description: We classify the supersymmetric solutions of minimal $N=2$ gauged supergravity in four dimensions with neutral signature. They are distinguished according to the sign of the cosmological constant and whether the vector field constructed as a bilinear of the Killing spinor is null or non-null. In neutral signature the bilinear vector field can be spacelike, which is a new feature not arising in Lorentzian signature. In the $Λ<0$ non-null case, the canonical form of the metric is described by a fibration over a three-dimensional base space that has $\text{U}(1)$ holonomy with torsion. We find that a generalized monopole equation determines the twist of the bilinear Killing field, which is reminiscent of an Einstein-Weyl structure. If, moreover, the electromagnetic field strength is self-dual, one gets the Kleinian signature analogue of the Przanowski-Tod class of metrics, namely a pseudo-hermitian spacetime determined by solutions of the continuous Toda equation, conformal to a scalar-flat pseudo-Kähler manifold, and admitting in addition a charged conformal Killing spinor. In the $Λ<0$ null case, the supersymmetric solutions define an integrable null Kähler structure. In the $Λ>0$ non-null case, the manifold is a fibration over a Lorentzian Gauduchon-Tod base space. Finally, in the $Λ>0$ null class, the metric is contained in the Kundt family, and it turns out that the holonomy is reduced to ${\rm Sim}(1)\times{\rm Sim}(1)$. There appear no self-dual solutions in the null class for either sign of the cosmological constant.

description: We perform molecular dynamics (MD) simulations of the crystallization process in binary Lennard-Jones systems during heating and cooling to investigate atomic-scale crystallization kinetics in glass-forming materials. For the cooling protocol, we prepared equilibrated liquids above the liquidus temperature $T_l$ and cooled each sample to zero temperature at rate $R_c$. For the heating protocol, we first cooled equilibrated liquids to zero temperature at rate $R_p$ and then heated the samples to temperature $T > T_l$ at rate $R_h$. We measured the critical heating and cooling rates $R_h^*$ and $R_c^*$, below which the systems begin to form a substantial fraction of crystalline clusters during the heating and cooling protocols. We show that $R_h^* > R_c^*$, and that the asymmetry ratio $R_h^*/R_c^*$ includes an intrinsic contribution that increases with the glass-forming ability (GFA) of the system and a preparation-rate dependent contribution that increases strongly as $R_p \rightarrow R_c^*$ from above. We also show that the predictions from classical nucleation theory (CNT) can qualitatively describe the dependence of the asymmetry ratio on the GFA and preparation rate $R_p$ from the MD simulations and results for the asymmetry ratio measured in Zr- and Au-based bulk metallic glasses (BMG). This work emphasizes the need for and benefits of an improved understanding of crystallization processes in BMGs and other glass-forming systems.

Candidate gene length polymorphisms are linked to dispersive behaviour: Searching for a mechanism behind the "paradox of the great speciators"
Creators: name: Estandia, Andrea
Publisher: name: Zenodo
Year: 2023

description: The "paradox of the great speciators" has puzzled evolutionary biologists for over half a century. A great speciator requires excellent dispersal ability to explain its occurrence on multiple islands but reduced dispersal ability to explain its high number of subspecies. A rapid reduction in dispersal ability is often invoked to solve this apparent paradox, but a proximate mechanism has not been identified. Here, we explore the role of six genes linked to migration and animal personality differences (CREB1, CLOCK, ADCYAP1, NPAS2, DRD4, and SERT) in 20 South Pacific populations of silvereye (Zosterops lateralis) that range from highly sedentary to partially migratory to determine if genetic variation is associated with dispersal propensity. We detected genetic associations in three of the six genes: i) in a partial migrant population, migrant individuals had longer microsatellite alleles at the CLOCK gene compared to resident individuals from the same population; ii) CREB1 displayed longer average microsatellite allele lengths in recently colonised island populations (< 200 years), compared to evolutionarily older populations. Bayesian broken stick regression models supported a reduction in CREB1 length with time since colonisation and decreasing dispersal propensity; and iii) like CREB1, DRD4 showed differences in polymorphisms between recent and old colonisations but a further sample size is needed to confirm. ADCYAP1, SERT, and NPAS2 were variable but that variation was not associated with dispersal propensity. The association of genetic variants at three genes with migration and dispersal ability in silvereyes provides the impetus for further exploration of genetic mechanisms underlying dispersal shifts, and the prospect of resolving a long-running evolutionary paradox through a genetic lens.

