description: We develop a theory for the susceptible-infected-susceptible (SIS) epidemic model on networks that incorporate both network structure and dynamic correlations. This theory can account for the multistage onset of the epidemic phase in scale-free networks. This phenomenon is characterized by multiple peaks in the susceptibility as a function of the infection rate. It can be explained by that, even under the global epidemic threshold, a hub can sustain the epidemics for an extended period. Moreover, our approach improves theoretical calculations of prevalence close to the threshold in heterogeneous networks and also can predict the average risk of infection for neighbors of nodes with different degree and state on uncorrelated static networks.

description: In the context of the search for environment-respectful, lead- and bismuth- free chemical compounds for devices such as actuators, SnTiO3 (ST) is investigated from first principles within DFT. Full geometry optimization provides a stable tetragonal structure relative to cubic one. From the equation of state the equilibrium volume of SnTiO3 is found smaller than ferroelectric PbTiO3 (PT) in agreement with a smaller Sn2+ radius. While ionic displacements exhibit similar trends between ST and PT a larger tetragonality (c/a ratio) for ST results in a larger polarization, PST = 1.1 C.m2. The analysis of the electronic band structure detailing the Sn-O and Ti-O interactions points to a differentiated chemical bonding and a reinforcement of the covalent bonding with respect to Pb homologue.

description: In an electronic system with various interactions intertwined, revealing the origin of its many-body ground state is challenging and a direct experimental way to verify the correlated nature of an insulator has been lacking. Here we demonstrate a way to unambiguously distinguish a paradigmatic correlated insulator, a Mott insulator, from a trivial band insulator based on their distinct chemical behavior for a surface adsorbate using 1T-TaS2, which has been debated between a spin-frustrated Mott insulator or a spin-singlet trivial insulator. We start from the observation of different sizes of spectral gaps on different surface terminations and show that potassium adatoms on these two surface layers behave in totally different ways. This can be straightforwardly understood from distinct properties of a Mott and a band insulators due to the fundamental difference of a half and a full-filled orbital involved respectively. This work not only solves an outstanding problem in this particularly interesting material but also provides a simple touchstone to identify the correlated ground state of electrons experimentally.

description: Gravitational waves (GWs) have opened a new window on fundamental physics in a number of important ways. The next generation of GW detectors may reveal more information about the polarization structure of GWs. Additionally, there is growing interest in theories of gravity beyond GR. One such theory which remains viable within the context of recent measurements of the speed of propagation of GWs is the teleparallel analogue of Horndeski gravity. In this work, we explore the polarization structure of this newly proposed formulation of Horndeski theory. In curvature-based gravity, Horndeski theory is almost synonymous with extensions to GR since it spans a large portion of these possible extensions. We perform this calculation by taking perturbations about a Minkowski background and consider which mode propagates. The result is that the polarization structure depends on the choice of model parameters in the teleparallel Horndeski Lagrangian with a maximum of seven propagating degrees of freedom. While the curvature-based Horndeski results follows as a particular limit within this setup, we find a much richer structure of both massive and massless cases which produce scalar--vector--tensor propagating degrees of freedom. We also find that the GW polarization that emerges from the teleparallel analogue of Horndeski gravity results in analogous massive and massless modes which take on at most four polarizations in the massless sector and two scalar ones in the massive sector. In none of the cases do we find vector polarizations.

description: We present dynamical mean field theory (DMFT) results for the local spectral densities of the one- and two-particle response functions for the infinite dimensional Hubbard model in a magnetic field. We look at the different regimes corresponding to half-filling, near half-filling and well away from half-filling, for intermediate and strong values of the local interaction $U$. The low energy results are analyzed in terms of quasiparticles with field dependent parameters. The renormalized parameters are determined by two different methods, both based on numerical renormalization group (NRG) calculations, and we find good agreement. Away from half-filling the quasiparticle weights, $z_σ(H)$, differ according to the spin type $σ=\uparrow$ or $σ=\downarrow$. Using the renormalized parameters, we show that DMFT-NRG results for the local longitudinal and transverse dynamic spin susceptibilities in an arbitrary field can be understood in terms of repeated scattering of these quasiparticles. We also check Luttinger's theorem for the Hubbard model and find it to be satisfied in all parameter regimes and for all values of the magnetic field.

