Generation and optimisation of colour-shaded relief maps using neural networks

open access: yesGeocarto International
Shaded relief is a primary tool used to effectively portray three-dimensional terrain on a two-dimensional plane surface. Colour-shaded relief maps use colour variations to effectively represent elevation changes and even capture the natural hues of ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Primary Forest Opening of Different Relief Areas in the Republic of Croatia

open access: yesCroatian Journal of Forest Engineering, 2011
Particularly since its independence, the Republic of Croatia has invested a lot of money into the construction of primary forest roads, and however, there is still a large lack of adequately opened forest areas, and in future this will be the object of ...

Study of the hydraulic cavitation mechanism and aperture optimization of drilling in high-gas coal seams

open access: yesFrontiers in Earth Science
To enhance gas pre-extraction efficiency in low-permeability, high-gas coal seams and eliminate the danger of coal and gas outbursts at the Wulihou Coal Mine, this study analyzed the influence of the three stress zones surrounding cavitation holes ...

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

open access: yesMolecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Possibilities of Application of Relative Openness in Secondary Forest Opening of Slope Forests in Croatia

open access: yesCroatian Journal of Forest Engineering, 2011
For achieving a high-quality and efficient management of forest ecosystems (Pentek et al. 2010), it is necessary to provide an optimally distributed network of primary and secondary forest road infrastructure.

Natural basis of geoecological processes in the region Župa Aleksandrovačka [PDF]

open access: yesGlasnik Srpskog Geografskog Društva, 2008
Natural basis is a complex, dynamic and meaningful geospatial category. Although its intensity is subject to changes, it is both a permanent determinant of social development and a physical basis of geoecological processes.
