Improved Transformer-Based Dual-Path Network with Amplitude and Complex Domain Feature Fusion for Speech Enhancement.
Ye M, Wan H. Ye M, et al. Entropy (Basel). 2023 Jan 26;25(2):228. doi: 10.3390/e25020228. Entropy (Basel). 2023. PMID: 36832595 Free PMC article.
Recently, there have also been some methods to choose complex features, but complex masks are difficult to estimate. Removing noise while maintaining good speech quality at low signal-to-noise ratios is still a problem. This study proposes a dual-path network struct …

Ptychographic ultrahigh-speed imaging.
Sidorenko P, Lahav O, Cohen O. Sidorenko P, et al. Opt Express. 2017 May 15;25(10):10997-11008. doi: 10.1364/OE.25.010997. Opt Express. 2017. PMID: 28788786 Free article.
We propose and demonstrate numerically a simple method for ultrahigh-speed imaging of complex (amplitude and phase) samples. Our method exploits redundancy in single-shot ptychography (SSP) for reconstruction of multiple frames from a single camera snapshot. ...We d …

Investigations into within- and between-subject resting-state amplitude variations.
Bijsterbosch J, Harrison S, Duff E, Alfaro-Almagro F, Woolrich M, Smith S. Bijsterbosch J, et al. Neuroimage. 2017 Oct 1;159:57-69. doi: 10.1016/j.neuroimage.2017.07.014. Epub 2017 Jul 13. Neuroimage. 2017. PMID: 28712995 Free PMC article.
Therefore, improving our understanding of amplitude fluctuations over the course of a resting state scan and variation in amplitude across individuals is of great relevance to the interpretation of FC findings. ...Our findings additionally reveal complex rela …

Noise-Induced Network Topologies.
Folz F, Mehlhorn K, Morigi G. Folz F, et al. Phys Rev Lett. 2023 Jun 30;130(26):267401. doi: 10.1103/PhysRevLett.130.267401. Phys Rev Lett. 2023. PMID: 37450810
The network dynamics results from the interplay between a nonlinear function of the flow, dissipation, and Gaussian, additive noise. For a given set of parameters and finite noise amplitudes, the network self-organizes into one of several metastable configurations, accordi …
