Bridge effect in charge transfer absorption bands. para-substituted benzylideneacetones
(Marcel Dekker Inc., 1996)
The electronic absorption charge transfer bands in a series of para-substituted benzalketones are analyzed in order to stablish the role of the electron-donor substituent as well as the electronic properties of the molecular ...
Photonic flat band dynamics
(Taylor & Francis, 2021)
During the last decades, researchers of different scientific areas have investigated several systems and materials to suggest new ways of transporting and localizing light. These problems are probably main goals in any ...

Back extensor muscle fatigue at submaximal workloads assessed using frequency banding of the electromyographic signal
(Elsevier B.V., 2011-12-01)
Background: Changes in the mean or median frequency of the electromyographic (EMG) power spectrum are often used to assess skeletal muscle fatigue. A more global analysis of the spectral changes using frequency banding may ...
