Comparative emergency powers: Brazil and the Philippines under COVID-19
Creators: name: Archegas, João Victor
Publisher: name: Católica Law Review
Year: 2021

description: During the 2020 coronavirus pandemic, a new debate emerged in the field of comparative constitutional studies as national governments responded to the health emergency in different (and at times opposite) ways. In this paper, I offer my contribution to this ongoing conversation with a comparative study of the legal bases of COVID-19 responses in Brazil and the Philippines. I selected both countries as case studies for three different reasons. First, they have similar institutional structures at the national level. Second, they have experienced a similar political history of democratization in the 80s. Third, both countries are now run by right-wing populist leaders. Nevertheless, while in the Philippines President Rodrigo Duterte took advantage of every single legal avenue available to monopolize the response to COVID-19 and aggrandize the national executive, in Brazil President Bolsonaro decided that his political interests would be better advanced through executive underreach. Relying on Hirschl’s ‘most similar cases logic’, I offer my take on why Brazil and the Philippines initially opted to travel down opposite paths and how they may converge somewhere down the road. In the first section of the paper, I introduce the reader to the use of emergency powers during the pandemic and explain the methodology of my study. Next, in the second section, I develop a theoretical analysis of comparative emergency powers based on a literature review. Then, in the third and fourth sections, I conduct an empirical analysis of the pandemic response by the national governments in Brazil and the Philippines and highlight some key distinctions between both countries. In the fifth section of the paper, contrary to a more traditional view, I argue that executive underreach may advance (and not restrain) populism. Finally, in the sixth section, I offer some concluding remarks.

description: The two-band model as introduced by Suhl, Matthias and Walker [Phys. Rev. Lett. 3, 551 (1959)] accounts for multiple energy bands in the vicinity of the Fermi energy which could contribute to electron pairing in superconducting systems. Here, extensions of this model are investigated wherein the effects of coupled superconducting order parameters with different symmetries and the presence of strong electron-lattice coupling on the superconducting transition temperature Tc are studied. Substantial enhancements of Tc are obtained from both effects.

description: Integration of commodity markets in developing countries has received considerable attention because price integration is perceived to be central to the success of food and agricultural policies. Price integration tests are performed in retail markets in Kinshasa (Zaire), i.e. between commodities, among retail markets, and between the wholesale and retail market level. Price transmission is measured by incorporating the co-integration concept into the classical long-run and shon-run market integration test. It is shown that although wholesale prices are input prices for retailers, they lack shon-run integration with retail prices. Differences exist between retail markets which do not reflect services or transponation costs. It is hypothesized that this is due to the existence ofsignificant transactions costs and deficiencies in information transmission.
X-Rays from Isolated Black Holes in the Milky Way

description: Galactic stellar-population-synthesis models, chemical-enrichment models, and long-duration Bulge microlensing events indicate about N_tot=(0.1-1) billion stellar-mass black holes reside in our Galaxy. We study X-ray emission from accretion from the interstellar medium on to isolated black holes. Although isolated black holes may be fewer in number than neutron stars, N_NS ~ 1 billion, their higher masses, ~9 M_sun, and smaller space velocities, v ~ 40 km/s, result in Bondi-Hoyle accretion rates ~4.E3 times higher than for neutron stars. We estimate that ~1.E4 N_9 isolated black holes within the Milky Way should accrete at > 1.E15 g/s, comparable to accretion rates inferred for black-hole X-ray binaries given a total number of black holes N_tot= N_9 1.E9. If black holes accrete at efficiencies only ~1.E-4(N_NS/N_tot)^0.8 of the neutron-star accretion efficiency, a comparable number of each may be detectable. We make predictions for the number of isolated accreting black holes in our Galaxy which can be detected with X-ray surveys as a function of efficiency, concluding that all-sky surveys at a depth of F = f 1.E-15 erg/cm^2/s/dex can find N(>F)~ 1.E4 N_9 (e5/f)^1.2 isolated accreting black holes for a velocity dispersion of 40 km/s and X-ray accretion efficiency = e5 1.E-5. Deeper surveys of the Galactic plane with Chandra and XMM-Newton may find tens of these objects per year, depending on the efficiency. We argue that a minimum mass can be derived for microlensing black-hole candidates if they are detected in the X-ray.

