Secrecy Rate Analysis of UAV-Enabled mmWave Networks Using Matérn Hardcore Point Processes

IEEE Journal on Selected Areas in Communications, 2018
Communications aided by low-altitude unmanned aerial vehicles (UAVs) have emerged as an effective solution to provide large coverage and dynamic capacity for both military and civilian applications, especially in unexpected scenarios. However, because of

Linear Precoding for Broadcast Channels with Confidential Messages under Transmit-Side Channel Correlation

, 2013
In this paper, we analyze the performance of regularized channel inversion (RCI) precoding in multiple-input single-output (MISO) broadcast channels with confidential messages under transmit-side channel correlation.

Enzymatic and microbial routes to bioplastics: The green chemistry frontier of biopolymers

FEBS Open Bio, EarlyView.
Microbial biosynthesis and engineered enzyme platforms are expanding the design space of polyhydroxyalkanoate bioplastics. By combining fermentation, PHA synthase engineering and cell‐free modular systems, tailored biodegradable polymers can be produced with tunable properties, supporting more sustainable materials and future circular bioeconomy ...

Anticipated Suicide Stigma, Secrecy, and Suicidality among Suicide Attempt Survivors.

Suicide and Life-Threatening Behaviour, 2020
OBJECTIVE Suicidal behavior is stigmatized, and suicide attempt survivors often keep their experiences secret. Although secrecy can protect from discrimination, research from related fields suggests that both the experience of stigma and secrecy can ...

Hiding Symbols and Functions: New Metrics and Constructions for Information-Theoretic Security [PDF]

, 2015
We present information-theoretic definitions and results for analyzing symmetric-key encryption schemes beyond the perfect secrecy regime, i.e. when perfect secrecy is not attained. We adopt two lines of analysis, one based on lossless source coding, and

Joint Power Splitting and Secure Beamforming Design in the Wireless-powered Untrusted Relay Networks

, 2015
In this work, we maximize the secrecy rate of the wireless-powered untrusted relay network by jointly designing power splitting (PS) ratio and relay beamforming with the proposed global optimal algorithm (GOA) and local optimal algorithm (LOA). Different

Network Localization of Fatigue in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Fatigue is among the most common symptoms and one of the main factors determining the quality of life in multiple sclerosis (MS). However, the neurobiological mechanisms underlying fatigue are not fully understood. Here we studied lesion locations and their connections in individuals with MS, aiming to identify brain networks ...

Secure Transmission in mmWave Wiretap Channels: On Sector Guard Zone and Blockages

Entropy, 2019
Millimeter-wave (mmWave) communication is one of the key enabling technologies for fifth generation (5G) mobile networks. In this paper, we study the problem of secure communication in a mmWave wiretap network, where directional beamforming and link ...
