description: First and foremost, we show that a 4-dimensional conformally flat generalized Ricci recurrent spacetime $(GR)_4$ is an Einstein manifold. We examine such a spacetime as a solution of $f(R, G)$-gravity theory and it is shown that the additional terms from the modification of the gravitational sector can be expressed as a perfect fluid. Several energy conditions are investigated with $f(R, G) = R +\sqrt{G}$ and $f(R, G) = R^2+GlnG$. For both the models, weak, null and dominant energy conditions are satisfied while strong energy condition is violated, which is a good agreement with the recent observational studies which reveals that the current universe is in accelerating phase.

description: A revolução das Histórias em Quadrinhos (HQs) começou com a produção digital, onde HQs são criadas com ferramentas digitais; então surgiu a difusão digital, onde quadrinhos são distribuídos de forma digital; por fim, histórias digitais, referente à evolução dos quadrinhos no ambiente digital (MCCLOUD, 2005). Assim, artistas digitais encontraram nas HQtrônicas, histórias produzidas para plataformas digitais, como atender melhor os anseios dos leitores digitais: interatividade, animação, diagramação dinâmica, trilha/ efeitos sonoros, tela infinita/ narrativa multilinear (FRANCO, 2013). Para dimensionar o tamanho desse formato digital, somente a plataforma Webtoon tinha 72 milhões de usuários ativos em 2021, 14 milhões só nos EUA, segundo a Revista Forbes (2022). Neste artigo, propõe-se uma análise de obras publicadas nos últimos anos, observando as singularidades das HQtrônicas, e comprovando-se intransferíveis para papel. Para isso, toma-se por base teórica autores como: Eisner (2001), Franco (2011; 2013), McCloud (2004; 2005), Rosa (2014).

Low-degree modes

subject: FOS: Physical sciences

description: The quest of the knowledge of the structure and dynamics of the solar interior has been possible thanks to the study of the resonant acoustic (p) modes that are trapped in the solar interior. Since the solar rotation lifts the azimuthal degeneracy of the resonant modes, their eigenfrequencies are split into their m-components; where l is the angular degree, n the radial order, and, m the azimuthal order. This separation --usually called rotational splitting (or just splitting)-- depends on the rotation rate in the region sampled by the mode. In the same way, the precise frequency of a mode depends on the physical properties of the cavity where the mode propagates. Using inversion techniques the rotation rate, the sound speed or the density profile at different locations inside the Sun can be inferred from a suitable lineal combination of the measured modes. But, during the last year, a particular effort has been done in the extraction of physical information directly from the combination of frequencies: the large and the small frequency separations.

description: Quantum target detection is an emerging application that utilizes entanglement to enhance the sensing of the presence of an object. Although several experimental demonstrations for certain situations have been reported recently, the single-shot detection limit imposed by the Helstrom limit has not been reached because of the unknown optimum measurements. Here we report an experimental demonstration of quantum target detection, also known as quantum illumination, in the single-photon limit. In our experiment, one photon of the maximally entangled photon pair is employed as the probe signal and the corresponding optimum measurement is implemented at the receiver. We explore the detection problem in different regions of the parameter space and verify that the quantum advantage exists even in a forbidden region of the conventional illumination, where all classical schemes become useless. Our results indicate that quantum illumination breaks the classical limit for up to 40%, while approaching the quantum limit imposed by the Helstrom limit. These results not only demonstrate the advantage of quantum illumination, but also manifest its valuable potential of target detection.

