Impact Analysis of Baseband Quantizer on Coding Efficiency for HDR Video
, 2016 Digitally acquired high dynamic range (HDR) video baseband signal can take 10 to 12 bits per color channel. It is economically important to be able to reuse the legacy 8 or 10-bit video codecs to efficiently compress the HDR video.

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes
Advanced Physics Research, EarlyView.This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks
Chemistry – A European Journal, EarlyView.A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Highly efficient sky‐blue LED with EQE of 13.6% is realized through short‐chain ligand tridecylamine treaded perovskite quantum dots, due to the suppressed non‐radiative recombination from the trap state. These results indicate that the ligand with strong affinity can facilitate the surface defects passivation, resulting in enhanced optical properties,

Characterizing the contaminating distance distribution for Bayesian supernova cosmology
, 2010 Measurements of the equation of state of dark energy from surveys of thousands of Type Ia Supernovae (SNe Ia) will be limited by spectroscopic follow-up and must therefore rely on photometric identification, increasing the chance that the sample is ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.
