A high modulation depth of >90% has been shown by employing graphene in place of a metal gate in an AlGaAs/GaAs two-dimensional electron-gas (2DEG) terahertz modulator, which provides a modulation of <30 only [70].
To circumvent this problem, OQAM modulation can be applied, which provides orthogonality but still keeps the advantageous property of good time-frequency localization.
In this paper we presented an all-optical modulator based on Si slab resonator for future in-fibre integrated modulations with increased finesse due to coating on both sides of the slab which provides sufficient modulation depth.
In [12], the authors designed a spectral efficiency transmission scheme, labeled as bit-interleaved coded spatial modulation (BICSM) with iterative demodulating/decoding, which provides substantial performance gains in all channel conditions.
The BOC-like SS-CPM signal maintains the constant envelope at transmission and less out-band emission in radio determination satellite service (RDSS) band, which provides a reference modulation for COMPASS satellite navigation signal.
These findings show that GITR signalling can regulate the extent of sympathetic neurite growth through an inverse modulation of Erk and NF-κB signalling, which provides an optimal environment for NGF-promoted growth.
We also found a correlation between the strength of normalization modulation and attentional modulation for some of our comparisons (see Fig. 5), which provides partial support for the normalization model of attention.
Here we observe the predicted density modulation of this stripe phase using Bragg reflection (which provides evidence for spontaneous long-range order in one direction) while maintaining a sharp momentum distribution (the hallmark of superfluid Bose Einstein condensates).
These findings suggest that high-value reward may facilitate human higher-order inhibitory processes that are independent of conscious awareness, which provides insights into the brain processes that underpin motivational modulation of cognitive control.
This new finding demonstrates that the modulation of interlayer spacing of pillared graphene oxides could enhance their CO2 adsorbability, which provides useful information to design graphene-based materials with superior CO2 adsorption capacity.
