Leaching of heavy metals from wood biomass ash, before and after binding in cement composite [PDF]
Journal of the Serbian Chemical Society, 2022 Wood ash is a complex mixture of inorganic and organic compounds. It is heterogeneous in composition, which can vary considerably. Ash is mainly disposed of in landfills, which creates a risk for air, soil and groundwater contamination by trace elements.

Enrichment of vitamin E in palm fatty acid distillate using sequential-cooling urea–fatty acid complexation [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2018 Sequential-cooling urea–fatty acid complexation is a novel technique developed to pre-concentrate vitamin E extracted from palm fatty acid distillate before further purification by supercritical fluid extraction. The efficacies of the sequential-cooling

Extraction Security of Sequential Aggregate Signatures [PDF]
Chinese Journal of Electronics, 2021 Aggregate signature schemes enable anyone to compress many signatures into one. Besides the unforgeability of aggregate signature, another property called aggregate extraction sometimes is useful. In sequential aggregate signature schemes, the aggregate signature is computed incrementally by the signers.

Convolutional RNN: an Enhanced Model for Extracting Features from Sequential Data [PDF]
, 2016 Traditional convolutional layers extract features from patches of data by applying a non-linearity on an affine function of the input. We propose a model that enhances this feature extraction process for the case of sequential data, by feeding patches of

Extractable information capacity in sequential measurements metrology
Physical Review Research, 2023 The conventional formulation of quantum sensing is based on the assumption that the probe is reset to its initial state after each measurement. In a very distinct approach, one can also pursue a sequential measurement scheme in which time-consuming resetting is avoided.
