Cellular automata in cytoskeletal lattices

Evolving cellular automata to perform computations: mechanisms and impediments

“…In scientific modeling applications, CAs have been used to simulate, for example, magnetic spin systems [15,90], fluid dynamics [21,27], chemical oscillations [53,64], crystal growth [52,65], galaxy formation [30], stellar accretion disks [77], dynamics in cytoskeletal lattices [82], and the formation of biological patterns (e.g., the intricate fractal patterns seen on mollusk shells [11], or vertebrate pigment patterns [92]). Common to all these modeling applications is the belief that CAs can capture essential features of physical systems in which largescale behavior arises from the collective effect of large numbers of locally interacting simple components.…”

The influence of polaron–phonon interaction on absorption spectra in molecular crystals

“…A great deal of these efforts concerns the investigations of the optical properties of MCs. Particular attention has been devoted to the acetanilide (ACN) [2][3][4][5][6][7][9][10][11][12][13][14][15][16]18,19,[22][23][24][25][26], whose hydrogen-bonded structure is similar to that of the molecules of a-helix protein and some molecular crystals with broad application in micro-and opto-electronics [27][28][29][30].…”

Particular attention has been devoted to the acetanilide (ACN) [2][3][4][5][6][7][9][10][11][12][13][14][15][16]18,19,[22][23][24][25][26], whose hydrogen-bonded structure is similar to that of the molecules of a-helix protein and some molecular crystals with broad application in micro-and opto-electronics [27][28][29][30].The focus of the theoretical and experimental work has been the so-called anomalous temperature dependent IR absorption peak in the C-O region (amide-I band at 1650 cm À1 ) and the multiband structure in the N-H region [3][4][5][6][7]26]. Specific temperature properties of the optical spectra of ACN were assigned to the self-trapping (ST) of the quanta of C-O and N-H stretching vibrations [6,7,26].…”

A critical assessment of the information processing capabilities of neuronal microtubules using coherent excitations

“…Classical cellular automata models of MTs based on tubulin dipole transitions, represented as a discrete charge within the tubulin dimer, have demonstrated self-organizing patterns suggesting the potential for MTs to process information [35][36][37]. It has been shown that MT cellular automata networks may signal, adapt, recognize, and subserve neural-level learning [38].…”
