description: We introduce an algebraic framework for interacting quantum systems that enables studying complex phenomena, characterized by the coexistence and competition of various broken symmetry states of matter. The approach unveils the hidden unity behind seemingly unrelated physical phenomena, thus establishing exact connections between them. This leads to the fundamental concept of {\it universality} of physical phenomena, a general concept not restricted to the domain of critical behavior. Key to our framework is the concept of {\it languages} and the construction of {\it dictionaries} relating them.

description: The thermal evolution of hypernuclear compact stars is studied for stellar models constructed on the basis of covariant density functional theory in Hartree and Hartree-Fock approximation. Parametrizations of both types are consistent with the astrophysical mass constraints on compact stars and available hypernuclear data. We discuss the differences of these density functionals and highlight the effects they have on the composition and on the cooling of hypernuclear stars. It is shown that hypernuclear stars computed with density functional models that have a low symmetry energy slope, $L$, are fairly consistent with the cooling data of observed compact stars. The class of stellar models based on larger $L$ values gives rise to the direct Urca process at low densities, which leads to significantly faster cooling. We conjecture high-density pairing for protons and $Λ$'s in the $P$-wave channel and provide simple scaling arguments to obtain these gaps. As a consequence the most massive stellar models with masses $1.8 \le M/M_{\odot} \le2$ experience slower cooling by hyperonic dUrca processes which involve $Λ$'s and protons.

Neurons in Cat Primary Visual Cortex cluster by degree of tuning but not by absolute spatial phase or temporal response phase

description: Neighboring neurons in cat primary visual cortex (V1) have similar preferred orientation, direction, and spatial frequency. How diverse is their degree of tuning for these properties? Are they also clustered in their tuning for the spatial phase of a flashed grating ("absolute spatial phase") or the temporal phase of a drifting grating ("temporal response phase")? To address these questions, we used tetrode recordings to simultaneously isolate multiple cells at single recording sites and record their responses to flashed and drifting gratings of multiple orientations, spatial frequencies, and spatial/temporal phases. We recorded the responses of 761 cells presented with drifting gratings and 409 cells presented with flashed gratings. We found that orientation tuning width, spatial frequency tuning width and direction selectivity index all showed significant clustering. Absolute spatial phase and temporal response phase, however, showed no clustering. We also present an algorithm that improves the performance of spike-sorting algorithms, for use in analyzing cells recorded using tetrodes. A cluster of spikes corresponding to a putative cell obtained through automatic or manual spike sorting algorithms may contain spikes from other cells with similarly-shaped waveforms. Our algorithm preferentially removes contaminating spikes from other cells, thereby decreasing the level of contamination of each unit. We call this procedure "pruning", as it entails removing portions of the cluster that are determined to be more likely to contain contaminating spikes than the cluster as a whole. Testing of the algorithm on data in which "ground truth" is known shows excellent performance, for example on average giving a percentage reduction in false positive spikes 8.2 times the percentage reduction in true positive spikes, and reducing the degree of contamination by an average of about 13%.
Neuropsychological Test Performance and Other Predictors of Adult Outcome in a Prospective Follow-Up Study of Children with ADHD

Subjects: Clinical psychology

description: The present research is a prospective follow-up study which investigates the neuropsychological test performance of children with Attention Deficit/Hyperactivity Disorder (ADHD) and examines whether test performance and severity of childhood disruptive behaviors predict adult psychiatric status and functioning in major domains (educational, social, and occupational). Participants were 100 middle-class, White boys (mean age = 9) of average intelligence diagnosed with ADHD without comorbid conduct disorder (CD) diagnoses. Childhood predictors were teacher behavioral ratings and performance on a variety of neuropsychological tests. Participants were later assessed at mean age 25 by clinicians blind to childhood status. Linear and logistic regression analyses were used to determine the impact of childhood predictor variables on adult outcome. Results showed no significant impairment on measures of neuropsychological functioning, nor was neuropsychological test performance generally correlated with severity of disruptive behaviors. ADHD boys with low ratings of conduct disorder behaviors (not at all, just a little) demonstrated lower verbal ability than those without CD behaviors. Severity of childhood CD behaviors emerged as the most consistent predictor of adult functioning and prevalence of psychiatric disorders. Measures of working memory and attention (Working Memory Index and Freedom from Distractibility Factor of the WISC-R) inconsistently predicted functioning in some areas, although this may reflect the well-known relationship between childhood IQ and later adult functioning. Taken together, the findings suggest that in boys with ADHD who are of average intelligence and have intact neuropsychological functioning, even low levels of CD behaviors are associated with poor prognosis in adulthood.

