description: Objetivos generales: * Promover la reflexión y el análisis crítico sobre el derecho penal, la política criminal y especialmente sobre la pena de prisión como castigo. Para esto es necesario abordar la prisión desde distintos enfoques: social, económico, político y cultural. La idea es guiarlo, como participante, en la profundización sobre el abolicionismo penal y modelos alternativos de justicia (como la restaurativa). Objetivos específicos: * Comprender los pilares fundamentales de las propuestas abolicionistas a partir de las nociones básicas, las razones de su surgimiento y los principios elementales de esta propuesta. * Comprender el carácter selectivo de los sistemas punitivos en distintos contextos sociales e históricos, a partir de la presentación de tres hitos de sistemas punitivos con el fin de demostrar que, a pesar de las diferencias, estos conservan rasgos identitarios propios de los sistemas punitivos como el carácter selectivo de los castigos, cuyo propósito es privilegiar a los sectores sociales dominantes. Los tres hitos históricos que veremos son: Código Hammurabi, la Inquisición y las workhouses. * Identificar las ideas centrales de los abolicionistas europeos. * Comprender que hay intereses económicos involucrados en la privación de la libertad. Utilizaremos como ejemplo a Estados Unidos, donde se dará cuenta de las promesas, funcionamiento y consecuencias del modelo privatizador en el sistema carcelario. * Conocer algunos exponentes y planteamientos del abolicionismo en América Latina, de tal manera que se puedan comprender algunas propuestas o experiencias abolicionistas en esta región, específicamente en Brasil y Argentina. * Identificar los elementos de una justicia restaurativa que abra la puerta a la propuesta abolicionista. Para ello, encontrará la explicación del concepto de justicia restaurativa, el contexto en el cual surgió y el desarrollo que ha tenido. También se expondrán los principales rasgos característicos y el alcance abolicionista de este tipo de justicia.
description: Este curso de duración de 30 horas, permite conocer, analizar y reflexionar entorno al abolicionismo penal y profundizar en modelos alternativos de justicia (como la restaurativa); sin embargo, se recomiendan conocimientos generales de política criminal y derecho penal.

description: Magnetic form factors corresponding to elastic electron scattering from odd-A nuclei are presented. The calculations are carried out in plane-wave Born approximation. The one-body properties are obtained in a deformed self-consistent mean-field calculation based on a Skyrme HF+BCS method. Collective effects are also included in the cranking approximation. Results on several stable nuclei are compared with the available experimental information. It is shown that a deformed formalism improves the agreement with experiment in deformed nuclei, while reproducing equally well spherical nuclei by taking properly the spherical limit of the deformed model and the effect of nucleon-nucleon correlations. Thus, the capability of the model to describe magnetic form factors is demonstrated. This opens the door to explore also unstable nuclei of particular interest that could be measured in future experiments on electron-radioactive beam colliders.

description: We report first-principles investigations of magnetocrystalline anisotropy energy (MCAE) oscillations as a function of capping layer thickness in Heusler alloy Co\textsubscript{2}FeAl/Ta heterostructures. Substantial oscillation is observed in FeAl-interface structure. According to $k$-space and band-decomposed charge density analyses, this oscillation is mainly attributed to the Fermi-energy-vicinal quantum well states (QWS) which are confined between Co\textsubscript{2}FeAl/Ta interface and Ta/vacuum surface. The smaller oscillation magnitude in the Co-interface structure can be explained by the smooth potential transition at the interface. These findings clarify that MCAE in Co\textsubscript{2}FeAl/Ta is not a local property of the interface and that the quantum well effect plays a dominant role in MCAE oscillations of the heterostructures. This work presents the possibility of tuning MCAE by QWS in capping layers, and paves the way for artificially controlling magnetic anisotropy energy in magnetic tunnel junctions.

