A complete characterization of locally primitive normal Cayley graphs of metacyclic groups is given. Namely, let Γ = Cay(G,S) be such a graph, where G ∼= Zm.Zn is a metacyclic group and m = p1 1 p r2 2 · · · p rt t such that p1 < p2 < · · · < pt. It is proved that G ∼= D2m is a dihedral group, and val(Γ ) = p is a prime such that p|(p1(p1 − 1), p2 − 1, . . . , pt − 1). Moreover, three types of ...

background: we report the analgesic efficacy of lumbar epidural adenosine injection in reducing the chronic neuropathic pain in a patient with primitive neuroectodermal tumor. report of the case: in this case report a 13-year-old male with primary neuroectodermal tumor (pnet) was administered in epidural space with adenosine to reduce his pain. the patient received 10ml of 0.25% ropivacaine and...

The ring signature is a group signature without a group manager, so that a signer realizes a signature in the name of the group. In some situations it is necessary for a message to be signed by more than one persons. The scheme of the ring signature with divided key is an algorithm which ensures realizing a key signature by a group of k entities from a group of n entities. Because of the way th...

In a secure multicast communication environment, only valid members belong to the multicast group could decrypt the data. In many previous researches, there is one “group key” shared by all group members. However, this incurs the so-called “1 affects n problem,” that is, an action of one member affects the whole group. We believe this is the source of scalability problems. Moreover, from the ad...

In this work we provide a space complexity analysis of the core language of the LogicGuard framework. Our approach is to abstract away from the formula structure of the core language in order to construct invariants for a recursive function. This final recursive function provided an upper bound for the number of instances of the monitor that need to be kept in memory over any duration of time. ...
