Preparation, Characterization and Application of Ultrathick True Zero-Order KDP Crystal Waveplates

IEEE Access, 2019
In crystal space, the birefringence varies continuously with respect to the propagating direction of the light wave. By utilizing this property, we design and fabricate a series of ultrathick true zero-order (TZ) waveplates based on KH2PO4 crystals with ...

The thick and thin of the central corneal thickness in glaucoma [PDF]

Eye, 2018
Central corneal thickness (CCT) is an important parameter in the assessment of any potential glaucoma patient. While it affects prognosis in ocular hypertension, its value in patients diagnosed with glaucoma is less certain. There are several biological factors and genetic components that may influence glaucoma progression, which have been associated ...

Separating Thickness from Geometric Thickness [PDF]

, 2002
We show that graph-theoretic thickness and geometric thickness are not asymptotically equivalent: for every t, there exists a graph with thickness three and geometric thickness >= t.

Single nucleotide polymorphism in the neuroplastin locus associates with cortical thickness and intellectual ability in adolescents [PDF]

, 2015
Despite the recognition that cortical thickness is heritable and correlates with intellectual ability in children and adolescents, the genes contributing to individual differences in these traits remain unknown.
