En el presente artículo nos proponemos analizar uno de los componentes fundamentales de la experiencia del usuario en interacción con escenarios inmersivos o de realidad virtual: la ilusión de presencia. Se trata de la sensación de estar presente en el escenario virtual, con plena consciencia de no estar realmente allí. Se realiza un recorrido teórico por la historia del concepto para llegar a una definición integral del mismo, se detallan las características que debe cumplir un diseño inmersivo para favorecer la ilusión de presencia del usuario y, finalmente, se analiza el caso de la serie Punto de Quiebre, primera producción 360 de Argentina, como ejemplo práctico de los parámetros indicados anteriormente.

The statistics community, which has traditionally lacked a transparent and open peer-review system, faces a challenge of inconsistent paper quality, with some published work containing substantial errors. This problem resonates with concerns raised by Schaeffer et al. (2025) regarding the rapid growth of machine learning research. They argue that peer review has proven insufficient to prevent the publication of ``misleading, incorrect, flawed or perhaps even fraudulent studies'' and that a ``dynamic self-correcting research ecosystem'' is needed. This note provides a concrete illustration of this problem by examining two published papers, Wang, Zhou and Lin (2025) and Liu et al. (2023), and exposing striking and critical errors in their proofs. The presence of such errors in major journals raises a fundamental question about the importance and verification of mathematical proofs in our field. Echoing the proposal from Schaeffer et al. (2025), we argue that reforming the peer-review system itself is likely impractical. Instead, we propose a more viable path forward: the creation of a high-profile, reputable platform, such as a ``Refutations and Critiques'' track on arXiv, to provide visibility to vital research that critically challenges prior work. Such a mechanism would be crucial for enhancing the reliability and credibility of statistical research.

Understanding the changing structure of science over time is essential to elucidating how science evolves. We develop diachronic embeddings of scholarly periodicals to quantify "semantic changes" of periodicals across decades, allowing us to track the evolution of research topics and identify rapidly developing fields. By mapping periodicals within a physical-life-health triangle, we reveal an evolving interdisciplinary science landscape, finding an overall trend toward specialization for most periodicals but increasing interdisciplinarity for bioscience periodicals. Analyzing a periodical's trajectory within this triangle over time allows us to visualize how its research focus shifts. Furthermore, by monitoring the formation of local clusters of periodicals, we can identify emerging research topics such as AIDS research and nanotechnology in the 1980s. Our work offers novel quantification in the science of science and provides a quantitative lens to examine the evolution of science, which may facilitate future investigations into the emergence and development of research fields.

Plakat jest jedną z form graficznej sztuki użytkowej, której zasadniczym celem jest propagowanie lub popularyzowanie, informowanie o różnorodnych sferach życia społecznego. Każda dziedzina aktywności człowieka posiada plakaty jej dotyczące. Nie inaczej sytuacja przedstawia się w przypadku prasy codziennej (dzienników), jak również innych wydawnictw periodycznych, takich jak tygodniki, miesięczniki itp. Plakaty, czyli tzw. „sztuka ulicy”, powstawały na zamówienie wydawnictw prasowych czy też poszczególnych redakcji. W kontekście szeroko rozumianej prasy plakaty ją reklamujące, propagujące nabierają szczególnego znaczenia. Z samego założenia prasa, zwłaszcza ta codzienna, sama w sobie stanowi element propagandy, czy to państwowej, czyli rządowej, czy też np. partyjnej. Niemal identyczne założenie przyświeca plakatom. Znajdująca się w warszawskim Muzeum Niepodległości kolekcja plakatów, która stanowi podstawę niniejszego opracowania, liczy ponad 8000 pozycji. W tym zbiorze prace dotyczące interesującego nas tematu to 125 tytułów. Powstały one na przestrzeni ponad 40 lat. Najstarszy pochodzi z roku 1948, a ostatni, czyli najmłodszy, powstał w 1989 roku. Tak znaczną liczbę oraz rozpiętość czasową w zakresie ich powstawania można uznać za reprezentatywną dla całości tego zagadnienia. Należy również zwrócić uwagę na fakt, że wiele spośród nich powstało w pracowniach najlepszych polskich grafików. Wśród nich nie zabrakło tych najbardziej znamienitych, zaliczanych do twórców i kontynuatorów tzw. Polskiej Szkoły Plakatu. Przygotowane opracowanie niewątpliwie nie wyczerpuje tematu, jednak może ono stanowić punkt wyjścia do dalszych badań i analiz tego zagadnienia. Do chwili obecnej ta grupa tematyczna w zakresie sztuki plakatu była najczęściej umiejscawiana w grupie plakatów społeczno-politycznych. Nadszedł chyba jednak czas, by ten zakres tematyczny doczekał się własnych opracowań monograficznych.

