In order to evaluate the performance of stents used in transcatheter aortic valve implantation (T-AVI), finite element simulations are set up to reconstruct patient specific contact forces between implant and its surrounding tissue. The reference geometry of the stent is obtained using micro-CT scanning data. A procedure is defined to create a numerically efficient and robust model of the stent...

We compute the cohomology of the Picard bundle on the desingularization J̃ d (Y ) of the compactified Jacobian of an irreducible nodal curve Y . We use it to compute the cohomology classes of the Brill–Noether loci in J̃ d (Y ). We show that the moduli space M of morphisms of a fixed degree from Y to a projective space has a smooth compactification. As another application of the cohomology of the...

We generalize wave maps to biwave maps. We prove that the composition of a biwave map and a totally geodesic map is a biwave map. We give examples of biwave nonwave maps. We show that if f is a biwave map into a Riemannian manifold under certain circumstance, then f is a wave map. We verify that if f is a stable biwave map into a Riemannian manifold with positive constant sectional curvature sa...

The performance of networked systems that support common human activities, such as mobile communication and participation in online games, depends on the characteristics of human mobility. Human mobility models are crucial in the design and tuning of these systems, but depend on detailed and long-term human mobility traces, which, in turn, are difficult to obtain from real environments. Thus, a...

The cortical area map is initially patterned by transcription factor (TF) gradients in the neocortical primordium, which define a "protomap" in the embryonic ventricular zone (VZ). However, mechanisms that propagate regional identity from VZ progenitors to cortical plate (CP) neurons are unknown. Here we show that the VZ, subventricular zone (SVZ), and CP contain distinct molecular maps of regi...

| Radial basis functions are presented as a practical solution to the problem of interpolating incomplete surfaces derived from three-dimensional (3-D) medical graphics. The speciic application considered is the design of cranial implants for the repair of defects, usually holes, in the skull. Radial basis functions impose few restrictions on the geometry of the interpolation centers and are su...

BACKGROUND Cultural values are invisible and relatively constant in societies. The purpose of the present study is to find diversities in cultural values of Iranian and Malaysian nursing students. MATERIALS AND METHODS Convenience sampling method was used for this comparative-descriptive study to gather the data from full-time undergraduate degree nursing students in Iran and Malaysia. The da...

We analyze Loewner traces driven by functions asymptotic to κ √ 1− t. We prove a stability result when κ 6= 4 and show that κ = 4 can lead to non locally connected hulls. As a consequence, we obtain a driving term λ(t) so that the hulls driven by κλ(t) are generated by a continuous curve for all κ > 0 with κ 6= 4 but not when κ = 4, so that the space of driving terms with continuous traces is n...
