Trions as Fundamental Species in Chemically Doped Polymer Semiconductors
Advanced Materials, EarlyView.This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Control Architectures for Metamaterials in Vibration Control
2023 IEEE International Conference on Mechatronics (ICM), 2023Metamaterials are artificial structures with properties that are rare or non-existent in nature. These properties are created by the geometry and interconnection of the metamaterial unit cells. In active metamaterials, sensors and actuators are embedded in each unit cell to achieve greater design freedom and tunability of properties after the ...

Developments in Vibrator Control
EAGE Vibroseis Workshop - Vibroseis acquisition and processing half century later, new developments in data quality and productivity, 2008ABSTRACTHydraulic limitations, non‐rigidity of the baseplate as well as variable characteristics of the ground constantly distort the downgoing energy output by vibrators. Therefore, a real time feedback control must be performed to continuously adjust the emitted force to the reference pilot signal. This ground force is represented by the weighted sum

The Journal of the Acoustical Society of America, 2006
A vibration controller includes a map controller, an adaptive controller, a set-up frequency judge/switcher, and an actuator. The map controller includes a data map storage for storing data on control signals determined in advance for a vibration insulator, and a signal generator for selecting one of the data, depending on a frequency of a cyclically ...

Vibrator, vibration unit, and vibrator control method
The Journal of the Acoustical Society of America, 2006A vibrator has massaging balls supported by a treating unit that may be shifted along a subject portion for treatment, guided by guiding members. The treating unit is supported by a supporting structure with respect to the guiding members. A position or orientation altering mechanism is provided for altering the position of the treatment unit in a ...
