description: For dielectric multilayered metamaterials, the effective-parameter representation is known to be insensitive to geometrical features occurring at deeply subwavelength scales. However, recent studies on periodic and aperiodically ordered geometries have shown the existence of certain critical parameter regimes where this conventional wisdom is upended, as the optical response of finite-size samples may depart considerably from the predictions of standard effective-medium theory. In these regimes, characterized by a mixed evanescent/propagating light transport, different classes of spatial (dis)order have been shown to induce distinctive effects in the optical response, in terms of anomalous transmission, localization, enhancement, absorption and lasing. Here, we further expand these examples by considering a quasiperiodic scenario based on a modified-Fibonacci geometry. Among the intriguing features of this model there is the presence of a scale parameter that controls the transition from perfectly periodic to quasiperiodic scenarios of different shades. Via an extensive parametric study, this allows us to identify the quasiperiodicity-induced anomalous effects, and to elucidate certain distinctive mechanisms and footprints. Our results hold potentially interesting implications for the optical probing of structural features at a resolution much smaller than the wavelength, and could also be leveraged to design novel types of absorbers and low-threshold lasers.

description: "Que el poblador principal tome asiento con cada particular que se register para poblar" è il titolo di uno degli ordini di popolazione stabiliti da Filippo II nel 1573 e successivamente compilato nel 1681 come parte delle cosiddette Leyes de Indias. L'applicazione di questo principio durante la prima modernità su entrambe le sponde dell'Atlantico può essere intesa sia come un prodotto dell'evoluzione di pratiche precedenti sia come una conseguenza del costante scambio transatlantico di idee. Questo capitolo esplora una selezione di documenti legali e protocolli di fondazione urbana che vanno in entrambe le direzioni, attraverso esempi in Andalusia (Spagna), Cuyo (Argentina) e Boyacá (Colombia).

«Que el poblador principal tome asiento con cada particular que se registrare para poblar» is the heading of one of the 1573 population orders enacted by Phillip II and later compiled on 1681 as part of the Indies Laws or Leyes de Indias. The use of this principle on both sides of the Atlantic across the early modern period can be understood both as an evolution of previous practices and the result of a constant exchange of transatlantic ideas. This chapter explores a selection of legal records and urban foundation protocols pointing in that direction, with examples in Andalusia (Spain), Cuyo (Argentina), and Boyacá (Colombia).

Experimental study of the compaction dynamics for 2D anisotropic granular materials

description: We present an experimental study of the compaction dynamics for two-dimensional anisotropic granular systems. Compaction dynamics is measured at three different scales : (i) the macroscopic scale through the packing fraction $ρ$, (ii) the mesoscopic scale through both fractions of aligned grains $ϕ_{a}$ and ideally ordered grains $ϕ_{io}$, and (iii) the microscopic scale through both rotational and translational grain mobilities $μ_{r,t}$. The effect of the grain rotations on the compaction dynamics has been measured. At the macroscopic scale, we have observed a discontinuity in the late stages of the compaction curve. At the mesoscopic scale, we have observed the formation and the growth of domains made of aligned grains. From a microscopic point of view, measurements reveal that the beginning of the compaction process is essentially related to translational motion of the grains. The grains rotations drive mainly the process during the latest stages of compaction.

Oxidized low density lipoprotein mediated macrophage survival : an essential role for PI3K/PKB pathway
Creators: name: Hundal, Rajinder Singh
Publisher: name: University of British Columbia
Year: 2009

