description: The theme of the graduate qualification work: "Development of a vision system for a chess robot with a manipulator". The purpose of the work is to develop a vision system for a chess robot with a manipulator for the possibility of realizing an autonomous game of chess. The vision system should display the actual state of the chessboard, which means to determine the actual location of the pieces on the chessboard, as well as to be able to determine the movements of the pieces. In the course of this work, a vision system is developed to assess the state of the chessboard based on standard vision methods, as well as a neural network that determines the type of pieces on the first and eighth lines. The moves of the pieces are recorded in a file in chess notation to transfer the data to the game engine, which decides on the next move of the robot.

description: Preparing samples for analyses is perhaps the most important part to analyses. The varied functional groups present on the surface of biopolymers bestow them appropriate adsorption properties. Properties like biocompatibility, biodegradability, presence of different surface functional group, high porosity, considerable absorption capacity for water, the potential for modification, etc. turn biopolymers to promising candidates for varied applications. In addition, one of the most important parts of determination of an analyte in a matrix is sample preparation step and the efficiency of this step in solid phase extraction methods is largely dependent on the type of adsorbent used. Due to the unique properties of biopolymers they are considered an appropriate choice for using as sorbent in sample preparation methods that use from a solid adsorbent. Many review articles have been published on the application of diverse adsorbents in sample preparation methods, however despite the numerous advantages of biopolymers mentioned; review articles in this field are very few. Thus, in this paper we review the reports in different areas of sample preparation that use polysaccharides-based biopolymers as sorbents for extraction and determination of diverse organic and inorganic analytes.

description: We study the resummation of the $0$-jettiness resolution variable $\mathcal{T}_0$ for the top-quark pair production process in hadronic collisions. Starting from an effective theory framework we derive a factorisation formula for this observable which allows its resummation at any logarithmic order in the $\mathcal{T}_0\to 0$ limit. We then calculate the $\mathcal{O}(\alpha_s)$ corrections to the soft function matrices and, by employing renormalisation group equation methods, we obtain the ingredients for the resummation formula up to next-to-next-to-leading logarithmic ($\mathrm{NNLL}$) accuracy. We study the impact of these corrections to the $0$-jettiness distribution by comparing predictions at different accuracy orders: $\mathrm{NLL}$, $\mathrm{NLL}^\prime$, $\mathrm{NNLL}$ and approximate $\mathrm{NNLL}^\prime$ ($\mathrm{NNLL}^\prime_{\text{a}}$). We match these results to the corresponding fixed order calculations both at leading order and next-to-leading order for the $t\bar{t}+$jet production process, obtaining the most accurate prediction of the $0$-jettiness distribution for the top-quark pair production process at $\mathrm{NNLL}^\prime_{\text{a}}+\mathrm{NLO}$ accuracy.
Cytogenetic analysis of couples with recurrent abortions
Creators: name: Charlton, William Robert David
Publisher: name: University of British Columbia
Year: 2010

description: Cytogenetic studies of recurrent abortion have established that a significantly higher frequency of translocations exist within the population of couples presenting with histories of repeated abortion than in the general population. However, few of these studies have been able to establish a direct correlation between balanced parental rearrangement and the recurrent abortion. The present study was a cytogenetic analysis of couples with recurrent abortion, and utilized (i) the newer chromosome banding techniques and (ii) cytogenetic and morphological data on one or more abortus specimen per couple. During the course of the study 50 couples and two women were studied. Chromosomes were obtained from leukocyte blood cultures and giemsa-banded. C-banding and/or fluorescent banding was employed only if the karyotype was suspected to be abnormal. One translocation was found among 102 individuals: a t(14q15q) in a woman who had aborted a specimen with growth disorganization and a karyotype 45,XY,t(14q15q). The implications of this finding are discussed. Morphological studies on the abortuses indicated that specimens with growth disorganization are more frequent among women who are recurrent aborters with no term pregnancies and, were found to recur among this sub-population. The frequency of translocations among couples with recurrent abortion is considered in terms of the effects of translocations on reproductivity. The need for cytogenetic culture data on abortuses in serial studies on recurrent abortion is discussed.

