description: Reinforcement Learning agents are expected to eventually perform well. Typically, this takes the form of a guarantee about the asymptotic behavior of an algorithm given some assumptions about the environment. We present an algorithm for a policy whose value approaches the optimal value with probability 1 in all computable probabilistic environments, provided the agent has a bounded horizon. This is known as strong asymptotic optimality, and it was previously unknown whether it was possible for a policy to be strongly asymptotically optimal in the class of all computable probabilistic environments. Our agent, Inquisitive Reinforcement Learner (Inq), is more likely to explore the more it expects an exploratory action to reduce its uncertainty about which environment it is in, hence the term inquisitive. Exploring inquisitively is a strategy that can be applied generally; for more manageable environment classes, inquisitiveness is tractable. We conducted experiments in "grid-worlds" to compare the Inquisitive Reinforcement Learner to other weakly asymptotically optimal agents.

description: The structural energetics of PdTi and PtTi have been studied using first-principles density-functional theory with pseudopotentials and a plane-wave basis. We predict that in both materials, the experimentally reported orthorhombic $B19$ phase will undergo a low-temperature phase transition to a monoclinic $B19'$ ground state. Within a soft-mode framework, we relate the $B19$ structure to the cubic $B2$ structure, observed at high temperature, and the $B19'$ structure to $B19$ via phonon modes strongly coupled to strain. In contrast to NiTi, the $B19$ structure is extremely close to hcp. We draw on the analogy to the bcc-hcp transition to suggest likely transition mechanisms in the present case.

description: Understanding the mapping between stimulus, behavior, and neural responses is vital for understanding sensory, motor, and general neural processing. We can examine this relationship through the complementary methods of encoding (predicting neural responses given the stimulus) and decoding (reconstructing the stimulus given the neural responses). The work presented in this thesis proposes, evaluates, and analyzes several nonlinear approaches for encoding and decoding that leverage recent advances in machine learning to achieve better accuracy. We first present and analyze a recurrent neural network encoding model to predict retinal ganglion cell responses to natural scenes, followed by a decoding approach that uses neural networks for approximate Bayesian decoding of natural images from these retinal cells. Finally, we present a probabilistic framework to distill behavioral videos into useful low-dimensional variables and to decode this behavior from neural activity.

description: This study provides a performance comparison of arsenic, cadmium and zinc treatment at mildly acid to neutral pH in an anaerobic bioreactor (ABR) column experiment operated at 4°C and 25°C. The materials and contaminants were based on a field scale system operated by Nature Works Remediation Corp. for Teck Cominco Metals Ltd. in Trail, BC. The majority of arsenic was removed within the oxic zones of the ABR columns. Although it was thought that arsenic removal at this stage was attributed to sorption to iron, it is now known to be zinc arsenate. The work showed cadmium and zinc removal improved in relation to the extent of anoxic conditions in the columns. In the most anaerobic zone of the columns (i.e., characterized by good sulphate reducing bacteria (SRB) activity) effective zinc removal required a stable SRB population, but was not necessarily temperature dependent. However, there was a direct and significant impact to microbial activity as a result of a temperature change. The work suggested that internal monitoring of DO and SRB can provide valuable information with respect to significant metal removal mechanisms, and the active volume in which metal sulphides can be significantly generated. The information can be used to: troubleshoot an under-performing system, and make appropriate amendments to improve system performance.

description: The solar cycle is the cyclic variation of solar activity, with a span of 9-14 years. The prediction of the solar cycle is an important and unsolved problem with implications for communications, aviation and other aspects of our high-tech society. Our interest is model-based prediction, and we present a self-consistent procedure for parameter estimation and model state estimation, even when only one of several model variables can be observed.
Data assimilation is the art of comparing, combining and transferring observed data into a mathematical model or computer simulation. We use the 3DVAR methodology, based on the notion of least squares, to present an implementation of a traditional data assimilation. Using the Shadowing Filter - a recently developed method for nonlinear data assimilation - we outline a path towards model based prediction of the solar cycle. To achieve this end we solve a number of methodological challenges related to unobserved variables. We also provide a new framework for interpretation that can guide future predictions of the Sun and other astrophysical objects.

