description: We address the problems of bearing-only consensus and formation control, where each agent can only measure the relative bearings of its neighbors and relative distances are not available. We provide stability results for the Filippov solutions of two gradient-descent laws from non-smooth Lyapunov functions in the context of differential inclusion. For the consensus and formation control problems with undirected sensing topologies, we prove finite-time and asymptotic convergence of the proposed non-smooth gradient flows. For the directed consensus problem, we prove asymptotic convergence using a different non-smooth Lyapunov function given that the sensing graph has a globally reachable node. Finally, For the directed formation control problem we prove asymptotic convergence for directed cycles and directed acyclic graphs and also introduce a new notion of bearing persistence which guarantees convergence to the desired bearings.

description: Differential local adaptation restricts gene flow between populations inhabiting distinct environments, resulting in isolation by adaptation. In addition to the statistical inferences of genotype-environment associations, an integrative approach is needed to investigate the effect of local adaptation on population divergence at the ecological, genetic and genomic scale. Here, we combine reciprocal transplant, genome-environment association and QTL mapping to investigate local adaptation in Boechera stricta (Drummond's rockcress). With reciprocal transplant experiment, we found local genetic groups exhibit phenotypic characteristics corresponding to the distinct selection forces from different water availability. In the genetic level, the local allele of a major fitness QTL confers higher and sturdier flowering stalks, maximizing the fecundity fitness component under sufficient water supply, and its genetic variation is associated with precipitation across the landscape. In the genomewide scale, we further showed that multiple loci associated with precipitation are highly differentiated between genetic groups, suggesting that local adaptation has a widespread effect on reducing gene flow. This study provides one of the few comprehensive examples demonstrating how local adaptation facilitates population divergence at the trait, gene, and genome level.

description: BOJNOJ Consultants has created a detailed design report which describes our suggested design for Phase 4 of the Wesbrook Mall Redesign from W 16th Avenue to Thunderbird Avenue. In recent years, the University of British Columbia campus has experienced consistent development and growth. As the population of both the campus and the Point Grey area in general continues to increase, ensuring accessibility is key to maintaining the well-being of all residents. Therefore, the main objective of the redesign is to provide a sustainable, resilient, and efficient solution to the transportation needs of the UBC community. Our team considered criteria from a wide range of perspectives and have created a design that prioritizes both mobility and environmental protection to improve the experience for all users. BOJNOJ Consultants’ proposed design will create a separate raised cyclist lane in both the northbound and southbound direction. The positioning of the parking lanes will be swapped with the current cycling lanes to eliminate conflicts between vehicles and cyclists and prevent accidents. An overpass will be added near the Panhellenic Village to comply with UBC’s desires. Additionally, several green infrastructure upgrades will be implemented throughout the corridor to improve rainwater infiltration. Additionally, the necessary maintenance has been accounted for and our team has provided the advised procedures to ensure proper function of all key corridor components. Taking into consideration geometry rearrangements, infrastructure upgrades, and overpass construction, the overall project is estimated to cost $6,047,901.61. Construction is scheduled to begin early May 2022 and be completed over 12-week period. The following report documents our detailed design solution, the decision-making process used to arrive at that design and important constraints and criteria evaluated.

title: An investigation of some relationships between learning and personality
Creators: name: Robertson, Ivan Tony
Publisher: name: The Open University
Year: 1977

