Polarization transfer in deuterium at intermediate energies
Creators: name: Felawka, Larry Thomas
Publisher: name: University of British Columbia
Year: 2010

description: A set of experiments to determine the optimum polarization transfer parameter for the production of polarized neutron beams using the reaction D(p,n) 2p and to determine the optimum neutron production angle are described. Measurements of the variation of neutron polarization with energy at a neutron production angle of 9° in the lab. and of the analyzing power for neutrons of a polarimeter containing a 6 cm. thick carbon target are also described. The polarization transfer parameter R[sub t] was found to be about 5 times as large as the parameter D[sub t] for neutrons emerging at 9° in the lab. at 210 and 343 MeV incident proton energies, and of the same order as D[sub t] at 516 MeV. The neutron polarization peaked at about 10° at 210 and 343 MeV and was relatively insensitive to angle at 516 MeV. For neutrons emerging at 9°, R[sub t] was observed to decrease from -.94±.12 at 237 MeV to -.49±.07 at 516 MeV.

description: Monte Carlo computer simulations in the canonical and grand canonical statistical ensemble were used to explore the properties of the central force (CF1) water model. The intramolecular structure of the H$_2$O molecule is well reproduced by the model. Emphasis was made on hydrogen bonding, and on the tehrahedral, $q$, and translational, $τ$, order parameters. An energetic definition of the hydrogen bond gives more consistent results for the average number of hydrogen bonds compared to the one-parameter distance criterion. At 300 K, an average value of 3.8 was obtained. The $q$ and $τ$ metrics were used to elucidate the water-like anomalous behaviour of the CF1 model. The structural anomalies lead to the density anomaly, with a good agreement of the model's density with the experimental $ρ(T)$ trends. The chemical potential-density projection of the model's equation of state was explored. Vapour-liquid coexistence was observed at sufficiently low temperatures.

description: Transformer-based rankers have shown state-of-the-art performance. However, their self-attention operation is mostly unable to process long sequences. One of the common approaches to train these rankers is to heuristically select some segments of each document, such as the first segment, as training data. However, these segments may not contain the query-related parts of documents. To address this problem, we propose query-driven segment selection from long documents to build training data. The segment selector provides relevant samples with more accurate labels and non-relevant samples which are harder to be predicted. The experimental results show that the basic BERT-based ranker trained with the proposed segment selector significantly outperforms that trained by the heuristically selected segments, and performs equally to the state-of-the-art model with localized self-attention that can process longer input sequences. Our findings open up new direction to design efficient transformer-based rankers.

description: We present a gauge-field extension of the Bose condensate model that describes $T\approx0$ superfluid turbulence generated by the macroscopic motion of the superfluid. We first establish that the condensate model is dual to the short-range interacting loop gas model, wherein the loops represent quantum vortex lines. Vortex lines form, interact and proliferate as a result of the superfluid motion. Our extension is based on incorporating the Biot-Savart interaction between vortex lines, which is lacking in the loop gas model. We show that the extended loop gas is dual to a Ginzburg-Landau model, wherein the gauge coupling is between the macroscopic velocity field of the superfluid and the condensate. Applying the model to cylindrical and pipe flows, we describe how turbulence transitions with and without intermediate vortex flow, respectively.

description: We prove the analog of Kostant's Theorem on Lie algebra cohomology in the context of quantum groups. We prove that Kostant's cohomology formula holds for quantum groups at a generic parameter $q$, recovering an earlier result of Malikov in the case where the underlying semisimple Lie algebra $\mathfrak{g} = \mathfrak{sl}(n)$. We also show that Kostant's formula holds when $q$ is specialized to an $\ell$-th root of unity for odd $\ell \ge h-1$ (where $h$ is the Coxeter number of $\mathfrak{g}$) when the highest weight of the coefficient module lies in the lowest alcove. This can be regarded as an extension of results of Friedlander-Parshall and Polo-Tilouine on the cohomology of Lie algebras of reductive algebraic groups in prime characteristic.

description: Various approaches are reviewed that use scaled particle theories to describe dumbbell fluids made of tangent or overlapped hard spheres. Expressions encountered in the literature are written in a form similar to that presented in the thermodynamic perturbation theory introduced by Wertheim for chains and developed in statistical associating fluid theory (SAFT). Analogies and differences observed in these two types of theoretical descriptions allow one to propose alternative theoretical expressions to describe dumbbell fluids with overlapping spheres.