description: This brief essay is a translation of the introduction to the volume L’Eros in Shakespeare, edited by Alessandro Serpieri and Keir Elam in 1988. In discussing the role of the passions in Shakespeare’s plays and poetry, it brings together considerations from semiotics, psychoanalysis, drama theory and early modern English history. These approaches are all pertinent to the analysis of the multi-perspective and performative language of Shakespeare’s plays. The essay also surveys the four Shakespeare conferences held in Taormina, under the direction of Alessandro Serpieri, between 1984 and 1987.

description: High-multiplicity all-hadronic final states are an important, but difficult final state for searching for physics beyond the Standard Model. A powerful search method is to look for large jets with accidental substructure due to multiple hard partons falling within a single jet. One way for estimating the background in this search is to exploit an approximate factorization in quantum chromodynamics whereby the jet mass distribution is determined only by its kinematic properties. Traditionally, this approach has been executed using histograms constructed in a background-rich region. We propose a new approach based on Generative Adversarial Networks (GANs). These neural network approaches are naturally unbinned and can be readily conditioned on multiple jet properties. In addition to using vanilla GANs for this purpose, a modification to the traditional WGAN approach has been investigated where weight clipping is replaced with a naturally compact set (in this case, the circle). Both the vanilla and modified WGAN approaches significantly outperform the histogram method, especially when modeling the dependence on features not used in the histogram construction. These results can be useful for enhancing the sensitivity of LHC searches to high-multiplicity final states involving many quarks and gluons and serve as a useful benchmark where GANs may have immediate benefit to the HEP community.

description: Microfludic channels are now a well established platform for many purposes, including bio-medical research and Lab on a Chip applications. However, the nature of flow within these channels is still unclear. There is evidence that the mean drift velocity in these channels deviates from the regular Navier-Stokes solution with `no slip' boundary conditions. Understanding these effects, is not only of value for fundamental fluid mechanics interest, but it also has practical importance for the future development of microfluidic and nanofludic infrastructures. We propose a nano-NMR based setup for measuring the drift velocity near the surface of a microfludic channel in a non-intrusive fashion. We discuss different possible protocols, and provide a detailed analysis of the measurement's sensitivity in each case. We show that the nano-NMR scheme outperforms current fluorescence based techniques.

description: It has been recognized recently that fractional calculus is useful for handling scaling structures and processes. We begin this survey by pointing out the relevance of the subject to physical situations. Then the essential definitions and formulae from fractional calculus are summarized and their immediate use in the study of scaling in physical systems is given. This is followed by a brief summary of classical results. The main theme of the review rests on the notion of local fractional derivatives. There is a direct connection between local fractional differentiability properties and the dimensions/ local Holder exponents of nowhere differentiable functions. It is argued that local fractional derivatives provide a powerful tool to analyse the pointwise behaviour of irregular signals and functions.

Closure of the Colomac Mine : a First Nations - mine owner collaboration
Creators: name: Pearse, Anthony Dalton, 1946-
Publisher: name: The University of British Columbia
Year: 2009

description: The reclamation of mines is an important issue for Aboriginal peoples in Canada who have mines in their traditional territories. Mine owners and operators have a responsibility to engage those First Nation communities affected by these projects in decisions relating to land use and environment including, particularly, mine site reclamation and closure. Decisions must be made that consider legal and policy requirements, scientific and technical standards and practices, traditional knowledge and cultural values. Closure planning for the abandoned Colomac gold mine in the Northwest Territory represents a successful collaborative planning and decision-making process that evolved from a partnership between the Tlicho First Nation (formerly known as the Dogrib Treaty 11 Council) and the federal Department of Indian Affairs and Northern Development (DIAND) as owner of the site. DIAND and the Tlicho pioneered a joint working relationship to research potential options for closure, and to establish a means whereby each partner was able to use its values and priorities to systematically assess project risks and to ultimately select a preferred closure option. Although the process encountered many challenges, the mine closure plan resulting from the process ultimately met the needs of both partners. The key ingredients for success included early and meaningful involvement of the Tlicho communities in the closure planning, and the provision of resources to enable them to do so.

