PURPOSE To investigate the expression of functional gap junctions and the effect of protein kinase C (PKC) on such junctions in confluent cultures of bovine trabecular meshwork (TM) cells. METHODS Expression of the gap junction protein connexin43 in TM cells was examined by immunofluorescence microscopy. Intercellular communication by gap junctions was assessed by observing the diffusion of f...

We tested a supervised classification approach with Landsat 5 Thematic Mapper (TM) data for time-series mapping of seagrass in a subtropical lagoon. Seagrass meadows are an integral link between marine and inland ecosystems and are at risk from upstream processes such as runoff and erosion. Despite the prevalence of image-specific approaches, the classification accuracies we achieved show that ...

In this work, we propose novel schemes to design on-chip ultra-compact optical directional couplers (DC) and broadband polarization beam splitters (PBS) based on off-centered and asymmetric dielectric slot waveguides, respectively. Slot dimensions and positions are optimized to achieve maximum coupling coefficients between two symmetric and non-symmetric slotted Si wire waveguides through overl...

China is experiencing a drastic loss of arable land as a result of the continuing process of rapid urbanization. This loss could have an adverse impact not only on China’s sustainable development but also on the world food market. To provide a robust and economical tool for evaluating the impact of this process, we developed an IHS (Intensity, Hue, Saturation)-based approach for detecting the c...

Retrieval of the surface reflectance is important in the remotely sensed data analysis to obtain the atmospheric reflectance or atmospheric correction. The relationship between visible and mid infrared reflectance over land was investigated and developed in this study. The surface reflectances of the two visible bands were measured using a handheld spectroradiometer collected around Penang Isla...

This study assesses the ability of multitemporal Landsat Thematic Mapper (TM) data and the normalized diVerence vegetation index (NDVI) to spectrally separate grazed cool season and warm season grassland cover types in Douglas County, Kansas. Biophysical data collected during the summer of 1997 suggest that diVerences in the per cent of total living vegetation cover, per cent of senescent veget...

Transition metal (TM) ion activated phosphors are increasingly being used as probes for luminescence thermometry. Their is characterized by strong absorption and emission bands that span the visible near-infrared spectral ranges highly susceptible to temperature variations. Due latter characteristic, sensitive reliable remote measurements can be performed observing temperature-induced changes i...

this research was done in order to submit a model for salinity map made with tm satellite data and salinity values in a buienzahra. the necessary processings such as principal component analysis and producing of different indices was done on the main bands. the 38 soil samples using random sampling (with 10×10 km dimension) from different horizons were designed and performed on the study area. ...

Orthogonal subspace projection (OSP) has been successfully applied in hyperspectral image processing. In order for the OSP to be effective, the number of bands must be no less than that of signatures to be classified. This ensures that there are sufficient dimensions to accommodate orthogonal projections resulting from the individual signatures. Such inherent constraint is not an issue for hype...

Thulium-doped calcium fluoride (Tm:CaF2) single-crystalline films are grown on (100)-oriented undoped bulk CaF2 substrates by Liquid Phase Epitaxy (LPE) using LiF as a solvent. Their spectroscopic properties studied in details. For ~2 at.% Tm-doped films, the active ions predominantly isolated and located oxygen-assisted trigonal sites, C3v(T2). With increasing Tm doping level, ion clustering i...
