Land use and land cover (LULC) mapping initiatives are essential to support decision making related the implementation of different policies. There is a need for timely accurate LULC maps. However, building them challenging. changes affect natural areas local biodiversity. When they cause landscape fragmentation, monitoring affected. Due this situation, improving efforts in fragmented biomes ec...

As an essential vegetation biophysical trait that determines the plant's structure and photosynthetic capacity, characterizing of leaf area index (LAI) is important for growth health monitoring. The empirical models based on indices (VIs) from remote sensing images effective method deriving LAI. However, due to coupled impacts LAI chlorophyll content (LCC) canopy reflectance saturation effect, ...

• A band selection model - MSI for efficient and accurate vegetation mapping was described. Selecting principles: maximize separability of the target from other, information combinations. SWIR, NIR Red bands (with SWIR in particular) are effective separating mangrove other vegetation. is more suitable land cover extraction applications than full classification. described remotely-sensed cloudy ...

Introduction Sentinel lymph node biopsy is indicated for patients with biopsy-proven thickness melanoma greater than 1.0 mm. Use of lymphoscintigraphy along with vital blue dyes is the gold standard for identifying sentinel lymph nodes intraoperatively. Indocyanine green (ICG) has recently been used as a method of identifying sentinel lymph nodes. We herein describe a case series of patients wh...

Intersubband polarization couples to collective excitations of the interacting electron gas confined in a semiconductor quantum well (QW) structure. Such excitations include correlated pair excitations (repellons) and intersubband plasmons (ISPs). The oscillator strength of intersubband resonances (ISBRs) strongly varies with QW parameters and electron density because of this coupling. Using th...

The bearing of lipid solubilities and substantivities of dyes on the results of cytochemical staining reactions is briefly discussed. Solubilities of indigoid dyes in various lipids are qualitatively similar to those in symtetrachloroethane. Quantitative determinations made in this solvent indicate that, in general, indigo and its 5:5'and 6:6'-substituted derivatives are sparingly soluble, wher...

To accurately estimate leaf area index (LAI) in mangrove areas, the selection of appropriate models and predictor variables is critical. However, there is a major challenge in quantifying and mapping LAI using multi-spectral sensors due to the saturation effects of traditional vegetation indices (VIs) for mangrove forests. WorldView-2 (WV2) imagery has proven to be effective to estimate LAI of ...

BACKGROUND Sentinel node biopsy often results in the identification and removal of multiple nodes as sentinel nodes, although most of these nodes could be non-sentinel nodes. This study investigated whether computed tomography-lymphography (CT-LG) can distinguish sentinel nodes from non-sentinel nodes and whether sentinel nodes identified by CT-LG can accurately stage the axilla in patients wit...

The physiological inflammation response depends upon the multibody interactions of blood cells in the microcirculation that bring leukocytes white blood cells to the vessel walls. We investigate the fluid mechanics of this using numerical simulations of 29 red blood cells and one leukocyte flowing in a two-dimensional microvessel, with the cells modeled as linearly elastic shell membranes. Desp...

We present radio observations of the radio galaxy PKS 2152-699 obtained with the Australia Telescope Compact Array (ATCA). The much higher resolution and s/n of the new radio maps reveals the presence of a bright radio component about 10 arcsec NE of the nucleus. This lies close to the highly ionized cloud previously studied in the optical and here shown in a broadband red snapshot image with t...
