description: From a reflection measurement in a rectangular microwave billiard with randomly distributed scatterers the scattering and the ordinary fidelity was studied. The position of one of the scatterers is the perturbation parameter. Such perturbations can be considered as {\em local} since wave functions are influenced only locally, in contrast to, e. g., the situation where the fidelity decay is caused by the shift of one billiard wall. Using the random-plane-wave conjecture, an analytic expression for the fidelity decay due to the shift of one scatterer has been obtained, yielding an algebraic $1/t$ decay for long times. A perfect agreement between experiment and theory has been found, including a predicted scaling behavior concerning the dependence of the fidelity decay on the shift distance. The only free parameter has been determined independently from the variance of the level velocities.

description: En un mundo enmarcado por el ultra-capitalismo, la noción de abundancia juega un papel fundamental en nuestras sociedades ya que crea prácticas, rituales y creencias para manifestar el equilibrio social ante la carencia y la escasez. Se trata de entender la abundancia como un concepto que construye nociones de consumo y del “buen vivir” en experiencias sociales y familiares. De esta manera se buscó profundizar en la lógica del Don (Dar, Recibir y Devolver) y las lógicas mercantiles de la (Productividad, Hiperindividualismo, la sociedad del rendimiento, la cultura del dinero y la instrumentalización) Visualizadas desde la comprensión de jóvenes de clases populares de la ciudad de Bogotá. Aquí entran en juego una serie de tensiones y resistencias que condicionan las relaciones al interior de la familia que redefinen las redes de apoyo como punto de encuentro y los desacuerdos entre la lógica del Don y las lógicas mercantiles. Observamos la abundancia como constructora de vínculos familiares que puede ayudar a crear nociones contrahegemónicas sobre cómo podríamos encaminar nuestras relaciones vinculares fuera del ultra-capitalismo que nos conduce cada vez más a la disolución de las redes de apoyo comunitarias.
description: In a world framed by ultra-capitalism, the notion of abundance plays a fundamental role in our societies as it creates practices, rituals and beliefs to manifest social balance in the face of lack and scarcity. It is about understanding abundance as a concept that builds notions of consumición and “good living" in social and family experiences. In this way, we sought to deepen the logic of the Gift (Give, Receive and Return) and the mercantile logics of (Productivity, Hyperindividualism, the society of performance, the culture of money and instrumentalization) Visualized from the understanding of young people of popular classes of the city of Bogota. At stake here are a series of tensions and resistances that condition relations within the family that redefine support networks as a meeting point and disagreements between the logic of the Gift and mercantile logics. We look at abundance as a builder of family bonds that can help create counter-hegemonic notions about how we could direct our bonding relationships outside of ultra-capitalism that increasingly leads to the dissolution of community support networks.

Thermoelectric DC conductivities in hyperscaling violating Lifshitz theories

description: We analytically compute the thermoelectric conductivities at zero frequency (DC) in the holographic dual of a four dimensional Einstein-Maxwell-Axion-Dilaton theory that admits a class of asymptotically hyperscaling violating Lifshitz backgrounds with a dynamical exponent $z$ and hyperscaling violating parameter $θ$. We show that the heat current in the dual Lifshitz theory involves the energy flux, which is an irrelevant operator for $z>1$. The linearized fluctuations relevant for computing the thermoelectric conductivities turn on a source for this irrelevant operator, leading to several novel and non-trivial aspects in the holographic renormalization procedure and the identification of the physical observables in the dual theory. Moreover, imposing Dirichlet or Neumann boundary conditions on the spatial components of one of the two Maxwell fields present leads to different thermoelectric conductivities. Dirichlet boundary conditions reproduce the thermoelectric DC conductivities obtained from the near horizon analysis of Donos and Gauntlett, while Neumann boundary conditions result in a new set of DC conductivities. We make preliminary analytical estimates for the temperature behavior of the thermoelectric matrix in appropriate regions of parameter space. In particular, at large temperatures we find that the only case which could lead to a linear resistivity $ρ\sim T$ corresponds to $z=4/3$.

