description: We present an analytical description of the energetics of the population of cosmic accretion shocks, for a concordance cosmology. We calculate how the shock-processed accretion power and mass current are distributed among different shock Mach numbers, and how they evolve with cosmic time. We calculate the cumulative energy input of cosmic accretion shocks of any Mach number to the intergalactic medium as a function of redshift, and we compare it with the energy output of supernova explosions as well as with the energy input required to reionize the universe. In addition, we investigate and quantify the effect of environmental factors, such as local clustering properties and filament preheating on the statistical properties of these shocks. We find that the energy processed by accretion shocks is higher than the supernova energy output for z<3 and that it becomes more than an order of magnitude higher in the local universe. The energy processed by accretion shocks alone becomes comparable to the energy required to reionize the universe by z~3.5. Finally, we establish both qualitative and quantitatively that both local clustering as well as filament compression and preheating are important factors in determining the statistical properties of the cosmic accretion shock population.

description: We calculate the gravitational self force acting on a pointlike particle of mass $μ$, set in a circular geodesic orbit around a Schwarzschild black hole. Our calculation is done in the Lorenz gauge: For given orbital radius, we first solve directly for the Lorenz-gauge metric perturbation using numerical evolution in the time domain; We then compute the (finite) back-reaction force from each of the multipole modes of the perturbation; Finally, we apply the ``mode sum'' method to obtain the total, physical self force. The {\em temporal} component of the self force (which is gauge invariant) describes the dissipation of orbital energy through gravitational radiation. Our results for this component are consistent, to within the computational accuracy, with the total flux of gravitational-wave energy radiated to infinity and through the event horizon. The {\em radial} component of the self force (which is gauge dependent) is calculated here for the first time. It describes a conservative shift in the orbital parameters away from their geodesic values. We thus obtain the $O(μ)$ correction to the specific energy and angular momentum parameters (in the Lorenz gauge), as well as the $O(μ)$ shift in the orbital frequency (which is gauge invariant).

description: Exegesis. The exegesis argues that contemporary women writers continue to find inspiration in the fairy tale, drawing on its form, themes, characters, symbolism and motifs to tell new stories. In particular, the exegesis claims that writers turn to the fairy tale for three broad purposes, two of which are contradictory, thereby suggesting the elasticity of the fairy tale as a structure. Firstly, fairy tales are used normatively, as a means of providing a structure that preserves traditional values, roles and politics (supporting the status quo). Secondly, fairy tales are used subversively to provide a structure that challenges ideas and assumptions around traditional values, usually associated with gender (subverting the status quo). And, thirdly, fairy tales are used as a structural formula, framework or technical tool to enhance characterisation, mood, atmosphere and meaning. The exegesis examines the way three writers, A.S. Byatt, Mercedes Lackey and Francesca Block employ Hans Christian Andersen's ""The Snow Queen"" as a framework for their fiction. Finally, I subject my own novel, ""Cold Vision"", to the same analysis, aiming to articulate the ideas and knowledge that were symbolically or indirectly expressed in the story, decoding the novel and exposing its themes and symbolism to discussion. Novel. When Evon Carr was a child, she believed in the power of her dreams. When her mother dies from cancer, Evon believes her dreams are responsible and vows never to dream again. As an adult, Evon works as a compliance officer for the Department of Immigration and Citizenship where she has learnt to be completely rational. She performs her duties with inhuman objectivity, remaining untouched by the human tragedy that she witnesses. Life starts to change for Evon on the day that her team raids a brothel and she detains an African healer dubbed "Mr Lucky", a man who never speaks. Instead, he gives Evon beads from his hair. Each bead unlocks a memory that takes Evon on a journey back to her childhood. With the help of her immigration team leader, Daniel Bell, Evon's unsympathetic approach to the people she encounters begins to change. When a woman commits suicide while being deported, Evon is forced to reconsider her hard-line approach to immigration enforcement and to come to terms with her own past. She returns to Mr Lucky, takes the last bead from him, and accepts her own guilt for her mother's death. Finally, she is able to dream again.

