Ultrasound‐Activatable Piezoelectric Hydrogel Reprograms Mitochondrial Epigenetics for Osteoarthritis Therapy via the mTOR/GATD3A Axis

Advanced Science, EarlyView.
An ultrasound‐activatable piezoelectric hydrogel reprograms chondrocyte mitochondrial epigenetics via the mTOR/GATD3A axis, clearing damaged mitochondria and alleviating osteoarthritis progression in both mouse models and human cartilage explants. ABSTRACT The avascular nature of cartilage hinders drug delivery for osteoarthritis (OA) therapy.

Antenna factors of dipole and monopole antennas

Proceedings of 20th Biennial Conference on Precision Electromagnetic Measurements, 2002
Antenna factors of dipole antennas in the frequency range 20 MHz to 600 MHz have been determined to an uncertainty of /spl plusmn/0.1 dB (95%CL) and of monopole antennas in the range 10 MHz to 100 MHz to an uncertainty of /spl plusmn/0.15 dB. This leads to an advance in the precision with which electric field strength of free-space signals can be ...

Modified folded dipole antenna

Proceedings of the International Conference & Workshop on Emerging Trends in Technology - ICWET '11, 2011
This paper describes experimentally how a folded dipole antenna is better in performance than a simple dipole antenna and also describes an alternate way to design folded dipole antenna compatible with loop antenna to generate circular polarized wave.