Bohmian Mechanics at Space-Time Singularities. II. Spacelike Singularities

description: We develop an extension of Bohmian mechanics by defining Bohm-like trajectories for quantum particles in a curved background space-time containing a spacelike singularity. As an example of such a metric we use the Schwarzschild metric, which contains two spacelike singularities, one in the past and one in the future. Since the particle world lines are everywhere timelike or lightlike, particles can be annihilated but not created at a future spacelike singularity, and created but not annihilated at a past spacelike singularity. It is argued that in the presence of future (past) spacelike singularities, there is a unique natural Bohm-like evolution law directed to the future (past). This law differs from the one in non-singular space-times mainly in two ways: it involves Fock space since the particle number is not conserved, and the wave function is replaced by a density matrix. In particular, we determine the evolution equation for the density matrix, a pure-to-mixed evolution equation of a quasi-Lindblad form. We have to leave open whether a curvature cut-off needs to be introduced for this equation to be well defined.

Scattering of low energy neutrinos and antineutrinos by atomic electrons

description: Studies of neutrino mixing and oscillations, solar neutrinos as background in dark matter searches involving electron detection, detection of sterile neutrino warm dark matter, and of possible electromagnetic properties of neutrinos, have generated interest in the low energy O(10 keV) scattering of electron neutrinos and antineutrinos by atomic electrons where the binding of the atomic electron cannot be ignored. Of particular interest is the ionization of atoms by neutrinos and antineutrinos. Most existing calculations are based on modifications of the free electron differential cross section, which destroy the relationship between the neutrino helicities and the orbital and spin angular momenta of the atomic electrons. The present calculations maintain the full collision dynamics by formulating the scattering in configuration space using the Bound Interaction Picture, rather than the usual formulation in the Interaction Picture in momentum space as appropriate to scattering by free electrons. Energy spectra of ionization electrons produced by scattering of neutrinos and antineutrinos with energies of 5, 10, 20, and 30 keV by hydrogen, helium and neon have been calculated using Dirac central field eigenfunctions and are presented as ratios to the spectra for scattering by free electrons. Binding effects increase strongly with atomic number, are largest for low neutrino energy and, for each neutrino energy, greatest at the high electron energy end of the spectrum. The most extreme effects of binding are for 5 keV scattering by Ne where the ratios are less than 0.1. The energy spectra are calculated for both a Coulombic final electron state and a free final electron state. The results indicate that the binding effects from the continuum state of the final electron are significant and can be comparable to those arising from the bound initial electron state.

description: Experiments on dewetting thin polymer films confirm the theoretical prediction that thermal noise can strongly influence characteristic time-scales of fluid flow and cause coarsening of typical length scales. Comparing the experiments with deterministic simulations, we show that the Navier-Stokes equation has to be extended by a conserved bulk noise term to accomplish the observed spectrum of capillary waves. Due to thermal fluctuations the spectrum changes from an exponential to a power law decay for large wavevectors. Also the time evolution of the typical wavevector of unstable perturbations exhibits noise induced coarsening that is absent in deterministic hydrodynamic flow.

Non-local interactions in hydrodynamic turbulence at high Reynolds numbers: the slow emergence of scaling laws

description: We analyze the data stemming from a forced incompressible hydrodynamic simulation on a grid of 2048^3 regularly spaced points, with a Taylor Reynolds number of Re~1300. The forcing is given by the Taylor-Green flow, which shares similarities with the flow in several laboratory experiments, and the computation is run for ten turnover times in the turbulent steady state. At this Reynolds number the anisotropic large scale flow pattern, the inertial range, the bottleneck, and the dissipative range are clearly visible, thus providing a good test case for the study of turbulence as it appears in nature. Triadic interactions, the locality of energy fluxes, and structure functions of the velocity increments are computed. A comparison with runs at lower Reynolds numbers is performed, and shows the emergence of scaling laws for the relative amplitude of local and non-local interactions in spectral space. The scalings of the Kolmogorov constant, and of skewness and flatness of velocity increments, performed as well and are consistent with previous experimental results. Furthermore, the accumulation of energy in the small-scales associated with the bottleneck seems to occur on a span of wavenumbers that is independent of the Reynolds number, possibly ruling out an inertial range explanation for it. Finally, intermittency exponents seem to depart from standard models at high Re, leaving the interpretation of intermittency an open problem.

