This chapter addresses the topic of how embodied neural agents coordinate together to exhibit interesting social behaviors. Embodied neural agents are defined in this Introduction. Sections 2 through 5 describe simulations of collective phenomena emerging from the interactions among embodied neural agents living in the same environment. Section 2 discusses spatial aggregation and proto-social b...

The uctuation dynamics in steady state fragmentation and aggregation processes is analyzed from a kinetic point of view. The uctuations n(x; t) in the number of particles of size between x and x + x, in a sample with average occupation number N(x), appear to behave like sums of uncorrelated events: < n(x; t) 2 >/ N(x). The implications of this fact for the applicability of a mean eld descriptio...

The status and possible roles of propagated waves occurring during vertebrate embryogenesis are discussed. Some preliminary data for waves observed in time-lapse films of early chick (Gallus domesticus) and Medaka (Oryzias latipes, a teleost) are given. The general similarities between these phenomena and wave propagation during cellular slime mold aggregation are pointed out and it is suggeste...

Much is known about diffusion-limited growth from a dilute suspension. The simplest and most famous model is diffusion-limited aggregation (DLA), in which random walkers are released one-by-one far away and become frozen where they first touch a growing fractal cluster. Real growth phenomena, such as mineral deposition in rocks, however, often involve multiple processes, such as advection-diffu...

Organizational modeling gains importance in the development of multi-agent systems, both for modeling and simulation of phenomena in social science and economics, as for developing complex systems to support, e.g., virtual enterprises. This paper contributes to these efforts an analysis and example formalizations and simulation of cause and effect of organizational change. Causes of change are ...

the aggregation of protein is the most prevalent and the most disturbing kind of instability and this challenge exists in almost every stage of the development of protein drug. the presence of insoluble aggregations in protein drugs will make the supply of the product a tough job. this study identifies the inhibition of the folded interferon beta 1-b’s aggregation with the assistance of some ex...

epidemiologic studies show that the cardiovascular diseases are associated with multiple factors such as raised serum total cholesterol, increased ldl, increased platelet aggregation, hypertension and smoking. in-vitro studies have confirmed the ability of some plants of allium species to reduce these parameters. therefore, we evaluated anti-platelet aggregation effect of some allium species (a...

background and objective: nitric oxide (no) plays a role in thermoregulation and growth of protozoa. this work aimed to add the molecule no in physiology of protozoa in contact with abused narcotic substances. materials and methods: a sedative drug, morphine, was infused into a cell chamber containing paramecia . the cell response to the drug was recorded promptly after drug infusion using a po...

energy consumption is considered as a critical issue in wireless sensor networks (wsns). batteries of sensor nodes have limited power supply which in turn limits services and applications that can be supported by them. an efcient solution to improve energy consumption and even trafc in wsns is data aggregation (da) that can reduce the number of transmissions. two main challenges for da are: (i)...
