On Telecommunication Service Imbalance and Infrastructure Resource Deployment [PDF]
arXiv, 2021 The digital divide restricting the access of people living in developing areas to the benefits of modern information and communications technologies has become a major challenge and research focus. To well understand and finally bridge the digital divide, we first need to discover a proper measure to characterize and quantify the telecommunication ...

Advanced Functional Materials, EarlyView.A laser‐driven strategy enables precise microstructural modulation of Mo₂C, achieving nanoscale grain control (15.6 ± 5 nm) and an ultrahigh grain boundary density (130 µm−1). Moreover, high‐angle grain boundaries enhance active sites, facilitate electron transport, and optimize hydrogen adsorption kinetics, significantly reducing overpotential.

European Telecommunication Regulation - Effects on Telecommunication Providers [PDF]
SSRN Electronic Journal, 2010 This paper considers the impact of European telecom regulation on the value of affected companies. Employing a repeating AR-GARCH model, I compare the effect of three types of regulation which are categorized based on the addressed subject, i.e. cross-market, country-specific and company-specific regulation.
