... The discovery of this radiopulsar is potentially important not only for confirming the theory of evolution of NS, but also for understanding processes occurring in stellar winds   from normal stars. After all, a radiopulsar orbiting in the semi-transparent stellar wind of a normal star is a sort of probe scanning an inhomogeneous plasma by pulsed radiation (Lipunov and Prokhorov, 1984)[ 110 ]. ... 1) absorption of radio waves (light curve); . ... This object is a radiopulsar orbiting a Be-star. ...

The technical memorandum: A Kernel Model for Precision Timekeeping (PostScript) describes an engineering model which implements a precision time-of-day function for a generic operating system. ... The model changes the way the system clock is adjusted in time and frequency, as well as provides mechanisms to discipline its time and frequency to an external precision timing source, such as a pulse-per-second (PPS) signal. ...
