description: We describe the effects of geometric torsion on the coherent motion of electrons along a thin twisted quantum ring. The geometric torsion inherent in the quantum ring triggers a quantum phase shift in the electrons' eigenstates, thereby resulting in a torsion-induced persistent current that flows along the twisted quantum ring. The physical conditions required for detecting the current flow are discussed.

description: Long-wavelength spin fluctuations prohibit antiferromagnetic long-range order at finite temperature in two dimensions. Nevertheless, the correlation length starts to grow rapidly at a crossover temperature, leading to critical slowing down and to a renormalized-classical regime over a wide range of temperature, between a fraction of the mean-field transition temperature and the zero-temperature ordered state. This leads to a single-particle pseudogap of the kind observed in electron-doped cuprates. Very few theoretical methods can claim an accurate description of this regime. The challenge is that in this regime Fermi-liquid quasiparticles are already destroyed and new quasiparticles of the ordered state are not fully formed yet. Here, we study this problem for the two-dimensional Hubbard model by first generalizing the two-particle self-consistent approach. Using a special algorithm, spin fluctuations are treated in the thermodynamic limit even for large correlation lengths. The effects of Kanamori-Brückner screening, of classical and of quantum fluctuations are taken into account. Results are presented at half-filling for the one-band Hubbard model with nearest-neighbor hopping. They agree well with available benchmark diagrammatic quantum Monte Carlo at high temperature where the pseudogap opens up. In addition to temperature-dependent spectral properties, we find quantum corrections to the zero-temperature renormalized mean-field antiferromagnetic gap. Finally, analytic continuation of the Matsubara results for spectral functions show that the pseudogap opens up at significantly higher temperature than was previously identified based on the Matsubara data only.

description: In microgravity experiments, we quantified the net charge on systems of two identical, 434 \textmu m diameter glass spheres before and after a collision. We find that charge conservation is significantly violated. Independent of the sign of the total charge, the systems regularly lose some of their net charges, that is, they slightly discharge. This implies that positive as well as negative charge carriers become entrained into the surrounding atmosphere during a collision.
Persistent entanglement due to helicity conservation in excitable media

description: This work addresses the topic of knotted stable structures in excitable media. These structures appear in a wide variety of situations, such as cardiac fibrillation, chemical reactions, etc. Entangled curves have been found in numerical computations of the equations that describe excitable media. They present an unusual stability. An explanation for this behaviour has been an open question. In the present work we introduce for the first time the meaning of the helicity in an excitable media as a new tool to study the stability of these systems. The helicity is related to the total entanglement of the system. We have studied how the helicity is conserved or lost through the walls of the medium and shown that these behaviours are dominated by the boundary conditions, so the distortion of these conditions could lead to the disappearance of the structures.

description: Revisiting Einstein's gravitational theory, we build a five-dimensional braneworld. Within this framework, one announces the appearance of symmetric and asymmetric domain walls. Furthermore, it examines the emergent four-dimensional gravity from a theory with non-canonical dynamics. Exploring the physical and mathematical aspects, e.g., brane's energy density and the Kaluza-Klein (KK) spectrum, one verifies that brane splitting is absent in the canonical and non-canonical theories. Additionally, we note the localization of the four-dimensional fluctuation projection on the 3-branes, which ensures the theory's stability. Thereby, one can conclude that the behavior of gravitational perturbations of the domain wall maintains a profile similar to a stable and non-localizable tower of massive modes. In contrast, within the brane core, the matter sector generates new barriers and potential wells, resulting in massive modes with approximately symmetric amplitudes. However, the non-canonical dynamics generate massive modes with asymmetric amplitudes far from the 3-brane.