description: Oxidized LDL (ox-LDL) has previously been shown to induce endothelial adhesion molecule, MCP-1 and M-CSF expression thereby leading to monocyte recruitment, adherence and macrophage differentiation and has recently been shown to induce macrophage proliferation. The purpose of this study was to examine an additional mechanism by which ox-LDL might increase macrophage populations - enhanced macrophage survival. I found that ox-LDL caused a dose-dependent inhibition of the apoptosis that occurs in cultured bone marrow-derived macrophages following M-CSF withdrawal. Incubation of macrophages with either native LDL or acetylated LDL had no effect on survival, thereby suggesting an oxidation specific event. The pro-survival effect of ox-LDL was not inhibited by neutralizing antibodies to GM-CSF, was maintained in mice homozygous for a mutation in the M-CSF gene, and was not due to other secreted cytokines or growth factors. This suggested that ox-LDL activated cytokine-independent intracellular survival signaling pathways. Ox-LDL caused activation of the MAP kinases ERK1/2 as well as protein kinase B (PKB), a target of phosphatidylinositol 3-kinase (PI3K). Furthermore, there was phosphorylation of two important PKB downstream targets lкB-α-Ser-32 and Bad- Ser-136, both of which act at the level of the pro-survival Bcl-2 protein, Bcl-Xι to inhibit apoptosis. The MEK inhibitors PD 98059 and U0126 blocked ERK1/2 activation, but did not diminish survival. Conversely, the PI3K inhibitors LY 294002 and wortmannin blocked PKB activation, and the ability of ox-LDL to promote macrophage survival. I also demonstrated that ox-LDL prevented the elaboration of ceramide following the withdrawal of M - CSF, and pre-treatment with soluble ceramides attenuated ox-LDL mediated macrophage survival and PKB activation. The source of ceramide elaboration was through the metabolism of sphingomyelin to ceramide rather than de novo synthesis as determined by inhibitor studies with fumonisin BI and desipramine; as well as by determination of levels of sphingomyelin. Ox-LDL was also able to prevent the decline in the levels of Bcl-XLthat occur following M - CSF withdrawal. Taken together, these results indicate that ox-LDL prevents ceramide elaboration, activates a PI3K/PKB pathway that reduces cytosolic sequestration of NF-кB , as well as phosphorylates Bad and thereby promotes macrophage survival in the absence of growth factors at the level of Bcl-Xι and caspase 3 activation.

description: An important task for Homeland Security is the prediction of threat vulnerabilities, such as through the detection of relationships between seemingly disjoint entities. A structure used for this task is a "semantic graph", also known as a "relational data graph" or an "attributed relational graph". These graphs encode relationships as "typed" links between a pair of "typed" nodes. Indeed, semantic graphs are very similar to semantic networks used in AI. The node and link types are related through an ontology graph (also known as a schema). Furthermore, each node has a set of attributes associated with it (e.g., "age" may be an attribute of a node of type "person"). Unfortunately, the selection of types and attributes for both nodes and links depends on human expertise and is somewhat subjective and even arbitrary. This subjectiveness introduces biases into any algorithm that operates on semantic graphs. Here, we raise some knowledge representation issues for semantic graphs and provide some possible solutions using recently developed ideas in the field of complex networks. In particular, we use the concept of transitivity to evaluate the relevance of individual links in the semantic graph for detecting relationships. We also propose new statistical measures for semantic graphs and illustrate these semantic measures on graphs constructed from movies and terrorism data.

description: The enterprise budget, whole farm cash flow, and income statement are fundamental tools of farm and ranch management. The "Microcomputer Budget Management System" (MBMS) is a microcomputer software package that facilitates the storage and use of information for crop and livestock budgeting. It performs the calculations for several enterprise budgeting formats and for preparation of whole farm resource use reports and financial statements. The MBMS also includes internal machinery and irrigation cost calculation routines. MBMS was developed for use by extension staff, researchers, lenders, consultants, and operators of diversified farms and ranches with many enterprises that use enterprise and whole farm budgeting for analysis and planning activities. The flexibility and detailed nature of the program requires the user to have knowledge of enterprise budgeting and operation of complex computer programs. This paper presents a discussion of the features and capabilities of the software and the computational procedures used in the cost calculations.
Nonadditivity of Polymeric and Charged Surface Interactions: Consequences for Doped Lamellar Phases