description: We develop a volume penalization method for inhomogeneous Neumann boundary conditions, generalizing the flux-based volume penalization method for homogeneous Neumann boundary condition proposed by Kadoch et al. [J. Comput. Phys. 231 (2012) 4365]. The generalized method allows us to model scalar flux through walls in geometries of complex shape using simple, e.g. Cartesian, domains for solving the governing equations. We examine the properties of the method, by considering a one-dimensional Poisson equation with different Neumann boundary conditions. The penalized Laplace operator is discretized by second order central finite-differences and interpolation. The discretization and penalization errors are thus assessed for several test problems. Convergence properties of the discretized operator and the solution of the penalized equation are analyzed. The generalized method is then applied to an advection-diffusion equation coupled with the Navier-Stokes equations in an annular domain which is immersed in a square domain. The application is verified by numerical simulation of steady free convection in a concentric annulus heated through the inner cylinder surface using an extended square domain.

description: The aim of this paper is to numerically investigate the orbital dynamics of the circular planar restricted problem of five bodies. By numerically integrating several large sets of initial conditions of orbits we classify them into three main categories: (i) bounded (regular or chaotic) (ii) escaping and (iii) close encounter orbits. In addition, we determine the influence of the mass parameter on the orbital structure of the system, on the degree of fractality, as well as on the families of symmetric and non-symmetric periodic orbits. The networks and the linear stability of both symmetric and non-symmetric periodic orbits are revealed, while the corresponding critical periodic solutions are also identified. The parametric evolution of the horizontal and the vertical linear stability of the periodic orbits is also monitored, as a function of the mass parameter.

Abstract:

The XENONnT experiment, which is the current phase of the XENON project, located at Laboratori Nazionali del Gran Sasso (Italy), aims to directly detect WIMP dark matter employing a dual-phase TPC with a 5.9 tonnes liquid xenon target. The first science run collected a total exposure of more than 1 tonne-year. The search for nuclear recoils induced by WIMPs, performed with a blind analysis, showed no significant excess and the ultra-low background achieved in XENONnT allowed the most sensitive searches for electronic recoils produced by solar axions and bosonic dark matter. The XENONnT experiment can also perform several neutrino searches besides dark matter, which will be illustrated. The neutrino magnetic moment, for which limits can be set, would enhance the elastic scattering of solar neutrinos with xenon electrons. Even without this enhancement, solar pp neutrinos could be observed via the ordinary elastic scattering off electrons. Solar neutrinos are expected to induce nuclear recoils through coherent elastic scattering off xenon nuclei. The detection of this process, never observed for solar neutrinos, would be possible for 8B neutrinos in XENONnT with increased exposure. In this way, supernova neutrinos can also be detected, resulting in a rise in the rate monitored by the triggerless data-acquisition system. Given the double-beta decaying 136Xe with 8.9% abundance in the target mass, the XENONnT detector is sensitive to the neutrinoless double-beta decay of this isotope. The expected sensitivity is not competitive with dedicated experiments but demonstrates the feasibility of this search in the next-generation LXe dark matter detectors.

description: We give a complete proof of the twisted duality property M(q)'= Z M(q^\perp) Z* of the (self-dual) CAR-Algebra in any Fock representation. The proof is based on the natural Halmos decomposition of the (reference) Hilbert space when two suitable closed subspaces have been distinguished. We use modular theory and techniques developed by Kato concerning pairs of projections in some essential steps of the proof. As a byproduct of the proof we obtain an explicit and simple formula for the graph of the modular operator. This formula can be also applied to fermionic free nets, hence giving a formula of the modular operator for any double cone.

description: Neutron spectroscopy has revealed a highly unusual magnetic structure and dynamics in YVO$_3$, an insulating pseudocubic perovskite that undergoes a series of temperature induced phase transitions between states with different spin and orbital ordering patterns. A good description of the neutron data is obtained by a theoretical analysis of the spin and orbital correlations of a realistic one-dimensional model. This leads to the tentative identification of one of the phases of YVO$_3$ with the ``orbital Peierls state'', a theoretically proposed many-body state comprised of orbital singlet bonds.

