épaisseur pour une longueur de 80 ^ seulement.

description: We study the power-aware buffering problem in battery-powered sensor networks, focusing on the fixed-size and fixed-interval buffering schemes. The main motivation is to address the yet poorly understood size variation-induced effect on power-aware buffering schemes. Our theoretical analysis elucidates the fundamental differences between the fixed-size and fixed-interval buffering schemes in the presence of data size variation. It shows that data size variation has detrimental effects on the power expenditure of the fixed-size buffering in general, and reveals that the size variation induced effects can be either mitigated by a positive skewness or promoted by a negative skewness in size distribution. By contrast, the fixed-interval buffering scheme has an obvious advantage of being eminently immune to the data-size variation. Hence the fixed-interval buffering scheme is a risk-averse strategy for its robustness in a variety of operational environments. In addition, based on the fixed-interval buffering scheme, we establish the power consumption relationship between child nodes and parent node in a static data collection tree, and give an in-depth analysis of the impact of child bandwidth distribution on parent's power consumption. This study is of practical significance: it sheds new light on the relationship among power consumption of buffering schemes, power parameters of radio module and memory bank, data arrival rate and data size variation, thereby providing well-informed guidance in determining an optimal buffer size (interval) to maximize the operational lifespan of sensor networks.

description: We study phenomenological consequences of the Standard Model extension by the new spin-1 chiral fields with the internal quantum numbers of the electroweak Higgs doublets. There are at least three different classes of theories, all motivated by the hierarchy problem, which predict new vector weak-doublets with masses not far from the electro-weak scale. We discuss resonance production of these neutral chiral Z* bosons at hadron colliders. The bosons can be observed as a Breit-Wigner resonance peak in the invariant dilepton mass distributions in the same way as the well-known extra gauge Z' bosons. This includes them into a list of very interesting objects for early searches with the first LHC data. Moreover, the Z* bosons have unique signatures in transverse momentum, angular and pseudorapidity distributions of the final leptons, which allow to distinguish them from the other heavy neutral resonances.

description: The work examines graphene doped with nitrogen. Alloying characteristics are considered. The research tool chosen is density functional theory (DFT), implemented using the ABINIT code. At the first stage, a graphene alloy is studied. Next, the main alloying structures are considered. According to DFT calculations, nitrogen is adsorbed on the surface of the graphene sheet. Calculation of activation barriers proves that nitrogen can be included in the headspace (blank). In the process of studying the interaction of adsorbed nitrogen and the gap, it turns out that the free space attracts adsorbed nitrogen. Initial calculations show that inclusion of the K point of the first Brillouin zone reduces the energy of the doped structures. This reduction may be misestimated when momentum space is sparsely sampled.