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: We explore theoretically the modifications to the interactions between charged surfaces across an ionic solution caused by the presence of dielectric polymers. Although the chains are neutral, the polymer physics and the electrostatics are coupled; the intra-surface electric fields polarise any low permittivity species (e.g., polymer) dissolved in a high permittivity solvent (e.g., water). This coupling enhances the polymer depletion from the surfaces and increases the screening of electrostatic interactions with respect to a model which treats polymeric and electrostatic effects as independent. As a result, the range of the ionic contribution to the osmotic interaction between surfaces is decreased, while that of the polymeric contribution is increased. These changes modify the total interaction in a nonadditive manner. Building on the results for parallel surfaces, we investigate the effect of this coupling on the phase behaviour of polymer-doped smectics.

description: Capabilities of quantum optical SFG-gate seeded by squeezed light are investigated in the frame of frequency Schmidt modes. Methods to manage and manipulate extensively the properties and mode content of squeezed light are developed. Possibilities to block and select any certain Schmidt mode of squeezed light with conservation of non-classical properties are demonstrated. The significant phase sensitivity of the gate is shown and the ways to manage the spectral distribution of the output light due to the phase effects and variable coupling between modes in the gate are demonstrated. The effect of swapping between modes in the gate is found. It allows to enhance squeezed light in a set of modes without loss of photon correlations which is important for further experiments and new applications.

description: We present a theoretical study of vortices in arrays of photon condensates. Even when interactions are negligible, as is the case in current experiments, pumping and losses can lead to a finite vortex core size. While some properties of photon condensate vortices, such as their self-acceleration and the generation of vortex pairs by a moving vortex, resemble those in interacting polariton condensates far from equilibrium, in several aspects they differ from previously studied systems: the vortex core size is determined by the balance between pumping and tunneling, the core appears oblate in the direction of its motion and new vortex pairs can spontaneously nucleate in the core region.

description: Stardust grains that originated in ancient stars and supernovae are recovered from meteorites and carry the detailed composition of their astronomical sites of origin. We present evidence that the majority of large ($μ$m-sized) meteoritic silicon carbide (SiC) grains formed in C-rich asymptotic giant branch (AGB) stars that were more metal-rich than the Sun. In the framework of the slow neutron-captures (the s process) that occurs in AGB stars the lower-than-solar 88Sr/86Sr isotopic ratios measured in the large SiC grains can only be accompanied by Ce/Y elemental ratios that are also lower than solar, and predominately observed in metal-rich barium stars - the binary companions of AGB stars. Such an origin suggests that these large grains represent the material from high-metallicity AGB stars needed to explain the s-process nucleosynthesis variations observed in bulk meteorites (Ek et al. 2020). In the outflows of metal-rich, C-rich AGB stars SiC grains are predicted to be small ($\simeq$ 0.2 $μ$m-sized); large ($\simeq$ $μ$m-sized) SiC grains can grow if the number of dust seeds is two to three orders of magnitude lower than the standard value of $10^{-13}$ times the number of H atoms. We therefore predict that with increasing metallicity the number of dust seeds might decrease, resulting in the production of larger SiC grains.

description: Previous studies have consistently indicated the anomalous result of a price inflexible demand for pecans. However, these efforts did not have an adequate measure of pecan stocks available and, as a result, stocks were either excluded from consideration or a proxy variable was introduced. A time series of pecan stocks is now available. Use of this time series in a price dependent demand function results in a flexible farm level demand for pecans. This points out the danger of excluding an appropriate variable or using a so-called "reasonable" proxy variable.

description: We investigate a systematic approach to include curvature corrections to the isometry algebra of flat space-time order-by-order in the curvature scale. The Poincaré algebra is extended to a free Lie algebra, with generalised boosts and translations that no longer commute. The additional generators satisfy a level-ordering and encode the curvature corrections at that order. This eventually results in an infinite-dimensional algebra that we refer to as Poincaré${}_\infty$, and we show that it contains among others an (A)dS quotient. We discuss a non-linear realisation of this infinite-dimensional algebra, and construct a particle action based on it. The latter yields a geodesic equation that includes (A)dS curvature corrections at every order.

