Ab initio determination of the roto-torsional energy levels of hydrogen peroxide

Description: In the present paper, the roto-torsional energy levels of hydrogen peroxide are determined from ab initio calculations performed at the MP4(SDQ)/AUG-cc-pVTZ∥MP4(SDQ)/cc-pVTZ level. The rotational levels corresponding to the torsional states n = 0 and 1 are determined variationally up to J = 20. The ...

The role of large-scale spatial patterns in the chaotic amplification of perturbations in a Lorenz’96 model

Description: 13 páginas, 9 figuras.-- El Pdf del artículo es la versión post-print. , The preparation of perturbed initial conditions to initialize an ensemble of numerical weather forecasts is a crucial task in current ensemble prediction systems (EPSs). Perturbations are added in the places where they are expecte...

A comparative analysis of the QCISD(T) and the CCSD(T) potential energy surfaces for the torsional mode of glyoxal (COH-COH)

Description: In the present paper, the potential energy surface for the torsional V7 mode of glyoxal is determined by using different levels of ab initio calculations and relaxed nuclear models. Results obtained with the Quadratic Configuration Interaction (QCISD(T)) and the Couple Cluster (CCSD(T)) theories are...

Evaluation of periodic breathing in respiratory flow signal of elderly patients using SVM and linear discriminant analysis

Description: Aging population is a major concern that is reflected in the increase of chronic diseases. Heart Failure (HF) is one of the most common chronic diseases of elderly people that is punctuated with acute episodes, which result in hospitalization. The periodic modulation of the amplitude of the breathin...

Future trends of snowfall days in northern Spain from ENSEMBLES regional climate projections

Description: In a previous study Pons et al. (Clim Res 54(3):197–207, 2010. doi:10.3354/cr01117g) reported a significant decreasing trend of snowfall occurrence in the Northern Iberian Peninsula since the mid 70s. The study was based on observations of annual snowfall frequency (measured as the annual number of ...

Update of the Spain02 gridded observational dataset for EURO-CORDEX evaluation: assessing the effect of the interpolation methodology

Description: Observational gridded products are commonly used to evaluate the performance of regional climate models. To this aim, gridded datasets should be comparable to the output of these models and, thus, should represent grid-cell area-averaged values and, whenever possible, they should be defined on the s...

How well do CMIP5 Earth System Models simulate present climate conditions in Europe and Africa?

Description: This study provides a comprehensive evaluation of seven Earth System Models (ESMs) from the Coupled Model Intercomparison Project Phase 5 in present climate conditions from a downscaling perspective, taking into account the requirements of both statistical and dynamical approaches. ECMWF's ERA-Inter...
