A Broadband Bow-Tie Cavity-Backed Slot for Traveling-Wave Arrays in the Millimeter-Wave Band

The use of bow-tie geometries to enhance the characteristics of a radiating element previously proposed by the authors is presented. The previous element consisted of a broadband cavity-backed slot in transmission configuration. The bow-tie shape of the cavity improves the bandwidth of the element and the bow-tie slot keeps constant the amount of power radiated. The structure is designed for the millimeterwave band. The enhancement of the element performance is shown through simulation results. A fractional bandwidth of more than 100% is achieved in the 70 GHz band, and the radiated power remains almost constant throughout 30 GHz of the bandwidth. These results show a great improvement over the original radiating element. The radiating structure has the ideal characteristics for building series-fed reconfigurable arrays for wide-band applications in the millimeter-wave band.Universidad de Málaga.

Consciousness, Meaning and the Future Phenomenology

Phenomenological states are generally considered sources of intrinsic motivation for autonomous biological agents. In this paper we will address the issue of exploiting these states for robust goal-directed systems. We will provide an analysis of consciousness in terms of a precise definition of how an agent “understands” the informational flows entering the agent. This model of consciousness and understanding is based in the analysis and evaluation of phenomenological states along potential trajectories in the phase space of the agents. This implies that a possible strategy to follow in order to build autonomous but useful systems is to embed them with the particular, ad-hoc phenomenology that captures the requirements that define the system usefulness from a requirements-strict engineering viewpoint

La educación del estudiante con discapacidad auditiva: experiencia en la escuela inclusiva

La ponencia presentada a la consideración del Comité del XIX Congreso Internacional INFAD, responde al eje temático: discapacidad, que busca aportar al proceso educativo, el principal objetivo es contribuir con buenas prácticas al sistema educativo y conocer la situación de aprendizaje de los estudiantes con discapacidad auditiva. En una escuela abierta a la diversidad que busca educar en competencias para la vida, en este caso específico dirigido a estudiante con discapacidad auditiva, la educación de la persona sorda se ha constituido durante mucho tiempo en el principal foco de interés en los docentes, hoy tenemos propuestas metodológicas innovadoras para la enseñanza de habilidades lectoras y escritoras del estudiante con discapacidad auditiva lo que se pretende es compartir nuevas formas de ver y entender el proceso de aprendizaje en los estudiantes. De igual forma compartir herramientas conceptuales y prácticas de la adquisición de la lectura sobre la base del descubrimiento y la utilización en contextos comunicativos reales en una escuela común. Al final de la propuesta de ponencia queremos reflexionar sobre como ajustar todos las formas de mediación pensadas para oyentes a la condición de la discapacidad sensorial basada en los principios rectores de educación para todos, respeto, justicia, y oportunidades para aprender.The conference submit to the Scientific Commitee of the INFAD XIX International Congress; the presentation respond to a thematic disabled, want to contribute into the educational process, the main objective to contribute the best practices to the educational system and known the learning condition to the disabled auditory student. Into an school open to diversification wants to educate into competences for the life, in the specific case oriented to disables auditory students , the education of the deaf person constitute during a very long time into the main focus of interest to docents, today we have innovatives methodological propossals to teach writing and reading habilities of the disabled auditory student, we try to share new form to understandig the learning process of the students. At the same manner show the conceptual tools and practices of the reading adquisitions based at the descovery and use into real communicative contexts, in a common school. At the end of the proppossal we hope to thought about adjust all the thinked manners of mediation to listener persons to the condition of the perceptive disabled based at the rector principles of the education for all, respect, justice, and opportunities to learn

Psychological capital and entrepreneurship: A systematic literature review of a growing research agenda

Purpose: Psychological resources are determinant for the entrepreneur's individual performance.Psychological capital has been seen as one of the pillars of entrepreneurship and this is one of thereasons that the study of the relationship between these two constructs is emerging. The primary focusof this article is to analyze the development in the literature on entrepreneurship and psychologicalcapital, as well as providing a set of avenues for future research. Design/methodology: This systematic review used the PRISMA Protocol and the VOS viewersoftware for cluster analysis. The articles gathered for this article cover the annual period from 2013 to2022 and allow the identification and analysis of the main themes on psychological capital andentrepreneurship.Findings: The systematic analysis brought to light integrative relationships between the concepts ofpositive psychological capital and entrepreneurship, which allowed the construction of an overview ofthis spectrum of study. This resulted in four large groups of analysis that point the direction of theliterature. The main contributions resulted in the presentation of principles and recent scientific ideaswhich consider psychological capital as a valuable resource for entrepreneurship.Originality/value: This systematic review of the literature contributes to a more robust and groundedunderstanding of this relationship. In addition, this research provides an incisive understanding ofpsychological capital and the entrepreneurship research agenda with the aim of being a starting point fordeepening knowledge about the synergies of studies on both themes. Finally, a set of future lines ofstudy is also proposedPeer Reviewe

Moduli Spaces of Semistable Sheaves on Singular Genus One Curves

We find some equivalences of the derived category of coherent sheaves on a Gorenstein genus one curve that preserve the (semi)-stability of pure dimensional sheaves. Using them we establish new identifications between certain Simpson moduli spaces of semistable sheaves on the curve. For rank zero, the moduli spaces are symmetric powers of the curve whilst for a fixed positive rank there are only a finite number of non-isomorphic spaces. We prove similar results for the relative semistable moduli spaces on an arbitrary genus one fibration with no conditions either on the base or on the total space. For a cycle $E_N$ of projective lines, we show that the unique degree 0 stable sheaves are the line bundles having degree 0 on every irreducible component and the sheaves $\mathcal{O}(-1)$ supported on one irreducible component. We also prove that the connected component of the moduli space that contains vector bundles of rank $r$ is isomorphic to the $r$-th symmetric product of the rational curve with one node.Comment: 26 pages, 4 figures. Added the structure of the biggest component of the moduli space of sheaves of degree 0 on a cycle of projective lines.

Use of Antidepressants in Children and Adolescents

Depression is a serious disorder that can cause significant problems in mood, thinking, and behavior at home, in school, and with peers. It is estimated that major depressive disorder (MDD) affects about 5% of adolescents. Research has shown that, as in adults, depression in children and adolescents is treatable. Certain antidepressant medications, called selective serotonin reuptake inhibitors (SSRIs), can be beneficial to children and adolescents with MDD. Certain types of psychological therapies also have been shown to be effective. However, our knowledge of antidepressant treatments in youth, though growing substantially, is limited compared to what we know about treating depression in adults. The U.S. Food and Drug Administration (FDA) issued a public warning in October 2004 about an increased risk of suicidal thoughts or behavior (suicidality) in children and adolescents treated with SSRI antidepressant medications. However, SSRI medications are considered to have an improvement over older antidepressant medications and they have been shown to be safe and effective for adults. In this chapter we provide an updated and well-documented review of the current scientific evidence on this topic
