Joint retrieval of vegetation status from synthetic aperture radar (SAR) and optical data holds much promise due to the complimentary information in two wavelength domains. SAR penetrates canopy includes about water soil vegetation, whereas contains amount health leaves. However, inherent complexities combining these sources there has been relatively little progress joint over canopies. In this...

Axillary node status is a major prognostic factor in early-stage disease. Traditional staging needs levels I and II axillary lymph node dissection. Axillary involvement is found in 10%-30% of patients with T1 (<2 cm) tumours. Sentinel lymph node biopsy is a minimal invasive method of checking the potential nodal involvement. It is based on the assumption of an orderly progression of lymph node ...

BACKGROUND The European Influenza Surveillance Scheme (EISS) has collected clinical and virological data on influenza since 1996 in an increasing number of countries. The EISS dataset was used to characterise important epidemiological features of influenza activity in Europe during eight winters (1999-2007). The following questions were addressed: 1) are the sentinel clinical reports a good mea...

BACKGROUND Sentinel lymph node biopsy remains controversial for cutaneous melanoma of the head and neck (CMHN). Incidence and factors associated with recurrence after negative sentinel lymph node biopsy have not been well delineated. METHODS Characteristics of 204 patients with head and neck melanoma who had a negative sentinel lymph node biopsy were studied. Main outcomes were overall surviv...

Masking of clouds, cloud shadow, water and snow/ice in optical satellite imagery is an important step automated processing chains. We compare the performance masking provided by Fmask (“Function mask” implemented FORCE), ATCOR (“Atmospheric Correction”) Sen2Cor (“Sentinel-2 on a set 20 Sentinel-2 scenes distributed over globe covering wide variety environments climates. All three methods use ru...

OBJECTIVE To determine the level of sentinel lymph node sectioning necessary to accurately detect nodal micrometastasis. STUDY DESIGN Cross-sectional. SETTING Tertiary care university medical center. SUBJECTS AND METHODS Fine sections of oral squamous cell carcinoma sentinel lymph nodes previously sectioned at 2-mm intervals in a prospective clinical trial were reexamined. The results yie...

Monitoring of lakeshore ecosystems requires fine-scale information to account for the high biodiversity typically encountered in the land-water ecotone. Sentinel-2 is a satellite with high spatial and spectral resolution and improved revisiting frequency and is expected to have significant potential for habitat mapping and classification of complex lakeshore ecosystems. In this context, investi...

BACKGROUND After completion of axillary dissection, many breast cancer patients with axillary sentinel nodal involvement are found to have regional disease limited to the sentinel nodes. These patients are exposed to the morbidity of axillary clearance without any expected therapeutic benefit. METHODS Sentinel node biopsy was performed either with Patent blue dye or with a combined dye, radio...
