Getting Double Crossed.
Keratoconus is a non-inflammatory corneal dystrophy in which the cornea deforms due to thinning and protrusion. The biomechanical strength of the cornea depends on the lamellar organization of the collagen fibers that comprise the corneal stroma, regulated by an interconnecting network of proteoglycans. Although the pathogenesis of keratoconus remains unclear, it appears that a primary event le...
متن کاملDouble-crossed chords and distance-hereditary graphs
An early characterization of distance-hereditary graphs is that every cycle of length 5 or more has crossing chords. A new, stronger, property is that in every cycle of length 5 or more, some chord has at least two crossing chords. This new property can be characterized by every block being complete multipartite, and also by the vertex sets of cycles of length 5 or more always inducing 3-connec...
متن کاملDouble Construction for Crossed Hopf Coalgebras
Recently, Turaev [19, 20] (see also Le and Turaev [8] and Virelizier [23]) generalized the notion of a TQFT and Reshetikhin-Turaev invariants to the case of 3-manifolds endowed with a homotopy classes of maps to K(π, 1), where π is a group. One of the key points in [19] is the notion of a crossed Hopf π-coalgebra, here called a Turaev coalgebra or, briefly, a T-coalgebra (see Section 1). As one...
متن کاملTransceiver double crossed saddle for rodents at 2T
Introduction: Small animal MR imaging and spectroscopy, where spatial resolution is a limiting factor, requires the use of distinct transmit and receive coils [1]. This approach makes easier the optimization of the RF field homogeneity for transmit-only coils and signal-to-noise ratio (SNR) for receive-only coils. It also requires that RF coils should be electrically decoupled, commonly using P...
متن کاملArginine and arginase: endothelial NO synthase double crossed?
In a remarkable article published in this issue of Circulation Research, Ryoo et al1 propose endothelial arginase II as a novel target for the treatment of atherosclerosis. Actually, they already had done so 2 years ago, based on work mainly on cultured human aortic endothelial cells,2 which indeed appeared to provide an unexpected way to explain endothelial dysfunction in terms of NO productio...
