Leaf nitrogen concentration (leaf N, %) is an essential component for understanding biogeochemical cycling. Leaf N is a good indicator of grass or forage quality, which is important for understanding the movements and feeding patterns of herbivores. Leaf N can be used as input for rangeland carrying capacity and stocking rate models. The estimation of leaf N has been successful using hyperspect...

OBJECTIVE To assess the feasibility of computed tomography (CT) lymphography using ethiodized oil for sentinel node mapping in experimentally induced VX2 carcinoma in the rabbit thigh. MATERIALS AND METHODS This experiment received approval from the institutional animal use and care administrative advisory committee. Twenty-three rabbits with VX2 carcinoma in the thigh underwent CT before and...

Soil moisture is an essential parameter for a better understanding of water processes in the soil–vegetation–atmosphere continuum. Satellite synthetic aperture radar (SAR) well suited monitoring content at fine spatial resolutions on order 1 km or higher. Several methodologies are often considered inversion SAR signals: machine learning techniques, such as neural networks, empirical models and ...

Abstract. Soil moisture is a vital parameter for environmental research such as agriculture, hydrology, natural resources, hazards, etc. It essential to have timely soil maps prepared with high accuracy, speed, and low cost. Therefore, in this study, an attempt was made evaluate the efficiency of Sentinel 1 2 sensor images some cases prepare map. For sampled at 24 points common area two south M...

sentinel lymph node is the first regional lymph node that drains the lymph from the primary tumor. it is potentially the first nodeto receive the seeding of lymph‑borne metastatic cells. this study aimed to discuss lymphoscintigraphy procedural guidelines fordetection of sentinel node using tc‑phytate in isfahan, iran. moreover, the preliminary results of the first year’s clinical experience of...

This paper presents an evaluation of the multi-source satellite datasets such as Sentinel-2, Landsat-8, and Moderate Resolution Imaging Spectroradiometer (MODIS) with different spatial and temporal resolutions for nationwide vegetation mapping. The random forests based machine learning and cross-validation approach was applied for evaluating the performance of different datasets. Cross-validati...

PURPOSE To investigate the safety and clinical utility of the sentinel node procedure in early-stage vulvar cancer patients. PATIENTS AND METHODS A multicenter observational study on sentinel node detection using radioactive tracer and blue dye was performed in patients with T1/2 (< 4 cm) squamous cell cancer of the vulva. When the sentinel node was found to be negative at pathologic ultrasta...

This paper elaborates the Sentinel-2 image processing approaches used for the estimation of the population of an area of interest at Image CLEF Remote 2017 lab by the FabSpace 2.0 Darmstadt team. The task is introduced by Image CLEF Lab as a new pilot task in 2017 (Remote) which aims at exploring Copernicus Earth Observation data (i.e. Sentinel-2 satellite imagery) in order to estimate the popu...

ESA's upcoming satellite Sentinel-2 will provide Earth images of high spatial, spectral and temporal resolution and aims to ensure continuity for Landsat and SPOT observations. In comparison to the latter sensors, Sentinel-2 incorporates three new spectral bands in the red-edge region, which are centered at 705, 740 and 783 nm. This study addresses the importance of these new bands for the retr...

introduction: many radiotracers have been used for sentinel node mapping with acceptable results. the main difference between these radiotracers is the particle size. in the current study, we reported defective labeling of tc-99m antimony sulfide colloid which resulted in large particle size. methods: tc-99m-antimony sulfide colloid was used for axillary sentinel node mapping of 45 breast cance...