description: This report describes an extension to the C programming language to introduce the notion of ranged integers, that is, integer types with a defined range of values. A variable of a ranged integer type will always have a value within the defined range as a result of initialization or assignment. Use of ranged integers would help prevent integer overflow errors and thus would result in more reliable and secure C programs. The syntax and semantics of ranged integers are presented, and some examples are given to illustrate their use.
The Palatini side of inflationary attractors

description: We perform an analysis of models of chaotic inflation where the inflaton field $ϕ$ is coupled non-minimally to gravity via $ξϕ^n g^{μν}R_{μν}(Γ), n>0$. We focus on the Palatini theory of gravity, i.e. the case where the assumptions of the General Relativity are relaxed (that of the connection being the Levi-Civita one) and the gravitational degrees of freedom are encoded not only in the metric but also the connection $Γ$, which is treated as an independent variable. We show that in this case the famous attractor behaviour of simple non-minimally coupled models of inflation is lost. Therefore the attractors are not universal but their existence depends on the underlying theory of gravity in a subtle way. We discuss what this means for chaotic models and their observational consequences.

description: We characterize the spatial density of the Pan-STARRS1 (PS1) sample of RR Lyrae stars, to study the properties of the old Galactic stellar halo as traced by RRab stars. This sample of 44,403 sources spans Galactocentric radii of $0.55 \; \mathrm{kpc} \leq R_{\mathrm{gc}} \leq 141 \; \mathrm{kpc}$ with a distance precision of 3\% and thus is able to trace the halo out to larger distances than most previous studies. After excising stars that are attributed to dense regions such as stellar streams, the Galactic disc and bulge as well as halo globular clusters, the sample contains ${\sim}11,000$ sources within $20 \; \mathrm{kpc} \leq R_{\mathrm{gc}} \leq 131 \; \mathrm{kpc}$. We then apply forward modeling using ellipsoidal stellar density models $ρ(l,b,R_{\mathrm{gc}})$ both with a constant and a radius-dependent halo flattening $q(R_{\mathrm{gc}})$. Assuming constant flattening $q$, the distribution of the sources is reasonably well fit from $20 \; \mathrm{kpc}$ to $131 \; \mathrm{kpc}$ by a single power law with $n=4.40^{+0.05}_{-0.04}$ and $q=0.918^{+0.016}_{-0.014}$. The distance distribution is fit comparably well by an Einasto profile with $n=9.53^{+0.27}_{-0.28}$, an effective radius $r_{\mathrm{eff}}=1.07 \pm 0.10 \; \mathrm{kpc}$ and a halo flattening of $q=0.923 \pm 0.007$. If we allow for a radius-dependent flattening $q(R_{\mathrm{gc}})$, we find evidence for a distinct flattening of $q{\sim}0.8$ of the inner halo at ${\sim} 25 \; \mathrm{kpc}$. Additionally, we find that the south Galactic hemisphere is more flattened than the north Galactic hemisphere. The results of our work are largely consistent with many earlier results, e.g. \cite{Watkins2009}, \cite{Iorio2017}. We find that the stellar halo, as traced in RR Lyrae stars, exhibits a substantial number of further significant over- and underdensities, even after all known overdensities have been masked.

description: En el presente artículo se realiza un análisis de algunos elementos del desarrollo sustentable bajo una visión holística que pretende afrontar el escenario de crisis ambiental actual. Se dedica un primer capítulo a exponer las ideas del desarrollo desde una perspectiva no convencional, incorporando elementos de la economía ecológica como una opción que integra la sustentabilidad ambiental en las decisiones económicas, junto con el concepto de la ecología política, que examina la interacción entre el poder político, las prácticas económicas y su impacto en el medio ambiente y en la sociedad. Las ideas del decrecimiento y desacoplamiento, toman relevancia ante la finitud de los recursos naturales. En el segundo capítulo, se destaca la relevancia de la gobernanza ambiental en la búsqueda de un futuro equilibrado y próspero para la sociedad, ante desafíos ambientales como el cambio climático, la pérdida de biodiversidad y la degradación de suelos. Finalmente, en el tercer capítulo, se analiza un ejemplo específico en México que ilustra la ausencia de gobernanza ambiental y una evidente violación de los derechos humanos, lo cual refleja un retroceso en la protección ambiental.
description: The first chapter is dedicated to presenting the ideas of development from a non-conventional perspective, incorporating elements of ecological economics as an option that integrates environmental sustainability into economic decisions, along with the concept of political ecology, which examines the interaction between political power, economic practices, and their impact on the environment and society. The ideas of degrowth and decoupling gain relevance in the face of the finitude of natural resources. In the second chapter, the relevance of environmental governance is highlighted in the pursuit of a balanced and prosperous future for society, in the face of environmental challenges such as climate change, biodiversity loss, and soil degradation. Finally, in the third chapter, a specific example in Mexico is examined that illustrates the absence of environmental governance and an evident violation of human rights, reflecting a regression in environmental protection.
Radical Improvements Require Radical Actions: Simulating a High- Maturity Software Organization
Creators: name: Burke, Steven
Publisher: name: Carnegie Mellon University
Year: 1997
Subjects: subject: 80309 Software Engineering
subject: FOS: Computer and information sciences