description: As the first step of the restoration process of painted relics, sketch extraction plays an important role in cultural research. However, sketch extraction suffers from serious disease corrosion, which results in broken lines and noise. To overcome these problems, we propose a deep learning-based hierarchical sketch extraction framework for painted cultural relics. We design the sketch extraction process into two stages: coarse extraction and fine extraction. In the coarse extraction stage, we develop a novel detail-aware bi-directional cascade network that integrates flow-based difference-of-Gaussians (FDoG) edge detection and a bi-directional cascade network (BDCN) under a transfer learning framework. It not only uses the pre-trained strategy to extenuate the requirements of large datasets for deep network training but also guides the network to learn the detail characteristics by the prior knowledge from FDoG. For the fine extraction stage, we design a new multiscale U-Net (MSU-Net) to effectively remove disease noise and refine the sketch. Specifically, all the features extracted from multiple intermediate layers in the decoder of MSU-Net are fused for sketch predication. Experimental results showed that the proposed method outperforms the other seven state-of-the-art methods in terms of visual and quantitative metrics and can also deal with complex backgrounds.
A study of procedures to examine correlation pattern hypotheses under conditions of multivariate normality and nonnormality
Creators: name: Fouladi, Rachel Tanya
Publisher: name: University of British Columbia
Year: 2009

description: A wide array of procedures have been proposed for testing correlation pattern. Many, but not all, of the statistical techniques available for testing correlation pattern are derived under the distributional condition of multivariate normality which does not always hold in the behavioral, educational and social sciences. Though a number of studies have explored the performance of structure analysis techniques under conditions of multivariate nonnormality, very little is known about the actual performance of many correlation structure analysis techniques under conditions of multivariate nonnormality. In addition, very little is known about the actual concurrent performance of tests of multivariate normality. The present investigation ascertains how tests of correlation pattern hypotheses and indicators of multivariate normality perform when data are from multivariate normal or nonnormal parent populations. This paper reviews and examines, using a Monte Carlo simulation study, the concurrent performance of different approaches to testing (1) correlation pattern hypotheses, including, (i) normal theory (NT) and asymptotically distribution free (ADF) covariance structure analysis techniques, (ii) NT and ADF correlation structure analysis techniques, (iii) correlation pattern specific techniques; (2) the distributional assumption of multivariate normality using statistics based on Mardia's measures of multivariate skewness and kurtosis. This paper also examines the performance characteristics of test procedures based on joint consideration of tests of multivariate normality and structure analysis techniques. Performance of the covariance and correlation structure analysis techniques, tests of multivariate normality, and joint test procedures was assessed across different types of correlation pattern models, numbers of variables, levels of skew and kurtosis, sample sizes, and nominal alpha levels, on the primary Neyman-Pearson criterion for an optimal test, according to which an optimal procedure (1) controls experimentwise Type I error rate at or below the nominal level, (2) maximizes power.
Synthetic studies of antibiotic natural products

