We investigate weighted L p (0 < p < .) convergence of Hermite and Hermite– Fejér interpolation polynomials of higher order at the zeros of Freud orthogonal polynomials on the real line. Our results cover as special cases Lagrange, Hermite– Fejér and Krylov–Stayermann interpolation polynomials.
Intravascular superparamagnetic iron oxide nanoparticles (SPION)-enhanced MR transverse relaxation rates (∆R2(⁎) and ∆R2) are widely used to investigate in vivo vascular parameters, such as the cerebral blood volume (CBV), microvascular volume (MVV), and mean vessel size index (mVSI, ∆R2(⁎)/∆R2). Although highly efficient, regional comparison of vascular(More)
H1-antihistamine is generally a well-tolerated and safe drug. However, in resemblance with all other drugs, H1-antihistamines can also prompt adverse drug reactions (ADRs). We recently encountered the very unusual ADR of H1-antihistamine-induced gynecomastia. A 21-year-old man with idiopathic anaphylaxis was treated with ebastine (Ebastel), a(More)
BACKGROUND Although patients with Klinefelter syndrome have elevated risk and incidence rates for several solid cancers, reports on the incidence of hematological malignancies have been equivocal. CASE REPORT We report a patient diagnosed with angioimmunoblastic T-cell lymphoma in whom Klinefelter syndrome was newly detected. Moreover, we discuss the(More)
Let w λ (x) := (1−x 2) λ−1/2 and P (λ) n be the ultraspherical polyno-mials with respect to w λ (x). Then we denote by E (λ) n+1 the Stieltjes polynomials with respect to w λ (x) satisfying 1 −1 w λ (x)P (λ) n (x)E (λ) n+1 (x)x m dx = 0, 0 ≤ m < n + 1, = 0, m = n + 1. In this paper, we show uniform convergence of the Hermite–Fejér interpolation polynomials(More)