description: With the recent burst of 2D and 3D data, cross-modal retrieval has attracted increasing attention recently. However, manual labeling by non-experts will inevitably introduce corrupted annotations given ambiguous 2D/3D content. Though previous works have addressed this issue by designing a naive division strategy with hand-crafted thresholds, their performance generally exhibits great sensitivity to the threshold value. Besides, they fail to fully utilize the valuable supervisory signals within each divided subset. To tackle this problem, we propose a Divide-and-conquer 2D-3D cross-modal Alignment and Correction framework (DAC), which comprises Multimodal Dynamic Division (MDD) and Adaptive Alignment and Correction (AAC). Specifically, the former performs accurate sample division by adaptive credibility modeling for each sample based on the compensation information within multimodal loss distribution. Then in AAC, samples in distinct subsets are exploited with different alignment strategies to fully enhance the semantic compactness and meanwhile alleviate over-fitting to noisy labels, where a self-correction strategy is introduced to improve the quality of representation. Moreover. To evaluate the effectiveness in real-world scenarios, we introduce a challenging noisy benchmark, namely Objaverse-N200, which comprises 200k-level samples annotated with 1156 realistic noisy labels. Extensive experiments on both traditional and the newly proposed benchmarks demonstrate the generality and superiority of our DAC, where DAC outperforms state-of-the-art models by a large margin. (i.e., with +5.9% gain on ModelNet40 and +5.8% on Objaverse-N200).

description: The continuous emergence of resistance to the available drugs poses major constraints in the development of effective therapeutics against Malaria. The Malaria drug resistance has been attributed to be the manifestation of numerous factors. For example, mutations in the parasite transporter protein acetyl-CoA transporter (Pfact) can remarkably affect its uptake affinity for a drug molecule against malaria, and hence enhance its susceptibility to resistance. To identify major contributors to its loss of functionality, we have thoroughly scrutinized eight such recently reported resistant mutants, via in-silico tools in terms of alterations in different properties. We performed molecular dynamics simulations of the selected Pfact mutants to gain deeper insights into the structural perturbation and dynamicity. Comparison of residue interaction network map of mutants with that of Wild type (WT) protein suggests structural changes as a result of the mutation(s) that translate into the weakening of intra-protein interactions, especially around the drug binding pocket. This, in turn, diminishes the affinity of drug molecules towards the binding site, which was validated by docking analysis. Finally, collating all the observations, we have delineated R108K mutant to deviate the most from WT protein, which, intriguingly suggests that replacing an amino acid with another of similar nature can even translate into greater functional effects as those with dissimilar substitutions.

Urban growth management : the development of a program for the Edmonton area
Creators: name: Scott, William Guy
Publisher: name: University of British Columbia
Year: 2010

description: Urban growth management is a topic of relatively new but increasing interest. Throughout North America, numerous communities are attempting to modify or manage their growth patterns. This thesis has attempted to draw together the reasons for this new concern for growth management, the techniques used to accomplish it and the considerations inherent in the actual development of a management program. In order that a real world perspective be achieved, the Edmonton area of Alberta was considered. Through data obtained from the Edmonton Regional Planning Commission as well as from a number of other governmental agencies and through the author's employment with the Planning Commission, an insight into the current growth patterns and problems of the area was attained. Following the introduction, a discussion of the new concern for growth management is presented in Chapter II. Three general areas of concern are described: social, environmental and economic. Chapter III enumerates and briefly reviews various growth management techniques as they are applied in North America. As the legality of any management technique is crucial to its success, Chapter IV discusses the legal basis for the various growth management techniques in the Alberta setting. A detailed explanation of the use of the Subdivision and Transfer Regulations of Alberta is used to exemplify the legal adequacy of some growth management techniques. With this background data, the development of a growth management program for the Edmonton area was initiated. Chapter V summarizes the current population and economic growth of the area as well as the views of the three levels of government and those of the general populace concerning growth. Finally, Chapter VI brings together the work from the preceeding chapters to develop a growth management program for the decentralization and reallocation of the population and economic growth of the area.