description: We use the $4-\epsilon$ expansion to search for fixed points corresponding to $2+1$ dimensional $\mathcal{N}$=1 Wess-Zumino models of $N_{\Phi}$ scalar superfields interacting through a cubic superpotential. In the $N_{\Phi}=3$ case, we classify all SUSY fixed points that are perturbatively unitary. In the $N_{\Phi}=4$ and $N_{\Phi}=5$ cases, we focus on fixed points where the scalar superfields form a single irreducible representation of the symmetry group (irreducible fixed points). For $N_{\Phi}=4$ we show that the S5 invariant super Potts model is the only irreducible fixed point where the four scalar superfields are fully interacting. For $N_{\Phi}=5$, we go through all Lie subgroups of O(5) and then use the GAP system for computational discrete algebra to study finite subgroups of O(5) up to order 800. This analysis gives us three fully interacting irreducible fixed points. Of particular interest is a subgroup of O(5) that exhibits O(3)/Z2 symmetry. It turns out this fixed point can be generalized to a new family of models, with $N_{\Phi}=\frac{\rm N(N-1)}{2}-1$ and O(N)/Z2 symmetry, that exists for arbitrary integer N$\geq3$.

The Amesbury psalter Madonna and Child
Creators: name: Nalos, Doreen
Publisher: name: University of British Columbia
Year: 2010

description: The decoration of the Amesbury Psalter, c.1250, is of immediate appeal because of its skilled execution and the richness of its decoration. It is, moreover, interesting iconographically; the Madonna and Child page, which presents Mary as the Virgo lactans, appears to be the earliest representation of this type of Madonna which is of English provenance. Although the Virgo lactans is the oldest image of Mary known to us, it has never been the popular image of the Virgin as has been, for example, the representation of the seated Hodegetria. This essay traces the history of the Virgo lactans to the cult of Isis in Egypt, explores the image of Mary expressed in theological writings through the centuries, and examines popular concepts of the Virgin portrayed in vernacular literature, and the various ways in which the Madonna and Child theme has been visually presented. While attempts to link the theological and/ or popular concepts of Mary, which obtained at a particular time and place, with specific images of the Virgin, are sometimes erroneous, there are a few examples of the Virgo lactans of late Romanesque and early Gothic Europe which suggest that they were taken over from the Byzantine world because of a new religious atmosphere. Evidence suggests that the appearance of the Madonna as the Virgo lactans in mid-thirteenth century England might have come about through the personality of Henry III whose piety seemed to be expressed frequently in the form of artistic representation. Furthermore, his interest in the Priory of Amesbury, which has been well documented, might suggest that the so-called Sarum Master, who created the Amesbury Psalter, was one of the many artists employed by Henry, whose royal patronage of art has not been equalled in the annals of English history.

Supersolid phases of hardcore bosons on the square lattice: Correlated hopping, next-nearest neighbor hopping and frustration

description: We discuss the appearance of supersolid phases for interacting hardcore bosons on the square lattice when, in addition to the standard nearest neighbor hopping and repulsion, correlated or next-nearest neighbor hopping is present. Having in mind dimer-based quantum magnets in a field described by effective bosonic models of this kind, we put special emphasis on a comparison between the different cases of relative signs of the kinetic processes, which correspond to unfrustrated or frustrated magnetic models. In the unfrustrated case, we compare Quantum Monte Carlo simulations with a mean-field (classical) approach, which is shown to give qualitatively correct results. Using this classical approach for the frustrated case, we find that the phase diagram is generically richer than in the unfrustrated case. We also investigate in detail the differences between standard next-nearest neighbour and correlated hopping over the diagonal, with the conclusion that both cases are similar if checkerboard order is present at half-filling, while a supersolid phase can be stabilized without any adjacent solid phase only in the case of correlated hopping.