description: This report describes the methodology used to create a simulation of a high-maturity software organization and the results of that simulation. The goal of this research was to find the quantitative value of improving from the Capability Maturity Model (CMM) Level 3 to Level 5. The method was to simulate a high-maturity organization using its actual empirical data and then "cut out" the high-maturity elements of the simulation. The resulting change in software size, effort, schedule, and quality would be a more accurate measure of the value of high maturity than working forward with a low- or medium-maturity organization and merely hypothesizing the activities and values of high maturity. The author used computer simulations based on systems thinking and systems dynamics, which reasonably modeled the "soft variables" of the people aspects of an organization (personnel attitudes, learning curve, participation in software process improvement, etc.). The simulation also related the soft variables to the hard variables of a software organization's life-cycle process (software size, effort, schedule, quality, etc.).
Topological Hall effect in diffusive ferromagnetic thin films with spin-flip scattering

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study the topological Hall effect in a diffusive ferromagnetic metal thin film by solving a Boltzmann transport equation in the presence of spin-flip scattering. A generalized spin diffusion equation is derived, which contains an additional source term associated with the gradient of the emergent magnetic field that arises, and its solution shows that spin accumulation may build up in the vicinity of the magnetic skyrmions. We show that the spin accumulation gives rise to a spin polarized diffusion current that in general suppresses that bulk topological Hall current. Only when the spin diffusion length is much smaller than the skyrmion size, the topological Hall resistivity approaches to the one originally derived by Bruno \textit{et al.} [Phys. Rev. Lett. \textbf{93}, 096806 (2004)]. We derive a general expression of the TH resistivity that applies to thin-film geometries with spin-flip scattering, and show that the corrections to the TH resistivity become large when the size of room temperature skyrmions is further reduced to tens of nanometers.

description: This research investigates the emergence of neutrinos from quantum instability, examining the role of dark matter as a stabilizing force in multi-dimensional quantum systems. By integrating Vesica Piscis-Enhanced Quantum Fourier Transform (VP-QFT), recursive tensor expansions, and Dark Matter Quantum Perimeter Function (DMQPF) corrections, we establish a new framework for understanding neutrino oscillations as a function of quantum tunneling events. Theoretical models are validated against LIGO data, revealing a distinct 400-500 Hz frequency band associated with quantum instability, correlating with observed neutrino behavior. This study provides strong evidence for the existence of a structured energy balance between quanta emergence and dark matter fields.
Quantum optical realization of arbitrary linear transformations allowing for loss and gain

description: Unitary transformations are routinely modeled and implemented in the field of quantum optics. In contrast, nonunitary transformations that can involve loss and gain require a different approach. In this theory work, we present a universal method to deal with nonunitary networks. An input to the method is an arbitrary linear transformation matrix of optical modes that does not need to adhere to bosonic commutation relations. The method constructs a transformation that includes the network of interest and accounts for full quantum optical effects related to loss and gain. Furthermore, through a decomposition in terms of simple building blocks it provides a step-by-step implementation recipe, in a manner similar to the decomposition by Reck et al. [Reck et al., Phys. Rev. Lett. 73, 58 (1994)] but applicable to nonunitary transformations. Applications of the method include the implementation of positive-operator-valued measures and the design of probabilistic optical quantum information protocols.