description: A key issue of cognitive diagnostic models (CDMs) is the correct identification of Q-matrix which indicates the relationship between attributes and test items. Previous CDMs typically assumed a known Q-matrix provided by domain experts such as those who developed the questions. However, misspecifications of Q-matrix had been discovered in the past studies. The primary purpose of this research is to set up a mathematical framework to estimate the true Q-matrix based on item response data. The model considers all Q-matrix elements as parameters and estimates them through EM algorithm. Two simulation designs are conducted to evaluate the feasibility and performance of the model. An empirical study is addressed to compare the estimated Q-matrix with the one designed by experts. The results show that the model performs well and is able to identify 60% to 90% of correct elements of Q-matrix. The model also indicates possible misspecifications of the designed Q-matrix in the fraction subtraction test.

description: In 1993, a proof was published, within ``Classical and Quantum Gravity,'' that there are no regular solutions to the {\it linearized} version of the twisting, type-N, vacuum solutions of the Einstein field equations. While this proof is certainly correct, we show that the conclusions drawn from that fact were unwarranted, namely that this irregularity caused such solutions not to be able to truly describe pure gravitational waves. In this article, we resolve the paradox---since such first-order solutions must always have singular lines in space for all sufficiently large values of $r$---by showing that if we perturbatively iterate the solution up to the third order in small quantities, there are acceptable regular solutions. That these solutions become flat before they become non-twisting tells us something interesting concerning the general behavior of solutions describing gravitational radiation from a bounded source.

description: Image representations are commonly learned from class labels, which are a simplistic approximation of human image understanding. In this paper we demonstrate that transferable representations of images can be learned without manual annotations by modeling human visual attention. The basis of our analyses is a unique gaze tracking dataset of sonographers performing routine clinical fetal anomaly screenings. Models of sonographer visual attention are learned by training a convolutional neural network (CNN) to predict gaze on ultrasound video frames through visual saliency prediction or gaze-point regression. We evaluate the transferability of the learned representations to the task of ultrasound standard plane detection in two contexts. Firstly, we perform transfer learning by fine-tuning the CNN with a limited number of labeled standard plane images. We find that fine-tuning the saliency predictor is superior to training from random initialization, with an average F1-score improvement of 9.6% overall and 15.3% for the cardiac planes. Secondly, we train a simple softmax regression on the feature activations of each CNN layer in order to evaluate the representations independently of transfer learning hyper-parameters. We find that the attention models derive strong representations, approaching the precision of a fully-supervised baseline model for all but the last layer.

description: Stochastic partial differential equations arise when modelling uncertain phenomena. Here the emphasis is on uncertain systems where the randomness is spatial. In contrast to traditional slow computational approaches like Monte Carlo simulation, the methods described here can be orders of magnitude more efficient. These more recent methods are based on some kind stochastic Galerkin approximations, approximating the unknown quantities as functions of independent random variables, hence the name "white noise analysis". We outline the steps leading to the fully discrete equations, commenting on one possible numerical solution method. Key to many of the developments is tensor product structure of the solution, which must be exploited both theoretically and numerically. For two examples with polynomial non-linearities the computations are shown to be quite explicit and can be performed largely analytically.

description: We investigate the quantum conformal algebras of N=2 and N=1 supersymmetric gauge theories. Phenomena occurring at strong coupling are analysed using the Nachtmann theorem and very general, model-independent, arguments. The results lead us to introduce a novel class of conformal field theories, identified by a closed quantum conformal algebra. We conjecture that they are the exact solution to the strongly coupled large-N_c limit of the open conformal field theories. We study the basic properties of closed conformal field theory and work out the operator product expansion of the conserved current multiplet T. The OPE structure is uniquely determined by two central charges, c and a. The multiplet T does not contain just the stress-tensor, but also R-currents and finite mass operators. For this reason, the ratio c/a is different from 1. On the other hand, an open algebra contains an infinite tower of non-conserved currents, organized in pairs and singlets with respect to renormalization mixing. T mixes with a second multiplet T* and the main consequence is that c and a have different subleading corrections. The closed algebra simplifies considerably at c=a, where it coincides with the N=4 one.