title: Purification and characterisation of gliadin fractions from wheat flour.
Creators: name: Yeboah, Nana Asare
Publisher: name: University of Kent
Year: 1991

description: Three gliadin fractions designated yni-gliadin, yv-gliadin and o-gliadin were purified to homogeneity from milled flour (variety Chinese Spring) in good yield. The proteins were characterised in terms of amino acid compositions and N-terminal amino acid sequences; these confirmed that they were typical gliadins. Mr values by SDS-PAGE and by gel filtration in GuHCl, were 4IK for the yin-gliadin by both methods, 47K and 44K respectively for the yv-gliadin and 76K and 90K for the a>-gliadin. The chemical characterisation was extended using the physical techniques of fluorescence and circular dichroism spectroscopy to derive information on the proteins’ conformational properties, and using time-resolved fluorescence to probe dynamic properties. Studies in the presence of various concentrations of urea were carried out in order to monitor unfolding of the native conformation, and the proteins’ stabilities to unfolding. The wavelength of maximum fluorescence emission (approximately 350nm) indicated that the tryptophan residues of the proteins were exposed to solvent in the native state; this was confirmed by the high values obtained for the Stern-Volmer quenching constants (12-18 M'1), indicating considerable accessibility to exogenous quencher. Time-resolved fluorescence studies indicated rotational correlation times for the tryptophan side-chains of 3-6ns indicative of free mobility of these side-chains. The far-uv CD spectra of the proteins indicated some regular secondary structure; the spectra were suggestive of some a-helices in the y-gliadins and some 6-turns in the o-gliadin. Exposure of the proteins to high concentrations of urea led to some loss of far-uv CD spectral features indicating secondary structure, implying that the proteins became 4 unfolded to some extent. However, these conditions produced only small changes in fluorescence intensity and wavelength of maximum emission and led to minimal changes in the near-uv CD spectra. These results indicate that there is little change in the environments of aromatic residues on unfolding, consistent with the interpretation that these residues are exposed in the native state. Preliminary conformational and denaturation analyses were also carried out using two peptides derived from a related y-gliadin fraction corresponding to its repetitive prolinerich N-terminal and non-repetitive S-rich C-terminal domains respectively. The properties of these peptides indicated that the properties of the intact y-gliadins could be regarded as the sums of those of the isolated domain

description: As part of our systematic study on Korean toxic mushrooms, bioactivity-guided fractionation of the MeOH extract of Amanita spissacea (Amanitaceae) fruiting bodies and chemical investigation of its cytotoxic fractions led to the isolation of (9E)-8-oxo-9-octadecenoic acid (1), (10E)-9-oxo-10-octadecenoic acid (2), (9E)-8-oxo-9-octadecenoate methyl ester (3), (9Z)-9-octadecenoate-(2'S)-2',3'-dihydroxypropyl ester (4), (9Z)-9-octadecenoic acid (5), and palmitic acid (6). The structures of the isolates were elucidated by NMR spectroscopic analysis and LC/MS analysis. Among the isolated compounds, compounds 1 and 2 exhibited the most potent cytotoxic activity in all human lung cancer cell lines examined, with IC50 values ranging from 255.7 to 321.0 μM and 250.2 to 322.5 μM, respectively. The cytotoxicity of these compounds was also found to be mediated by apoptosis associated with caspase-3 activation. These findings provide experimental evidence suggesting the potential of A. spissacea as a promising natural source for the discovery of novel anticancer drug candidates.

description: Arbitrary exponentially large unitaries cannot be implemented efficiently by quantum circuits. However, we show that quantum circuits can efficiently implement any unitary provided it has at most polynomially many nonzero entries in any row or column, and these entries are efficiently computable. One can formulate a model of computation based on the composition of sparse unitaries which includes the quantum Turing machine model, the quantum circuit model, anyonic models, permutational quantum computation, and discrete time quantum walks as special cases. Thus we obtain a simple unified proof that these models are all contained in BQP. Furthermore our general method for implementing sparse unitaries simplifies several existing quantum algorithms.