description: The interaction of the benzimidazolium salt with Ag2O in dichloromethane to prepare novel Ag(I)-N-heterocyclic carbene complexes has been carried out at room temperature for 48 h in the absence of light. The obtained complexes were identified and characterized by 1H and 13C NMR, FT-IR and elemental analysis techniques. In addition, it has been found that some of the complexes are antimicrobially active and show higher activity than the free ligand. Probably metal chelation affects significantly the antimicrobial behavior of the ligands. The minimum inhibitory concentration of the complexes was determined. The results indicated that these complexes exhibit antimicrobial activity.

description: Solvable vertex models in a ferromagnetic regime give rise to soliton cellular automata at q=0. By means of the crystal base theory, we study a class of such automata associated with the quantum affine algebra U_q(g_n) for non exceptional series g_n = A^{(2)}_{2n-1}, A^{(2)}_{2n}, B^{(1)}_n, C^{(1)}_n, D^{(1)}_n and D^{(2)}_{n+1}. They possess a commuting family of time evolutions and solitons labeled by crystals of the smaller algebra U_q(g_{n-1}). Two-soliton scattering rule is identified with the combinatorial R of U_q(g_{n-1})-crystals, and the multi-soliton scattering is shown to factorize into the two-body ones.

description: In this work, we report the lattice calculation of two important quantities which emerge from second order, K0 − ¯ K0 mixing : ∆MK and K. The RBC-UKQCD collaboration has performed the ﬁrst calculation of ∆MK with unphysical kinematics [1]. We now extend this calculation to near-physical and physical ensembles. In these physical or near-physical calculations, the two-pion energies are below the kaon threshold, and we have to examine the two-pion intermediate states contribution to ∆MK, as well as the enhanced ﬁnite volume corrections arising from these two-pion intermediate states. We also report the ﬁrst lattice calculation of the long-distance contribution to the indirect CP violation parameter, the K. This calculation involves the treatment of a short-distance, ultra-violet divergence that is absent in the calculation of ∆MK, and we will report our techniques for correcting this divergence on the lattice. In this calculation, we used unphysical quark masses on the same ensemble that we used in [1]. Therefore, rather than providing a physical result, this calculation demonstrates the technique for calculating K, and provides an approximate understanding the size of the long-distance contributions. Various new techniques are employed in this work, such as the use of All-Mode-Averaging (AMA), the All-to-All (A2A) propagators and the use of super-jackknife method in analyzing the data.

description: The Fording River, Greenhills and Line Creek Operations are three surface coal mines located adjacent to each other in the Fording and Elk River valleys of southeastern British Columbia. These mines are operated by Elk Valley Coal Corporation, and produce high-quality metallurgical coal. Active programs of reclamation research have been conducted on all three properties. One of the primary objectives of this research has been to evaluate the feasibility of reclamation directly on coal waste, as opposed to reclamation utilizing an overlying capping material. This paper reports on the results, both historic and recent, of this research, and presents conclusions on the success of this practice, as well as future directions for confirming this success.

