Sum secrecy rate in multicarrier DF relay beamforming

, 2014
In this paper, we study sum secrecy rate in multi-carrier decode-and-forward relay beamforming. We obtain the optimal source power and relay weights on each subcarrier which maximize the sum secrecy rate.

Mobile jammers for secrecy rate maximization in cooperative networks [PDF]

2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
We consider a source (Alice) trying to communicate with a destination (Bob), in a way that an unauthorized node (Eve) cannot infer, based on her observations, the information that is being transmitted. The communication is assisted by multiple multi-antenna cooperating nodes (helpers) who have the ability to move.

Experience With Performing Rheocarna Therapy via the Single‐Needle Method for Treatment of Chronic Limb‐Threatening Ischemia

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction This study investigated the safety and efficacy of single‐needle Rheocarna therapy for chronic limb‐threatening ischemia (CLTI) with wounds. Methods Six patients with CLTI involving ulcers unresponsive to revascularization underwent single‐needle Rheocarna treatment.

Long-Term Secrecy Throughput and Fairness Tradeoff for Wireless Powered Secure IoT Networks

IEEE Open Journal of the Communications Society
This paper focuses on the interplay between secrecy throughput and fairness for a wireless powered secure Internet of Things (IoT) network, where IoT devices harvest energy from an access point (AP), and securely upload their data to the AP by exploiting

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.