description: We study in this work the two-body hadronic charmed meson decays, including both the PP and VP modes. The latest experimental data are first analyzed in the diagrammatic approach. The magnitudes and strong phases of the flavor amplitudes are extracted from the Cabibbo-favored (CF) decay modes using $χ^2$ minimization. The best-fitted values are then used to predict the branching fractions of the singly-Cabibbo-suppressed (SCS) and doubly-Cabibbo-suppressed decay modes in the flavor SU(3) symmetry limit. We observe significant SU(3) breaking effects in some of SCS channels. In the case of VP modes, we point out that the $A_P$ and $A_V$ amplitudes cannot be completely determined based on currently available data. We conjecture that the quoted experimental results for both $D_s^+\to\bar K^0K^{*+}$ and $D_s^+\to ρ^+η'$ are overestimated. We compare the sizes of color-allowed and color-suppressed tree amplitudes extracted from the diagrammatical approach with the effective parameters $a_1$ and $a_2$ defined in the factorization approach. The ratio $|a_2/a_1|$ is more or less universal among the $D \to {\bar K} π$, ${\bar K}^* π$ and ${\bar K} ρ$ modes. This feature allows us to discriminate between different solutions of topological amplitudes. For the long-standing puzzle about the ratio $Γ(D^0\to K^+K^-)/Γ(D^0\toπ^+π^-)$, we argue that, in addition to the SU(3) breaking effect in the spectator amplitudes, the long-distance resonant contribution through the nearby resonance $f_0(1710)$ can naturally explain why $D^0$ decays more copiously to $K^+ K^-$ than $π^+ π^-$ through the $W$-exchange topology.

description: Explicit models representing the response variables as functions of the control variables are standard in virtually all scientific fields. For these models there is a vast literature on the optimal design of experiments to provide good estimates of the parameters with the use of minimal resources. Contrarily, the optimal design of experiments for implicit models is more complex and has not been systematically addressed. Nevertheless, there are practical examples where the models relating the response variables, the parameters and the factors are implicit or hardly convertible into an explicit form. We propose a general formulation for developing the theory of the optimal design of experiments (ODoE) for implicit algebraic models to specifically find continuous local designs. The treatment relies on converting the ODoE problem into an optimization problem of the Nonlinear Programming class which includes the construction of the parameter sensitivities and the Cholesky decomposition of the Fisher Information Matrix. The Nonlinear Programming problem generated has multiple local optima, and we use global solvers, combined with an equivalence theorem from the theory of ODoE, to ensure the global optimality of our continuous optimal designs. We consider D– and A–optimality criteria and apply the approach to five examples of practical interest in chemistry and thermodynamics.

description: Histone deacetylases (HDACs) are a widely popular class of epigenetic regulators, second only in importance to DNA methyltransferases. They are responsible for deacetylating the lysine residues of a wide range of proteins, both nuclear and cytoplasmic. Therefore, deregulated HDAC activity is implicated in disruption of important biological functions leading to cancerous, neuropathological, infectious and inflammatory diseased states. The current therapeutic strategies aimed at combating HDAC related pathologies consist of pan HDAC inhibitors that target multiple HDAC isoforms. Many side-effects of such therapeutics have been reported due to off-target effects. Hence, efforts need to be focused towards developing therapeutics targeting single isoforms. This work aims at recognizing structural features, both of receptors and inhibitors, that would help achieve selective inhibition of HDAC isoforms. Protein alignment studies have been carried out to define the receptor structure differences that can be exploited for this purpose. Binding modes of highly isoform selective inhibitors have been established through molecular docking studies to characterize the receptor-ligand interactions responsible for selective inhibition. This information is represented with the help of pharmacophore models.

description: Quantum computing algorithms have been shown to produce performant quantum kernels for machine-learning classification problems. Here, we examine the performance of quantum kernels for regression problems of practical interest. For an unbiased benchmarking of quantum kernels, it is necessary to construct the most optimal functional form of the classical kernels and the most optimal quantum kernels for each given data set. We develop an algorithm that uses an analog of the Bayesian information criterion to optimize the sequence of quantum gates used to estimate quantum kernels for Gaussian process models. The algorithm increases the complexity of the quantum circuits incrementally, while improving the performance of the resulting kernels, and is shown to yield much higher model accuracy with fewer quantum gates than a fixed quantum circuit ansatz. We demonstrate that quantum kernels thus obtained can be used to build accurate models of global potential energy surfaces (PES) for polyatomic molecules. The average interpolation error of the six-dimensional PES obtained with a random distribution of 2000 energy points is 16 cm$^{-1}$ for H$_3$O$^+$, 15 cm$^{-1}$ for H$_2$CO and 88 cm$^{-1}$ for HNO$_2$. We show that a compositional optimization of classical kernels for Gaussian process regression converges to the same errors. This indicates that quantum kernels can achieve the same, though not better, expressivity as classical kernels for regression problems.

