Low-Profile and Low-Volume Split-Distributed Resonators and Filters

open access: yesIEEE Access, 2020
A new class of low-profile resonators, named split-distributed resonators is introduced in this paper. The newly proposed resonator family features high quality Q-factors and relies not only on the coupling among the constituent resonant elements, but ...

Numerical simulations of single whispering-gallery mode enhancement in hollow cylindrical optical microcavity [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2022
In this work, a hollow cylindrical optical microcavity is numerically investigated by finite-difference time-domain simulations. Enhancement of a single whispering-gallery mode (WGM) is realized by inserting a periodic hole array into the hollow ...

Resonant Characteristics of Rectangular Microcantilevers Vibrating Torsionally in Viscous Liquid Media [PDF]

open access: yes, 2012
The resonant characteristics of rectangular microcantilevers vibrating in the torsional mode in viscous liquid media are investigated. The hydrodynamic load (torque per unit length) on the vibrating beam due to the liquid was first determined using a ...

Micromechanically Tunable Dielectric Rod Resonator [PDF]

open access: yesInternational Journal of Electronics and Telecommunications, 2021
A resonant frequency control method for dielectric rod resonators is discussed. A dielectric rod of cylindrical shape is placed inside a metal cavity. The bottom face of the dielectric rod is fixed at the metal base plate.

Effect of Genistein and Glycitein on production performance, egg quality, antioxidant function, reproductive hormones and related-genes in pre-peak laying hens

open access: yesPoultry Science
: Genistein (GEN) and Glycitein (GLY), are types of isoflavone extracted mainly from soy plants, although GEN is associated with stronger antioxidant and growth-promoting effects. The impact of dietary GEN and GLY on reproductive performance, egg quality,

Quality and validity of large animal experiments in stroke : a systematic review [PDF]

open access: yes, 2020
An important factor for successful translational stroke research is study quality. Low-quality studies are at risk of biased results and effect overestimation, as has been intensely discussed for small animal stroke research.

Proteomic changes in extracellular vesicle and uterine fluid proteins correlated with eggshell quality in aged laying hens

open access: yesPoultry Science
Extracellular vesicles (EVs) in uterine fluid (UF) are thought to regulate eggshell calcification, yet their composition and functions remain unclear.
