Abstract: A defined peak region residing between about 3.2 and 3.4 ppm of a proton NMR spectrum of an in vitro biosample is electronically evaluated to determine a level of trimethylamine-N-oxide (“TMAO”). The biosample may be any suitable biosamples including human serum with a normal biologic range of between about 1-50 ?M or urine with a normal biologic range of between about 0-1000 ?M.

Abstract: Logical rules can be automatically generated for use with event detection systems according to some aspects of the present disclosure. For example, a computing device can extract a group of logical rules from trained decision trees and apply a test data set to the group of logical rules to determine count values corresponding to the logical rules. The computing device can then determine performance metric values based on the count values, select a subset of logical rules from among the group of logical rules based on the performance metric values, and provide at least one logical rule in the subset for use with an event detection system. The event detection system can be configured to detect an event in relation to a target data set that was not used to train the decision trees.

Abstract: Malicious activity can be detected and prevented in real-time or otherwise. For example, a system of the present disclosure can receive a request from a user to obtain access to an entity, determine data objects based on the request, and access data-object network definitions corresponding to the determined data objects. The system can also receive a profile for the user indicating behavioral information relating to the user. The system can then determine a likelihood that the request is associated with malicious activity based on (i) the data objects, (ii) the profile, and (iii) the data-object network definitions. The system can allow or deny the user access to the entity based on the likelihood that the request is associated with malicious activity.

Abstract: A method and kit for the optical detection of proteins and nucleic acids in a matrix, such as polyacrylamide electrophoresis gels. The method comprises fixing the proteins and nucleic acids in the matrix using aromatic sulfonic acids having tertiary amines capable of forming coordination complexes with silver ion.