Abstract FKB238 is a biosimilar of bevacizumab (a monoclonal antibody against vascular endothelial growth factor) approved for use in the same types of cancer as reference bevacizumab. FKB238 has similar physicochemical and pharmacodynamic properties to those of reference bevacizumab and pharmacokinetic equivalence was shown in healthy volunteers and in patients with non-small cell lung cancer (NSCLC). FKB238 demonstrated equivalent clinical efficacy to reference bevacizumab in patients with advanced or recurrent nonsquamous NSCLC, with similar tolerability, safety and immunogenicity profiles.

description: We propose a model for modular synchronous systems with combinational dependencies and define consistency using this model. We then show how to derive this model from a modular specification where individual modules are specified as Kripke Structures and give an algorithm to check the system for consistency. We have implemented this algorithm symbolically using BDDs in a tool, SpecCheck. We have used this tool to check an example bus protocol derived from an industrial specification. The counterexamples obtained for this protocol highlight the need for consistency checking.

description: Discharge capillary-based active plasma lenses are a promising new technology for strongly focusing charged particle beams, especially when combined with novel high gradient acceleration methods. Still, many questions remain concerning such lenses, including their transverse field uniformity, limitations due to plasma wakefields and whether they can be combined in multi-lens lattices in a way to cancel chromaticity. These questions will be addressed in a new plasma lens experiment at the CLEAR User Facility at CERN. All the subsystems have been constructed, tested and integrated into the CLEAR beam line, and are ready for experiments starting late 2017.

Extended self-similarity in two-dimensional complex plasmas

Subjects: subject: Plasma Physics (physics.plasm-ph)

description: Self-similarity is a property of an object or process wherein a part is similar to the whole. Mathematically, it can often be expressed as a power-law scaling of the quantity of interest. Extended self-similarity is a concept widely used in the field of turbulence and refers to the power-law scaling of the longitudinal structure functions of the velocity field expressed through the structure functions of different orders, rather than distance. Originally discovered by [R. Benzi et al., Phys. Rev. E 48, R29 (1993)] in fully developed turbulence, it was later found to hold in other situations and systems as well. In this paper, we show that in an active-matter system, extended self-similarity is possible even without the presence of respective power-law scaling in the underlying structure functions of distance. The active-matter system used in this study was a single-layer suspension of active Janus particles in a plasma. Janus particles are polymer microspheres with hemispherical metal coating. When dispersed in a plasma, they acquire self-propulsion and act as microswimmers. Extended self-similarity was also observed in the velocity field of a single-layer suspension of laser-heated regular (passive) particles, where the underlying structure functions displayed a hint of the power-law scaling near the mean interparticle distance. Therefore, it appears to be an inherent characteristic of complex plasmas.

description: We study a simple TeV-scale model of baryon number violation which explains the observed proximity of the dark matter and baryon abundances. The model has constraints arising from both low and high-energy processes, and in particular, predicts a sizable rate for the neutron-antineutron ($n-\bar{n}$) oscillation at low energy and the monojet signal at the LHC. We find an interesting complementarity among the constraints arising from the observed baryon asymmetry, ratio of dark matter and baryon abundances, $n-\bar{n}$ oscillation lifetime and the LHC monojet signal. There are regions in the parameter space where the $n-\bar{n}$ oscillation lifetime is found to be more constraining than the LHC constraints, which illustrates the importance of the next-generation $n-\bar{n}$ oscillation experiments.