description: We present observations of the Trumpler 14/Carina I region carried out using the Stratospheric Terahertz Observatory 2 (STO2). The Trumpler 14/Carina I region is in the west part of the Carina Nebula Complex, which is one of the most extreme star-forming regions in the Milky Way. We observed Trumpler 14/Carina I in the 158 $μ$m transition of [C\,{\sc ii}] with a spatial resolution of 48$''$ and a velocity resolution of 0.17 km s$^{-1}$. The observations cover a 0.25$^\circ$ by 0.28$^\circ$ area with central position {\it l} = 297.34$^\circ$, {\it b} = -0.60$^\circ$. The kinematics show that bright [C\,{\sc ii}] structures are spatially and spectrally correlated with the surfaces of CO clouds, tracing the photodissociation region and ionization front of each molecular cloud. Along 7 lines of sight that traverse Tr 14 into the dark ridge to the southwest, we find that the [C\,{\sc ii}] luminosity from the HII region is 3.7 times that from the PDR. In same los we find in the PDRs an average ratio of 1:4.1:5.6 for the mass in atomic gas:dark-CO gas: molecular gas traced by CO. Comparing multiple gas tracers including HI 21cm, [C\,{\sc ii}], CO, and radio recombination lines, we find that the HII regions of the Carina Nebula Complex are well-described as HII regions with one-side freely expanding towards us, consistent with the champagne model of ionized gas evolution. The dispersal of the GMC in this region is dominated by EUV photoevaporation; the dispersal timescale is 20-30 Myr.

description: This dissertation presents new approaches towards the asymmetric allylation of the imino and formyl functionalities by using strained silanes as Lewis acids. Here in the Laboratory of Professor James L. Leighton, chiral homoallylic alcohols and amines are considered privileged products given their important role as building blocks in natural product synthesis. The new approaches reported herein are focused on expanding the scope of imine allylation reactions and gaining full synthetic utility of the corresponding homoallylic amine products by means of economic and user-friendly protocols. In addition, the discovery of a novel catalytic and mild approach to the asymmetric allylation of aldehydes will be the focus of discussion at the end of this works. Chapter 1 will give a brief introduction about general concepts in asymmetric allylation of aldehydes and imines as well as in applications of strained silane Lewis acids in these reactions. Chapter 2 will discuss the development of a novel asymmetric allylation method for N-heteroaryl hydrazones and the N-heteroaryl cleavage from the product to unmask the corresponding free amines. Chapter 3 will carry on these studies into different imine activating groups in search for a more general and user-friendly approach towards both allylation and cleavage protocols. Finally, Chapter 3 will discuss the development of a new methodology in which chiral bismuth (III) complexes can catalyze the asymmetric allylation of aldehydes with achiral strained allylsilanes.

Specific tests include a search for the manifestation of non-metric effects in Lamb-shift transitions of Hydrogenic atoms and in anomalous magnetic moments of massive leptons. We discuss how current experiments already set bounds on the violation of the equivalence principle in this sector and how new (high-precision) measurements of these quantities could provide further information to this end.

The mise en scène of Kingship and Power in Aeschylus’ Seven Against Thebes: Ritual Performativity or Goos, Cledonomancy and Catharsis
Creators: name: Bierl, Anton
Publisher: name: Skenè. Journal of Theatre and Drama Studies
Year: 2019

description: This contribution focuses on Eteocles’ attempts to secure and assert his authority as king and military leader against the female chorus and both the semiotic and self-referential power struggle in the central scene regarding the description of the shields. The extensive pre-dramatic scene of the ecphrastic accumulation of visual signs is interpreted as a symbolic agonistic strife, the theatrical substitute of actual violence. Cledonomantic speech serves as a performative means to convey the oracular anticipation and enigmatic interpretation of the events. Moreover, the paper sheds some light on the mutual reciprocity and circular interaction of fatal entanglements in Thebes and its ruling family. Seen in a cultural perspective of a western Asian healing ritual, the description of the shields can be read as a mise en abyme and mise en scène of the entire play about mutual destruction and the resulting salvation of the polis. Keywords: Aeschylus; Babylonian healing and purification ritual; cledonomancy; choreia; Dionysian palintropic harmony; euphemia; fear and lament; mise en abyme; power struggle with words and bodily regime; Seven against Thebes; supplication.

