Observation of discontinuities in the periodic modulation of PSR B1828−11 [PDF]
ABSTRACT PSR B1828–11 is a radio pulsar that undergoes periodic modulations (∼500 d) of its spin-down rate and beamwidth, providing a valuable opportunity to understand the rotational dynamics of neutron stars. The periodic modulations have previously been attributed to planetary companion(s), precession, or magnetospheric effects and ...

Discontinuous Modulation Scheme for a Differential-Mode Ćuk Inverter [PDF]
The differential-mode Cuk inverter (DMCI) is a single-stage inverter with low device count. It offers advantages over other topologies because of compactness, higher power density, and reduced cost. It is a promising topological configuration for renewable-/alternative-energy applications with isolated as well as nonisolated structures.