description: This study attempted to examine relationships between certain indices of learning style and efficiency and some aspects of personality. The methods adopted involved detailed study of a small sample of students (N = 14), learning a large and complex body of subject matter. Four main indices of learning were studied. 1) Appreciation Span: the extent to which a learner planned ahead 2) Exploration: the extent to which a learner requested an outline of topics that he did not yet understand. 3) Errors: the extent to which a learner made mistakes when asked to explain topics that he had learned about. 4) Route taken: the extent to which a learner chose a wide range of topics to work on and extended his knowledge on a broad front, or confined his learning to a narrower 'in depth' study of one area at a time. Hypotheses concerning appreciation span, exploration and errors focused on possible interrelationships between these variables, extraversion-introversion and associated characteristics. The results indicated no relationships between the distance ahead that students planned, the amount of exploration that they engaged in and extraversion-introversion. Possible explanations and implications of the results are discussed. Hypotheses derived from previous work suggesting that extraverts have greater tolerance of ambiguity than introverts and thus make fewer errors when learning in unstructured, ambiguous situations were supported by the data. A detailed theoretical discussion of attention deployment is presented and followed by an empirical examination of the extent to which the students studied developed their understanding on a broad or narrow front. Hypotheses concerning the relationships between this learning style characteristic and attention deployment, cognitive complexity and flexibility in problem-solving were supported by the data; indicating positive relationships between a "breadth-first' learning style, wide (or diffuse) attention deployment, a high level of cognitive complexity and a flexible approach to problem-solving.

description: Resource Description Framework (RDF) can seen as a solution in today's landscape of knowledge representation research. An RDF language has symmetrical features because subjects and objects in triples can be interchangeably used. Moreover, the regularity and symmetry of the RDF language allow knowledge representation that is easily processed by machines, and because its structure is similar to natural languages, it is reasonably readable for people. RDF provides some useful features for generalized knowledge representation. Its distributed nature, due to its identifier grounding in IRIs, naturally scales to the size of the Web. However, its use is often hidden from view and is, therefore, one of the less well-known of the knowledge representation frameworks. Therefore, we summarise RDF v1.0 and v1.1 to broaden its audience within the knowledge representation community. This article reviews current approaches, tools, and applications for mapping from relational databases to RDF and from XML to RDF. We discuss RDF serializations, including formats with support for multiple graphs and we analyze RDF compression proposals. Finally, we present a summarized formal definition of RDF 1.1 that provides additional insights into the modeling of reification, blank nodes, and entailments.

Symmetry breaking and turbulence in perturbed plane Couette flow

Year: 2003
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: Perturbed plane Couette flow containing a thin spanwise-oriented ribbon undergoes a subcritical bifurcation at Re = 230 to a steady 3D state containing streamwise vortices. This bifurcation is followed by several others giving rise to a fascinating series of stable and unstable steady states of different symmetries and wavelengths. First, the backwards-bifurcating branch reverses direction and becomes stable near Re = 200. Then, the spanwise reflection symmetry is broken, leading to two asymmetric branches which are themselves destabilized at Re = 420. Above this Reynolds number, time evolution leads first to a metastable state whose spanwise wavelength is halved and then to complicated time-dependent behavior. These features are in agreement with experiments.

title: Intestinal amino acid absorption in development
Creators: name: Murphy, Sean
Publisher: name: The Open University
Year: 1978

description: 1. An in vitro preparation was employed to investigate uptake of a number of neutral and basic amino acids by the developing rat small intestine. 2. The kinetics of uptake of these substrates were determined from birth to maturity and changes described in the affinity for and rate of uptake by the jejunum particularly around the time of weaning. All the amino acids had a higher affinity for uptake and were accumulated to a greater extent by the jejunum during the first three weeks of life as compared with older animals. Similar kinetic profiles for certain amino acids suggested that they shared common uptake systems. 3. The specificity of neutral and basic amino acid uptake was examined developmentally by employing inhibition kinetics. The results suggested that while distinct neutral and basic uptake systems were present at birth, there was some functional overlap : neutral amino acids were able to use basic systems and vice versa. After three weeks of age, this picture changed and the uptake systems were much more defined. 4. Uptake of amino acids was found to depend to a large extent on energy derived from oxidative phosphorylation even at birth. This energy expenditure was directed toward maintaining a Na+ gradient across the enterocyte membrane and co-transport of neutral amino acids with Na+ thus promoted accumulation. The basic amino acids, however, were found not to be dependent on the existence of such an ion gradient but they did require the presence of Na+ ions for carrier binding, and their uptake demanded energy expenditure at some stage. 5. Precociously inducing the appearance of a functionally distinct absorptive cell was found to change the kinetics of basic amino acid uptake in the jejunum, and promote such specificity of uptake as was seen in older animals. 6. Changes in the developing small intestine itself have led to problems in the expression of results and these have been discussed at length in terms of their relation to these and other findings. 7. These results on the development of amino acid uptake systems are discussed in the context of morphological changes that occur postnatally in the small intestine, with particular reference to the appearance of a functionally distinct absorptive cell around the time of weaning, and are related to the physiological requirements of the neonatal animal.
Paxos vs Raft: Have we reached consensus on distributed consensus?

