Directive Antenna Clutter Loss in Slant Paths

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper investigates the development of a clutter loss model specifically for slant paths involving directive antennas. Conventionally, clutter loss is characterized by using isotropic antennas to facilitate standard link budget calculations via single antenna gain values.

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Vibrational Exfoliation of 2D Materials

Small, EarlyView.
Vibrational energy folds, fractures and exfoliates atomically and molecularly thin materials. Combining experimentation and computational methods, this unique vibrational synthesis pathway is revealed. This process overcomes barriers of existing approaches by processing 1000 g/L dispersions without loss in yield.

Accurate Sizing and Resolution of Nominal 200 nm Diameter Polystyrene Nanospheres With Charge Detection Mass Spectrometry

Small, EarlyView.
This study highlights the utility of charge detection mass spectrometry (CDMS) as a high‐throughput nanoparticle characterization tool. CDMS measurements of 200 nm polystyrene size standards are within 1% of those derived from transmission electron microscopy (TEM). Notably, a mixture of three ∼200 nm samples is readily resolved by CDMS but not by TEM,

Linguistic Variation across Instructional Segments in International Teaching Assistants' Discourse: A Corpus‐Based Analysis

TESOL Quarterly, EarlyView.
Abstract This study investigates internal linguistic variation in the instructional discourse of international teaching assistants (ITAs) by segmenting their mini‐lecture performances into four discourse types: introduction, lecture, conclusion, and audience interaction.
