Geometrically-Inspired Sparse MIMO Array Design for Enhanced mm-Wave Near-Field Imaging

IEEE Access
In this paper, an efficient method of sparse MIMO array design is proposed to enhance the millimeter-wave near-field imaging by utilizing the geometric properties of the virtual array with uniform coverage of two-dimensional aperture and the minimal ...

Coincident Fluorescence‐Burst Analysis of Actin Cargo Molecules in Secreted Single Diffusing Extracellular Vesicles From Human Induced Pluripotent Stem Cells

Advanced Science, EarlyView.
This study presents a two‐color FCCS and coincident‐burst analysis platform to quantify actin cargo in dual‐labeled EVs secreted from hiPSCs. The approach tracks secretion dynamics, confirms actin loading, and measures EV size and cargo number, offering insights into cytoskeletal disruption and neuronal differentiation relevant to neurodegenerative ...

Autophagy Activators Normalize Aberrant Tau Proteostasis and Rescue Synapses in Human Familial Alzheimer's Disease iPSC‐Derived Cortical Organoids

Advanced Science, EarlyView.
A new cerebrocortical organoid model using isogenic hiPSCs with familial Alzheimer's mutations recapitulates key AD features, including amyloid‐beta and phospho‐Tau aggregation, neuronal hyperexcitability, and synapse loss. Single‐cell RNA‐seq reveals aberrant pathways in excitatory and inhibitory neurons.

Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Spectral Decomposition of Chemical Semantics for Activity Cliffs‐Aware Molecular Property Prediction

Advanced Science, EarlyView.
PrismNet mimics chemical intuition by functioning as a computational prism, refracting molecular graphs into complementary semantic views and spectral frequencies. This dual‐decomposition strategy effectively captures both global topologies and subtle “activity cliff” perturbations.