description: Distributed consensus is a fundamental primitive for constructing fault-tolerant, strongly-consistent distributed systems. Though many distributed consensus algorithms have been proposed, just two dominate production systems: Paxos, the traditional, famously subtle, algorithm; and Raft, a more recent algorithm positioned as a more understandable alternative to Paxos. In this paper, we consider the question of which algorithm, Paxos or Raft, is the better solution to distributed consensus? We analyse both to determine exactly how they differ by describing a simplified Paxos algorithm using Raft's terminology and pragmatic abstractions. We find that both Paxos and Raft take a very similar approach to distributed consensus, differing only in their approach to leader election. Most notably, Raft only allows servers with up-to-date logs to become leaders, whereas Paxos allows any server to be leader provided it then updates its log to ensure it is up-to-date. Raft's approach is surprisingly efficient given its simplicity as, unlike Paxos, it does not require log entries to be exchanged during leader election. We surmise that much of the understandability of Raft comes from the paper's clear presentation rather than being fundamental to the underlying algorithm being presented.

Year: 2020

description: When measuring the roughness of rough surfaces, the limited sizes of scanned areas lead to its systematic underestimation. Levelling by polynomials and other filtering used in real-world processing of atomic force microscopy data increases this bias considerably. Here a framework is developed providing explicit expressions for the bias of squared mean square roughness in the case of levelling by fitting a model background function using linear least squares. The framework is then applied to polynomial levelling, for both one-dimensional and two-dimensional data processing, and basic models of surface autocorrelation function, Gaussian and exponential. Several other common scenarios are covered as well, including median levelling, intermediate Gaussian--exponential autocorrelation model and frequency space filtering. Application of the results to other quantities, such as Rq, Sq, Ra and~Sa is discussed. The results are summarized in overview plots covering a range of autocorrelation functions and polynomial degrees, which allow graphical estimation of the bias.

title: An interpretation of Landsat imagery of southeast Botswana and a review of the practical uses, merits and disadvantages of the imagery.
Creators: name: Hutton, Susan Mary
Publisher: name: The Open University
Year: 1978

description: This work aims to show how Landsat imagery may be used to compile a regional study in a developing country at relatively little cost since the following geological, geomorphological and land use interpretations of southeast Botswana are based on photographic Landsat data. The study area lies on the northern margin of the Kaapvaal Craton, just south of the east-northeast Limpopo Mobile Belt. Two major east-northeast lineaments and considerably more linear structures than are shown on the published geological maps were identified from the imagery. Movement along the principal, structural lines of weakness seems to have continued throughout late Archaean and early Proterozoic times. The Transvaal, Kanye and Dipotsana Basins are readily distinguished from the neighbouring Gaborone Granite which seems to comprise two "plutons" orientated parallel to the two major, structural directions of the Kaapvaal Craton - northwest and east-northeast. These "plutons" lie between major sets of fractures. The geomorphology of the area is closely related to the geological structure. Since there is little economic mineralisation, it was not possible to expound a definitive relationship between Landsat identified lineaments and ore deposits. A landsat image mosaic illustrates the different tectonic elements within Botswana. Comparisons of the different MSS wavelength bands showed that a late Spring, false-colour image acquired when the atmosphere is clear of haze is that most preferable for interpretation, followed by black and white MSS 5, then 7, transparencies, at the same season. Simple enhancement techniques proved disappointing on trial but the use of colour infra-red film on aerial reconnaissance yielded comparative results with false-colour Landsat imagery.

