The Landsat 7 (L7) spacecraft and its instrument, the enhanced thematic mapper plus (ETM+), have been consistently characterized calibrated since launch in April of 1999. These performance metrics calibration updates are determined through U. S. Geological Survey (USGS) image assessment system (IAS), which has performing this function launch. Starting 2016, USGS adopted a tiered collection mana...

OBJECTIVE To investigate the involvement of microglial and astrocytic activation in the medullary dorsal horn (MDH) during the mediation of masseter area allodynia induced by experimental tooth movement (ETM). DESIGN Five groups of adult Sprague-Dawley rats (n=60) were divided into control (CON), minocycline (MIN), ETM, and 10mg/kg or 30mg/kg MIN plus ETM (METM) groups. The upper-first-molar ...

AIMS The aim of the ab externo trabeculectomy (AET) is to remove the external portion of the trabecular meshwork (ETM) responsible for the main aqueous outflow resistance in glaucoma patients, with no opening of the anterior chamber. ETM characteristics were evaluated with a confocal microscope. METHODS A prospective comparative observational case series was performed in 60 consecutive medica...

This work proposes the use of Genetic Algorithms (GA) as an optimization method for the Linear Mixture Model (LMM), with the purpose of fusing multispectral images that preserve the best spatial and spectral features of the source images. The algorithm proposed has been evaluated for images registered by the Landsat 7 ETM+ sensor. In this study, the high spatial resolution image (HSRI) correspo...

Gradient-descent algorithms have been successfully applied to many applications of computer vision, such as stereo matching, object recognition and medical image registration. Our work focuses on applying these techniques to remote sensing image data with a particular emphasis on data acquired under different conditions, such as multi-temporal or multi-sensor data. While most previous work has ...

BACKGROUND Safe and effective colonoscopy is aided by the use of endoscopic techniques and maneuvers (ETM) during the examination including patient repositioning, stiffening of the endoscope and abdominal pressure. AIM To better understand the use and value of ETM during colonoscopy by using a device that allows real-time imaging of the colonoscope insertion shaft. METHODS The use of ETM du...

The objectives of this investigation were to evaluate the EO-1 Hyperion hyperspectral sensor for mapping forest composition and structure in rugged terrain and to compare its performance with that of AVIRIS and the Landsat 7 Enhanced Thematic Mapper Plus (ETM+). The study focused on species composition mapping with Hyperion, AVIRIS, and Landsat using a study site in the Green Ridge State Forest...

BACKGROUND The pain caused by orthodontic treatment has been considered as tough problems in orthodontic practice. There is substantial literature on pain which has exactly effected on learning and memory; orthodontic tooth movement affected the emotional status has been showed positive outcomes. Danggui-Shaoyao-San (DSS) is a Traditional Chinese Medicine prescription that has been used for pai...

Remote sensing represents a powerful tool to derive quantitative and qualitative information about ecosystem biodiversity. In particular, since plant species richness is a fundamental indicator of biodiversity at the community and regional scales, attempts were made to predict species richness (spatial heterogeneity) by means of spectral heterogeneity. The possibility of using spectral variance...