description: We construct control policies that ensure bounded variance of a noisy marginally stable linear system in closed-loop. It is assumed that the noise sequence is a mutually independent sequence of random vectors, enters the dynamics affinely, and has bounded fourth moment. The magnitude of the control is required to be of the order of the first moment of the noise, and the policies we obtain are simple and computable.

description: We build spherically symmetric wormholes within the DGP theory. We calculate the energy localized on the shell, and we find that for certain values of the parameters wormholes could be supported by matter not violating the energy conditions. We also show that it could exist solitonic shells charaterized by zero pressure and zero energy; thereafter we make some observations regarding their dynamic on the phase plane.

description: The complexities involved in modeling the transmission dynamics of COVID-19 has been a major roadblock in achieving predictability in the spread and containment of the disease. In addition to understanding the modes of transmission, the effectiveness of the mitigation methods also needs to be built into any effective model for making such predictions. We show that such complexities can be circumvented by appealing to scaling principles which lead to the emergence of universality in the transmission dynamics of the disease. The ensuing data collapse renders the transmission dynamics largely independent of geopolitical variations, the effectiveness of various mitigation strategies, population demographics, etc. We propose a simple two-parameter model -- the Blue Sky model -- and show that one class of transmission dynamics can be explained by a solution that lives at the edge of a blue sky bifurcation. In addition, the data collapse leads to an enhanced degree of predictability in the disease spread for several geographical scales which can also be realized in a model-independent manner as we show using a deep neural network. The methodology adopted in this work can potentially be applied to the transmission of other infectious diseases and new universality classes may be found. The predictability in transmission dynamics and the simplicity of our methodology can help in building policies for exit strategies and mitigation methods during a pandemic.

description: Using LDA+GTB (local density approximation+generalized tight-binding) hybrid scheme we investigate the band structure of the electron-doped high-$T_c$ material Sm$_{2-x}$Ce$_{x}$CuO$_4$. Parameters of the minimal tight-binding model for this system (the so-called 3-band Emery model) were obtained within the NMTO ($N$-th order Muffin-Tin orbital) method. Doping evolution of the dispersion and Fermi surface in the presence of electronic correlations was investigated in two regimes of magnetic order: short-range (spin-liquid) and long-range (antiferromagnetic metal). Each regime is characterized by the specific topologies of the Fermi surfaces and we discuss their relation to recent experimental data.

Material-form relationships on talus slopes in southwestern British Columbia
Creators: name: Evans, Stephen G.
Publisher: name: University of British Columbia
Year: 2010

description: Talus slopes were investigated in a process-material-response framework. The work was concerned with clarifying concepts and terminology concerning slopes of granular materials and interpreting talus slope angles in the light of this clarification; verifying this interpretation in a field investigation; and seeking statistical relationships between talus slope angle and material properties. Field investigations were carried out in South West British Columbia. Slopes were investigated in the southern Coast Mountains and. in the Similkameen Valley. Theoretical concepts relating to slopes in granular material were discussed. Two angles of repose were distinguished; a peak angle of accumulation (α[sub c]) defined as the steepest angle attainable by a mass of granular material, and a lower angle, the angle of repose (α[sub r]) to which the material slides after failure. α[sub c] and α[sub r] were related to concepts of shear resistance and the angle of internal friction (0); α[sub c] was linked to 0 and α[sub r] was thought to correspond to the residual angle of internal friction for a given material. α[sub c] and α[sub r] were related through a regression equation of the form; α[sub c] = -3.29 + 1.273 (α[sub r]) These concepts were examined with reference to talus slope form and some of the contradictions in the literature were presented. The characteristic and limiting slope angles noted in review were found to correspond to α[sub r] and α[sub c] respectively for talus material. This correspondence gave rise to the supply induced transformation hypothesis which appeared to provide a suitable transformation model for rock-fall talus. The relationship between material properties and slope angle was examined using parametric multivariate statistics. Significant correlations, at the 99% level, were obtained between segment angle and size (inverse) and segment angle and sorting (direct). At the 95% level significant correlations were found between segment angle and sphericity (inverse) and Zingg's Flatness Ratio (direct). In multiple regression analysis only 37.11% of the variation in slope angle was accounted for by material properties (sorting and the variance in Zingg's Elongation Ratio) at the 95% level of significance. Shape factors contribute very little to the explained variance whilst fabric related variables contribute nothing. Implications of these results for talus slope development were discussed. Rockfall talus slopes subject to supply-induced transformation processes are thought to have a distinctive morphology which may be an explanation for the typical profile concavity noted on such slopes. Determinants on the frequency of talus slides were examined. The problem of the basal layer cannot be ignored in a consideration of talus slope development models.

