Growth rates for persistently excited linear systems [PDF]

open access: yes, 2013
We consider a family of linear control systems $\dot{x}=Ax+\alpha Bu$ where $\alpha$ belongs to a given class of persistently exciting signals. We seek maximal $\alpha$-uniform stabilisation and destabilisation by means of linear feedbacks $u=Kx$.

Greenhouse gas growth rates [PDF]

open access: yesProceedings of the National Academy of Sciences, 2004
We posit that feasible reversal of the growth of atmospheric CH 4 and other trace gases would provide a vital contribution toward averting dangerous anthropogenic interference with global climate. Such trace gas reductions may allow stabilization of atmospheric CO 2 at an achievable level of ...

Effect of bacterial growth rate on bacteriophage population growth rate [PDF]

open access: yesMicrobiologyOpen, 2017
AbstractIt is important to understand how physiological state of the host influence propagation of bacteriophages (phages), due to the potential higher phage production needs in the future. In our study, we tried to elucidate the effect of bacterial growth rate on adsorption constant (δ), latent period (L), burst size (b), and bacteriophage population ...

A Real-Time Multiplexed Microbial Growth Intervalometer for Capturing High-Resolution Growth Curves

open access: yesFrontiers in Microbiology, 2019
Batch cultures are a low maintenance and routine culturing method in microbiology. Automated tools that measure growth curves from microorganisms grown in traditional laboratory glassware, such as Balch-type tubes, are not commercially available.
