Proteins might misfold during translation and folding or even once they are in their native states, due to stochastic fluctuations, destabilizing mutations or cellular stress. Aberrant protein species are usually detected and either refolded or cleared by the protein quality control machinery (Ciechanover and Kwon, 2015). When misfolded protein conformers cannot be degraded, they tend to self-assemble to form aggregates, a characteristic of many neurodegenerative diseases.

This paper is focused on the automated synthesis of wideband bandpass filters operating at microwave frequencies and based on electromagnetic bandgap(EBG)*** classical counterpart of such filter consists of a combination of transmission line sections and shunt-connected grounded stubs placed at equidistant *** replacing the transmission line sections with capacitively-loaded lines(a kind of EBG-based lines)exhibiting the same phase shift at the lower cutoff frequency and the same characteristic(actually Bloch)impedance,filter size is reduced and the spurious pass bands can be efficiently *** practice,the loading capacitances are implemented by means of patches,in order to achieve a fully planar filter *** presence of the patches reduces the effective phase velocity of the capacitively-loaded lines,thus providing a slow-wave effect useful for filter ***,due to periodicity,such EBG-based lines exhibit wide stop bands,which are used for spurious *** though such EBGbased filters were previously reported by some of the authors,a systematic synthesis method was not applied for filter *** this paper,the main aim is to demonstrate the potential of aggressive space mapping(ASM)for that purpose,and it will be shown that such filters can be automatically synthesized.
