Stripe formation in bacterial systems with density-suppressed motility
Stripe formation bacterial systems density-suppressed motility Biological Physics
2012/5/3
Engineered bacteria in which motility is reduced by local cell density generate periodic stripes of high and low density when spotted on agar plates. We study theoretically the origin and mechanism of...
Macroscopic loop formation in circular DNA denaturation
Macroscopic loop formation circular DNA denaturation Biomolecules Statistical Mechanics
2012/5/3
The statistical mechanics of DNA denaturation under fixed linking number is qualitatively different from that of the unconstrained DNA. Quantitatively different melting scenarios are reached from two ...
Pattern formation in a cell based auxin transport model with numerical bifurcation analysis
Pattern formation cell auxin transport model numerical bifurcation analysis
2012/2/28
Transport models of growth hormones can be used to reproduce the hormone accumulations that occur in plant organs. Mostly, these accumulation patterns are calculated using time step methods, even thou...
Formation of BCR Oligomers Provides a Mechanism for B cell Affinity Discrimination
Formation BCR Oligomers Provides Mechanism B cell Affinity Discrimination
2012/2/28
B cells encounter antigen over a wide affinity range. The strength of B cell signaling in response to antigen increases with affinity, a process known as "affinity discrimination". In this work, we us...
New insight into kinetics behavor of the structural formation process in Agar gelation
kinetics behavor structural formation process Agar gelation
2011/8/17
Abstract: A time-resolved experimental study on the kinetics and relaxation of the structural formation process in gelling Agar-water solutions was carried out using our custom-built torsion resonator...
Formation and Stability of Synaptic Receptor Domains
Formation Stability Synaptic Receptor Domains
2011/1/5
Neurotransmitter receptor molecules, concentrated in postsynaptic domains along with scaffold and a number of other molecules, are key regulators of signal transmission across synapses. Employing expe...