Recently, the game of disc golf has seen rapid growth, with a 55% increase in Professional Disc Golf Association (PDGA) memberships in 2021. Recent papers have predicted the dynamics of golf discs, such as the model from Giljarhus et al. (2022) but studies focusing on player performance have yet to be conducted. Sasakawa et al. (2017) compared ultimate forehand throws, a biomechanically similar action to forehand disc golf throws, from skilled and unskilled players. This abstract considers the performance characteristics of both backhand and forehand disc golf throws and relates them to player skill level.

description: Lunar hematite is formed by the oxidation of iron on the surface of the Moon by oxygen from the Earth's upper atmosphere. The Moon's surface is continuously affected by solar particles from the sun. However, Earth's magnetic tail blocks 99 % of the solar wind and provides windows of opportunity to transport oxygen from Earth's upper atmosphere to the Moon through magnetotail when it is in its full moon phase. Here, we propose to place a space weather observatory at the Earth-Moon L1 Lagrange point carrying a crucial payload onboard to study how Earth's magnetotail causes the Moon's surface to rust. The space weather observatory monitors the effect of Earth's magnetic field on the Moon using advanced spectroscopic sensors from Lagrange-based stations. Earth-moon L1 Lagrange point is the key location for space-weather observation as spacecraft near this point obtains a nearly unobstructed view of the moon. Numerical methods needed for a high-order analytical approximation have been implemented for more accurate predictions.

We show in particular that such corrections modify the holomorphic Yukawa couplings by an exponentially suppressed contribution, generically solving the Yukawa rank-one problem present in F-theory local models. We provide explicit expressions for the non-perturbative correction to the seven-brane superpotential, and check that it is related to a non-commutative deformation to the tree-level superpotential via the Seiberg-Witten map.

description: Blazars are variable targets in the sky, whose variation mechanism remains an open question. In this work, we make a comprehensive study on the variation phenomena of the spectral index and polarization degree (PD) to deeply understand the variation mechanism of B2 1633+382 (4C 38.41). We use the local cross-correlation function (LCCF) to perform the correlation analysis between multi-wavelength light curves. We find that both $γ$-ray and optical $V$-band are correlated with the radio 15 GHz at the beyond 3$σ$ confidence level. Based on the lag analysis, the emitting regions of $γ$-ray and optical locate at $14.2_{-2.4}^{+0}$ pc and $14.2_{-8.3}^{+8.3}$ pc upstream of the core region of radio 15 GHz, and are far away from the broad-line region (BLR). The broad lines in the spectrum indicate the existence of the accretion disk component in the radiation. Thus, we consider the two-component (TC) model, which includes the relative constant background component and the varying jet component to study the variation behaviors. The Markov Chain Monte Carlo (MCMC) procedure is adopted to study the physical parameters of the jet and the background components. To some extent, the study of normalized residuals indicates that the TC model fits better than the linear fitting model. The jet with helical magnetic field is hopeful to explain the variation, and the shock in jet model is not completely ruled out.

description: The work examines the issues of ensuring uniform hardness of coatings sprayed by a HVOF method onto parts complex-profile surfaces with their subsequent grinding. A formula is proposed on the basis of which the relationship between grinding modes and the final coatings hardness is assessed. Experimental studies were carried out to confirm the proposed theoretical relationship. Based on the research results, grinding modes were determined that ensure the coating final hardness greatest uniformity.

