A metafilm is a type of metasurface---a two-dimensional equivalent of a metamaterial, and is essentially a surface distribution of electrically small scatterers
Seismic risk has social and physical aspects: although very different in nature, they are intertwined and share striking similarities. Seismic risk assessment
Oxidatively induced DNA damage is caused by endogenous and exogenous sources in living organisms. Many resulting DNA lesions are mutagenic and lead to mutations

This review endeavors to summarize the past 40 years or so of progress towards the development of mathematical models for understanding and predicting cement
Reliable experimental demonstrations of violations of local realism are highly desirable for fundamental tests of Quantum Mechanics. Such violations can be
Background: We present an approach to cell image databasing that is compatible with searching across a global federation of independent image databases. The
