Increasing cones, recession cones and global cones

Optimization, 2000
In this paper, we discuss and compare various cones used in the economics literature to analyze arbitrage in general equilibrium models with short seling. Our main result is that under certain conditions on an economic model, the closure of the increasing cone and the closure of the global cone are both equal to the arbitrage cone, the recession cone ...

On Cone-Efficiency, Cone-Convexity and Cone-Compactness

SIAM Journal on Applied Mathematics, 1978
The properties of efficient (admissible) points of subsets of $R^n $ are discussed in the case when the space is ordered by a convex cone. It is demonstrated that the notion of cone-compactness (a generalization of compactness) is sufficient to guarantee the existence of an efficient point.

Cones, Dual Cones

1972
We now proceed to a systematic study of cones — sets of a special type which will play an important role in the sequel.

Dysflective Cones

2019
Retinal imaging has advanced to enable noninvasive in vivo visualization of macular photoreceptors with cellular resolution. Images of retinal structure are best interpreted in the context of visual function, but clinical measures of visual function lack resolution on the scale of individual cells.

The intrinsic normal cone

, 1996
.Let $X$ be an algebraic stack in the sense of Deligne-Mumford. We construct a purely $0$-dimensional algebraic stack over $X$ (in the sense of Artin), the intrinsic normal cone ${\frak C}_X$.

Are ‘Partial Cones’ Aberrated Cones?

AIP Conference Proceedings, 2008
‘Partial cones’ are classified as pulsars where the steepest gradient (SG) of the polarization‐position angle (PPA) traverse lies towards one edge of the pulse profile. Here we present single pulse polarimetric observations of various ‘partial cones’ observed with the Giant Meterwave Radio Telescope (GMRT) and the Arecibo Observatory(AO).

VI.—“Cone-in-Cone.”

Geological Magazine, 1885
In the June Number of the Geological Magazine an abstract is given of a paper on Cone-in-cone, read by Mr. John Young before the Geological Society of Glasgow, in which he advances the theory that this peculiar structure is caused by the escape of gases.

Maintaining Cone Function in Rod-Cone Dystrophies

2018
Retinal degenerative diseases are a major cause of untreatable blindness due to a loss of photoreceptors. Recent advances in genetics and gene therapy for inherited retinal dystrophies (IRDs) showed that therapeutic gene transfer holds a great promise for vision restoration in people with currently incurable blinding diseases.

Standing cones and lying cones

Rheologica Acta, 1971
It can be demonstrated in reconstructive surgery when using a fusiform excision that as the ratio of its lengthL to widthW is increased, the probability of a satisfactory closure is also increased. It is found that there is a minimum value ofL/W for a given area of skin beyond which small “standing cones” appear at the ends of the excision on closure ...