Este estudio analiza la comunicación institucional durante la pandemia de COVID-19 y las estrategias que utilizaron diferentes gobiernos, organizaciones no gubernamentales y medios de comunicación para educar, generar confianza y enfrentar los retos comunicativos en una situación de crisis. Además, se examinan las lecciones aprendidas a lo largo de la pandemia y su impacto en la percepción pública y la difusión efectiva de información relevante. La metodología empleada en este artículo consistió en realizar una búsqueda sistemática y exhaustiva de fuentes académicas, casos prácticos y documentos oficiales sobre el tema en diversas bases de datos, repositorios digitales y notas de prensa. Para llevar a cabo la revisión de literatura se implementaron estrategias de búsqueda específicas en cada base de datos y se aplicaron filtros para limitar los resultados a estudios relevantes, utilizando palabras clave relacionadas con el tema de investigación y criterios de inclusión precisos seleccionando recursos publicados en los últimos cinco años y en los idiomas español e inglés. Los principales hallazgos revelaron que la efectividad en la comunicación de los Gobiernos y los medios de comunicación durante la crisis de COVID-19 se fundamentó en la transparencia, la participación ciudadana, la empatía, la colaboración con expertos y la adaptabilidad. Estos factores fueron fundamentales para generar confianza, credibilidad y apoyo hacia las instituciones. En última instancia, esta investigación proporciona una perspectiva integral sobre las estrategias de comunicación institucional empleadas durante la emergencia sanitaria causada por la crisis del coronavirus, resaltando la importancia crítica de la comunicación efectiva en la gestión de crisis.

Este estudio traza un mapa del uso periodístico de la inteligencia artificial (IA) en España. Para ello se envió un cuestionario a cien medios de comunicación. Las respuestas obtenidas (88) permiten asegurar que el 60 % de los medios usa IA, sobre todo para distribución de información o relación con la audiencia y recogida automatizada de información. La producción automatizada de textos sigue siendo escasa. El desarrollo de la IA comenzó en España en 2017 y 2018 y se intensificó a finales de 2022 y comienzos de 2023. Actualmente, casi el 75 % de los periodistas encuestados tiene una opinión positiva o muy positiva de ella. Además, se han realizado entrevistas a cinco responsables de empresas proveedoras de servicios con IA, que también advierten una creciente aceptación de los algoritmos por los medios: del rechazo o el miedo se ha pasado a percibirlos más como una oportunidad que como un peligro.

Reactive single-step hot-pressing at 1473 K and 35 MPa for 4 h produces dense, bulk, near single-phase, low-cost and low-criticality Fe$_2$Al$_{1.15}$B$_2$ and Fe$_2$Al$_{1.1}$B$_2$Ge$_{0.05}$Ga$_{0.05}$ MAB samples, showing a second-order magnetic phase transition with favorable magnetocaloric properties around room temperature. The magnetic as well as magnetocaloric properties can be tailored upon Ge and Ga doping, leading to an increase of Curie temperature $T_C$ and spontaneous magnetization $m_S$. The maximum isothermal entropy change $Δs_{T,max}$ of hot-pressed Fe$_2$Al$_{1.15}$B$_2$ in magnetic field changes of 2 and 5 T amounts to 2.5 and 5 J(kgK)$^{-1}$ at 287.5 K and increases by Ge and Ga addition to 3.1 and 6.2 J(kgK)$^{-1}$ at 306.5 K, respectively. The directly measured maximum adiabatic temperature change $ΔT_{ad,max}$ is improved by the composition modification from 0.9 to 1.1 K in magnetic field changes of 1.93 T. Overall, we demonstrate that hot-pressing provides a much faster, more scalable and processing cost reducing alternative compared to conventional synthesis routes to produce heat exchangers for magnetic cooling devices. Therefore, our criticality assessment shows that hot-pressed Fe-based MAB phases provide a promising compromise of material and processing cost, criticality and magnetocaloric performance, demonstrating the potential for low-cost and low-criticality magnetocaloric applications around room temperature.

The ratio of the total number of citations to the total number of cited papers was predicted as a constant by Garfield. But, later he observed the changing nature of this constant over time. Scientometricians thus preferred to call it Garfield Ratio rather than Garfield Constant. The Garfield Ratio is a very well-known citation-based parameter, which actually indicates the average citation per cited article. However, Garfield still pointed out that behind this ratio some deeper regularity may be found. In this paper, an analysis of this indicator, the Garfield Ratio is attempted for twelve distinguished Indian science journals over twelve years time span ranging from 2009 to 2020.

