Strong chain transitivity in hyperspaces of uniform spaces
Get PDFWe apply topological definitions of strong chain transitivity and characterizetopological strong chain transitivity for the induced maps on hyperspaces ofuniform spaces. We prove that, if the induced maps on such hyperspaces exhibittopological strong chain transitivity then the base map satisfies the propertyof topological strong chain transitivity
Dynamical behavior of a general non-autonomous dynamical system
Get PDFIn this work, we investigate dynamical notions such as minimality, almost periodicity, equicontinuity, transitivity, proximality and periodicity for a general non-autonomous dynamical system. We provide necessary and sufficient conditions for a non-autonomous system to be minimal. We prove that for an equicontinuous system (X,F), if x is almost periodic then OH(x) is uniformly almost periodic. We also establish preservance of almost periodicity under uniform convergence. We also establish some results capturing the qualitative behavior of a general non-autonomous dynamical system
C1(X) on the edge of C2(X)
Get PDFGiven a continuum X and a positive integer n, let Cn(X) be the hyperspace consisting of all nonempty closed subsets of X having at most n components. For a subcontinuum A of X having empty interior, consider the following properties: A is a subcontinuum of colocal connectedness, X\A is continuumwise connected, A is a nonblock subcontinuum, A is a shore subcontinuum, A is not a strong centre. In this paper, we prove that C1(X) has all of these properties in Cn(X) if n ≥ 3, and we study when C1(X) has one of these properties in C2(X)
Pre-symmetric c-distances and characterization of complete cone metric spaces
Get PDFThe main goal of this research is to express the definition of pre-symmetric c-distances in cone metric spaces inspired by pre-symmetric w-distances defined by Romaguera and Tirado [Mathematics. 12 (2024), 2:305] and give the properties of this type of c-distances along with some examples. Then we introduce Suzuki's theorem regarding a pre-symmetric c-distance and obtainrelationship between several important contractions with respect to cone metric spaces. Finally, we will state a characterization of the completeness of cone metrics using fixed point theorems, which is different from previous descriptions of complete cone metric spaces
β-Normality in locales
Get PDFIn this paper, we establish the theory of β-normal locales which are the point- free counterparts of β-normal spaces which were introduced by Arkhangel’skii and Ludwig. We give characterizations of β-normal locales using some types of open sublocales. Certain circumstances are exhibited in which normality coincides with β-normality. For instance, we use the localic Kateˇtov-Tong insertion theorem to prove that every β-normal locale which is also a coframe is normal. This result argues that there does not exist a finite β-normal locale which is not normal. Included here is also an answer to Murtinova ́’s question about the existence of a regular β-normal space which is not Tychonoff. The study of β-normal locales leads to some variants of β-normal locales, namely α-normal locales and almost weakly β-normal locales. This paper also examines preservation and reflection of β-normal locales by localic maps
Net art died but is doing well: anotaciones
Get PDFThe production of art conceived for the Internet experienced a period of decline in the 2010s. However, with the need for social isolation due to the COVID-19 pandemic starting in 2020, artists turned their attention to the Internet as a medium of creation, transcending the diffusion of other types of art works. Production is strengthened, with a substantial number of creations conceived during the critical period of the Pandemic. But, as life goes back to normal, is Internet art production destined for a new downfall? In light of this, artists Fabio FON and Soraya Braz launched a call for artists entitled Net art died but is doing well, with the purpose of understanding the current status of that production. An online exhibition is held in the context of the sixth edition of The Wrong Biennale, one of the largest digital art events in the world, which started in November 2023.La producción de arte concebida para Internet vivió un período de declive durante la década de 2010. Sin embargo, con la necesidad de aislamiento social debido a la pandemia de COVID-19 a partir de 2020, la atención de los artistas se centró nuevamente en Internet como un medio de creación, yendo más allá de la simple difusión de obras creadas en otros lenguajes. La producción resurge, con numerosas creaciones durante el período crítico de la pandemia. Pero, a medida que la vida vuelve a la normalidad, ¿estarán las obras para Internet destinadas a un nuevo declive? Para reflexionar sobre esto, los artistas Fabio FON y Soraya Braz lanzaron una convocatoria abierta para artistas titulada Net art died but is doing well con el propósito de entender el estado actual de esta producción. Una exposición en línea se lleva a cabo en el contexto de la sexta edición de The Wrong Biennale, uno de los mayores eventos de arte digital del mundo, a partir de noviembre de 2023
