    This study explores the concept of creativity and artificial intelligence (AI) and their recent integration. While AI has traditionally been perceived as incapable of generating new ideas or creating art, the development of more sophisticated AI models and the proliferation of human-computer interaction tools have opened up new possibilities for AI in artistic creation. This study investigates the various applications of AI in a creative context, differentiating between the type of art, language, and algorithms used. It also considers the philosophical implications of AI and creativity, questioning whether consciousness can be researched in machines and AI's potential interests and decision-making capabilities. Overall, we aim to stimulate a reflection on AI's use and ethical implications in creative contexts

    Multidirectional ECG Coherent Optimal Timing of Defibrillation Shocks

    A method for of delivering a defibrillation shock to a heart at an optimal time to stop ventricular fibrillation which involves obtaining an electrocardiogram of a heart in at least two directions, determining a time-coherency of the electrocardiogram based upon each of the at least two directions, and computing a tracking function from the time-coherency. An optimal time to apply a defibrillation shock to the heart is determined by locating a local maximum on the tracking function. The method utilizes spacia characteristics of the ventricular fibrillation. The method can be incorporated into implantable cardioverter defibrillators utilizing existing hardware technology

    Ventricular Fibrillation in an Afebrile COVID-19 Patient Presenting With Transient Type-I Brugada Pattern.

    COVID-19 has been associated with an increased risk of both atrial and ventricular arrhythmias. Brugada syndrome (BrS), an inherited sodium channelopathy presenting with a characteristic ECG morphology, confers a baseline risk of ventricular arrhythmias such as ventricular fibrillation (VF), especially during febrile illnesses. However, mimics of BrS, termed Brugada phenocopies (BrP), have been noted in association with fever, electrolyte abnormalities, and toxidromes outside of viral illness. Such presentations manifest the same ECG pattern, the type-I Brugada pattern (type-I BP). Thus, the acute stage of an illness such as COVID-19, when accompanied by a first-time presentation of type-I BP, may not result in a certain diagnosis of BrS versus BrP. Thus, expert recommendations are to anticipate arrhythmia regardless of the presumed diagnosis. Here we demonstrate the importance of these guidelines and a novel report of VF in the setting of a transient type-I BP in afebrile COVID-19. We discuss the potential factors which may have triggered VF, the presentation of isolated coved ST elevation in V1, and the difficulty of BrS versus BrP diagnosis in acute illness. In summary, a SARS-CoV-2 positive 65-year-old male without significant cardiac history for BrS presented with type-I BP after two days of shortness of breath. Hypoxemia, hyperkalemia, hyperglycemia, elevated inflammatory markers, and acute kidney injury were present. After treatment, his ECG normalized; however, aborted VF occurred days later while afebrile and normokalemic. Follow-up ECG again revealed a type-I BP, which also became more apparent during an episode of bradycardia, a classic finding in BrS. This case suggests that there is room for larger studies to determine the prevalence and outcomes when type-I BP presents in acute COVID-19. When possible, genetic data should be obtained to confirm BrS, a notable limitation in our case. Regardless, it corroborates guideline-directed clinical management, with heightened vigilance for arrhythmia in such patients until full recovery

    This article aims to demonstrate the capacity of geoprocessing tools, including images from different sensory systems, to contribute to the characterization, both synchronous and diachronic, of regions that require land regularization. Through the application of geoprocessing tools aligned with aerial photogrammetric products in urban assessment, we seek to demonstrate the presence and progression of peripheral informal occupation in the city of Ribeirão Preto, in the interior of the state of São Paulo. This scenario is used as an emblematic example of the favelaization phenomenon observed in medium-sized cities in the interior of São Paulo.Este artículo tiene como objetivo demostrar la capacidad de las herramientas de geoprocesamiento, incluidas imágenes de diferentes sistemas de sensores, para contribuir a la caracterización, tanto sincrónica como diacrónica, de regiones que requieren una regularización territorial. Mediante la aplicación de herramientas de geoprocesamiento en conjunto con productos fotogramétricos aéreos en la evaluación urbana, buscamos evidenciar la presencia y progresión de la ocupación informal periférica en la ciudad de Ribeirão Preto, en el interior del estado de São Paulo. Este escenario se utiliza como un ejemplo representativo del fenómeno de favelización observado en ciudades medianas del interior de São Paulo.Neste artigo, tem-se como objetivo demonstrar a capacidade das ferramentas de geoprocessamento, incluindo imagens oriundas de diversos sistemas sensoriais, em contribuir para a caracterização, tanto sincrônica como diacrônica, de regiões que demandam regularização fundiária.
