1561por Kumar, Mohit, Mukherjee, Priya, Verma, Sahil, Kavita, Shafi, Jana, Wozniak, Marcin, Ijaz, Muhammad Fazal“…Moreover, the designed sanitization procedure performs the optimal key generation by a new Grasshopper–Black Hole Optimization (G–BHO) algorithm. A multi-objective function involving the parameters like degree of modification, hiding rate, correlation coefficient between the actual data and restored data, and information preservation rate was derived and utilized for generating optimal key. …”

1562por Saul, Alice M, Taylor, Bruce V, Blizzard, Leigh, Simpson-Yap, Steve, Oddy, Wendy H, Shivappa, Nittin, Hébert, James R, Black, Lucinda J, Ponsonby, Anne-Louise, Broadley, Simon A, Lechner-Scott, Jeanette, van der Mei, Ingrid“…At baseline, 5- and 10-year reviews, DII and energy-adjusted DII (E-DII(TM)) scores were calculated (food frequency questionnaire) and assessed as predictors of relapses, annualised change in disability (Expanded Disability Status Scale) and two magnetic resonance imaging measures; fluid-attenuated inversion recovery (FLAIR) lesion volume and black hole lesion volume. RESULTS: A more pro-inflammatory diet was associated with a higher relapse risk (highest vs. lowest E-DII quartile: hazard ratio = 2.24, 95% confidence interval (CI) = −1.16, 4.33, p = 0.02). …”
