A Universal Toughening and Energy‐Dissipating Strategy for Impact‐Resistant 3D‐Printed Composites

Advanced Science, EarlyView.
A universal toughening and energy dissipation strategy inspired by B─O bonds, which can significantly enhance the mechanical properties of composites, enables 3D‐printed smart impact‐resistant structures. Abstract 3D‐printed polymer‐based composites are promising for various engineering applications due to high strength‐to‐weight ratios and design ...

“Going out to get in”—Roles of forest conflicts in bottom‐linked environmental governance progressing toward socio‐political innovations

Environmental Policy and Governance, Volume 32, Issue 6, Page 478-491, December 2022., 2022
Abstract Social innovation literature focuses commonly on roles of cooperation in addressing co‐evolution of civil society initiatives and state‐based governance toward sustainable solutions. However, roles of conflicts in driving social change are scarcely addressed in social innovation literature.

A Multi-Domain Anti-Jamming Defense Scheme in Heterogeneous Wireless Networks

IEEE Access, 2018
In this paper, we investigate the anti-jamming problem in heterogeneous wireless networks. Although there are many studies on the anti-jamming defense problem in both power domain and spectrum domain, these two important aspects were addressed separately.

Waveform and Filter Design for Integrated Sensing and Communication Against Signal-dependent Modulated Jamming [PDF]

This paper focuses on an integrated sensing and communication (ISAC) system in the presence of signal-dependent modulated jamming (SDMJ). Our goal is to suppress jamming while carrying out simultaneous communications and sensing.

Polarization‐Controlled Transmissive Plasmonic Color Filter Using a Dimer‐Aperture Array

Advanced Science, EarlyView.
An aluminum dimer aperture array plasmonic metasurface is proposed and fabricated to achieve efficient polarization‐color filtering with CMOS‐compatible materials. The structure's simultaneous polarization‐color filtering capability is shown using structural color generation, where color gamut coverage of 76% and extinction ratio over 20 is achieved ...

Defeating Proactive Jammers Using Deep Reinforcement Learning for Resource-Constrained IoT Networks

, 2023
Traditional anti-jamming techniques like spread spectrum, adaptive power/rate control, and cognitive radio, have demonstrated effectiveness in mitigating jamming attacks. However, their robustness against the growing complexity of internet-of-thing (IoT)

Anion Localization on Termini of a Non‐Fullerene Acceptor Aids Charge Transport

Advanced Energy Materials, EarlyView.
Time‐resolved infrared spectroscopy, in conjunction with computational chemistry, transient absorption spectroscopy, and morphology characterization, is employed to demonstrate spatial localization of the radical anion on the terminal units of non‐fullerene acceptors.

‘It makes you not want to eat’: Perceptions of anti‐obesity public health campaigns in individuals diagnosed with an eating disorder

European Eating Disorders Review, Volume 31, Issue 1, Page 166-177, January 2023., 2023
Abstract Objective Recent research has highlighted the potentially deleterious effects of anti‐obesity public health campaigns on vulnerable audiences such as those at risk of, or diagnosed with, eating disorders (ED). The qualitative experiences of campaigns in this population group have been little explored.

Repeater jamming suppression method for pulse Doppler fuze based on identity recognition and chaotic encryption

Defence Technology, 2021
Pulse Doppler (PD) fuze is widely used in current battlefield. However, with the threat of repeater jamming, especially digital radio frequency memory technology, the deficiency in the anti-repeater jamming of a traditional PD fuze increasingly emerges ...

Interference-Aware Cooperative Anti-Jamming Distributed Channel Selection in UAV Communication Networks

Applied Sciences, 2018
This paper investigates the cooperative anti-jamming distributed channel selection problem in UAV communication networks. Considering the existence of malicious jamming and co-channel interference, we design an interference-aware cooperative anti-jamming
