The balance of the mineral nutrition in mango leaves during flowering period affects trees and fruit production. Because soil karst areas has a slow unbalanced supply rate nutrients, orchards area generally have low yield. There are few studies on fertilization areas, especially diagnosis leaf nutrition. In this study, typical Guangxi province, one main mango-producing China, were selected from...

Recently, degree of polarization (DOP) of light has been utilized as a parameter to monitor optical signal-to-noise-ratio (OSNR). However, in the presence of polarization-mode dispersion (PMD), when using DOP to determine OSNR, OSNR is always underestimated due to the depolarization effect induced by PMD. In this paper, we propose and experimentally demonstrate a simple PMD-insensitive OSNR mon...

BACKGROUND AND PURPOSES The multiplier method was introduced by Paley to calculate the timing for temporary hemiepiphysiodesis. However, this method has not been verified in terms of clinical outcome measure. We aimed to (1) predict the rate of angular correction per year (ACPY) at the various corresponding ages by means of multiplier method and verify the reliability based on the data from the...

Using a fiber-based swept-source (SS) polarization-sensitive optical coherence tomography (PS-OCT) system, we investigate the degree of polarization (DOP) of light backscattered from the retinal nerve fiber layer (RNFL) in normal human subjects. Algorithms for processing data were developed to analyze the deviation in phase retardation and intensity of backscattered light in directions parallel...

The Degree of Polarization (DoP) a light beam inside medium contains unique information about the medium. 3D imaging techniques constitute an optimal procedure for determining DoP under low conditions, as computational reconstruction process can increase signal-to-noise ratio detected light. definition division by total number photons from sensor. However, photon starved at single time period m...
