Effectiveness of adjusted bandwidth knowledge of results in motor learning

open access: yesCogent Psychology, 2022
Introduction: Knowledge of results (KR) is a method of augmented feedback where frequency or timing varies depending on the individual’s performance. In previous studies, bandwidth (BW) KR was not established according to the individual’s performance ...

Double-armed cone-shaped flexoelectric transducer

open access: yesFrontiers in Physics, 2023
Compared with a single energy harvester, this tuning fork double-armed cone-shaped flexure transducer can fundamentally solve the problems of high resonance frequency, low output efficiency, and narrow bandwidth of the flexure transducer.

Cascaded forward Brillouin scattering to all Stokes orders

open access: yesNew Journal of Physics, 2017
Inelastic scattering processes such as Brillouin scattering can often function in cascaded regimes and this is likely to occur in certain integrated opto-acoustic devices.

Bootstrapping techniques to improve the bandwidth of transimpedance amplifiers. [PDF]

open access: yes, 1998
Transimpedance amplifiers using voltage feedback operational amplifiers are widely used for current to voltage conversion in applications when a moderate/high bandwidth and a high sensitivity are required, such as photodiodes, photomultipliers, electron ...

Optimizing the Performance of Pure ALOHA for LoRa-Based ESL

open access: yesSensors, 2021
(1) Background: The scientific development in the field of industrialization demands the automization of electronic shelf labels (ESLs). COVID-19 has limited the manpower responsible for the frequent updating of the ESL system.

On cross-bandwidth

open access: yesDiscrete Mathematics, 1981
AbstractThe notion of cross-bandwidth is introduced, and it is shown that any graph that is suitably contractible to a k-connected graph has cross-bandwidth at least k. The contracted edges must induce in the original graph a subgraph of maximum degree at most one.

Free-carrier-induced soliton fission unveiled by in situ measurements in nanophotonic waveguides

open access: yesNature Communications, 2016
Solitons are nonlinear waves that exist in diverse forms of matter. Here, Husko et al. use near-field measurements to observe the spatio-temporal evolution of optical pulses in a nanophotonic semiconductor waveguide, demonstrating that nonlinear photo ...
