Distributed Authorization with Distributed Grammars [PDF]
, 2015 While groups are generally helpful for the definition of authorization policies, their use in distributed systems is not straightforward. This paper describes a design for authorization in distributed systems that treats groups as formal languages. The design supports forms of delegation and negative clauses in authorization policies. It also considers

A distributional Hardy transformation
International Journal of Mathematics and Mathematical Sciences, 1979 The Hardy's F-transform F(t)=∫0∞Fv(ty)yf(y)dy is extended to distributions. The corresponding inversion formula f(x)=∫0∞Cv(tx)tF(t)dt is shown to be valid in the weak distributional sense.

Distributed verification and hardness of distributed approximation [PDF]
Proceedings of the forty-third annual ACM symposium on Theory of computing, 2011 We study the {\em verification} problem in distributed networks, stated as follows. Let $H$ be a subgraph of a network $G$ where each vertex of $G$ knows which edges incident on it are in $H$. We would like to verify whether $H$ has some properties, e.g., if it is a tree or if it is connected.

Re-evaluating Phoneme Frequencies
Frontiers in Psychology, 2020 Causal processes can give rise to distinctive distributions in the linguistic variables that they affect. Consequently, a secure understanding of a variable's distribution can hold a key to understanding the forces that have causally shaped it. A storied

Distributed Experiments and Distributed Learning
International Journal of Online and Biomedical Engineering (iJOE), 2020 The paper, an enhanced version of conference key presentation, investigates, how the development of new needs in education and developments in IT triggered technology enhanced learning. Online labs play an important in that area. Federation of labs is the new direction to answer the challenges, which come from the intensive use of online labs in the ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Generalized completely integrable systems [PDF]
Theoretical and Applied MechanicsDynamical systems more general than Hamiltonian systems are considered. The role of the Hamiltonian function is played by a 1-form (not necessarily closed) on a symplectic phase space.
