Radial-velocity measurements of subdwarf B stars [PDF]

open access: yes, 2011
Subdwarf B (sdB) stars are hot, subluminous stars which are thought to be core-helium burning with thin hydrogen envelopes. The mechanism by which these stars lose their envelopes has been controversial, but it has been argued that binary star ...

Variabilidad radial física y anatómica del leño de árboles de Amburana cearensis

open access: yesColombia Forestal, 2018
Existen pocos estudios relacionados con microdensitometría de rayos X en madera de bosques tropicales nativos. Este estudio tuvo como objetivo determinar la variación radial de la densidad aparente del leño de Amburana cearensis (Allemão) A.C.Sm.

Precipitation shapes colour polymorphism in a widespread spider

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Colour polymorphism, the presence of multiple colour variants within a population, is a common example of intraspecific phenotypic variation and has served as a model for studying drivers of diversity.

Ecology of declining populations of gray foxes (Urocyon cinereoargenteus) in Indiana, USA Ecología de las poblaciones en declive de zorros grises (Urocyon cinereoargenteus) en Indiana, EE.UU.

open access: yesWildlife Monographs, Volume 226, Issue 1, September 2026.
We estimated seasonal space use, cover selection, and resource selection; evaluated gene flow and potential genetic barriers; and assessed cause‐specific survival rates and reproduction of radiomarked gray foxes in Indiana, USA. Our results provide evidence that gray foxes in Indiana are an edge species with relatively large home ranges, relatively low

Experimental and Numerical Investigation of Unforced unsteadiness in a Vaneless Radial Diffuser [PDF]

open access: yes, 2011
The paper reports combined experimental and numerical investigations of unforced un- steadiness in a vaneless radial diffuser. Experimental data were obtained within the diffuser using stereoscopic time resolved Particle Image Velocimetry (PIV) recording

Influence of the constitutive flow law in FEM simulation of the Radial forging process [PDF]

open access: yes, 2013
Radial forging is a widely used forming process for manufacturing hollow products in transport industry. As the deformation of the workpiece, during the process, is a consequence of a large number of high-speed strokes, the Johnson-Cook constitutive law (

Which, when, and where traits matter: functional trait‐mediated species associations shift with microenvironmental and climatic variation

open access: yesNew Phytologist, Volume 251, Issue 5, Page 2468-2481, September 2026.
Community‐level fitted relationship between spatial association Lij and trait dissimilarity (tDij) at the fine spatial scale (r = 40 mm; where r represents the radius around individuals of the focal species). Summary Predicting coexistence in species‐rich plant communities requires understanding the role of functional traits in species interactions and
