A strong negative association between schizophrenia and rheumatoid arthritis (RA), implying low comorbidity, has been found in 12 of 14 previous studies, which we review. To this literature we add two recently acquired data sets encompassing 28,953 schizophrenia patients, only 31 of whom had comorbid RA. Integrating our new data into those of the previous nine studies, which stratified their po...

Based on a detailed experimental investigation in an aspect-ratio-4 rectangular cell in the range 3.7 x 10(7)<or=Ra<or=3.7 x 10(9), we present evidence of possible scenarios of the long-term dynamics of large-scale circulations (LSC) in bounded large-aspect-ratio turbulent Rayleigh-Bénard convection. Karhunen-Loève analysis of instantaneous velocity fields from long-time particle image velocime...
