Subicular Astrocytes Govern Seizure‐Impaired Fear Memory
Advanced Science, EarlyView.Astrocytes in dorsal subiculum act as a critical modulator of seizure‐associated cognitive dysfunction, operating through a Ca2+‐dependent adenosine‐linked astrocyte‐neuron signaling pathway that disrupts neuronal circuit homeostasis. This research highlights the potential of astrocyte‐targeted interventions as a therapeutic strategy, moving beyond the

Advanced Science, EarlyView.This study quantitatively evaluates randomized DNA sequence design for digital data storage using three physics‐based models. By applying encoding schemes with strict homopolymer constraints, the framework improves base randomness, GC balance, and error resilience. Experimental validation via PCR and Sanger sequencing confirms 95–98% decoding accuracy,

High Quality Audio Coding with Mdctnet
ICASSP 2023 - 2023 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2023 We propose a neural audio generative model, MDCTNet, operating in the perceptually weighted domain of an adaptive modified discrete cosine transform (MDCT). The architecture of the model captures correlations in both time and frequency directions with recurrent layers (RNNs).

Magnetic Flux Guides by Material Extrusion
Advanced Science, EarlyView.Magnetic flux guidance can increase inductive coupling and forces for magnetic sensors, actuators, and transducers. Here, a magnetic material extrusion method is used to fabricate flux concentration structures of arbitrary shapes with a magnetic permeability of 42. In line with simulation analysis, experimental results show that these materials provide

Signal, Image and Video Processing, 2013 In this paper, a new audio coding scheme combining the Hilbert transform and the empirical mode decomposition (EMD) is introduced. Based on the EMD, the coding is fully a data-driven approach. Audio signal is first decomposed adaptively, by EMD, into intrinsic oscillatory components called intrinsic mode functions (IMFs).

Scalable Photoactive NO2‐Sensing Framework for Plant Health Monitoring
Advanced Science, EarlyView.A highly sensitive and selective NO2 gas sensor operates at room temperature using only ambient light, eliminating the need for external heating. Based on a scalable, 3D TiO2 nanoarchitecture, the device is integrated into a wireless platform and deployed on a plant. It successfully demonstrates real‐time monitoring of gas‐induced physiological stress,
