The VCD spectra of lanthanide chelates with two chiral ligands display conserved sequences of bands throughout the Ln series. Some compounds (Tm, Yb) feature increased bands and strongly improved signal-to-noise ratios, an effect we dub Lanthanide Induced VCD Enhancement (LIVE).

The ability to detect and quantify changes in the Earth’s environment depends on satellites sensors that can provide calibrated, consistent measurements of Earth’s surface features through time. A critical step in this process is to put image data from subsequent generations of sensors onto a common radiometric scale. To evaluate Landsat-5 (L5) Thematic Mapper’s (TM) utility in this role, image...

The geometric, electronic, magnetic, thermal, and optical properties of transition metal (TM) doped silicene are systematically explored using spin-dependent density functional computation. We find that the TM atoms decrease buckling degree structure caused by interaction between dopant Si in layer plane which is quite strong. In some TM-silicenes, parallel bands corresponding van Hove singular...

We present a systematic study of the electronic and magnetic properties of transition-metal TM atomic chains adsorbed on the zigzag single-wall carbon nanotubes SWNTs . We considered the adsorption on the external and internal wall of SWNT and examined the effect of the TM coverage and geometry on the binding energy and the spin polarization at the Fermi level. All those adsorbed chains studied...

The National Aeronautics and Space Administration (NASA) Landsat program has been dedicated to sustaining data continuity over the 20-year period during which Landsat Thematic Mapper (TM) and Enhanced TM Plus (ETM+) sensors have been acquiring images of the earth's surface. In 2000, NASA launched the Earth Observing-1 (EO-1) Advanced Land Imager (ALI) to test new technology that could improve t...

The valence hole subbands, the TE and TM mode optical gains and radiative current density of In0.2Ga0.8As/GaAs compressively strained quantum well lasing at 980nm have been studied by using a 6x 6 Hamiltonian model including the heavy hole, light hole and spin-orbit splitting bands. The compressively strain enhances the TE mode optical gains and strongly depresses the TM mode optical gain. A ve...

In this study, a sharpening method based on a neural network (NN) approximation technique is described to increase the spatial resolution of thematic mapper (TM) thermal-infrared (T-IR) data. Sharpening is derived from a learned input-output mapping of edge contrast patterns between TIR and higher resolution TM bands. This method is similar to a reported adaptive least squares (LS) method to es...

The paper describes the use of Principal Component Analysis (PCA) of remote sensing images as a method of change detection for the Kafue Flats, an inland wetland system in southern Zambia. The wetland is under human and natural pressures but is also an important wildlife habitat. A combination of Landsat MSS and TM images were used The images used were from 24 September 1984 (MSS), 3 September ...

empirical models are important tools for relating field-measured biophysical variables to remotely sensed data. regression analysis has been a popular empirical method of linking these two types of data to estimate variables such as biomass, percent vegetation canopy cover, and bare soil. this study was conducted in a semi-arid rangeland ecosystem of qazvin province, iran. this paper presents t...