The researcher looked at how children utilized the forum and searched for common themes. She found that very little interpersonal interaction occurred on the site, but that the users appeared engaged with both the site and the topic of environmentalism. The children's understandings of the environmental problems faced by the world were generally simplistic and did not necessarily represent the most pressing issues identified by environmentalists.

We determine the limit of the quantum fidelity between the true quantum trajectory and the {estimated one}. Under a purification assumption we show that this limit equals to one meaning that quantum filters are stable. In the general case, under an identifiability and a spectral assumption we show that the limit of the Cesaro mean of the estimated trajectory is the same as the true one.

description: Water supply system from source, treatment, storage and distribution for use has come under pressure from increased population and urbanisation. In search of solutions, the governance theme emerged as a path to sustainable water supply and management and has been in fore of research since 2003. Accompanying this conceptual shift has been moves towards frameworks for managing water supply with some focusing on consumer behaviours such as willingness to pay water bills. However, behavioural studies in the water supply have focused on utilities, whereas the evidence indicates that water supply in developing countries, especially sub-Saharan Africa is dominated by non-utility water supply systems (NUWSS).

The emerging dominance of NUWSS as the primary source of water supply motivates a re-thinking of existing management protocols as well as assessing determinants of regulatory compliance in NUWSS. The theory of planned behaviour (TPB) is used to target determinants to regulatory compliance across the groups of indicators identified for the regulation of water supply systems. Specifically, TPB was used to initiate this re-thinking process in the management of water supply in NUWSS by examining the influence of behavioural, demographic, and social factors on regulatory compliance by households using NUWSS in Uyo, Nigeria.
The variables in TPB was used to structure the data collection instruments, while indicators enumerated by International Water Association was adapted to formulate the questions posed to respondents. The research used a mixed-method study design with samples drawn from residential areas in Uyo, Nigeria. A total of five hundred and fifty households using NUWSS were surveyed, twenty-nine households interviewed, documents were analysed, and other stakeholders in water supply consulted concerning regulation in NUWSS. Structural equation modelling (SEM) and thematic analysis were used to analyse the data.
The findings indicate that regulatory compliance in NUWSS are significantly and directly influenced by subjective norms and self-efficacy. Also, the analysis indicated that attitudes mediate the relationships between subject norms and regulatory compliance. Additionally, SEM revealed that the independent variables of attitude, subjective norms and self-efficacy accounted for 29% variance in regulatory compliance in NUWSS. Specifically, the variables in TPB influenced regulatory compliance in NUWSS through crucial elements such as: reciprocal motivation, preferential compliance, misconceptions and ambiguity, self-discipline among others. These key factors acted as motivations or constraints on regulatory compliance in NUWSS. Further research should assess how these elements influence compliance in the water supply that is dominated by NUWSS.

Within the framework of Color Glass Condensate (CGC) effective field theory (EFT), we calculated the dijet cross sections and the azimuthal correlations by including the Sudakov resummations, numerical results shown that the back-to-back correlations are significantly suppressed when the Sudakov resummations are taken into account. In addition, by using the solutions of running-coupling Balitsky-Kovchegov (rcBK) equation, the unpolarized and linearly polarized WW gluon distributions both in coordinate and momentum space are presented.

description: We exploit the common mathematical structure of the numerical renormalization group and the density matrix renormalization group, namely, matrix product states, to implement an efficient numerical treatment of a two-lead, multi-level Anderson impurity model. By adopting a star-like geometry, where each species (spin and lead) of conduction electrons is described by its own Wilson chain, instead of using a single Wilson chain for all species together, we achieve a very significant reduction in the numerical resources required to obtain reliable results. We illustrate the power of this approach by calculating ground state properties of a four-level quantum dot coupled to two leads. The success of this proof-of-principle calculation suggests that the star geometry constitutes a promising strategy for future calculations the ground state properties of multi-band, multi-level quantum impurity models. Moreover, we show that it is possible to find an "optimal" chain basis, obtained via a unitary transformation (acting only on the index distinguishing different Wilson chains), in which degrees of freedom on different Wilson chains become effectively decoupled from each other further out on the Wilson chains. This basis turns out to also diagonalize the model's chain-to-chain scattering matrix. We demonstrate this for a spinless two-lead model, presenting DMRG-results for the mutual information between two sites located far apart on different Wilson chains, and NRG results with respect to the scattering matrix.

