GeoWorlds: Integrating GIS and digital libraries for situation understanding and management
No full textHelping organizations to marshal, analyze, discuss, and act on all of the available information about a situation playing out over space and time is a critical problem. GeoWorlds (http://www.isi.edu/geoworlds) is a component-based information management system that addresses this issue. It brings together information analysis, retrieval and collaboration tools and integrates digital library, geographic information systems (GIS), and remote sensor data management technologies. It provides three key services: 1) rapidly assembling a custom repository of geographic information about a region, 2) bi-directionally linking it to collections of document-based information from the World-Wide Web, and 3) monitoring real-time sensor data for information that might change conclusions or decisions formed on the basis of this rich information set. GeoWorlds framework enables synchronous and asynchronous collaboration over finding, filtering, organizing and visualizing the needed information
The blind spots of secularization
No full textAccording to several international surveys Spain is among the western countries with the most negative views of Jews. While quantitative data on the topic accumulates, there is a significant lack of interpretative approaches that might explain the particular Spanish case. This paper presents the background, methodology and major results of a discussion group-based study on antisemitism, which was conducted in Spain in the autumn of 2009. The study identifies and locates in different socio-economic and ideological milieus the range of stereotypical discourses on Jews, Judaism and the Arab–Israeli conflict in Spain. Analysis of the group meetings shows that, despite growing secularization in Spanish society, the central explanatory variable for persisting and resurging antisemitism in this country is still religion in a broad cultural sense.N

No full textDetecting pathogens and mounting immune responses upon infection is crucial for animal health. However, these responses come at a high metabolic price (McKean and Lazzaro, 2011, Kominsky et al., 2010), and avoiding pathogens before infection may be advantageous. The bacterial endotoxins lipopolysaccharides (LPS) are important immune system infection cues (Abbas et al., 2014), but it remains unknown whether animals possess sensory mechanisms to detect them prior to infection. Here we show that Drosophila melanogaster display strong aversive responses to LPS and that gustatory neurons expressing Gr66a bitter receptors mediate avoidance of LPS in feeding and egg laying assays. We found the expression of the chemosensory cation channel dTRPA1 in these cells to be necessary and sufficient for LPS avoidance. Furthermore, LPS stimulates Drosophila neurons in a TRPA1-dependent manner and activates exogenous dTRPA1 channels in human cells. Our findings demonstrate that flies detect bacterial endotoxins via a gustatory pathway through TRPA1 activation as conserved molecular mechanism.sponsorship: Vlaams Instituut voor Biotechnologie Alessia Soldano Luis Franco Guangda Liu Natalia Mora Emre Yaksi Bassem A Hassanr Fonds Wetenschappelijk Onderzoek G.0702.12 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0077.15 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0680.10 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0681.10 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0503.12 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0654.15 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0761.10N Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0596.12 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar Fonds Wetenschappelijk Onderzoek G.0565.07 Alessia Soldano Yeranddy A Alpizar Brett Boonen Alejandro Lopez-Requena Natalia Mora Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar KU Leuven GOA/14/011 Alessia Soldano Yeranddy A Alpizar Brett Boonen Luis Franco Alejandro Lopez-Requena Guangda Liu Natalia Mora Emre Yaksi Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar European Commission IUAP P7/13 Alessia Soldano Yeranddy A Alpizar Brett Boonen Luis Franco Alejandro Lopez-Requena Guangda Liu Natalia Mora Emre Yaksi Thomas Voets Rudi Vennekensr KU Leuven OT/12/091 Alessia Soldano Yeranddy A Alpizar Brett Boonen Luis Franco Alejandro Lopez-Requena Guangda Liu Natalia Mora Emre Yaksi Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talaverar KU Leuven PF-TRPLe Alessia Soldano Yeranddy A Alpizar Brett Boonen Luis Franco Alejandro Lopez-Requena Guangda Liu Natalia Mora Emre Yaksi Thomas Voets Rudi Vennekens Bassem A Hassan Karel Talavera (Vlaams Instituut voor Biotechnologie, Fonds Wetenschappelijk Onderzoek|G.0702.12, Fonds Wetenschappelijk Onderzoek|G.0077.15, Fonds Wetenschappelijk Onderzoek|G.0680.10, Fonds Wetenschappelijk Onderzoek|G.0681.10, Fonds Wetenschappelijk Onderzoek|G.0503.12, Fonds Wetenschappelijk Onderzoek|G.0654.15, Fonds Wetenschappelijk Onderzoek|G.0761.10N, Fonds Wetenschappelijk Onderzoek|G.0596.12, KU Leuven|GOA/14/011, KU Leuven|OT/12/091, European Commission|IUAP P7/13, KU Leuven PF-TRPLe)status: Publishe
Accelerating Machine Learning Queries with Linear Algebra Query Processing
No full textThe rapid growth of large-scale machine learning (ML) models has led numerous commercial companies to utilize ML models for generating predictive results to help business decision-making. As two primary components in traditional predictive pipelines, data processing, and model predictions often operate in separate execution environments, leading to redundant engineering and computations. Additionally, the diverging mathematical foundations of data processing and machine learning hinder cross-optimizations by combining these two components, thereby overlooking potential opportunities to expedite predictive pipelines. In this paper, we propose an operator fusing method based on GPU-accelerated linear algebraic evaluation of relational queries. Our method leverages linear algebra computation properties to merge operators in machine learning predictions and data processing, significantly accelerating predictive pipelines by up to 317x. We perform a complexity analysis to deliver quantitative insights into the advantages of operator fusion, considering various data and model dimensions. Furthermore, we extensively evaluate matrix multiplication query processing utilizing the widely-used Star Schema Benchmark. Through comprehensive evaluations, we demonstrate the effectiveness and potential of our approach in improving the efficiency of data processing and machine learning workloads on modern hardware.Web Information System
