When invasions go unnoticed: Public perception of the freshwater jellyfish Craspedacusta sowerbii in Europe

People and Nature, EarlyView.
Abstract Biological invasions are a major driver of biodiversity loss, yet inconspicuous or “cryptic” species often escape detection and public awareness, limiting management responses. We investigated the freshwater jellyfish Craspedacusta sowerbii, likely native to China and now present on six continents, through a 22‐month multilingual online survey

UBVI CCD Photometry of the Old Open Cluster NGC 1193

, 2008
We present UBVI photometry of the old open cluster NGC 1193. Color-magnitude diagrams (CMDs) of this cluster show a well defined main sequence and a sparse red giant branch.

Enhancing Charge Transport and Extraction in Ta3N5 Photoanodes Via Ti Doping and TiN Contact Layers

Small, EarlyView.
Ta3N5${\rm Ta}_3{\rm N}_{5}$ is a promising photoanode for solar water splitting but suffers from poor charge transport and interfacial losses. We combine Ti compensation doping with ultrathin TiN back‐contact interlayers to suppress bulk recombination, enhance carrier mobility and lifetime, and enable efficient carrier extraction, yielding ...

UOCS-XIX. A Multiwavelength Study of Open Cluster Trumpler 5: Cluster Properties and Exotic Populations

The Astronomical Journal
Trumpler 5 is a populous, intermediate-age (∼3 Gyr), metal-poor ([Fe/H] ∼ −0.4) open cluster, located at a distance of approximately ∼3050 pc. This is a well-studied cluster for its broadened main-sequence (MS) and blue straggler star (BSS) population ...

Stellar Collisions and Blue Straggler Formation

, 2001
We review recent 3D hydrodynamic calculations of stellar collisions using the Smoothed Particle Hydrodynamics (SPH) method, and we discuss the implications of the results for the formation and evolution of blue stragglers in globular clusters. We also discuss the construction of simple analytic models for merger remnants, approximating the mass loss ...

Ultrahigh Stiffness and Energy Absorption Properties of Isotropic Metallic Closed Cell Microlattices

Small, EarlyView.
True closed cell microlattices without holes are fabricated for the first time using a novel Laser Sheet Fusion additive manufacturing technique. These microlattices exhibited isotropy in stiffness and surprisingly, strength and plasticity as well, despite orientation‐dependent failure mechanisms. Furthermore, material work hardening is shown to be key

The Impact of Stellar Rotations and Binaries on the Shape of Upper Main Sequence near Turnoff in Open Cluster NGC 6067

The Astrophysical Journal
We present the analysis of the extended main-sequence turnoff (eMSTO) in the open cluster NGC 6067. We derive the projected rotational velocity, v sin i , of the stars belonging to the eMSTO region of the main sequence (MS) utilizing Gaia-ESO spectra ...
