With the aim to map and monitor a low-salinity water (LSW) plume in the East China Sea (ECS), we developed more robust and proper regional algorithms from large in-situ measurements of apparent and inherent optical properties (i.e. remote sensing reflectance, R rs , and absorption coefficient of coloured dissolved organic matter, a CDOM) determined in ECS(More)
Satellite ocean colour missions require a standard extraterrestrial solar irradiance spectrum in the visible and near-infrared (NIR) for use in the process of radiomet-ric calibration, atmospheric correction and normalization of water-leaving radiances from in-situ measurements. There are numerous solar irradiance spectra (or models) currently in use within(More)
Human Tousled kinase 1 (TLK1) plays an important role in chromatin remodeling, replication, and DNA damage response and repair. TLK1 activity is immediately, but transiently, downregulated after genotoxic insult, and its recovery is important for exit from checkpoint arrest and cell survival after radiation. The data in this article compliments research(More)
A reliable radiative transfer (RT) model is an essential and indispensable tool for understanding the radiative transfer processes in homogenous and layered waters, analyzing measurements made by radiance sensors and developing remote-sensing algorithms to derive meaningful physical quantities and biogeochemical variables in turbid and productive coastal(More)
UNLABELLED Patients with extensive malignancies involving the femur often require total femoral replacement when their limbs can be salvaged. Reported series are small and involve heterogeneity of tumours. We present nine patients with osteosarcomas of the femur treated at our institution between 2003 and 2010 with a mean follow-up of 27 (6 to 56) months.(More)

This paper proposes an over view of the estimation of Modulation Transfer Function (MTF) for the wave imaging mechanism. MTF correlates interaction of electromagnetic waves with dynamics of ocean surface waves. This approach is suitable for the estimation of wave parameters in the large oceanic regions. Main phenomenon occurred in between sea surface and(More)
Messages are given as text needs to be coded to avoid loss of secrecy in any transaction. This has been atempted through any media requires tough crypto analysis and can be handled through known ciphers. This job gets better results while combining the text message along with other building blocks of multimedia. In this paper a noval approach to insert a(More)
Accurate retrieval of particulate backscattering coefficients has been a great challenge in optically complex Case 2 waters. Although several models exist for retrieval of the Inherent Optical Properties (IOP's) such as particulate backscattering (b bp) from the remote sensing reflectance, these models produce b bp with high errors mainly because of(More)
