While temporal variation is accomplished by delivering water at fixed or variable times, spatial variation is usually accomplished by varying the number of dispensers and distance among them. Such criteria do not consider the possible ecological relevance of the location of water dispensers. Nevertheless, it is plausible to suppose that the intersection of the programed contingencies (e.g., time-based schedules), the ecological differentiated space (e.g., open vs. closed zones), and the relative location of relevant objects and events (e.g., location of the water source—peripherical vs. center zone) could set up an integrated system with the behavioral patterns of the organism. In the present study, we evaluated the eco-functional relevance of two locations of the dispensers upon behavioral dynamics in Wistar rats using fixed and variab...

Materlales y m6todos: 53 pacientes con enfermedad renal cronica que acuden a un centro de hemodialisis fueron aleatorizados a recibir sesiones de Tai Chi tres veces por semana o a seguir con el tratamiento convencional.

It has been designed to manage non Geo-referenced information related to cultural heritage sites and artifacts. CHISel information is organized as a set of layers referencing to points on the artifact surface. Managing information means editing, rendering, querying, composing and analyzing. If you are currently using Georeferenced data it would probably be better to use a GIS. This document describes the main functionality of CHISel version 2.0. To cite this document, please use: J.C.

Some methods allow the users to combine different types of data in order to extract relevant information. In this context, the present paper shows the application of a model via a platform in order to group together information generated by Twitter users, thus facilitating the detection of trends and data related to particular symptoms. In order to implement the model, an analyzing tool that uses the Levenshtein distance was developed, to determine exactly what is required to convert a text into the following texts: ’gripa’-”flu”, ”dolor de cabeza”-”headache”, ’dolor de estomago’- ”stomachache”, ’fiebre’-”fever” and ’tos’- ”cough” in the area of Bogota. Among the ´ information collected, identifiable patterns emerged for each one of the texts.

The intermediate data transmitted can be used as a complete representation, allowing the client to perform any computation on the volume and to generate any isosurface. The experiments performed show that a good approximation can be achieved for medical data sets with less than ten per cent of the data transmitted. The hierarchical index used is a compressed BONO index (cell octree), that is also used to speed up the isosurface generation.

Subjects were 8 experimentally-naive, male Wistar rats divided in two groups of 4 rats. For both groups, two independent schedules of water delivery were simultaneously available in two different locations of the experimental chamber. For Group 1, water was delivered with a constant periodicity. For Group 2 water was delivered randomly in time but keeping constant the average length of time between deliveries. Water deliveries were independent of rat’s behavior. In successive phases of the study, the frequency of water delivered in one location increased while the frequency of water delivered in the second location decreased, keeping constant the total number of water deliveries. Rats under the constant periodicity spent more time in the location where water wa...

The framework relies on standard technologies and does not have special hardware requirements since just a smartphone, a remote 3D application and a wireless connection are required to set up the system, making it ideal for live environments where attenders can use their own smartphone to interact with remote 3D digital content. The framework provides a set of single-handed interaction techniques for smartphones and also provides with connection capabilities allowing to remotely interact with 3D content by combining the modern 3D sensing capabilities of these devices with touch-screen inputs. The prototype was set up and presented at the Digital Heritage 2015 Exposition, where attenders were able to remotely interact with 3D heritage models.

Nevertheless, under the standard approaches, the experimental analysis of behavior is based on the single response paradigm and the temporal distribution of discrete responses. Thus, the continuous analysis of spatial behavioral dynamics is a scarcely studied field. The technological advancements in computer vision have opened new methodological perspectives for the continuous sensing of spatial behavior. With the application of such advancements, recent studies suggest that there are multiple features embedded in the spatial dynamics of behavior, such as entropy, and that they are affected by programmed stimuli (e.g., schedules of reinforcement) at least as much as features related to discrete responses. Despite the progress, the characterization of behavioral systems is still segmented, and integrated data ana...

Nevertheless, it has two important limitations for its use in humans. The first one is the "ceiling effect" reported in linguistic participants. The second limitation is that the standard transposition task, being a simple choice task between two stimuli, does not include active behavioral patterns and their recording, as relevant factors in emergence of relational behavior. In the present work, a challenging multi-object task based on transposition, integrated with recording software, is presented. This paradigm requires behavioral active patterns to form stimuli compounds with a given relational criteria. The paradigm is composed of three arrangements: a) a bank of stimuli, b) sample relational compounds, and c) comparison relational compounds. The task consists of the participant constructing two comparison relational compounds by dragging figures of a bank of stimuli with the same relation shown by the sample relational compounds. These factors conform an integrated system that can be manipulated in an individual or integrative manner. The software records discrete responses (e.g., stimuli selections, placements) and continuous responses (e.g., tracking of cursor movements, figure dragging). The obtained data, data analysis and graphical representations proposed are compatible with frameworks that assume an active nature of the attentional and perceptual processes and an integrated and continuous system between the perceiver and the environment. The proposed paradigm deepens the systematic study of relational behavior in humans in the framework of the transposition paradigm and expands it to a continuous analysis of interaction between active patterns and the dynamics of relational behavior.

Most of the literature has tackled this problem assuming a discrete choice model dependent on the ports’ characteristics and agents’ attributes. However, in practice the port choice decision depends also on the choices made by other agents as well as decisions made by these agents in the past. There are only a few examples that incorporate the complexity generated by spatio-temporal interactions between agents. However, those modelling structures are rather cumbersome, precluding their use in practical cases. This article presents a new modelling framework to predict port choice decisions, based on the theory of Cellular Automaton (CA), which is simple in structure and can be quickly calibrated and applied. This framework is a probabilistic CA intended to imitate the decision processes made from multiple shippers that interact with each other. These shippers ...
