Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae)

American Journal of Primatology, Volume 88, Issue 1, January 2026.
Spectral parameters of vocalizations distinguish lion tamarin species. Peak frequency, center frequency, and frequency at 5% and 95% were the most informative measures for separating species, with the trill being the vocalization that showed the most differences, and Leontopithecus caissara being the most distinct species of all.

Observation of superluminal geometrical resonances in Bi2Sr2CaCu2O8+x intrinsic Josephson junctions

, 2010
We study Fiske steps in small Bi2Sr2CaCu2O8+x mesa structures, containing only few stacked intrinsic Josephson junctions. Careful alignment of magnetic field prevents penetration of Abrikosov vortices and facilitates observation of a large variety of ...

Solution‐Processed Magnesium Oxide Buffer Layer for Improved Stability of CsPbI2Br Perovskite Solar Cells

Solar RRL, Volume 10, Issue 1, January 2026.
An interfacial engineering strategy incorporating magnesium oxide (MgO) between the ZnO electron transport layer and CsPbI2Br is demonstrated. This approach yields perovskite solar cells with improved film morphology, charge mobility, and stability. Proton‐irradiated MgO‐incorporated devices retain their performance after 11 weeks, whereas the control ...

The influence of power and frequency on the filamentary behavior of a flowing DBD-application to the splitting of CO2

, 2016
In this experimental study, a flowing dielectric barrier discharge operating at atmospheric pressure is used for the splitting of CO2 into O2 and CO. The influence of the applied frequency and plasma power on the microdischarge properties is investigated

Multidimensional Fingerprinting Strategy for the Quality Evaluation of Sporoderm‐Broken Ganoderma lucidum Spores

Journal of Food Quality, Volume 2026, Issue 1, 2026.
It remains challenging to improve the quality standard system of Traditional Chinese Medicine (TCM) for TCM development. Currently, it is urgently needed to develop an integrated, effective, and scientific approach to improve the efficacy, safety, and quality consistency of sporoderm‐broken spores of Ganoderma lucidum (SSGL).

Studies of the Fractional Selkov Dynamical System for Describing the Self-Oscillatory Regime of Microseisms

Mathematics, 2022
A non-linear fractional Selkov dynamic system for mathematical modeling of microseismic phenomena is proposed. This system is a generalization of the previously known Selkov system, which has self-oscillatory modes and is used in biology to describe ...

Ecological Exposure History Shapes Giraffe Vigilance Responses to Anthropogenic Noise: A Multisite Playback Experiment

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Understanding how animals respond to anthropogenic disturbance is essential for predicting the impacts of human activity on wildlife behavior and persistence. As noise increasingly alters sensory landscapes across ecosystems, it can influence how animals detect threats and assess risk.