Stresses and vibrations in bandsaw blades
Creators: name: Eschler, Andreas
Publisher: name: University of British Columbia
Year: 2010

description: Due to rising lumber costs it has become more and more important to optimize the cutting performance of bandsaws as they are used in the forest products industry. One important aim is to reduce the lateral and torsional deflections of the blade to minimize the thickness of the cut. This study tries to assess the influence of various typical bandsaw parameters on the stress distribution in the bandsaw blade and on the vibrational behaviour of the stationary and the running sawblade. Experiments were performed with a fullsize industrial production bandsaw. The experimental results for the stress-strain measurements of the stationary sawblade are compared with results from theoretical solutions. Vibration measurements of the stationary and of the running blade are compared to values derived from MOTE'S [9] flexible band solution and KANAUCHI'S solution [21] for lateral deflection and with ALSPAUGH'S [2] solution for torsional vibrations. The results presented show that the static stress measurements agree very well with the analytically predicted results. Major factors influencing the stress distribution in the blade: the axial prestress, stresses due to bending of the blade over the bandsaw wheels, and stresses due to tilting of the top bandsaw wheel were examined. A comparison of the experimental and analytical results of the vibration measurements for the stationary sawblade showed very good agreement for the lateral natural frequencies, while the torsional natural frequencies were considerably higher than the analytically predicted values. Similar results could be observed for the natural frequencies of the running blade. The mode shapes of the stationary sawblade at the natural frequencies were measured. It was found that the modeshapes consisted of coupled modes for most tiltstress differences.

description: Superconducting qubits behave as artificial two-level atoms and are used to investigate fundamental quantum phenomena. In this context, the study of multi-photon excitations occupies a central role. Moreover, coupling superconducting qubits to on-chip microwave resonators has given rise to the field of circuit QED. In contrast to quantum-optical cavity QED, circuit QED offers the tunability inherent to solid-state circuits. In this work, we report on the observation of key signatures of a two-photon driven Jaynes-Cummings model, which unveils the upconversion dynamics of a superconducting flux qubit coupled to an on-chip resonator. Our experiment and theoretical analysis show clear evidence for the coexistence of one- and two-photon driven level anticrossings of the qubit-resonator system. This results from the symmetry breaking of the system Hamiltonian, when parity becomes a not well-defined property. Our study provides deep insight into the interplay of multiphoton processes and symmetries in a qubit-resonator system.

description: Kepler's supernova remnant (SNR) which is produced by the most recent naked-eye supernova in our Galaxy is one of the best studied SNRs, but its gamma-ray detection has eluded us so far. Observations with modern imaging atmospheric Cherenkov telescopes (IACT) have enlarged the knowledge about nearby SNRs with ages younger than 500 years by establishing Cassiopeia A and Tycho's SNRs as very high energy (VHE) gamma-ray sources and setting a lower limit on the distance to Kepler's SNR. This SNR is significantly more distant than the other two and expected to be one of the faintest gamma-ray sources within reach of the IACT arrays of this generation. We report strong evidence for a VHE signal from Kepler's SNR based on deep observations of the High Energy Stereoscopic System (H.E.S.S.) with an exposure of 152 hours, including 122 hours accumulated in 2017-2020. We further discuss implications of this result for cosmic-ray acceleration in young SNRs.

description: In inflationary cosmological models driven by an inflaton field the origin of the primordial inhomogeneities which are responsible for large scale structure formation are the quantum fluctuations of the inflaton field. These are usually computed using the standard theory of cosmological perturbations, where both the gravitational and the inflaton fields are linearly perturbed and quantized. The correlation functions for the primordial metric fluctuations and their power spectrum are then computed. Here we introduce an alternative procedure for computing the metric correlations based on the Einstein-Langevin equation which emerges in the framework of stochastic semiclassical gravity. We show that the correlation functions for the metric perturbations that follow from the Einstein-Langevin formalism coincide with those obtained with the usual quantization procedures when the scalar field perturbations are linearized. This method is explicitly applied to a simple model of chaotic inflation consisting of a Robertson-Walker background, which undergoes a quasi-de-Sitter expansion, minimally coupled to a free massive quantum scalar field. The technique based on the Einstein-Langevin equation can, however, deal naturally with the perturbations of the scalar field even beyond the linear approximation, as is actually required in inflationary models which are not driven by an inflaton field such as Starobinsky's trace-anomaly driven inflation or when calculating corrections due to non-linear quantum effects in the usual inflaton driven models.

