A protein structural alphabet and its substitution matrix CLESUM - Zheng, Wei-Mou; Liu, Xin
By using a mixture model for the density distribution of the three pseudobond
angles formed by $C_\alpha$ atoms of four consecutive residues, the local
structural states are discretized as 17 conformational letters of a protein
structural alphabet.

Modeling Genetic Networks from Clonal Analysis - Nagarajan, Radhakrishnan; Aubin, Jane E.; Peterson, Charlotte A.
In this report a systematic approach is used to determine the approximate
genetic network and robust dependencies underlying differentiation.
23.
Vibrational energy relaxation in proteins - Fujisaki, Hiroshi; Straub, John E.
An overview of theories related to vibrational energy relaxation (VER) in
proteins is presented.
28.
Synaptic Plasticity with Discrete state synapses - Abarbanel, H. D.; Talathi, S. S.; Gibb, L.; Rabinovich, M.
Experimental observations on synaptic plasticity at individual glutamatergic
synapses from the CA3 Shaffer collateral pathway onto CA1 pyramidal cells in
the hippocampus suggest that the transitions in synaptic strength occur among
discrete levels at individual synapses (~\cite{Peter} and S.

Are scale-free regulatory networks larger than random ones? - Fortuna, Miguel A.; Melian, Carlos J.
Network of packages with regulatory interactions (dependences and conflicts)
from Debian GNU/Linux operating system is compiled and used as analogy of a
gene regulatory network.

Filament depolymerization by motor molecules - Klein, Gernot A.; Kruse, Karsten; Cuniberti, Gianaurelio; Juelicher, Frank
Motor proteins that specifically interact with the ends of cytoskeletal
filaments can induce filament depolymerization.

The Effects of EGF-Receptor Density on Multiscale Tumor Growth Patterns - Athale, Chaitanya A.; Deisboeck, Thomas S.
We studied the effects of epidermal growth factor receptor (EGFR) density on
tumor growth dynamics, both on the sub- and the multi-cellular level using our
previously developed model.
32.
Telomere loss limits the rate of human epithelial tumor formation - Frieboes, Hermann B.; Brody, James P.
Most human carcinomas exhibit telomere abnormalities early in the
carcinogenesis process suggesting that crisis caused by telomere shortening may
be a necessary event leading to human carcinomas.
33.
What can one learn from two-state single molecule trajectories? - Flomenbom, Ophir; Klafter, Joseph; Szabo, Attila
A time trajectory of an observable that fluctuates between two values (say,
on and off), stemming from some unknown multi-substate kinetic scheme, is the
output of many single molecule experiments.
35.
Accelerating, hyper-accelerating, and decelerating probabilistic networks - Gagen, M. J.; Mattick, J. S.
Many growing networks possess accelerating statistics where the number of
links added with each new node is an increasing function of network size so the
total number of links increases faster than linearly with network size.
37.
Pairwise alignment incorporating dipeptide covariation - Crooks, Gavin E.; Green, Richard E.; Brenner, Steven E.
Motivation: Standard algorithms for pairwise protein sequence alignment make
the simplifying assumption that amino acid substitutions at neighboring sites
are uncorrelated.
38.
Stochastic gene expression in switching environments - Gander, Martin; Mazza, Christian; Rummler, Hansklaus
We study a stochastic model proposed recently in the genetic literature to
explain the heterogeneity of cell populations or of gene products.