description: The work detailed in this thesis is directed towards the synthesis of natural products exhibiting antibiotic activity. In antibiotics, we have a readily available means to treat bacterial infection, yet bacterial resistance is increasingly limiting the effectiveness of antibiotics in the clinical setting. With the number of new antibiotics released on the market each year in steady decline, investigation into novel structures that possess potential as antibiotics is urgently needed. Chapter 1 contextualises the serious problem of antibiotic resistance and how it can be addressed. Approaches for development of new antibiotics are examined, with particular focus on the central role of natural products as lead compounds, as well as the contributions made by total syntheses. In chapter 2, recent research into the tetramic acid family of natural products is reviewed. These compounds have been shown to exhibit a diverse array of biological activities including antibiotic, antifungal, anti-HIV and anticancer. Particular attention is paid to the discovery of new structures of this family, our understanding of these structures, as well as the development of novel pathways for their synthesis. One such tetramic acid natural product, ravenic acid (2), inspired our synthetic work involving the preparation of a number of tetramic acid analogues, which is detailed in chapter 3. Our interest in the synthesis of ravenic acid stemmed from our involvement in the isolation and structural assignment of this molecule. We targeted a number of structurally related analogues of ravenic acid, to allow for structural determination a co-metabolite, which was of interest due to its potential as an antibiotic. Two pathways were pursued for the synthesis of the targeted tetramic acid analogues, with our efforts resulting in the identification of a new, highly unsaturated, tetramic acid natural product (69), structurally related to the known natural product, ravenic acid. Another group of natural products that we targeted for total synthesis were the xanthoquinodins (chapter 4). The novel structural features of these molecules, as well their diverse biological activity, and the lack of other synthetic attempts towards their preparation prompted our synthetic investigations. In this chapter we describe our retrosynthetic analysis and evolution of a synthetic strategy, with the primary goal of the research the synthesis of three molecules, representing subunits of the xanthoquinodins. The realisation of this goal required exhaustive trialling of various pathways for their preparation. Preliminary model studies towards the linking of the three subunits are also reported.

description: We obtained medium-resolution spectra of 336 quasar candidates in the COSMOS HST/Treasury field using the MMT 6.5-meter telescope and the Hectospec multi-object spectrograph. Candidates were drawn from the Sloan Digital Sky Survey (SDSS) DR1 catalog using quasar flags set by the SDSS multi-color quasar target selection algorithm. In this paper we present our discovery spectra from 1.39 square degrees (69.5% of the COSMOS field) and a discussion of the selection method and yields. We confirmed 95 quasars, including at least 2 BALs; 80 of these are new quasars that do not appear in previous quasar confirmation follow-up studies. The candidates additionally included 184 compact emission-line galaxies, a third of which are likely Type 2 AGN, and 12 stars. The quasars span a range in magnitude of 18.3

description: In meteor physics the luminous efficiency $τ$ is used to convert the meteor's magnitude to the corresponding meteoroid's mass. However, lack of sufficiently accurate verification methods or adequate laboratory tests leave this parameter to be controversially discussed. In this work meteor/fireball data obtained by the Fireball Recovery and InterPlanetary Observation Network (FRIPON) was used to calculate the masses of the pre-atmospheric meteoroids which could in turn be compared to the meteor brightnesses to assess their luminous efficiencies. For that, deceleration-based formulas for the mass computation were used. We have found $τ$-values, as well as the shape change coefficients, of 294 fireballs with determined masses in the range of $10^{-6}$ kg - $100$ kg. The derived $τ$-values have a median of $τ_{median}$ = 2.17 %. Most of them are on the order of 0.1 % - 10 %. We present how our values were obtained, compare them with data reported in the literature, and discuss several methods. A dependence of $τ$ on the pre-atmospheric velocity of the meteor, $v_e$, is noticeable with a relation of $τ=0.0023 \cdot v_e^{2.3}$. The higher luminous efficiency of fast meteors could be explained by the higher energy released. Fast meteoroids produce additional emission lines that radiate more efficiently in specific wavelengths due to the appearance of the so-called second component of higher temperature. Furthermore, a dependence of $τ$ on the initial meteoroid mass, $M_e$, was found, with negative linear behaviour in log-log space: $τ=0.48 \cdot M_e^{-0.47}$. This implies that the radiation of smaller meteoroids is more efficient.

That is, we find quantum regular LDPC codes with various weight distributions. Furthermore our proposed codes have lots of variations for length, code rate. These codes are obtained by a descrete mathematical characterization for model matrices of quasi-cyclic LDPC codes. Our proposed codes achieve a bounded distance decoding (BDD) bound, or known as VG bound, and achieve a lower bound of the code length.

