PURPOSE To determine if primary open-angle glaucoma (POAG) patients can be differentiated from controls based on metabolic characteristics. METHODS We used ultra-high resolution mass spectrometry with C18 liquid chromatography for metabolomic analysis on frozen plasma samples from 72 POAG patients and 72 controls. Metabolome-wide Spearman correlation was performed to select differentially exp...

We present a complete processing line to enhance large Remote Sensing (RS) image databases in the framework of real-time 3D rendering. RS and Virtual Reality communities are faced to several challenges to deal in real-time with large image datasets while preserving high quality and realistic rendering. There is an increasing interest of InSAR (Interferometric Synthetic Aperture Radar) data, due...

The concept and the computation of terrain representation error (ETR) are investigated and total DEM error is presented as an accuracy index for DEM evaluation at a global level. A promising method of surface modelling based on the theorem of surfaces (SMTS) has been developed. A numerical test and a real-world example are employed to comparatively analyze the simulation accuracy of SMTS and th...

Nowadays there is a wide range of systems that provide an efficient and fast data capture for the DEM generation and the spread of the computer systems has allowed the use of DEM to a high number of technicians. Unfortunately, the DEM analysis tools do not have similar development. Actually, the analyses are mainly based in the application of local scale operators that provide additional inform...

The shoot and root apical meristems (SAMs and RAMs, respectively) of higher plants are mechanistically and structurally similar. This has led previously to the suggestion that the SAM and RAM represent modifications of a fundamentally homologous plan of organization. Despite recent interest in plant development, especially in the areas of meristem regulation, genes specifically required for the...
