Biofilms dominate microbial life in numerous aquatic ecosystems, and in engineered and medical systems, as well. The formation of biofilms is initiated by single primary cells colonizing surfaces from the bulk liquid.

Entropy Related to K-Banhatti Indices via Valency Based on the Presence of C6H6 in Various Molecules
Entropy is a measure of a system’s molecular disorder or unpredictability since work is produced by organized molecular motion. Shannon’s entropy metric is applied to represent a random graph’s variability.

IMAGE BASED MULTI-LENGTH RANDOM KEY GENERATOR
Random Number Generators (RNGs) are an important building block for algorithms and protocols in cryptography. They are dominant in the construction of encryption keys and other cryptographic algorithm parameters.

Hyperuniformity of generalized random organization models
Studies of random organization models of monodisperse spherical particles have shown that a hyperuniform state is achievable when the system goes through an absorbing phase transition to a critical state. Here we investigate to what extent hyperuniformity is preserved when the model is generalized to particles with a size distribution and/or ...

Random hierarchies that facilitate self-organization [PDF]
Since it is widely accepted that self-organization is difficult to achieve using constructive or centrally run algorithms, a random hierarchy is proposed that intrinsically facilitates self-organization. The random hierarchy consists of each node in the network independently choosing a rank at random such that a mean 2(/spl Delta/-1)/spl Delta//sup i-1/

Theory of Connectivity: Nature and Nurture of Cell Assemblies and Cognitive Computation
Richard Semon and Donald Hebb are among the firsts to put forth the notion of cell assembly – a group of coherently or sequentially-activated neurons– to represent percept, memory, or concept.

Hierarchical motion organization in random dot configurations.
Motion fields differ in the degree to which they can serve as hierarchical frames of reference. To assess the strength of hierarchical motion organisation, we measured the ability of human observers to extract the motion of a target dot relative to a background of moving dots.

A simple deterministic self-organized critical system
We introduce a new continuous cellular automaton that presents self-organized criticality. It is one-dimensional, totally deterministic, without any kind of embedded randomness, not even in the initial conditions.

Effect of Noise on Patterns Formed by Growing Sandpiles [PDF]
We consider patterns generated by adding large number of sand grains at a single site in an abelian sandpile model with a periodic initial configuration, and relaxing. The patterns show proportionate growth.