Human Reference Atlas

description: Spatially registering tissue data is critical for constructing a three dimensional human reference atlas (HRA). The Indiana University team has implemented the Registration User Interface (RUI) in order to capture the size, location, and rotation of tissue blocks in three dimensions, along with other metadata. 
This standard operating procedure (SOP) outlines the procedures for identifying spatial locations, connecting these locations with their associated metadata (e.g., de-identified donor information and publication information), and managing the HRA Registrations GitHub repository which stores original and enriched RUI data files. Metadata and spatial data are connected using the HRA RUI Locations Processor, a tool created by the Mapping Component at Indiana University (MC-IU) of the HuBMAP consortium. This SOP is intended primarily for internal use by those who create, enrich, and manage RUI data. Note that this procedure differs from using the RUI within a data portal, such as the HuBMAP Ingest Portal.

In particular, the anisotropic sample in the microwave field is subject to a torque, unless the field is directed along with one of the crystal principle axes.

description: We present a new way to construct de Sitter vacua in type IIB flux compactifications, in which the interplay of the leading perturbative and non-perturbative effects stabilize all moduli in dS vacua at parametrically large volume. Here, the closed string fluxes fix the dilaton and the complex structure moduli while the universal leading perturbative quantum correction to the Kahler potential together with non-perturbative effects stabilize the volume Kahler modulus in a dS_4-vacuum. Since the quantum correction is known exactly and can be kept parametrically small, this construction leads to calculable and explicitly realized de Sitter vacua of string theory with spontaneously broken supersymmetry.

Dietary protein quality and quantity for Atlantic salmon (Salmo salar) reared in sea water
Creators: name: Anderson, James Stewart
Publisher: name: University of British Columbia
Year: 2009

description: Two separate studies were conducted with Atlantic salmon (Salmo salar) reared in seawater. The first study investigated various in vitro and in vivo methods for the measurement of the quality of the protein in fish meals. The second study was designed to estimate the optimal dietary ratio of digestible protein (DP) to digestible energy (DE) for Atlantic salmon (0.5 -1.2 kg body weight). A second objective of the latter study was to investigate the effect of feeding diets varying in levels of digestible protein and lipid on the proximate composition, pigment deposition, and the total fatty acid profiles of whole-fillets of Atlantic salmon. Chemical (chemical composition, biogenic amines, total volatile basic-nitrogen, anisidine value, peroxide value, thiobarbituric acid value, and iodine value), in vitro (dilute-pepsin and multi-enzyme digestibilities) and in vivo assays using rats and fish as test animals were conducted on various fish meals. The results indicated that dilutepepsin digestibility was a suitable in vitro assay to evaluate the protein quality of herring meals for Atlantic salmon. However, this assay correlated poorly with the results from in vivo assays when other types offish meals (menhaden, mackerel, silver hake, groundfish) were included. Apparent metabolizable crude protein values determined using rats as the test animal, was the only in vivo assay that was found to correlate with digestibility values determined using salmon when the entire range of fish meals was assessed. Based on growth and protein and energy utilization data, the estimated optimal dietary ratio of DP to DE to rear Atlantic salmon over a size range of 0.5 kg to 1.2 kg in seawater was 17.4 g DP-MJ DE. This ratio was supplied by a diet containing 360 g DP (404 g crude protein) and 20.7 MJ DE (24.0 MJ gross energy) -kg"1 dry matter. It would also appear from this study that Atlantic salmon reared in seawater are able to tolerate up to 220 g starch-kg"1 dry matter without any detrimental effects on growth, although liver glycogen and hepatosomatic indexes were increased. Work is still needed to determine the optimal ratio of non-protein energy sources to reduce the utilization of protein for energy in salmon diets. Deposition of canthaxanthin in the fillets of Atlantic salmon was not influenced by changes in the ratio of dietary protein and lipid. The total lipid content in whole-fillets (red and white muscle with the skin removed) from Atlantic salmon was directly and significantly influenced by the dietary lipid level. The fatty acid profile of the fillets was not only affected by the dietary lipid level and the ratio of digestible protein to lipid, but also by the residual lipid content of the fish meal portion of the diet. Although the total n-3 fatty acid content of the fillets was not significantly changed by alterations of the dietary protein or lipid levels, the percentage of 20:5 n-3 did increase in direct relation to the dietary lipid level.

