description: El contacto que establecen los diferentes grupos de interés con las ramas del poder público del Estado es una práctica tan antigua como su propia fundación, la cual resulta natural en el marco de la democracia participativa ya que en esa interacción se construyen las relaciones sociales, económicas y políticas de una sociedad, sin embargo, debe ser objeto de regulación para garantizar la transparencia tanto de los servidores del Estado como de los representantes de las diversas colectividades. Apelando a la metodología propuesta por el public choice es posible diseñar un marco regulatorio que atienda el mandato institucional consignado en la normatividad colombiana y que garantice el acceso a la información y la libre concurrencia al mercado de gestión de intereses, tal y como ocurre en varios países del mundo y así minimizar el riesgo de caer en prácticas como la captura del regulador, la corrupción o el intercambio de favores.
description: The contact that is stablished between the different interest groups and the Branches of the State Public Power is as an old practice as its very foundation, which is natural in the framework of participatory democracy since in this interaction social, economic and political relations of a society are built. However, it must be an aspect of regulation to guarantee the transparency of both the State servants and the representatives of the various communities. Using the methodology proposed by the public choice, it is possible to design a regulatory framework that meets the institutional mandate consigned in Colombian regulations and that guarantees access to information and free concurrence in the interest management market, as occurs in several countries of the world and in that way minimize the risk of falling into practices such as the capture of the regulator, corruption or the exchange of favors.

description: We report on quantum frequency conversion of memory-compatible narrow-bandwidth photons at 606 nm to the telecom C-band at 1552$\,$nm. The 200$\,$ns long photons, compatible with Praseodymium-based solid-state quantum memories are frequency converted using a single-step difference frequency generation process in a periodically poled Lithium Niobate waveguide. We characterize the noise processes involved in the conversion and by applying strong spectral filtering of the noise, we demonstrate high signal-to-noise ratio conversion at the single photon level (SNR$\,>\,$100 for a mean input photon number per pulse of 1). We finally observe that a memory compatible heralded single photon with a bandwidth of 1.8$\,$MHz, obtained from a spontaneous parametric down conversion pair source, still shows a strong non-classical behavior after conversion. We first demonstrate that correlations between heralding and converted heralded photons stay in the non-classical regime. Moreover, we measured the heralded autocorrelation function of the heralded photon using the converter device as a frequency-domain beam splitter, yielding a value of $0.19\pm0.07$. The presented work represents a step towards the connection of several quantum memory systems emitting narrow-band visible photons to the telecommunication wavelengths.

description: We propose a new fast method to match factorization theorems applicable in different kinematical regions, such as the transverse-momentum-dependent and the collinear factorization theorems in Quantum Chromodynamics. At variance with well-known approaches relying on their simple addition and subsequent subtraction of double-counted contributions, ours simply builds on their weighting using the theory uncertainties deduced from the factorization theorems themselves. This allows us to estimate the unknown complete matched cross section from an inverse-error-weighted average. The method is simple and provides an evaluation of the theoretical uncertainty of the matched cross section associated with the uncertainties from the power corrections to the factorization theorems (additional uncertainties, such as the nonperturbative ones, should be added for a proper comparison with experimental data). Its usage is illustrated with several basic examples, such as $Z$ boson, $W$ boson, $H^0$ boson and Drell-Yan lepton-pair production in hadronic collisions, and compared to the state-of-the-art Collins-Soper-Sterman subtraction scheme. It is also not limited to the transverse-momentum spectrum, and can straightforwardly be extended to match any (un)polarized cross section differential in other variables, including multi-differential measurements.

description: The number of two-qubit gates required to transform deterministically a three-qubit pure quantum state into another is discussed. We show that any state can be prepared from a product state using at most three CNOT gates, and that, starting from the GHZ state, only two suffice. As a consequence, any three-qubit state can be transformed into any other using at most four CNOT gates. Generalizations to other two-qubit gates are also discussed.

