Hyperbolicity cones are amenable

, 2023
Amenability is a notion of facial exposedness for convex cones that is stronger than being facially dual complete (or "nice") which is, in turn, stronger than merely being facially exposed.

Cones of potentials [PDF]

Proceedings of the American Mathematical Society, 1975
We construct a cone of potentials from a T T -monotone operator and use this to give smoothness of supersolutions solving a

Spruce Morphological Diversity in the Northern Taiga Subzone of the Arkhangelsk Region

Лесной журнал
The study of morphological diversity in woody plants is of considerable scientific and practical interest for breeding and reforestation. The relevance of this work is due to the introgressive hybridisation of European spruce (Picea abies (L.) Karst) and

Dynamics of vortex shedding from slender cones

, 2009
PhDThe dynamics of vortex shedding from bluff bodies has been investigated experimentally for many decades, with the simple geometric case for the investigation being a uniform circular cylinder aligned with its axis normal to the flow. Even though

Retinal cone photoreceptors of the deer mouse Peromyscus maniculatus : development, topography, opsin expression and spectral tuning

, 2013
A quantitative analysis of photoreceptor properties was performed in the retina of the nocturnal deer mouse, Peromyscus maniculatus, using pigmented (wildtype) and albino animals.

Intrapopulational variability of Pinus sylvestris L. from Piekielna Góra in respect to cone and needle traits

Acta Societatis Botanicorum Poloniae, 2014
From 37 Scots pine trees in Piekielna Góra the two-year old cones were collected and studied in respect to 14 morphological traits including the setting angle.

On the derivative cones of polyhedral cones [PDF]

Advances in Geometry, 2012
Abstract Hyperbolic polynomials elegantly encode a rich class of convex cones that includes polyhedral and spectrahedral cones. Hyperbolic polynomials are closed under taking polars and the corresponding cones-the derivative cones-yield relaxations for the associated optimization problem and exhibit interesting facial properties.

Variability in oil droplet numbers and proportions in the retinas of anole lizards

Frontiers in Amphibian and Reptile Science
Colored oil droplets are a common feature in the cones of almost all diurnal lizards. Using white light microscopy, three chromotypes of droplet can be identified in anoles – yellow, green and colorless. These droplets have been associated with different

Variability of eight Polish populations of Pinus sylvestris L. expressed in traits of cones

Acta Societatis Botanicorum Poloniae, 2014
Two-year old cones were collected from 257 standing Pinus sylvestris L. trees, representing 8 Polish populations of the species. The cones were analyzed in respect to 11 morphological traits.