description: We have explored the phase behavior of a set of water-like models in slit pores of nanoscopic dimensions. The interaction between water and pore walls mimics the graphite surface. A version of density functional method is used as theoretical tools. The fluid models are adopted from the work of Clark et al. [Mol. Phys., 2006, 104, 3561]. They reproduce the bulk water vapor-liquid coexistence envelope adequately. Our principal focus is on changes of topology of the phase diagram of confined water and establishing trends of behavior of the crossover temperature between condensation and evaporation on the strength of water-graphite interaction potential. Growth of the water film on the pore walls is illustrated in terms of the density profiles. Theoretical results are discussed in context of computer simulation findings for water models in pores.

description: We extend the notion of Gibbsianness for mean-field systems to the set-up of general (possibly continuous) local state spaces. We investigate the Gibbs properties of systems arising from an initial mean-field Gibbs measure by application of given local transition kernels. This generalizes previous case-studies made for spins taking finitely many values to the first step in direction to a general theory, containing the following parts: (1) A formula for the limiting conditional probability distributions of the transformed system. It holds both in the Gibbs and non-Gibbs regime and invokes a minimization problem for a "constrained rate-function". (2) A criterion for Gibbsianness of the transformed system for initial Lipschitz-Hamiltonians involving concentration properties of the transition kernels. (3) A continuity estimate for the single-site conditional distributions of the transformed system. While (2) and (3) have provable lattice-counterparts, the characterization of (1) is stronger in mean-field. As applications we show short-time Gibbsianness of rotator mean-field models on the (q-1)-dimensional sphere under diffusive time-evolution and the preservation of Gibbsianness under local coarse-graining of the initial local spin space.

title: Some Advances in Bayesian Regression Problems
Creators: name: Prevenas, Sotirios
Publisher: name: University of Kent
Year: 2024

description: In the first part of the thesis, we propose a novel objective Bayesian method with an application in vector autoregressive models when the normal-Wishart prior, with ν degrees of freedom, is considered. In particular, we depart from the current approach of setting ν = m + 1 in the Wishart prior of an m−dimensional covariance matrix by setting a loss-based prior on ν. By doing so, we have been able to exploit any information about ν in the data and achieve better predictive performance than the method currently used in the literature. We show how this works well on both simulated and real data sets, where, in the latter case, we used data of macroeconometric nature as well as viral data. In addition, we explain why we believe we achieve better performance by showing that the data appear to suggest a value of ν far from the canonical m + 1 value. 

In the second part of the thesis, we introduce a variational Bayesian inference algorithm that performs variable selection in linear regression models. The algorithm is based on a combination of a spike-and-slab prior with a normal-gamma prior on the coefficients. The spike-and-slab prior is widely considered the “gold standard” for sparse Bayesian problems, and the normal-gamma prior is a hierarchical shrinkage prior that generalises the Bayesian LASSO. The algorithm also combines two types of updates, one for the initial iterations and one for the later ones. This hybrid updating scheme results in both high accuracy and speed of convergence. Simulations and real data examples demonstrate the competitiveness of the algorithm against recent variable selection methods. We also modify our method to perform variable selection on two types of generalised linear models.

description: Rare diseases are characterized by low prevalence and are often chronically debilitating or life-threatening. Imaging-based classification of rare diseases is challenging due to the severe shortage in training examples. Few-shot learning (FSL) methods tackle this challenge by extracting generalizable prior knowledge from a large base dataset of common diseases and normal controls, and transferring the knowledge to rare diseases. Yet, most existing methods require the base dataset to be labeled and do not make full use of the precious examples of the rare diseases. To this end, we propose in this work a novel hybrid approach to rare disease classification, featuring two key novelties targeted at the above drawbacks. First, we adopt the unsupervised representation learning (URL) based on self-supervising contrastive loss, whereby to eliminate the overhead in labeling the base dataset. Second, we integrate the URL with pseudo-label supervised classification for effective self-distillation of the knowledge about the rare diseases, composing a hybrid approach taking advantages of both unsupervised and (pseudo-) supervised learning on the base dataset. Experimental results on classification of rare skin lesions show that our hybrid approach substantially outperforms existing FSL methods (including those using fully supervised base dataset) for rare disease classification via effective integration of the URL and pseudo-label driven self-distillation, thus establishing a new state of the art.

