Self‐encapsulated light‐emitting conjugated polymers with enhanced spectra aging stability for deep‐blue polymer light‐emitting diodes

InfoMat, EarlyView.
Toward enhancing the spectral air‐aging stability of blue light‐emitting conjugated polymers in solution‐processed manufacturing, we proposed a design approach for molecular‐level encapsulation by introducing dendritic carbazoles (Cz) to the side chains.

Temporary VAT Reduction in Vietnam: Consumer Behavior Analysis

International Studies of Economics, EarlyView.
ABSTRACT This study investigates the impact of temporary VAT rate changes on consumer behavior in Vietnam, particularly concerning the VAT reduction implemented during 2023–2024. The research analyzes annual survey data and household expenditure reports to assess changes in consumer spending on durable goods during the first half of 2024 (2024 H1 ...

Optimized reconstruction of the absorption spectra of kidney tissues from the spectra of tissue components using the least squares method

Journal of Biophotonics, EarlyView.
The absorption coefficient spectra of healthy and cancerous kidney tissues were reconstructed from the absorption spectra of tissue components using constant weights. Both reconstructions allowed to calculate the concentrations of the tissue components and a comparison between the healthy and chromophobe renal cell carcinoma kidney showed an increase ...

Optical method supported by machine learning for dynamics of C‐reactive protein concentrations changes detection in biological matrix samples

Journal of Biophotonics, EarlyView.
The proposed method is based on an optical system supported by machine learning, that allows to monitoring dynamic of C‐reactive protein (CRP) level changes in near‐real time. Monitoring the presence level of CRP in wastewater might be used to track the spread of diseases or identify areas with increased morbidity.

When Does Top Management Team Diversity Matter in Large Organizations?

Journal of Organizational Behavior, EarlyView.
ABSTRACT Top management teams (TMTs) drive strategic leadership, but there is little clarity on when the composition of these upper echelons most impacts organization performance. Drawing from the categorization‐elaboration model, we study an 18‐year sample of approximately 4500 organizations and over 32 000 executives and find a positive relationship ...

Ultra‐Compact Broadband Spot Size Converter Using Metamaterial Cell‐Based Inverse Design

Laser &Photonics Reviews, EarlyView.
Inverse design techniques are combined with subwavelength structures to design a compact, high‐performance spot size converter. A cell‐based topology is proposed, where each cell is composed of an equivalent homogenous metamaterial, resulting in a reduced parameter that speeds up optimization. A 7 μm$\mu{\rm m}$‐long device that achieves a 24‐fold beam
