Abstract

The dynamical behaviour of complex quantum systems can be harnessed for information processing. With this aim, quantum reservoir computing (QRC) with Ising spin networks was recently introduced as a quantum version of classical reservoir computing. In turn, reservoir computing is a neuro-inspired machine learning technique that consists in exploiting dynamical systems to solve nonlinear and temporal tasks. We characterize the performance of the spin-based QRC model with the Information Processing Capacity (IPC), which allows to quantify the computational capabilities of a dynamical system beyond specific tasks. The influence on the IPC of the input injection frequency, time multiplexing, and different measured observables encompassing local spin measurements as well as correlations, is addressed. We find conditions for an optimum input driving and provide different alternatives for the choice of the output variables used for the readout. This work establishes a clear picture of the computational capabilities of a quantum network of spins for reservoir computing. Our results pave the way to future research on QRC both from the theoretical and experimental points of view., Comment: 12 pages, 9 figures. To be published in Cognitive Computation

Abstract

The chemical composition of essential oils of Thymus arundanus Wilk, and its parents T. mastichina L.;T. baeticus Bois ex Lacaita were determined by GC, GC/MS and IR. The major components of T. mastichina oil were 1,8-cineole (42.6%), and linalool (32.8%), while those of T. baeticus were trans-sabinene hydrate (18.2%), borneol (13.7%) and verbenone (7.3%). The major oil components of T. arundanus were similar to those found in its parents 1,8-cineole (46.4%), linalool (11.7%), trans-sabinene hydrate (3.3%), borneol (1.8%) and verbenone (1.1%), but its chemotype is closer to T. mastichina.

45. Linking dissolved organic matter composition to metal bioavailability in agricultural soils: effect of anionic surfactants.

Abstract

The bioavailability of metals in soil is only partially explained by their partition among the solid and aqueous phase and is more related to the characterization of their speciation in the soil solution. The organic ligands in solution that largely determine metal speciation involve complex mixtures and the characterization of fluorescence components of dissolved organic matter (DOM) can identify pools of molecules that participate in metal speciation, this being essential for risk assessment. The bioavailability of Cd, Cu, Pb and Zn in three agricultural soils was examined in the laboratory to recreate irrigation with greywater enriched in anionic surfactants (Aerosol 22 and Biopower). Field capacity and saturation regimes were considered for this study. Irrigation with aqueous solutions of the anionic surfactants increased total DOM concentrations and metals in the soil solution (Pb > Cu > Zn > Cd). Significant correlation (p < 0.05) between the readily available pool of metals with the concentration of DOM was determined for Cu (r = 0.67), Pb (r = 0.82) and Zn (r = 0.68). However, speciation analysis performed with the software WHAM indicated that mobilisation of DOM and metals into the soluble phase resulted in a low concentration of free ion activities and promoted the formation of metal-organo complexes. The characterization of fluorescence components revealed that DOM in soil solution from soils irrigated with Aerosol 22 was enriched in a reduced quinone-like and a humic-like component. Besides, fluorescence quenching provided further evidence of metal complexation with organic ligands in solution. Hence, metal mobilization in soil irrigated with surfactant enriched greywater occurs with solubilisation of high affinity organic ligands, which substantially decreases the potential risk of metal toxicity.

46. La mineralización de Baritina de Purroy (Zaragoza, España)

Author

Osacar Soriano, M. C., Besteiro Rafales, Josefina, and Pocoví Juan, A.

Abstract

The barite mineralization of Purroy (Zaragoza) is located in the Ordovician slates and sandstones, in the Structural Zone of Morata, the northern part of Unidad de Herrera (Eastern Iberian Chain). It is mainly composed of barite, quartz, goethite and hematite; fluorite and pirite with quartz and some Co-ore alteration minerals have also been recognized nearby. Although there is some filling-cavities barite, it occurs mainly in NllOE veins, with an evident structural control; they present features of contemporaneous mechanical deformation, related to prealpine distensive events. Barite occurs in a wide variety of aspects, very likely depending on the deposit conditions, and they bring out that at least some veins were filled in several stages, related with deformation events. Sr analysis in a cm scale shows an increase of Sr-content during the course of deposition; in a vein scale this pattern is alterated by mecanic deformations, disolutions and reprecipitations, related with a polyphasic deposit process. Analysis of trace elements suggest a geochemical influence of the environment on the formation of the barite deposit. Fe, Co & Mn are the most characteristic trace elements in this barite mineralization, and their patterns are partialy linked to barite precipitation conditions.

50. A novel photonics approach to unconventional information processing.

Author

Soriano, M. C., Brunner, D., Ortin, S., Mirasso, C. R., Larger, L., Fischer, I., and Pesquera, L.

Abstract

We present a novel scheme in which photonic information processing can be performed using a photonic system with delayed feedback. Inspired by the way our brain process information, we show that a single optoelectronic oscillator with delay can replace a complex network of nonlinear dynamical elements without losing performance.