description: La ripresa degli studi sulla manualistica del recupero ha contribuito, attraverso una lettura tecnica vista in prospettiva storica, a diffondere sensibilità conoscitiva e consapevolezza del patrimonio premoderno. Tuttavia l’esigenza di superare il tracciato delineato dall’uso dei manuali di recupero – da molti intesi, semplicisticamente, come cataloghi per soluzioni architettoniche di ripristino e ricostruzione – ha reso indispensabile una riflessione sul reale bisogno di questi strumenti e sulle loro ripercussioni operative. Se i manuali, spesso, esprimono una visione statica e totalizzante dell’edilizia storica, l’atlante dichiara una concezione dinamica e “sempre aperta”, in cui ogni elemento rilevato è caso a sé. L’atlante fa, quindi, riferimento ad una concezione “geografica” in cui la catalogazione non è esaustiva e dogmatica ma, contrariamente, dà luogo ad un repertorio di casi criticamente analizzati nell’ottica della conoscenza e della conservazione. 
L’obiettivo della ricerca non è consistito, pertanto, nel descrivere la totalità dei caratteri costruttivi e delle loro combinazioni, ma nell’individuare casi singoli che sono letti ed interpretati all’interno del loro contesto storico-costruttivo e che valgono quale monito per un’azione progettuale consapevole, orientata al minimo intervento e alla compatibilità fisico-meccanica, figurativa e filologica. 
Nello specifico la ricerca, collocata in un riferimento temporale compreso tra il XIII e il XIX secolo, ha approfondito i seguenti caratteri: solai lignei, appartato decorativo in cotto e portali. 
Attraverso un approccio interdisciplinare lo studio si è proposto di contribuire alla costituzione di una metodologia di ricerca sulle tecniche costruttive storiche, ravvisando nel momento conoscitivo la prima fase del progetto di conservazione. È indiscusso, infatti, il solido legame che esiste tra conoscenza, progetto ed operatività. Solo attraverso la consapevolezza storica e architettonica del manufatto è possibile individuare scelte conservative criticamente vagliate ed operare in funzione della specificità del  caso in esame e delle sue reali necessità.
description: The research aims to identify a survey of Bolognese wooden floors, terracotta friezes and portals. Every element that characterizes the Bolognese historical architectural organism has been studied from an historical-critical and historical-technical point of view thanks to the prolific relationship between indirect sources and direct ones, in order to reach the full understanding of each architectural components. This awareness is the first step for a ‘conscious’ planning strategy of conservation which is consistently valid from a methodological point of view but not standardized in technical applications.

description: A crystallographic and magnetic phase diagram of SmFeAsO1-xFx is determined as a function of x in terms of temperature based on electrical transport and magnetization, synchrotron powder x-ray diffraction, 57Fe Mossbauer spectra (MS), and 149Sm nuclear resonant forward scattering (NRFS) measurements. MS revealed that the magnetic moments of Fe were aligned antiferromagnetically at ~144 K (TN(Fe)). The magnetic moment of Fe (MFe) is estimated to be 0.34 myuB/Fe at 4.2 K for undoped SmFeAsO; MFe is quenched in superconducting F-doped SmFeAsO. 149Sm NRFS spectra revealed that the magnetic moments of Sm start to order antiferromagnetically at 5.6 K (undoped) and 4.4 K (TN(Sm)) (x = 0.069). Results clearly indicate that the antiferromagnetic Sm sublattice coexists with the superconducting phase in SmFeAsO1-xFx below TN(Sm), while antiferromagnetic Fe sublattice does not coexist with the superconducting phase.

description: This article proposes a new approach to modeling high-dimensional time series by treating a p-dimensional time series as a nonsingular linear transformation of certain common factors and idiosyncratic components. Unlike the approximate factor models, we assume that the factors capture all the nontrivial dynamics of the data, but the cross-sectional dependence may be explained by both the factors and the idiosyncratic components. Under the proposed model, (a) the factor process is dynamically dependent and the idiosyncratic component is a white noise process, and (b) the largest eigenvalues of the covariance matrix of the idiosyncratic components may diverge to infinity as the dimension p increases. We propose a white noise testing procedure for high-dimensional time series to determine the number of white noise components and, hence, the number of common factors, and introduce a projected principal component analysis (PCA) to eliminate the diverging effect of the idiosyncratic noises. Asymptotic properties of the proposed method are established for both fixed p and diverging p as the sample size n increases to infinity. We use both simulated data and real examples to assess the performance of the proposed method. We also compare our method with two commonly used methods in the literature concerning the forecastability of the extracted factors and find that the proposed approach not only provides interpretable results, but also performs well in out-of-sample forecasting.

