On the stellar content of the open clusters Melotte 105, Hogg 15, pismis 21 and Ruprecht 140 [PDF]

open access: yes, 2001
CCD observations in the B, V and I passbands have been used to generate colour-magnitude diagrams reaching down to V = 19 mag for two slightly characterized (Melotte 105 and Hogg 15) and two almost unstudied (Pismis 21 and Ruprecht 140) open clusters ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, EarlyView.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

The Inclusion Trade‐Off: Comparing the Design and Functionality of Collaborative Governance Forums

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Environmental challenges require collaboration across jurisdictions, often through forums or intermediary spaces for repeated interaction. A persistent forum design question concerns inclusion criteria, or which actors should be included.

Galaxy sizes and compactness at Cosmic Dawn

open access: yesAstronomy & Astrophysics
Context. The James Webb Space Telescope has found an unexpected population of high-mass galaxies (log(M★/M⊙)≳10) with extremely small effective radii (∼100 pc) at z ≳ 6. Also, the existence of an unusual size–mass relation has been claimed.

Anti‐Astrotropik — Outer Space, Technology and Resistance in the Tropics

open access: yesSingapore Journal of Tropical Geography, EarlyView.
This paper traces an intellectual and geographical arc of thinking about outer space in the tropics, connecting Peter Redfield's Space in the Tropics: From Convicts to Rockets in French Guiana (2000), Sean T. Mitchell's Constellations of Inequality: Space, Race, and Utopia in Brazil (2017) and Asif Siddiqi's Cosmic Fragments: Dislocation and Discontent

Ocean Wave Modulation of Offshore Wind Turbine Loads and Wake

open access: yesWind Energy, Volume 29, Issue 6, June 2026.
ABSTRACT This study examines how wave‐induced modulation affects the operational performance and structural dynamics of fixed‐bottom offshore wind turbines operating under a neutral atmospheric boundary layer profile. To capture these effects accurately while maintaining computational efficiency, unsteady RANS modelling techniques are employed.

“Humanizar”: aprendizajes sobre alteridad, salud y futuro en una experiencia de investigación compartida

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.
ABSTRACT The visit to Bogotá of a fééeneminaa (Muinane) friend, Célimo Nejedeka Jifichíu, and in particular, his work in researching and transmitting traditional health knowledge, offer the pretext to navigate the relationship between elements that at first glance seem distant from each other: indigenous imaginaries about otherness, their visions of ...

Origin of the bilateral structure of the supernova remnant G296.5+10 [PDF]

open access: yes, 2017
In this work, we have modelled the supernova remnant (SNR) G296.5+10, by means of 3D magnetohydrodynamics (MHD) simulations. This remnant belongs to the bilateral SNR group and has an additional striking feature: the rotation measure (RM) in its eastern ...
