Incorporating expression data in metabolic modeling: A case study of lactate dehydrogenase

March 30, 2006

We use data from mRNA expression arrays and chemical kinetics to formulate a metabolic model relevant to K562 erythroleukemia cells.

Controlled irradiative formation of penitentes

March 10, 2006

Spike-shaped structures are produced by light-driven ablation in very different contexts. We report the first laboratory generation of centimeter-scale snow and ice penitentes.

Opening of nucleic-acid double strands by helicases: Active versus passive opening

Jan. 19, 2005

his paper presents a theoretical study of the coupling between helicase translocation and nucleic acid unwinding.

Collapsing bacterial cylinders

Dec. 31, 2001

Under special conditions bacteria excrete an attractant and aggregate. The high density regions initially collapse into cylindrical structures, which subsequently destabilize and break up into spherical aggregates.

Formation of structure in snowfields motivated by penitentes, suncups, and dirt cones

Nov. 30, 2001

Penitentes and suncups are structures formed as snow melts, typically high in the mountains. When the snow is dirty, dirt cones and other structures can form instead.