description: By assuming a phenomenological form for the ratio of the DE and DM densities $ρ_X\propto ρ_{m} a^ξ$ (Dalal et al.2001), we discuss the cosmic coincidence problem in light of current observational data. $ξ$ is a key parameter to denote the severity of the coincidence problem. In this scenario, $ξ=3$ and $ξ=0$ correspond to $Λ$CDM and the self-similar solution without coincidence problem, respectively. Hence, any solution with a scaling parameter $0 0.73$, within the framework of this model, we can conclude that the interaction between DE and DM is necessary.

description: This study examines the formulation of a singularity theorem for timelike curves including torsion, and establishes the foundational framework necessary for its derivation. We begin by deriving the relative acceleration for an arbitrary congruence of timelike curves. The resulting ``deviation equation'' offers an alternative pathway to the well-known Raychaudhuri equation with torsion. Conjugate points are then introduced and analyzed in relation to the behavior of the scalar expansion. Together with the sensible requirement of hypersurface orthogonality, the Raychaudhuri equation is examined for several specific cases of torsion that are prominent in the literature. Our findings indicate that a totally antisymmetric torsion tensor does not influence the behavior of the congruence of timelike curves. Finally, we formulate a singularity theorem for timelike curves and highlight the critical requirement of non-autoparallel curves.

description: In an empirical Bayes analysis, we use data from repeated sampling to imitate inferences made by an oracle Bayesian with extensive knowledge of the data-generating distribution. Existing results provide a comprehensive characterization of when and why empirical Bayes point estimates accurately recover oracle Bayes behavior. In this paper, we develop flexible and practical confidence intervals that provide asymptotic frequentist coverage of empirical Bayes estimands, such as the posterior mean or the local false sign rate. The coverage statements hold even when the estimands are only partially identified or when empirical Bayes point estimates converge very slowly.

description: The binding mode of cationic porphyrin (trans-BMPyP) with poly[d(G-C)2] and poly[d(A-T)2] was examined according to the site of the periphery cationic methyl pyridine ion of the cationic porphyrin (o-, m-, p-) as well as the possibility of a B-Z transition depending on the binding modes by measuring the absorption spectrum and circular dichroism (CD). The negative band found in the soret region showed the intercalation mode of m- and p-trans-BMPyP-poly[d(G-C)2] to the DNA base pairs, but no B-Z transition was induced. On the other hand, the distinctive bisignate band found in the soret region of the CD spectrum for m- and p-trans-BMPyP-poly[d(A-T)2] suggests that m- and p-trans-BMPyP have an effective extensive stacking-based binding mode along with the skeleton of poly[d(A-T)2], wherein the B-Z transition was induced through extensive stacking. The difference in binding mode was attributed to the difference in the molecular structure depending on the site of the periphery cationic methyl pyridine ion in the cationic porphyrin. In other words, o-trans-BMPyP is nonplanar because of the steric hindrance of the cationic methyl pyridine ion at the o-site. In contrast, m- and p-trans-BMPyP are planar, but not all porphyrins with a planar structure undergo the B-Z transition. In conclusion, a B-Z transition is induced if the structure of a porphyrin is planar and the binding mode allows the porphyrins to be stacked effectively along the DNA skeleton, not in a binding mode where the porphyrin is intercalated to the DNA.
title: Effective robotic control through anticipating synchronisation
Creators: name: Eberle, Henry
Publisher: name: University of Reading