description: The concept and prototype implementation of a satellite on-board SAR processing chain designed for Maritime Situation Awareness is described. It aims to reduce the latency between data acquisition and product delivery to about 3-4 minutes. SAR processing is one component of a larger prototype system being developed in the frame of the H2020 EO-ALERT project. It further comprises an optical data chain, data compression/encryption, and delivery. The system employs multiple boards with Multi-Processor-System-On-Chip (MPSoC) combining FPGAs and ARM CPUs. Low latency data processing was a key development goal, hence, a tailored workflow and adapted L1 and L2 processing algorithms ensure that the requirements for latency and product quality are met. The SAR processor is designed to generate SAR imagery from TerraSAR-X stripmap data for subsequent ship detection and sea state determination. The achieved overall L1 and L2 processing times were 60 s for ship detection and 105 s for sea state determination on a 1125 km² SAR image. These results enable further work towards a new generation of Earth Observation satellites with similar processing capabilities on-board, providing users with products only a few minutes after acquisition. © 2021 EO-ALERT All Rights Reserved

description: It is proved that, if $k\ge2$ is a fixed integer and $1 \ll H \le X/2$, then $$ \int_{X-H}^{X+H}Δ^4_k(x)\d x \ll_εX^ε\Bigl(HX^{(2k-2)/k} + H^{(2k-3)/(2k+1)}X^{(8k-8)/(2k+1)}\Bigr), $$ where $Δ_k(x)$ is the error term in the general Dirichlet divisor problem. The proof uses the Vorono{\"ı}--type formula for $Δ_k(x)$, and the bound of Robert--Sargos for the number of integers when the difference of four $k$--th roots is small. We also investigate the size of the error term in the asymptotic formula for the $m$-th moment of $Δ_2(x)$.

description: We prove the unitary equivalence of the inverse of the Krein--von Neumann extension (on the orthogonal complement of its kernel) of a densely defined, closed, strictly positive operator, $S\geq εI_{\mathcal{H}}$ for some $ε>0$ in a Hilbert space $\mathcal{H}$ to an abstract buckling problem operator. In the concrete case where $S=\bar{-Δ|_{C_0^\infty(Ω)}}$ in $L^2(Ω; d^n x)$ for $Ω\subset\mathbb{R}^n$ an open, bounded (and sufficiently regular) domain, this recovers, as a particular case of a general result due to G. Grubb, that the eigenvalue problem for the Krein Laplacian $S_K$ (i.e., the Krein--von Neumann extension of $S$), \[ S_K v = λv, \quad λ\neq 0, \] is in one-to-one correspondence with the problem of {\em the buckling of a clamped plate}, \[ (-Δ)^2u=λ(-Δ) u \text{in} Ω, \quad λ\neq 0, \quad u\in H_0^2(Ω), \] where $u$ and $v$ are related via the pair of formulas \[ u = S_F^{-1} (-Δ) v, \quad v = λ^{-1}(-Δ) u, \] with $S_F$ the Friedrichs extension of $S$. This establishes the Krein extension as a natural object in elasticity theory (in analogy to the Friedrichs extension, which found natural applications in quantum mechanics, elasticity, etc.).

