Diagrammatic Expansion for Positive Spectral Functions in the Steady-State Limit
2019
Recently, a method was presented for constructing self-energies within many-body perturbation theory that are guaranteed to produce a positive spectral function for equilibrium systems, by representing the self-energy as a product of half-diagrams on the forward and backward branches of the Keldysh contour. We derive an alternative half-diagram representation that is based on products of retarded diagrams. Our approach extends the method to systems out of equilibrium. When a steady-state limit exists, we show that our approach yields a positive definite spectral function in the frequency domain.
Making Industrial Robots Smarter with Adaptive Reasoning and Autonomous Thinking for Real-Time Tasks in Dynamic Environments: A Case Study
2018
In order to extend the abilities of current robots in industrial applications towards more autonomous and flexible manufacturing, this work presents an integrated system comprising real-time sensing, path-planning and control of industrial robots to provide them with adaptive reasoning, autonomous thinking and environment interaction under dynamic and challenging conditions. The developed system consists of an intelligent motion planner for a 6 degrees-of-freedom robotic manipulator, which performs pick-and-place tasks according to an optimized path computed in real-time while avoiding a moving obstacle in the workspace. This moving obstacle is tracked by a sensing strategy based on ma-chin…
Smart sensing and adaptive reasoning for enabling industrial robots with interactive human-robot capabilities in dynamic environments — a case study
2019
Traditional industry is seeing an increasing demand for more autonomous and flexible manufacturing in unstructured settings, a shift away from the fixed, isolated workspaces where robots perform predefined actions repetitively. This work presents a case study in which a robotic manipulator, namely a KUKA KR90 R3100, is provided with smart sensing capabilities such as vision and adaptive reasoning for real-time collision avoidance and online path planning in dynamically-changing environments. A machine vision module based on low-cost cameras and color detection in the hue, saturation, value (HSV) space is developed to make the robot aware of its changing environment. Therefore, this vision a…
Practicing logical reasoning through Drosophila segmentation gene mutants.
2021
Laboratory practical sessions are critical to scientific training in biology but usually fail to promote logical and hypothesis-driven reasoning and rely heavily on the teacher's instructions. This paper describes a 2-day laboratory practicum in which students prepare and analyze larval cuticle preparations of Drosophila segmentation gene mutant strains. Embryonic segmentation involves three major classes of genes according to their loss-of-function phenotypes: the establishment of broad regions by gap genes, the specification of the segments by the pair-rule genes, and the compartments within segments by the segment polarity genes. Students are asked to sort undefined segmentation mutants …
The Logical Intelligence Enhancement Program (LIEP) for the improvement of cognitive abilities. Premilinary findings
2021
The Logical Intelligence Enhancement Program (LIEP) is a program specifically addressed to students aging from 6 to 12. It consists of a series of exercises of different types (verbal inferences, understanding of graphs and tables, series of digits, etc.) and increasing difficulty, properly devised to activate and train the abilities of logical reasoning. Hopefully, such an enhancement should result in an improvement of academic achievements, especially in low proficiency learner students. Here we report on a study carried out on a large cohort of fifth-grade students. The results demonstrate the effectiveness of LIEP in improving students’ cognitive abilities and abstract reasoning.
Metaphors in the mirror: The influence of teaching metaphors in a medical education programme
2016
Medical students often face problems in using and understanding metaphors when communicating with a patient or reading a scientific paper. These figures of speech constitute an interpretative problem and students need key strategies to facilitate metaphor comprehension and disambiguation of meaning. This article examines how medical students' strategies of metaphor comprehension could be improved by specific teaching on metaphors using a Cognitive Linguistics approach. Medical students' ability to comprehend mirror neuron metaphors was assessed comparing the performance of students who did not receive any instruction about metaphoric extension strategies after a lesson on mirror neurons wit…
Self-Organized Linguistic Systems: From traditional AI to bottom-up generative processes
2018
Este trabajo busca explorar el potencial de los procesos generativos bottom-up en el contexto de la producción conlang, con el objetivo de describir las bases de un nuevo campo de investigación: los Sistemas Lingüísticos Autoorganizados o SOLS, específicamente bajo la perspectiva doble de sistemas autoorganizados y lenguajes construidos. El enfoque SOLS proporciona un marco para la creación de lenguajes artificiales autogenerados y puede servir como punto de partida para el desarrollo de lenguajes dependientes del contexto o específicos del dominio. Reconoce que el desarrollo de conlangs puede ocurrir en sociedades artificiales de agentes simples, como resultado de interacciones sociales en…
Influència del sexe i l'edat en el raonament moral prosocial dels estudiants de secundària
2008
Aquest treball presenta una aproximació a l'estudi del raonament moral prosocial i de les variables que infl ueixen en el seu desenvolupament. L'objectiu principal és determinar en quina mesura la variable sexe i la variable edat infl ueixen en el raonament moral prosocial dels adolescents. L'estudi es realitza amb una mostra d'estudiants de secundària (n=114), homes i dones. Els resultats indiquen que les dues variables analitzades (sexe i edat) tenen un efecte signifi catiu sobre el raonament moral prosocial. Les dones, davant una situació d'ajudar o no l'altre, justifi quen la decisió en raons més abstractes i internalitzades, enfront dels homes, que se centren en l'aprovació i acceptaci…
Advancing beyond the system: telemedicine nurses' clinical reasoning using a computerised decision support system for patients with COPD - an ethnogr…
2017
Abstract Background Telemedicine is changing traditional nursing care, and entails nurses performing advanced and complex care within a new clinical environment, and monitoring patients at a distance. Telemedicine practice requires complex disease management, advocating that the nurses’ reasoning and decision-making processes are supported. Computerised decision support systems are being used increasingly to assist reasoning and decision-making in different situations. However, little research has focused on the clinical reasoning of nurses using a computerised decision support system in a telemedicine setting. Therefore, the objective of the study is to explore the process of telemedicine …
Developmental and content effects in reasoning with causal conditionals.
2002
Abstract Two predictions derived from Markovits and Barrouillet's (2001) developmental model of conditional reasoning were tested in a study in which 72 twelve-year-olds, 80 fifteen-year-olds, and 104 adults received a paper-and-pencil test of conditional reasoning with causal premises (“if cause P then effect Q”). First, we predicted that conditional premises would induce more correct uncertainty responses to the Affirmation of the consequent and Denial of the antecedent forms when the antecedent term is weakly associated to the consequent than when the two are strongly associated and that this effect would decrease with age. Second, uncertainty responding to the Denial of the antecedent f…
