DOI: 10.1093/mnras/sty2823
Abstract: The high mass X-ray binary Cepheus X-4, during its 2014 outburst, showed evidence for an asymmetric cyclotron line in its hard X-ray spectrum. The 2014 spectrum provides one of the clearest cases of an asymmetric… read more here.

DOI: 10.1109/tcsii.2018.2863698
Abstract: Pulse train (PT) control has the advantages of simple structure, fast transient response, low cost, and free compensation network. However, for the power converters operated in continuous conduction mode, undesired low-frequency oscillation of output voltage… read more here.
