Toric Representation and Positive Cone of Picard Group and Deformation Space in Mirror Symmetry of Calabi-Yau Hypersurfaces in Toric Varieties [PDF]

open access: yes, 2011
We derive the combinatorial representations of Picard group and deformation space of anti-canonical hypersurfaces of a toric variety using techniques in toric geometry. The mirror cohomology correspondence in the context of mirror symmetry is established

Cone and rod function in cone degenerations

open access: yesVision Research, 1997
Progressive cone dystrophy (CD) is usually marked in the initial stages by reduced visual acuity, color vision deficiency and alterations in the photopic electroretinogram, while morphological alterations can be very mild; in some forms rods are affected in a later stage as well.

Fano manifolds of index n-1 and the cone conjecture [PDF]

open access: yes, 2012
The Morrison-Kawamata cone conjecture predicts that the actions of the automorphism group on the effective nef cone and the pseudo-automorphism group on the effective movable cone of a klt Calabi-Yau pair $(X, \Delta)$ have finite, rational polyhedral ...

Review Essay: Resilience in Russian Immigrant Stories: An Alternative to Deficiency Models

open access: yesForum: Qualitative Social Research, 2007
At first glance, "Red Blues: Voices from the Last Wave of Immigrants" is simply a collection of immigrant stories. However, SHASHA and SHRON capture immigrant experiences from a rich array of social landscapes such as "Privilege Lost," "God and Religious

Progressive Cone-Dystrophy, Cone-Rod Dystrophy, and Rod-Cone Dystrophies

open access: yesGüncel Retina Dergisi (Current Retina Journal), 2021
Cone-rod dystrophies are retinopathies in which cones are mainly affected and rod-cone dystrophies (retinitis pigmentosa) are retinopathies in which rods are mainly affected. The most common symptoms in cone-rod dystrophies are a progressive decrease in central vision and color vision loss.

Positive solutions of a third-order three-point boundary-value problem

open access: yesElectronic Journal of Differential Equations, 2008
We obtain upper and lower estimates for positive solutions of a third-order three-point boundary-value problem. Sufficient conditions for the existence and nonexistence of positive solutions for the problem are also obtained.

Resonance in a Cone-Topped Tube

open access: yesInternational Scholastic Journal of Science, 2011
The relationship between ratio of the upper opening diameter of a cone-topped cylinder to the cylinder diameter,and the ratio of the length of the air column to resonant period was examined. Plastic cones with upper openings ranging from 1.3 cm to 3.6 cm