We present a catalogue of 73,221 white dwarf candidates extracted from the astrometric and photometric data of the recently published Gaia-DR2 catalogue. White dwarfs were selected from the Gaia Hertzsprung-Russell diagram with the aid of the most updated population synthesis simulator.

Our analysis shows that Gaia has virtually identified all white dwarfs within 100 pc from the Sun. Hence; our sub-population of 8555 white dwarfs within this distance limit and the colour range considered; -0.52<(GBP-GRP)<0.80; is the largest and most complete volume-limited sample of such objects to date. From this sub-sample; we identified 8,343 CO-core and 212 ONe-core white dwarf candidates and derived a white dwarf space density of 4.9± 0.4 x 10-3 pc-3. A bifurcation in the Hertzsprung-Russell diagram for these sources; which our models do not predict; is clearly visible.

We used the Virtual Observatory SED Analyzer tool to derive effective temperatures and luminosities for our sources by fitting their spectral energy distributions; that we built from the ultraviolet to the near-infrared using publicly available photometry through the Virtual Observatory. From these parameters; we derived the white dwarf radii. Interpolating the radii and effective temperatures in hydrogen-rich white dwarf cooling sequences; we derived the surface gravities and masses.

The Gaia 100 pc white dwarf population is clearly dominated by cool (~8,000 K) objects and reveals a significant population of massive (M~0.8 Solar Mass) white dwarfs; of which no more than 30-40 per cent can be attributed to hydrogen-deficient atmospheres; and whose origin remains uncertain.

semiology of reality

description: The essay intends to explore the relationship between image and reality in Pasolini's thought starting from a comparison with other theoretical proposals that influenced him, in particular, those of André Bazin and Roland Barthes. For these French critics, as for the Italian filmmaker, the cinematographic image has the capacity to reveal the expressive nature of reality, that is, its irreducibility to a conventional code and meaning. The revelation of the expressive nature of reality occurs in the cinematic work through a process that Pasolini calls “transubstantiation” and that is part of his "philosophy of cinema". Starting from Appunti per un'Orestiade africana (Notes for an African Orestiad), the essay aims to illustrate the mechanism of semantic transubstantiation and its function of semiological highlighting of the expressive nature of reality. This operation, which can be traced back to what Pasolini calls a "semiology of reality", pursues a political aim, which, following Deleuze, we can define as an attempt not so much to represent reality as to restore the possibility of believing in reality.

description: We present a set of three-dimensional (3D) direct numerical simulations of incompressible decaying magnetohydrodynamic turbulence in which we investigate the influence of an external uniform magnetic field B_0. A parametric study in terms of B_0 intensity is made where, in particular, we distinguish the shear- from the pseudo-Alfven waves dynamics. The initial kinetic and magnetic energies are equal with a negligible cross-correlation. Both the temporal and spectral effects of B_0 are discussed. A sub-critical balance is found between the Alfven and nonlinear times with both a global and a spectral definition. The nonlinear dynamics of strongly magnetized flows is characterized by a different k_perp-spectrum (where B_0 defines the parallel direction) if it is plotted at a fixed k_// (2D spectrum) or if it is integrated (averaged) over all k_// (1D spectrum). In the former case a much wider inertial range is found with a steep power law, closer to the wave turbulence prediction than the Kolmogorov one like in the latter case. It is believed that the averaging effect may be a source of difficulty to detect the transition towards wave turbulence in natural plasmas. For the first time, the formation of filaments is reported within current and vorticity sheets in strongly magnetized flows which modifies our classical picture of dissipative sheets in conductive flows.