description: We revisit the densest binary sphere packings (DBSP) under the periodic boundary conditions and present an updated phase diagram, including newly found 12 putative densest structures over the $x - α$ plane, where $x$ is the relative concentration and $α$ is the radius ratio of the small and large spheres. To efficiently explore the DBSP, we develop an unbiased random search approach based on both the piling up method to generate initial structures in an unbiased way and the iterative balance method to optimize the volume of a unit cell while keeping the overlap of hard spheres minimized. With those two methods, we have discovered 12 putative DBSP and thereby the phase diagram is updated, while our results are consistent with those of the previous study [Hopkins et al., Phys. Rev. E 85, 021130 (2012)] with a small correction for the case of 12 or fewer spheres in the unit cell. The 5 of the new 12 densest packings are discovered in the small radius range of $0.42 \le α\le 0.50$ where several structures are competitive to each other with respect to packing fraction. Through the exhaustive search, diverse dense packings are discovered and accordingly we find that packing structures achieve high packing fractions by introducing distortion and/or combining a few local dense structural units. Furthermore, we investigate the correspondence of the DBSP with crystals based on the space group. The result shows that many structural units in real crystals, e.g., $\mathrm{LaH_{10}}$ and $\mathrm{SrGe_{2-δ}}$ being high-pressure phases, can be understood as DBSP. The correspondence implies that the densest sphere packings can be used effectively as structural prototypes for searching complex crystal structures, especially for high-pressure phases.

description: We report on the search of astrophysical gamma rays with energies in the 100 TeV to several PeV range arriving in directional and temporal coincidence with public alerts from HAWC (TeV gamma rays) and IceCube (neutrinos above ~100 TeV). The observations have been performed with the Carpet-2 air-shower detector at the Baksan Neutrino Observatory, working in the "photon-friendly" mode since 2018. Photon candidate showers are selected by their low muon content. No significant excess of the photon candidates have been observed, and upper limits on gamma-ray fluences associated with the alerts are obtained. For events with good viewing conditions, the Carpet-2 effective area for photons is of the order of the IceCube effective area for neutrinos of the same energy, so the constraints start to probe the production of neutrinos in fast flares of Galactic sources.

Transient Formation of Loops in the Core of an Active Region

description: We study the formation of transient loops in the core of the AR 11890. For this purpose, we have used the observations recorded by the Atmospheric Imaging Assembly (AIA) and the Interface Region Imaging Spectrograph (IRIS). For photospheric field configuration, we have used the line-of-sight (LOS) magnetograms obtained from the Helioseismic and Magnetic Imager (HMI). The transient is simultaneously observed in all the UV and EUV channels of AIA and the three slit-jaw images from IRIS. The co-existence of the transient in all AIA and IRIS SJI channels suggests the transient's multi-thermal nature. The transient consists of short loops located at the base of the transient as well as longe loops. A differential emission measure (DEM) analysis shows that the transient has a clumpy structure. The highest emission observed at the base is within the temperature bin of $\log\, T = 6.65 - 6.95$. We observe the longer loops at a similar temperature, albeit very feeble. Using LOS magnetograms, we conclude that the magnetic reconnection may have caused the transient. Our observations further suggest that the physics of the formation of such transients may be similar to those of typical coronal jets, albeit in different topological configurations. Such multi-wavelength observations shed light on the formation of hot plasma in the solar corona and provide further essential constraints on modeling the thermodynamics of such transients.

On the probability distribution of the stochastic saturation scale in QCD

description: It was recently noticed that high-energy scattering processes in QCD have a stochastic nature. An event-by-event scattering amplitude is characterised by a saturation scale which is a random variable. The statistical ensemble of saturation scales formed with all the events is distributed according to a probability law whose cumulants have been recently computed. In this work, we obtain the probability distribution from the cumulants. We prove that it can be considered as Gaussian over a large domain that we specify and our results are confirmed by numerical simulations.

