Abstract Aerosols have significant and complex impacts on regional climate in East Asia. Cloud‐aerosol‐precipitation interactions (CAPI) remain most challenging studies. The quantitative understanding of CAPI requires good knowledge aerosols, ranging from their formation, composition, transport, radiative, hygroscopic, microphysical properties. A comprehensive review is presented here centered the based chiefly, but not limited to, publications special section named EAST‐AIRcpc concerning...

Significance Historians have long debated the role of climate in rise and fall empires 1st millennium CE. Drastic territorial contraction Byzantine Empire, societal decline, beginning European Middle Ages generally been linked to Islamic conquests seventh century. This multidisciplinary archaeological investigation trash mounds Negev Desert establishes end date organized management Byzantine-period city Elusa demonstrates urban collapse a century before transition. Our findings, taken...

Surface water is the most important resource and environmental factor in maintaining human survival ecosystem stability; therefore, timely accurate information on dynamic surface urgently needed. However, existing datasets fall short of current needs various organizations disciplines due to limitations optical sensors mapping. The advancement cloud-based Google Earth Engine (GEE) platform free-sharing Sentinel-1 imagery makes it possible map dynamics a body with high spatial-temporal...

Wetlands play an important role in supporting biodiversity conservation and helping sustainable development. Time series wetland classification requires a of sample sets acquired at different times. To meet this need, we proposed method for automatically producing global samples based on 13 regional wetland-related datasets millions images from Landsat 8 Operational Land Imager (OLI), Moderate Resolution Imaging Spectroradiometer (MODIS), Sentinel-1 Synthetic Aperture Radar (SAR) Ground...

ABSTRACT Radiocarbon ( 14 C) dating of anthropogenic carbonates (CaCO 3 ) such as ash, lime plaster and mortar, has proven a difficult task due to the occurrence number contaminants embedded within CaCO pyrogenic binder. These include C-free geologic components and/or secondary phases bearing an unknown amount C, thus alteration original isotopic signature material results in major age offsets when carbon recovery is performed through acid hydrolysis. Here we present...

Deposits rich in bioarchaeological materials were unearthed two dovecotes found near Sa'adon, a Byzantine-period village (5th–6th century CE) the semi-arid part of Negev. One structure contained layer pigeon manure and articulated skeletons, preserved occupation levels evidence sudden destruction (mid-6th CE), whereas other lacked distinct debris indicting more orderly human abandonment. Our findings demonstrate importance raising pigeons for their high-quality connection with agricultural...

As one of the most important steps in classification and mapping research, sample acquisition updating cost a lot time energy researchers. The high temporal spatial dynamic characteristics wetland make reliable selection more challenging. It is especially for series to address problem how apply sets images with different periods. This article evaluated reliability historical samples by using optical synthetic aperture radar remote sensing data from perspective water inundation frequency,...

Abstract BACKGROUND Products with high concentrations of polyunsaturated fatty acids (PUFAs) are now in demand for health care and medicine. In this work, a novel lipase‐catalyzed ethanolysis low‐grade fish oil was developed combined use two commercial free immobilized lipases (triacylglycerol acylhydrolase, EC 3.1.1.3), namely Novozyme NS81006 435, to flexibly produce acid ethyl esters (FAEEs) concentrated PUFAs. RESULTS first step, most the glycerides (FAGCs) were converted conversion rate...

Golden pompano Trachinotus ovatus is an important farmed carnivorous marine teleost. Although some enzymes for long-chain polyunsaturated fatty acid (LC-PUFA) biosynthesis have been identified, the ability of T. endogenous unknown. Here, we evaluated in vivo LC-PUFA synthesis a 56-day culture experiment using six diets (D1–D6) formulated with linseed and soybean oils to produce dietary linolenic/linoleic (ALA/LA) ratios ranging from 0.14 2.20. The control diet (D0) used fish oil as lipid...
