The theoretical study of the effect electron beam parameters, in particular, emittance and its asymmetry on radiation from relativistic electrons undulators is conducted both analytically numerically. reasons for odd even harmonic generation are explored. difference underlying physical spontaneous stimulated harmonics free lasers (FELs) elucidated. generalized forms special functions Bessel Air...

Epidemics in networks can be affected by cooperation in transmission of infection and also connectivity between nodes. An interplay between these two properties and their influence on epidemic spread are addressed in the paper. A particular type of cooperative effects (called synergy effects) is considered, where the transmission rate between a pair of nodes depends on the number of infected ne...
