The numerical range of a product
Journal of Mathematical Analysis and Applications, 1970 in terms of W(A) and W(B). In [l] we obtained results on this problem by restricting B to be nonnegative. Here and throughout A and B are “operators”, which means that they are bounded linear operators on the complex Hilbert space H. For any collection of sets (8, : 01 E A}, by cl.

Linear Algebra and its Applications, 2015 Abstract Relying on the ideas of Stampfli [14] and Magajna [12] we introduce, for operators S and T on a separable complex Hilbert space, a new notion called the numerical range of S relative to T at r ∈ σ ( | T | ) . Some properties of these numerical ranges are proved.

FEBS Letters, EarlyView.α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

Numerical Range on Weighted Hardy Spaces as Semi Inner Product Spaces
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 The semi-inner product, in the sense of Lumer, on weighted Hardy space which generate the norm is unique. Also we will discuss some properties of the numerical range of bounded linear operators on weighted Hardy spaces.

Journal of Advances in Modeling Earth Systems, 2020 The parametrization of orographic drag processes is a major source of circulation uncertainty in models. The COnstraining ORographic Drag Effects (COORDE) project makes a coordinated effort to narrow this uncertainty by bringing together the modeling ...

The numerical range of a class of periodic tridiagonal operators [PDF]
Linear and multilinear algebra (2020), 2019 In this paper we compute the closure of the numerical range of certain periodic tridiagonal operators. This is achieved by showing that the closure of the numerical range of such operators can be expressed as the closure of the convex hull of the uncountable union of numerical ranges of certain symbol matrices.

Large scale numerical simulations of "ultrametric" long-range depinning
, 2004 The depinning of an elastic line interacting with a quenched disorder is studied for long range interactions, applicable to crack propagation or wetting.

FEBS Letters, EarlyView.Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Numerical Range and the Dynamics of a Rational Function
, 2010 Sometimes we obtain attractive results when associating facts to simple elements. The goal of this work is to introduce a possible alternative in the study of the dynamics of rational ...