description: This paper explores the use of a cumulant method to determine the zeros of partition functions for continuous phase transitions. Unlike a first-order transition, with a uniform density of zeros near the transition point, a continuous transition is expected to show a power law dependence of the density with a nontrivial slope for the line of zeros. Different types of models and methods of generating cumulants are used as a testing ground for the method. These include exactly solvable DNA melting problem on hierarchical lattices, heterogeneous DNA melting with randomness in sequence, Monte Carlo simulations for the well-known square lattice Ising model. The method is applicable for closest zeros near the imaginary axis, as these are needed for dynamical quantum phase transitions. In all cases, the method is found to provide the basic information about the transition, and most importantly, avoids root finding methods.

description: As alternatives to partial differential equations (PDEs), nonlocal continuum models given in integral forms avoid the explicit use of conventional spatial derivatives and allow solutions to exhibit desired singular behavior. As an application, peridynamic models are reformulations of classical continuum mechanics that allow a natural treatment of discontinuities by replacing spatial derivatives of stress tensor with integrals of force density functions.
      The thesis is concerned about the mathematical perspective of nonlocal modeling and local-nonlocal coupling for fracture mechanics both theoretically and numerically. To this end, the thesis studies nonlocal diffusion models associated with ``Neumann-type'' constraints (or ``traction conditions'' in mechanics), a nonlinear peridynamic model for fracture mechanics with bond-breaking rules, and a multi-scale model with local-nonlocal coupling.
      In the computational studies, it is of practical interest to develop robust numerical schemes not only for the numerical solution of nonlocal models, but also for the evaluation of suitably defined derivatives of solutions. This leads to a posteriori nonlocal stress analysis for structure mechanical models.

description: The proposed study explores the experiences of nonnative speakers when they interact with native speakers in conflict situations.  The aim of the study is to test if nonnative speakers experience stereotype threat when interacting with native speakers in conflict situations and, if so, to examine how stereotype threat affects their regulatory focus, conflict behaviors, and outcomes.  A serial mediation model with three mediators (stereotype threat, regulatory focus, conflict behaviors) will be tested. This study contributes to the field of organizational psychology and conflict studies by 1) extending stereotype threat literature and examining nonnative speakers as a social identity group that experiences stereotype threat, 2) exploring the effects of stereotype threat in a conflict context, and 3) extending workforce diversity literature and examining language diversity in relation to conflict-related behaviors and outcomes in organizational settings.  The findings from the proposed study offer insights into understanding the effects of language diversity on conflict dynamics within the increasingly globalized, multi-cultural world of organizations.
Thermodynamics of Decaying Vacuum Cosmologies

Publisher: name: arXiv
Year: 1996
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The thermodynamic behavior of vacuum decaying cosmologies is investigated within a manifestly covariant formulation. Such a process corresponds to a continuous irreversible energy flow from the vacuum component to the created matter constituents. It is shown that if the specific entropy per particle remains constant during the process, the equilibrium relations are preserved. In particular, if the vacuum decays into photons, the energy density $ρ$ and average number density of photons $n$ scale with the temperature as $ρ\sim T^{4}$ and $n \sim T^{3}$. The temperature law is determined and a generalized Planckian type form of the spectrum, which is preserved in the course of the evolution, is also proposed. Some consequences of these results for decaying vacuum FRW type cosmologies as well as for models with ``adiabatic'' photon creation are discussed.

description: Nonlocal phenomena are ubiquitous in nature. The nonlocal models investigated in this thesis use integration in replace of differentiation and provide alternatives to the classical partial differential equations. The nonlocal interaction kernels in the models are assumed to be as general as possible and usually involve finite range of nonlocal interactions. Such settings on one hand allow us to connect nonlocal models with the existing classical models through various asymptotic limits of the modeling parameter, and on the other hand enjoy practical significance especially for multiscale modeling and simulations.
      To make connections with classical models at the discrete level, the central theme of the numerical analysis for nonlocal models in this thesis concerns with numerical schemes that are robust under the changes of modeling parameters, with mathematical analysis provided as theoretical foundations. Together with extensive discussions of linear nonlocal diffusion and nonlocal mechanics models, we also touch upon other topics such as high order nonlocal models, nonlinear nonlocal fracture models and coupling of models characterized by different scales.