description: En esta investigación se explica el comportamiento histórico de la propiedad de la tierra en Colombia durante más de cinco siglos y su influencia sobre las estructuras políticas y económicas del país a partir de las dinámicas de cambio y continuidad institucional, apoyándose particularmente en el uso del enfoque institucionalista histórico y la nueva economía institucional. Para tal fin, se formuló una premisa orientadora que acepta la persistencia de unos rasgos de carácter señorial, propios del ordenamiento institucional proveniente de la conquista y la colonia e incluso del mundo ibérico medieval, lo cual, ha sido relevante en la conformación de una democracia clientelista que no logra su plena consolidación en términos de ciudadanía, así como un capitalismo con ciertas características aun premodernas que no logra consolidar a plenitud elementos básicos para su funcionamiento como los derechos de propiedad. El diseño metodológico fue esencialmente cualitativo, mediante la interpretación analítica de fuentes documentales, autores referentes en la investigación historiográfica y teóricos del pensamiento institucionalista, para lo cual, se construyó y aplicó un instrumento teórico de análisis, apto para ser replicado en otras investigaciones que aborden largos periodos de tiempo, lo cual, se constituye en uno de los principales aportes de esta investigación.
description: This research explains the historical behavior of land ownership in Colombia for more than five centuries and its influence on political and economic structures of this country studying change and institutional continuity dynamics, particularly through the new economic history approach. For this purpose, was formulated a guiding premise that accepts the persistence of some features of a stately character, typical of the institutional order coming from the conquest and the colony and even from the medieval Iberian world, which has been relevant in the formation of a clientelist democracy that does not achieve its full consolidation in terms of citizenship and a capitalism with certain pre-modern characteristics that does not manage to fully consolidate basic elements for its functioning such as property rights. The methodological design was essentially qualitative, through the analytical interpretation of documentary sources, leading authors in historiographic research and theorists of institutionalism, for which a theoretical analysis instrument was constructed and applied, suitable for being replicated in others long periods of time research, which is one of the main contributions of this research.

The experimental bound on Delta rho constitutes a strong constraint on the masses and mixings of the scalar particles in that model.

description: We study the regularity and well-posedness of the local, first-order forward-backward mean field games system, assuming a polynomially growing cost function and a Hamiltonian of quadratic growth. We consider systems and terminal data that are strictly monotone in the density and study two different regimes depending on whether there exists a lower bound for the running cost function. The work relies on a transformation due to P.-L. Lions, which gives rise to an elliptic partial differential equation with oblique boundary conditions, that is strictly elliptic when the coupling is unbounded from below. In this case, we prove that the solution is smooth. When the problem is degenerate elliptic, we obtain existence and uniqueness of weak solutions analogous to those obtained by P. Cardaliaguet and P.J. Graber for the case of a terminal condition that is independent of the density. The weak solutions are shown to arise as viscous limits of classical solutions to strictly elliptic problems.

description: This article introduces false discovery rate regression, a method for incorporating covariate information into large-scale multiple-testing problems. FDR regression estimates a relationship between test-level covariates and the prior probability that a given observation is a signal. It then uses this estimated relationship to inform the outcome of each test in a way that controls the overall false discovery rate at a prespecified level. This poses many subtle issues at the interface between inference and computation, and we investigate several variations of the overall approach. Simulation evidence suggests that: (1) when covariate effects are present, FDR regression improves power for a fixed false-discovery rate; and (2) when covariate effects are absent, the method is robust, in the sense that it does not lead to inflated error rates. We apply the method to neural recordings from primary visual cortex. The goal is to detect pairs of neurons that exhibit fine-time-scale interactions, in the sense that they fire together more often than expected due to chance. Our method detects roughly 50% more synchronous pairs versus a standard FDR-controlling analysis. The companion R package FDRreg implements all methods described in the article. Supplementary materials for this article are available online.

description: We construct an action for NSNS 5-branes which is manifestly covariant under O(d,d). This is done by doubling $d$ of the spacetime coordinates which appear in the worldvolume action. By formulating the DBI part of the action in a manner similar to a "gauged sigma model", only half the doubled coordinates genuinely appear. Our approach allows one to describe the full T-duality orbit of the IIB NS5 brane, the IIA KKM and their exotic relations in one formalism. Furthermore, by using ideas from double field theory, our action can be said to describe various aspects of non-geometric five-branes.

description: Using an analytically tractable kinetic model of a two dimensional Fermi liquid of electrons, we characterize the crossovers between zero sound, first sound and plasmons. For experimentally realized Fermi liquids in a hydrodynamic limit, both zero and first sound waves are essentially replaced by plasmons. The plasmon dispersion relation is robust against hydrodynamic effects, up to acquiring the viscous-limited decay rate of a first sound wave in the hydrodynamic limit. We discuss implications for experiments in clean two dimensional electron gases.

