Coherence in the Ferroelectric AClO (A = Li, Na) Family of Electrolytes.

Coherence is a major caveat in quantum computing. While phonons and electrons are weakly coupled in a glass, topological insulators strongly depend on the electron-phonon coupling. Knowledge of the electron-phonon interaction at conducting surfaces is relevant from a fundamental point of view as well as for various applications, such as two-dimensional and quasi-1D superconductivity in nanotechnology.

Studying Enhanced Recovery After Surgery (ERAS®) Core Items in Colorectal Surgery: A Causal Model with Latent Variables.

Background: Previous Enhanced Recovery After Surgery (ERAS®) studies have not always taken into account that ERAS interventions depend on baseline covariates and that several confounding variables affect the composite outcomes.

Method: A causal latent variable model is proposed to analyze data obtained prospectively concerning 1261 patients undergoing elective colorectal surgery within the ERAS protocol. Primary outcomes (composite of any complication, surgical site infection, medical complications, early ready for discharge (TRD), early actual discharge) and secondary outcomes (composite of late bowel function recovery, IV fluid resumption, nasogastric tube replacement, postoperative nausea and vomiting, re-intervention, re-admission, death) are considered along with their multiple dimensions.

Biocompounds recovery from olive mill wastewater by liquid-liquid extraction and integration with Fenton's process for water reuse.

The olive mill wastewaters obtained from two different processes, press extraction olive mill wastewater (POMW) from Portugal and two-phase system olive mill wastewater (2POMW) from Spain, were treated to recover phenolic compounds and water sequentially, by the integration of liquid-liquid extraction with Fenton's processes. From the recovered fractions, squalene, oleic acid, tyrosol, syringic acid, and p-coumaric acid were identified, and oleic acid appears in a higher concentration for 2POMW wastewater for all used solvents compared to POMW samples. Recovered fractions presented higher antioxidant activity, but remained antioxidants were found in the residual water.
