A game theoretic approach to distributed resource allocation for OFDMA-based relaying networks [PDF]
, 2008 In this paper, algorithms on distributed resource (spectrum and power) sharing for relay stations are investigated for downlink transmissions in an OFDMA-based relay-aided cell. Both system capacity and user fairness are considered. By grouping the relay

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors
Advanced Science, EarlyView.This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

Information reuse in dynamic spectrum access [PDF]
, 2013 Dynamic spectrum access (DSA), where the permission to use slices of radio spectrum is dynamically shifted (in time an in different geographical areas) across various communications services and applications, has been an area of interest from technical ...

Advanced Science, EarlyView.Two‐dimensional CuInP2S6 nanosheets are incorporated into a P(VDF‐TrFE) matrix to induce polarization‐cooperative ferroelectric coupling. The resulting P(VDF‐TrFE)/CuInP2S6 hybrid film exhibits reinforced ferroelectric ordering and reduced coercive electric fields compared with pristine P(VDF‐TrFE).

Benefits of elastic spectrum allocation in optical networks with dynamic traffic
2014 IEEE Latin-America Conference on Communications (LATINCOM), 2014 Traditional optical core networks based on Wavelength Division Multiplexing (WDM) provide optical channels (wavelengths) rigidly allocated over the optical spectrum and separated by 50 or 100 GHz. The novel concept of Elastic Optical Network (EON) can help to improve network flexibility by allocating multiple sub-channels to incoming connection ...

A Generative Neuro‐Symbolic AI for Protein Sequence Design
Advanced Science, EarlyView.We introduce EffieDes, a neuro‐symbolic framework coupling deep learning‐based fitness landscape parameterization with exact automated reasoning. Unlike greedy sampling, EffieDes identifies sequences that globally optimize fitness while satisfying intricate design constraints.

Allocation of Orbit and Spectrum Resources for Regional Communications: What's at Stake? [PDF]
Contentious debate surrounds allocation of the geostationary orbit and electromagnetic spectrum, two resources used by communications satellites. An extensive economics literature alleges that the nonmarket administrative allocative procedures now in ...

Advanced Science, EarlyView.TAB–2TFSI enables efficient ion‐pair doping across a wide range of conjugated polymers, where the strongly oxidizing TAB core drives charge transfer, and the TFSI counterions promote favorable ionic compensation. This dicationic dopant promotes uniform dopant distribution, improves structural order, and increases carrier delocalization, establishing a ...
