Self‐centering structural systems with combination of hysteretic and viscous energy dissipations [PDF]
Earthquake Engineering & Structural Dynamics, 2010 AbstractThis paper presents an innovative set of high‐seismic‐resistant structural systems termed Advanced Flag‐Shaped (AFS) systems, where self‐centering elements are used with combinations of various alternative energy dissipation elements (hysteretic, viscous or visco‐elasto‐plastic) in series and/or in parallel.

The immune system as a self-centered network of lymphocytes [PDF]
Immunology Letters, 2015 This essay makes a brief historical and comparative review of selective and network theories of the immune system which is presented as a chemical sensory system with immune and non-immune functions. The ontogeny of immune networks is the result of both positive and negative selection of lymphocytes to self-epitopes that serve as a "template" for the ...
