Effects of Green Tea Supplementation on Chemoprevention at Different Stages of Carcinogenesis: A Systematic Review

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Green tea catechins have chemopreventive potential; however, the clinical evidence remains inconsistent. This review evaluated the effects of supplementation with green tea derivatives on chemoprevention at different stages of carcinogenesis. PubMed, Embase, Web of Science, Scopus, the Cochrane Library, CINAHL, and Google Scholar were searched

Wavelet covariance approach to measure convective boundary‐layer structure

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study introduces a wavelet‐based framework that applies the Haar discrete wavelet transform (DWT) to radiosonde profiles of potential temperature and water vapor mixing ratio for diagnosing convective boundary‐layer (CBL) structure. The method objectively identifies key CBL parameters, including the surface‐layer height, entrainment zone depth ...

Improving heavy precipitation forecasts through phase‐aware nonlinear bias correction of all‐sky infrared radiances using cloud top temperature differences

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study proposes a phase‐aware bias correction framework for all‐sky infrared radiance assimilation. Cloud top temperature differences between observations and model background fields are used to identify cloud‐phase mismatch and cold‐cloud regimes.

Vulnerability to Dams of the Last Undammed Large Rivers of Southeast Asia

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The vast majority of large Eurasian rivers are regulated by hydropower dams, but some have survived as free‐flowing rivers so far in the Arctic and along stretches of the Myanmar coast. There, the Ayeyarwady (Irrawaddy) and Salween Rivers, two of the largest rivers of Southeast Asia, provide a huge amount of sediment, nurturing floodplains and
