An efficient algorithm for codebook design in transform vector quantization
, 2003 In this paper, a new wavelet-domain codebook design algorithm is proposed for image coding. The method utilizes mean-squared error and variance based selection schemes for good clustering of data vectors in the training space.

Machine Learning–Enhanced Fluorescence Cryptography with NADH‐Responsive Polymer Dots
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This study presents a smart anticounterfeiting system using semiconducting polymer dots (Pdots) that exhibit tunable fluorescence responses to NADH. By integrating these dynamic optical signals with machine learning–based decoding, the work establishes a secure and intelligent encryption platform, showing a novel strategy that links chemical sensing ...

Left Wanting and Left Unheard: A Dual Grievance Model of Populism Across Six European Countries
European Journal of Social Psychology, EarlyView.ABSTRACT This study tests a dual grievance model of populism by examining whether relative deprivation and external political inefficacy are linked to two core dimensions of populist beliefs (people sovereignty and anti‐elitism) via aversive political emotions (anger, sadness and fear) and institutional distrust across six European countries (N = 5487).

The Role of Coincident Information in Real‐Time Business Cycle Forecasting
Journal of Forecasting, EarlyView.ABSTRACT Official NBER recession dates are announced with substantial delay. Therefore, real‐time forecasters cannot condition on the most recent business cycle states even though recessions and expansions are highly persistent. I study whether real‐time coincident releases can substitute for this missing information. At each monthly forecast origin, I
