Temporal gene expression and regulation in T4 phage af Levine, Mandara Alexis

“...Collectively, transcriptional and translational controls lead to precisely tuned protein synthesis rates during infection, as exemplified by the phenomenon that components of T4 protein complexes are synthesized according to their stoichiometry— a principle that has been observed in organisms during steady-state growth. ...”

Synthetic incoherent feedforward circuits show adaptation to the amount of their genetic template af Bleris, Leonidas, Xie, Zhen, Glass, David, Adadey, Asa, Sontag, Eduardo, Benenson, Yaakov

“...Natural and synthetic biological networks must function reliably in the face of fluctuating stoichiometry of their molecular components. These fluctuations are caused in part by changes in relative expression efficiency and the DNA template amount of the network-coding genes. ...”

Non-Gated Laser Induced Breakdown Spectroscopy Provides a Powerful Segmentation Tool on Concomitant Treatment of Characteristic and Continuum Emission af Myakalwar, Ashwin Kumar, Dingari, Narahara Chari, Dasari, Ramachandra Rao, Barman, Ishan, Gundawar, Manoj Kumar

“...While use of such a system introduces substantive continuum background in the spectral dataset, we show that appropriate treatment of the continuum and characteristic emission results in accurate discrimination of pharmaceutical formulations of similar stoichiometry. Specifically, our results suggest that near-perfect classification can be obtained by employing suitable multivariate analysis on the acquired spectra, without prior removal of the continuum background. ...”
