Determining bismuth content in GaAsBi alloys by energy‐dispersive X‐ray spectroscopy: A case study with multiple sets of k*‐factors for analytical transmission electron microscopy

Journal of Microscopy, EarlyView.
Abstract Measuring the bismuth (Bi) content of ternary gallium arsenide bismuthide (GaAsBi) alloys is important because it sensitively influences their bandgap, and Bi is known to segregate vertically to the surface and sometimes also laterally during growth, so elemental distribution maps need to be quantified.

Syrinx anatomy and vocalizations in New World vultures (Aves: Cathartidae): Implications for avian vocal evolution

Journal of Anatomy, EarlyView.
New World vultures are the only avian clade proposed to lack a syrinx and have been described as non‐vocal. Using dissection, diceCT, and histology, we demonstrate that cathartid vultures have novel syringeal features that form a syrinx and vocal characterization reveals that they produce more complex vocalizations than previously reported.

Optimization of a Time-of-Arrival-Ridge Estimation Iterative Model for Ultra-Wideband Positioning in a Long Linear Area

Sensors
Ultra-wideband (UWB) technology is widely used for high-precision indoor positioning due to its adaptability to various environments. However, in long linear areas, such as tunnels or corridors, the near-linear deployment of base stations caused by ...

Hormesis without evolution: plastic compensatory responses to herbicide drift in Oxalis stricta, a common weed of agriculture

New Phytologist, EarlyView.
Conceptual framework linking herbicide dose–response to plant fitness outcomes under sublethal exposure. Summary Herbicide drift exposes nontarget plants to sublethal agrochemical doses, yet its ecological and evolutionary consequences remain poorly understood.

Sir and Guys in 20th‐ and 21st‐Century American English

World Englishes, EarlyView.
ABSTRACT This paper examines the diachronic development of formal and informal address and reference terms in American English as an effect of democratization using the COHA corpus (1900–2020). In focus are two address/reference terms with especially drastic frequency trends in the timespan investigated: the honorific sir, which declines sharply from ...