description: We present new limits on an isotropic stochastic gravitational-wave background (GWB) using a six pulsar dataset spanning 18 yr of observations from the 2015 European Pulsar Timing Array data release. Performing a Bayesian analysis, we fit simultaneously for the intrinsic noise parameters for each pulsar, along with common correlated signals including clock, and Solar System ephemeris errors, obtaining a robust 95$\%$ upper limit on the dimensionless strain amplitude $A$ of the background of $A<3.0\times 10^{-15}$ at a reference frequency of $1\mathrm{yr^{-1}}$ and a spectral index of $13/3$, corresponding to a background from inspiralling super-massive black hole binaries, constraining the GW energy density to $Ω_\mathrm{gw}(f)h^2 < 1.1\times10^{-9}$ at 2.8 nHz. We also present limits on the correlated power spectrum at a series of discrete frequencies, and show that our sensitivity to a fiducial isotropic GWB is highest at a frequency of $\sim 5\times10^{-9}$~Hz. Finally we discuss the implications of our analysis for the astrophysics of supermassive black hole binaries, and present 95$\%$ upper limits on the string tension, $Gμ/c^2$, characterising a background produced by a cosmic string network for a set of possible scenarios, and for a stochastic relic GWB. For a Nambu-Goto field theory cosmic string network, we set a limit $Gμ/c^2<1.3\times10^{-7}$, identical to that set by the {\it Planck} Collaboration, when combining {\it Planck} and high-$\ell$ Cosmic Microwave Background data from other experiments. For a stochastic relic background we set a limit of $Ω^\mathrm{relic}_\mathrm{gw}(f)h^2<1.2 \times10^{-9}$, a factor of 9 improvement over the most stringent limits previously set by a pulsar timing array.

As perdas mais significativas são de suas camadas decorativas, portanto as cerâmicas possuem potencial de reaproveitamento. A pesquisa tem por objetivo eliminar processos de deterioração das cerâmicas de azulejos históricos, por meio de tratamento térmico, para reutilização na produção de réplicas. A amostragem consiste em azulejos, inteiros ou fragmentos, com perdas de vidrado maiores que 50%. Os métodos utilizados foram: documentação e mapeamento de danos; caracterização física das amostras antes e depois da requeima (ensaios de densidade, absorção total em água, colorimetria, e microscopia óptica); aplicação de procedimentos restaurativos com limpeza por via mecânica e química, e requeima a temperatura de 1000°C. No mapeamento de danos foram identificados sujidades, depósitos, e manchas escuras, brancas, ou avermelhadas. A limpeza foi eficaz na remoção de vestígios de vidrado, sujidades, depósitos de tinta e de argamassa, e biocolonização superficiais. As manchas enegrecidas, brancas e/ou avermelhadas foram removidas ou suavizadas após o tratamento térmico. A requeima, auxiliou no clareamento da cor das chacotas e maior uniformidade das superfícies. Foi observado um pequeno aumento na porosidade acessível das amostras. Os resultados preliminares apontam que o reaproveitamento das cerâmicas de azulejos descartados é um caminho sustentável a ser seguido na conservação e restauro da azulejaria.

description: We generalize the technique of fringe-rate filtering, whereby visibilities measured by a radio interferometer are re-weighted according to their temporal variation. As the Earth rotates, radio sources traverse through an interferometer's fringe pattern at rates that depend on their position on the sky. Capitalizing on this geometric interpretation of fringe rates, we employ time-domain convolution kernels to enact fringe-rate filters that sculpt the effective primary beam of antennas in an interferometer. As we show, beam sculpting through fringe-rate filtering can be used to optimize measurements for a variety of applications, including mapmaking, minimizing polarization leakage, suppressing instrumental systematics, and enhancing the sensitivity of power-spectrum measurements. We show that fringe-rate filtering arises naturally in minimum variance treatments of many of these problems, enabling optimal visibility-based approaches to analyses of interferometric data that avoid systematics potentially introduced by traditional approaches such as imaging. Our techniques have recently been demonstrated in Ali et al. (2015), where new upper limits were placed on the 21 cm power spectrum from reionization, showcasing the ability of fringe-rate filtering to successfully boost sensitivity and reduce the impact of systematics in deep observations.

