description: We extend the analysis of the effects of electromagnetic (EM) fields on mesoscopic conductors to include the effects of field quantization, motivated by recent experiments on circuit QED. We show that in general there is a photovoltaic (PV) current induced by quantized cavity modes at zero bias across the conductor. This current depends on the average photon occupation number and vanishes identically when it is equal to the average number of thermal electron-hole pairs. We analyze in detail the case of a chaotic quantum dot at temperature T_e in contact with a thermal EM field at temperature T_f, calculating the RMS size of the PV current as a function of the temperature difference, finding an effect ~pA.

Dualizing sup-preserving endomaps of a complete lattice

subject: FOS: Computer and information sciences

description: It is argued in (Eklund et al., 2018) that the quantale [L,L] of sup-preserving endomaps of a complete lattice L is a Girard quantale exactly when L is completely distributive. We have argued in (Santocanale, 2020) that this Girard quantale structure arises from the dual quantale of inf-preserving endomaps of L via Raney's transforms and extends to a Girard quantaloid structure on the full subcategory of SLatt (the category of complete lattices and sup-preserving maps) whose objects are the completely distributive lattices. It is the goal of this talk to illustrate further this connection between the quantale structure, Raney's transforms, and complete distributivity. Raney's transforms are indeed mix maps in the isomix category SLatt and most of the theory can be developed relying on naturality of these maps. We complete then the remarks on cyclic elements of [L,L] developed in (Santocanale, 2020) by investigating its dualizing elements. We argue that if [L,L] has the structure a Frobenius quantale, that is, if it has a dualizing element, not necessarily a cyclic one, then L is once more completely distributive. It follows then from a general statement on involutive residuated lattices that there is a bijection between dualizing elements of [L,L] and automorphisms of L. Finally, we also argue that if L is finite and [L,L] is autodual, then L is distributive.

Polynomial Filtering for Fast Convergence in Distributed Consensus
Creators: name: Kokiopoulou, Effrosyni

Year: 2008
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In the past few years, the problem of distributed consensus has received a lot of attention, particularly in the framework of ad hoc sensor networks. Most methods proposed in the literature address the consensus averaging problem by distributed linear iterative algorithms, with asymptotic convergence of the consensus solution. The convergence rate of such distributed algorithms typically depends on the network topology and the weights given to the edges between neighboring sensors, as described by the network matrix. In this paper, we propose to accelerate the convergence rate for given network matrices by the use of polynomial filtering algorithms. The main idea of the proposed methodology is to apply a polynomial filter on the network matrix that will shape its spectrum in order to increase the convergence rate. Such an algorithm is equivalent to periodic updates in each of the sensors by aggregating a few of its previous estimates. We formulate the computation of the coefficients of the optimal polynomial as a semi-definite program that can be efficiently and globally solved for both static and dynamic network topologies. We finally provide simulation results that demonstrate the effectiveness of the proposed solutions in accelerating the convergence of distributed consensus averaging problems.

description: Based on the notion of experiments as “Experimentalsysteme” (Rheinberger) explicated by recent history of science studies the following paper examines how experiments are conducted in and are relevant to Robert Musil’s modern novel Der Mann ohne Eigenschaften on a thematic, textual, epistemological and poetological level. Focus areas are representa­tions of different experimental constellations, i.e. scientific, poetic and thought experi­ments, the relation of experimental literary operations and scientific experimentation as well as Musil’s understanding of essayism as an experimental configuration between science and aesthetics.

description: Results are presented of single crystal structural, thermodynamic, and reflectivity measurements of the double-perovskite Ba2NaOsO6. These characterize the material as a 5d^1 ferromagnetic Mott insulator with an ordered moment of ~0.2 Bohr magnetons per formula unit and TC = 6.8(3) K. The magnetic entropy associated with this phase transition is close to Rln2, indicating that the quartet groundstate anticipated from consideration of the crystal structure is split, consistent with a scenario in which the ferromagnetism is associated with orbital ordering.