description: The cost of fish feeding is usually around 40 percent of total production cost. Estimating a state of fishes in a tank and adjusting an amount of nutriments play an important role to manage cost of fish feeding system. Our approach is based on tracking nutriments on videos collected from an active aquaculture fish farm. Tracking approach is applied to acknowledge movement of nutriment to understand more about the fish behavior. Recently, there has been increasing number of researchers focused on developing tracking algorithms to generate more accurate and faster determination of object. Unfortunately, recent studies have shown that efficient and robust tracking of multiple objects with complex relations remain unsolved. Hence, focusing to develop tracking algorithm in aquaculture is more challenging because tracked object has a lot of aquatic variant creatures. By following aforementioned problem, we develop tuna nutriment tracking based on the classical minimum cost problem which consistently performs well in real environment datasets. In evaluation, the proposed method achieved 21.32 pixels and 3.08 pixels for average error distance and standard deviation, respectively. Quantitative evaluation based on the data generated by human annotators shows that the proposed method is valuable for aquaculture fish farm and can be widely applied to real environment datasets.

The observed numbers of IRAGNs are comparable to predictions from previous X-ray, optical, and IR luminosity functions, for the given redshifts and IRAC flux limits. We observe a bimodal distribution in R-[4.5] color, suggesting that luminous IR-selected AGNs have either low or significant dust extinction, which may have implications for models of AGN obscuration.

Asymmetry Revisited: The Effect of Dust Attenuation and Galaxy Inclination

description: Dust attenuation of an inclined galaxy can cause additional asymmetries in observations, even if the galaxy has a perfectly symmetric structure. {Taking advantage of the integral field spectroscopic data observed by the SDSS-IV MaNGA survey, we investigate the asymmetries of the emission-line and continuum maps of star-forming disk galaxies.} We define new parameters, $A_a$ and $A_b$, to estimate the asymmetries of a galaxy about its major and minor axes, respectively. Comparing $A_a$ and $A_b$ in different inclination bins, we attempt to detect the asymmetries caused by dust. For the continuum images, we find that $A_a$ increases with the inclination, while the $A_b$ is a constant as inclination changes. Similar trends are found for $g-r$, $g-i$ and $r-i$ color images. The dependence of the asymmetry on inclination suggests a thin dust layer with a scale height smaller than the stellar populations. For the H$α$ and H$β$ images, neither $A_a$ nor $A_b$ shows a significant correlation with inclination. Also, we do not find any significant dependence of the asymmetry of $E(B-V)_g$ on inclination, implying that the dust in the thick disk component is not significant. Compared to the SKIRT simulation, the results suggest that the thin dust disk has an optical depth $τ_V\sim0.2$. This is the first time that the asymmetries caused by the dust attenuation and the inclination are probed statistically with a large sample. Our results indicate that the combination of the dust attenuation and the inclination effects is a potential indicator of the 3D disk orientation.

description: Требования современной демократии побуждают государства повысить свою ответственность в процессе регулирования государственно-конфессиональных отношений. В статье приведен обзор ответственности вьетнамского государства за решение религиозных вопросов с правовой точки зрения. Для обоснования проблемы автор провел исследование положений действующих вьетнамских правовых актов, посвященных вопросам вероисповедания. Результаты исследования показывают, что ответственность государства в сфере конфессиональных вопросов распространяется в основном на отношения государства с религиозными организациями, включает право на свободу вероисповедания, учитывает культурные ценности религии и народные верования. Несмотря на то, что во Вьетнаме наблюдается тенденция к усилению ответственности государства в отношениях между государством и конфессиями, необходимо совершенствовать законодательные положения, регулирующие данную сферу.
description: The demand of modern democracy boosts states to increase their responsibility in regulating state-religion relations. The article presents an overview of the Vietnamese state responsibility to solve religious issues from a legal perspective. To accomplish this goal, the author studied the provisions of the current Vietnamese legal acts on religion and belief. The research results demonstrate that the state responsibility for confessional matters primarily lies with relations of state with religious organizations, the right to freedom of religion, and cultural values of religion and folk beliefs. Even though there is a tendency to increase the state responsibility for relations between the state and confessions in Vietnam, it is necessary to improve the legislative provisions on this issue.

