description: We report on the results of a broad band (0.1-100 keV) spectral analysis of the bursting atoll source MXB 1728-34 observed by the BeppoSAX satellite. Three bursts were present during this observation. The spectrum during the bursts can be fitted by a blackbody with a temperature of 2 keV. From the bursts we also estimate a distance to the source of 5.1 kpc. MXB 1728-34 was in a rather soft state during the BeppoSAX observation. The persistent spectrum is well fitted by a continuum consisting of a soft blackbody emission and a comptonized spectrum. We interpreted the soft component as the emission from the accretion disk. Taking into account a spectral hardening factor of 1.7, we estimated that the inner disk radius is $R_{\rm in} \sqrt{\cos i} \sim 20$ km, where i is the inclination angle. The comptonized component could originate in a spherical corona, with temperature of 10 keV and optical depth of 5, surrounding the neutron star. A broad gaussian emission line at 6.7 keV is observed in the spectrum, probably emitted in the ionized corona or in the inner part of the disk. Another emission line is present at 1.66 keV.

description: Faraday rotation and synchrotron emission from extragalactic radio sources give evidence for the presence of magnetic fields extending over ~Mpc scales. However, the origin of these fields remains elusive. With new high-resolution grid simulations we studied the growth of magnetic fields in a massive galaxy cluster that in several aspects is similar to the Coma cluster. We investigated models in which magnetic fields originate from primordial seed fields with comoving strengths of 0.1 nG at redshift z=30. The simulations show evidence of significant magnetic field amplification. At the best spatial resolution (3.95 kpc), we are able to resolve the scale where magnetic tension balances the bending of magnetic lines by turbulence. This allows us to observe the final growth stage of the small-scale dynamo. To our knowledge this is the first time that this is seen in cosmological simulations of the intracluster medium. Our mock observations of Faraday Rotation provide a good match to observations of the Coma cluster. However, the distribution of magnetic fields shows strong departures from a simple Maxwellian distribution, suggesting that the three-dimensional structure of magnetic fields in real clusters may be significantly different than what is usually assumed when inferring magnetic field values from rotation measure observations.

description: We derive exact expressions for the local entanglement entropy E in the ground state of the one-dimensional Hubbard model at a quantum phase transition driven by a change in magnetic field h or chemical potential u. The leading divergences of dE/dh and dE/du are shown to be directly related to those of the zero-temperature spin and charge susceptibilities. Logarithmic corrections to scaling signal a change in the number of local states accessible to the system as it undergoes the transition.

description: The signatures of planets hosted by M dwarfs are more readily detected with transit photometry and radial velocity methods than those of planets around larger stars. Recently, transit photometry was used to discover seven planets orbiting the late-M dwarf TRAPPIST-1. Three of TRAPPIST-1's planets fall in the Habitable Zone, a region where liquid water could exist on the planetary surface given appropriate planetary conditions. We aim to investigate the habitability of the TRAPPIST-1 planets by studying the star's activity and its effect on the planets. We analyze previously-published space- and ground-based light curves and show the photometrically-determined rotation period of TRAPPIST-1 appears to vary over time due to complicated, evolving surface activity. The dramatic changes of the surface of TRAPPIST-1 suggest that rotation periods determined photometrically may not be reliable for this and similarly active stars. While the activity of the star is low, we use the premise of the "cosmic shoreline" to provide evidence that the TRAPPIST-1 environment has potentially led to the erosion of possible planetary atmospheres by extreme ultraviolet stellar emission.

description: Large-scale text datasets have long eluded a family of particularly elegant and effective clustering methods that exploits the power of pair-wise similarities between data points due to the prohibitive cost, time- and space-wise, in operating on a similarity matrix, where the state-of-the-art is at best quadratic in time and in space. We present an extremely fast and simple method also using the power of all pair-wise similarity between data points, and show through experiments that it does as well as previous methods in clustering accuracy, and it does so with in linear time and space, without sampling data points or sparsifying the similarity matrix.

description: Within a dynamical model, rescattering effects are studied in coherent pion photoproduction on the deuteron in the $Δ$(1232) resonance region. The model consists of a system of coupled equations for the N$Δ$, NN$π$ and NN channels. Pion rescattering leads in general to a significant reduction of total and differential cross sections resulting in a better description of experimental data. Only a few polarization observables are sensitive to rescattering effects. In particular $T_{20}$ allows an analysis of the reaction mechanism for specific kinematics. The question how rescattering affects the sensitivity to the E2 excitation of the $Δ$ resonance is also studied.

description: Parametric coupling of lower hybrid pump wave with low frequency collisionless/weakly collisional trapped electron drift wave, with frequency lower than the electron bounce frequency is studied. The coupling produces two lower hybrid sidebands. The sidebands beat with the pump to exert a low frequency ponderomotive force on electrons that causes a frequency shift in the drift wave, leading to the growth of the latter. The short wavelength modes are destabilized and they enhance the anomalous diffusion coefficient.

