In this paper we show how to lift Lagrangian immersions in $\mathbb{C} P^{n-1}$ produce cones ^n$, and use process several families of examples special cones. Moreover cones, isotopic the Harvey-Lawson trivial whose projections are with few transverse double points.

Abnormal' cones found irt Cupressus sempervirens include bisexual cones and double female and male cones. They are very infrequent, but there are individual trees ~th a tendency· to produce· ~\Jch cones. We, suggest that these cones reflect changes in normal hohnonal balance. keY, words: Cupressus sempervirens, bisexilal con~s, cones.

We purpose here to analyze and compare the population and topography of cone photoreceptors in two mouse strains using automated routines, and to design a method of retinal sampling for their accurate manual quantification. In whole-mounted retinas from pigmented C57/BL6 and albino Swiss mice, the longwave-sensitive (L) and the shortwave-sensitive (S) opsins were immunodetected to analyze the p...

Two articles in this issue of Environmental Health Perspectives—by Xia et al. (2013) and Bonner et al. (2013)—report results of a unique col-laborative approach to environmental health research. The consortium behind these studies (the Nano GO Consortium), which is developing standardized methods for assessing the health and safety implications of engineered nano materials (ENMs), represents a ...

introduction: the purpose of this study was to evaluate the morphologic surface of gutta­percha cones after cutting with different methods. materials and methods: the apical 3 millimeters of forty standardized, gutta-percha cones size 40 were cut off using scissors or a scalpel against a glass slab. the samples were then examined under scanning electron microscopy (sem) for topographic deformit...

Say that a cone is a commutative monoid that is in addition conical, i.e., satisfies x+y=0 ⇒ x=y=0. We show that cones (resp. simple cones) of many kinds order-embed or even embed unitarily into refinement cones (resp. simple refinement cones) of the same kind, satisfying in addition various divisibility conditions. We do this in particular for all cones, or for all separative cones, or for all...

in this paper, using clarke’s generalized directional derivative and di-invexity we introduce new concepts of nonsmooth k-α-di-invex and generalized type i univex functions over cones for a nonsmooth vector optimization problem with cone constraints. we obtain some sufficient optimality conditions and mond-weir type duality results under the foresaid generalized invexity and type i cone-univexi...
