Publication number: 20180122135Abstract: A method and system for synthesising a terrain are provided. The method includes: providing access to multiple exemplar terrain templates and generating a working terrain image with target terrain dimensions and an associated working terrain height image. Generating the working terrain image includes sampling a plurality of the exemplar terrain templates for addition of the templates to the working terrain image, and performing image synthesis to improve the working terrain image including height matching the exemplar terrain samples. The method enables control of modification of the working terrain image by applying user-defined constraints to modify the synthesised terrain. The method outputs the working terrain image as a synthesised terrain in the form of a height-field.Type: ApplicationFiled: April 29, 2016Publication date: May 3, 2018Applicant: University of Cape TownInventors: James Edward GAIN, Bruce Charles MERRY, Patrick Craig MARAIS

Patent number: 9931339Abstract: Compounds, including quinoxaline derivatives of formula I, for use in the treatment of cancer are described. In general, the compounds inhibit the import of proteins and transcription factors such as Kpn?, AP-1, P65, NFAT into the nucleus of a cell by inhibiting the nuclear import protein, Kpn?1. Cancer cells have elevated levels of Kpn?1 and the inhibition of their nuclear import activity induces cell apoptosis. The administration of an effective amount of any one of the compounds results in cell apoptosis in cancer cells, while non-cancer cells are substantially unaffected by the inhibition of Kpn?1's nuclear import activity.Type: GrantFiled: August 7, 2015Date of Patent: April 3, 2018Assignees: University of Cape Town, University of Louisville Research Foundation Inc.Inventors: Virna Drucille Leaner, Pauline Janet Van Der Watt, John Olaf Trent

Patent number: 9518986Abstract: An aptamer-based SERS detection technique that directly monitors an aptamer-analyte capture event by generating spectroscopic information regarding the identity of the analyte that has been bound to the aptamer from a complex biological sample. A reproducible SERS spectrum is measured for an aptamer-analyte complex formed on a metal surface and this spectral information is used directly to identify the specific aptamer-analyte complex and optionally also to quantify the analyte in the sample, thus enabling discrimination between true and false positives in quantitative analyte assays on complex biological samples. In one embodiment the aptamer is attached directly to the metal surface and surrounded by a self-assembled monolayer (SAM) of amphiphilic molecules. In an alternative embodiment the metal surface is coated with a SAM and the aptamer is attached to the amphiphilic molecules of the SAM.Type: GrantFiled: November 2, 2012Date of Patent: December 13, 2016Assignee: University of Cape TownInventors: Jonathan Michael Blackburn, Michael Evans, Sriram Krishnan, Christa Lynn Brosseau
