In RoboCup Standard Platform League (SPL), the method using unscented particle filter (UPF) has been proposed for self-localization. The UPF resolves a problem of particle filter which cannot be sampled appropriately when the likelihood is too high or low. This filter can estimate accurate position when...

In this work we apply the Weiss, Tabor and Carnevale integrability criterion (Painlevé analysis) to the classical version of the two dimensional Bukhvostov-Lipatov model. We are led to the conclusion that the model is not integrable classically, except at a trivial point where the theory can be described...

Symmetry properties of some Fokker-Planck equations are studied. In the one-dimensional case, when symmetry groups turn out to be six-parameter ones, this allows to find changes of variables to reduce such Fokker-Planck equations to the one-dimensional heat equation. The symmetry and the family of exact...

The estimation of cost and production functions in economics relies on standard specifications which are less than satisfactory in numerous situations. However, instead of fitting the data with a pre-specified model, Artificial Neural Networks (ANNs) let the data itself serve as evidence to support the...

Although the clinical relevance of arterial stiffness is increasingly recognized, the applicability of arterial stiffness for individual cardiovascular risk assessment is hampered due to technical and physiological difficulties. Arterial stiffness is not constant with blood pressure and not constant...

Stiffening of central conduit arteries –areas where the mechanoreceptors are embedded (e.g., ascending aorta and carotid artery) – is considered to be associated with the impaired baroreflex control in response to hypotensive stress. Arterial stiffness is modulated by vascular tone transiently and dynamically,...

An incomplete uncertain preference relation (UPR) is typical in group decision making (GDM) for decision makers (DMs) to express preference over alternatives because of the information interaction barrier between people and decision making environment. Completing missing values can guarantee individual...

Methods: We studied 1157 subjects from the HARVEST study (mean follow-up 5.9...

Objectives: Hypertension is associated with increased arterial stiffness, which is an independent predictor of cardiovascular risk. Aortic systolic blood pressure (SBP) and/or pulse pressure (PP) better predicts cardiovascular events than peripheral blood pressure. The present study compared the discriminative...

Subjects of African and African-Caribbean ethnicity have been reported to have lower plasma renin activity (PRA), decreased endothelium-dependent vasomotor function and increased intima-media thickening relative to white European subjects. We explored whether vascular structure and function might be...

Background: Hypertension exacerbates cardiovascular disease in type 2 diabetes (T2DM) but the ACCORD trial suggested limited impact on CVS events by hypertensive treatment. Our hypothesis is that arterial stiffness, measured as aortic pulse wave velocity (PWV) may underlie these events. Few data exist...
