Fabrication tolerant flat-top interleavers

, 2017
Integrated circuits based on micron-scale silicon waveguides have the clear advantage of being tolerant to fabrication errors, thanks to the high mode confinement within the guiding core. Here we show how flat-top interleavers can be achieved on a micron-

SubDIVIDE: Efficient tensor‐valued diffusion magnetic resonance imaging via joint diffusional variance decomposition modeling and subspace reconstruction

Journal of Intelligent Medicine, EarlyView.
SubDIVIDE integrates a physics‐consistent DIVIDE subspace directly into MRI reconstruction. By embedding a low‐rank basis derived from a large DIVIDE signal dictionary into a joint ADMM optimization—together with composite sensitivity maps that absorb inter‐b‐value phase errors—the framework recovers quantitative microstructural maps from highly ...

Temporal dynamics of visual awareness and target detection revealed by EEG‐based univariate and multivariate analyses

Journal of Intelligent Medicine, EarlyView.
In this study, we combined univariate ERP analysis with multivariate decoding of EEG data to examine target detection and reported visual awareness in a near‐threshold visual task. The results revealed partly overlapping yet distinguishable temporal dynamics associated with the two processes.

Optimization and Implementation of DRAM-Based Interleavers for Free-Space Optical Communication Beyond 100 Gbit/s

IEEE Access
Optical transmission links from low earth orbit (LEO) satellites to earth require interleaving to ensure reliable data transmission. With data rate requirements beyond 100 Gbit/s and channel coherence times in the millisecond range, the capacity of on ...

Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...
