Abstract: User login information submitted as part of an attempt to log into a computer system is evaluated for unauthorized or illegitimate use based on indicators of suspicious behavior. Example indicators of suspicious behavior include whether the login information is known to have been compromised, whether the login attempt originates from a network source or a physical source that has previously originated an attempt to log in using login information known to have been compromised, and whether multiple login attempts using the login information from multiple users has originated from the source. A suspicion index can be calculated based on the presence of the indicators of suspicious behavior. The system can require enhanced authentication based on the measurement of suspicious behavior.

Abstract: A system or apparatus for use in downhole communication or detection comprises a downhole arrangement defining a throughbore and primary and secondary elements. One of the primary and secondary elements is provided on the downhole arrangement and the other of the primary and secondary elements is provided in the throughbore. The primary and secondary elements are configurable for coupling of an electromagnetic field therebetween. The primary or secondary element which is provided in the throughbore may be provided on a tool such as a shifting tool which is deployable through the throughbore. The secondary element may be configured to provide the electromagnetic field coupled between the first and second elements with one or more characteristic features. The system may be configured for use, in particular though not exclusively, for communicating information to and/or from a downhole tool in an oil or gas well.

Abstract: A filter for a smoking article has a first filter section comprising a filter material and a smoke modifying additive disposed in an axial region thereof and a second filter section connected to the first filter section and having at least one channel located in an axial region thereof for directing smoke, in use, through the axial region of the first filter section. The smoke modifying additive can comprise a flavourant such as menthol and the second filter section can comprise a tubular section of fibrous filter material. An adsorbent filter section can also be provided.

Abstract: A prediction is calculated to determine whether a content item posted on a social networking system infringes on copyrights or otherwise violates the system's terms of use. The predictions are generated using social signals that are based on social information surrounding the content item, such as the density of connections between the posting user and the viewing users, the profile information of the users, and the geographical separation between the users. The content item is disabled if the prediction indicates a violation and the violation can be verified.

Abstract: The present invention relates to plant-produced angiogenins, to related plant cells, plant calli, plants, seeds and other plant parts and products derived therefrom and to uses of plant-produced angiogenins. The present invention also relates to expression of angiogenin genes in plants and to related nucleic acids, constructs and methods.

Abstract: A utility belt, especially for use by medical personnel, has a first strip of material adapted to encircle the waist of a person wearing the belt, and a second strip attached to an outer face of the first strip. The second strip has one or more partial loops formed therein, defining attaching points for connection of one or more items to the belt. At least one of the items is connected to the belt by an extensible device that permits the item to be pulled away from the belt and used without disconnecting it from the belt. The belt is made of a material that can be washed and sterilized.
