In recent years experiments have demonstrated that living cells can measure low chemical
concentrations with high precision, and much progress has been made in understanding …

A number of approaches for discretizing partial differential equations with random data are
based on generalized polynomial chaos expansions of random variables. These constitute …

DNA-based machines that walk by converting chemical energy into controlled motion could
be of use in applications such as next-generation sensors, drug-delivery platforms and …

Collective cell responses to exogenous cues depend on cell–cell interactions. In principle,
these can result in enhanced sensitivity to weak and noisy stimuli. However, this has not yet …

Recent single-cell experiments have revived interest in the unavoidable or intrinsic noise in
biochemical and genetic networks arising from the small number of molecules of the …

In many cellular signaling pathways, key components form clusters at the cell membrane.
Although much work has focused on the mechanisms behind such cluster formation, the …

Gradient sensing requires at least two measurements at different points in space. These
measurements must then be communicated to a common location to be compared, which is …

Signal-processing molecules inside cells are often present at low copy number, which
necessitates probabilistic models to account for intrinsic noise. Probability distributions have …

In the last 10 years, laser-driven fusion experiments performed on atomic clusters of deuterium
have shown a surprisingly high neutron yield per joule of input laser energy. Results …

A device that uses ultrasonic atomization of a liquid to produce an aerosol of micron-scale
droplets is described. This device represents a new approach to producing targets relevant to …