description: A novel non-destructive methodology for operando observation of ion intercalation and the state of charge on battery electrodes is presented based on spectroscopic ellipsometry (SE). The potentiality of this technique for performing time-resolved measurements of (de-)lithiation processes on electrode materials has been demonstrated using thin film spinel LiMn$_2$O$_4$ as a cathode for Li-ion batteries. The chemical diffusivity of Li+ ions in this material has been determined by the time evolution of the Li insertion into the film, and in the light of these results, it has been possible to relate the controversial pseudo-capacitive behavior observed in this material to the nanostructure of the layer. The results presented here establish a new way for operando characterization of battery materials and devices providing a powerful tool for the understanding of ion diffusion mechanisms in a collection of electrochemical devices.

Graph state invariants and the graph isomorphism problem

Year: 2020
Subjects: subject: 29999 Physical Sciences not elsewhere classified
subject: FOS: Physical sciences

description: The application of equal-angle Wigner functions (EAWF) of graph states to the graph isomorphism problem has been investigated. The method has promise as the EAWF is inherently permutation invariant and has previously been used to efficiently identify quantum states. Other quantum approaches to the problem have mainly used quantum walks or adiabatic methods and have not been based upon graph states, leaving a gap which this work makes steps to fill. The EAWFs of graph states were numerically calculated and nonisomorphic graphs were found which shared EAWFs. The reason for this degeneracy was investigated resulting in the development of a family of new graph invariants, members of which may be complete. The practicality of applying these invariants is analysed, but no polynomially efficient implementation has been found due to the difficulties associated with obtaining adequate statistics for large systems of qubits. The significance of the work is the discovery of a family of graph invariants which may offer new insight on the graph isomorphism problem.

description: R. Rimányi defined the incidence class of two singularities X and Y as $[X]|_Y$, the restriction of the Thom polynomial of X to Y. He conjectured that (under mild conditions) the incidence is not zero if and only if Y is in the closure of X. Generalizing this notion we define the incidence class of two orbits X and Y of a representation. We give a sufficient condition (positivity) for Y to have the property that the incidence class $[X]|_Y$ is not zero if and only if Y is in the closure of X for any other orbit X. We show that for many interesting cases, e.g. the quiver representations of Dynkin type positivity holds for all orbits. In other words in these cases the incidence classes completely determine the hierarchy of the orbits. We also study the case of singularities where positivity doesn't hold for all orbits.

description: Mining activities have led to Cu and Cd contaminated of surrounding agricultural soil. To decrease the Cu and Cd accumulation in crops, the Ricinus communis L. (castor) has been used for phytoremediation. A pot experiment was served to investigate the effect of phosphate fertilizer (Ca(H2PO4)2) on the growth and Cu/Cd uptake of castor in contaminated soil. The results showed that the application of P fertilizer improved the leaf cell morphology, decreased the malonaldehyde (MDA) content of castor leaves, and increased the plant biomass (28.2–34.2%). Besides, phosphate fertilizer still facilitated accumulation Cu and Cd by castor. The addition of phosphate fertilizer increased the contents of Cu in the root of castor, improved the bioconcentration factor (BCF) of Cu, and observably enhanced the accumulation of Cu (up to 201 μg/plant) in castor. Applying phosphorus increased the percentage of residual Cd, diminished the percentage of acid extractable Cd in soil, and the accumulation of Cd in castor was not significantly increased. These results suggest that phosphorus alleviated the stress of heavy metals on castor leaves and enhanced the accumulation of Cu and Cd in castor by promoting the growth of castor. Applying phosphate fertilizer effectively alleviated the stress of heavy metals on castor and significantly increased the biomass of castor.The reason of applying phosphorus enhanced the castor uptake Cu and Cd was that phosphorus promoted the growth of castor.Applying phosphorus markedly increased the percentage of residual Cd but diminished the percentage of acid extractable Cd in soil.

