Emergence of robust growth laws from optimal regulation of ribosome synthesis

open access: yesMolecular Systems Biology, 2014
Bacteria must constantly adapt their growth to changes in nutrient availability; yet despite large‐scale changes in protein expression associated with sensing, adaptation, and processing different environmental nutrients, simple growth laws connect the ...

Gaussian Sum-Rules and Prediction of Resonance Properties [PDF]

open access: yes, 2000
Techniques for using Gaussian QCD sum-rules to predict hadronic resonance properties are developed for single-resonance and two-resonance phenomenological models, and criteria are developed for determining which of these models is required for analyzing ...

Comparison Between Phenomenological and Fiber-Section Non-linear Models

open access: yesFrontiers in Built Environment, 2020
The prediction of the seismic response of structures requires accurate models for describing the behavior of each structural element. In frame analysis, non-linearities are typically modeled through either lumped or distributed plasticity elements ...

Phenomenological modeling of geometric metasurfaces

open access: yesOptics Express, 2016
Metasurfaces, with their superior capability in manipulating the optical wavefront at the subwavelength scale and low manufacturing complexity, have shown great potential for planar photonics and novel optical devices. However, vector field simulation of metasurfaces is so far limited to periodic-structured metasurfaces containing a small number of ...
