Long-term penetration and traffic forecasts for the Western European fixed broadband market [PDF]
The objective with the paper is to describe, analyze and forecast the future fixed broadband penetration and traffic growth in NGN and NGA networks in Western Europe - one of the most advanced telecommunications areas in the world. Analyses show that the

Advanced Science, EarlyView.Based on the anionic Hofmeister effect, a universal strategy of incorporation of stereo‐π anion BPh4− into a series of Cy5 skeletons to unlock long‐lived charge‐separated states was reported, wherein the weak electronic coupling and low charge recombination driving force hinder the charge recombination process, elevating the oxygen‐independent ROS ...

Advanced Science, EarlyView.Hybrid electro‐thermochromic smart windows are developed for dynamic climate control by integrating a redox‐matched black electrochromic gel with a paraffin‐based thermochromic film. This synergistic combination enables multimodal solar modulation, where photothermal heating from the electrochromic layer triggers thermochromic activation at lower ...

Advanced Science, EarlyView.We demonstrate that the inverse relationship between viscosity and conductivity in structured electrolytes can be circumvented by leveraging their hydrogen bonding networks for Grotthuss proton transport. Using a mixture of imidazole and levulinic acid, we show that the existence of extended hydrogen‐bonded chains that can rapidly reorient result in ...

Brain Network Dynamics of Local and Global Predictive Processing in Aging
Advanced Science, EarlyView.Separation of concurrent whole‐brain networks in source‐reconstructed magnetoencephalography (MEG) data suggests that healthy aging reorganizes, rather than uniformly attenuates, neural responses elicited from hierarchical auditory violations. Enhanced early sensory deviance processing alongside reduced higher‐order cognitive responses suggests a large‐

Advanced Science, EarlyView.A rational, solvent‐free synthesis utilizing 2,6‐diaminonaphthalene produces ultrabright green‐emissive carbon dots. Regulated by a self‐limiting oxidative capping mechanism, excitons undergo ultrafast intra‐particle funneling from the nitrogen‐doped carbon core to emissive surface traps.

Enhancing Quasi‐Two‐Dimensional Electronic Structure in Bi2O2Se via Chlorine Substitution
Advanced Science, EarlyView.We demonstrate chlorine substitution as an effective strategy to transform Bi2O2Se into an exfoliatable van der Waals superlattice. Key electronic band feature, including indirect bandgap, effective mass is well preserved, while the 2D character of the system is sufficiently enhanced.
