PURPOSE Geometric morphometrics (GM) was used to analyze the shape of the peripapillary retinal pigment epithelium-Bruch's membrane (RPE/BM) layer imaged on the SD-OCT 5-line raster in normal subjects and in patients with papilledema and ischemic optic neuropathy. METHODS Three groups of subjects were compared: 30 normals, 20 with anterior ischemic optic neuropathy (AION), and 25 with papille...

In this work, a reduced order model is constructed for a hydraulic mixing nozzle using proper orthogonal decomposition. Data from several CFD computations are collected to provide the data for input to the reduced order model and flow is projected onto the most dominant principal axes to study the flow structures. Flow structures are compared for the original and optimized shape nozzles to stud...

A new U-shape panda polarization-maintaining fiber (PPMF) based microfiber interferometer coated with graphene oxide (GO) film was proposed and experimentally demonstrated for relative humidity (RH) sensing. Experimental results show that the sensor has refractive index (RI) sensitivity of 1692.5 nm/RIU in RI range 1.33 when diameter taper waist is 10.08 μm. The surface then modified chemically...

We enumerate possible topologies of pseudoknots in single-stranded RNA molecules. We use a steepest-descent approximation in the large N matrix field theory, and a Feynman diagram formalism to describe the resulting pseudoknot structure. An RNA molecule is a heteropolymer strand made up of four types of nucleotides, uracil (U), adenine (A), guanine (G), and cytosine (C). The sequence of these n...

This study investigates the relationship between salaries and scholastic aptitude for fulltime public high school humanities and mathematics/sciences teachers. For identification, we rely on variation in salaries between adjacent school districts within the same state. The results indicate that teacher aptitude is positively correlated with teacher salaries with an elasticity point estimate of ...

Several recent papers propose competing theoretical explanations for the empirical observation of an inverted U-shape relationship between enviromental degradation and per-capita income. We proprose the following test of the theory: calibrate a theoretical model to an already developed economy using information unrelated to the pollution-income curve. Then simulate the model starting from a les...

Studies on innovation have yielded contradictory results regarding the influence of family control, giving rise to competing perspectives that either emphasize stewardship role managers or agency problems their presence creates. Recent research integrates both perspectives, theorizing an inverted U-shaped relationship between control and innovativeness. However, scholars typically focus agenda,...