Specifically, the transformations considered apply to hypergeometric solutions of hypergeometric differential equations with the local exponent differences $1/K,1/L,1/M$ such that $K,L,M$ are positive integers and $1/K+1/L+1/M<1$. All algebraic transformations of these Gauss hypergeometric functions are considered. We show that apart from classical transformations of degree 2, 3, 4, 6 there are several other transformations of degree 6, 8, 9, 10, 12, 18, 24. Besides, we present an algorithm to compute relevant Belyi functions explicitly.

title: Image intensifier studies of low intensity triboluminescence, electroluminescence and photoluminescence of solids
Creators: name: Chapman, Geoffrey N
Publisher: name: The Open University
Year: 1981

description: A four-stage magnetically focused image intensifier tube (IIT) with an optical power gain of about 106 was used in both spatial and spectral investigations of solids. The spectral studies involved the design and construction of a spectrograph to disperse light across the input photocathode of the IIT. Spectra were then amplified by the IIT and displayed on the output phospher where they were photographically recorded. The system was intensity corrected and used to measure the triboluminescence (TL) spectra from small quantities (- 10 grams) of material. The TL spectra of minerals including amethyst, zircon, and various calcites and fluorites were recorded for the first time with high spectral resolution. Origins of these TL spectra were investigated, and many were correlated with appropriate term diagrams. The results are discussed following a detailed and critical review of the literature. Light emission from cutting a number of glasses and polymers on a diamond saw was also recorded and the (continuum like) spectra obtained were compared with black body radiation (at the temperature estimated to occur at a crack tip due to release of plastic deformation energy). Differences were noted in some cases between the TL which occurred at fracture and the light emission of the same samples when cut on the diamond saw. These differences are discussed with reference to the photoluminescence spectra of the samples. Thermoluminescence spectra were also recorded, again using an IIT spectrograph, and the results were compared with TL of similar specimens. A spatial study of semiconductors was made by projecting the image of a small area (typically 50 um2) of the specimen, using a microscope, onto the input photocathode of the IIT. The high optical power gain of the system was utilized in a 'spatial investigation of semiconductor electroluminescence (EL) and photoluminescence (PL). The EL of GaP and Ga1-xAlxAs (x = 0.35 and 0.52) was recorded and the EL of the latter was compared with cathodoluminescence of the same specimen to highlight the complementary nature of the techniques. The homogeneity of the PL of a sample of amorphous silicon was studied at 77K in a specially constructed cryostat. The application of the method to other homogeneity measurements is discussed.

description: Imaging-based early diagnosis of Alzheimer Disease (AD) has become an effective approach, especially by using nuclear medicine imaging techniques such as Positron Emission Topography (PET). In various literature it has been found that PET images can be better modeled as signals (e.g. uptake of florbetapir) defined on a network (non-Euclidean) structure which is governed by its underlying graph patterns of pathological progression and metabolic connectivity. In order to effectively apply deep learning framework for PET image analysis to overcome its limitation on Euclidean grid, we develop a solution for 3D PET image representation and analysis under a generalized, graph-based CNN architecture (PETNet), which analyzes PET signals defined on a group-wise inferred graph structure. Computations in PETNet are defined in non-Euclidean, graph (network) domain, as it performs feature extraction by convolution operations on spectral-filtered signals on the graph and pooling operations based on hierarchical graph clustering. Effectiveness of the PETNet is evaluated on the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset, which shows improved performance over both deep learning and other machine learning-based methods.

description: The hydromagnetic structure of a neutron star accreting symmetrically at both magnetic poles is calculated as a function of accreted mass, M_a, and polar cap radius,starting from a centered magnetic dipole and evolving through a quasistatic sequence of two-dimensional, Grad-Shafranov equilibria. The calculation is the first to track fully the growth of high-order magnetic multipoles, due to equatorward hydromagnetic spreading, while simultaneously preserving flux freezing and a self-consistent mass-flux distribution. Equilibria are constructed numerically by an iterative scheme and analytically by Green functions. Two key results are obtained, with implications for recycled pulsars. (i) The mass required to significantly reduce the magnetic dipole moment, 10^{-5} Msun, greatly exceeds previous estimates (~ 10^{-10} Msun), which ignored the confining stress exerted by the compressed equatorial magnetic field. (ii) Magnetic bubbles, disconnected from the stellar surface, form in the later stages of accretion (M_a > 10^{-4} Msun).