description: The algebraic structure of V.P. Potapov's Fundamental Matrix Inequality (FMI) is discussed and its interpolation meaning is analyzed. Functional model spaces are involved. A general Abstract Interpolation Problem is formulated which seems to cover all the classical and recent problems in the field and the solution set of this problem is described using the Arov--Grossman formula. The extension theory of isometric operators is the proper language for treating interpolation problems of this type.

description: The variational principle of the Onsager-Machlup integral is used to describe the stochastic dynamics of a micromachine, such as an enzyme, characterized by odd elasticity. The obtained most probable path is found to become non-reciprocal in the presence of odd elasticity and is further related to the entropy production.
Evidence of a higher nodal band $α$+$^{44}$Ca cluster state in fusion reactions and $α$ clustering in $^{48}$Ti

description: In the nucleus $^{48}$Ti, whose structure is essential in evaluating the half-life of the neutrinoless double-$β$ decay ($0νββ$) of $^{48}$Ca, the existence of the $α$ cluster structure is shown for the first time. A unified description of scattering and structure is performed for the $α$+$^{44}$Ca system. By using a global potential, which reproduces experimental $α$+$^{44}$Ca scattering over a wide range of incident energies, $E_α$=18 - 100 MeV, it is shown that the observed $α$+$^{44}$Ca fusion excitation function at $E_α$=9 -18 MeV is described well. The bump at $E_α$=10.2 MeV is found to be due to a resonance which is a $7^-$ state of the higher nodal band with the $α$+$^{44}$Ca cluster structure in $^{48}$Ti. The local potential $α$+$^{44}$Ca cluster model locates the ground band of $^{48}$Ti in agreement with experiment and reproduces the enhanced $B(E2)$ values in the ground band well. This shows that collectivity due to $α$ clustering in $^{48}$Ti should be taken into account in the evaluation of the nuclear matrix element in the $0νββ$ double-$β$ decay of $^{48}$Ca.

description: The charge ordering transition induced by the nearest-neighbor Coulomb repulsion, V, in the 1/4-filled extended Hubbard model is investigated using Cellular Dynamical Mean-Field Theory. We find a transition to a strongly renormalized charge ordered Fermi liquid at VCO and a metal-to-insulator transition at VMI>VCO. Short range antiferromagnetism occurs concomitanly with the CO transition. Approaching the charge ordered insulator the Fermi surface deforms and the scattering rate of electrons develops momentum dependence on the Fermi surface.

Remarks. When alive, the mesial faces of the palms and carpi of the chelipeds were conspicuously reflective, a character that faded upon preservation. Reflective surfaces may function for communication, as has also been reported in deep-water portunoid crabs in the genus Ovalipes (Parker et al. 1998). Color patterns otherwise fit closely with South African specimens of D. jacquesi, described by Landschoff (2018). Dardanus jacquesi is very similar to D. dearmatus, but can be differentiated from the latter on the basis of several characters, particularly in the slenderness of the propodus of the left third pereopod (Asakura & Hirayama 2002). On the basis of this character, and in the stoutness of the chelipeds, the Marianas specimens better agree with D. jacquesi. However, the pleonal plates were not visible in the present female specimens, and the spination on the inner face of the left cheliped is less pronounced than in the type material as described by Asakura & Hirayama (2002).

