The joint numerical range and the joint essential numerical range
, 2015 Let B(H) denote the algebra of bounded linear operators on a complex Hilbert space H. The (classical) numerical range of T ∈ B(H) is the set W(T) = {〈T x; x〉: x ∈ H; ‖x‖ = 1} Writing T= T_1 + iT_2 for self-adjoint T_1, T_2 ∈ B(H), W(T) can be identified with the set {(〈T_1 x, x〉,〈T_2 x, x〉) : x ∈ H, ‖x‖ = 1}.

FEBS Letters, EarlyView.In the adult T‐cell leukemia/lymphoma (ATL) cell line ED, the human T‐cell leukemia virus type 1 (HTLV‐1) provirus was integrated into the intron of the ift81 gene in the antisense orientation. Despite this integration, both the intact ift81 and the viral oncogene hbz were simultaneously expressed, likely due to the functional insufficiency of viral ...

Numerical ranges of derivations [PDF]
Proceedings of the Edinburgh Mathematical Society, 1978 In this paper we shall examine the relationship between the numerical range of aninner derivation, and that of its implementing element.Much of this paper is taken from the author's doctoral thesis (5) written at theUniversity of Newcastle upon Tyne with the helpful guidance of Professor B. E.Johnson.

Cyclic nucleotide signaling as a drug target in retinitis pigmentosa
FEBS Letters, EarlyView.Disruptions in cGMP and cAMP signaling can contribute to retinal dysfunction and photoreceptor loss in retinitis pigmentosa. This perspective examines the mechanisms and evaluates emerging evidence on targeting these pathways as a potential therapeutic strategy to slow or prevent retinal degeneration.

Numerical ranges and Poncelet curves
Linear Algebra and its Applications, 1998 AbstractConvex circuits which have the property of circles of The Great Poncelet Theorem are introduced. The circuits are generated as boundaries of numerical ranges of specially constructed matrices. Algebraic and geometric properties of such matrices and their numerical ranges are obtained. These properties lead to a new proof of the Poncelet Theorem.

Rewriting the dendritic cell code in cancer—from subset identity to immunotherapeutic design
FEBS Letters, EarlyView.Dendritic cells (DCs) play central roles in cancer immunity but are often subverted by the tumor microenvironment. This review explores the diversity of DC subsets, their functional plasticity, and emerging therapeutic strategies to reprogram DCs for enhanced antitumor responses, including vaccines, in vivo targeting, and DC‐based immunotherapies ...

FEBS Letters, EarlyView.Tuberculosis remains a global health challenge and new therapeutic targets are required. Here, we characterized SseA, a sulfurtransferase from Mycobacterium tuberculosis involved in macrophage infection, and its interaction with the newly identified protein SufEMtb that activates SseA enzymatic activity.