It has been shown that ultrasonic techniques work well for online measuring of circumferential oil film thickness profile in journal bearings; unfortunately, they can be limited by their measuring range and unable to capture details of the film all around the bearing circumference. Attempts to model the film thickness over the full range of the bearing rely on deterministic approaches, which assume the observations to be true with absolute certainty. Unaccounted uncertainties of the film thickness may lead to a cascade of inaccurate predictions for subsequent calculations of hydrodynamic parameters. In the present work, a probabilistic framework is proposed to model the film thickness with Gaussian Processes. The results are then used to estimate the location of the bearing shaft under various operational conditions. A further step in the process involves using the newly-constructed dataset to generate likelihood maps displaying the probable location of the shaft centre, given the bearing rotational speed and applied static load. The results offer the possibility to visualise the confidence of the predictions and allow the true location to be found within an area of high probability within the bearing's bore.

In this article, we present {\it GenderedNews} (\url{https://gendered-news.imag.fr}), an online dashboard which gives weekly measures of gender imbalance in French online press. We use Natural Language Processing (NLP) methods to quantify gender inequalities in the media, in the wake of global projects like the Global Media Monitoring Project. Such projects are instrumental in highlighting gender imbalance in the media and its very slow evolution. However, their generalisation is limited by their sampling and cost in terms of time, data and staff. Automation allows us to offer complementary measures to quantify inequalities in gender representation. We understand representation as the presence and distribution of men and women mentioned and quoted in the news -- as opposed to representation as stereotypification. In this paper, we first review different means adopted by previous studies on gender inequality in the media : qualitative content analysis, quantitative content analysis and computational methods. We then detail the methods adopted by {\it GenderedNews} and the two metrics implemented: the masculinity rate of mentions and the proportion of men quoted in online news. We describe the data collected daily (seven main titles of French online news media) and the methodology behind our metrics, as well as a few visualisations. We finally propose to illustrate possible analysis of our data by conducting an in-depth observation of a sample of two months of our database.

We propose a universal quantum circuit design that can estimate any arbitrary one-dimensional periodic functions based on the corresponding Fourier expansion. The quantum circuit contains N-qubits to store the information on the different N-Fourier components and $M+2$ auxiliary qubits with $M = \lceil{\log_2{N}}\rceil$ for control operations. The desired output will be measured in the last qubit $q_N$ with a time complexity of the computation of $O(N^2\lceil \log_2N\rceil^2)$. We illustrate the approach by constructing the quantum circuit for the square wave function with accurate results obtained by direct simulations using the IBM-QASM simulator. The approach is general and can be applied to any arbitrary periodic function.

In this article we consider the existence of a family of doubly-symmetric periodic orbits in the spatial circular Hill's lunar problem, in which the secondary primary at the origin is oblate. The existence is shown by applying a fixed point theorem to the equations with periodical conditions expressed in Poincare-Delaunay elements for the double symmetries after eliminating the short periodic effects in the first-order perturbations of the approximated system.

The development of functions of real variables in Taylor and Frobenius series (whole series which are formed in nonorthogonal, nonperiodic bases), in sinusoidal Fourier series (bases of orthogonal, periodic functions), in series of special functions (bases of orthogonal, nonperiodic functions), etc. is a commonly used method for solving a wide range of ordinary differential equations (ODEs) and partial differential equations (PDEs).In this article, based on an in-depth analysis of the properties of periodic sinusoidal Fourier series (SFS), we will be able to apply this procedure to a much broader category of ODEs (all linear, homogeneous and non-homogeneous equations with constant coefficients, a large category of linear and non-linear equations with variable coefficients, systems of ODEs, integro-differential equations, etc.). We will also extend this procedure and we use it to solve certain ODEs, on non-orthogonal periodic bases, represented by non sinusoidal periodic Fourier series (SFN).

For the KdV-Burgers equations for cylindrical and spherical waves the development of a regular profile starting from an equilibrium under a periodic perturbation at the boundary is studied. The equation describes a medium which is both dissipative and dispersive. For an appropriate combination of dispersion and dissipation the asymptotic profile looks like a periodical chain of shock fronts with a decreasing amplitude (sawtooth waves). The development of such a profile is preceded by a head shock of a constant height and equal velocity which depends on spatial dimension as well as on integral characteristics of boundary condition; an explicit asymptotic for this head shock is found.

