Most of the Spanish media have portrayed Catalan independentism as nationalism and populism. This article argues that this political and social mobilization does not fit into the usual definitions of populism as anti-elitist, anti-liberal and anti-pluralistic movement. Catalan independentism is here interpreted by stressing its democratic features, namely as a form of democratic populism: horizontally organized, and critical of procedural safeguards and counter-majoritarian powers. The popular organization of the referendum on 1 October 2017 and the vigorous democratic experience by almost half of the population of Catalonia allow for a characterization of this populism as a hybrid phenomenon that includes bottom-up and top-down dynamics, thereby contrasting with the usual leader-centred understanding of populism.

Characterization of circadian systems at the organism level—a top-down approach—has led to definition of unifying properties, a hallmark of the science of chronobiology. The next challenge is to use a bottom-up approach to show how the molecular workings of the cellular circadian clock work as building blocks of those properties. We review new studies, including a recently published PLOS Biology paper by Nikhil and colleagues, that show how programmed but also stochastic generation of variation in cellular circadian period explain important adaptive features of entrained circadian phase.

In this study, experimental results on mesoporous zeolite preparation from a common solid waste, the rice husk ash by a top-down and bottom-up approach were reported. In top-down method, the consecutive treatments of zeolite by acid and alkaline in the presence of a cationic surfactant (CTAB) successfully generated mesopores in the zeolite. In bottom-up method, the sufficient added amount of CTAB in the gel composition could form mesopores in the zeolite. The obtained mesoporous zeolite possessed mesopore with a size of around 3-6 nm in both top-down and bottom-up approaches. As a result, the pore volume of the mesoporous zeolite was significantly increased by more than 60% when comparing to the “parent” rice-husk-ash derived zeolite. Significantly, the mesopore surface area of the mesoporous zeolite could be 2.4 times higher than that of the parent zeolite.