description: This publication introduces a groundbreaking theoretical framework known as the Plhák Unifying Principle (PSP). The PSP links neutrino oscillations, weak interaction, and spacetime curvature with the distribution of dark matter and dark energy. The theory explores how the energy and mass of neutrinos change over time, influencing the curvature of spacetime and the structure of the universe. Furthermore, it postulates that neutrino mass is variable and declines with distance, and it discusses how this impacts dark matter's concentration around baryonic structures. This theory also critiques the concept of virtual mass, proposing instead that neutrinos maintain a fluctuating frequency that plays a fundamental role in cosmic expansion and large-scale structure formation.The long-term outlook of PSP suggests that neutrinos may be central to our understanding of gravity and cosmology, paving the way for further experimental validation and discovery. The results of this theory hold potential for reshaping our comprehension of dark matter and energy, and unify key aspects of weak forces and gravitational phenomena.

description: We study the problem of folding a polyomino $P$ into a polycube $Q$, allowing faces of $Q$ to be covered multiple times. First, we define a variety of folding models according to whether the folds (a) must be along grid lines of $P$ or can divide squares in half (diagonally and/or orthogonally), (b) must be mountain or can be both mountain and valley, (c) can remain flat (forming an angle of $180^\circ$), and (d) must lie on just the polycube surface or can have interior faces as well. Second, we give all the inclusion relations among all models that fold on the grid lines of $P$. Third, we characterize all polyominoes that can fold into a unit cube, in some models. Fourth, we give a linear-time dynamic programming algorithm to fold a tree-shaped polyomino into a constant-size polycube, in some models. Finally, we consider the triangular version of the problem, characterizing which polyiamonds fold into a regular tetrahedron.

description: We consider the string-net model obtained from $SU(2)_2$ fusion rules. These fusion rules are shared by two different sets of anyon theories. In this work, we study the competition between the two corresponding non-Abelian quantum phases in the ladder geometry. A detailed symmetry analysis shows that the nontrivial low-energy sector corresponds to the transverse-field cluster model that displays a critical point described by the $so(2)_1$ conformal field theory. Other sectors are obtained by freezing spins in this model.

polyketide compound

description: The polyketide griseofulvin is a natural antifungal compound and research in griseofulvin has been key in establishing our current understanding of polyketide biosynthesis. Nevertheless, the griseofulvin gsf biosynthetic gene cluster (BGC) remains poorly understood in most fungal species, including Penicillium griseofulvum where griseofulvin was first isolated. To elucidate essential genes involved in griseofulvin biosynthesis, we performed third-generation sequencing to obtain the genome of Penicillium griseofulvum strain D-756. Furthermore, we gathered publicly available genome of 11 other fungal species in which gsf gene cluster was identified. In a comparative genome analysis, we annotated and compared the gsf BGC of all 12 fungal genomes. Our findings show no gene rearrangements at the gsf BGC. Furthermore, seven gsf genes are conserved by most genomes surveyed whereas the remaining six were poorly conserved. This study provides new insights into differences between gsf BGC and suggests that seven gsf genes are essential in griseofulvin production.

description: The shear flow of two dimensional foams is probed as a function of shear rate and disorder. Disordered foams exhibit strongly rate dependent velocity profiles, whereas ordered foams show rate independence. Both behaviors are captured quantitatively in a simple model based on the balance of the time-averaged drag forces in the foam, which are found to exhibit power-law scaling with the foam velocity and strain rate. Disorder modifies the scaling of the averaged inter-bubble drag forces, which in turn causes the observed rate dependence in disordered foams.

description: Here we consider the nonlinear evolution of Alfven waves that have been excited by gravitational waves from merging binary pulsars. We derive a wave equation for strongly nonlinear and dispersive Alfven waves. Due to the weak dispersion of the Alfven waves, significant wave steepening can occur, which in turn implies strong harmonic generation. We find that the harmonic generation is saturated due to dispersive effects, and use this to estimate the resulting spectrum. Finally we discuss the possibility of observing the above process.

description: We present a method for multiple hypothesis testing that maintains control of the False Discovery Rate while incorporating prior information about the hypotheses. The prior information takes the form of p-value weights. If the assignment of weights is positively associated with the null hypotheses being false, the procedure improves power, except in cases where power is already near one. Even if the assignment of weights is poor, power is only reduced slightly, as long as the weights are not too large. We also provide a similar method to control False Discovery Exceedance.