Utiliza como marco de referencia el análisis de políticas públicas y las teorías económicas de interferencia y captura del Estado. Analiza la evolución de la política de vivienda social en Colombia a partir de la década de los noventa, que transitó desde la producción publica de vivienda hacia el papel del Estado como regulador y otorgante de subsidios a la demanda. Define la captura del Estado como un acto complejo entre agentes públicos, privados y de la sociedad civil intervinientes, en el cual es necesario valorar la concurrencia de dos situaciones: en primer lugar, acciones por parte de los agentes privados para influir en las determinaciones de los agentes del Estado, y, en segundo lugar, decisiones de las autoridades para beneficiar de manera extraordinaria al sector privado. Con base en información recaudada sobre el proceso de formulación de los Macroproyectos de Interés Social Nacional, se identifican hechos de ambas categorías, afrentas a normas constitucionales y pobre desempeño en materia de política de vivienda en el período estudiado.
description: The research project characterizes and values the participation of private agents in the formulation of public policy, through the case of Macro projects of National Social lnterest, developed in Colombia in the period 2002-2018, in the context of social housing policy. lt uses public policy analysis and economic theories of interference and state capture as a framework of reference. lt analyzes the evolution of social housing policy in Colombia since the 1990s, which shifted from the public production of housing to the State's role as a regulator and provider of subsidies to meet demand. The project defines the capture of the state as a complex act involving public, prívate, and civil society agents, in which it is necessary to assess the occurrence of two situations: first, actions by prívate agents to influence the decisions of state agents, and secondly, decisions by the authorities to benefit the prívate sector in an extraordinary way. Based on information collected about the formulation process of the Macro projects of National Social lnterest, events from both categories are identified, revealing violations of constitutional norms and poor performance in housing policy during the studied period.

description: We adapt our recently proposed dual messenger algorithm for spin field reconstruction and showcase its efficiency and effectiveness in Wiener filtering polarized cosmic microwave background (CMB) maps. Unlike conventional preconditioned conjugate gradient (PCG) solvers, our preconditioner-free technique can deal with high-resolution joint temperature and polarization maps with inhomogeneous noise distributions and arbitrary mask geometries with relative ease. Various convergence diagnostics illustrate the high quality of the dual messenger reconstruction. In contrast, the PCG implementation fails to converge to a reasonable solution for the specific problem considered. The implementation of the dual messenger method is straightforward and guarantees numerical stability and convergence. We show how the algorithm can be modified to generate fluctuation maps, which, combined with the Wiener filter solution, yield unbiased constrained signal realizations, consistent with observed data. This algorithm presents a pathway to exact global analyses of high-resolution and high-sensitivity CMB data for a statistically optimal separation of E and B modes. It is therefore relevant for current and next-generation CMB experiments, in the quest for the elusive primordial B-mode signal.

description: A high statistics data sample of the $K^{+}$ decays is recorded by the OKA collaboration. A missing mass analysis is performed to search for a light invisible pseudoscalar axion-like particle (ALP) $a$ in the decay $K^{+} \to π^{+} π^{0} a$. No signal is observed, the upper limits for the branching ratio of the decay are calculated. The $90\%$ confidence level upper limit is changing from $2.5\cdot10^{-6}$ to $2\cdot10^{-7}$ for the ALP mass from 0 to 200 MeV/$c^{2}$, except for the region of $π^{0}$ mass, where the upper limit is $4.4\cdot10^{-6}$.

description: We study the interaction of a low-mass planet with a protoplanetary disk with a realistic treatment of the energy balance by doing radiation-hydrodynamical simulations. We look at accretion and migration rates and compare them to isothermal studies. We used a three-dimensional version of the hydrodynamical method RODEO, together with radiative transport in the flux-limited diffusion approach. The accretion rate, as well as the torque on the planet, depend critically on the ability of the disk to cool efficiently. For densities appropriate to 5 AU in the solar nebula, the accretion rate drops by more than an order of magnitude compared to isothermal models, while at the same time the torque on the planet is positive, indicating outward migration. It is necessary to lower the density by a factor of 2 to recover inward migration and more than 2 orders of magnitude to recover the usual Type I migration. The torque appears to be proportional to the radial entropy gradient in the unperturbed disk. These findings are critical for the survival of protoplanets, and they should ultimately find their way into population synthesis models.