description: We derive energy-norm a posteriori error bounds for an Euler time-stepping method combined with various spatial discontinuous Galerkin schemes for linear parabolic problems. For accessibility, we address first the spatially semidiscrete case, and then move to the fully discrete scheme by introducing the implicit Euler time-stepping. All results are presented in an abstract setting and then illustrated with particular applications. This enables the error bounds to hold for a variety of discontinuous Galerkin methods, provided that energy-norm a posteriori error bounds for the corresponding elliptic problem are available. To illustrate the method, we apply it to the interior penalty discontinuous Galerkin method, which requires the derivation of novel a posteriori error bounds. For the analysis of the time-dependent problems we use the elliptic reconstruction technique and we deal with the nonconforming part of the error by deriving appropriate computable a posteriori bounds for it.

description: We investigate the relation between the canonical model of quantum optics, the Jaynes-Cummings Hamiltonian and Dirac fermions in quantizing magnetic field. We demonstrate that Rabi oscillations are observable in the optical response of graphene, providing us with a transparent picture about the structure of optical transitions. While the longitudinal conductivity reveals chaotic Rabi oscillations, the Hall component measures coherent ones. This opens up the possibility of investigating a microscopic model of a few quantum objects in a macroscopic experiment with tunable parameters.

Modeling Magnetic Disk-Wind State Transitions in Black Hole X-ray Binaries

description: We analyze three prototypical black hole (BH) X-ray binaries (XRBs), \4u1630, \gro1655\ and \h1743, in an effort to systematically understand the intrinsic state transition of the observed accretion-disk winds between \windon\ and \windoff\ states by utilizing state-of-the-art {\it Chandra}/HETGS archival data from multi-epoch observations. We apply our magnetically-driven wind models in the context of magnetohydrodynamic (MHD) calculations to constrain their (1) global density slope ($p$), (2) their density ($n_{17}$) at the foot point of the innermost launching radius and (3) the abundances of heavier elements ($A_{\rm Fe,S,Si}$). Incorporating the MHD winds into {\tt xstar} photoionization calculations in a self-consistent manner, we create a library of synthetic absorption spectra given the observed X-ray continua. Our analysis clearly indicates a characteristic bi-modal transition of multi-ion X-ray winds; i.e. the wind density gradient is found to steepen (from $p \sim 1.2-1.4$ to $\sim 1.4-1.5$) while its density normalization declines as the source transitions from \windon\ to \windoff\ state. The model implies that the ionized wind {\it remains physically present} even in \windoff\ state, despite its absent appearance in the observed spectra. Super-solar abundances for heavier elements are also favored. Our global multi-ion wind models, taking into account soft X-ray ions as well as Fe K absorbers, show that the internal wind condition plays an important role in wind transitions besides photoionization changes. % Simulated {\it XRISM}/Resolve and {\it Athena}/X-IFU spectra are presented to demonstrate a high fidelity of the multi-ion wind model for better understanding of these powerful ionized winds in the coming decades.

A Hypercontractive Inequality for Matrix-Valued Functions with Applications to Quantum Computing and LDCs

description: The Bonami-Beckner hypercontractive inequality is a powerful tool in Fourier analysis of real-valued functions on the Boolean cube. In this paper we present a version of this inequality for matrix-valued functions on the Boolean cube. Its proof is based on a powerful inequality by Ball, Carlen, and Lieb. We also present a number of applications. First, we analyze maps that encode $n$ classical bits into $m$ qubits, in such a way that each set of $k$ bits can be recovered with some probability by an appropriate measurement on the quantum encoding; we show that if $m<0.7 n$, then the success probability is exponentially small in $k$. This result may be viewed as a direct product version of Nayak's quantum random access code bound. It in turn implies strong direct product theorems for the one-way quantum communication complexity of Disjointness and other problems. Second, we prove that error-correcting codes that are locally decodable with 2 queries require length exponential in the length of the encoded string. This gives what is arguably the first ``non-quantum'' proof of a result originally derived by Kerenidis and de Wolf using quantum information theory, and answers a question by Trevisan.