description: Systems of randomly packed, macroscopic elements, from jammed spherical grains to tangled long filaments, represent a broad class of disordered meta-materials with a wide range of applications and manifestations in nature. A `bird nest' presents itself at an interface between hard round grains described by granular physics to long soft filaments, the center of textile material science. All of these randomly packed systems exhibit forms of self assembly, evident through their robust packing statistics, and a common, unusual elastoplastic response to oedometric compression. In reviewing packing statistics, mechanical response characterization and consideration of boundary effects, we present a perspective that attempts to establish a link between the bulk and local behaviour of a pile of sand and a wad of cotton, demonstrating the nest's relationship with each. Finally, potential directions for impactful applications are outlined.

description: Observations show that solar activity is distributed non-axisymmetrically, concentrating at "preferred longitudes". This indicates the important role of non-axisymmetric magnetic fields in the origin of solar activity. We investigate the generation of the non-axisymmetric fields and their coupling with axisymmetric solar magnetic field. Our kinematic generation (dynamo) model operating in a sphere includes solar differential rotation, which approximates the differential rotation obtained by inversion of helioseismic data, modelled distributions of the turbulent resistivity, non-axisymmetric mean helicity, and meridional circulation in the convection zone. We find that (1) the non-axisymmetric modes are localised near the base of the convection zone, where the formation of active regions starts, and at latitudes around $30^{\circ}$; (2) the coupling of non-axisymmetric and axisymmetric modes causes the non-axisymmetric mode to follow the solar cycle; the phase relations between the modes are found. (3) The rate of rotation of the first non-axisymmetric mode is close to that determined in the interplanetary space.

description: At finite density, the spontaneous breakdown of an internal non-Abelian symmetry dictates, along with gapless modes, modes whose gap is fixed by the algebra and proportional to the chemical potential: the gapped Goldstones. Generically the gap of these states is comparable to that of other non-universal excitations or to the energy scale where the dynamics is strongly coupled. This makes it non-straightforward to derive a universal effective field theory (EFT) description realizing all the symmetries. Focusing on the illustrative example of a fully broken SU(2) group, we demonstrate that such an EFT can be constructed by carving out around the Goldstones, gapless and gapped, at small 3-momentum. The rules governing the EFT, where the gapless Goldstones are soft while the gapped ones are slow, are those of standard nonrelativistic EFTs, like for instance nonrelativistic QED. In particular, the EFT Lagrangian formally preserves gapped Goldstone number, and processes where such number is not conserved are described inclusively by allowing for imaginary parts in the Wilson coefficients. Thus, while the symmetry is manifestly realized in the EFT, unitarity is not. We comment on the application of our construction to the study of the large charge sector of conformal field theories with non-Abelian symmetries.

description: It is known that the universal cover of compact Riemann surface is either the projective line, the complex plane or the unit disk. In this article we construct a very explicit family of complex surfaces that gives rise to uncountably many mutually non-biholomorphic universal covers.

description: We demonstrate feedback cooling of a millimeter-scale, 40 kHz SiN membrane from room temperature to 5 mK (3000 phonons) using a Michelson interferometer, and discuss the challenges to ground state cooling without an optical cavity. This advance appears within reach of current membrane technology, positioning it as a compelling alternative to levitated systems for quantum sensing and fundamental weak force measurements.