description: This thesis describes the development of a robotic control scheme with a novel ‘parallel’ design that combines direct feedback control with the simultaneous output of a dynamical forward model. Unlike existing predictive control schemes with a serial ‘sense-calculate-move’ structure where the model fully determines the robot’s behaviour, the parallel controller can adapt to overcome any feedback delay the system experiences without updating its parameters. This is thanks to replicating the key properties of anticipating synchronisation (AS), where a slave system (the robot) anticipates a similar master (a moving target) via delayed self-feedback. Since the robot and target possess very diﬀerent dynamics, the output of the forward model is used to impose a suitable dynamical behaviour on the robot, while the direct feedback term simultaneously drives the robot itself to anticipate the target. This means that the forward model does not have to be related to the robot’s true dynamics so long as it represents a suitable AS slave system, and that any feedback delay will inevitably be opposed by a proportional degree of anticipation. The result is a highly robust and adaptable predictive controller that can be applied to a robot without requiring precise knowledge of its dynamics.

description: One of the most striking results is the large elliptic flow ($v_2$) at RHIC. Detailed mass and transverse momentum dependence of elliptic flow are well described by ideal hydrodynamic calculations for $p_{\mathrm{T}} < $ 1 GeV/c, and by parton coalescence/recombination picture for $p_{\mathrm{T}} = 2 - 6$ GeV/c. The systematic error on $v_2$ is dominated by so-called "non-flow effects", which is the correlation not originated from reaction plane. It is crucial to understand and reduce the systematic error from non-flow effects in order to understand the underlying collision dynamics. In this paper, we present the centrality dependence of $v_2$ with respect to the first harmonic event plane at ZDC-SMD ($v_2$\{ZDC-SMD\}) in Au + Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. Large rapidity gap ($|Δη| > 6$) between midrapidity and the ZDC could enable us to minimize possible non-flow contributions. We compare the results of $v_2$\{ZDC-SMD\} with $v_2$\{BBC\}, which is measured by event plane determined at $|η| = 3.1 - 3.9$. Possible non-flow contributions in those results will be discussed.

description: Polar stratospheric clouds (PSCs) are important for the chemical activation of chlorine compounds and subsequent ozone depletion. However, how solid PSCs form is still subject to controversial discussion. Recently, the octahydrate of sulfuric acid (H2SO48H2O) has been proposed as a solid phase for PSC particles. In our experiment single H2SO4/H2O aerosols levitated in an electrodynamic balance are cooled to 158 K along the ice-liquid equilibrium line. This coexistence curve has been measured for the first time in the temperature interval between 200 K and 158 K. Three independent methods are used for measuring the H2SO4 concentration of the aerosol. No phase transition is observed over a time period of 24 hours and longer at these or higher temperatures. There is no indication for the occurrence of the octahydrate in our experiments. Since the product of experimental volume and suspension time is equal to that of stratospheric droplets over an entire winter, the homogeneous formation of the octahydrate at quasi-thermodynamic equilibrium can be practically excluded.

description: Phytoestrogens are dietary estrogens having similar structure as of estrogen. Some of these phytoestrogens are androgen receptor (AR) antagonists and exhibit preventive role in the prostate cancer. However, in androgen-independent prostate cancer (AIPC) the ARs were mutated (T877A, W741L, F876L, etc.) and these mutant ARs convert the antagonist to agonist. Our aim in this study is to find phytoestrogens that could function as an antagonist with wild and mutant ARs. The phytoestrogens were analyzed for binding affinity with wild and mutant ARs in agonist and antagonist conformations. The point mutations were carried out using Chimera. The antagonist AR conformation was modeled using Modeller. We hypothesize that the compounds having binding affinity with agonist AR conformation could not function as a full or pure antagonist. Most of the phytoestrogens have binding affinity with agonist AR conformation contradicting previous results. For example, genistein which is a widely studied isoflavone has known AR antagonist property. However, in our study, it had good binding affinity with agonist AR conformation. Hence, to confirm our hypothesis, we tested genistein in LNCaP (T877A mutant AR) cells by qPCR studies. The genistein functioned as an antagonist only in the presence of an androgen indicting a partial agonist type of activity. The in-vitro results supported our docking hypothesis. We applied this principle and found syringaresinol could function as an antagonist with wild and mutated ARs. Further, we carried out molecular dynamics for the hit molecule to confirm its antagonist binding mode with mutant AR. Communicated by Ramaswamy H. Sarma