description: Separating benign domains from domains generated by DGAs with the help of a binary classifier is a well-studied problem for which promising performance results have been published. The corresponding multiclass task of determining the exact DGA that generated a domain enabling targeted remediation measures is less well studied. Selecting the most promising classifier for these tasks in practice raises a number of questions that have not been addressed in prior work so far. These include the questions on which traffic to train in which network and when, just as well as how to assess robustness against adversarial attacks. Moreover, it is unclear which features lead a classifier to a decision and whether the classifiers are real-time capable. In this paper, we address these issues and thus contribute to bringing DGA detection classifiers closer to practical use. In this context, we propose one novel classifier based on residual neural networks for each of the two tasks and extensively evaluate them as well as previously proposed classifiers in a unified setting. We not only evaluate their classification performance but also compare them with respect to explainability, robustness, and training and classification speed. Finally, we show that our newly proposed binary classifier generalizes well to other networks, is time-robust, and able to identify previously unknown DGAs.

The Minimal Helicity of Solar Coronal Magnetic Fields

description: Potential field extrapolations are widely used as minimum-energy models for the Sun's coronal magnetic field. As the reference to which other magnetic fields are compared, they have -- by any reasonable definition -- no global (signed) magnetic helicity. Here we investigate the internal topological structure that is not captured by the global helicity integral, by splitting it into individual field line helicities. These are computed using potential field extrapolations from magnetogram observations over Solar Cycle 24, as well as for a simple illustrative model of a single bipolar region in a dipolar background. We find that localised patches of field line helicity arise primarily from linking between strong active regions and their overlying field, so that the total unsigned helicity correlates with the product of photospheric and open fluxes. Within each active region, positive and negative helicity may be unbalanced, but the signed helicity is only around a tenth of the unsigned helicity. Interestingly, in Cycle 24, there is a notable peak in unsigned helicity caused by a single large active region. On average, the total unsigned helicity at the resolution considered is approximately twice the typical signed helicity of a single real active region, according to non-potential models in the literature.

From our data we extract the pressure response of the antiferromagnetic phase transition at T0 = 11.6 K and of the overall magnetic coupling strength. Our experiments indicate that with pressure the overall magnetic coupling strength increases by about 25% with applied pressure of only 8 kbar. In contrast, the phase transition temperature T0 is significantly suppressed and not observable anymore at a pressure of already 8.2 kbar.

description: Classifiers are often tested on relatively small data sets, which should lead to uncertain performance metrics. Nevertheless, these metrics are usually taken at face value. We present an approach to quantify the uncertainty of classification performance metrics, based on a probability model of the confusion matrix. Application of our approach to classifiers from the scientific literature and a classification competition shows that uncertainties can be surprisingly large and limit performance evaluation. In fact, some published classifiers are likely to be misleading. The application of our approach is simple and requires only the confusion matrix. It is agnostic of the underlying classifier. Our method can also be used for the estimation of sample sizes that achieve a desired precision of a performance metric.

description: We give explicit formulas for Hadamard's coefficients in terms of the tau-function of the KdV hierarchy. We show that some of the basic properties of these coefficients can be easily derived from these formulas. The first immediate corollary is the symmetry of Hadamard's coefficients about the diagonal. Another well known fact, which follows from this approach, is that on the diagonal Hadamard's coefficients determine the right-hand sides of the equations of the KdV hierarchy. The proof of the main result uses Sato theory and simple properties of Gegenbauer polynomials.

description: Electrical manipulation of skyrmions attracts considerable attention for its rich physics and promising applications. To date, such a manipulation is realized mainly via spin-polarized current based on spin-transfer torque or spin-orbital torque effect. However, this scheme is energy-consuming and may produce massive Joule heating. To reduce energy dissipation and risk of heightened temperatures of skyrmion-based devices, an effective solution is to use electric field instead of current as stimulus. Here, we realize an electric-field manipulation of skyrmions in a nanostructured ferromagnetic/ferroelectrical heterostructure at room temperature via an inverse magneto-mechanical effect. Intriguingly, such a manipulation is non-volatile and exhibits a multi-state feature. Numerical simulations indicate that the electric-field manipulation of skyrmions originates from strain-mediated modification of effective magnetic anisotropy and Dzyaloshinskii-Moriya interaction. Our results open a direction for constructing low-energy-dissipation, non-volatile, and multi-state skyrmion-based spintronic devices.

description: Behavior of static axially symmetric monopole-antimonopole and vortex ring solutions of the SU(2) Yang-Mills-Higgs theory in an external uniform magnetic field is considered. It is argued that the axially symmetric monopole-antimonopole chains and vortex rings can be treated as a bounded electromagnetic system of the magnetic charges and the electric current rings. The magnitude of the external field is a parameter which may be used to test the structure of the static potential of the effective electromagnetic interaction between the monopoles with opposite orientation in the group space. It is shown that for a non-BPS solutions there is a local minimum of this potential.

