Gram‐Scale Synthesis of Hafnium‐Rich Carbon Dots for Preclinical Computed Tomography Imaging Across Various Systems

Advanced Science, EarlyView.
Hafnium (Hf)‐rich carbon dots (Hf‐rCDs) with high metal content (40.7%) and robust batch production capacity (>2 g per batch) are synthesized via a facile air‐assisted pyrolysis method. In vivo CT imaging demonstrates outstanding performance of Hf‐rCDs across multiple physiological systems and enables high‐resolution visualization of swine cervical ...

Improve Akaike’s Information Criterion Estimation Based on Denoising of Quadrature Mirror Filter Bank

Al-Khawarizmi Engineering Journal, 2019
Akaike’s Information Criterion (AIC) is a popular method for estimation the number of sources impinging on an array of sensors, which is a problem of great interest in several applications. The performance of AIC degrades under low Signal-to-Noise Ratio (

Polarization‐Dependent 3D Holography Generated by Inverse Design Nanoprinting Metasurface

Advanced Science, EarlyView.
A novel polarization‐dependent 3D holography is proposed by introducing polarization as an additional freedom, enabling enhanced depth selectivity and greater control over holographic reconstruction. The efforts perfectly combine the polarization and 3D holography display into ADAM gradient descent algorithm, the application of nanoprinting further ...

Atomically Precise Clusterzymes: A Programmable Optoelectronic Platform for Neuroscience

Advanced Science, EarlyView.
Atomically precise clusterzymes, engineered via atomic and ligand design, serve as programmable platforms for neuroscience applications. They demonstrate tailored biocatalysis for neuroinflammation, tunable optical properties for deep‐tissue bioimaging and 3D visualization, and enhanced charge transfer for brain–computer interfaces.

Multimodal Layer‐Crossing Interrogation of Brain Circuits Enabled by Microfluidic Axialtrodes

Advanced Science, EarlyView.
The study introduces a flexible microfluidic axialtrode that integrates optical, electrical, and chemical modalities within a single polymer fiber. By redistributing electrodes and fluidic channels along the fiber axis via angled cleaving, it enables simultaneous optogenetic stimulation, electrophysiological recording, and drug delivery across brain ...

Label‐Free and Immobilization‐Free Protein‐Binding Assays by Ultraviolet Transient Absorption Microscopy

Advanced Science, EarlyView.
A femtosecond UV pump–probe microscope resolves binding‐induced changes in protein excited‐state dynamics and converts these intrinsic contrasts into an equilibrium affinity readout. By probing tryptophan responses directly in solution, the approach enables quantitative determination of dissociation constants without labeling or immobilization ...

Analisa dan Perancangan Aplikasi Bantu Perbaikan Signal to Noise Ratio (SNR) Dengan Metode Flat-Top Sampling

CCIT Journal, 2010
Noise adalah bunyi yang tidak diinginkan dengan bentuk gelombang yang tidak periodik yang terdapat dikeluaran sistem atau dibagian manapun dalam sistem itu yang biasanya timbul ketika proses perekaman. Noise dapa menyebabkan bunyi atau sinyal suara yang diharapkan menjadi lemah atau bahkan hilang.
