Anatomy-guided Inverse-phase-encoding Registration Method for Correcting Susceptibility Artifacts in Sub-millimeter fMRI

Evaluations on two high-resolution EPI-fMRI datasets, acquired at 3T and 7T scanners, confirm that the proposed method provides more robust and sharper corrections and runs faster compared with two other state-of-the-art inverse-PE based susceptibility artifact correction methods, i.e. Expand abstract.

Unsupervised Learning for Real-World Super-Resolution

Our super-resolution network can therefore be trained with direct pixel-wise supervision in the high resolution domain, while robustly generalizing to real input. Expand abstract.

PgNN: Physics-guided Neural Network for Fourier Ptychographic Microscopy

Fourier ptychography (FP) is a newly developed computational imaging approach that achieves both high resolution and wide field of view by stitching a series of low-resolution images captured under angle-varied illumination. Expand abstract.

Inversion of lattice models from the observations of microscopic degrees of freedom: parameter estimation with uncertainty quantification

This suggests that microscopic observations of materials with sufficiently high precision can provide information on generative physics at temperatures well above corresponding phase transition, opening new horizons for scientific exploration via high-resolution imaging. Expand abstract.

Coupling chromatin structure and dynamics by live super-resolution imaging

In combination with high-resolution dense motion reconstruction, we confirm the existence of elongated ~ 45 to 90 nm wide chromatin blobs, which appear to be dynamically associating chromatin fragments in close physical and genomic proximity and adopt TAD-like interactions in the time-average limit.

An adaptive parareal algorithm

At convergence, the parareal algorithm provides a solution that has the fine solver's high-fidelity physics and high resolution In the classical version of parareal, the fine solver has a fixed high accuracy which is the major obstacle to achieve a competitive parallel efficiency. Expand abstract.

Integrated Low-Energy and Low Carbon Shortcut Nitrogen removal with Biological Phosphorus Removal for Sustainable Mainstream Wastewater Treatment

Importantly, high resolution process monitoring coupled to ex situ batch activity assays demonstrated that robust biological P removal was coupled to energy and carbon efficient nitritation-denitritation, not simultaneous nitrification-denitrification, for the last400 days of 531 total days of operation.

Thinking small: next-generation sensor networks close the size gap in vertebrate biologging

Our developments highlight the vast capabilities of WBNs and their potential to close an important gap in biologging: fully automated tracking and proximity sensing of small animals, even in closed habitats, at high spatial and temporal resolution. Expand abstract.