The algebraic limit of ρ_n contains a finitely generated subgroup F whose 3-dimensional quotient Ω(F)/F has infinitely generated fundamental group, where Ω(F) is the discontinuity domain of F acting on the sphere at infinity. Moreover F is isomorphic to the fundamental group of a closed surface and contains infinitely many conjugacy classes of maximal parabolic subgroups.

description: Fake liquors have caused severe body injuries or even deaths worldwide, rapid detection of such lethal drinks is thus quite necessary. Methanol has been identified as a primary cause of the problem, so methanol monitoring is critical to the detection of fake liquors. The present work provides an effective strategy for rapid detection of different lethal fake liquors. Using gas-phase Fourier transform infrared spectroscopy in a digitally labeled approach, the spectral bands of methanol were extracted by the iterative discrete wavelet transform for classification, which is named as digitally labeled gas-phase Fourier transform infrared spectroscopy. In digitally labeled gas-phase Fourier transform infrared spectroscopy, principal component analysis and least square support vector machine were combined to discriminate problematic samples using the iterative discrete wavelet transform filtered signals. As a result, the method could cleverly extract spectral features of methanol from the alcoholic drinks in the presence of uncontrolled matrix effects. The recognition accuracy was higher than 97.0%, and each measurement was done within 3 min. The results illustrate that the digitally labeled gas-phase Fourier transform infrared spectroscopy method serves well to rapidly discriminate fake liquors as an efficient and promising tool, and could be well extended to detection of any other targeted volatile substance in complicated systems.

description: Over the last two decades, digitization has been drastically shifting the way businesses operate and has provided access to high volume, variety, velocity, and veracity data. Naturally, access to such granular data has opened a wider range of possibilities than previously available. We leverage such data to develop application-driven models in order to evaluate current systems and make better decisions. We explore three application areas. In Chapter 1, we develop models and algorithms to optimize portfolios in daily fantasy sports (DFS). We use opponent-level data to predict behavior of fantasy players via a Dirichlet-multinomial process, and our predictions feed into a novel portfolio construction model. The model is solved via a sequence of binary quadratic programs, motivated by its connection to outperforming stochastic benchmarks, the submodularity of the objective function, and the theory of order statistics. In addition to providing theoretical guarantees, we demonstrate the value of our framework by participating in DFS contests. In Chapter 2, we develop an axiomatic framework for attribution in online advertising, i.e., assessing the contribution of individual ads to product purchase. Leveraging a user-level dataset, we propose a Markovian model to explain user behavior as a function of the ads she is exposed to. We use our model to illustrate limitations of existing heuristics and propose an original framework for attribution, which is motivated by causality and game theory. Furthermore, we establish that our framework coincides with an adjusted ``unique-uniform'' attribution scheme. This scheme is efficiently implementable and can be interpreted as a correction to the commonly used uniform attribution scheme. We supplement our theory with numerics using a real-world large-scale dataset. In Chapter 3, we propose a decision-making algorithm for personalized sequential marketing. As in attribution, using a user-level dataset, we propose a state-based model to capture user behavior as a function of the ad interventions. In contrast with existing approaches that model only the myopic value of an intervention, we also model the long-run value. The objective of the firm is to maximize the probability of purchase and a key challenge it faces is the lack of understanding of the state-specific effects of interventions. We propose a model-free learning algorithm for decision-making in such a setting. Our algorithm inherits the simplicity of Thompson sampling for a multi-armed bandit setting and we prove its asymptotic optimality. We supplement our theory with numerics on an email marketing dataset.

