Permutations are a core component of almost every cipher. No matter if we consider the DES [5], AES [2] or most of the other encryption algorithms [6] relevant nowadays, we always find permutation operators as essential building blocks inside. In this contribution we will introduce key-dependent permutation operators of provably excellent quality inspired by chaotic Kolmogorov flows [1, 4]. Fro...

In the first group of developments, we reference the introduction of morphological, functional, and molecular imaging in all the steps of oncology workflow, from treatment planning to treatment delivery phases. Treatment plans based on multimodality images and daily imageguided radiotherapy (IGRT), based on volumetric images, are both becoming routine. Advanced examples of this trend are combin...

Infectious conjunctivitis is a very common presentation to medical professional and ophthalmologist all over the world. Although its typically self-limiting and treatable in almost all of the cases, but we need to be aware of the rare and potentially life threatening if the cause is not promptly identified and treated accordingly. In our case report, we highlighted the rare case of Neisseria me...

The independent domination number of a graph G, denoted i(G), is the minimum cardinality of a maximal independent set of G. A maximal independent set of cardinality i(G) in G we call an i(G)-set. The graph G is called i-excellent if every vertex of G belongs to some i(G)-set. We provide a constructive characterization of i-excellent trees. c © 2002 Elsevier Science B.V. All rights reserved.

Emerging infectious diseases pose an important challenge to public health globally. The identification of an etiologic pathogen responsible for an emerging infection in humans can be a major task. The time required to isolate and characterize a new infectious agent sufficiently to adopt control measures and, when possible, to select and make available curative and preventive treatments can be c...
