Publication number: 20130190206Abstract: The present invention describes a spatial addressing technique that uses a very high-density micro-pore array for high-throughput screening of biological interactions. The therapeutic, diagnostic and drug-discovery implications of being able to identify, select and characterize specific protein-protein, protein-DNA and/or protein-carbohydrate interactions from heterogeneous populations of millions (to billions) of cells is discussed. Importantly, this technique possesses the screening and selection capacity of current display-based screening systems (i.e., millions-billions) but with greater efficiency and shorter time.Type: ApplicationFiled: July 13, 2011Publication date: July 25, 2013Applicant: Dublin City UniversityInventors: Paul Leonard, Ivan Dimov, Richard O'Kennedy, Valerie Fitzgerald

Publication number: 20130101290Abstract: In wavelength switching optical networks, the optical data being transmitted may be routed to different end points by switching the operating frequency of the laser. However, the phase noise of the laser source increases following a switching event. This increased phase noise can prevent the successful transmission of phase modulation formats which are sensitive to it. Accordingly, it is generally necessary to wait a short period before transmitting data. However, the period may be as long as the data packet being transmitted (e.g. 3 ?S), which is a limiting factor. The present application obviates this problem by including a radio frequency pilot tone with the data prior to modulation onto the optical carrier.Type: ApplicationFiled: April 12, 2011Publication date: April 25, 2013Applicant: DUBLIN CITY UNIVERSITYInventors: Prince Anandarajah, Liam Barry, Philip Perry, Kai Shi, Frank Smyth

Patent number: 8285996Abstract: A database management system (1) comprises up to fifty or more workstations (2), each for a user. The environment may, for example, be a hospital and the system manages medical records in a secure manner. Each user has a private key issued by a KGC (5). A database controller (3) updates a secure database (3) with data and associated signatures generated by the user workstations (2). Thus every record of the secure database (3) has a signature to provide full traceability and non-repudiation of data edits/updates. It is important for the system (1) that the signatures are verified on a regular basis, say every hour. Such a task would be extremely processor-intensive if the database (3) is large. However this is performed by a verification processor (4) of the system (1) in a much shorter time than heretofore, t1+n(&Dgr;), where t1 is the time for one verification, n is the number of signatures, and &Dgr; is a time value which is a very small proportion of t1 (less than 1%).Type: GrantFiled: September 28, 2006Date of Patent: October 9, 2012Assignee: Dublin City UniversityInventors: Noel McCullagh, Michael Scott, Neil Costigan

Judicious selection of a precursor compound used within the gas plasma reactor can provide for generation of a layer on the individual surfaces. Desirably the surface or barrier layer is generated through the chemical adsorption of a metalloid oxide such as a silicon oxide layer on the surface of the individual channels or cavities.Type: ApplicationFiled: June 18, 2010Publication date: August 30, 2012Applicant: Dublin City UniversityInventors: Ram Prasad Gandhiraman, Lourdes Basabe-Desmonts, Asif Riaz, Luke Lee, Ivan Dimov, Jens Ducree, Stephen Michael Daniels
