Elman Network in Kappa Number Prediction

IFAC Proceedings Volumes, 2009
Abstract Abstract Variations in the pulp quality are mainly due to variations in the quality of wood chips used for pulping. Moisture content of chips, chip size and chip composition vary, and the measurements to reflect these variations do not always exist.

Evaluating the Pulpability and Paper Performance of Soda and Soda-Anthraquinone Pulping of Acacia Mearnsii

Journal of Natural Fibers
This study examines the pulpability of A. mearnsii grown in Ethiopia to manufacture soda and soda-anthraquinone (AQ) pulp and paper under various pulping conditions. Pulping was performed at active alkali concentrations ranging from 15 to 25%.

Effects of washing method on the bagasse pulping characteristics by Sulfur Dioxide- Ethanol-Water (SEW) process [PDF]

Iranian Journal of Wood and Paper Industries, 2017
SO2-ethanol-water (SEW) pulping can be considered a hybrid between solvent and acid sulfite pulping processes. Recently this process in order to separation the principal components (cellulose, hemicelluloses and lignin) have been considered.

The number of L_{infty,kappa}-equivalent non-isomorphic models for kappa weakly compact

, 1999
For a cardinal kappa and a model M of cardinality kappa let No(M) denote the number of non-isomorphic models of cardinality kappa which are L_{infty,kappa}--equivalent to M. In [Sh:133] Shelah established that when kappa is a weakly compact cardinal and mu<=kappa is a nonzero cardinal, there exists a model M of cardinality kappa with No(M)=mu.

Admixture Mapping Reveals Candidate Regions for Methotrexate Neurotoxicity Susceptibility: A Reducing Disparities in Acute Leukemia Consortium Report

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Neurotoxicity is a rare, often dose‐limiting adverse effect of methotrexate (MTX) therapy that disproportionally affects Latino children. Factors contributing to the observed disparity are not well understood. This study leveraged admixture mapping to identify genetic regions associated with MTX‐related neurotoxicity susceptibility ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
