Despite neither brain nor central control, they behave as a whole. The relation between parts and whole is needed to attack this problem because the collective behavior emerges through the interplay between individuals and the whole collective. However, the bridge between individuals and whole collective remains an open question. Recently, more accurate analysis of flocking behaviour has become possible. Cavagna and others found that fluctuations in a flock show the sizes of spatial correlations scales linearly with the size of the flock. They called this scale-invariant coherence of fluctuations "scale-free correlation." We suggest, in this paper, that scale-free correlation fills the gap between individuals' and whole flocks' movement. In a previous study, our model (metric-topological interaction model) succeeded in explaining "scale-free correlation." In this study, the MTI model shows the self-similarity of internal fluctuations and 1/ƒ fluctuation. We also show that these critical fluctuations in MTI flocks lead to flock dividing. From these results, we discuss the possibility of internal fluctuations that contribute to smooth movement as a whole flock, despite having the risk of collapsing itself.

This research inspects a relationship of these two relationships in Japanese plays. At first we make two series of lattices from the rough set to show figure and ground relationships in each scene. One series are made by verbs mentioned in speech. These are defined as "type-verbs". Another are made by verbs actually did in play by some characters. These are defined as "token-verbs". Compared change of complementarity and non-distributivity of lattices about type and token verbs, in short plays two series of complementarity differ beginning to ending but in long plays they accord in ending.

Human consciousness has long been studied, with various models being developed, and the discussion still continues today. Originally generated for visual perception, gestalt psychology introduced the idea of figure and ground to describe our mechanism of attention. We have come up with a method to model such figure and ground relation. We have applied this method to model how a figure and ground relation may be applied to story characters when reading a literary work. We compared this result with a control resulting from randomly generated input matrix. The resulting graph generated from text has characteristics changes. The changes in the graph reflect a dramatic shift in character attributes. Such drama may encourage the reader to anticipate what comes next in the story.

Following our previous study, we investigated how the tubular structure of the plasmodium affects the cell motility. From a series of experimental results, it was indicated that the cell motility and consequent morphogenesis is dependent on the locomotive history of the plasmodium. We thus propose the presence of memory reservoir in the cellular organism, and discuss how such aspect is related to computing anticipatory systems.

Rough set driven lattice is a suitable tool for analyzing subjective phenomenon such as reading because 1) it produces Boolean as well as non-Boolean lattices that reflect the input information, and 2) this method requires two interpretations of a target, such as subject and attribute, which a sentence provides. By using this method, we can compare how a logical structure resulting from reading with anticipation is different from the information revealed by the actual text. The difference is quantified by complement properties of a lattice, through complementarity and non-distributivity.

A colimit of the dynamical system corresponds to a set of pairs of an initial state and a final state. Expansion of the colimit based on a concept of internal measurement induces heterarchical structure in the dynamical system and derives interaction between the system and the other one. Dynamical change of potential functions derived from that expansion is relevant to a concept of emergence based on the viewpoint of the Hamiltonian system.

On-off intermittency is aperiodic switching motion between laminar phases and burst phases. It is observed in critical points with blowout bifurcation. Occurrence of it is sensitive with respect to parameter shifts in conventional systems. In the present paper, an extended dynamical system with an interaction between a global structure and a local motion is proposed. This interaction means a reciprocal definition between a parameter and state variables. The reciprocal definition is induced from the concept of a generative pointer that suggests an extended subobject classifier. Ubiquitous on-off intermittency is observed for a wide range of parameter values when a generative pointer is applied to a Henon map. This fact implies robustness of on-off intermittency against parameter shifts.

Trophic level networks are described by directed graphs. Their properties are surveyed in terms of an adjunction on a subcategory of the category of directed graphs. In particular, it is shown that trophic level networks are invariant under the composition of the right adjoin functor and the left adjoin functor. This invariance of trophic level networks can be broken by introducing the notion of time into the left adjoint functor. This leads to changes in trophic level networks. We show that the left adjoin functor consists of an intra-level process and an inter-level process. An inconsistency between them arises by the introduction of time. Negotiation between the intra-level process and the inter-level process can resolve the inconsistency at a level, however, a new inconsistency can arises at an emerged new level. Thus our algebraic description can follow indefinite development of trophic hierarchy.

In previous accounts both the moving object and flashing stimuli are unconditionally believed as something to be recognized. In this study, we conducted several experiments for FLE involved the problem of segregation between figure and ground. We found that interaction between moving objects and flashing stimuli as compatibility and complementarity of figure/ground effectively influences FLE. The results show us one aspect of the temporal perception, so that the subjective segregation between internal (as figure) and external (as ground) recognition would drive the time.

We, however in this paper, propose a formal system based on pseudo-reductionism. In the system which we propose, each object is variable, and can accumulate information by virtue of the variableness itself. The accumulated information can be exposed afterward. We apply this new concept to the transition of a directed graph, which can be regarded as monologue. In addition, also apply to dialogue-based society model which we already proposed. The dialogue in the model is based on monologues of autonomous agents. Thu, 29 Aug 2024 14:02:54 +0200 Thu, 29 Aug 2024 14:03:00 +0200 http://popups.lib.uliege.be/1373-5411/index.php?id=2556