Decision making

description: In the advent of Big Data and Machine Learning, there is a demand for improved decision making in unknown, complex environments. Decision making under uncertainty is a common principle underlying many important decisions made by individuals, businesses, and society as a whole. These problems are typically modeled as multi-armed bandits (MAB), or, more generally, reinforcement learning (RL). In the MAB problem, an agent is faced with many options or arms, each with its own unknown reward distribution, and must determine the sequence of arms to pull, taking into account history of rewards of past pulls. The agent must balance exploration (pulling less-explored arms to learn the model), with exploitation (pulling the current reward maximizing arm so far). RL is a generalized, more complex extension of the MAB problem in which the current state, in addition to the arm or action, impacts the obtained reward. In this thesis, we focus on designing new algorithms to better address RL problems. In particular, we design an algorithm inspired by Thompson sampling for finite communicating MDPs and an algorithm inspired by stochastic convex optimization for some fundamental problems in operations management, including a problem in inventory control. We develop intuitive algorithms and prove theoretical bounds on their regret; in doing so, we derive some theoretically interesting analytical results that may be of independent interest.

description: Efficient point cloud compression is fundamental to enable the deployment of virtual and mixed reality applications, since the number of points to code can range in the order of millions. In this paper, we present a novel data-driven geometry compression method for static point clouds based on learned convolutional transforms and uniform quantization. We perform joint optimization of both rate and distortion using a trade-off parameter. In addition, we cast the decoding process as a binary classification of the point cloud occupancy map. Our method outperforms the MPEG reference solution in terms of rate-distortion on the Microsoft Voxelized Upper Bodies dataset with 51.5% BDBR savings on average. Moreover, while octree-based methods face exponential diminution of the number of points at low bitrates, our method still produces high resolution outputs even at low bitrates.

Some examples from Boliden's programme for mine sites reclamation
Creators: name: Lindvall, Manfred
Publisher: name: The University of British Columbia
Year: 2009

description: Since 1924, Boliden has been operating nearly 50 mines and 13 concentrators in Sweden and an additional 6 mines in other countries. In the last 10-15 years, substantial effort has been put into reclamation of closed sites. As a general principle, site specific solutions have been developed, aiming at walk away solutions. The techniques used are in most cases combinations of flooding and dry cover, but also innovations such as groundwater saturation have been introduced. Various methods to enhance the integrity of the reclaimed area by establishing sustainable vegetation have been applied. A significant step forward has been taken by using various waste fractions from the municipal society. Without exception, the results have surpassed the forecast. New ecosystems are developing, with a wide variety of species on reclaimed areas and fish populations are establishing in flooded tailings ponds. The challenge for the future will be to develop principles and methods for transferring reclaimed areas back to society. To accomplish such a process, innovative solutions for new land uses will be required. This calls for an approach that reaches beyond the strictly technical considerations. This paper will give a brief review of the principles and the programme for mine site reclamation and the technical considerations involved, focusing on the conditions in Sweden, where the majority of the sites in the reference list are found.
“Breath of Kings”: Political and Theatrical Power in Richard II
Creators: name: Schalkwyk, David

description: This essay challenges the way in which Richard II has been perceived and portrayed in recent films and theatrical adaptations and in literary criticism since Coleridge. It bases its research on experimental productions by Anərkē Shakespeare, using original practice techniques without a director, relying solely on the text rather than external conceptual impositions. Scrutinising Richard’s language as both an embodiment of performance, and embodied in performance, obviates received caricatures of Richard as weak, effeminate, gay, and capricious. It uses J.L. Austin’s analysis of perlocutionary and illocutionary performatives to show the degree to which Richard’s illocutionary fragility, as he loses political power at a local level, develops a perlocutionary strength in which he demonstrates unexpected performative capacities. It argues that political power and theatrical power in the play are inversely proportional to each other. Consequently, as Richard gains theatrical power he achieves a far greater political force beyond the confines of the play. In the only soliloquy, Richard appeals directly to a universal need to accept our common state of nothingness: “whate’er I be, / Nor I nor any man that but man is / With nothing shall be pleased till he be eased / With being nothing”. Revealing only then that we can be something.

