101. Reading Sequences of Interspike Intervals in Biological Neural Circuits - Abarbanel, Henry D. I.; Talathi, Sachin
We address the question: How do neural circuits recognize and read these ISI sequences.

102. Shock waves in virus fitness evolution - Carvalhaes, Fernando G.; Goldman, Carla
We consider a nonlinear partial differential equation of conservation type to describe the dynamics of vesicular stomatitis virus observed in aliquots of fixed particle number taken from an evolving clone at periodic intervals of time \cite{novella 95}.

103. Master equation approach to the assembly of viral capsids - Keef, T.; Micheletti, C.; Twarock, R.
The distribution of inequivalent geometries occurring during self-assembly of the major capsid protein in thermodynamic equilibrium is determined based on a master equation approach.

104. Assembly Models for Papovaviridae based on Tiling Theory - Keef, T.; Taormina, A.; Twarock, R.
Assembly models are developed for viral capsids built from protein building blocks that can assume different local bonding structures in the capsid.

105. A Modified Iterative IOM Approach for Optimization of Biochemical Systems - Xu, Gongxian; Shao, Cheng; Xiu, Zhilong
The presented previously indirect optimization method (IOM) developed within biochemical systems theory (BST) provides a versatile and mathematically tractable optimization strategy for biochemical systems.

106. Should you believe that this coin is fair? - Bialek, William
Faced with a sequence of N binary events, such as coin flips (or Ising spins), it is natural to ask whether these events reflect some underlying dynamic signals or are just random.

107. Quasispecies can exist under neutral drift at finite population sizes - Forster, Robert; Adami, Christoph; Wilke, Claus O.
We investigate the evolutionary dynamics of a finite population of RNA sequences adapting to a neutral fitness landscape.

108. Equation of state of looped DNA - Kulic, I. M.; Mohrbach, H.; Thaokar, R.; Schiessel, H.
We calculate the equation of state of DNA under tension for the case that the DNA features loops.

109. Networks of Mobile Elements for Biological Systems - Thadani, Kanchan; Ashutosh
In this paper we present a network model to study the impact of spatial distribution of constituents, coupling between them and diffusive processes in the context of biological situations.

110. High resolution protein folding with a transferable potential - Hubner, Isaac A.; Deeds, Eric J.; Shakhnovich, Eugene I.
A generalized computational method for folding proteins with a fully transferable potential and geometrically realistic all-atom model is presented and tested on seven different helix bundle proteins.

111. Mathematical modeling of evolution of horizontally transferred genes - Novozhilov, Artem S.; Karev, Georgy P.; Koonin, Eugene V.
We describe a stochastic birth-and-death model of evolution of horizontally transferred genes in microbial populations.

112. In silicio stretching of chromatin - Aumann, Frank; Lankas, Filip; Caudron, Maiwen; Langowski, Jörg
The model approximates the DNA by a flexible polymer chain with Debye-H\"uckel electrostatics and uses a two-angle zig-zag model for the geometry of the linker DNA connecting the nucleosomes.

113. Weighted and unweighted network of amino acids within protein - Aftabuddin, Md.; Kundu, Sudip
The information regarding the structure of a single protein is encoded in the network of interacting amino acids.

114. Embedded transfer RNA Genes - Ghosh, Zhumur; Das, Smarajit; Chakrabarti, Jayprokas; Mallick, Bibekanand; Sahoo, Satyabrata
equitans some of the missing tRNA genes are embedded in others.

115. Universality of Long-Range Correlations in Expansion-Randomization Systems - Messer, Philipp W.; Lassig, Michael; Arndt, Peter F.
We study the stochastic dynamics of sequences evolving by single site mutations, segmental duplications, deletions, and random insertions.

116. Stimulus - response curves of a neuronal model for noisy subthreshold oscillations and related spike generation - Braun, Martin Tobias Huber And Hans Albert
We investigate the stimulus-dependent tuning properties of a noisy ionic conductance model for intrinsic subthreshold oscillations in membrane potential and associated spike generation.

117. Some protein interaction data do not exhibit power law statistics - Tanaka, Reiko; Yi, Tau-Mu; Doyle, John
It has been claimed that protein-protein interaction (PPI) networks are scale-free based on the observation that the node degree sequence follows a power law.

118. Domesticated P elements in the Drosophila montium species subgroup have a new function related to a DNA binding property - Reiss, Daphné; Nouaud, Danielle; Ronsseray, Stéphane; Anxolabéhère, Dominique
Molecular domestication of a transposable element is defined as its functional recruitment by the host genome.

119. Speciational view of macroevolution: are micro and macroevolution decoupled? - Schwammle, V.; Brigatti, E.
A statistical analysis of the so generated evolutionary tree captures realistic features showing power laws for frequency distributions in time and size.

120. Age-Associated Disorders As A Proxy Measure Of Biological Age: Findings From the NLTCS Data - Kulminski, A.; Yashin, A.; Ukraintseva, S.; Akushevich, I.; Arbeev, K.; Land, K.; Manton, K.
Background: The relative contribution of different aging-associated processes to the age phenotype may differ among individuals, creating variability in aging manifestations among age-peers.