A través de un enfoque histórico y comparativo, el documento identifica las normas e instrumentos de política que se han adoptado en las últimas décadas y su impacto en los flujos de IED y en la economía del país en general. Concluye que las políticas de atracción de IED han sido adoptadas al garete, sin propósitos claros de desarrollo alineados con un interés nacional, y por ende sus efectos han sido poco concluyentes, con impacto tanto positivo como negativo. Finalmente, y con base en recomendaciones de organizaciones internacionales y derecho comparado, se sugieren lineamientos para la adopción de una política pública de atracción de IED sostenible y cimentada sobre una visión clara de país.
description: This text seeks to analyze the evolution of foreign direct investment (FDI) attraction policies in Colombia between 2002 and 2023, evaluating their effectiveness and impact. Through a historical and comparative approach, the document identifies the regulations and policy instruments that have been adopted in the past couple of decades and their impact on FDI flows and the country's economy. It concludes that FDI attraction policies have been adopted haphazardly, without clear development purposes aligned with a national interest, and therefore their effects have been inconclusive, with both positive and negative impacts. Finally, based on recommendations from international organizations and comparative law, the author suggests guidelines for the adoption of a sustainable FDI attraction public policy grounded in a clear country purpose.

description: We address the current crucial issues on the formation and evolution of cluster galaxies: ie., connection between the Butcher-Oemler effect, assembly of cluster galaxies, truncation of star formation, and the origin of S0 galaxies. We construct the field corrected colour-magnitude (CM) diagrams for 7 CNOC clusters (0.23M*+1). Truncation of star formation is, however, found to be relatively milder (with a time scale of 1 Gyr) than suggested by the viorent processes such as ram-pressure stripping and/or mergers/harassment. The BO effect is after all found to be a combination of three effects, namely, increasing field star formation activity, increasing galaxy infall rate, and the truncatin of star formation after the accretion. Our approach naturally leads to the history of galaxy assembly and `global' star foramtion for `cluster' galaxies.

description: El riesgo de enfermedad laboral salvo algunas excepciones se materializa con ocasión de exposiciones a factores ocupacionales por períodos de mediana a larga duración. Durante este período de exposición hay una importante probabilidad de que la cobertura de los riesgos sea el resultado de la suma de tiempos de afiliación a través de distintas administradoras de riesgos laborales. Son todas estas administradoras las llamadas a participar en la cobertura del riesgo. La ley ha reconocido esta situación jurídica particular y previsto el derecho a reembolso a favor de la administradora a la que corresponde garantizar tal cobertura al afiliado, sin embargo no se ha previsto un mecanismo para ello. Se propone en el trabajo de investigación un modelo para resolver las controversias en torno a los factores para hacer efectivo el reembolso, sin necesidad de acudir a mecanismos judiciales.

The law has recognized this particular legal situation and provided for the right to reimbursement in favor of the administrator responsible for guaranteeing such coverage to the member; however, no mechanism has been provided for this. In the research work, a model is proposed to resolve controversies regarding the factors to make reimbursement effective, without the need to resort to judicial mechanisms.

description: To stay alive, most people with kidney failure need a plastic tube (catheter) inserted into a large vein in their neck so their blood can be regularly cleaned through a haemodialysis machine. Using numerous large, high-quality datasets, we found that infections and blockages related to haemodialysis catheters were a big problem in Australia. Both complications may be prevented by improving the quality and consistency of catheter care. Conversely, use of step tip catheters, prophylactic antibiotics before insertion and a more invasive approach to replacing malfunctioning catheters may be detrimental. The findings will improve the safety of haemodialysis therapy worldwide.

Morita equivalence is used to map the computation of loop correlators onto the combinatorics of non-planar graphs. Several nonperturbative examples of symmetry breaking under area-preserving diffeomorphisms are thereby presented. Analytic expressions for correlators of Wilson loops with infinite winding number are also derived and shown to agree with results from ordinary Yang-Mills theory.

