Palynomorph assemblages and geochemical indicators of Neogene ocean changes in the Eastern Equatorial Pacific: Insights from DSDP Site 568

DSDP Site 568, off the west coast of Guatemala, was chosen to fill the palynological data gap in the Eastern Equatorial Pacific (EEP) region and improve tropical-to-subtropical regional paleoclimatic models of the Northern Hemisphere. This study analyses palynological assemblages...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

Annotated dataset for retinal fundus image segmentation: vascular arcade and optic nerve head

Abstract Objectives Digital fundoscopy is an ophthalmological technique used to evaluate the posterior segment of the eye, including the retina and its anatomical structures [1]. This technique acquires fundus images, visually documenting the aforementioned structures. This datas...

Green synthesis for production of chromium(III) oxide nanoparticles in fine powder

In this paper, a green synthesis method for chromium(III) oxide nanoparticles (Cr 2 O 3 NPs) is presented. The proposed route utilizes weed biomass as a reducing agent to produce a solid solution that readily precipitates as a fine powder of Cr₂O₃ nanoparticles. The synthesized C...