Les cours boursiers de la zone UEMOA suivent-ils une marche aléatoire ?

description: Cet article teste l’hypothèse d’efficience des marchés boursiers dans le cas du marché boursier de l’Union Economique et Monétaire Ouest Africaine (UEMOA), afin de vérifier si l’évolution future des indices boursiers journaliers, de la Bourse Régionale des Valeurs Mobilières (BRVM) est imprévisible ou fonction des variations passées. A cet effet, notre méthodologie choisie se base sur l’approche de Box et Jenkins à travers l’analyse du processus ARIMA. Nos principaux résultats portant sur la période du 03/01/2005 au 19/08/2021 montrent que les cours boursiers ne se comportent pas tels des processus de marche aléatoire. Dit autrement, il est possible de prévoir l’évolution de la rentabilité des cours boursiers de l’UEMOA avec un décalage de trois jours. Cette situation peut être rattachée à la fois à l’existence de coûts de transaction élevés, à l’hétérogénéité des acteurs du marché financier et à l’incapacité des investisseurs à exploiter toutes les opportunités de gain sans compromettre la valeur fondamentale des titres. Les décideurs devraient améliorer l’accès à l’information boursière afin de faciliter la transition d’une économie d’endettement vers une économie de marché financier.

description: We are interested in analyzing the effect of bandwidth sharing for telecommunication networks. More precisely, we want to calculate which routes are bottlenecks by means of large deviations techniques. The method is illustrated in this paper on a star network, where the bandwidth is shared between customers according to the so-called min policy. We prove a sample path large deviation principle for a rescaled process n^{-1}Q_{nt}, where Q_t represents the joint number of connections at time t. The main result is to compute the rate function explicitly. The major step consists in deriving large deviation bounds for an empirical generator constructed from the join number of customers and arrivals on each route. The rest of the analysis relies on a suitable change of measure together with a localization procedure. An example shows how this can be used practically.
Topology in shallow-water waves: a violation of bulk-edge correspondence

description: We study the two-dimensional rotating shallow-water model describing Earth's oceanic layers. It is formally analogue to a Schrödinger equation where the tools from topological insulators are relevant. Once regularized at small scale by an odd-viscous term, such a model has a well-defined bulk topological index. However, in presence of a sharp boundary, the number of edge modes depends on the boundary condition, showing an explicit violation of the bulk-edge correspondence. We study a continuous family of boundary conditions with a rich phase diagram, and explain the origin of this mismatch. Our approach relies on scattering theory and Levinson's theorem. The latter does not apply at infinite momentum because of the analytic structure of the scattering amplitude there, ultimately responsible for the violation.

title: Kinetics of phase segregation in a quenched alloy
Creators: name: Buhagiar, Anton
Publisher: name: The Open University
Year: 1981

description: We model the time evolution of a lattice gas or binary alloy quenched from infinite temperature (T = ∞) to T < T c, the critical temperature. The alloy is represented on a simple cubic lattice of N sites by the Ising Model with Kawasaki dynamics assuming a nearest neighbour attraction. The basic kinetic process is the interchange of two unlike particles on adjacent sites, and is Markovian. The unit of time t is taken as one attempted interchange per lattice site. The differential equation used is that of Becker-Doring which assumes the droplets of the new phase to grow or shrink by absorbing one particle at a time. For each size of droplet the equation contains two kinetic coefficients a& and b& which are related to the probability that an &-droplet absorbs or emits one particle. The two coefficients are related by a detailed balance condition. We first find the coefficient a& in the limit of zero density a&(0), assuming steady state diffusion as in the Lifshitz Slyozov theory. We express a&(0) as the solution of a lattice diffusion problem describing the motion of the other particles near a given &-cluster with suitable boundary conditions at infinity and at the surface of the cluster. The differential equation is solved numerically for densities p = 0.05, 0.075, 0.10. The solution compares well with histograms from real alloys (Ni.- Al) and computer simulation of alloys, at the same value of &*, which characterizes the supersaturation. To determine &* (t), we need to know the variation of a& with &*. We find a& is negative for small &* (or high supersaturation) indicating the presence of spinodal decomposition initially. For &* > 26, however, a& is approximately constant (2.0) for 0 < t < 7000. Also &* is linear over most of this range and is well predicted by the differential equation over 0 < t < 5000. For larger densities and for 7000 > t > 5000, however, the differential equation underestimates &* because of coalescence.
