Modeling Light‐Induced Synaptic Behavior and Visual Memory of Azopolymeric Compounds

Advanced Optical Materials, Volume 14, Issue 29, 7 August 2026.
In the framework of neuromorphic hardware it is essential to predict the evolution of the internal state of the devices mimicking synaptic functionalities to perform in‐silico modeling of specific computational tasks. Here, we provide a rate‐balance equation model to describe the synaptic‐like response of light‐actuated azopolymeric compounds and ...

Hadamard Matrix Slicing Single‐Pixel Imaging: Establishing a Linear‐Array‐Inspired Paradigm for N‐fold Acceleration Single‐Pixel Imaging

Advanced Science, Volume 13, Issue 43, 3 August 2026.
To overcome two‐dimensional modulation bottlenecks, Hadamard Matrix Slicing Single‐Pixel Imaging (HMS‐SPI) establishes an efficient one‐dimensional imaging paradigm. By slicing the traditional Hadamard matrix into one‐dimensional encoding vectors and spatially expanding them, the required measurement patterns decrease by a factor of N.

Hardware‐Attentive Programmable Fourier Ptychography Enables Task‐Adaptive Label‐Free Virtual Staining

Advanced Science, Volume 13, Issue 46, 17 August 2026.
Task‐adaptive programmable optics enables label‐free virtual staining through optical‐attention‐guided acquisition and reconstruction. By optimizing wavelength, illumination angle, exposure time, and imaging depth, the framework learns task‐relevant optical measurements, generating clinically interpretable virtual stains with improved fidelity, non ...

Invariant Consistent Dynamic Mode Decomposition

, 2023
Any deterministic autonomous dynamical system may be globally linearized by its' Koopman operator. This object is typically infinite-dimensional and can be approximated by the so-called Dynamic Mode Decomposition (DMD).

Unforgeable Red: Design and Application of SO‐Annulated Perylene Diimides for Anti‐Counterfeiting

Small, Volume 22, Issue 46, 18 August 2026.
Sulfoxide‐annulated derivatives were synthesized as photoactive chromophores and implemented in photopatterning processes to design anti‐counterfeiting signatures with a double level of authentication. Patterns ranging from centimeter to micrometer size were obtained with high definition, and thereafter these approaches were tested in potential market ...
