Simultaneous Wireless Power Transfer and Secure Multicasting in Cooperative Decode-and-Forward Relay Networks

open access: yesSensors, 2017
In this paper, we investigate simultaneous wireless power transfer and secure multicasting via cooperative decode-and-forward (DF) relays in the presence of multiple energy receivers and eavesdroppers.

Study of Gaussian Relay Channels with Correlated Noises

open access: yes, 2010
In this paper, we consider full-duplex and half-duplex Gaussian relay channels where the noises at the relay and destination are arbitrarily correlated. We first derive the capacity upper bound and the achievable rates with three existing schemes: Decode-

Neuroglial Response to High‐Amplitude, Short‐Duration Pressure Transients in Monoculture

open access: yesCell Biochemistry and Function, Volume 44, Issue 5, May 2026.
ABSTRACT Blast‐induced traumatic brain injury (bTBI) was reported in 125,000 U.S. service men and women from 2000 to 2018. With no prophylactic treatments having been granted FDA approval, there is a clear need for further understanding of the impact of blasts on the central nervous system.

Outage Probability of Dual-Hop Multiple Antenna Relay Systems with Interference at the Relay and Destination

open access: yesInternational Journal of Antennas and Propagation, 2014
This paper analyzes the outage performance of a dual-hop relaying system in which the relay is equipped with multiple antennas, while the source and destination have a single antenna.

Outage Analysis of Multi-Relay Networks With Hardware Impairments Using SECps Scheduling Scheme in Shadowed-Rician Channel

open access: yesIEEE Access, 2017
In this paper, we investigate the effect of hardware impairments on the performance of dual-hop amplify-and-forward (AF)/decode-and-forward (DF) multiple relaying networks using switch-and-examine combining with post-selection (SECps) scheduling scheme ...

Double‐Edged Sword of Social Media Algorithms: Assessing the Risks to University Cybersecurity and Student Data Privacy

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
Social media algorithms drive a hidden risk chain: over‐disclosure → behavioral fusion → targeted attacks. We propose a 128‐dim, law‐aware risk scoring model with Drools‐based dynamic alerts for universities. ABSTRACT As universities undergo accelerated digital transformation, social media algorithms—while streamlining campus services—have emerged as a

Differential modulation for two-way wireless communications: a perspective of differential network coding at the physical layer [PDF]

open access: yes, 2009
This work considers two-way relay channels (TWRC), where two terminals transmit simultaneously to each other with the help of a relay node. For single antenna systems, we propose several new transmission schemes for both amplify-and-forward (AF) protocol

Are Workplace Friendships Nothing for Older Workers? Decoding the Psychological Mechanisms Linking Age to Workplace Friendship

open access: yesJournal of Organizational Behavior, Volume 47, Issue 4, Page 665-684, May 2026.
ABSTRACT Given the benefits of workplace friendship, understanding its maintenance is essential. Age is particularly relevant due to the aging and increasingly age‐diverse workforce, yet its relationship with workplace friendship remains unclear, with prior studies reporting positive, negative, or null correlations. As age itself is a proxy for further

Non‐Symbolic Magnitude Processing Is a Strong Correlate of Symbolic Math Skills in Children From Ghana and Côte d'Ivoire

open access: yesDevelopmental Science, Volume 29, Issue 3, May 2026.
ABSTRACT The ability to understand and compare non‐symbolic (e.g., dot arrays) and symbolic (e.g., Arabic numerals) magnitudes is a critical foundation for learning math. A meta‐analysis has revealed that symbolic magnitude processing is a stronger predictor of math performance than non‐symbolic, but the evidence base is restricted almost entirely to ...
