let $mathcal m$ be a factor von neumann algebra. it is shown that every nonlinear $*$-lie higher derivation$d={phi_{n}}_{ninmathbb{n}}$ on $mathcal m$ is additive. in particular, if $mathcal m$ is infinite type $i$factor, a concrete characterization of $d$ is given.

Zeitgenössische IT-Sicherheit operiert in einer Überbietungslogik zwischen Sicherheitsvorkehrungen und Angriffsszenarien. Diese paranoid strukturierte Form negativer Sicherheit lässt sich vom Ursprung der modernen Kryptografie über Computerviren -würmer, Ransomware Backdoors bis hin zum AIDS-Diskurs 1980er Jahre nachzeichnen. Doch mit digital vernetzten Medien auch anders denken: Marie-Luise Sh...

Research Highlights Dissecting the mechanism of trypanothione synthetase under in vivo-like conditions All proteins of the trypanothione metabolism are indispensable for the viability of African trypanosomes. A final conclusion as to which protein plays a main role in the pathway control yet would need a reliable model based on the kinetic parameters of all enzymes obtained under conditions tha...

background von hippel-lindau (vhl) disease is a hereditary, autosomal dominant syndrome which is manifested by a range of different benign and malignant tumors. this disease can present with different clinical presentations such as; retinal angioma (ra), hemangioblastoma (hb) of the central nervous system (cns), pheochromocytoma (pheo), and epididymal cystadenoma. tumors are usually accompanied...

we report an unusual case of a young male with cerebellar hemangioblastoma treated previously for medullary carcinoma of thyroid, whose pet/ct scans revealed a constellation of findings that suggested the rare von hippel lindau syndrome. the diagnosis was clinched by confirming the findings on whole body contrast enhanced computed tomography (cect) and contrast enhanced magnetic resonance imagi...

By the Von Neumann regular graph of R, we mean the graph that its vertices are all elements of R such that there is an edge between vertices x,y if and only if x+y is a von Neumann regular element of R, denoted by G_Vnr (R). For a commutative ring R with unity, x in R is called Von Neumann regular if there exists x in R such that a=a2 x. We denote the set of Von Neumann regular elements by V nr...
