Feedback Amplifier Analysis: Extending the Rosenstark Method for Impedance and Noise Evaluation

We present a flexible mathematical method that extends the Rosenstark method and enables the analysis of any electrical network with feedback and all its key parameters such as gain, frequency response, input/output impedances, and noise. Unlike the original Rosenstark method, the proposed approach provides a unified procedure that can be universally applied without the need of additional steps (like Blackman’s theorem) to fully characterize the network. Our approach inherits the same advanta...

Genomically integrated cassettes swapping: bringing modularity to the strain level in Saccharomyces cerevisiae

A large variety of synthetic biology toolkits for the introduction of multiple expression cassettes is available for Saccharomyces cerevisiae. Unfortunately, none of these tools is designed to allow the modification - exchange or removal - of the cassettes already integrated into the genome in a standardized way. The application of the modularity principle therefore ends to the steps preceding the final host engineering, making microbial cell factories construction stiff and strictly sequenti...

Assembling urban regeneration: The case of NoLo in Milan

The regeneration of cities lies in the middle of processes that intersect bottom-up and top-down dynamics in increasingly complex ways. The case of the partially gentrifying NoLo (North of Loreto) neighbourhood, in Milan (Italy), is emblematic from this point of view: it shows the development of a specific urban area under the impulse of contrasting dynamics in which various social actors negotiate unstable positions. The article will propose to scrutinise these tensions through an ethnograph...