On the Polyharmonic Operator with a Periodic Potential
Creators: name: Veliev, O. A.
Publisher: name: arXiv

description: In this paper we obtain the asymptotic formulas of arbitrary order for the Bloch eigenvalues and Bloch functions of the multidimensional polyharmonic operator with periodic, with respect to arbitrary lattice, potential. Then we prove that the number of gaps in the spectrum of the operator is finite. In particular, we get the proof of the Bethe -Sommerfeld conjecture for arbitrary dimension and arbitrary lattice.

description: In experiments and applications usually the spin magnetic moment of magnons is considered. In this Paper we identify an additional degree of freedom of magnons: an \emph{orbital} magnetic moment brought about by spin-orbit coupling.Our microscopic theory uncovers that spin magnetization $\vec{M}^\mathrm{S}$ and orbital magnetization $\vec{M}^\mathrm{O}$ are independent quantities. They are not necessarily collinear; thus, even when the total spin moment is compensated due to antiferromagnetism ($\vec{M}^\mathrm{S} = \vec{0}$), $\vec{M}^\mathrm{O}$ may be nonzero. This scenario of orbital weak ferromagnetism is realized in paradigmatic kagome antiferromagnets with Dzyaloshinskii-Moriya interaction. We demonstrate that magnets exhibiting a magnonic orbital moment are omnipresent and propose transport experiments for probing it.
The role of elliptic flow correlations in the discovery of the sQGP at RHIC
Creators: name: Lacey, Roy A.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Flow measurements are reviewed with particular emphasis on the hydrodynamic character of elliptic flow at RHIC. Hydrodynamic scaling compatible with the production of highly thermalized matter having a high degree of collective interactions and extremely low viscosity, is observed for a broad selection of the data. These properties suggest the production of a new state of strongly interacting nuclear matter at extremely high density and temperature where the relevant degrees of freedom are those of quarks and gluons, ie. the sQGP.

description: The Euler characteristic $χ=|V|-|E|$ and the total length $\mathcal{L}$ are the most important topological and geometrical characteristics of a metric graph. Here, $|V|$ and $|E|$ denote the number of vertices and edges of a graph. The Euler characteristic determines the number $β$ of independent cycles in a graph while the total length determines the asymptotic behavior of the energy eigenvalues via the Weyl's law. We show theoretically and confirm experimentally that the Euler characteristic can be determined (heard) from a finite sequence of the lowest eigenenergies $λ_1, \ldots, λ_N$ of a simple quantum graph, without any need to inspect the system visually. In the experiment quantum graphs are simulated by microwave networks. We demonstrate that the sequence of the lowest resonances of microwave networks with $β\leq 3$ can be directly used in determining whether a network is planar, i.e., can be embedded in the plane. Moreover, we show that the measured Euler characteristic $χ$ can be used as a sensitive revealer of the fully connected graphs.
Finite heat kernel expansions on the real line

description: Let L=d^2/dx^2+u(x) be the one-dimensional Schrodinger operator and H(x,y,t) be the corresponding heat kernel. We prove that the nth Hadamard's coefficient H_n(x,y) is equal to 0 if and only if there exists a differential operator M of order 2n-1 such that L^{2n-1}=M^2. Thus, the heat expansion is finite if and only if the potential u(x) is a rational solution of the KdV hierarchy decaying at infinity studied in [1,2]. Equivalently, one can characterize the corresponding operators L as the rank one bispectral family in [8].

