In this expository paper we show how one can, in a uniform way, calculate the weight distributions of some well-known binary cyclic codes. The codes are related to certain families of curves, and the weight distributions are related to the distribution of the number of rational points on the curves.

Radio pulsar observations can be used to test aspects of general relativity from equivalence principle violations to binary orbital effects in the strong-field regime. This article summarizes the status of such tests at the start of the meeting, and describes two new tests made possible by recent observations of well-known binary pulsar systems.

Introduction: LiF dosimeter has the most application in medicine. This study aimed to evaluate some dosimetric properties of a novel LiF: Mg, Ti. Materials and Methods: An ELEKTA Precise linear accelerator was used to calibrate dosimeters at 6 MV. In this survey, responses of dosimeters were evaluated up to 1000 cGy. Background effect was investigated in two different dosimeter states includin...