Here, we study numerically the effect of inductive circuits on the dynamics of this fluid-solid-electric system and on its energy harvesting efficiency. In particular, a destabilization of the system is identified leading to energy harvesting at lower flow velocities. Also, a frequency lock-in between the flag and the circuit is shown to significantly enhance the system's harvesting efficiency. These results suggest promising efficiency enhancements of such flow energy harvesters through the output circuit optimization.

description: We study historical dynamics of joint equilibrium distribution of stock returns in the U.S. stock market using the Boltzmann distribution model being parametrized by external fields and pairwise couplings. Within Boltzmann learning framework for statistical inference, we analyze historical behavior of the parameters inferred using exact and approximate learning algorithms. Since the model and inference methods require use of binary variables, effect of this mapping of continuous returns to the discrete domain is studied. The presented analysis shows that binarization preserves market correlation structure. Properties of distributions of external fields and couplings as well as industry sector clustering structure are studied for different historical dates and moving window sizes. We found that a heavy positive tail in the distribution of couplings is responsible for the sparse market clustering structure. We also show that discrepancies between the model parameters might be used as a precursor of financial instabilities.

description: A method for realizing asymmetric (one-way) transmission of discretized light in modulated, linear and purely passive optical lattices is suggested, which exploits the idea of unidirectional coherent perfect absorption. The system consists of a linear photonic lattice of coupled resonators or waveguides, side coupled to a chain of lossy elements, in which light can avoid the occupation of the dissipative sites when propagating in one way, but not in the opposite one. Non-reciprocity requires modulation of the resonator/waveguide parameters, realizing a dissipative optical Aharonov-Bohm diode with non-reciprocal behavior.

description: Blandford-Znajek (BZ) mechanism describes a process extracting rotation energy from a spinning black hole (BH) via magnetic field lines penetrating the event horizon of central BH. In this paper, we present a perturbation approach to study force-free jets launched by the BZ mechanism, and its two immediate applications: (1) we present a high-order split monopole perturbation solution to the BZ mechanism, which accurately pins down the energy extraction rate $\dot E$ and well describes the structure of BH magnetosphere for all range of BH spins ($0\leq a\leq 1$); (2) the approach yields an exact constraint for the monopole field configuration in the Kerr spacetime, $I = Ω(1-A_ϕ^2)$, where $A_ϕ$ is the $ϕ-$component of the vector potential of electromagnetic field, $Ω$ is the angular velocity of magnetic field lines and $I$ is the poloidal electric current. The constraint is of particular importance to benchmark the accuracy of numerical simulations.

description: We propose a general framework for reconstructing transform-sparse images from undersampled (squared)-magnitude data corrupted with outliers. This framework is implemented using a multi-layered approach, combining multiple initializations (to address the nonconvexity of the phase retrieval problem), repeated minimization of a convex majorizer (surrogate for a nonconvex objective function), and iterative optimization using the alternating directions method of multipliers. Exploiting the generality of this framework, we investigate using a Laplace measurement noise model better adapted to outliers present in the data than the conventional Gaussian noise model. Using simulations, we explore the sensitivity of the method to both the regularization and penalty parameters. We include 1D Monte Carlo and 2D image reconstruction comparisons with alternative phase retrieval algorithms. The results suggest the proposed method, with the Laplace noise model, both increases the likelihood of correct support recovery and reduces the mean squared error from measurements containing outliers. We also describe exciting extensions made possible by the generality of the proposed framework, including regularization using analysis-form sparsity priors that are incompatible with many existing approaches.

Subjects: The lactate threshold, The ventilatory threshold, The anaerobic threshold.

description: For decades, many studies have addressed the notion of threshold in sports training given its importance inoptimizing of the effort. However, the terminology varies depending on the method of measurement andthe method of determining this threshold. There are several notions such as the aerobic and anaerobicthreshold, the lactate threshold 1 and 2, the ventilatory threshold 1 and 2, and in this respect, different authors have reported many contradictions, and many received ideas, often erroneous, were conveyed to sports actors.In this article, we present an analysis of the contradictory results of several previous studies on the notion of threshold.

