On Relay Assignment in Network-Coded Cooperative Systems
IEEE Transactions on Wireless Communications, 2011 We consider in this paper relay assignment for cooperative systems with multiple two-way relay channels. The nodes corresponding to one two-way relay channel (henceforth referred to as pair) communicate with each other through a relay. The relays use network coding to simultaneously transmit the signals corresponding to the pairs they are assigned to ...

Cooperative Local Caching under Heterogeneous File Preferences
, 2016 Local caching is an effective scheme for leveraging the memory of the mobile terminal (MT) and short range communications to save the bandwidth usage and reduce the download delay in the cellular communication system. Specifically, the MTs first cache in

Advanced Materials, EarlyView.The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures
Advanced Materials, EarlyView.Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks
Advanced Materials, EarlyView.ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

Electronic Structure Modulation Induced by Asymmetric Cu─Ni Centers in a π‐Conjugated Triazine MOF
Advanced Materials Interfaces, EarlyView.A π‐conjugated H3TATB‐based asymmetric bimetallic CuNi‐MOF was developed as an efficient electrocatalyst for alkaline hydrogen evolution. Benefiting from synergistic Cu–Ni interactions, enhanced charge transfer, and stabilized active sites, CuNi‐MOF delivers superior HER performance with low overpotential, improved kinetics, and 24 h durability.