description: We present optical and/or near-IR images of 128 ultra steep spectrum (USS) radio sources. Roughly half of the objects are identified in the optical images (R 94% are detected at K5). The major axes of the identifications in K-band are preferentially oriented along the radio axes, with half of them having compact morphologies. The 22 sources with spectroscopic redshifts and K-band magnitudes follow the K-z relation found from previous radio samples, but with a larger scatter. We argue that this may be due to a dependence of K-magnitude on the radio power, with the highest radio power sources inhabiting the most massive host galaxies. We present a composite K-z diagram of radio-loud and radio-quiet galaxies, selected from the HDF-North and the Hawaii surveys. Out to z ~ 1, the radio-loud galaxies are >~ 2 magnitudes brighter. We argue that this is not due to a contribution from the AGN or emission lines. This difference strongly suggests that radio galaxies pinpoint the most massive systems out to the highest known redshifts, probably due to the mutual correlation of the mass of the galaxy and the radio power on the mass of the central black hole.

description: In 1986, Matveev defined the notion of Borromean surgery for closed oriented 3-manifolds and showed that the equivalence relation generated by this move is characterized by the pair (first betti number, linking form up to isomorphism). We explain how this extends for 3-manifolds with spin structure if we replace the linking form by the quadratic form defined by the spin structure. We then show that the equivalence relation among closed spin 3-manifolds generated by spin Borromean surgeries is characterized by the triple (first betti number, linking form up to isomorphism, Rochlin invariant modulo 8).

description: Hysteresis is a major feature of the solid-liquid transition in granular materials. This property, by allowing metastable states, can potentially yield catastrophic phenomena such as earthquakes or aerial landslides. The origin of hysteresis in granular flows is still debated. However, most mechanisms put forward so far rely on the presence of inertia at the particle level. In this paper, we study the avalanche dynamics of non-Brownian suspensions in slowly rotating drums and reveal large hysteresis of the avalanche angle even in the absence of inertia. By using micro-silica particles whose interparticle friction coefficient can be turned off, we show that microscopic friction, conversely to inertia, is key to triggering hysteresis in granular suspensions. To understand this link between friction and hysteresis, we use the rotating drum as a rheometer to extract the suspension rheology close to the flow onset for both frictional and frictionless suspensions. This analysis shows that the flow rule for frictionless particles is monotonous and follows a power law of exponent $α\!= \! 0.37 \pm 0.05$, in close agreement with the previous theoretical prediction, $α\!=\! 0.35$. By contrast, the flow rule for frictional particles suggests a velocity-weakening behavior, thereby explaining the flow instability and the emergence of hysteresis. These findings show that hysteresis can also occur in particulate media without inertia, questioning the intimate nature of this phenomenon. By highlighting the role of microscopic friction, our results may be of interest in the geophysical context to understand the failure mechanism at the origin of undersea landslides.

The dependence of the Curie temperature on the thickness of the film, the surface interaction and the transverse field were investigated. It is assumed that the long-range interaction decays with the distance between the pseudo-spins as a power law. The dependence of the Curie temperature and the critical transverse field on the long-range exponent are obtained.

description: Systems involving Partial Differential Equations (PDEs) have recently become more popular among the machine learning community. However prior methods usually treat infinite dimensional problems in finite dimensions with Reduced Order Models. This leads to committing to specific approximation schemes and subsequent derivation of control laws. Additionally, prior work does not consider spatio-temporal descriptions of noise that realistically represent the stochastic nature of physical systems. In this paper we suggest a new reinforcement learning framework that is mostly model-free for Stochastic PDEs with additive spacetime noise, based on variational optimization in infinite dimensions. In addition, our algorithm incorporates sparse representations that allow for efficient learning of feedback policies in high dimensions. We demonstrate the efficacy of the proposed approach with several simulated experiments on a variety of SPDEs.