Since there is no known analytic form of the Kaluza-Klein spectrum for our choice of geometry, we obtain a spectrum based on a combination of approximations and numerical computations. We study the possible signatures of our model for hadron colliders, especially the LHC, where the most important processes are the production of a graviton together with a hadronic jet or a photon. We find that for the case of hadronic jet production, it is possible to obtain relatively strong signals, while for the case of photon production, this is much more difficult.

Longshore currents in the vicinity of a breakwater
Creators: name: Daniel, Peter Edward
Publisher: name: University of British Columbia

description: Several theoretical models of the wave-induced current circulation in the vicinity of a breakwater extending from shore are presented. The models,which are patterned after a local field site, include several numerical models which take into account variable sea-floor topography and which compare the effects of linear and non-linear bottom friction as well as an analytical model characterized by semi-infinite beaches and uniform sea-floor topography. In general (for a given angle of wave incidence) the circulation patterns show two counter-rotating cells driven by wave-induced longshore currents which flow along both the breakwater and natural beaches toward their common intersection corner, with an offshore return flow in the form of a rip current. The qualitative features of the models are consistent with observations of sediment transport taken at the study site. Differences in the linear and non-linear bottom friction models do not become apparent until an off-shore trench parallel to the breakwater is introduced to the sea-floor topography. The non-linear model shows a deflection of the off-shore return flow into the trench in agreement with preliminary analysis based on a one-dimensional model. The linear results, however, differ considerably from those of the non-linear model and are difficult to interpret, showing an inordinate increase in transport over the trench. During the development of the analytical model difficulties were encountered due to the complexities of the analysis which necessitated that part of the solution be solved numerically. The results, while showing the same general features as the numerical models, exhibit a much more strongly divergent off-shore return flow. This difference, while unresolved, appears to be one of scale rather than of form.

description: Engineering of Sport 15 - Proceedings from the 15th International Conference on the Engineering of Sport (ISEA 2024)
Although there are many validation studies in sports engineering for computational fluid dynamics (CFD) simulations, there are few repeated studies and comparisons between different research groups. Common test cases for validation could strengthen the reliability and trust in CFD simulations, and help further develop the field. Examples of this from the aerospace and automotive industries are the AIAA CFD drag prediction workshop1 and the automotive CFD prediction workshop 2 , respectively. These initiatives use both simplified and realistic geometries. In this work, a simplified model representing an athlete’s head and torso is proposed for a similar initiative in sports engineering. The model is intended to be simple enough to allow efficient simulations and experiments, as well as featuring important flow phenomena in sports aerodynamics. The model should also be sufficiently generic to be representative for several sports disciplines. In addition to presenting the model, initial CFD simulations and wind tunnel experiments are presented.

description: This paper explores blackness as a provocation, a rupture at the heart of art’s polemic. It does not seek to be a thing, but a resonant force to proclaim a discourse of discovery for a new visual language. Theblackness is the expanse that the artist meanders through having neither a compass nor stars to navigate, marks an unheard refrain to try and state their territory.Any tool to measure the darkness implies there is something that can be defined, demarcated or discovered, as though darkness has a scale, size or shape. Darkness is not anything whilst being something, the infinitely smallest perturbation, energy shift, fluctuation that cannot be seen, to cause the disturbance for a recognition to take place.When images become saturated, blended and consumed in an ‘unregulated gluttony’ they produce darkness. It dwells in the collective unconsciousness: a dark, digital Eden ripe with uncertain potential. The search begins through the compression, like an allotrope of carbon, the future for the image world has to be discovered and encountered by moving through the darkness, enabling our senses, our proprioception to be able to accept the unacceptable, to deal with the unknowable. Commissioning our comprehension of position, momentum and equilibrium in the blackest of black forests to find alternative experiential references that channel us into a counter enlightenment.This paper focuses on the artist as a quantum flâneur, a prodigy of Lucretius falling through the vortices and laminar flows of darkness, waiting for the moment of the unpredictable swerve. Specific Artists whose work will be explored are Kasimir Malevich, Frederik de Wilde and Paul Thomas in the search for a new Eden.

