Arabidopsis cryptochrome is responsive to Radiofrequency (RF) electromagnetic fields. [PDF]
Sci Rep, 2020 How living systems respond to weak electromagnetic fields represents one of the major unsolved challenges in sensory biology. Recent evidence has implicated cryptochrome, an evolutionarily conserved flavoprotein receptor, in magnetic field responses of ...

T2 Relaxation during Radiofrequency (RF) pulses [PDF]
, 2023 Radiofrequency (RF) pulses are a critical part of every MRI pulse sequence, and must be specifically designed for ultrashort echo time (UTE) and zero echo time (ZTE) acquisitions.

Selective tumor heating by shortwave radiofrequency (RF) [PDF]
Cancer, 1980 Experimental solid tumors were treated in vivo with external high frequency dielectric heating to observe any heat selectivity between the tumor mass on one hand, and the subcutaneous tissue, muscle, and systemic temperatures on the other. Methylcholantrene-induced sarcoma cells were inoculated into the subcutaneous tissue or muscles of the posterior ...

Cooled radiofrequency (RF) of L5 dorsal ramus for RF denervation of the sacroiliac joint: technical report. [PDF]
Pain Medicine, 2010 The sacroiliac joint is a common source of chronic low back pain. We recently described the use of cooled radiofrequency (RF) electrodes for performing lateral branch neurotomy to treat sacroiliac joint pain. The procedure involves lesioning the lateral branches of the posterior primary rami at S1-S3, and the L5 dorsal ramus (L5DR). While the cooled RF

Detection of Lunar Regolith Acquired by Excavator Using Radiofrequency (RF) Sensors. [PDF]
Sensors (Basel)This paper presents the concept of a radiofrequency (RF) sensor designed to estimate the mass of the regolith acquired by a sampling device or excavator in planetary environments. The sensor utilizes a microstrip line with an open end as the sensing element, with the mass estimation based on measurements of the phase of the reflection coefficient (S11 ...

Radiofrequency identification of wireless devices based on RF fingerprinting
Electronics Letters, 2013 A radiofrequency (RF) fingerprinting strategy for the proper identification of wireless devices in mobile and wireless networks is proposed. The main objective is the extraction of the main parameters of the RF signal of the device by means of the preamble in the communication in the wireless network.