 Remarks. Bates (1892) described Anatinomma to include his new species A. alveolatum. The second part of the generic name, the Greek word “ ὄμμᾰ” (ómma), means “eyes.” According to ICZN (1999: Article 30.1.2), “a genus-group name that is or ends in a Greek word transliterated into Latin without other changes, takes the gender given for that word in standard Greek dictionaries.” As “ómma” is neuter gender, two species-group names need to be corrected: A. brevicornis Fisher, 1944, becomes A. brevicorne; and A. insularis Chemsak and Linsley, 1964, becomes A. insulare.

description: Kerr frequency combs enable compact and robust platforms for applications such as data communications and spectroscopy. Initial demonstrations used dissipative soliton combs operating in the anomalous group velocity dispersion (GVD) regime to illustrate the promising capabilities of Kerr-comb-based technologies. However, many real-world applications, such as wavelength division multiplexing and LiDAR, benefit from higher comb-line powers that are inherently inaccessible to Kerr frequency combs. Nevertheless, nonsolitonic Kerr combs operating in the normal GVD regime offer promise as a platform for the integration of such applications due to their ability to easily access high pump-to-comb conversion efficiencies and spectral profiles with slower power falloffs. Unlike a dissipative Kerr soliton which is a single cycle periodic pattern on top of a homogenous background, a nonsolitonic Kerr comb arises through the interlocking of two switching waves of opposite polarity, each of which connects the two homogenous state solutions of the bistable cavity response. Here, we present a systematic approach for turn-key generation of Kerr combs in the normal GVD regime. We use a coupled ring geometry to induce and control avoided mode crossings for the generation of low-noise frequency combs with conversion efficiencies of up to 57%. Moreover, we explore the regime of synchronization for these nonsolitonic Kerr combs. Synchronization is a universal mechanism of coupled nonlinear oscillators that manifests itself as the spontaneous appearance of order within nature's tendency for disorder and chaos. It is a process by which the natural rhythms of interacting oscillators adjust to a common frequency and produce a mutually phase-locked state. In the realm of Kerr frequency combs, synchronization allows for the repetition rates, or equivalently the comb-line spacings, of individual Kerr combs to become identical. We reveal the universality of Kerr comb synchronization by synchronizing two nonsolitonic Kerr combs and thereby extending the scope of synchronization beyond the soliton regime. Furthermore, we introduce a method to overcome the inherently low output power of Kerr combs while maintaining the high conversion efficiency of a normal GVD Kerr comb. We demonstrate efficient comb-line power enhancement by coherently combining two nonsolitonic Kerr combs via on-chip synchronization. Our on-chip synchronization design removes the requirement for dispersion compensation of the coupling signal while increasing the overall stability of the system. Our techniques of comb generation, synchronization, and coherent combining enable nonsolitonic Kerr combs as a platform to achieve a fully integrated, high-power Kerr comb source.
Collaborating with Euripides: Actors and Scholars Improve the Drama Text
Creators: name: Avezzù, Guido
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2018

description: This article examines a passage from Euripides’ Electra which has been suspected of being textually interpolated. It is a fairly long passage, covering twenty-six lines out of overall fourty-four, between 357 and 400. Through an analysis of the cotextual and contextual consistency of the suspect portions, the article wishes to demonstrate that the scene under scrutiny, which shows no trace of incongruous additions, is coherent with the overall play text Electra as it has been passed down to us under Euripides’ name.

Excavations Inside Harting Beacon Hill-Fort, West Sussex, 1976
Creators: name: Bedwin, Owen
Publisher: name: Archaeology Data Service
Year: 2021

description: Sussex Archaeological Collections, 116, 225-240
description: An area of 1,300 square metres was excavated inside Harting Beacon, and a section was cut through the defences. Early Iron Age pottery was found, dating to the sixth and fifth centuries B.C. Within the excavated area, 4 four-post-hole structures and one six-post-hole structure were found, plus three small pits and a circular barrow. The central burial of this barrow had been robbed out, but a Son date seems possible.
Onstage/Offstage (Mis)Recognitions in The Winter’s Tale
Creators: name: Bigliazzi, Silvia
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2018

description: How do the offstage and the narrative mode contribute to the construction of knowledge in The Winter’s Tale, making it perspectival and situated? This article discusses how not two, but three recognition scenes interact, bringing together the play’s first and second part, by enhancing the role of the offstage/onstage dialectic, both within each one of these three scenes, and in their mutual dialogue. This reading relies upon an interpretation of the play’s overall signifying system, based upon a principle of correspondences tying together the fabric of drama at different levels: lexical, performative, thematic, conceptual. It shows how foregrounded patterns of iteration dependent on the criterion of likeness do not make for stable significance outside of the realm of art (or artifice). Instead, they appear to be a possibly self-deluding response to a troubled awareness of the unreliability of signs and appearances, betraying concern about the (potentially tragic) inevitability of doubt.

