Polar codes are the first capacity achieving and efficiently implementable codes for classical communication. Recently they have also been generalized to communication over classical-quantum and quantum channels. In this work we present our recent results for polar coding in quantum information theory, including applications to classical-quantum multiple access channels, interference channels a...

The use of distinct, dedicated communication channels to transmit data and control traffic introduces a single point of failure for a denial of service attack, in that an adversary may be able to jam control channel traffic and prevent relevant data traffic. Hence, it is of interest to design control channel access schemes which are resilient to jamming. We map the problem of providing resilien...

The current trend in technological evolution is leading telecommunications to all-IP network scenarios, where multiple services are transported as IP packets. Among these are the services based in group communications over IP with confidentiality requirements. Secure IP multicast may be used for the secure broadcasting of multiple video channels over IP. However, scenarios where users switch ra...

Molecular communication is a novel paradigm that uses molecules as an information carrier to enable nanomachines to communicate with each other. Interconnections of the nanomachines with molecular communication is envisioned as a nanonetwork. Nanonetworks are expected to enable nanomechines to cooperatively share information such as odor, flavour, light, or any chemical state. In this paper, we...

objective: parents are believed to be among the most influential adults who have a deterministic role in the success of interventional programs on adolescents' reproductive health. the aim of this study is to describe parents' perceptions and attitudes towards adolescent reproductive needs, experiences and associated factors. method: a population-based study of 539 parents of adolescent boys, a...
