Spatiotemporal analysis of optical imaging data
NeuroImage, 2003 Previous methods for analyzing optical imaging data have relied heavily on temporal averaging. However, response dynamics are rich sources of information. Here, we develop and present a method that combines principal component analysis and multitaper harmonic analysis to extract the statistically significant spatial and temporal response from optical ...

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters
Advanced Functional Materials, EarlyView.An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Advanced Functional Materials, EarlyView.Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Beyond Primary Nucleation: Molecular Basis of Peptide Crystal Secondary Nucleation at Soft Interface
Advanced Functional Materials, EarlyView.High spatiotemporal‐resolution atomic force microscopy directly resolved peptide secondary nucleation (SN) and growth characteristics and mechanisms on HOPG. The landscape of peptide nucleation sites, growth dynamics, molecular‐scale structures, phase transitions, and cross‐seeding processes were realized.

Spatiotemporal Barcodes for Image Sequence Analysis
, 2015 Taking as input a time-varying sequence of two-dimensional (2D) binary images, we develop an algorithm for computing a spatiotemporal 0–barcode encoding lifetime of connected components on the image sequence over time. This information may not coincide with the one provided by the 0–barcode encoding the 0–persistent homology, since the latter does not ...

Spatiotemporal nonlinearity in resting-state fMRI of the human brain
, 2008 In this work, the spatiotemporal nonlinearity in resting-state fMRI data of the human brain was detected by nonlinear dynamics methods. Nine human subjects during resting state were imaged using single-shot gradient echo planar imaging on a 1.5T scanner.
