Anomalies as obstructions: from dimensional lifts to swampland

Abstract We revisit the relation between the anomalies in four and six dimensions and the Chern-Simons couplings one dimension below.While the dimensional reduction of chiral theories is well-understood, the question which three and five-dimensional theories can come from a general circle reduction, and are hence liftable, is more subtle.We argue t

Newer protocols and future in collagen cross-linking

Corneal Cross-Linking (CXL) is an established surgical procedure for the treatment of corneal disorders such as corneal ectasia and keratoconus.This method of treatment stabilises the corneal structure and increases rigidity, reducing the requirement for corneal puddles the platypus chocolate transplantation.Since its development, many scientific s

Trends in the evolution of ecology: “Spain is different”

During the last fifty years ecology has matured as a scientific discipline.In this paper I analyse the temporal development of the paradigm based on physical systems (the ecosystem paradigm), and the evolutionary ecology paradigm.I first analyse the contents of 61 textbooks to calculate the relative importance of ecosystem and evolutionary ecology