description: We study the rheological properties of a granular suspension subject to constant shear stress by constant volume molecular dynamics simulations. We derive the system `flow diagram' in the volume fraction/stress plane $(ϕ,F)$: at low $ϕ$ the flow is disordered, with the viscosity obeying a Bagnold-like scaling only at small $F$ and diverging as the jamming point is approached; if the shear stress is strong enough, at higher $ϕ$ an ordered flow regime is found, the order/disorder transition being marked by a sharp drop of the viscosity. A broad jamming region is also observed where, in analogy with the glassy region of thermal systems, slow dynamics followed by kinetic arrest occurs when the ordering transition is prevented.

Numerical Black Hole Solutions in Modified Gravity Theories: Axial Symmetry Case

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: We extend a recently developed numerical code to obtain stationary, axisymmetric solutions that describe rotating black hole spacetimes in a wide class of modified theories of gravity. The code utilizes a relaxed Newton-Raphson method to solve the full nonlinear modified Einstein's Equations on a two-dimensional grid with a Newton polynomial finite difference scheme. We validate this code by considering static and axisymmetric black holes in General Relativity. We obtain rotating black hole solutions in scalar-Gauss-Bonnet gravity with a linear (linear scalar-Gauss-Bonnet) and an exponential (Einstein-dilaton-Gauss-Bonnet) coupling and compare them to analytical and numerical perturbative solutions. From these numerical solutions, we construct a fitted analytical model and study observable properties calculated from the numerical results.

description: We consider certain decision problems for the free model of the theory of Cartesian monoids. We introduce a model of computation based on the notion of a single stack one-way PDA due to Ginsburg, Greibach and Harrison. This model allows us to solve problems such as (1) Given a finite set B of elements and an element F, is F a product of members of B? (2) Is the submonoid generated by the finite set B infinite? for certain fragments of the free Cartesian monoid. These fragments include the submonoid of right invertible elements and so our results apply to the Thompson-Higman groups.

Nature in the city : an exploration of urban park planning in response to contemporary relationships with the natural environment
Creators: name: VanSiri, Gae
Publisher: name: University of British Columbia
Year: 2009

description: One of the fundamental roles that urban parks play is to serve as a reflection of public sentiment concerning relationships with nature. Within a shared social context, each person comes to her or his own understanding of an agreeable way to interact with the urban natural environment. The construction of this understanding is dynamic. It occurs as an ongoing process of internalization of culturally determined ethical perspectives and of reflection on experiences created through individual circumstance. Differences in this understanding shape different expectations for what is an appropriate way to relate to urban nature. Addressing the array of simultaneously occurring expectations the public has for experiencing nature in the city is an-ongoing project in the planning and design of urban parks. This study makes a significant contribution to the challenges facing park planning in North America by documenting public ideas about the purpose, intent and use of urban natural area park land. It suggests a model for understanding the various relationships people have with the natural environment. The study suggests, as well, that the romanticized view of wilderness is profoundly influential in shaping urban nature. These concerns are explored within the general theoretical context of ideas about nature and creating meaning from experiences, and through analysis of results of a public survey conducted in Calgary, Alberta. The model developed in this study presents a psychographic profile of four basic modes of interacting with nature and explains how these relationships are reflected in expectations for the provision of urban nature experiences. The Consumer, Adventurer, Steward and Guardian all are oriented differently toward the planning, care and management of urban natural area park land. Together they form a composite outlook on the urban natural environment that can best be described as cautious consumption. The study raises the possibility that subsequent research could work to explore shared expectations among the various orientations, especially concerning whether to leave more park land in a natural state or to continue to provide the traditional variety of park types in urban communities. It stresses the need to broaden planning goals to attend to sociocultural, biophysical, and psychological aspects of urban natural area parks.

