Capability of Integrated MODIS Imagery and ALOS for Oil Palm, Rubber and Forest Areas Mapping in Tropical Forest Regions

open access: yesSensors, 2014
Various classification methods have been applied for low resolution of the entire Earth’s surface from recorded satellite images, but insufficient study has determined which method, for which satellite data, is economically viable for tropical forest ...

Terrain classification by cluster analisys [PDF]

open access: yes, 1988
The digital terrain modelling can be obtained by different methods belonging to two principal categories: deterministic methods (e.g. polinomial and spline functions interpolation, Fourier spectra) and stochastic methods (e.g.

Assessing forest fragmentation and biodiversity impacts in sub‐Saharan Africa: Methodological challenges and conservation strategies for small‐scale agricultural landscapes

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Tropical forests in sub‐Saharan Africa (SSA) harbor around one‐third of the world's species but are becoming more fragmented due to the expansion of human settlements and small‐scale agricultural (SCA) areas. This study systematically reviewed the approaches and methods used to analyze forest fragmentation and its impact on biodiversity in SSA,

Nanoscopic Mapping of the Extracellular Space in Amyloid Plaque‐rich Cortex

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
The extracellular space and diffusion around amyloid plaques are examined using shadow imaging and single‐particle tracking. Increased diffusivity is found near plaques, extracellular matrix alterations, and plaque core penetrability that varies with amyloid phenotype.

The Absence of Collagen VI Reduces Systolic Function but Paradoxically Increases Ca2+ Release in the Rat Heart

open access: yesActa Physiologica, Volume 242, Issue 1, January 2026.
ABSTRACT Aim Collagen VI has recently been strongly linked to poor outcomes in heart failure through increased endotrophin, a collagen VI‐derived signaling molecule linked to fibrotic remodeling in cardiovascular disease. The mutation of collagen VI can result in Ullrich congenital muscular dystrophy and Bethlem myopathy, pointing to a critical ...

Segmentation and classification of high spatial resolution images based on Hölder exponents and variance

open access: yesGeo-spatial Information Science, 2017
Pixel-based or texture-based classification technique individually does not yield an appropriate result in classifying the high spatial resolution remote sensing imagery since it comprises textured and non-textured regions.

Use of geographical and socio-economical information to support the risk assessment of foot and mouth disease in the frontier between Brazil and Paraguay [PDF]

open access: yes, 2009
ln 2001, Brazil was able to eliminate the outbreaks of Foot and Mouth Disease (FMD) in bovine herds. After that, meat exports had an increase of 200%. However, in September 2005 occurred a FMD outbreak in the State of Mato Grosso do Sul (MS) and Parana ...

Concurrent Response of Soybean to Fixed (Full and Limited) and Variable Rate Irrigation Management in Three Soil Types: II. Growth, Yield, Evapotranspiration and Water Productivity

open access: yesIrrigation and Drainage, Volume 74, Issue 5, Page 1874-1888, December 2025.
ABSTRACT Soybean growth, yield, crop evapotranspiration (ETc) and crop water use efficiency (CWUE or crop water productivity, CWP) under different irrigation levels in three different soil types in the same field were investigated concurrently. Treatments in each soil type were: (i) variable rate irrigation (VRI), (ii) fixed rate full irrigation (FR‐1″)

Autonomous clustering using rough set theory [PDF]

open access: yes, 2008
This paper proposes a clustering technique that minimises the need for subjective human intervention and is based on elements of rough set theory. The proposed algorithm is unified in its approach to clustering and makes use of both local and global ...