description: We undertake a theoretical analysis to probe the Kerr spectrum within the superconducting phase of strontium ruthenate, where the Kerr rotation experiments demonstrate the existence of a superconducting state with broken time reversal symmetry. We find that spin-orbit coupling changes the hybridization along the Fermi surface's diagonal zone mainly affects Hall transport. We show that the dominant Hall response arises mainly from the quasi-1D orbitals $d_{yz}$ and $d_{xz}$, linked to their hybridization, while other contributions are negligible. This establishes that, the breaking of time reversal symmetry of quasi-1D orbitals can account for the existence of the Kerr angle, irrespective of the order symmetry specific to the $d_{xy}$ orbital. Moreover, the optical Hall conductivity and Kerr angle estimated for the hypothesised superconducting orders also closely match the experimental findings, providing important novel insight on the role of the spin-orbit coupling, hybridization, and emergent order.

description: We describe recent progress in understanding the continuous symmetry properties of non-Hermitian, PT-symmetric quantum field theories. Focussing on a simple non-Hermitian theory composed of one complex scalar and one complex pseudoscalar, we revisit the derivation of Noether's theorem to show that the conserved currents of non-Hermitian theories correspond to transformations that do not leave the Lagrangian invariant. We illustrate the impact that this has on the consistent formulation of (Abelian) gauge theories by studying a non-Hermitian extension of scalar quantum electrodynamics. We consider the spontaneous breakdown of both global and local symmetries, and describe how the Goldstone theorem and the Englert-Brout-Higgs mechanism are borne out for non-Hermitian, PT-symmetric theories.

description: We present and explore deep narrow- and medium-band data obtained with the Subaru and the Isaac Newton telescopes in the ~2 deg$^2$ COSMOS field. We use these data as an extremely wide, low-resolution (R~20-80) IFU survey to slice through the COSMOS field and obtain a large sample of ~4000 Lyman-$α$ (Lya) emitters from z~2 to z~6 in 16 redshift slices (SC4K). We present new Lya luminosity functions (LFs) covering a co-moving volume of ~10$^8$Mpc$^3$. SC4K extensively complements ultra-deep surveys, jointly covering over 4 dex in Lya luminosity and revealing a global (2.53.5, likely linked with the evolution of the AGN population. The Lya luminosity density rises by a factor ~2 from z~2 to z~3 but is then found to be roughly constant (~$1.1\times10^{40}$ erg s$^{-1}$ Mpc$^{-3}$) to z~6, despite the ~0.7 dex drop in UV luminosity density. The Lya/UV luminosity density ratio rises from $4\pm1$% to $30\pm6$% from z~2.2 to z~6. Our results imply a rise of a factor of ~2 in the global ionisation efficiency ($ξ_{\rm ion}$) and a factor ~$4\pm1$ in the Lya escape fraction from z~2 to z~6, hinting for evolution in both the typical burstiness/stellar populations and even more so in the typical ISM conditions allowing Ly$α$ photons to escape.

La question du « choix » dans la décision de se marier ou non au Québec

description: Résumé Dans le débat sur la pertinence d’un encadrement légal de l’union libre, le législateur québécois a jusqu’à maintenant soutenu l’importance de préserver le libre choix des individus qui souhaitent vivre en dehors des cadres du mariage. Un tel argument repose sur quatre postulats quant au « choix » que font les couples lorsqu’ils prennent la décision de se marier ou non, postulats qui ne sont étayés par aucune étude empirique. En tenant compte du point de vue des couples sur la vie conjugale et à l’aide de notions de sociologie du droit telles l’internormativité, la conscience du droit et l’effectivité des lois, l’article montre que la décision des couples de se marier ou non repose en fait sur des motifs et des normes qui n’ont souvent rien de juridique, et que l’imposition d’un statut de « conjoint de fait » par les lois sociales et fiscales entretient la perception répandue mais erronée selon laquelle les conjoints de fait jouiraient, après quelques années de vie commune ou la naissance d’un enfant, d’un statut et d’une protection équivalents à ceux des couples mariés. Abstract In the debate over whether or not legislation is needed to regulate common-law marriage, Quebec lawmakers have so far maintained that it is important to preserve the free choice of individuals who wish to live together outside the institution of marriage. This position rests on four premises regarding the “choice” that couples make when they decide to marry or not – premises that are not based on any empirical findings. Taking into consideration the views of couples on married life and applying concepts from the sociology of law such as internormativity, legal consciousness and efficacy of legislation, this paper shows that the decision to marry or not is in fact founded on reasons and norms that often have no legal basis, and that the reference to “common-law” status in social and tax legislation perpetuates the widespread but mistaken belief that couples in common-law relationships, after living together for a few years or having a child together, enjoy a status or protection equivalent to that of married couples.