A simple model for turbulence intermittencies based on self-avoiding random vortex stretching

description: Whether turbulence intermittencies shall be described by a log-Poisson, a log-stable pdf or other distributions is still debated nowadays. In this paper, a bridge between polymer physics, self-avoiding walk and random vortex stretching is established which may help in getting a new insight on this topics. Actually a very simple relationship between stability index of the stable law and the well known Flory exponent stemming from polymer physics is established. Moreover the scaling of turbulence intermittencies with Reynolds number is also obtained and the overall picture is very close to Tennekes' simple model for the fine scale structure of turbulence [Phys. Fluids, 11, 3 (1968)] : vortex tubes of Kolmogorov length width are bend by bigger vortices of Taylor length scale. This thus results in both a simple and sound model with no fitting parameter needed.

description: The Dark Eden conference comprised three stimulating days of key-note lectures and presentations by over sixty international professionals including creative arts practitioners, media artists, science and technology researchers, designers, curators, historians, critics and theorists, presenting new and innovative work exploring the theme of Dark Eden. Our distinguished keynote speakers Timothy Morton, Laura Marks and Barbara Bolt covered diverse topics such as beauty, cognition, freedom, media consumption, magic, performativity, matter, embodied imaging, contemporaneity and human and non-human agents, to touch lightly on their compelling provocations. Conference theme Is the Dark Eden a Counter-Enlightenment? Is it a shadow zone, a spectral landscape, a cemetery or a zombieland? Is it the debris of an image culture, or does it provide the material for a new culture? Eden was a mythical, bright paradise at the start of time—an original fullness of body and spirit, of image and substance, of nature and language—from which, so the myth goes, we have all been exiled for all of history. But, turning this story in reverse, what now might lie behind those closed gates of Eden, with its divine creator and caretaker absent, presumed dead? A garden gone to seed or a seething wilderness? An abandoned amusement park; a lost world? Or is it a derelict museum, shrouded in the darkness of disuse and of stagnant time? This is not just idle speculation. The cultural movement and moment now dubbed simply but absolutely as “Contemporary” is defined by the networked saturation of images: fullness, dissemination and inundation of frictionless image production, image hacking, image consumption and image commerce on social media and in platform capitalism; of 24/7 crisis news and uncritical web influencers; of CCTV and drone surveillance; of massive multiplayer online gaming; of “deepfake” hoaxes and simulations that augment reality and contribute to the relentlessly cynical campaigning of our 21st century political twitter “newspeak”. Is not this cornucopia and unprecedented availability of mediated imagery a kind of Eden? If so, it is a dark Eden, metaphorically fertile as a forest that is so thick with its tentacular edicts that any light that penetrates cannot escape its web; or perhaps, that its mutated growth is now dependent on a black rather than bright light. Its darkness might be that of the pall of ash-filled smoke shrouding a burning continent.
Conformal generally covariant quantum field theory: The scalar field and its Wick products

description: In this paper we generalize the construction of generally covariant quantum theories given in the work of Brunetti, Fredenhagen and Verch to encompass the conformal covariant case. After introducing the abstract framework, we discuss the massless conformally coupled Klein Gordon field theory, showing that its quantization corresponds to a functor between two certain categories. At the abstract level, the ordinary fields, could be thought as natural transformations in the sense of category theory. We show that, the Wick monomials without derivatives (Wick powers), can be interpreted as fields in this generalized sense, provided a non trivial choice of the renormalization constants is given. A careful analysis shows that the transformation law of Wick powers is characterized by a weight, and it turns out that the sum of fields with different weights breaks the conformal covariance. At this point there is a difference between the previously given picture due to the presence of a bigger group of covariance. It is furthermore shown that the construction does not depend upon the scale mu appearing in the Hadamard parametrix, used to regularize the fields. Finally, we briefly discuss some further examples of more involved fields.