Atmospheric dynamics of red supergiant stars and Interferometry

description: We developed a 3D pure LTE radiative transfer code to derive observables expected for RSGs, with emphasis on small scale structures, from radiative-hydrodynamic (RHD) simulations of red supergiant stars (RSGs) carried out with CO5BOLD (Freytag et al. 2002). We show that the convection-related surface structures are observable with today's interferometers. Moreover, the RHD simulations are a great improvement over parametric models for the interpretation of interferometric observations.

description: Heart failure (HF) affects at least 26 million people worldwide, so predicting adverse events in HF patients represents a major target of clinical data science. However, achieving large sample sizes sometimes represents a challenge due to difficulties in patient recruiting and long follow-up times, increasing the problem of missing data. To overcome the issue of a narrow dataset cardinality (in a clinical dataset, the cardinality is the number of patients in that dataset), population-enhancing algorithms are therefore crucial. The aim of this study was to design a random shuffle method to enhance the cardinality of an HF dataset while it is statistically legitimate, without the need of specific hypotheses and regression models. The cardinality enhancement was validated against an established random repeated-measures method with regard to the correctness in predicting clinical conditions and endpoints. In particular, machine learning and regression models were employed to highlight the benefits of the enhanced datasets. The proposed random shuffle method was able to enhance the HF dataset cardinality (711 patients before dataset preprocessing) circa 10 times and circa 21 times when followed by a random repeated-measures approach. We believe that the random shuffle method could be used in the cardiovascular field and in other data science problems when missing data and the narrow dataset cardinality represent an issue.
Designing sequential transcription logic: a simple genetic circuit for conditional memory

description: The ability to learn and respond to recurrent events depends on the capacity to remember transient biological signals received in the past. Moreover, it may be desirable to remember or ignore these transient signals conditioned upon other signals that are active at specific points in time or in unique environments. Here, we propose a simple genetic circuit in bacteria that is capable of conditionally memorizing a signal in the form of a transcription factor concentration. The circuit behaves similarly to a "data latch" in an electronic circuit, i.e. it reads and stores an input signal only when conditioned to do so by a "read command". Our circuit is of the same size as the well-known genetic toggle switch (an unconditional latch) which consists of two mutually repressing genes, but is complemented with a "regulatory front end" involving protein heterodimerization as a simple way to implement conditional control. Deterministic and stochastic analysis of the circuit dynamics indicate that an experimental implementation is feasible based on well-characterized genes and proteins. It is not known, to which extent molecular networks are able to conditionally store information in natural contexts for bacteria. However, our results suggest that such sequential logic elements may be readily implemented by cells through the combination of existing protein-protein interactions and simple transcriptional regulation.

Abacus-histories and the combinatorics of creation operators

description: Creation operators act on symmetric functions to build Schur functions, Hall--Littlewood polynomials, and related symmetric functions one row at a time. Haglund, Morse, Zabrocki, and others have studied more general symmetric functions $H_α$, $C_α$, and $B_α$ obtained by applying any sequence of creation operators to $1$. We develop new combinatorial models for the Schur expansions of these and related symmetric functions using objects called abacus-histories. These formulas arise by chaining together smaller abacus-histories that encode the effect of an individual creation operator on a given Schur function. We give a similar treatment for operators such as multiplication by $h_m$, $h_m^{\perp}$, $ω$, etc., which serve as building blocks to construct the creation operators. We use involutions on abacus-histories to give bijective proofs of properties of the Bernstein creation operator and Hall-Littlewood polynomials indexed by three-row partitions.

description: The last decade has seen major changes in the travel distribution landscape. First, the Internet began a revolution and dramatically changed the way the tourism industry works. The spreading of smartphones and social media has created further both chaos and new opportunities. While opening up new opportunities for growth, these developments also created new operational challenges. Hoteliers and other business leaders operating in the travel industry have needed to follow the latest digital trends. Failure to do so can result in competitors gaining a competitive advantage.
