    On the need of mode interpolation for data-driven Galerkin models of a transient flow around a sphere

    We present a low-dimensional Galerkin model with state-dependent modes capturing linear and nonlinear dynamics. Departure point is a direct numerical simulation of the three-dimensional incompressible flow aro...

    Urinary angiotensinogen and urinary sodium are associated with blood pressure in normoalbuminuric children with diabetes

    The aim of this study was to evaluate the association between blood pressure (BP) and urinary angiotensinogen excretion (uAGT) and renal sodium excretion (uNa) in children with type 1 diabetes mellitus (DM1).

    Automatic Detection of Features (Markers) on a Three-Dimensional Model of a Human Face

    The post-processing and correlation analysis (like Proper Orthogonal Decomposition) requires the same topology for all objects in the database. Thus, in the case of 3D scanned data, registration is required. O...

    Normal-range albuminuria does not exclude nephropathy in diabetic children

    Clinically detectable diabetic nephropathy (DN) begins with the development of microalbuminuria (MA). However, early renal dysfunction may be overlooked despite using that method. On the other hand, the gold s...
