Adding a new station and a road link to a road-rail network in the presence of modal competition

Perea Rojas Marcos, Federico; Mesa López-Colmenar, Juan Antonio; Laporte, Gilbert (Elsevier, 2014-10)

In this paper we study the problem of locating a new station on an existing rail corridor and a new junction on an existing road network, and connecting them with a new road segment under a budget constraint. We consider ...
Anterior cingulate cortex cells identify process-specific errors of attentional control prior to transient prefrontal-cingulate inhibition

Shen, C.; Ardid-Ramírez, Joan Salvador; Kaping, D.; Westendorff, S.; Everling, S.; Womelsdorf, T. (Oxford University Press, 2015-08)

[EN] Errors indicate the need to adjust attention for improved future performance. Detecting errors is thus a fundamental step to adjust and control attention. These functions have been associated with the dorsal anterior ...
Aspects of RG-spaces

Abohalfya, F.; Raphael, R. (Universitat Politècnica de València, 2012-04-01)

[EN] A Tychonoff space X which satisfies the property that G(X) = C(Xδ) is called an RG-space, where G(X) is the minimal regular ring extension of C(X) inside F(X), the ring of all functions from X to R, and Xδ is the ...
Attentional selection can be predicted by reinforcement learning of task-relevant stimulus features weighted by value-independent stickiness

Balcarras, M.; Ardid-Ramírez, Joan Salvador; Kaping, D.; Everling, S.; Womelsdorf, T. (MIT Press, 2016-02-01)

[EN] Attention includes processes that evaluate stimuli relevance, select the most relevant stimulus against less relevant stimuli, and bias choice behavior toward the selected information. It is not clear how these processes ...
