Abstract: In a ray tracer, to prevent any long-running query from hanging the graphics processing unit, a traversal coprocessor provides a preemption mechanism that will allow rays to stop processing or time out early. The example non-limiting implementations described herein provide such a preemption mechanism, including a forward progress guarantee, and additional programmable timeout options that can be time or cycle based. Those programmable options provide a means for quality of service timing guarantees for applications such as virtual reality (VR) that have strict timing requirements.

Abstract: A method and apparatus are provided for a user to construct a payload comprising content, such as multimedia, or references to content. The payload may be provided with further elements, such as a title or initial comments. The payload may be sent to any immediate contact of the user. Upon receipt by other users, the payload may be forwarded to any of the others' immediate contacts. Additionally, comments can be made by anyone in receipt of the payload for others in receipt of the payload to view. A social networking mechanism is provided, wherein a record is made for each forwarding of a payload and introductions can be made between individuals lying in the same forwarding chain of a payload. Immediate contacts can be collected into groups for ease in addressing. Teams of users can send and forward messages among themselves or to others outside of the team, according to predetermined rules and individuals' standing within the team. Users are provided with a sortable, filterable list of payloads sent to them.

Abstract: The present invention relates generally to the fields of diagnosis and treatment of cancer. More particularly, the present invention provides a method of determining the likely or relative sensitivity of cancer cells to a particular anti-cancer agent prior to or during anti-cancer treatment. Therapeutic protocols for the treatment of cancer based on a determination of the likely or relative sensitivity of the cancer cells to the anti-cancer agent also form part of the present invention. The present invention further contemplates rendering cancer cells sensitive or relatively more sensitive to an anti-cancer agent prior to or during anti-cancer treatment.

Abstract: A chemical agent of the diterpene family obtained from a member of the Euphorbiaceae family of plants for use in the treatment of prophylaxis of prostate cancer or a related cancer or condition.

Abstract: The present invention relates generally to chemical agents useful in the treatment and prophylaxis of inflammatory conditions or in the amelioration of symptoms resulting from or facilitated by an inflammatory condition in a mammalian animal including human and primate, non-mammalian animal and avian species. More particularly, the present invention provides a chemical agent of the macrocyclic diterpene family obtaining from a member of the Euphorbiaceae family of plants or botanical or horticultural relatives thereof or derivatives or chemical analogues or chemically synthetic forms of the agents for use in the treatment or prophylaxis of an inflammatory condition or in the amelioration of symptoms resulting from or facilitated by an inflammatory condition in a mammal, animal or avian species.
