To investigate the time course of attentional object selection processes in visual search tasks where targets are defined by a combination of features from the same dimension, we measured the N2pc component as an electrophysiological marker of attentional object selection during colour/colour conjunction search. In Experiment 1, participants searched for targets defined by a combination of two ...

The cooperative games with fuzzy coalitions in which some players act in a coalition only with a fraction of their total “power” (endeavor, investments, material, etc.) or in which they can distribute their “power” in more coalitions, are connected with some formal or interpretational problems. Some of these problems can be avoided if we interpret each fuzzy coalition as a fuzzy class of crisp ...

Understanding quantum channels and the strange behavior of their capacities is a key objective information theory. Here we study remarkably simple, low-dimensional, single-parameter family with exotic information-theoretic features. As simplest example from this family, focus on qutrit-to-qutrit channel that intuitively obtained by hybridizing together simple degradable completely useless qubit...

The error threshold of a one-parameter family quantum channels is defined as the largest noise level such that capacity channel remains positive. This in turn guarantees existence correction code for modeled by channel. Discretizing single-qubit errors leads to important Pauli channels; curiously, multipartite entangled states can increase these beyond so-called hashing bound, an effect termed ...

In this paper we prove exact forms of large deviations for local times and intersection local times of fractional Brownian motions and Riemann–Liouville processes. We also show that a fractional Brownian motion and the related Riemann–Liouville process behave like constant multiples of each other with regard to large deviations for their local and intersection local times. As a consequence of o...

A graph is planar if it can be embedded in the plane, or in the sphere, so that no two edges cross at an interior point. A planar graph together with a particular embedding is called a map. There is a rich theory of counting maps, started by Tutte in the 1960’s. However, in this paper we are interested in counting graphs as combinatorial objects, regardless of how many nonequivalent topological...

The paper is concerned with a dissipativity theory and robust performance analysis of discrete-time stochastic systems driven by a statistically uncertain random noise. The uncertainty is quantified by the conditional relative entropy of the actual probability law of the noise with respect to a nominal product measure corresponding to a white noise sequence. We discuss a balance equation, dissi...

Different forms of antagonism are classified in terms of response types and are related to the sufficient-cause framework. These forms of antagonism include ‘‘synergy under recoding of an exposure,’’ ‘‘synergism under recoding of the outcome,’’ and so-called ‘‘competing response types,’’ with synergism itself conceived of as causal co-action within the sufficient-cause framework. In this paper,...

It is well established that superior colliculus (SC) multisensory neurons integrate cues from different senses; however, the mechanisms responsible for producing multisensory responses are poorly understood. Previous studies have shown that spatially congruent cues from different modalities (e.g., auditory and visual) yield enhanced responses and that the greatest relative enhancements occur fo...

The ability to detect emotional changes is of primary importance for social living. Though emotional signals are often conveyed by multiple modalities, how emotional changes in vocal and facial modalities integrate into a unified percept has yet to be directly investigated. To address this issue, we asked participants to detect emotional changes delivered by facial, vocal and facial-vocal expre...
