Food Frontiers, Volume 7, Issue 4, July 2026.This study investigated the dynamic changes of tea polyphenols (TP) during in vitro digestion of 24 representative tea varieties. Electronic nose and color difference technology were employed to construct predictive models, enabling estimation of TP content before and after digestion.

Wavelet Networks for Hyperspectral Image Classification
, 2007 高光譜影像因具有高維度之特性而無法直接應用傳統的統計分類方法進行影像分類。為了解決此問題，可在分類之前先進行高光譜影像特徵萃取；另一種可行之解決方式則是採用類神經網路進行影像分類。為了提高神經網路處理高維度資料的分類效率，可利用小波轉換進行高光譜影像特徵萃取，再以倒傳遞神經網路方法進行分類，然而小波特徵萃取法中，所選定的的尺度與平移參數並無法完全反應各類別光譜曲線的特性。本文提出利用小波神經網路法直接對高光譜影像進行分類，此方法在網路的學習過程中，同時對網路的權值、小波轉換的尺度及平移參數進行最佳化 ...

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.W(SxSe1−x)2, Te:WSSe, and WS2@WSSe nanotubes were synthesized through controlled precursor composition. The W(SxSe1−x)2 and Te:WSSe nanotubes exhibit small‐diameter (<30 nm), high‐yield, and well‐defined excitonic transitions. Composition tuning via S/Se ratios increases interlayer spacing with higher Se content. The incorporation of Te remains limited

Initial Assessment of the Detectability of Cyanotoxin Occurrence Using PACE Satellite Observations
Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract Microcystin is a major public health hazard during freshwater cyanobacterial blooms, yet its remote detection remains challenging because it lacks any direct optical absorption features. We demonstrate that hyperspectral observations from NASA's PACE Ocean Color Instrument (OCI) can be used to detect elevated microcystin concentrations by ...