Year: 2025

description: This research investigates the quantum optical properties of dark matter and its ability to influence the propagation of electromagnetic waves. Using simulated models of dark matter filaments, we analyze how dark matter bends, delays, and guides X-rays, radio waves, and visible light. Our results confirm that dark matter can create structured pathways for photons, mimicking optical fiber-like behavior. Furthermore, we provide evidence that dark matter is responsible for unexplained fast radio burst (FRB) multiplicities and gravitational lensing anomalies. The implications suggest that dark matter is not merely an invisible mass but an active quantum medium that structures cosmic light pathways.

description: When attempting to develop wavelet transforms for graphs and networks, some researchers have used graph Laplacian eigenvalues and eigenvectors in place of the frequencies and complex exponentials in the Fourier theory for regular lattices in the Euclidean domains. This viewpoint, however, has a fundamental flaw: on a general graph, the Laplacian eigenvalues cannot be interpreted as the frequencies of the corresponding eigenvectors. In this paper, we discuss this important problem further and propose a new method to organize those eigenvectors by defining and measuring "natural" distances between eigenvectors using the Ramified Optimal Transport Theory followed by embedding them into a low-dimensional Euclidean domain. We demonstrate its effectiveness using a synthetic graph as well as a dendritic tree of a retinal ganglion cell of a mouse.

description: This study introduces a predictive framework for neutrino bursts associated with high-spin gravitational wave events, specifically GW170817, GW190521, and GW200129. Using the Vesica Piscis-Enhanced Quantum Fourier Transform (VP-QFT) and Schwarzschild entropy fluctuation analysis, we establish a direct link between gravitational wave oscillations, neutrino bursts, and quantum teleportation frequencies. Our results indicate that neutron star mergers exhibit delayed neutrino bursts, while black hole mergers generate near-instantaneous emissions. This discovery enables real-time alerts for IceCube, KM3NeT, and other neutrino observatories, revolutionizing multi-messenger astrophysics.

description: Esta tesis pretende demostrar las diferentes implicaciones que conlleva la aplicación de los conceptos del mínimo vital de energía y la pobreza energética en el ordenamiento jurídico colombiano, enfatizándose en las modificaciones que podrían generarse en algunas obligaciones generales establecidas en la legislación y en la regulación de los contratos de prestación del servicio de energía eléctrica. Para tales propósitos, se parte del análisis a partir de estas nociones fundamentales, como lo son que la pobreza energética y el mínimo vital de energía han evolucionado tanto en la jurisprudencia como en otras fuentes jurídicas hasta tener aplicación. Otra de las ideas radica en el estudio de la naturaleza del contrato de prestación de servicios, a fin de poder constatar los efectos que conllevan en tal negocio jurídico la aplicación de los conceptos estudiados. Con lo anterior, se logra concluir la relevancia del estudio del mínimo vital de energía y de la pobreza energética en cuanto a que su aplicación en el ordenamiento jurídico colombiano tiene impactos en las principales obligaciones del contrato de prestación de servicios, tanto en su parte pre-contractual como en alguna de sus obligaciones contractuales.
description: This thesis aims to demonstrate the different implications that arise from the application of the concepts of "vital minimum of energy" and "full poverty" in the Colombian legal system, emphasizing the modifications that could be generated in some general obligations established in the legislation and in the regulation of the electricity service provision contracts. For such purposes, the analysis is based on these fundamental notions, such as that full poverty and the vital minimum of energy have evolved both in jurisprudence and in other legal sources until they have been applied. Another idea lies in the study of the nature of the contract for the provision of services, in order to be able to verify the effects that the application of the concepts studied entails in such a legal transaction. With the above, it is possible to conclude the relevance of the study of the vital minimum of energy and full poverty in that its application in the Colombian legal system has impacts on the main obligations of the contract for the provision of services, both in its pre-contractual part as in any of its contractual obligations.

description: The time fractional diffusion equation is obtained from the standard diffusion equation by replacing the first-order time derivative with a fractional derivative of order $β\in (0,1)$. The fundamental solution for the Cauchy problem is interpreted as a probability density of a self-similar non-Markovian stochastic process related to a phenomenon of sub-diffusion (the variance grows in time sub-linearly). A further generalization is obtained by considering a continuous or discrete distribution of fractional time derivatives of order less than one. Then the fundamental solution is still a probability density of a non-Markovian process that, however, is no longer self-similar but exhibits a corresponding distribution of time-scales.