About inevitability of budgetary code receiving for fiscal politics

description: Since the end of 90s till today when all the elements confirming Georgian State System have practically been established, budget system and policy remains as the most difficult Georgian macroeconomics challenge and even still half-and-half unsolved problem. One side of the fiscal policy is quite crucially formulated and administrative Tax Code, and the other side is the weak, unmanaged and incomplete law on Budget System. According to the above-mentioned the elaboration and adoption of the Budget Code having equal force as Tax Code is necessary by which the following are to be determined: excellence of government responsibility when it will not perform the budget obligations specified by the law permanently; the rights and responsibilities of the state, the optimal distribution of the funds mobilized by the tax towards each member of the society. For optimization of the budget system effective correlation between the state, regional and local budgets revenues and expenditures is particularly important as the social-economic development of the regions and territorial units of the country is impossible without the financial relations. For it the just differentiation of tax base in the section of state, regional and local budgets and transfers system for support of the budgets of the territorial units from the central budget are necessary. Solving the most part of these problems is possible by the adoption of the budget code which, in our opinion, is to be considered as the closest decisive task for the current legislative and executive authority.

description: A legacy of Dark Edens flail within our attempts to synthetically manipulate nature, acting like transport proteins in a cell membrane that allow infiltration of both good and evil to emerge in contemporary imaginings of self and other.In trying to trace the steps of how a virus can jump species and achieve word-wide proliferation, we set out to establish both scientific and philosophical phylogenetic trees that will allow us to point backwards to a visualized emergence point. And in our pointing, both cultural and biological lines of transgressions maneuver on tracks within our cellular and granular memories akin to lysosomes traveling along microtubular pathways attempting to dispose of our complicitness.In striving to determine the proximal origin of the SARS-CoV-2 virus, we examine intersections of geographic location, time points and mutation rates of specimens to elucidating common ancestry and species divergence. But in our origin stories, both moral and aesthetic judgements lurk in the telling.Speculations are being made as to whether the virus has a known backbone, how cell passaging allows for rapid mutation and adaptation, what circumstances facilitate modifications that enable viral species jumping, and how viral taxonomy defines “novelty” and “species demarkation.”As culture is pipetted out both “within” and “against” nature, how do we listen to signaling cells and the soft noise of aesthetic markers in ecosystems that allow us to hear when we are too immersed, too close and in need to stepping back?

description: There is hype around the idea of ‘darkness’ as the inverse to capitalism’s ‘daylight’ world: one of relentless activity and glare. One major player in the race to delineate the characteristics of this inverse world is the Dark Sky movement, which harnesses collective desire for a ‘break’ from capitalism by characterizing darkness as a spatio-temporal zone of pause, in which it is possible to reconnect with the ‘universal’ qualities of nature. Charting overlaps in the discussions surrounding 'darkness' and the Covid-19 lockdown period (also figured as a space of pause), this presentation will highlight the need to intervene in the Dark Sky movement’s mega-narrative on several grounds. Firstly: it creates a space in which the qualities associated with the capitalist day are perfectly mirrored and inverted. In doing so, it reinforces the existing order, grouping anything that does not ‘fit’ with capitalisms diurnal rhythm into a ‘dark’ realm, and thus entrenching the binaries by which neoliberal capitalism retains its hegemony. Secondly, it figures ‘night’ as a space outside of power, an empty viewing room for the spectacle of the stars, in the face of which spectators ‘dissolve’ and cease to exist as relational beings. Finally, it ignores the fact that the world after dark is in many ways one of heightened surveillance and militarism. This presentation will make a case for a way of ‘seeing’ dark landscapes as no less complex than daytime ones, made up of relational networks and constantly shifting arrangements of power.

description: We consider one-dimensional substitution tiling spaces where the dilatation (stretching factor) is a degree d Pisot number, and where the first rational Cech cohomology is d-dimensional. We construct examples of such "homological Pisot" substitutions that do not have pure discrete spectra. These examples are not unimodular, and we conjecture that the coincidence rank must always divide a power of the norm of the dilatation. To support this conjecture, we show that homological Pisot substitutions exhibit an Exact Regularity Property (ERP), in which the number of occurrences of a patch for a return length is governed strictly by the length. The ERP puts strong constraints on the measure of any cylinder set in the corresponding tiling space.