description: The present work aims to offer theorical and practical evidence to challenge the current scope of the victims’ rights to a remedy, truth, and reparation in the case of individuals with dissident sexual orientations and gender identities. To that end, it begins by describing basic notions of the alternative discourses on human sexuality which promoted those subject’s political emancipation during the 20th century. Subsequently, it elaborates the meanings of homosexual, lesbian, bisexual and trans identities, describing their historical roots, and inquiring into personal adscription processes. In addition, it examines the specific dynamics of violence they endure both worldwide and in the Spanish region of Catalonia. Finally, the study addresses the conventional functioning of the human rights system vis-à-vis LGBT people, detailing the international standards of the rights to a remedy, truth, and reparation, in order to analyze them in the light of the previous findings and offer proposals for legal reform.

description: Our goal is to automatically detect boundaries between discussions of different topics in meetings. Towards this end we adapt the TextTiling algorithm [1] to the context of meetings. Our features include not only the overlapped words between adjacent windows, but also overlaps in the amount of speech contributed by each meeting participant. We evaluate our algorithm by comparing the automatically detected boundaries with the true ones, and computing precision, recall and f–measure. We report average precision of 0.85 and recall of 0.59 when segmenting unseen test meetings. Error analysis of our results shows that although the basic idea of our algorithm is sound, it breaks down when participants stray from typical behavior (such as when they monopolize the conversation for too long).

These hands are responsible for planting the flowers, watering them, caring for them, cutting them and arranging them for dispatch; hands that have received thousands of cuts because of their important and little recognized work, hands that also carry a weight on them, hands that struggle, hands that have been invisibilized. In this scenario, workers appear as instruments that must submit to this logic, which does not allow them to BE, but play the role of production indicator, degrading them as workers and people.

description: Die Nutzung nachhaltiger Energieressourcen ist in der heutigen Zeit unvermeidbar. Jedes Jahr steigt der Anteil der erneuerbaren Energieressourcen in Deutschland und damit auch der Anteil der geothermisch erzeugten Energie. Das größte thermische Potential liegt in tiefen, harten Formationen. Da die Bohrkosten mit zunehmender Tiefe exponentiell ansteigen, ist die tiefe Geothermie ein kostenintensives Unterfangen, bei dem Kostensenkungen gefragt sind. Eine Maßnahme zur Kostenreduktion ist das wasserstrahlbasierte Bohren. Dabei wird das Gestein nicht durch mechanische Bearbeitung mittels Bohrmeißel, sondern durch die hydraulische Energie eines Hochdruckwasserstrahls abgetragen. Kavitation und auch der durch Pulsation periodisch aufkommende Wasserhammereffekt steigern den Gesteinsabtrag und führen somit zu einem effizienteren Bohrfortschritt. Die in dieser Studie betrachtete Wasserstrahldüse ist eine selbst-resonante Düse. In dieser kavitiert und pulsiert der Wasserstrahl aufgrund in einer Resonatorkammer aufkommenden Kelvin-Helmholtz-Instabilitäten. Für die Experimente wurde ein Prüfstand aufgebaut, der aus einer Hochdruckpumpe, einem Autoklaven mit Sichtfenstern und Messtechnik besteht. Die Düse wurde im Autoklaven mit einstellbarem Zellendruck untersucht. Ziel der Experimente war es, die Pulsationsfrequenz sowie die Wolkengröße der Kavitation mittels AE (acoustic emission) -Sensorik messen zu können. Die Messdaten wurden durch eine optische Überwachung mit Hilfe von Schattenbildverfahren verifiziert. Zu diesem Zweck wurde eine Hochgeschwindigkeitskamera mit bis zu 1.000.000 Bildern pro Sekunde eingesetzt. Die Experimente haben nachgewiesen, dass eine Korrelation zwischen den AE-Messdaten und der durch Schattenbildverfahren gemessenen Wolkengröße besteht. Darüber hinaus konnte die Pulsationsfrequenz der Kavitationswolken durch AE-Sensorik gemessen werden. Außerdem haben die Experimente gezeigt, dass die Pulsationsfrequenz und die Wolkengröße in Abhängigkeit zum Druckverhältnis Zellendruck/Düsenvordruck, sowie auch zum Düsenvordruck stehen.

