In Actor Prolog a resident is a special mechanism that helps processes to inspect state of other processes. A resident observes the state of a specified (target) process and if the state of the process changes (for instance, after message handling) it proves a specified predicate of the process. ... Work of the resident. ... Any change of the list of target processes or arguments of resident function results in activation of the resident and repeated collection of information in the target worlds. ...

Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...
