We study compactifications of type IIA supergravity on cosets exhibiting SU(3) structure. We establish the consistency of the truncation based on left-invariance, providing a justification for the choice of expansion forms which yields gaugedN = 2 supergravity in four dimensions. We explore N = 1 solutions of these theories, emphasizing the requirements of(More)
Spiral patterns are found to be a generic feature in close-packed elastic structures. We describe model experiments of compaction of quasi-1D sheets into quasi-2D containers that allow simultaneous quantitative measurements of mechanical forces and observation of folded configurations. Our theoretical approach shows how the interplay between elasticity and(More)
A deficient leucocyte immunological function could cause the reported high rate of lethal infections following renal transplantation in patients affected by Fabry's disease. We have studied humoral immunity, peripheral lymphocyte subsets, mitogenic lymphocyte response in vitro and granulocyte function in three patients with Fabry's disease. The(More)
Current medically relevant metals for prosthetic reconstructions enjoy a relatively good success rate, but their performance drops significantly in patients with compromised health status, and post-surgical infections still remain an important challenge. To address these problems, different nanotechnology-based strategies have been exploited to create(More)
Animal cell shape is largely determined by the cortex, a thin actin network underlying the plasma membrane in which myosin-driven stresses generate contractile tension. Tension gradients result in local contractions and drive cell deformations. Previous cortical tension regulation studies have focused on myosin motors. Here, we show that cortical actin(More)
We apply the techniques of special Kähler geometry to investigate AdS4 vacua of general N = 2 gauged supergravities underlying flux compactifications of type II theories. We formulate the scalar potential and its extremization conditions in terms of a triplet of prepotentials Px and their special Kähler covariant derivatives only, in a form that recalls the(More)