description: Spin-orbital-angular-momentum (SOAM) coupling has been realized in recent experiments of Bose-Einstein condensates [Chen et al., Phys. Rev. Lett. 121, 113204 (2018) and Zhang et al., Phys. Rev. Lett. 122, 110402 (2019)], where the orbital angular momentum imprinted upon bosons leads to quantized vortices. For fermions, such an exotic synthetic gauge field can provide fertile ground for fascinating pairing schemes and rich superfluid phases, which are yet to be explored. Here we demonstrate how SOAM coupling stabilizes vortices in Fermi superfluids through a unique mechanism that can be viewed as the angular analog to that of the spin-orbit-coupling-induced Fulde-Ferrell state under a Fermi surface deformation. Remarkably, the vortex size is comparable with the beam waist of Raman lasers generating the SOAM coupling, which is typically much larger than previously observed vortices in Fermi superfluids. With tunable size and core structure, these giant vortex states provide unprecedented experimental access to topological defects in Fermi superfluids.

By modulating the orientation of this magnetic field, we introduce a new spectroscopic technique for studying dipolar quantum droplets. This provides a precise probe for interactions in the system allowing to extract a background scattering length for \textsuperscript{164}Dy of $69(4)\,a_0$. Our results establish an analogy between quantum droplets and atomic nuclei, where the existence of the scissors mode is also only due to internal interactions. They further open the possibility to explore physics beyond the available theoretical models for strongly-dipolar quantum gases.

description: Research is growing on methods to balance two competing public purposes: the need of the public for information about society and government, and the right to privacy and confidentiality of individual information. This article presents a case study in which a governmental agency (the U.S. Department of Justice) released a report (on federal capital cases, 1995--2000) seeking to conceal certain information (the recommendations of the U.S. Attorney and the DOJ Review Committee on whether to seek the death penalty), while releasing cross-tabulations of the concealed information with other, public information about the cases. Careful study of the released cross-tabulations led to full identification of all the variables in 386 out of 682 cases. Using other public data led to full identification of another 160. For the remaining 136 cases, the space of possible values for the missing data is drastically reduced. This article explains how the inferences were made.

description: Las redes sociales ofrecen multiplicidad de funcionalidades que acercan a los usuarios y, por lo tanto, les permite interactuar de una forma más directa y consecuente con sus intereses, facilitando el ejercicio de acciones concretas con consecuencias jurídicas relevantes. Es el caso del comercio electrónico, que a través de redes sociales y estratégicas campañas de publicidad, ha logrado potencializar la oferta de bienes, servicios o productos. La constante evolución de las TIC, así como las diferentes técnicas utilizadas para el análisis de información a efectos de publicidad, dejan en entredicho el correcto tratamiento de datos personales y vislumbran la pérdida del control por parte de los titulares, siendo el resultado la vulneración de derechos fundamentales y/o la causación de daños antijurídicos. La normativa especializada en Colombia es escasa, pero existen distinguidos pronunciamientos, siendo conveniente realizar un ejercicio comparativo con las directrices adoptadas por la Unión Europea –como referente– y así, exponer algunas reflexiones. A lo largo del documento, se desarrollan variados asuntos que resultan polémicos, como el caso de los influencers, la posibilidad de retribución por el uso de los datos personales, la posible responsabilidad civil que puede derivarse de un mal uso y/o análisis de datos, entre otros.
description: Social networks offer a multiplicity of functionalities that bring users closer and, therefore, allow them to interact in a more direct and consistent way with their interests, facilitating the exercise of concrete actions with relevant legal consequences. This is the case of e-commerce, which, through social networks and strategic advertising campaigns, enhances the supply of goods, services or products. The constant evolution of ICT, as well as the different techniques used for the analysis of information for advertising purposes, leave in question the correct treatment of personal data and the loss of control by the owners, resulting in the infringement of fundamental rights and/or causing unlawful damages. It is therefore essential to analyze the national regulation on the processing of data for advertising purposes, making a comparative exercise with the guidelines adopted by the European Union on the same subject. Finally, some reflections on current controversial issues are outlined, such as the possibility of remuneration for the use of personal data, the case of influencers and the civil liability that may arise from misuse and/or analysis of data.