description: Monopoles and solitons have important topological aspects like quantized fluxes, winding numbers and curved target spaces. Naive discretizations which substitute a lattice of points for the underlying manifolds are incapable of retaining these features in a precise way. We study these problems of discrete physics and matrix models and discuss mathematically coherent discretizations of monopoles and solitons using fuzzy physics and noncommutative geometry. A fuzzy sigma-model action for the two-sphere fulfilling a fuzzy Belavin-Polyakov bound is also put forth.

description: The algebraic structure and the relationships between the eigenspaces of the Calogero-Sutherland model (CSM) and the Sutherland model (SM) on a circle are investigated through the Cherednik operators. We find an exact connection between the simultaneous non-symmetric eigenfunctions of the $A_{N-1}$ Cherednik operators, from which the eigenfunctions of the CSM and SM are constructed, and the monomials. This construction, not only, allows one to write down a harmonic oscillator algebra involving the Cherednik operators, which yields the raising and lowering operators for both of these models, but also shows the connection of the CSM with free oscillators and the SM with free particles on a circle. We also point out the subtle differences between the excitations of the CSM and the SM.

Epic-Oracular Markedness in Fifth-Century BCE Greek Comic Fragments
Creators: name: Novokhatko, Anna
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2018

description: The function of register features and linguistic indicators for epic (phonemes, morphemes, lexemes, syntactic structures, formulas, metre, narrative outset) in fragments of Sicilian and Old Attic comedy constitute the subject of this paper. Decoding epic-oracular register in comedy contributes to the reading of the fragmentary text. This is particularly significant in the lack of an explanatory context. The conscious juxtaposition of epic and comic registers and patterns by comedians can be thought of as a parodic game creating comic dissonance; but comic texts also reflect discourses on genre indicators of the time and should thus be considered in the larger framework of the development of Greek philological thought.

description: We observe the dynamic formation of $Cs_2$ molecules near Feshbach resonances in a cold sample of atomic cesium using an external probe beam. This method is 300 times more sensitive than previous atomic collision rate methods, and allows us to detect more than 20 weakly-coupled molecular states, with collisional formation cross sections as small as $σ=3\times 10^{-16}$cm$^2$. We propose a model to describe the atom-molecule coupling, and estimate that more than $2 \times 10^5$ $Cs_2$ molecules coexist in dynamical equilibrium with $10^8$ $Cs$ atoms in our trap for several seconds.
Cosmologies with Photon Creation and the 3K Relic Radiation Spectrum

description: A new Planckian distribution for cosmologies with photon creation is derived using thermodynamics and semiclassical considerations. This spectrum is preserved during the evolution of the universe and compatible with the present spectral shape of the cosmic microwave background radiation(CMBR). Accordingly, the widely spread feeling that cosmologies with continuous photon creation are definitely ruled out by the COBE limits on deviation of the CMBR spectrum from blackbody shape should be reconsidered. It is argued that a crucial test for this kind of cosmologies is provided by measurements of the CMBR temperature at high redshifts. For a given redshift $z$ greater than zero, the temperature is smaller than the one predicted by the standard FRW model.

description: In continuum physics, there are important topological aspects like instantons, theta-terms and the axial anomaly. Conventional lattice discretizations often have difficulties in treating one or the other of these aspects. In this paper, we develop discrete quantum field theories on fuzzy manifolds using noncommutative geometry. Basing ourselves on previous treatments of instantons and chiral fermions (without fermion doubling) on fuzzy spaces and especially fuzzy spheres, we present discrete representations of theta-terms and topological susceptibility for gauge theories and derive axial anomaly on the fuzzy sphere. Our gauge field action for four dimensions is bounded by the modulus of the instanton number as in the continuum.