A Spectral Learning Approach to Range-Only SLAM

description: We present a novel spectral learning algorithm for simultaneous localization and mapping (SLAM) from range data with known correspondences. This algorithm is an instance of a general spectral system identifi- cation framework, from which it inherits several desirable properties, including statistical consistency and no local optima. Compared with popular batch optimization or multiple-hypothesis tracking (MHT) methods for range-only SLAM, our spectral approach o↵ers guaranteed low computational requirements and good tracking performance. Compared with MHT and with popular extended Kalman filter (EKF) or extended information filter (EIF) approaches, our approach does not need to linearize a transition or measurement model. We provide a theoretical analysis of our method, including finite-sample error bounds. Finally, we demonstrate on a real-world robotic SLAM problem that our algorithm is not only theoretically justified, but works well in practice: in a comparison of multiple methods, the lowest errors come from a combination of our algorithm with batch optimization, but our method alone produces nearly as good a result at far lower computational cost.

description: The properties of microwave circuits and optical structures can be described in terms of their scattering matrix which is extracted from the orthogonal decomposition of the electric field. We discretize the Maxwell' equations with ortogonal grids using the Finite Integration Technique (FIT). Maxwellian grid equations are formulated for staggered nonequidistant rectangular grids and for tetrahedral nets with corresponding dual Voronoi cells. The surface of the computation domain is assumed to be an electric or magnetic wall, open-region problems require uniaxial Perfectly Matched Layer (PML) absorbing boundary conditions. Calculating the excitations at the ports, one obtains eigenvalue problems and then large-scale systems of linear algebraic equations. This paper is a revised version of the preprint no. 987.

description: Gravity darkening induced by rapid stellar rotation provides us with a unique opportunity to characterize the spin-orbit misalignment of a planetary system through analysis of its photometric transit. We use the gravity-darkened transit modeling code simuTrans to reproduce the transit light curve of Kepler-13Ab by separately analyzing phase-folded transits for 12 short-cadence Kepler quarters. We verify the temporal change in impact parameter indicative of spin-orbit precession identified by Szabó et al. (2012) and Masuda (2015), reporting a rate of change $db/dt = (-4.1 \pm 0.2) \times 10^{-5}$ day$^{-1}$. We further investigate the effect of light dilution on the fitted impact parameter and find that less than 1% of additional light is sufficient to explain the seasonal variation seen in the Kepler quarter data. We then extend our precession analysis to the phase curve data from which we report a rate of change $db/dt = (-3.2 \pm 1.3) \times 10^{-5}$ day$^{-1}$. This value is consistent with that of the transit data at a lower significance and provides the first evidence of spin-orbit precession based solely on the temporal variation of the secondary eclipse.

description: We use molecular dynamics computer simulations to investigate the local motion of the particles in a supercooled simple liquid. Using the concept of the distance matrix we find that the alpha-relaxation corresponds to a small number of crossings from one meta-basin to a neighboring one. Each crossing is very rapid and involves the collective motion of O(40) particles that form a relatively compact cluster, whereas string-like motions seem not to be relevant for these transitions. These compact clusters are thus candidates for the cooperatively rearranging regions proposed long times ago by Adam and Gibbs.

Meson-exchange Model for $πN$ scattering and $γN -> πN$ reaction

description: An effective Hamiltonian consisting of bare $Δ\leftrightarrowπN$, $γN$ vertex interactions and energy-independent meson-exchange $πN \leftrightarrow πN, γN$ transition operators is derived by applying a unitary transformation to a model Lagrangian with $N,Δ,π$, $ρ$, $ω$, and $γ$ fields. With appropraite phenomenological form factors and coupling constants for $ρ$ and $Δ$, the model can give a good description of $πN$ scattering phase shifts up to the $Δ$ excitation energy region. It is shown that the best reproduction of the recent LEGS data of the photon-asymmetry ratios in $γp \rightarrow π^0 p$ reactions provides rather restricted constraints on the coupling strengths $G_E$ of the electric $E2$ and $G_M$ of the magnetic $M1$ transitions of the bare $Δ\leftrightarrow γN$ vertex and the less well-determined coupling constant $g_{ωNN}$ of $ω$ meson. Within the ranges that $G_M = 1.9 \pm 0.05$, $G_E = 0.0 \pm 0.025$, and $7 \leq g_{ωNN}\leq 10.5$, the predicted differential cross sections and photon-asymmetry ratios are in an overall good agreement with the data of $γp \rightarrow π^0 p$, $γp \rightarrow π^+ n$, and $γn\rightarrow π^- p$ reactions from 180 MeV to the $Δ$ excitation region. The predicted $M_{1^+}$ and $E_{1^+}$ multipole amplitudes are also in good agreement with the empirical values determined by the amplitude analyses. The constructed effective Hamiltonian is free of the nucleon renormlization problem and hence is suitable for nuclear many-body calculations. We have also shown that the assumptions made in the $K$-matrix method, commonly used in extracting empirically the $γN \rightarrow Δ$ transition amplitudes from the data, are consistent with

