An annotated grain kernel image database for visual quality inspection
Abstract We present a machine vision-based database named GrainSet for the purpose of visual quality inspection of grain kernels. The database contains more than 350K single-kernel images with experts’ annotations. The grain kernels used in the study consist of four types of cereal grains including wheat, maize, sorghum and rice, and were collected from over…

The EPOS multi-disciplinary Data Portal for integrated access to solid Earth science datasets
Abstract The European Plate Observing System (EPOS) is a long-term initiative aimed at integrating research infrastructures for solid Earth science in Europe. EPOS provides a sustainable, multidisciplinary user-oriented platform – the EPOS Data Portal – that facilitates data integration, access, use, and re-use, while adhering to the FAIR principles. The paper describes the key governance,…

Prostate cancer treatment in Portugal: a nationwide analysis
Abstract Different treatment options exist for localized prostate cancer. Treatments performed in high-volume hospitals are associated with better results. Our objective was to describe time trends in prostate cancer treatments in Portugal and case volume per hospital. We used the national database of diagnosis-related group of the Portuguese Central Administration of the Health System to…

A Milky Way-like barred spiral galaxy at a redshift of 3
Abstract The majority of massive disk galaxies in the local Universe show a stellar barred structure in their central regions, including our Milky Way1,2. Bars are supposed to develop in dynamically cold stellar disks at low redshift, as the strong gas turbulence typical of disk galaxies at high redshift suppresses or delays bar formation3,4. Moreover,…

Sonochemical synthesis of heterostructured ZnO/Bi2O3 for photocatalytic desulfurization
Abstract In this study, metal oxides nanoparticles heterogeneous photocatalysts prepared by coprecipitation and ultrasonic techniques were used for diesel desulfurization. They were characterized by scanning electron microscope, powder X-ray diffraction, energy dispersive analysis, diffused reflectance spectra, photoluminescence analysis and BET surface area. The surface area of catalyst B is larger than catalyst A confirming its…

China must draw on internal research strength
China’s rapid rise in global science owes much to its domestic endeavours, but international partnerships have been instrumental in elevating the quality of its research output. Escalating geopolitical tensions have changed the dynamics, however, and in some countries, particularly in the West, a shift in perception towards China from cooperative partner to rival casts a…
