  • Patent number: 9081626
    Abstract: A method, apparatus, and computer readable medium are provided. According to an embodiment of the invention, a method includes, translating source code written in a first language into source code written in an intermediary language. The method further includes converting the source code written in the intermediary language into source code written in a second language by applying contextual recognition and reconstruction to the source code written in the intermediary language to generate the source code written in the second language. The method further includes prompting a user to customize the conversion of the source code written in the intermediary language into the source code written in the second language.

  • Patent number: 9040249
    Abstract: Methods and reagents are provided for determining the activation state of a signal transduction pathway signaling protein. There exists a need in the art for methods that can monitor the efficacy of a signal transduction inhibitor in a patient. Other needs exist for detecting and monitoring certain disease or disorders that are associated with aberrant activation of a signal transduction pathway signaling protein. The present assay provides a highly sensitive assay that is also useful in patient populations in which obtaining a large cellular sample is difficult, for example, neonates.

  • Patent number: 7882187
    Abstract: A system and method of detecting undesired email containing image-based messages employs a statistical analysis process which identifies and assigns probability values to the presence of each of a pre-selected set of text-related characteristics of an email under consideration and to the presence of each of a pre-selected set of image-related characteristics of the email under consideration. The identified characteristics and their associated probability values are used to determine whether the email is undesired. In one embodiment, the identification and assignment of probability values is a Bayesian analysis and, preferably, a Statistical Token Analysis. The system and method can identify undesired emails which contain images having messages, generally in the form of text in the image.
