The commonly used 1D phase correction can only correct phase difference along readout axis. 2D correction is, therefore, necessary when phase difference presents along both readout and phase encoding axes. However, existing 2D methods have several unaddressed issues that affect their practicality. ...
This work presents a novel optical holographic encrypted data storage approach based on a phase encoding multiplexed scheme. In the proposed data storage scheme, patterns to be encrypted are stored holographically in a photorefractive LiNbO 3 :Fe crystal using a lenticular lens array (LLA) sheet ...
Improving the phase sensitivity of an SU(1, 1) interferometer via a nonlinear phase encoding. J. Phys. B At. Mol. Opt. Phys. 2020, 53, 205503. [Google Scholar] [CrossRef] Xin, J.; Wang, H.; Jing, J. The effect of losses on the quantum-noise cancellation in the SU(1, 1) ...
An MRI apparatus comprises a magnet system producing a homogeneous magnetic field along the z axis. A plurality of wire conductors arranged in a bird cage configuration are supplied with a circularly rotating RF field centered near the Larmor frequency &ohgr;. sub.o. The wire conductors receive...
Figure 1shows a typical plot ofEb/Noversus probability of bit error (=BER), with and without coding. For a probability of bit error equal to 10−5, BPSK without coding givesEb/No=9.6dB. With rate−1/2,K=7 convolution encoding,Eb/No=4.4 dB, yielding a coding gain of 9.6–4.4=...
-striatal network at a shared 10–25 Hz beta frequency range. We found that for those neurons that phase-synchronize long-range, the three learning variables are encoded more precisely for spikes elicited at narrow oscillation phases in the beta band. This phase-of-firing gain of encoding ...
Disorder propensity is shown on the y axis, and amino acid position of RPA2 is on the x axis. h, RPA2 protein disorder prediction by PONDR (Predictor of Natural Disordered Regions)31. PONDR score is shown on the y axis, and amino acid position of RPA2 is on the x axis. Highly ...
(encoding). As expected, the decoder was able to differentiate between the picture categories when it was trained on FRs from the category neurons (hippocampus, 72.77%,P = 0.001; amygdala, 88.71%,P = 0.001; Extended Data Fig.7a). However, the decoder could not differentiate between...
In the projecting system, sinusoidal grating is perpendicular to optical axis. For moving the grating along a direction at a certain angle to optical axis, 1D precision translation platform is applied to achieve purposes of both phase-shifting and vertical scanning. A series of fringe patterns ...