description: In this article, we first investigate the kinematics of specific geodesic flows on two dimensional media with constant curvature, by explicitly solving the evolution (Raychaudhuri) equations for the expansion, shear and rotation along the flows. We point out the existence of singular (within a finite value of the time parameter) and non-singular solutions and illustrate our results through a `phase' diagram. This diagram demonstrates under which initial conditions (or combinations thereof) we end up with a singularity in the congruence and when, if at all, we encounter non--singular solutions for the kinematic variables. Our analysis illustrates the differences which arise due to a positive or negative value of the curvature. Subsequently, we move on to geodesic flows on two dimensional spaces with varying curvature. As an example, we discuss flows on a torus, where interesting oscillatory features of the expansion, shear and rotation emerge, which are found to depend on the ratio of the radii of the torus. The singular (within a finite time)/non--singular nature of the solutions are also discussed. Finally, we arrive at some general statements and point out similarities or dissimilarities that arise in comparison to our earlier work on media in flat space.

A contribution to the computer aided design of optimized structures for the steel industry

description: A practical method of incorporating realistic flexible connections including the effect of connection sizes and shear deflection in plane frame analysis is presented. The general algorithm can be easily implemented in a standard plane frame analysis program and once implemented it can be an ideal tool for production work in the steel industry. In this approach connection stiffness is programmed directly into the analysis by utilizing the connection moment-rotation equations developed by Frye and Morris but it may also be entered separately as data. Nonlinear connection analysis is carried out by the procedure outlined by Frye and Morris. Practical application of this method of analysis is demonstrated by modifying a standard plane frame analysis program to include the effect of flexible connections. The validity of the modified program, CPlane, was verified against the findings of Moncarz and Gerstle. Using CPlane, a simple plane frame structure was analyzed under various lateral load intensities for different connection assumptions. It was found that the inclusion of connection behavior significantly altered the internal force distribution and design of the structure.
Detection of heavy metal ions using resistive pulse sensors

description: The main goal of this PhD was to expand the library of potential aptamers which can be used with Resistive Pulse Sensing (RPS) to enable a wider range of target analytes to be detected. Although RPS has been extensively applied with DNA aptamers for the detection of many different targets, including heavy metal ions, there are still many metal ions for which there are no known DNA aptamers. Here the focus was on the development of methods which utilise peptide aptamers and DNAzymes with RPS to expand this library. Further, the project looked to transfer the developed assays onto paper-based devices (PADs) to move towards a low-cost portable device. The first chapter presents a brief introduction to the nuclear decommissioning within the UK and how the NDA operates. It aims to provide some background to the overall aims of the project through outlining some of the current separation and analytical techniques which are employed for sample characterisation. The sensing methods used during this project were RPS and Ion Current Rectification (ICR) the literature review in chapter 2 focuses on the key aspects of these methods. The first project, outlined within in chapter 4, reports the first use of peptidecovered nanoparticles for the detection of nickel ions. It demonstrates how charge can be built into the peptides and showed a relationship between particle speed and concentration of nickel present. The specificity of the assay was established through incubation with a range of metal ions before finally the assay was then applied in real world samples through measuring nickel in dosed tap and pond water. Chapter 5 applies already designed DNAzymes to the detection of calcium ions. RPS was able to follow the structure changes of the DNAzyme, caused by the binding of calcium ions. The assay was shown to be catalytic in nature and allowed for tunability through incubation times. Again, the specificity of the assay was established through incubation with a range of metal ions before the assay was tested in real work samples. 3 Finally, presented in chapter six, is the use of PADs coated in different recognition elements for the detection of multiple metal ions simultaneously. The assay was able to indicate the presence of nickel, mercury and lead through changes in the current measured. The assays specificity and ability to work within environmental samples was also confirmed. The PADs were able to detect the three metal ions simultaneously. To summarise, the work presented within this thesis has expanded the library of potential aptamers that can be applied within RPS, hence expanding the library of potential targets for RPS. It has also developed a method which utilises ICR as the sensor and is able to measure multiple ions simultaneously. Through the work developed here, three published journal papers have been achieved and the work has been presented at several conferences.
