Journal of the Association for Information Science and Technology, EarlyView.Abstract Aspect‐Based Sentiment Analysis (ABSA) has evolved from textual analysis to a multimodal paradigm, integrating visual information to capture nuanced sentiments. Despite advancements, existing Multimodal ABSA (MABSA) research remains limited in granularity, which focuses on either coarse‐level categories or named entities, neglecting fine ...

Using geostatistical methods for evaluating organic matter reserves in fallow soils
Учёные записки Казанского университета: Серия Естественные науки, 2019 In the samples taken layer by layer (every 5 cm) from the old arable horizon of fallow light gray forest soils, the content of organic matter and the bulk density were determined in order to calculate humus reserves.

Chemical composition of the humus layer, mineral soil and soil solution of 200 forest stands in the Netherlands in 1995 [PDF]
A nationwide assessment of the chemical composition of the soil solid phase and the soil solution in the humus layer and two mineral layers (0-10 cm and 10-30 cm) was made for 200 forest stands in the year 1995.

Cereal Chemistry, EarlyView.ABSTRACT Background There is an increasing interest in healthier, nutrient‐rich foods so alternative grains produced in smaller quantities—including spelt wheat (Triticum spelta L.)—have once again become the focus of consumers. At the same time, the scientific proof of these claims is incomplete.

Carbon Energy, EarlyView.This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...

An appraisal of nutrient supplies available for tree growth in a pumice soil [PDF]
, 1970 Chemical analyses have confirmed and explained the results of an earlier pot trial in which the availability of major nutrients in six pumice ash layers of Kaingaroa silty sand was assessed by the growth of radiata pine seedlings. Almost all of the tree-

Chemistry – A European Journal, EarlyView.Crystal phase‐ and size‐selective synthesis of chalcopyrite and wurtzite‐type CuGaS2 NPs was successfully achieved. They exhibited clear LSPR in the NIR region. The extinction coefficient of chalcopyrite was three times higher than that of wurtzite due to its greater symmetry and dipole moment. These results will enable precise control of the plasmonic
