gCubik: real-time integral image rendering for a cubic 3D display

Abstract: gCubik provides a 3D visual experience, which is interactive and group-shared, by using a graspable cubic display. Users are presented with color, stereo and full motion parallax 3D scenes, viewable from any direction, without the need of special glasses. Newly designed wide field of view integral photography(IP) lens array are employed on each face of the display for its autostereoscopic effect. In our demonstration, real-time rendering of the IP images allows users to interactively manipulate the 3D objects in the scene via simple finger gestures.

Accelerated one-step generation of full-color holographic videos using a color-tunable novel-look-up-table method for holographic three-dimensional television broadcasting.

Abstract: A color-tunable novel-look-up-table (CT-NLUT) for fast one-step calculation of full-color computer-generated holograms is proposed. The proposed method is composed of four principal fringe patterns (PFPs) such as a baseline, a depth-compensating and two color-compensating PFPs. CGH patterns for one color are calculated by combined use of baseline-PFP and depth-compensating-PFP and from them, those for two other colors are generated by being multiplied by the corresponding color-compensating-PFPs. color-compensating-PFPs compensate for differences in the wavelength between two colors based on their unique achromatic thin-lens properties, enabling transformation of one-color CGH pattern into those for other colors. This color-conversion property of the proposed method enables simultaneous generation of full color-CGH patterns, resulting in a significant reduction of the full color-CGH calculation time. Experimental results with test scenario show that the full color-CGH calculation time of the proposed CT-NLUT has been reduced by 45.10%, compared to the conventional NLUT. It has been further reduced by 96.01% when a data compression algorithm, called temporal redundancy-based NLUT, was used together, which means 25-fold reduction of its full color-CGH calculation time. Successful computational and optical reconstructions of full color-CGH patterns confirm the feasibility of the proposed method.

Current management of chronic suppurative otitis media in infants and children.

Abstract: Most children who have chronic suppurative otitis media require: (1) a thorough examination of the external canal and tympanic membrane with the otomicroscope (under general anesthesia, if necessary); (2) a Gram stain and culture obtained directly from the middle ear; (3) thorough aspiration of the ear canal and, if possible, the middle ear, i.e. "aural toilet"; (4) treatment with an orally administered antimicrobial agent and an ototopical medication, if the organisms are susceptible; and if the suppurative process is unresponsive to this management, hospitalization and the parenteral administration of an antimicrobial agent. Parenteral antimicrobial therapy should be selected following microbiologic assessment of the discharge. If the infection can be eliminated using the methods described above, prevention of recurrence can be achieved by the following options: (1) prophylactic antimicrobial therapy; (2) removal of the tympanostomy tube; or (3) surgical repair of the tympanic membrane defect. The choice of these options depends on the age of the child and the status of the function of the eustachian tube. Middle ear and mastoid surgery should be reserved for those children who fail to respond to intensive medical therapy.

Components of a research 2.0 infrastructure

Abstract: In this paper, we investigate the components of a Research 2.0 infrastructure. We propose building blocks and their concrete implementation to leverage Research 2.0 practice and technologies in our field, including a publication feed format for exchanging publication data, a RESTful API to retrieve publication and Web 2.0 data, and a publisher suit for refining and aggregating data. We illustrate the use of this infrastructure with Research 2.0 application examples ranging from a Mash-Up environment, a mobile and multitouch application, thereby demonstrating the strength of this infrastructure.
