La carne impassibile

about to Oxford pathology when he arrived in 1935, developing a whole new programme of teaching and research and continuing it long after the penicillin story was all over bar the squabbles about priorities. Florey's characteristics, of objective honesty, research flair, and prodigious industry and technical skill, were partly innate and partly developed in earlier posts, including those at Lon...

Carne–varopoulos Bounds for Centered Random Walks

Short title: Centered random walks Abstract: we extend the Carne-Varopoulos upper bound on the probability transitions of a Markov chain to a certain class of non-reversible processes by introducing the definition of a ‘centering measure’. In the case of random walks on a group, we study the connections between different notions of centering.

Generalized admittance matrix models of OTRAs and COAs

This paper proposes new admittance matrix models to approach the behavior of fully-differential Operational Transresistance Amplifiers (OTRAs) and Current Operational Amplifiers (COAs). The infinity-variables method is used in order to derive the new generalized models. As a consequence, standard nodal analysis being improved to compute fully-symbolic small-signal characteristics of fullydiffer...
