A,(T) = [L9(T) ® LQ(T)]IK where K is the kernel of the convolution operator c:Lp(S>LQ(T)->C0(T) by (f®g)(y)(f* g)(y)-4*(r) is the /?-Fourier algebra which was introduced by Figa-Talamanca in [6] where it was shown that ^ ( T ) * isisometrically isomorphic to MP(T), the bounded, translation invariant, linear operators on LP(T), Herz [11] showed that AP(V) is a Banach algebra under pointwise mult...

For the characterization of multipliers Lp(Rd) or more generally, Lp(G) for some locally compact Abelian group G, so-called Figa-Talamanca–Herz algebra Ap(G) plays an important role. Following Larsen’s book, we describe as bounded linear operators that commute with translations. The main result this paper is Ap(G). In fact, demonstrate it coincides space Lp(G),?·?p. Given a multiplier T (Ap(G),...

In the last decade, considerable attention has been paid by graph theorists to the study of spectra of graphs and their interaction with structure and characteristic properties of graphs. After the 'classical' book by N. L. Biggs [12] on algebraic graph theory in general, the first comprehensive monograph on this particular topic, by D. M. Cvetkovic, M. Doob and H. Sachs [34], appeared in 1979....

Endocardial right ventricular (EnRV) leads are described as potential cause of native tricuspid valve regurgitation (TR). Need for cardiac pacing by EnRV or epicardial (EpiRV) lead after repair (TVr) bioprosthetic replacement (bTVR) is common, but little known about their effects post-operatively. Assess clinical outcomes, such TR, function, and risk infection in patients with TV prosthesis fol...

The Advanced SCATterometer (ASCAT) is a real aperture, vertical polarisation, C-band radar designed primarily to provide global ocean winds operationally [Figa-Saldaña et al 2002, Klaes et al 2007]. The main application of these data is the assimilation into numerical weather prediction models, but its dense coverage makes the data also extremely useful for direct use by operational weather for...

A decade has passed since the Hong Kong Observatory (HKO) and Government Flying Service (GFS) jointly commenced operational tropical cyclone (TC) reconnaissance over South China Sea in 2011, currently only such programme region a first USA terminated aircraft western North Pacific 1987. This paper reviews HKO–GFS flights between 2011 2020, including 24 storm-penetrating down to 2000ft 28 dropso...