description: We establish a general Rashba Hamiltonian for trilayer graphene (TLG) by introducing an extrinsic layer-dependent Rashba spin-orbit coupling (SOC) arising from the off-plane inversion symmetry breaking. Our results indicate that the band spin splitting depends strongly on the layer-distribution and sign of Rashba SOC as well as the ABA or ABC stacking order of TLG. We find that spin splitting is significantly enhanced as the number of layers of the Rashba SOC with the same sign and magnitude increases. For the spatially-separated two Rashba SOCs of the same magnitude but the opposite sign, no spin splitting arises in ABC-TLG due to the preservation of inversion symmetry that ensures the complete cancellation of contributions from the opposite layers, whereas nonzero spin splitting is observed for ABA-TLG due to its own lack of inversion symmetry. We further illustrate that gate voltage is effective to modulate the spin-polarized states near the band edges. Moreover, we use density functional theory calculations to verify the Rashba splitting effect in the example of TLG interfaced by Au layer(s), which induce simultaneously the effective terms of Rashba SOC and gate voltage. Our results demonstrate the significance of layer and symmetry in manipulating spin and can be extended to multilayer graphene or other van der Waals interface systems.

description: ENGLISH. Too often public policies are developed in an attempt to solve complex problems but once under implementation, fail to have the expected impact on those problems. In this paper, we define the “implementation gap” as the disparity between the desired outcomes set by public sector organizations and their actual performance on the ground. Approaches and tools to tackle the implementation challenges in complex situations rely on a new generation of principles that often imply the need for action-based, iterative and adaptive public management models. Drawing from the most recent body of knowledge in the field of implementation and the science of public policy delivery , this analysis has allowed us to create a model that highlights key drivers of implementation. This new governance model which aims to tackle the implementation gap in the public sector is called the RACE model-based on four components which are: driving Results, driving Adaptability, driving Capacity, and driving Engagement. This paper describes a range of implementation approaches that have evolved over the last decades and introduces the RACE framework as a way to narrowing the implementation gap. FRANÇAIS. Trop souvent, les politiques publiques sont élaborées pour tenter de résoudre des problèmes complexes mais, une fois mises en œuvre, elles ne parviennent pas à avoir l'impact escompté sur ces problèmes. Dans ce document, nous définissons le "déficit de mise en œuvre" comme la disparité entre les résultats souhaités par les organismes du secteur public et leurs performances réelles sur le terrain. Les approches et les outils permettant de relever les défis de la mise en œuvre dans des situations complexes reposent sur une nouvelle génération de principes qui impliquent souvent la nécessité d’emprunter de nouveaux modèles de gestion publique fondés sur l'action, l’itération et l’adaptabilité. En s'appuyant sur les connaissances les plus récentes dans le domaine de la mise en œuvre et de la science de la prestation des politiques publiques, cette analyse nous a permis de créer un modèle qui met en évidence les principaux moteurs de la mise en œuvre. Ce nouveau modèle de gouvernance visant à combler le déficit de mise en œuvre, est appelé modèle RACE et repose sur quatre éléments : les résultats, l'adaptabilité, la capacité et l'engagement. Ce document décrit une série d'approches portant sur la mise en œuvre ayant évolué au cours dernières décennies et présente le cadre RACE comme un moyen de réduire l'écart de mise en œuvre.

