This minitrack addresses Computer Supported Collaborative Learning Requiring Immersive Presence (CSCLIP). Immersive Presence (IP) may be characterized in at least two ways. First, it allows same-time different-place (STDP) interaction among students, instructors, equipment and Information Technology (IT). Second, it implies a “sense of presence” that is typical in lab or training environments. ...
Traditional musical instruments provide compelling metaphors for human-computer interfacing, both in terms of input (physical, gestural performance activities) and output (sound diffusion). The violin, one of the most refined and expressive of traditional instruments, combines a peculiar physical interface with a rich acoustic diffuser. We have built a new instrument that includes elements of b...
322 subjects participated in an experimental study to investigate the effects of tactile, olfactory, audio and visual sensory cues on a participant's sense of presence in a virtual environment and on their memory for the environment and the objects in that environment. Results strongly indicate that increasing the modalities of sensory input in a virtual environment can increase both the sense ...
We investigate Fano-type anomalous transmission of energy of plane waves across lossless slab scatterers with periodic structure in the presence of non-robust guided modes. Our approach is based on rigorous analytic perturbation of the scattering problem near a guided mode and applies to very general structures, continuous and discrete.
We measure transient strain in ultrafast laser-excited Ge by time-resolved x-ray anomalous transmission. The development of the coherent strain pulse is dominated by rapid ambipolar diffusion. This pulse extends considerably longer than the laser penetration depth because the plasma initially propagates faster than the acoustic modes. X-ray diffraction simulations are in agreement with the obse...
PCR was used to rapidly identify and isolate 1-aminocyclopropane-1-carboxylate (ACC) deaminase genes from bacteria. The Shimodaira-Hasegawa test was used to assess whether phylogenetically anomalous gene placements suggestive of horizontal gene transfer (HGT) were significantly favored over vertical transmission. The best maximum likelihood (ML) ACC deaminase tree was significantly more likely ...
We have observed optical bistability caused by absorption-induced thermal expansion of mirrors forming a Fabry-Perot interferometer. From the resulting anomalous transmission line shapes, absorption coefficients of the mirror coatings as low as 0.2parts in 10(6) (ppm) have been successfully measured.
We present a theoretical and experimental study of the ultranarrow bandwidth Faraday anomalous dispersion optical filter operating at the rubidium D1 line (795 nm). This atomic line gives better performance than other lines for key figures of merit, e.g., simultaneously 71% transmission, 445 MHz bandwidth, and 1.2 GHz equivalent-noise bandwidth.
