Purpose. To evaluate the relationship between macular microstructures and visual function in retinitis pigmentosa (RP). Method. Fourier domain optical coherence tomography (FD-OCT) and Goldmann perimetry were used to examine 100 eyes of 100 RP patients. The preserved photoreceptor outer segment (PROS) length was measured at the horizontal and vertical high definition line scans. The PROS area w...

In this paper, I have explored a significant concept for the miniaturization of microstrip patch antenna configuration by using the double negative (DNG) left-handed Metamaterials, which have dielectric permittivity and magnetic permeability both negative, simultaneously. It is achieved through the concept of phase-compensation by thin slab consist of the double positive (DPS) material, which h...

The Break-Off method is the most recent development in in-place concrete strength testing. In this method, the force required to break-off an in-place concrete cylinder 2.17 in. (55 mm) in diameter and 2-2/4 in. (70 mm) long, is related to the compressive strength of the concrete from a predetermined calibration curve developed for this concrete mix. The reliability of the BreakOff method to te...

This article studies the transient heat conduction in a slab when passing through various sections of the furnace, and focuses on the thickness of the scale layer formed on the slab. The transient heat conduction behavior of a slab in various sections of the heating furnace is analyzed using the Laplace transformation method, including the pre-heating zone, the first heating zone, the second he...

An analytic approach combining the effect of equilibrium diamagnetic flows and the finite ion-sound gyroradius associated with electron-ion decoupling and kinetic Alfvén wave effects is derived to study resistive drift instabilities in a plasma slab. Linear numerical computations using the NIMROD code are performed with cold ions and hot electrons in a plasma slab with a doubly periodic box bou...

[1] Global observations of electron density profiles from the COSMIC satellites are used to investigate, for the first time, the altitudinal dependence of the ionospheric response to the recurrent geomagnetic activity at different latitudinal regions during the extreme solar minimum period of 2008. Our results show that the 9-day oscillations in NmF2 are out of phase with those in Kp at high la...

In Figure S1, the computed surface energies obtained with slab models of increasing number of O-Ti-O layers are plotted. We compare the values obtained by keeping all the coordinates fixed in the bulk positions (black symbols in the figure) to those obtained by relaxing the outermost layers of the slab (green for 1 layer and red for two layers), and keeping fixed at bulk coordinates the innermo...

This paper investigates the characteristics of surface waves propagating on a grounded anisotropic dielectric slab. Distinct from the existing analyses that generally assume that the fields of surface wave uniformly distribute along the transverse direction of the infinitely large grounded slab, our method takes into account the field variations along the transverse direction of a finite-width ...

The theoretical model to compute the long-term stress of simply supported steel-concrete composite beam was deduced. The model includes the effects of steel bars in concrete slab, concrete shrinkage and creep. The computed results agreed well with the test results. On this basis, the effects of factors such as concrete age to loading, longitudinal reinforcement ratio in concrete slab, concrete ...

This paper presents a comprehensive numerical and theoretical investigation into the flexural capacities of composite joints with reinforced concrete (RC) slab. The improved 3D (three-dimensional) models were established by MSC. Marc (2012) calibrated experimental observations presented in companion (Mou et al., 2019a [1]). Supplementary parametric studies then undertaken to examine effect slab...