Curses in Aeschylus’ Seven Against Thebes and in Shakespeare’s Richard Plays

description: Despite differences in theatrical convention and cultural context, Aeschylus’ Seven Against Thebes and Shakespeare’s Richard II and Richard III share important similarities: each occurs in a sequence of plays and features a ruler who, initially sure of himself, suffers a crashing downfall and death. Variously represented, curses, that is, callings for supernatural punishment upon people, appear centrally in these plays and structure their unfolding actions. Aeschylus’ play presents the fulfillment of Oedipus’ curse on his sons, Eteocles and Polyneices. Eteocles’ confrontation with the curse both enables its fulfillment and defines his tragedy. Contrarily, characters curse each other in Richard II, but they do so ineffectually. In this play God’s curse in Genesis structures and defines the action. Margaret’s curses appear efficacious in Richard III but actually just serve to indicate the potent reality of divine retribution. In Shakespeare’s plays confrontation with curses enable their fulfillment and constitutes the rulers’ tragedies. Notice of the agency and operation of curses in these three plays reveals the different theologies, dramas, and tragedies they present.

Hierarchical Mean-Field Theories in Quantum Statistical Mechanics

description: We present a theoretical framework and a calculational scheme to study the coexistence and competition of thermodynamic phases in quantum statistical mechanics. The crux of the method is the realization that the microscopic Hamiltonian, modeling the system, can always be written in a hierarchical operator language that unveils all symmetry generators of the problem and, thus, possible thermodynamic phases. In general one cannot compute the thermodynamic or zero-temperature properties exactly and an approximate scheme named ``hierarchical mean-field approach'' is introduced. This approach treats all possible competing orders on an equal footing. We illustrate the methodology by determining the phase diagram and quantum critical point of a bosonic lattice model which displays coexistence and competition between antiferromagnetism and superfluidity.

description: In recent decades, the multiple pressures determined by the extremely complex context in which organizations have found themselves operating, have imposed incessant changes in management and strategic policies, in order to face and, therefore, identify new solutions to possible problems. The world of production and, in particular, that of fashion is called upon to assume precise moral responsibilities based on socially shared ethical principles, capable of creating, through wise and far-sighted strategies, a sustainable value for all the actors of the ‘web of life’. The purpose of this paper is to highlight how the involvement of organizations operating in the fashion industry is necessary to “build” lasting sustainability, as it is capable of integrating growth with competitiveness, environmental protection and social development. This is due to the extraordinary synergies that can arise from the structured adoption of paths marked by sustainability, the inclusion of diversity and the promotion of local development-oriented dynamics.

description: Urban congestion has become an increasingly serious issue in developing countries in recent decades. Nearly a century years ago, many big cities in developed countries suffered substantial urban congestions and brought about lots of approaches to deal with that. New towns have been constructed near big cities to deal with urban congestions since their earliest emergence in developed countries like the UK, France, Japan and so on. London New Towns has accumulated plenty of valuable experience and lessons to learn from. This thesis researches whether Xiongan New Area, a 100 km planned district from Beijing, is a good policy to deal with the urban congestion of Beijing based on the lessons learned from previous new towns. Suggestions about new town development are given based on the review of new towns of London, Paris and other Asian countries. The research assesses the Xiongan New Area Planning Outline comprehensively in five dimensions. It was found that the Planning Outline was generally well made and set out a blueprint for future development. It avoids many mistakes made by previous new town constructions and puts forward many creative and progressive ideas to build a greener and better place. However, there are also some problems in terms of community creation and public participation. Based on the strategy change of London in the 21st century, it is also found that denser development in the central areas has become the main trend of global big cities. To better deal with the urban congestion of Beijing, this strategy should be pushed forward along with the development of the New Area to control the unordered growth in the central city and rearrange regional resources more efficiently.
