Half sphere exposure used in predicting discontinuous B-cell epitopes. Song et al. have developed an online webserver termed HSEpred to predict half-sphere exposure from protein primary sequences. HSEpred server can achieve the correlation coefficients of 0.72 and 0.68 between the predicted and observed HSE-up and HSE-down measures, respectively, when evaluated on a well-prepared non-homologous protein structure dataset. Moreover, residue contact number (CN) can also be accurately predicted by HSEpred webserver using the summation of the predicted HSE-up and HSE-down values, which has further enlarged the application of this new solvent exposure measure. Recently, Heffernan et al. has developed the most accurate predictor for
Science On a Sphere May 4, 2006 the team unveiled "Footprints", the world's first fully realized spherical film. The project demonstrated a number of dramatic new techniques for visual conceptualization, including the idea of a seamless visual wrap. Since the release of "Footprints", several other movies have been made or are currently in production for SOS, including: Today there are over 80 narrated movies for SOS. Science On a Sphere Science On a Sphere (SOS) is a spherical projection system created by NOAA. It presents high-resolution video on a suspended globe rather than a flat screen, with the aim of better representing global phenomena.