While the business models used in most segments of the media industry have been profoundly changed by the Internet surprisingly little has been changed in the publishing of scholarly peer reviewed journals. Electronic delivery has become the norm, but the same publishers as before are dominating the market, selling content to subscribers. This article asks the question why Open Access (OA) to the output of mainly publicly funded research hasn't yet become the mainstream business model. OA implies a reversal of business logic from readers paying for content to authors paying fro dissemination via universa free access. The current situation is analyzed using Porter's five forces model. The analysis demonstrates a lack of competitive pressure in this industry, leading to so high profit levels of the leading publishers that they have yet to feel a strong need to change the way they operate.

Türk Sineması günümüze kadar tarihsel olarak çeşitli dönemlerden geçerek değişim ve gelişim gösterir. Bu değişim ve gelişimlerde ana unsurlardan biri de dış kaynaklı yapımlar ve uyarlamalardır. Özellikle Hollywood bütün dünya gibi Türk Sineması’nı derinden etkiler. Hollywood’un ilk yıllarında hakim olan yapı yıldız oyuncu/star sistemidir.Türk Sinema tarihi incelendiğinde de özellikle Yeşilçam dönemi olarak adlandırılan 1960-1975 yılları arasında yıldız oyuncu/star sisteminin baskın olduğu ortaya çıkmaktadır. Bununla birlikte “çocuk yıldız” oyuncular da Yeşilçam döneminde seyirciden ilgi görmüştür. Diğer yandan Ertem Eğilmez’in Canım Kardeşim (1973) filmi çekildiği dönemde gişede başarısız olsa da yıllar içinde Türk Sineması’nda önemli bir yer edinmiş ve film “çocuk yıldızlı” filmler kategorisinde değerlendirilmiştir. Çalışmada 1960-1975 yılları arasında Türk Sineması’nda önemli bir olgu olarak yer alan “çocuk yıldızlı filmler” ile Eğilmez’in Canım Kardeşim filmi karşılaştırmalı olarak analiz edilecektir. Araştırmada yöntem olarak niteliksel film analizinden yararlanılacaktır. Bu bağlamda çocuk yıldızlı filmlerin ayrı ayrı anlatılarında ve karakter özelliklerinde tekrar eden olgular belirlenecek daha sonra da bu tekrar eden olguların Canım Kardeşim filminde olup olmadığı ortaya konmaya çalışılacaktır.

With drone journalism it is possible to obtain aerial images in situations that are difficult to cover, with perspective, speed, mobility, greater safety for journalists, and at a lower cost. In this paper, an attempt is made to analyse the opportunities offered by the use of drones for news production in Spain, where an emerging industry has been detected. This is followed by a debate on the circumstances and causes behind their slow incorporation into newsroom routines, such as the cost of investing in a technology with a short lifetime due to its constant evolution and high accident rates, the technical and administrative complexity involved, the lack of specialized journalists, and restrictive laws which, until only recently, limited filming to rural areas.

Topic modeling enables exploration and compact representation of a corpus. The CaringBridge (CB) dataset is a massive collection of journals written by patients and caregivers during a health crisis. Topic modeling on the CB dataset, however, is challenging due to the asynchronous nature of multiple authors writing about their health journeys. To overcome this challenge we introduce the Dynamic Author-Persona topic model (DAP), a probabilistic graphical model designed for temporal corpora with multiple authors. The novelty of the DAP model lies in its representation of authors by a persona --- where personas capture the propensity to write about certain topics over time. Further, we present a regularized variational inference algorithm, which we use to encourage the DAP model's personas to be distinct. Our results show significant improvements over competing topic models --- particularly after regularization, and highlight the DAP model's unique ability to capture common journeys shared by different authors.

El presente artículo muestra resultados de un proyecto de investigación que los autores se encuentran desarrollando acerca de la crítica literaria chilena desarrollada en los medios de prensa. En este marco, proponemos la revisión del desarrollo inicial de la crítica en los albores del siglo XIX, así como la importancia de la prensa en la formación del sistema cultural chileno. Se muestra como el ejercicio crítico se inicia con el primer periódico chileno, La Aurora de Chile, y es cristalizado en el trabajo crítico de Andrés Bello.

Los medios digitales han transformado la profesión periodística en formas decisivas; tanto así, que el periodismo se ha vuelto difuso y sus fronteras y las normas se han desdibujado. En este trabajo teórico y narrativo nos fijamos en algunas de las implicaciones del proceso para la gestión de medios de comunicación, mientras que las organizaciones tratan de hacerle frente a un nuevo tipo de ecología de los medios. La transformación digital ha traído a la luz las preocupaciones acerca de la responsabilidad y las normas, lo que ha provocado un sano debate sobre el futuro de "los medios de comunicación heredados", con interesantes antecedentes en el pasado.