description: Synthesis of long-term human motion skeleton sequences is essential to aid human-centric video generation with potential applications in Augmented Reality, 3D character animations, pedestrian trajectory prediction, etc. Long-term human motion synthesis is a challenging task due to multiple factors like, long-term temporal dependencies among poses, cyclic repetition across poses, bi-directional and multi-scale dependencies among poses, variable speed of actions, and a large as well as partially overlapping space of temporal pose variations across multiple class/types of human activities. This paper aims to address these challenges to synthesize a long-term (> 6000 ms) human motion trajectory across a large variety of human activity classes (>50). We propose a two-stage activity generation method to achieve this goal, where the first stage deals with learning the long-term global pose dependencies in activity sequences by learning to synthesize a sparse motion trajectory while the second stage addresses the generation of dense motion trajectories taking the output of the first stage. We demonstrate the superiority of the proposed method over SOTA methods using various quantitative evaluation metrics on publicly available datasets.

description: The period histograms of eclipsing binaries generated with ASAS data cannot only be interpreted by orbital evolution. The eclipse probabilities, selection effects and space distributions in the solar neighborhood should be considered before any interpretations are made. Depending upon physical dimensions (total mass and period) of the progenitor stars and the efficiency of angular momentum loss (AML) mechanism, a newly formed W UMa type binary can be at any age up to several Gyr, and evolution in the contact stage is controlled not only by angular momentum and mass loss but also by mass transfer between the component stars. Thus, mean life of contact stages should be about 1.6 Gyr. A different time scale would cause inconsistencies.

Computational capacity of pyramidal neurons in the cerebral cortex

description: The electric activities of cortical pyramidal neurons are supported by structurally stable, morphologically complex axo-dendritic trees. Anatomical differences between axons and dendrites in regard to their length or caliber reflect the underlying functional specializations, for input or output of neural information, respectively. For a proper assessment of the computational capacity of pyramidal neurons, we have analyzed an extensive dataset of three-dimensional digital reconstructions from the NeuroMorpho.Org database, and quantified basic dendritic or axonal morphometric measures in different regions and layers of the mouse, rat or human cerebral cortex. Physical estimates of the total number and type of ions involved in neuronal electric spiking based on the obtained morphometric data, combined with energetics of neurotransmitter release and signaling fueled by glucose consumed by the active brain, support highly efficient cerebral computation performed at the thermodynamically allowed Landauer limit for implementation of irreversible logical operations. Individual proton tunneling events in voltage-sensing S4 protein $α$-helices of Na$^{+}$, K$^{+}$ or Ca$^{2+}$ ion channels are ideally suited to serve as single Landauer elementary logical operations that are then amplified by selective ionic currents traversing the open channel pores. This miniaturization of computational gating allows the execution of over 1.2 zetta logical operations per second in the human cerebral cortex without combusting the brain by the released heat.

description: We report on a 100 ks Suzaku observation of the bright, nearby (z=0.008486) Seyfert 1.9 galaxy MCG -5-23-16. The broad-band (0.4-100 keV) X-ray spectrum allows us to determine the nature of the high energy emission with little ambiguity. The X-ray continuum consists of a cutoff power-law of photon index $Γ=1.9$, absorbed through Compton-thin matter of column density $N_{\rm H}=1.6\times10^{22}$ cm$^{-2}$. A soft excess is observed below 1 keV and is likely a combination of emission from scattered continuum photons and distant photoionized gas. The iron K line profile is complex, showing narrow neutral iron K$α$ and K$β$ emission, as well as a broad line which can be modeled by a moderately inclined accretion disk. The line profile shows either the disk is truncated at a few tens of gravitational radii, or the disk emissivity profile is relatively flat. A strong Compton reflection component is detected above 10 keV, which is best modeled by a combination of reflection off distant matter and the accretion disk. The reflection component does not appear to vary. The overall picture is that this Seyfert 1.9 galaxy is viewed at moderate (50 degrees) inclination through Compton-thin matter at the edge of a Compton-thick torus covering $2π$ steradians, consistent with unified models.

