Integrative Zoology, Volume 20, Issue 4, Page 763-773, July 2025.Male frogs emit calls to attract mates and deter conspecific rivals. The evolution of these calls is thought to be linked to anatomical constraints and the acoustic characteristics of their surroundings. We tested these two factors in a radiation of 112 species of Neotropical treefrogs and found that body size and calling site affect peak frequency but

Rthoptera: Standardised insect bioacoustics in R
Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1084-1094, June 2025.Abstract Almost 100 years after the dawn of insect bioacoustics, freely available and robust analysis tools and protocols are still needed. We introduce Rthoptera, an open‐source R package designed for robust analysis of insect acoustic signals. It delivers accurate temporal and spectral measurements, along with intuitive visualisations, through a ...

Advanced Materials Interfaces, Volume 12, Issue 10, May 19, 2025.Pump‐probe shadowgraphy of glass drilling is shown with a femtosecond laser operating in MHz‐ and GHz‐burst regime. A comparison with standard femtosecond micro‐processing using repetitive single pulses is provided. The ablation plume lifetime is measured in all three regimes, and the drilling dynamics of Through Glass Via (TGV) in GHz‐burst mode are ...

Ecology and Evolution, Volume 15, Issue 4, April 2025.Urbanization fragments habitats and isolates populations, reducing gene flow and driving divergence in genetic, acoustic, and morphological traits. Over ten years, isolated populations of white‐eared ground‐sparrows exhibited increased inbreeding, altered song characteristics, and changes in body and beak size, with significant correlations found ...

Types of aeroelastic vibrations of turbomachinery bladed discs
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2017 A real process was analyzed for presence of self-oscillations. Absence of self-oscillations was revealed as its attributes such as progressive wave and beating were not discovered.

Prospects of measuring the leptonic CP phase with atmospheric neutrinos
, 2009 We have studied the prospects of measuring the CP violating phase with atmospheric neutrinos at a large magnetized iron calorimeter detector considering the muons (directly measurable) of the neutrino events generated by a MonteCarlo event generator ...

Systematic Entomology, Volume 50, Issue 2, Page 269-295, April 2025.We describe Kanakinthus koniambo, a new genus and species of the subtribe Lebinthina endemic to New Caledonia using ultrasonic calls, and three new species of the genus Agnothecous. We provide a robust dated phylogeny of the subfamily Eneopterinae using eight molecular markers and a comprehensive taxon sampling with a focus on the Western Pacific ...