description: We present multiwavelength observations of the newly discovered X-ray transient XTE J1118+480 obtained in the rising phase of the 2000 April outburst. This source is located at unusually high Galactic latitude and in a very low absorption line of sight. This made the first EUVE spectroscopy of an X-ray transient outburst possible. Together with our HST, RXTE, and UKIRT data this gives unprecedented spectral coverage. We find the source in the low hard state. The flat IR-UV spectrum appears to be a combination of optically thick disk emission and flat spectrum emission, possibly synchrotron, while at higher energies, including EUV, a typical low hard state power-law is seen. EUVE observations reveal no periodic modulation, suggesting an inclination low enough that no obscuration by the disk rim occurs. We discuss the nature of the source and this outburst and conclude that it may be more akin to mini-outbursts seen in GRO J0422+32 than to a normal X-ray transient outburst.

It is shown that Israel's junction conditions across the brane restrict severely the dependence of the matter fields on the spacetime coordinates. As examples, a scalar field or a Yang-Mills potential can be only either time-dependent or radial-coordinate dependent for the chosen gauge, while for a perfect fluid it must be co-moving.

description: The surface decoration layers of Samantabhadra Bodhisattva and Thousand Hand Guanyin from Dazu Rock Carvings were examined using digital microscopy, energy-dispersive spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and pyrolysis—gas chromatography/mass spectrometry using thermally assisted hydrolysis and methylation. Gypsum was present in the preparation layer, while the painted layer included lacquer sap (urushiol). The presence of heat-bodied tung oil and resin (benzoin resin) was also detected in some painted layers. Mineral pigments were found in the painted layers, including cinnabar, lead red, orpiment, litharge, and carbon. In addition, there was a layer of gold foil on the surface of the Thousand Hand Guanyin sample. The mass percentage of gold was 96.70%. The gold foil contained gold, silver, copper, and iron as a solid solution. This study provides a reference for the study and protection of cultural relic samples from grottoes.

description: The use of psychedelic drugs as treatments for mental illness and addiction is receiving increasing scientific and public attention. This thesis explores the social dynamics influencing psychedelic medicine in Australia, through the perspectives of the research community. The findings illustrate that psychedelic medicine has engaged the interests of diverse groups, and been shaped by historical controversies and contemporary international progress. For many in the research community, psychedelic medicine represented an opportunity to usher in a more holistic view of mental health, but there were also pragmatic and systematic barriers to achieving its potentials.

description: Latent variable models are powerful tools for probabilistic modeling, and have been successfully applied to various domains, such as speech analysis and bioinformatics. However, parameter learning algorithms for latent variable models have predominantly relied on local search heuristics such as expectation maximization (EM). We propose a fast, local-minimum-free spectral algorithm for learning latent variable models with arbitrary tree topologies, and show that the joint distribution of the observed variables can be reconstructed from the marginals of triples of observed variables irrespective of the maximum degree of the tree. We demonstrate the performance of our spectral algorithm on synthetic and real datasets; for large training sizes, our algorithm performs comparable to or better than EM while being orders of magnitude faster.

 Pemphigus fraxini Hartig, 1841: 367. SYNTYPES: 7 (408 [4.08]; field no. missing [4.09-4.14]), Fraxinus.
 Prociphilus fraxini (Hartig, 1841) (change of combination—Börner, 1952: 193, in contradiction to secondary homonymy and synonymy with Pemphigus fraxini (Geoffroy, 1762) and Pemphigus fraxini (Fabricius, 1777) identified on p. 291: “fraxini Aphis Geoffr. 1762 p.[494] (= F. 1776 p. [303], Htg. 1841 p. 367)”).
 Prociphilu s fraxini (Fabricius, 1777) (senior secondary homonym and synonym— Eastop & Hille Ris Lambers, 1976: 57, “ A. fraxini Geoffroy, 1762 invalid”; Eastop & Hille Ris Lambers, 1976: 342). Valid
 Specimens. Seven alates with wax covered abdomens mounted on separate pins. The only specimen with a corresponding journal entry (408) was collected from the leaves and stems of ash [Fraxinus] on June 28, 1837.
 Remarks. The name was first published as Pemphigus fraxini in Hartig (1839), but was not accompanied by a description, definition or an indication and therefore is not available. In Börner (1952), the name is treated in combination with the genus Prociphilus and as a homonym and synonym of both Aphis fraxini Geoffroy, 1762 (nomen nudum) and Aphis fraxini [= Prociphilus fraxini] Fabricius, 1777. Confirmation of this synonymy is needed as Prociphilus bumeliae (Schrank, 1801) also occurs on Fraxinus in Europe and is similar in morphology.

