For any ϵ > 0 the function ( 1 - | ϵ x | ) + is compactly supported, positive definite and approximates 1 uniformly on compact sets as ϵ → 0. Hence the function f ϵ ( x ) = ( 1 - | ϵ x | ) + f ( x ) is positive definite, approximates f uniformly on R and supp f ϵ ⊆ Ω ¯ ∩ - 1 ϵ, 1 ϵ.
Albumin is also prescribed in certain specific conditions and diseases, such as kernicterus, plasmapheresis, and graft versus host disease [ 2], even though these indications are not supported by definite evidence.
Use of passive immunotherapy was considered; however, no studies support a definite benefit, and no readily available safe source of such products exists.
Lacking any effect on primary endpoint, that is Ki-67 LI reduction, it is difficult to support a definite preventive role of a weekly dose of tamoxifen or raloxifene in premenopause.
Propper's conclusion appears to be supported by the definite positive relationship between the quality of departmental management and success on all three rankings (albeit accompanied by a huge amount of scatter).
Then there exists a compactly supported continuous positive definite function F such that f - F ∞ ≤ ϵ.
All cases had definite, clinically definite, or laboratory-supported definite MS according to the McDonald and Poser criteria, respectively.
All patients included in the study were diagnosed as having either clinically definite MS or laboratory-supported definite MS or definite MS according to standard clinical criteria [28], [29], [30].
Eligible patients had clinically definite or laboratory-supported definite MS by Poser criteria and a primary progressive (PP), secondary progressive (SP), or relapsing/remitting (RR) course.
Patients enrolled in the PRISMS study had a clinically definite or laboratory-supported definite diagnosis of MS of 5.3 (median) years' duration prior to the study start, and patients receiving placebo had this untreated period extended for a further 2 years [22].
Patients enrolled were diagnosed as having clinically definite MS (CDMS) or laboratory-supported definite MS of at least 1 year's duration with an Expanded Disability Status Scale (EDSS) score of ≤ 5.0 and at least two relapses in the proceeding 2 years [22].