description: The connection between halo gas acquisition through the circumgalactic medium (CGM) and galaxy star formation has long been studied. In this series of two papers, we put this interplay within the context of the galaxy environment on large scales (several hundreds of kpc), which, to a certain degree, maps out various paths for galaxy interactions. We use the IllustrisTNG-100 simulation to demonstrate that the large-scale environment modulates the circumgalactic gas angular momentum, resulting in either enhanced (Paper I) or suppressed (Paper II) star formation inside a galaxy. In this paper (Paper I), we show that the large-scale environment around a star-forming galaxy is often responsible for triggering new episodes of star formation. Such an episodic star formation pattern is well synced with a pulsating motion of the circumgalactic gas, which, on the one hand receives angular momentum modulations from the large-scale environment, yielding in-spiralling gas to fuel the star-forming reservoir, while, on the other hand, is affected by the feedback activities from the galaxy centre. As a result, a present-day star-forming galaxy may have gone through several cycles of star-forming and quiescent phases during its evolutionary history, with the circumgalactic gas carrying out a synchronized cadence of "breathing in and out" motions out to $\sim 100$ kpc.

Speeding up Simplification of Polygonal Curves using Nested Approximations

Publisher: name: arXiv
Year: 2007
Subjects: subject: Computational Geometry (cs.CG)

description: We develop a multiresolution approach to the problem of polygonal curve approximation. We show theoretically and experimentally that, if the simplification algorithm A used between any two successive levels of resolution satisfies some conditions, the multiresolution algorithm MR will have a complexity lower than the complexity of A. In particular, we show that if A has a O(N2/K) complexity (the complexity of a reduced search dynamic solution approach), where N and K are respectively the initial and the final number of segments, the complexity of MR is in O(N).We experimentally compare the outcomes of MR with those of the optimal "full search" dynamic programming solution and of classical merge and split approaches. The experimental evaluations confirm the theoretical derivations and show that the proposed approach evaluated on 2D coastal maps either shows a lower complexity or provides polygonal approximations closer to the initial curves.

Dynamical symmetries in noncommutative theories

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In the present work we study dynamical space-time symmetries in noncommutative relativistic theories by using the minimal canonical extension of the Doplicher, Fredenhagen and Roberts algebra. Our formalism is constructed in an extended space-time with independent degrees of freedom associated with the object of noncommutativity $θ^{μν}$. In this framework we consider theories that are invariant under the Poincaré group ${\cal P}$ or under its extension ${\cal P}'$, when translations in the extra dimensions are permitted. The Noether's formalism adapted to such extended $x+θ$ space-time is employed.

AI4IA Conference Report 2022
Creators: UNESCO Information For All Programme (IFAP)
Publisher: name: University of Alberta Library
Year: 2022

The UNESCO Information for All Programme (IFAP) Working Group on Information Accessibility (WGIA) hosted its third conference on September 28, 2022. The conference focused on a wide range of issues, including but not limited to, Artificial Intelligent and law, ethics, disability, creativity and innovation, accessibility and responsible AI for the betterment of the planet. The conference was primarily organised under the auspices of the UNESCO Cluster Office for the Caribbean, Kingston, Jamaica and the UNESCO Regional Office for Southern Africa, Harare, Zimbabwe. A bunch of organisations across the world came together in collaboration to achieve the success of this one-day conference, namely the Kule Institute for Advanced Studies (KIAS) and AI for Society (AI4S), both at University of Alberta, Canada, the Centre for New Economic Diplomacy (CNED) in ORF, India and the Broadcasting Commission of Jamaica.

The conference was held in commemoration of the International Day for Universal Access to Information (IDUAI) as proclaimed by the UN General Assembly, marked on the 28th September of each year. IDUAI was recognised internationally in order to bring in multiple stakeholders from across the world, to build an interdisciplinary discourse around issues of access to information. The conference followed this vision by delving deep into the conversations on all things AI and Information Accessibility, through the lenses of public policies, international issues, human creativity and art, and everyday ethical problems arising from the rapid growth in AI structures globally.

The conference had five main themes:

Delivery, Access and Usability

Positive Planet: Can AI be leveraged in a responsible and responsive manner to better our relationship with our planet?

Overcoming Divides

Intersection of AI, Art and Human Creativity

Ethical Digital Transformation
