Define phase modulation. phase modulation synonyms, phase modulation pronunciation, phase modulation translation, English dictionary definition of phase modulation. n. Abbr. pm or p-m A method of signal transmission in which the phase of a carrier wave i
For binary n-1 it is called as Binary ASK (BASK) Or On off Keying Technique (OOK) [20]. Bandwidth is directly proportional to baud rate of Message signal m (t). B∝rB∝rE22 B=(1+d)rB=1+drE23 Where d is the factor for modulation and filtering process (Range 0 for ideal case...
aThis paper described an automatic modulation-scheme recognisation technique for use in a software radio system.The technique is capable of determining the modulation scheme of a signal in the case when the modulation scheme class is not known a priori, and can be used for both digital and an...
[145,156]. This technique is generalizable to biological outcomes beyond survival, by sorting or enriching cells with attributes of interest. Cell lines have also been generated to express a fluorescent protein when a signaling pathway is activated, which then can be processed for cell enrichment ...
It performs inversions with the simultaneous iterative reconstruction technique (SIRT, Peterson et al., 1985). SIRT calculations modify an initial velocity model by repeated cycles in three steps: forward computation of model travel times, calculation of residuals and application of velocity corrections ...
Next, we investigated the possible membrane potential modulation upon irradiation in HEK293T cells loaded with different concentrations of MTP2 (5 and 10 µM in saline) through the patch-clamp technique in whole-cell current-clamp configuration. Cells were stimulated with 20 ms light pulses...
[30]. In an analogy to the technique of remote ischemic conditioning, scientists have coined the term “remote PBM” to describe this phenomenon [30]. Despite the limited understanding of its mechanisms to date, experimental animal studies have reported some neuroprotective effects of remote PBM ...
3D bioprinting is the utilization of 3D printing technique to integrate cells, growth factors, and/or biomaterials, aiming to fabricate biomedical components. The application of this technology to study liver disease emerged only a few years ago. 3D bioprinting facilitates the spatially coordinated grow...
This technique induces highly localized and transient temperature changes at the cell membrane interfaced with photothermally active nanomaterials. This rapid temperature change affects the electrical properties of the cell membrane or temperature-sensitive ion channels. In this Review, we discuss the ...
