Evaluation of BER for the EHF Communication System Serving Sharp-Coned Reentry Vehicles

Frontiers in Earth Science, 2022
“Communication blackout” could lead to severe risks to reentry vehicles. Previous studies have shown that EHF (extremely high frequency) communication is a potential solution to the “communications blackout” and was mostly used for blunt-coned vehicles ...

Extremely low frequency‐based faulty line selection of low‐resistance grounding system

IET Generation, Transmission & Distribution, 2021
The single‐phase‐to‐ground faulty line selection methods based on the signals of the frequency above 10 Hz has a low discrimination of fault characteristic signal and characteristic signal may be covered by noise in cases of high‐resistance fault.

Volume Targeted Ventilation and High Frequency Ventilation as the Primary Modes of Respiratory Support for ELBW Babies: What Does the Evidence Say?

Frontiers in Pediatrics, 2020
Respiratory management of the extremely low birth weight (ELBW) newborn has evolved over time. Although non-invasive ventilation is being increasingly used for respiratory support in these ELBW infants, invasive ventilation still remains the primary mode

A long-term responding epidermal growth factor receptor mutated non-small cell lung cancer patient with extremely high mutation allele frequency

Contemporary Oncology, 2022
Epidermal growth factor receptor (EGFR) mutation is the most frequent oncogenic driver in non-small cell lung cancer (NSCLC) [1, 2]. Among EGFR mutations, exon 19 deletion and exon 21 L858R are two of the most common mutations; hence they are referred to

Effect of acoustic pulses and EHF radiation on multipotent marrow stromal cells in tissue engineering constructs [PDF]

Journal of Innovative Optical Health Sciences, 2017
In this paper, we studied the effects of physical factors, such as, acoustic pulses of laser-induced hydrodynamics (ALIH) and extremely-high frequencies (EHF) radiation, on the formation of heterotopic bone marrow organs.
