Integration of multiple range and intensity image pairs using a volumetric method to create textured three-dimensional models

2001

We present a volumetric approach to three-dimensional (3D) object modeling that differs from previous techniques in that both object texture and geometry are considered in the reconstruc- tion process. The motivation for the research is the simulation of a thermal tire inspection station. Integrating 3D geometry information with two-dimensional thermal images permits the thermal informa- tion to be displayed as a texture map on the tire structure, enhanc- ing analysis capabilities. Additionally, constructing the tire geometry during the inspection process allows the tire to be examined for structural defects that might be missed if the thermal data were textured onto a predefined model.

Towards interpretable classifiers with blind signal separation

2012

Blind signal separation (BSS) is a powerful tool to open-up complex signals into component sources that are often interpretable. However, BSS methods are generally unsupervised, therefore the assignment of class membership from the elements of the mixing matrix may be sub-optimal. This paper proposes a three-stage approach using Fisher information metric to define a natural metric for the data, from which a Euclidean approximation can then be used to drive BSS. Results with synthetic data models of real-world high-dimensional data show that the classification accuracy of the method is good for challenging problems, while retaining interpretability.

Lesions to the posterior insular cortex cause dysarthria

2011

Background:  Up to now, there are few systematic studies in a sufficient number of patients with lesions involving the insular cortex (IC) examining whether damage of the IC is directly related to dysarthria. Thus, this is the first study applying modern voxel-lesion behaviour mapping (VLBM) aimed to examine whether the IC is involved in dysarthria – and if so – which part of the IC is involved. Methods:  Twenty-five patients with acute stroke lesions affecting the IC and peri-insular region were investigated employing VLBM analysis. Results:  Present data indicated that dysarthria is associated with stroke lesions affecting the right- and left-sided posterior IC. Conclusions:  Owing to the…

Response to Anti CD20 Monoclonal Antibody Rituximab® and Epitope Mapping of Inhibitory Antibodies in Patients with Acquired Haemophilia.

2006

Abstract Introduction: Acquired haemophilia (AcH) is associated with the development of polyclonal autoantibodies against FVIII, which affect directly the A2 or C2 domain of the FVIII molecule. Immunomodulatory therapy regimes to normalize FVIII levels and to eliminate the inhibitor are essential options in the treatment of patients (pts) with AcH. The aims of the present study were to investigate the response to Rituximab® and to localize the inhibitor epitopes on the FVIII domains. Patients and Methods: In 5 pts with AcH (2 females,3 males; age: 64–81 yrs) the inhibitor titers ranged from 9 to 156 BU and the FVIII activities from <1 % to 6 %. Rituximab® was administered once weekly…

Pheromone-induced odor learning modifies Fos expression in the newborn rabbit brain.

2013

Research report; International audience; Associative learning contributes crucially to adjust the behavior of neonates to the permanently changing environment. In the European rabbit, the mammary pheromone (MP) excreted in milk triggers sucking behavior in newborns, and additionally promotes very rapid learning of initially neutral odor cues. Such stimuli become then as active as the MP itself to elicit the orocephalic motor responses involved in suckling. In this context, the rabbit is an interesting model to address the question of brain circuits early engaged by learning and memory. Here, we evaluated the brain activation (olfactory bulb and central regions) induced in 4-day-old pups by …

Sharpness of the differentiability almost everywhere and capacitary estimates for Sobolev mappings

2017

We give sharp conformal conditions for the dfferentiability in the Sobolev space W1, n-1 loc (Ω,Rn). Furthermore, we show that the space W1, n-1 loc (Ω,Rn) can be considered as the borderline space for some capacitary inequalities. peerReviewed

Dal CAD al GIS: il trasferimento di informazioni cartografiche

2005

L’utilizzo della cartografia nei GIS impone una riflessione sulle caratteristiche che essa deve possedere al fine di consentire le elaborazioni tipiche di questi sistemi e rende necessario verificare quali siano le informazioni che rimangono associate agli oggetti della classe al momento del caricamento dei dati, in formato DXF, all’interno di software GIS. Negli ultimi anni a livello internazionale sono state fissate norme tendenti a individuare linee guida per la definizione della struttura del contenuto semantico della cartografia numerica, delle caratteristiche geometriche e delle relazioni topologiche dell’informazione geografica.

Peptide mapping by reversed-phase high-performance liquid chromatography employing silica rod monoliths.

2003

In this paper, a general procedure is described for the generation of peptide maps of proteins with monolithic silica-based columns. The peptide fragments were obtained by tryptic digestion of various cytochrome c species with purification of the tryptic fragments achieved by reversed-phase high-performance liquid chromatographic methods. Peak assignment of the various peptides was based on evaluation of the biophysical properties of the individual peptides and via mass spectrometric identification. The performance of several different monolithic sorbents prepared as columns of identical cross-sectional dimensions were investigated as part of these peptide mapping studies and the data evalu…

Differential function of the phosphoglucomutase isozymes PGM1 and PGM2

1979

A total of 13 metabolites thought to be possibly inhibitory were tested for their influence on PGM isozyme activities, each at several different concentrations. The analysis of statistical significance was based on enzyme activities obtained by densitometric measurements of starch gels. Five of the substances were found to inhibit PGM activity, three of which definitely and a further one probably led to a significantly stronger inhibition of the isozymes of the PGM2 locus than of PGM1 isozymes. They are (1) fructose-1,6-diphosphate, (2) adenosine triphosphate, (3) citrate, and (4) possibly 2,3-diphosphoglycerate. Thus, PGM1 isozymes proved to function better in hard or perhaps marginal meta…