description: The two-dimensional electron gas occurring between the band insulators SrTiO$_3$ and LaAlO$_3$ continues to attract considerable interest, due to the possibility of dynamic control over the carrier density, and the ensuing phenomena such as magnetism and superconductivity. The formation of this conducting interface is sensitive to the growth conditions, but despite numerous investigations, there are still questions about the details of the physics involved. In particular, not much is known about the electronic structure of the growing LaAlO$_3$ layer at the growth temperature (around 800 $^o$C) in oxygen (pressure around $5\times 10^{-5}$ mbar), since analysis techniques at these conditions are not readily available. We developed a pulsed laser deposition system inside a low-energy electron microscope in order to study this issue. The setup allows for layer-by-layer growth control and in-situ measurements of the angle-dependent electron reflection intensity, which can be used as a fingerprint of the electronic structure of the surface layers during growth. By using different substrate terminations and growth conditions we observe two families of reflectivity maps, which we can connect either to samples with an AlO$_2$-rich surface and a conducting interface; or to samples with a LaO-rich surface and an insulating interface. Our observations emphasize that substrate termination and stoichiometry determine the electronic structure of the growing layer, and thereby the conductance of the interface.

Discovery of X-ray Emission from G328.4+0.2, a Crab-Like Supernova Remnant

description: G328.4+0.2 is a moderately small (5 arcmin x 5arcmin) Galactic radio supernova remnant (SNR) at a distance of at least 17 kpc that has been long suggested to be Crab-like. Here we report on the detection with ASCA of the X-ray emission from the SNR. The X-ray source is faint with an observed flux of (6.0 +/- 0.8)E-13 erg/s/cm^2 over the 2-10 keV band. The emission is heavily cut-off at low energies and no flux is detected below 2 keV. Spectral analysis confirms that the column density to the source is indeed large, N_H ~ 1E23 atoms/cm^2, and consistent with the total column density of hydrogen through the Galaxy at this position. Good fits to the spectrum can be obtained for either thermal plasma or nonthermal power-law models, although the lack of detected line emission as well as other evidence argues against the former interpretation. The power-law index we find, α_P = 2.9 (+0.9,-0.8), is consistent with other Crab-like SNRs. In the radio band G328.4+0.2 is nearly as luminous as the Crab Nebula, yet in the X-ray band luminosity it is some 70 times fainter. Nevertheless its inferred soft X-ray band luminosity is greater than all but the brightest pulsar-powered synchrotron nebulae and implies that G328.4+0.2 contains a rapidly spinning, as yet undetected, pulsar that is losing energy at a rate of approximately 1E38 erg/s.

Theoretical phase diagram for the room temperature Electron-Hole Liquid in photo-excited quasi-2D monolayer MoS$_2$

description: Strong correlations between electrons and holes can drive the existence of an electron-hole liquid (EHL) state, typically at high carrier densities and low temperatures. The recent emergence of quasi-2D monolayer transition metal dichalcogenides (TMDCs) provide ideal systems to explore the EHL state since ineffective screening of the out of plane field lines in these quasi-2D systems allows for stronger charge carrier correlations in contrast to conventional 3D bulk semiconductors and enabling the existence of the EHL at high temperatures. Here we construct the phase diagram for the photo-induced first-order phase transition from a plasma of electron-hole pairs to a correlated EHL state in suspended monolayer MoS2. We show that quasi-2D nature of monolayer TMDCs and the ineffective screening of the out of plane field lines allow for this phase transition to occur at and above room temperature, thereby opening avenues for studying many-body phenomena without the constraint of cryogenics.

description: The dynamics of confined glassforming liquids is discussed on the basis of the recent extension of the mode coupling theory for the liquid-glass transition to the model of the quenched-annealed binary mixture. It is in particular shown that, in confinement, the density correlation functions always decay to a non-zero infinite time value, even in the fluid state, and some clarification is given about the question of the relation between structure and dynamics in confined fluids.
