According to Huntington (1933: 278), the term "Boolean algebra" was introduced by Henry M. Sheffer (1882 1964) in the paper where he showed that one could give a five-equation axiomatization of Boolean algebra using the single fundamental operation of joint exclusion, now known as the Sheffer stroke (see Sheffer 1913).
While this was done to reduce the possibility of reverse causation (as described above), the original participation bias, together with the selection bias of women without joint pain or stiffness and exclusion of women with missing physical activity data, meant that our samples were more physically active than the general population of mid-age women and older women.
Further exclusion of hip joints in which the acetabular rims could not be identified (n = 7) or in which the center-edge angle of Wiberg (1939) was ≥ 25° (n = 14) defined the final study group of 95 hip joints in 54 pelvises/patients (13 unilateral DDH and 41 bilateral DDH).
12 Cases were recruited from NOAR, a primary care-based cohort of subjects with new onset IP. 13 In brief, NOAR aims to recruit all new adult attendees at primary care with IP, defined as swelling of two or more joints, lasting >4 weeks, after exclusion of diagnoses other than undifferentiated IP, post-viral IP, RA or psoriatic arthritis.
For the subsample of psychotherapy patients, the joint analysis of exclusion criteria showed no associations with the exclusion criterion 'not meeting minimum severity threshold'.
The reduction of clinical disease activity below a disease activity score of 2.6 when evaluating the 28 relevant joints (DAS28), as well as the exclusion of still remaining clinically silent synovial inflammation, are considered to be the principal goals of current rheumatologic treatment concepts [ 1].
With a married couple, Mr. Miller said, if the property is in one spouse's name, but the couple file a joint income tax return, the couple are entitled to an exclusion of up to $500,000.
At once Mary rejected proposals, advanced particularly by the earl of Danby, that she become sole ruler to the exclusion of her husband, and on April 11 , 1689 she and William were crowned joint sovereigns of England, Scotland, and Ireland.
Joint analyses of the combined pedigree provided (1) greater significance of shared QTL, (2) exclusion of false suggestive QTL and (3) greater mapping precision for shared QTL.
