Modeling 5G-NR-Based Positioning Accuracy in Urban Environments
IEEE AccessModeling phenomena influencing radiocommunication networks, such as 5G-NR, is a key aspect during their development and further optimization. In this paper, one proposes a model, for three different scenario types in urban environments, for user ...

Antimultipath communication by injecting tone into null in signal spectrum [PDF]
, 1987 A transmitter for digital radio communication creates a null by balanced encoding of data modulated on an RF carrier, and inserts a calibration tone within the null. This is accomplished by having the calibration tone coincide in phase and frequency with

Advanced Functional Materials, EarlyView.A novel, high tensile modulus, fully aromatic thermotropic liquid crystalline polyimide (LCPI) with better solvent resistance and thermal stability is synthesized. Tensile specimens are fabricated using both injection molding and FFF processes, accomplished via lower viscosity enabled by the LC phase.

Radio Properties of Low Redshift Broad Line Active Galactic Nuclei Including Extended Radio Sources
, 2010 We present a study of the extended radio emission in a sample of 8434 low redshift (z < 0.35) broad line active galactic nuclei (AGN) from the Sloan Digital Sky Survey (SDSS).

, 2020 This contribution reflects on the state of the art of the digitisation processes of radio archives, looking at the various forms of digitisation of radio archives existing in Europe. We analyse the Dutch, Spanish and British models, the cases of informal archives and finally we pay particular attention to the Italian case, where in 2010 Rai inaugurated

Advanced Functional Materials, EarlyView.In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Advanced Functional Materials, EarlyView.This work investigates modifying interfacial contacts in realizing giant‐performance semiconductor nanomembrane optoelectronics. Strategies, including surface reaction and buffer layer work‐function modulation, are explored to boost the Schottky barrier. An emerging material of YbOx is utilized for near‐ideal Ohmic contact.
