Micro-computed tomography (micro-CT) is considered an essential tool for characterizing the internal structure of samples in a non-destructive manner. Although micro-CT technology is great for ...

Spectral theory provides a rigorous framework for analysing the eigenvalues and eigenfunctions of differential operators that play an essential role in mathematical physics. In particular, ...

This paper presents a new approach to spectral methods for initial boundary value problems. A filtered version of the partial differential equation and the initial and boundary conditions at an ...

Pioneering approach makes compact, cost-effective, high-resolution multispectral shortwave infrared (SWIR) sensors accessible, enabling broad application in security, agriculture, automotive, ...

In this paper we determine the relationship between the spectra of a continuous contraction semigroup on Hilbert space and properties of the resolvent of its infinitesimal generator. The methods rely ...

Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www ...

Imagine working with special cameras that capture light your eyes can’t even see—ultraviolet rays that cause sunburn or infrared heat signatures that reveal hidden writing. Or perhaps using ...
