Generating Reproducing Anoxia Conditions for Plant Phenotyping

open access: yesBio-Protocol, 2023
Based on the availability of oxygen, plant growth environment can be normoxic (normal environment), hypoxic (reduced oxygen, <21%), or anoxic (complete depletion of oxygen).

SSVEP detection assessment by combining visual stimuli paradigms and no-training detection methods

open access: yesFrontiers in Neuroscience, 2023
IntroductionBrain-Computer Interfaces (BCI) based on Steady-State Visually Evoked Potentials (SSVEP) have great potential for use in communication applications because of their relatively simple assembly and in some cases the possibility of bypassing the

Wakefields due to surface waves in a beam pipe with a periodic rough surface

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2002
The problem of the wakefields generated by an ultrarelativistic particle traveling in a long beam tube with a periodic rough surface has been revisited by means of a standard theory based on the hybrid modes excited in a periodically corrugated ...

A Stretchable Electromagnetic Absorber Fabricated Using Screen Printing Technology

open access: yesSensors, 2017
A stretchable electromagnetic absorber fabricated using screen printing technology is proposed in this paper. We used a polydimethylsiloxane (PDMS) substrate to fabricate the stretchable absorber since PDMS exhibits good dielectric properties ...