Stimulated photon emission and two-photon Raman scattering in a coupled-cavity QED system

description: We study the scattering problem of photon and polariton in a one-dimensional coupled-cavity system. Analytical approximate analysis and numerical simulation show that a photon can stimulate the photon emission from a polariton through polariton-photon collisions. This observation opens the possibility of photon-stimulated transition from insulating to radiative phase in a coupled-cavity QED system. Inversely, we also find that a polariton can be generated by a two-photon Raman scattering process. This paves the way towards single photon storage by the aid of atom-cavity interaction.

description:  

Azulejos históricos são de grande importância cultural no cenário luso-brasileiro, no qual se destaca a cidade de Belém-PA, pela grande variedade de exemplares. Apesar da sua importância patrimonial, painéis azulejados da cidade apresentam elevado estágio de deterioração e são descartados como entulho. As perdas mais significativas são de suas camadas decorativas, portanto as cerâmicas possuem potencial de reaproveitamento. A pesquisa tem por objetivo eliminar processos de deterioração das cerâmicas de azulejos históricos, por meio de tratamento térmico, para reutilização na produção de réplicas. A amostragem consiste em azulejos, inteiros ou fragmentos, com perdas de vidrado maiores que 50%. Os métodos utilizados foram: documentação e mapeamento de danos; caracterização física das amostras antes e depois da requeima (ensaios de densidade, absorção total em água, colorimetria, e microscopia óptica); aplicação de procedimentos restaurativos com limpeza por via mecânica e química, e requeima a temperatura de 1000°C. No mapeamento de danos foram identificados sujidades, depósitos, e manchas escuras, brancas, ou avermelhadas. A limpeza foi eficaz na remoção de vestígios de vidrado, sujidades, depósitos de tinta e de argamassa, e biocolonização superficiais. As manchas enegrecidas, brancas e/ou avermelhadas foram removidas ou suavizadas após o tratamento térmico. A requeima, auxiliou no clareamento da cor das chacotas e maior uniformidade das superfícies. Foi observado um pequeno aumento na porosidade acessível das amostras. Os resultados preliminares apontam que o reaproveitamento das cerâmicas de azulejos descartados é um caminho sustentável a ser seguido na conservação e restauro da azulejaria.

description: Chaos provides many interesting properties that can be used to achieve computational tasks. Such properties are sensitivity to initial conditions, space filling, control and synchronization. Chaotic neural models have been devised to exploit such properties. In this paper, a chaotic spiking neuron model is investigated experimentally. This investigation is performed to understand the dynamic behaviours of the model. The aim of this research is to investigate the dynamics of the nonlinear dynamic state neuron (NDS) experimentally. The experimental approach has revealed some quantitative and qualitative properties of the NDS model such as the control mechanism, the reset mechanism, and the way the model may exhibit dynamic behaviours in phase space. It is shown experimentally in this paper that both the reset mechanism and the self-feed back control mechanism are important for the NDS model to work and to stabilise to one of the large number of available unstable periodic orbits (UPOs) that are embedded in its attractor. The experimental investigation suggests that the internal dynamics of the NDS neuron provide a rich set of dynamic behaviours that can be controlled and stabilised. These wide range of dynamic behaviours may be exploited to carry out information processing tasks.
Development of an innovative process for combined nitrogen oxide and dust separation using catalytically active additives at a wood-fired power plant

description: Pollutants which are emitted during the combustion of wood are NOx, CO, CO2, SO2, VOCs and particulate matter (PM) to name just a few [2]. Some of the main environmental impacts such as photochemical smog and acid rain as well as impact on human health are caused by NOx [3,4]. One way to reduce the emissions of NOx is the selective catalytic reduction (SCR). These catalysts are installed in a high dust, a low dust or a tails end configuration [5]. In this project named DeNOx-DePM, the catalyst will be added directly to the flue gas to create a catalytically active filter cake and after deactivation the catalyst can be removed together with the fine dust at a mesh filter.
