Innamorati and Zuanni [J. Geom. 111 (3), 2020] have provided a combinatorial characterization of Baer unital cones in $PG(3,q)$. The current paper generalizes these results to arbitrary dimension. Furthermore, are extended hyperoval maximal arc cones.

Microspectrophotometry was used to measure the visual pigments in the rods and cones of 22 species of marine fish larvae netted from the surface waters off Friday Harbor Laboratories, Washington, USA. 13 species had rods, 12 of which contained visual pigments with a wavelength of maximum absorbance near 500 nm, while one, the sand lance (Ammodytes hexapterus), had its absorbance maximum at 482 ...

In addition to their involvement in transsynaptic communication in the adult nervous system, neurotransmitters also participate in many developmental events, such as neurite initiation and outgrowth. Although growth cones can release transmitters and are themselves sensitive to exogenously applied neurotransmitters, a direct causal relationship between the release of transmitter from one growth...

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...

We study some relations between a reproducing cone K in a linear space V over a fully ordered field F and the cone I(K) in Hom( V, V) consisting of all operators A such that AK G K. In particular, indecomposable cones are considered.

In this paper we study a class of convex sets which are called closed pseudo-cones and new duality class. It turns out that the characterizes is essentially only possible abstract them.The characterization corresponding to classification endomorphisms pseudo-cones.

Abstract We relate quantum degree cones, parametrizing PBW degenerations of quantized enveloping algebras, to (negative tight monomial) cones introduced by Lusztig in the study monomials canonical bases, K -theoretic for quiver representations, and some maximal prime tropical flag varieties.

A characterization of algebraic cones in terms of actions of the onedimensional multiplicative algebraic monoid Mm and the algebraic group Gm are given. This note answers a question of K. Adjamagbo asked in [A]. Below all algebraic varieties are taken over an algebraically closed field k. An irreducible algebraic variety X is called a cone if X is affine and its coordinate algebra k[X ] admits ...

introduction: gutta-percha is the most commonly used material for root canal obturation; it has been recently manufactured with different tapers. the aim of this in vitro study was to compare microleakage of canals obturated with standard gutta-percha (0.02 taper) or the new 0.04 taper gutta-percha master cone using the cold lateral condensation technique. materials and methods: forty-four extr...

Microspectrophotometric measurements have been obtained for individual receptors from the enucleated eye of a known deuteranope. In a sample of 17 receptors we recorded 5 rods, 2 short-wave cones and 10 long-wave cones but no middle-wave cones. The results are concordant with psychophysical results for the patient's remaining eye.