Alma, impulso y movimiento según Alejandro de Afrodisia
No full textthis paper discusses Alexander of Aphrodisias’ conception of the soul, paying special attention to a specific aspect distinguishing the Alexandrian view from the Aristotelian one: the impulsive capacity or faculty. Firstly, it considers Alexander’s reformulation of Aristotle’s approach to the soul (as a form of the body), a reformulation that is performed in connection with his original reconstruction of hilemorphism. At this point the author makes a special emphasis upon the manner Alexander develops a ‘terraced model’ of hilemorphic composition. Secondly, the treatment of impulsive faculty, with a special focus on the theoretical performance that Alexander derives from taking the notion of impulse, is developed. Finally, Alexander’s reformulation of the Aristotelian psychology of action is also brie y considered in order to account for the sequence of the process of the production of voluntary movement and of action. This is an explicative model that leaves aside the Aristotelian resource to the structure of the practical syllogism, and incorporates the elements predominantly characteristic of the Stoic conception. This, though, does not entail the abandonment of the basic thesis of Aristotle’s stance regarding motivation, as an opposition to socratic intellectualism: the thesis of the primacy of desire, in all its possible ways, as a factor accounting for the origin of voluntary movement and action.Este artículo se ocupa de la concepción del alma elaborada por Alejandro de Afrodisia, con especial atención a un aspecto específico que la distingue de la concepción aristotélica: la introducción de una facultad o capacidad impulsiva. En primer lugar, se considera la reformulación de la concepción jaristotélica del alma como forma del cuerpo que Alejandro lleva a cabo, en conexión con su original reconstrucción del hilemorfismo. Aquí se pone especial énfasis en el modo en el cual Alejandro construye lo que puede llamarse un “modelo escalonado” de composición hilemórfica. En segundo lugar, se considera el tratamiento de la facultad impulsiva, atendiendo especialmente al rendimiento teórico que extrae Alejandro de la adopción de la noción de impulso. Por último, se considera brevemente el modelo reformulado de psicología de la acción que elabora Alejandro, para dar cuenta de la secuencia del proceso de producción del movimiento voluntario y la acción. Se trata de un modelo explicativo que deja de lado el recurso aristotélico a la estructura del silogismo práctico e incorpora, en cambio, los elementos más característicos de la concepción estoica. Ello no implica, sin embargo, el abandono de la tesis básica de la concepción aristotélica de la motivación, por oposición al intelectualismo socrático, a saber: la tesis de la primacía del deseo, en todas sus posibles formas, como factor que da cuenta del origen del movimiento voluntario y la acción

Cómo vamos a vivir juntos?
No full textThis book by Alejandro Aravena explores the critical question of coexistence in modern societies, particularly in the context of urban planning, social participation, and the collective challenges we face in the 21st century. The book originates from a keynote speech given by the author at the Chilean Constitutional Convention in 2021, where he reflected on the future of society and urban development over the next century.
Drawing from his extensive experience in architecture and participatory design, Aravena presents key lessons learned through real-world projects and community engagement. These principles emphasise the importance of inclusive urban planning, equitable resource distribution, and the balance between regulation and self-regulation. The book argues that solving complex social issues requires more than just good intentions. It demands a deep understanding of diverse perspectives and a willingness to embrace dialogue and collaboration.
A central theme is the idea that neither the market nor the state alone can provide sustainable solutions for urban and social challenges. Instead, the book advocates for a "third way" that trusts in people's agency, acknowledging their role as active contributors to the built environment rather than passive recipients of top-down policies. The text highlights the need to shift from mere tolerance to genuine admiration for cultural diversity, particularly in the context of the Chilean-Mapuche relationship. To this aim, the author explores the potential of indigenous knowledge, historical negotiation practices, and the power of storytelling in shaping a shared future.
By blending architectural insight with sociopolitical analysis, this book serves as a manifesto for collective responsibility, urging readers to rethink how cities, policies, and communities can be designed to foster sustainable and harmonious living conditions
Review book Alejandro Herrero
No full textThe work entitled “From the United Provinces to the Argentine Nation. An approach”, by the author Alejandro Herrero, consists of six chapters and a documentary appendix that has six documents. In the first instance, the writing itself unfolds in a reinterpretation of the origins of nationalities. He maintains that in the Argentine Republic, nationality does not come from the national State directly, but rather they have different historical moments