description: Millions of mosques around the world are suffering some problems such as ventilation and difficulty getting rid of bacteria, especially in rush hours where congestion in mosques leads to air pollution and spread of bacteria, in addition to unpleasant odors and to a state of discomfort during the pray times, where in most mosques there are no enough windows to ventilate the mosque well. This paper aims to solve these problems by building a model of smart mosques domes using weather features and outside temperatures. Machine learning algorithms such as k Nearest Neighbors and Decision Tree were applied to predict the state of the domes open or close. The experiments of this paper were applied on Prophet mosque in Saudi Arabia, which basically contains twenty seven manually moving domes. Both machine learning algorithms were tested and evaluated using different evaluation methods. After comparing the results for both algorithms, DT algorithm was achieved higher accuracy 98% comparing with 95% accuracy for kNN algorithm. Finally, the results of this study were promising and will be helpful for all mosques to use our proposed model for controlling domes automatically.

In the context of classical continuum systems, the Burgers vector is a measure of the deformation of the medium, and at a microscopic (atomic) scale, it is a naturally quantized object. One purpose of the present article is ultimately to probe an alternative way on how to quantize plane gravitational waves.

description: The helicity amplitudes $A^{p}_{1/2}$ and $S^{p}_{1/2}$ for the electromagnetic transition $γ^{*} N\to N^{*}(1535)$ are calculated in the quark model that is extended to include the lowest lying $qqqq\bar{q}$ components in addition to the $qqq$ component. It is found that with admixture of 5-quark components with a proportion of 20% in the nucleon and 25-65% in the $N^{*}(1535)$ resonance the calculated helicity amplitude $A^{p}_{1/2}$ decreases at the photon point, $Q^{2}=0$ to the empirical range. The $qqqq\bar{q}$ components contain $s\bar s$ pairs, which is consistent with the substantial width for $Nη$ decay of the $N^{*}(1535)$. The best description of the momentum dependence of the empirical helicity amplitudes is obtained by assuming that the $qqqq\bar{q}$ components are more compact than the $qqq$ component. However, this version of extended quark model still does not lead to a satisfactory simultaneous description of both $A^{p}_{1/2}$ and $S^{p}_{1/2}$ although with significant improvement.

description: Volumetric imaging of samples using fluorescence microscopy plays an important role in various fields including physical, medical and life sciences. Here we report a deep learning-based volumetric image inference framework that uses 2D images that are sparsely captured by a standard wide-field fluorescence microscope at arbitrary axial positions within the sample volume. Through a recurrent convolutional neural network, which we term as Recurrent-MZ, 2D fluorescence information from a few axial planes within the sample is explicitly incorporated to digitally reconstruct the sample volume over an extended depth-of-field. Using experiments on C. Elegans and nanobead samples, Recurrent-MZ is demonstrated to increase the depth-of-field of a 63x/1.4NA objective lens by approximately 50-fold, also providing a 30-fold reduction in the number of axial scans required to image the same sample volume. We further illustrated the generalization of this recurrent network for 3D imaging by showing its resilience to varying imaging conditions, including e.g., different sequences of input images, covering various axial permutations and unknown axial positioning errors. Recurrent-MZ demonstrates the first application of recurrent neural networks in microscopic image reconstruction and provides a flexible and rapid volumetric imaging framework, overcoming the limitations of current 3D scanning microscopy tools.

As a result of this, there is need to fortify the social network services in order to secure e-mail communication and reinforce data security. This paper advocates for an advanced and secured approach for improving communication in a social Network with the use of geo-location technique. The system was designed using an Object-Oriented software development methodology and implemented using the server-based scripting language - PHP, Cascading Style Sheets (CSS) and back-end with MySQL. The proposed system will help the government and security agencies fight recent security challenges in the country.