description: Neutrinoless double-beta decay represents the most promising approach for revealing some of the most important, yet-unknown, properties of neutrinos related to their absolute masses and their nature. This transition involves beyond standard model theories that predict the violation of the lepton number conservation by two units. There is no experimental confirmation yet for this decay, but new experiments have set lower-limits for the associated half-lives in the case of several isotopes. Using an effective field theory that describes this transition, we calculate half-life ratios for five experimentally interesting isotopes in the case of 12 lepton number violating couplings. These half-life ratios can be used to probe the sensitivity of the five isotopes in relation to their respective mechanisms, to predict the half-life limits needed to match the different experimental results, and in the case of experimental confirmation, these ratios could possibly indicate the dominant mechanism of the transition. We provide an analysis that could reveal valuable information regarding the dominant neutrinoless double-beta decay mechanism, if experimental half-life data becomes available for different isotopes.

description: This paper provides an empirical analysis of the comparative evolution of interprovincial and international trade and their effects on regional growth for the Canadian provinces since 1981. Two sets of results emerge from the analysis. First, it appears that the rapid expansion of international trade following the Canada-United States Free Trade Agreement with a certain lag did not produce a decrease in interprovincial trade. To the contrary, we found a positive relation between the two trade channels, especially since 1991. Second, using a conditional convergence econometric framework, we found that increased international trade openness has a positive and significant long-run effect on regional standards of living, productivity, and employment. Increased interprovincial trade has a positive effect on GDP per capita and employment; however, the effect appears to be close to zero on labour productivity. / Commerce international, commerce interprovincial et croissance économique régionale au Canada - Dans cette étude empirique, l’auteur analyse l’évolution comparée du commerce international et du commerce interprovincial des provinces canadiennes depuis 1981. Une attention particulière est accordée à l’analyse de l’incidence de l’évolution des liens commerciaux sur la croissance économique des économies provinciales. Deux ensembles de résultats ressortent de l’analyse. En premier lieu, il apparaît que la forte expansion du commerce international qui a suivi avec un certain délai l’Accord de libre-échange canado-américain n’aurait pas entraîné une diminution du commerce interprovincial. Au contraire, l’analyse montre que, surtout depuis 1991, l’expansion du commerce Nord-Sud aurait exercé une incidence positive sur le commerce Est-Ouest. En second lieu, dans le cadre d’une régression de croissance fondée sur un modèle de convergence conditionnelle, l’expansion du commerce international aurait eu un effet de long terme significatif sur le niveau de vie, la productivité et l’emploi des économies provinciales. L’accroissement du commerce interprovincial, pour sa part, n’aurait un effet positif et significatif que sur l’emploi et le PIB par habitant. L’effet du commerce Est-Ouest sur la productivité de la main-d’oeuvre serait nul.

description: A spin-isospin dependent Three-Dimensional approach based on momentum vectors for formulation of the three-nucleon bound state is presented in this paper. The three-nucleon Faddeev equations with two-nucleon interactions are formulated as a function of vector Jacobi momenta, specifically the magnitudes of the momenta and the angle between them with the inclusion of the spin-isospin quantum numbers, without employing a partial wave decomposition. As an application the spin-isospin dependent Faddeev integral equations are solved with Bonn-B potential. Our result for the Triton binding energy with the value of -8.152 MeV is in good agreement with the achievements of the other partial wave based methods.

description: We contrast three decision rules that extend Expected Utility to contexts where a convex set of probabilities is used to depict uncertainty: Γ-Maximin, Maximality, and E-admissibility. The rules extend Expected Utility theory as they require that an option is inadmissible if there is another that carries greater expected utility for each probability in a (closed) convex set. If the convex set is a singleton, then each rule agrees with maximizing expected utility. We show that, even when the option set is convex, this pairwise comparison between acts may fail to identify those acts which are Bayes for some probability in a convex set that is not closed. This limitation affects two of the decision rules but not E-admissibility, which is not a pairwise decision rule. E-admissibility can be used to distinguish between two convex sets of probabilities that intersect all the same supporting hyperplanes.

description: Stationary and instationary Stokes and Navier-Stokes flows are considered on two-dimensional manifolds, i.e., on curved surfaces in three dimensions. The higher-order surface FEM is used for the approximation of the geometry, velocities, pressure, and Lagrange multiplier to enforce tangential velocities. Individual element orders are employed for these various fields. Stream-line upwind stabilization is employed for flows at high Reynolds numbers. Applications are presented which extend classical benchmark test cases from flat domains to general manifolds. Highly accurate solutions are obtained and higher-order convergence rates are confirmed.