description: La figura de Empresa Industrial y Comercial del Estado, demanda una legislación que de una parte garantice la igualdad de competencia con otros agentes del mercado estando libre de prerrogativas en desmedro de sus competidores, desventajas o injerencia política, tal como lo recomiendan las organizaciones internacionales expertas en la materia; y de otra parte requiere que se respeten los principios constitucionales, legales y jurisprudenciales en materia de compras públicas, a fin de garantizar una correcta ejecución del patrimonio público que compone su capital social. El legislador ha propugnado por expedir normativa especial en materia de contratación para esta tipología, sin embargo la práctica vislumbra que se está lejos de cumplir los objetivos, no se ha podido garantizar adecuadamente, de un lado el cuidado debido por la ejecución de recursos públicos, y de otro la igualdad de armas para actuar como un agente más dentro del mercado. Desde la legislación se requieren realizar los ajustes pertinentes para lograr la salvaguarda del patrimonio estatal procurando las libertades requeridas por un agente del mercado. Este objetivo se muestra en la práctica como de difícil cumplimiento absoluto, pero se debe lograr en la mayor medida de lo posible.
description: The figure of State Industrial and Commercial Company, demands legislation that on the one hand guarantees equal competition with other market agents, being free of prerogatives to the detriment of its competitors, disadvantages or political interference, as recommended by international expert organizations in the matter; and on the other hand, it requires that the constitutional, legal and jurisprudential principles regarding public purchases be respected, in order to guarantee a correct execution of the public patrimony that makes up its social capital. The legislator has advocated issuing special regulations on contracting for this typology, however, practice shows that the objectives are far from being met, it has not been possible to adequately guarantee, on the one hand, the due care for the execution of public resources, and on the other, equality of arms to act as one more agent within the market. From the legislation it is required to make the pertinent adjustments to achieve the safeguard of the state patrimony seeking the freedoms required by a market agent. This objective is shown in practice to be difficult to achieve completely, but it must be achieved to the greatest extent possible.

description: We demonstrate our game theory-based Texas Hold’em poker player. To overcome the computational diﬃculties stemming from Texas Hold’em’s gigantic game tree, our player uses automated abstraction and real-time equilibrium approximation. Our player solves the ﬁrst two rounds of the game in a large oﬀ-line computation, and solves the last two rounds in a real-time equilibrium approximation. Participants in the demonstration will be able to compete against our opponent and experience ﬁrst-hand the cognitive abilities of our player. Some of the techniques used by our player, which does not directly incorporate any poker-speciﬁc expert knowledge, include such poker techniques as bluﬃng, slow-playing, check-raising, and semi-bluﬃng, all techniques normally associated with human play.

description: Cosmological models with two interacting fluids, each satisfying the strong energy condition, are studied in the framework of classical General Relativity. If the interactions are phenomenologically described by a power law in the scale factor, the two initial interacting fluids can be equivalently substituted by two non interacting effective fluids, where one of them may violate the strong energy condition and/or have negative energy density. Analytical solutions of the Friedmann equations of this general setting are obtained and studied. One may have, depending on the scale where the interaction becomes important, non singular universes with early accelerated phase, or singular models with transition from decelerated to accelerated expansion at large scales. Among the first, there are bouncing models where contraction is stopped by the interaction. In the second case, one obtains dark energy expansion rates without dark energy, like $Λ$CDM or phantomic accelerated expansions without cosmological constant or phantoms, respectively.