description: In the multi-fractal analysis of large scale matter distribution, the scale of transition to homogeneity is defined as the scale above which the fractal dimension of underlying point distribution is equal to the ambient dimension of the space in which points are distributed. With finite sized weakly clustered distribution of tracers obtained from galaxy redshift surveys it is difficult to achieve this equality. Recently we have defined the scale of homogeneity to be the scale above which the deviation of fractal dimension from the ambient dimension becomes smaller than the statistical dispersion. In this paper we use the relation between the fractal dimensions and the correlation function to compute the dispersion for any given model in the limit of weak clustering amplitude. We compare the deviation and dispersion for the LCDM model and discuss the implication of this comparison for the expected scale of homogeneity in the concordant model of cosmology. We estimate the upper limit to the scale of homogeneity to be close to 260 Mpc/h for the LCDM model. Actual estimates of the scale of homogeneity should be smaller than this as we have considered only statistical contribution to the dispersion in fractal dimension and we have ignored cosmic variance and contributions due to survey geometry and the selection function. We find that as long as non linear correction are insignificant, scale of homogeneity as defined above does not change with epoch. The scale of homogeneity depends very weakly on the choice of tracer of the density field. Thus the suggested definition of the scale of homogeneity is fairly robust.

title: Coercive diplomacy : the Nkomati accord between Mozambique and South Africa.
Creators: name: Al-Khaledi, Murdhi Awad Nassar
Publisher: name: University of Kent
Year: 1990

description: The independence gained by Angola and by Mozambique in 1974 and by Zimbabwe in 1980 caused a 'security vacuum' for the Republic of South Africa, since it had lost its buffer zone. Accompanying these events, there was an upsurge in guerrilla activities led by the ANC, PAC and SWAPO with the support of the FLS. In response to these developments, South Africa implemented a strategy of coercion designed to deal with any threat to its internal security and maintain its external influence as a regional power. In the 1980's, therefore, the region has witnessed an escalating pattern of coercion, aggression and destabilisation by Pretoria, aimed against the independent Southern African countries. These policies have had a devastating effect on the stability of the region as a whole, as well as on the economic, political, military and the like developments of the FLS-SADCC countries. The aim of this study is to investigate the nature of this coercive diplomacy exercised by the South African government in Southern Africa. The best example of South Africa's strategy of coercion is the signing of the Nkomati Accord in 1984 with Mozambique. The reasons behind Mozambique's signing of the Accord are examined in detail and the reactions of the FLS are presented and analysed. These reactions are drawn from interviews conducted by the researcher in Southern Africa in 1988. They deal with the implication of the signing of the Accord for the solidarity of the FLS and their support of the liberation movements.

description: Torsion and curvature could play a fundamental role in explaining cosmological dynamics. f(R)-gravity with torsion is an approach aimed to encompass in a comprehensive scheme all the Dark Side of the Universe (Dark Energy and Dark Matter). We discuss the field equations in empty space and in presence of perfect fluid matter taking into account the analogy with the metric-affine formalism. The result is that the extra curvature and torsion degrees of freedom can be dealt under the standard of an effective scalar field of fully geometric origin. The initial value problem for such theories is also discussed.

description: SUPERBOX is known as a very efficient particle-mesh code with highly-resolving sub-grids. Nevertheless, the height of a typical galactic disc is small compared to the size of the whole system. Consequently, the numerical resolution in z-direction, i.e. vertically with respect to the plane of the disc, remains poor. Here, we present a new version of SUPERBOX that allows for a considerably higher resolution along z. The improved code is applied to investigate disc heating by the infall of a galaxy satellite. We describe the improvement and communicate our results. As an important application we discuss the disruption of a dwarf galaxy within a disc-bulge-halo galaxy that consists of some 10^6 particles.