Human Centric Accessibility Graph For Environment Analysis

description: Understanding design decisions in relation to the future occupants of a building is a crucial part of good design. However, limitations in tools and expertise hinder meaningful human-centric decisions during the design process. In this paper, a novel Spatial Human Accessibility graph for Planning and Environment Analysis (SHAPE) is introduced that brings together the technical challenges of discrete representations of digital models, with human-based metrics for evaluating the environment. SHAPE: does not need labeled geometry as input, works with multi-level buildings, captures surface variations (e.g., slopes in a terrain), and can be used with existing graph theory (e.g., gravity, centrality) techniques. SHAPE uses ray-casting to perform a search, generating a dense graph of all accessible locations within the environment and storing the type of travel required in a graph (e.g., up a slope, down a step). The ability to simultaneously evaluate and plan paths from multiple human factors is shown to work on digital models across room, building, and topography scales. The results enable designers and planners to evaluate options of the built environment in new ways, and at higher fidelity, that will lead to more human-friendly and accessible environments.

description: Experimental information on the trilinear Higgs boson self-coupling $\kappa_3$ and the quartic self-coupling $\kappa_4$ will be crucial for gaining insight into the shape of the Higgs potential and the nature of the electroweak phase transition. While Higgs pair production processes provide access to $\kappa_3$, triple Higgs production processes, despite their small cross sections, will provide valuable complementary information on $\kappa_3$ and first experimental constraints on $\kappa_4$. We investigate triple Higgs boson production at the HL-LHC, employing efficient Graph Neural Network methodologies to maximise the statistical yield. We show that it will be possible to establish bounds on the variation of both couplings from the HL LHC analyses that significantly go beyond the constraints from perturbative unitarity. We also discuss the prospects for the analysis of triple Higgs production at future high-energy lepton colliders operating at the TeV scale.

description: High-harmonic generation is the cornerstone of nonlinear optics. It has been demonstrated in a wide range of crystalline systems including dielectrics, semiconductors, and semi-metals, as well as in gases, leaving metals out due to their low damage threshold. Here, we report on the high-harmonic generation in metallic titanium nitride (TiN) films. TiN is a refractory plasmonic metal, known for its high melting temperature and laser damage threshold, with optical properties similar to those of gold. We show that TiN can withstand laser pulses with peak intensities as high as 13 TW/cm$^2$, one order of magnitude higher than gold, enabling the emission of intraband harmonics up to photon energies of 11 eV. These harmonics can pave the way for compact and efficient plasmonic devices producing vacuum ultraviolet (VUV) frequency combs. Through numerical calculations and experimental studies, we show that the intensity scaling and angular anisotropy of the emitted VUV radiation stem from the anisotropic conduction band structure of TiN, thus confirming its intraband origin.
White dwarfs as test objects of Lorentz violations

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In the present work the thermodynamical properties of bosonic and fermionic gases are analyzed under the condition that a modified dispersion relation is present. This last condition implies a breakdown of Lorentz symmetry. The implications upon the condensation temperature will be studied, as well, as upon other thermodynamical variables such as specific heat, entropy, etc. Moreover, it will be argued that those cases entailing a violation of time reversal symmetry of the motion equations could lead to problems with the concept of entropy. Concerning the fermionic case it will be shown that Fermi temperature suffers a modification due to the breakdown of Lorentz symmetry. The results will be applied to white dwarfs and the consequences upon the Chandrasekhar mass--radius relation will be shown. The possibility of resorting to white dwarfs for the testing of modified dispersion relations is also addressed. It will be shown that the comparison of the current observations against the predictions of our model allows us to discard some values of one of the parameters appearing in the modifications of the dispersion relation.

