INTRODUCTION Pre-clinical markers of Parkinson's Disease (PD) are needed, and to be relevant in pre-clinical disease, they should be quantifiably abnormal in early disease as well. Handwriting is impaired early in PD and can be evaluated using computerized analysis of drawn spirals, capturing kinematic, dynamic, and spatial abnormalities and calculating indices that quantify motor performance a...

The marine silverside (Odontesthes argentinensis) is an euryhaline species, distributed along the southwest coast of Atlantic Ocean, present in estuaries, brackish coastal lagoons and shallow waters. It a significant economic resource for local fisheries southern Brazil, Uruguay Argentina. aim this work was to contribute knowledge on stock spatial structure silverside, using otolith shape analy...

Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine metabolic disorders of reproductive age women. The main signs of PCOS are as follows: androgen excess, menstrual dysfunction, infertility, obesity, and other numerous health problems. By different authors, the disorder affects 2-28% of reproductive age women. Materials and Methods: Polycystic ovary syndrome is char...

Parallel manipulators have various advantages over serial robots but they have a few drawbacks mainly referring to stiffness and singularities. Close to or in singular configurations the structure can not resist an external wrench applied to the mobile platform, therefore it may have uncontrolled movements. The study of the stiffness becomes of primary importance to design multibody robotic sys...

A deep infrared observation of the quasar 3C 273 and its jet is presented. The K image (λ = 2.1µm) resolves the jet into single knots and for the first time detects the infrared counterpart to the radio hot spot. On the basis of the K flux densities derived for these components the run of the radio to IR and IR to optical spectral indices along the jet axis is discussed. Along the main body of ...

This study compares the quality of extrudates made from corn grits with the addition of up to 8% of spirulina powder. The sensory properties (shape, color, aroma, taste and crispness), chemicals (content of water, protein, fat, ash, fiber, carbohydrates, carotenoids, chlorophyll and phycocyanin) and physical properties (color, water absorption index, expansion indices, texture and water sorptio...

The paper reviews various topics in shape analysis. In particular, matching configurations using regression is emphasized. Connections with general shape spaces and shape distances are discussed. Kendall’s shape space and the affine shape space are considered in particular detail. Matching two configurations and the extension to generalized matching are illustrated with applications in electrop...

Differences between image processing and other disciplines in the definition and the role of shape are explored. Diverse approaches to quantifying shape are reviewed. Attention is drawn to the need for close coupling between image acquisition and shape analysis. An example of the effect of the means of observation on dynamic shape extraction is drawn from linguistics. Current instrumentation fo...

OBJECTIVES Our study aimed to distinguish the ability of anthropometric indices to assess the risk of metabolic syndrome (MetS). DESIGN Prospective cohort study. SETTING Shenyang, China. PARTICIPANTS A total of 379 residents aged between 40 and 65 were enrolled. 253 of them were free of MetS and had been followed up for 4.5 years. METHODS At baseline, all the participants underwent a th...

Motions of virtual characters in movies or video games are typically generated by recording actors using motion capturing methods. Animations generated this way often need postprocessing, such as improving the periodicity of cyclic animations or generating entirely new motions by interpolation of existing ones. Furthermore, search and classification of recorded motions becomes more and more imp...
