Embedding Dimensions of Finite von Neumann Algebras [PDF]

arXiv, 2006
We introduce "embedding dimensions" of a family of generators of a finite von Neumann algebra when the von Neumann algebra can be faithfully embedded into the ultrapower of the hyperfinite II$_1$ factor. These embedding dimensions are von Neumann algebra invariants, i.e., do not depend on the choices of the generators.

The classification problem for von Neumann factors [PDF]

arXiv, 2009
We prove that it is not possible to classify separable von Neumann factors of types $\II_1$, $\II_\infty$ or $\III_\lambda$, $0\leq \lambda\leq1$, up to isomorphism by a Borel measurable assignment of "countable structures" as invariants. In particular the isomorphism relation of type $\II_1$ factors is not smooth.

Postpartum von Willebrand factor levels in women with and without von Willebrand disease and implications for prophylaxis

Haemophilia, 2015
The aim of this study was to elucidate the fall in von Willebrand factor (VWF) and factor VIII activity (FVIII) after childbirth in women with and without von Willebrand disease (VWD).

Patient with von Willebrand Disease for Gynaecologic Surgery - Perianaesthetic Concerns

Indian Journal of Anaesthesia, 2008
We report a case of von Willebrand (vWD) disease and highlight the relevance of this condition to the perianaesthetic management.A 23-year-old female, known case of vWD diagnosed at 3 years of age, was posted for laparoscopic ovarian cystectomy.

Factoriality of q-Gaussian von Neumann algebras [PDF]

arXiv, 2003
We prove that the von Neumann algebras generated by $n$ $q$-Gaussian elements, are factors for $n\ge 2$.

Ibrutinib treatment affects collagen and von Willebrand factor-dependent platelet functions.

Blood, 2014
The oral Bruton's tyrosine kinase inhibitor, ibrutinib, has recently demonstrated high efficiency in patients with relapsed B-cell malignancies. Occurrence of bleeding events has been reported in a subgroup of ibrutinib-treated patients.

von Willebrand factor propeptide: biology and clinical utility.

Blood, 2015
von Willebrand factor (VWF) is a large multimeric glycoprotein that mediates the attachment of platelets to damaged endothelium and also serves as the carrier protein for coagulation factor VIII (FVIII), protecting it from proteolytic degradation ...

The Pan African Medical Journal, 2017
Von Willebrand Disease (VWD) is the most common human inherited bleeding disorder due to a defect of Von Willebrand Factor (VWF), which a glycoprotein crucial for platelet adhesion to the subendothelium after vascular injury.

Approximate double commutants in von Neumann algebras [PDF]

arXiv, 2011
Richard Kadison showed that not every commutative von Neumann subalgebra of a factor von Neumann algebra is equal to its relative double commutant. We prove that every commutative C*-subalgebra of a centrally prime C*-algebra $B$ equals its relative approximate double commutant. If $B$ is a von Neumann algebra, there is a related distance formula.