A Systematic Literature Review Protocol to understand the Healthcare Service Innovation Ecosystem
Get PDFThe research's primary goal is to address the innovation ecosystem in healthcare services to understand how interaction among stakeholders occurs and how that interaction influences or does not influence the results obtained from the innovation process. We aim to build a theoretical model applicable to the healthcare sector context regarding the questions we aim to answer through systematic review: Does the relationship between stakeholders of the Health Services Innovation Ecosystem affect innovation outcomes? The target population includes the actors within the ecosystem (partners, stakeholders, and other participants); the phenomenon of interest is how these actors interact, with the context being the innovation process, specifically focusing on the outcomes of their interactions. This article defines the framework proposal for systematic review. A methodological approach was developed considering the parameters of the PRISMA 2020 Statement since the definition of the review objective was to collect and analyze data. As a result, the research question has been validated, and studies included in the review have been identified. The results will be analyzed and generated in the following research phase
Las perspectivas de cuadro horizontal y algunas imágenes cenitales de las escaleras en el cine
Get PDFThe conical perspective using the horizontal picture plane, known in painting since the Renaissance, was employed for the ‘upward’—nadir— view of the decoration of ceilings and domes in numerous famous works of art. However, the opposite ‘downward’—zenithal—view was much less common, being limited to exceptional theoretical proposals in manuals. This article describes how the situation was reversed following the birth of film, when the zenithal view became comparatively predominant. As proof, we cite examples of its application to staircases in different films from the first half of the 20th century. We also make special mention of its use by Alfred Hitchcock, referencing a series of famous zenithal shots that have influenced the art of film.La perspectiva cónica utilizando el plano del cuadro horizontal, conocida en la pintura desde el Renacimiento, fue utilizada para la decoración de techos y cúpulas 'mirando hacia arriba', -nadir- en numerosas y conocidas obras de arte. Sin embargo la visión contraria 'mirando hacia abajo -cenital- lo fue mucho menos, hasta ser tan solo una propuesta teórica y excepcional limitada a los manuales. Exponemos aquí que la adopción utilizada en el inicio del cine fue completamente la contraria, siendo la visión cenital comparativamente preponderante. Para ello tomamos una serie de ejemplos de su aplicación a las escaleras en diversas películas de la primera mitad del siglo XX. Hacemos también una especial mención de su empleo por Alfred Hitchcock, con una serie de tomas cenitales muy conocidas e influyentes en el arte cinematográfico
Tapas Duras: sobre como un vermut puede cambiarlo todo y lo que haces con tu tiempo libre
Get PDFIn a context dominated by the cult of productivity and performance, Tapas Duras emerges as an editorial design collective that advocates for the opposite: enjoyment, slow design, conversation, and hands-on making. What began as an adventure among photobooks and vermouth gradually evolved into a committed and intense editorial practice, where ideas arise from close relationships with authors, material exploration, and a tactile, intuitive approach.En un contexto dominado por el culto a la productividad y el rendimiento, Tapas Duras surge como un colectivo de diseño editorial que apuesta por lo contrario: el disfrute, el diseño pausado, la conversación y el hacer con las manos. La aventura que comenzó entre fotolibros y vermuts, derivó en una práctica editorial comprometida e intensa donde las ideas surgen de los vínculos con los autores, la exploración material y el enfoque táctil e intuitivo
University 4.0: Professors' Perceptions’ on the Future of Higher Education. Evolutionary Progress or Revolutionary Change?
Get PDFThe convergence of several emerging technologies such as artificial intelligence (AI), the Internet of Things (IoT), blockchain, 3D printing, big data, and augmented reality into the fourth industrial revolution has profoundly changed all facets of life, including higher education. The speed and nature of change in the aim and structure of the University of the Future may take two paths: evolutionary, termed the University 4.0 model, or revolutionary, called the University 4.1 model. A semi-structured survey was designed to explore the perception of university professors about the University of the Future. A total of 142 professors from 23 countries responded to the study. The results gave valuable insights into the vision of the world's academic community for University 4.0/4.1
