On the C*-envelope of approximately finite-dimensional operator algebras [PDF]

open access: yesarXiv, 1995
The C*-envelope of the limit algebra (or limit space) of a contractive regular system of digraph algebras (or digraph spaces) is shown to be an approximately finite C*-algebra and the direct system for the C*-envelope is determined explicitly.

External validation of current quality care metrics after radical nephroureterectomy

open access: yesBJU International, EarlyView.
Objectives To externally validate the tetrafecta and pentafecta frameworks for assessing the quality of radical nephroureterectomy (RNU) and their correlation with oncological outcomes in patients with localised upper tract urothelial carcinoma (UTUC).

On the Realization of quantum gates coming from the Tracy-Singh product [PDF]

open access: yesarXiv
The Tracy-Singh product of matrices permits to construct a new gate $c \boxtimes c'$ from two $2$-qudit gates $c$ and $c'$. If $c$ and $c'$ are both Yang-Baxter gates, then $c \boxtimes c'$ is also a Yang-Baxter gate, and if at least one of them is entangling, then $c \boxtimes c'$ is also entangling.

Cuntz-Pimsner C*-algebras and crossed products by Hilbert C*-bimodules [PDF]

open access: yesarXiv, 2005
Given a correspondence X over a C*-algebra A, we construct a C*-algebra and a Hilbert C*-bimodule over it whose crossed product is isomorphic to the augmented Cuntz-Pimsner C*-algebra of X. This construction enables us to establish a condition for two augmented Cuntz-Pimsner C*-algebras to be Morita equivalent.

COMBINATION CHEMOTHERAPY OF MITOMYCIN C AND CYTOSINE ARABINOSIDE IN THE INTRAVESICAL ROUTE FOR BLADDER TUMORS [PDF]

open access: yes, 1978
Intravesical combination chemotherapy was performed in 48 cases with bladder tumors. Mitomycin C 10 mg was administered concomitantly with cytosine arabinoside 20 mg (4 cases, group A), 100 mg (21 cases, group B), 200 mg (3 cases, group C) or 300 mg (20 ...

Hypertranscription of rDNA Responsible for Nucleolar Remodelling is a Doorman for Acquiring Pluripotency

open access: yesCell Proliferation, EarlyView.
Active nucleoli have the capability to release perinuclear heterochromatin, which is a novel event of iPSC reprogramming. ABSTRACT Ribosome biogenesis occurs within the nucleolus, with the initial step being the transcription of ribosomal DNA (rDNA). Although rDNA transcription is limited in somatic cells, it is more active in stem cells. Nevertheless,

C*-dynamical systems associated to Graph C*-Algebras [PDF]

open access: yesarXiv, 2011
We use a characterization of the graph C*-algebras C*(E) as the Stacey crossed product C*(E)^\gamma \times_{\beta_E} N, to study its ideal properties in terms of the (non-classical) C*-dynamical system (C*(E)^\gamma, \beta_E)

A model for the differentiation of human natural killer cells. Studies on the in vitro activation of Leu-11+ granular lymphocytes with a natural killer-sensitive tumor cell, K562. [PDF]

open access: yes, 1985
A subpopulation of low density granular lymphocytes that express the natural killer (NK) cell-associated Leu-11 antigen (IgG Fc receptor) were stimulated directly by coculture with an NK-sensitive tumor cell, K562.