description: Photoacoustic computed tomography (PACT), also known as optoacoustic tomography, is an emerging imaging technique that holds great promise for biomedical imaging. PACT is a hybrid imaging method that can exploit the strong endogenous contrast of optical methods along with the high spatial resolution of ultrasound methods. In its canonical form that is addressed in this article, PACT seeks to estimate the photoacoustically-induced initial pressure distribution within the object. Image reconstruction methods are employed to solve the acoustic inverse problem associated with the image formation process. When an idealized imaging scenario is considered, analytic solutions to the PACT inverse problem are available; however, in practice, numerous challenges exist that are more readily addressed within an optimization-based, or iterative, image reconstruction framework. In this article, the PACT image reconstruction problem is reviewed within the context of modern optimization-based image reconstruction methodologies. Imaging models that relate the measured photoacoustic wavefields to the sought-after object function are described in their continuous and discrete forms. The basic principles of optimization-based image reconstruction from discrete PACT measurement data are presented, which includes a review of methods for modeling the PACT measurement system response and other important physical factors. Non-conventional formulations of the PACT image reconstruction problem, in which acoustic parameters of the medium are concurrently estimated along with the PACT image, are also introduced and reviewed.

description: We apply the Coherent Potential Approximation (CPA) to a simple extended Hubbard model with a nearest and next nearest neighbour hopping for disordered superconductors with s-, d- and p-wave pairing. We show how the Van Hove singularities in the electron density of states enhance the transition temperature Tc for exotic superconductors in a clean and weakly disordered system. The Anderson theorem and pair-breaking effects in presence of Van Hove singularity caused by non-magnetic disorder are also discussed.

Pion-induced production of hidden-charm pentaquarks $P_{c}(4312),P_{c}(4440)$, and $P_{c}(4457)$

description: The production of the hidden-charm pentaquarks $P_{c}$ via pion-induced reaction on a proton target is investigated within an effective Lagrangian approach. Three experimentally observed states, $P_c(4312)$, $P_c(4440)$, and $P_c(4457)$, are considered in the calculation, and the Reggeized $t$-channel meson exchange is considered as main background for the reaction $π^{-}p\rightarrow J/ψn$. The numerical results show that the experimental data of the total cross section of the reaction $π^{-}p\rightarrow J/ψn$ at $W\simeq 5$ GeV can be well explained by contribution of the Reggeized $t$ channel with reasonable cutoff. If the branching ratios $Br[P_{c}\rightarrow J/ψN]\simeq 3\%$ and $Br[P_{c}\rightarrow πN]\simeq 0.05\%$ are taken, the average value of the cross section from the $P_{c}(4312)$ contribution is about 1.2 nb/100 MeV, which is consistent with existing rude data at near-threshold energies. The results indicate that the branching ratios of the $P_{c}$ states to the $J/ψN$ and $πN$ should be small. The shape of differential cross sections shows that the Reggeized $t$-channel provides a sharp increase at extreme forward angles, while the differential cross sections from the $P_{c}$ states contributions are relatively flat. High-precision experimental measurements on the reaction $π^{-}p\rightarrow J/ψn$ at near-threshold energies are suggested to confirm the LHCb hidden-charm pentaquarks as genuine states, and such experiments are also helpful to understand the origin of these resonance structures.

description: The complex impedance of a semiconductor superlattice biased into the regime of negative differential conductivity and driven by an additional GHz ac voltage is computed. From a simulation of the nonlinear spatio-temporal dynamics of traveling field domains we obtain strong variations of the amplitude and phase of the impedance with increasing driving frequency. These serve as fingerprints of the underlying quasiperiodic or frequency locking behavior. An anomalous phase shift appears as a result of phase synchronization of the traveling domains. If the imaginary part of the impedance is compensated by an external inductor, both the frequency and the intensity of the oscillations strongly increase.

description: The long-standing debate on the existence of ancient oceans on Mars has been recently revived by evidence for tsunami resurfacing events that date from the Late Hesperian geological era. It has been argued that these tsunami events originated from the impact of large meteorites on a deglaciated or nearly deglaciated ocean present in the northern hemisphere of Mars. Here we show that the presence of such a late ocean faces a paradox. If cold, the ocean should have been entirely frozen shortly after its formation, thus preventing the formation of tsunami events. If warm, the ice-free ocean should have produced fluvial erosion of Hesperian Mars terrains much more extensively than previously reported. To solve this apparent paradox, we suggest a list of possible tests and scenarios that could help to reconcile constraints from climate models with tsunami hypothesis. These scenarios could be tested in future dedicated studies.