description: We investigate the carrier-envelope phase and intensity dependence of the longitudinal momentum distribution of photoelectrons resulting from above-threshold ionization of argon by few-cycle laser pulses. The intensity of the pulses with a center wavelength of 750\,nm is varied in a range between $0.7 \times 10^{14}$ and $\unit[5.5 \times 10^{14}]{W/cm^2}$. Our measurements reveal a prominent maximum in the carrier-envelope phase-dependent asymmetry at photoelectron energies of 2\,$U_\mathrm{P}$ ($U_\mathrm{P}$ being the ponderomotive potential), that is persistent over the entire intensity range. Further local maxima are observed at 0.3 and 0.8\,$U_\mathrm{P}$. The experimental results are in good agreement with theoretical results obtained by solving the three-dimensional time-dependent Schrödinger equation (3D TDSE). We show that for few-cycle pulses, the carrier-envelope phase-dependent asymmetry amplitude provides a reliable measure for the peak intensity on target. Moreover, the measured asymmetry amplitude exhibits an intensity-dependent interference structure at low photoelectron energy, which could be used to benchmark model potentials for complex atoms.

description: While deep learning models become more widespread, their ability to handle unseen data and generalize for any scenario is yet to be challenged. In medical imaging, there is a high heterogeneity of distributions among images based on the equipment that generates them and their parametrization. This heterogeneity triggers a common issue in machine learning called domain shift, which represents the difference between the training data distribution and the distribution of where a model is employed. A high domain shift tends to implicate in a poor generalization performance from the models. In this work, we evaluate the extent of domain shift on four of the largest datasets of chest radiographs. We show how training and testing with different datasets (e.g., training in ChestX-ray14 and testing in CheXpert) drastically affects model performance, posing a big question over the reliability of deep learning models trained on public datasets. We also show that models trained on CheXpert and MIMIC-CXR generalize better to other datasets.

description: This handbook documents the QUASAR (QUality Assessment of System ARchitectures) method for assessing the quality of the architecture of a software-intensive system. It begins by discussing the challenges that are faced when assessing a system's architecture and outlines the development history of the method. The next section of the handbook documents the concept of quality cases and the claims, arguments, and evidence that compose them. This is followed by a description of the teams that collaborate to perform QUASAR tasks. Next, individual tasks and associated steps performed as part of the QUASAR method are documented. Next, the work products produced by these teams when performing these tasks are described. Finally, lessons learned during the development and use of the method when assessing the quality of major subsystems during the development of a very large, software-intensive system of systems are presented. Also provided are appendices that define common quality factors and subfactors, offer reusable checklists, and give examples of quality cases. The example quality cases illustrate valid quality goals and requirements that compose claims, example architecture decisions and associated rationales that compose arguments, and the types of evidence that architects might provide.

description: Dans sa dimension externe, l’indépendance judiciaire a traditionnellement été conçue en rapport avec les autres branches de l’État, les pouvoirs législatif et exécutif. Sur la base d’entretiens qualitatifs et dans le contexte spécifique de la détermination de la peine, cet article explore les contours de l’indépendance judiciaire par rapport à ce que les acteurs judiciaires peuvent considérer comme des menaces externes à leur liberté décisionnelle, menaces dépassant pour eux le cadre plus traditionnel de ce qui relève strictement de l’État. L’objectif que nous nous sommes fixé est d’offrir une perspective à la fois plus contemporaine et élargie des conditions susceptibles de favoriser la pleine protection de la zone de liberté décisionnelle qu’exige l’indépendance judiciaire. Cela nous a amenés à problématiser les menaces externes qui, sans être nécessairement étatiques, peuvent néanmoins compromettre, de l’extérieur, l’intégrité de la détermination de la peine. Nous nous sommes plus particulièrement intéressés aux menaces que représentent, dans ce contexte, les peines minimales obligatoires, celles émanant de la pression médiatique, de l’opinion publique et des demandes adressées au système pénal par les mouvements sociaux. In its external dimension, judicial independence has traditionally been conceived only in relation to the two other branches of the State, the legislative and the executive. On the basis of qualitative interviews and in the specific context of sentencing, this article explores the contours of judicial independence and of the possible external threats to the decisional freedom of judicial actors, threats whose origin is located not only inside but also outside the traditional state powers. The objective we have set ourselves in this study is to offer a more contemporary and enlarged perspective on the conditions that favour the full protection of the area of freedom in decision-making, the one that a strong concept of judicial independence demands. This has led us to problematize the external threats that compromise the integrity of sentencing system. In particular, we have focused on the political threats posed by mandatory minimum sentences, those arising from media pressure, from the so-called “public opinion” or from the demands that some social movements address to the criminal law system.
QuARS: A Tool for Analyzing Requirements

