ON NUMERICAL RADIUS INEQUALITIES FOR OPERATOR PRODUCTS IN HILBERT SPACES
Проблемы анализаWe establish several numerical radius inequalities for products of two operators on a Hilbert space. Some of the obtained inequalities improve well-known results. More precisely, we show that if 𝐴, 𝐵 \in 𝐵(𝐻) double commute, then 𝑤(𝐴𝐵)

On numerical range of sp(2n, C)
Special Matrices, 2016 In this paper we studied the classical numerical range of matrices in sp(2n, C). We obtained some result on the relationship between the numerical range of a matrix in and that of its diagonal block, the singular values of its off-diagonal block A2.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Numerical range of tensor product of operators in semi-Hilbert spaces
Kuwait Journal of ScienceLet A and B be two positive bounded linear operators acting on the complex Hilbert spaces H and K, respectively. In this paper, we study the (A⊗B)-numerical range WA⊗B(T⊗S) of the tensor product T⊗S for two bounded linear operators T and S on H and K ...

Geometric Characterization of the Numerical Ranges of Generalized Pencils of Pairs of Projections
MathematicsLet H be a complex separable Hilbert space. We study the closure of the numerical range of the generalized pencil T=P+αQ+βPQ, where (P,Q) is a pair of orthogonal projections and (α,β)∈R2.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Norm Properties of $S$-Universal Operators
Communications in Advanced Mathematical Sciences, 2020 We investigate the norm properties of a generalized derivation on a norm ideal $\mathcal{J}$ in $\mathcal{B}(H)$, the algebra of bounded linear operators on a Hilbert space $H$.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