Impacts of trade, environmental and agricultural policies in the North American hog/pork industry on water quality, trade patterns and welfare
Creators: name: Savard, Marielle
Publisher: name: University of British Columbia

description: The objectives of this study were: (1) to design a framework to measure the impact of trade, agricultural and environmental policies on water quality and (2) to assess trade patterns and market welfare (Marshallian measures of producer and consumer surpluses plus government payments) under various combinations of agricultural, environmental and trade policies. To reach those objectives, an environmental model, EPIC, was linked to a model of the North American hog/pork sector. Results show that trade liberalization does not contribute to water pollution in the two cases studies': Raleigh, North Carolina or Pont-Rouge Quebec. In fact, leaching, of nitrates decreases in Quebec following the elimination of countervailing duties, stabilization payments and the ban on US live hog exports to Canada. When nutrient management plans are implemented, both surface and groundwater quality increase. Environmental policies, including nutrient plans, also have a clear impact on trade patterns. The reduction in Quebec inventories triggers a decrease of Canadian live hog exports to the US and an increase of US pork exports to Canada. Trade and agricultural policy scenarios have a larger impact on trade patterns than on welfare and water quality. When the ban on US live hog exports to Canada is lifted, US live hog exports to Canada increase at the expense of US pork exports and Canadian live hog exports to the US. Market welfare impacts from trade policies are different from impacts induced by environmental policies. Trade policy scenarios trigger increases in North American market welfare while environmental policies are responsible for decreases in market welfare. Since trade liberalization has a positive impact on welfare, the welfare decrease from environmental policy is somewhat attenuated under free trade conditions.
Multi-hop Clock Synchronization in Wireless Ad-Hoc Networks

description: In this paper, we introduce Black Burst Clock Synchronization (BBCS), a novel protocol for multi-hop time synchronization in wireless ad-hoc  networks, located at MAC level. BBCS is based on the exchange of  synchronized tick and time frames, which are protected against collisions by a special encoding using black bursts. It provides a deterministic upper bound for clock offset that only depends on maximum network diameter, and on the used transceiver hardware. BBCS has low complexity in terms of communication, computation, storage, structure, and energy consumption. It provides low and deterministic convergence delay, and is robust against node movements and node failures. In this work, we introduce BBCS, provide a formal analysis of its properties, and evaluate the required  overhead for clock-synchronizing a multi-hop wireless ad-hoc network.

description: In this paper, we study a metamodel for the C++ programming language. We work out refactorings on the C++ metamodel and present the essentials as graph transformations. The refactorings are demonstrated in terms of the C++ source code and the C++ target code as well. Graph transformations allow to capture refactoring details on a conceptual and easy to understand, but also very precise level. Using this approach we managed to formalize two major aspects of refactorings: the structural changes and the preconditions.

An Approach to Invariant-based Program Refactoring
Creators: name: Massoni, Tiago
Publisher: name: European Association of Software Science and Technology
Year: 2007

description: Refactoring tools include checking of an object-oriented program for the
fulfillment of preconditions, for ensuring correctness. However, program invariants
â semantic information about classes and fields assumed valid during program execution
â are not considered by this precondition checking. As a result, applicability
of automated refactorings is constrained in these cases, as refactorings that would be
applicable considering the invariants get rejected, usually requiring manual changes.
In this paper, we describe initial work on the use of program invariants (declared as
code annotations) to increase applicability of automated refactoring. We propose an
approach that uses primitive program transformations that employ the invariant to
make the program syntactically amenable to the desired refactoring, before applying
the refactoring itself.

Optimizing Pattern Matching Compilation by Program Transformation
Creators: name: Balland, Emilie

Publisher: name: European Association of Software Science and Technology
Year: 2007

description: Motivated by the promotion of rewriting techniques and their use in major industrial applications, we have designed Tom: a pattern matching layer on top of conventional programming languages. The main originality is to support pattern matching against native data-structures like objects or records.

While crucial to the efficient implementation of functional languages
as well as rewrite rule based languages, in our case, this combination of algebraic constructs with arbitrary native data-structures makes the pattern matching algorithm more difficult to compile. In particular, well-known many-to-one automaton-based techniques cannot be used. We present a two-stages approach which first compiles pattern matching constructs in a naive way, and then optimize the resulting code by program transformation using rewriting. As a benefit, the compilation algorithm is simpler, easier to extend, and the resulting pattern matching code is almost as efficient as best known implementations.
