    The Effect of Personalized Virtual Model and Voice Chat Support on Presence in Collaborative Online Shopping

    Collaborative online shopping refers to the activity in which a consumer shops at an online store concurrently with one or more remotely located shopping partners such as her friends or family. Although collaborative shopping is one of the popular ways of shopping in an offline context, many existing studies regarding online shopping have focused mainly on shopping by individuals; few studies have examined how to enhance the collaborative online shopping experience. This study examines two features that have the potential to enhance collaborative online shopping experiences in the context of a clothing store: a personalized virtual model and voice chat support between shopping partners. Drawing from theories of media richness and social presence, we will examine whether implementing these two features can increase telepresence and copresence

    Color Intensity Method for Hydrogel Oxygen Sensor Array

    The oxygen imaging technique to obtain a 2-D distribution is a convenient method because it does not require individual addressing of each sensing element in a sensor array. Until recently, color charge coupled devices (CCDs) have rarely been used for oxygen imaging in spite of usefulness for analyzing the spectral content of images. in this work, a color CCD camera was used for luminescence intensity imaging. Two methods of color intensity analysis are investigated and compared. the first method is to analyze the total Red-Green-Blue (RGB) color intensity of the original color image. the second method involves extracting the red color element to enhance the sensitivity of oxygen measurement. Both commercial Redeye oxygen sensor patches and lab-made photopatterned hydrogel (polyethylene glycol) sensor arrays were used to verify these methods. the linearity and sensitivity of oxygen detection based on the red intensity analysis was improved to those of spectrometric measurement and total color intensity analysis. This method also has potential applications in lifetime imaging, multi-analyte detection, and simultaneous structural and functional imaging of biological systems. © 2006 IEEE

    The Impact of Distance on the Accuracy of Luminance Measurement

    AbstractMany researchers want to reduce the severe luminance difference caused by artificial lights or natural lighting and when luminance is highly uniform. This paper focused on the correlation between measured luminance and the distance of measurement from the light source. For this task, two types of luminance measuring methods were adopted. Namely, High Dynamic Range (HDR) image processing and CS-100 instrument for measuring surface luminance and point luminance respectively. The results indicate that there was a 3% decrease in measured luminance as the distance from the light source was increased by 1m

    LINE FUSION GENES: a database of LINE expression in human genes

    BACKGROUND: Long Interspersed Nuclear Elements (LINEs) are the most abundant retrotransposons in humans. About 79% of human genes are estimated to contain at least one segment of LINE per transcription unit. Recent studies have shown that LINE elements can affect protein sequences, splicing patterns and expression of human genes. DESCRIPTION: We have developed a database, LINE FUSION GENES, for elucidating LINE expression throughout the human gene database. We searched the 28,171 genes listed in the NCBI database for LINE elements and analyzed their structures and expression patterns. The results show that the mRNA sequences of 1,329 genes were affected by LINE expression. The LINE expression types were classified on the basis of LINEs in the 5' UTR, exon or 3' UTR sequences of the mRNAs. Our database provides further information, such as the tissue distribution and chromosomal location of the genes, and the domain structure that is changed by LINE integration. We have linked all the accession numbers to the NCBI data bank to provide mRNA sequences for subsequent users. CONCLUSION: We believe that our work will interest genome scientists and might help them to gain insight into the implications of LINE expression for human evolution and disease. AVAILABILITY