Quantum chaos algorithms and dissipative decoherence with quantum trajectories
Creators: name: Lee, Jae Weon
name: Shepelyansky, Dima L.
Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Using the methods of quantum trajectories we investigate the effects of dissipative decoherence in a quantum computer algorithm simulating dynamics in various regimes of quantum chaos including dynamical localization, quantum ergodic regime and quasi-integrable motion. As an example we use the quantum sawtooth algorithm which can be implemented in a polynomial number of quantum gates. It is shown that the fidelity of quantum computation decays exponentially with time and that the decay rate is proportional to the number of qubits, number of quantum gates and per gate dissipation rate induced by external decoherence. In the limit of strong dissipation the quantum algorithm generates a quantum attractor which may have complex or simple structure. We also compare the effects of dissipative decoherence with the effects of static imperfections.

A Reinforcement Learning Approach for Transient Control of Liquid Rocket Engines

description: Nowadays, liquid rocket engines use closed-loop control at most near steady operating conditions. The control of the transient phases is traditionally performed in open-loop due to highly nonlinear system dynamics. This situation is unsatisfactory, in particular for reusable engines. The open-loop control system cannot provide optimal engine performance due to external disturbances or the degeneration of engine components over time. In this paper, we study a deep reinforcement learning approach for optimal control of a generic gas-generator engine's continuous start-up phase. It is shown that the learned policy can reach different steady-state operating points and convincingly adapt to changing system parameters. A quantitative comparison with carefully tuned open-loop sequences and PID controllers is included. The deep reinforcement learning controller achieves the highest performance and requires only minimal computational effort to calculate the control action, which is a big advantage over approaches that require online optimization, such as model predictive control. control.

description: We present the matching condition for the strong coupling contant alpha_s at a heavy quark threshold to four loops in the modified minimal subtraction scheme. Our results lead to further decrease of the theoretical uncertainty of the evolution of the strong coupling constant through heavy quark thresholds. Using a low energy theorem we furthermore derive the effective coupling of the Higgs boson to gluons (induced by a virtual heavy quark) in four- and (partially) through five-loop approximation.

Essays in asset pricing
Creators: name: Garlappi, Lorenzo
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation consists of two essays dealing with two selected aspects of the investment decision process faced by individuals and corporations. In the first essay, I develop a model of a multiple-stage patent race between two rival firms to study the impact of technological competition on value and return dynamics of Research and Development (R&D) ventures. The model describes a firm's capital budgeting decision process in the presence of technical uncertainty, market uncertainty and preemption. I characterize the equilibrium of the race and derive optimal investment strategies. Analysis of the equilibrium firm value shows that the premium accruing to the technology "leader" is larger than the loss accruing to the technology "lagger" and that the marginal effect of success/failure is increasing in the uncertainty of cash flows. Risk premia demanded by an ownership claim to competing R&D ventures (i) increase when a rival pulls ahead in the race and (ii) are lower when rivals are "closer" to each other in the development process. Compared to the case where rival firms merge, R&D competition reduces the industry value and lowers the expected completion time for a project. The erosion in value, due to preemption, is higher when firms are "neck-and-neck" and in early stages of development. Numerical simulations show that, in later stages of development, risk premia demanded by the perfectly collusive market are generally lower than risk premia demanded by a portfolio of competing firms. The opposite is true in early stages of development, which suggests that R&D competition may actually lower the cost of early stage financing. In the second essay, I solve a portfolio allocation problem for an individual who can select between two risky assets and a riskless asset in the presence of capital gains taxes. I treat capital gains taxes as a form of endogenous transaction costs. Using this analogy, I characterize the trading strategy for the two assets, and study the effect of taxes on optimal portfolio diversification. The optimal strategy contains a "no trade" region and a dynamic tax-timing option. I find that the diversification costs due to capital gains taxes are substantial and the value of the tax deferral option is decreasing in the correlation among assets and in the volatility of the risky assets. By comparing the solution of the multiple asset portfolio problem to the one of an investor who can trade only in a mutual fund I am able to measure the value of the flexibility option of the multi-asset case as well as the cost of mutual fund turnover. Finally, I show that imposing a wash-sale constraint generates discontinuous portfolio rebalancing strategies.
