The code comparison technology plays an important role in the fields of software security protection and plagiarism detection. Nowadays, there are mainly FIVE approaches of plagiarism detection, file-attribute-based, text-based, token-based, syntax-based and semantic-based. The prior three approaches have their own limitations, while the technique based on syntax has its shortage of detection a...

We calculate the three loop gauge β-function for an abelian N = 1 supersymmetric gauge theory, using DRED. We construct a coupling constant redefinition that relates the result to the corresponding term in the NSVZ β-function, and by generalising this redefinition to the non-abelian case we derive the DRED three loop gauge β-function for the non-abelian case.

Current use of inheritance has illustrated that the introduction of conceptual inconsistencies is possible in a class hierarchy. This paper discusses the reasons why complete method redefinition infringes the essence of inheritance. A redefinition metric set is proposed and practical experiments demonstrate that the results obtained permit the detection of inheritance design problems. Appropria...

We have recovered four new records of the paleomagnetic field variability within Oxygen Isotope Stage 5 from deep-sea sediment cores of the Blake/Bahama Outer Ridge, western North Atlantic Ocean. These cores contain reproducible evidence of the Blake Event and are located within 300 km of cores used by Smith and Foster (1969) to define the Blake Event. Our new paleomagnetic records have both re...
