The Ras protein family is involved in signal transduction, and their activation leads to growth, differentiation and cellular survival. NF1 has been recently identified as important in the development of acute myelogenous leukemia (AML) [14], the same form of leukemia that is associated with ...
Apparatus for providing timing jitter tolerant optical modulation of a first signal by a second signal, the first signal having a first wavelength, the second signal including a plurality of second signal pulses having a second pulse shape and a second wavelength. The apparatus includes a first si...
When a to-be-modulated digital signal is provided from a code generator , a bidirectional shift register allows a bit-row with sixteen bits to shift in circulation in a direction determined in accordance with a logic value of the supplied digital signal. Weighting adders I and Q weight and ...
Abstract In this paper we investigate an alternate, RI-modulation (R = real, I = imaginary) \{AMS\} framework for speech enhancement, in which the real and imaginary parts of the modulation signal are processed in secondary \{AMS\} procedures. This framework offers theoretical advantages over...
The present invention discloses a signal modulation recognition method based on feature extraction, for the received signal, first calculate the number of peaks when its normalized power spectrum and the normalized power spectrum is greater than the constant B K; then according to K value, ...
Here we put forward a theory in which a stochastic modulatory signal induces shared variability in neural responses, which then serves as a label for task relevance. We examine its implications in the context of a change detection experiment in non-human primates20,21, with blocked task switching...
Engaging the noncentrosymmetric components of the susceptibility at high input powers allows the nonlinear generated signal to surpass the linear chiroptical contrast exhibited by the chiral structure8,31,32,33,34. Here we utilize the off diagonal terms of the electric permittivity tensor to manipulate...
Immunotherapy is a rapidly evolving field in the treatment of cancer. It involves harnessing the body’s immune system to recognize, target, and eliminate cancer cells. Several types of immunotherapy strategies have shown promising results in treating various cancers. These involve developing ICIs inclu...
a由于研究人员分析信号特征时,为方便分析,都采用了正弦信号,且在2ASK调制方式中也是使用正弦波作为调制信号的载波,故在设计井下无线发射电路时应该设计正弦波产生电路。 Because the researcher analyzes time the signal characteristic, is the convenience analysis, all has used the sine signal, also also is uses...
