Advances in the measurements of the mass attenuation coefficients
The knowledge of atomic fundamental parameters, such as mass attenuation coefficients or fluorescence yields with low uncertainties, is of decisive importance in elemental quantification involving X‐ray fluorescence analysis techniques. Several databases providing the mass attenuation coefficients are accessible and frequently used within a large ...

Wave attenuation at a salt marsh margin: A case study of an exposed coast on the Yangtze estuary [PDF]
To quantify wave attenuation by (introduced) Spartina alterniflora vegetation at an exposed macrotidal coast in the Yangtze Estuary, China, wave parameters and water depth were measured during 13 consecutive tides at nine locations ranging from 10 m ...

An inequality for longitudinal and transverse wave attenuation coefficients [PDF]
Total absorption, defined as the net flux of energy out of a bounded region averaged over one cycle for time harmonic motion, must be non-negative when there are no sources of energy within the region. This passivity condition places constraints on the non-dimensional absorption coefficients of longitudinal and transverse waves, γL and γT, in isotropic

Imaging the attenuation coefficients of positron beams in matter: positron attenuation tomography [PDF]
A new positron annihilation imaging modality is described that enables nondestructive measurement of the linear attenuation coefficients (LACs) of positron beams in heterogeneous materials. This positron attenuation tomography (PAT) technique utilizes a positron emission tomography (PET) system embedded within a uniform static magnetic field, such as ...