description: Numerous tools and techniques are available for managing requirements. Many are designed to define requirements, provide configuration management, and control distribution. However, there are few automatic tools to support the quality analysis of natural language (NL) requirements. Ambiguity analysis and consistency and completeness verification are usually carried out by human reviewers who read requirements documents and look for defects. This clerical activity is boring, time consuming, and often ineffective. This report describes a disciplined method and a related automated tool that can be used for the analysis of NL requirements documents. The tool, called the Quality Analyzer for Requirements Specifications (QuARS), makes it easier to extract structured information and metrics for detecting linguistic inaccuracies and defects. QuARS allows requirements engineers to perform an initial parsing of requirements by automatically detecting potential linguistic defects that can cause ambiguity problems at later stages of software product development. The tool also provides support for the consistency and completeness analysis of the requirements.

description: Inflationary observables, like the power spectrum, computed at one- and higher-order loop level seem to be plagued by large infra-red corrections. In this short note, we point out that these large infra-red corrections appear only in quantities which are not directly observable. This is in agreement with general expectations concerning infra-red effects.

What and Whence 1I/`Oumuamua: A Contact Binary from the Debris of a Young Planetary System?

description: The first confirmed interstellar interloper in our Solar System, 1I/`Oumuamua, is likely to be a minor body ejected from another star, but its brief flyby and faintness made it difficult to study. Two remarkable properties are its large (up to 2.5 mag) rotational variability and its motion relative to the Sun before encounter. The former suggests an extremely elongated shape (aspect ratio ~10) and the latter an origin from the protoplanetary disk of a young star in a nearby association. Against expectations, it is also not comet-like. 1I/`Oumuamua's variability can also be explained if it is a contact binary composed of near-equilibrium ellipsoidal components and heterogeneous surfaces, i.e. brighter, dust-mantled inner-facing hemispheres and darker, dust-free outer-facing poles. Such shapes are a plausible outcome of radiation, tides and collisions in systems where planets are clearing planetesimal disks. The probability that 1I/`Oumuamua has the same motion as a young (

Dark energy as a mirage

description: Motivated by the observed cosmic matter distribution, we present the following conjecture: due to the formation of voids and opaque structures, the average matter density on the path of the light from the well-observed objects changes from Omega_M ~ 1 in the homogeneous early universe to Omega_M ~ 0 in the clumpy late universe, so that the average expansion rate increases along our line of sight from EdS expansion Ht ~ 2/3 at high redshifts to free expansion Ht ~ 1 at low redshifts. To calculate the modified observable distance-redshift relations, we introduce a generalized Dyer-Roeder method that allows for two crucial physical properties of the universe: inhomogeneities in the expansion rate and the growth of the nonlinear structures. By treating the transition redshift to the void-dominated era as a free parameter, we find a phenomenological fit to the observations from the CMB anisotropy, the position of the baryon oscillation peak, the magnitude-redshift relations of type Ia supernovae, the local Hubble flow and the nucleosynthesis, resulting in a concordant model of the universe with 90% dark matter, 10% baryons, no dark energy, 15 Gyr as the age of the universe and a natural value for the transition redshift z_0=0.35. Unlike a large local void, the model respects the cosmological principle, further offering an explanation for the late onset of the perceived acceleration as a consequence of the forming nonlinear structures. Additional tests, such as quantitative predictions for angular deviations due to an anisotropic void distribution and a theoretical derivation of the model, can vindicate or falsify the interpretation that light propagation in voids is responsible for the perceived acceleration.
