Ringing Noise Reduction Method for High‐Speed GaN Switching Converter

physica status solidi (a), Volume 222, Issue 23, December 2025.
The noise reduction circuit for decreasing the ringing voltage peaks in the switching converter with GaN‐based high electron mobility transistors is proposed. First, the location of the stray inductance generating the ringing noise is investigated using radiated emission measurements, and the additional capacitor is inserted into the circuit in ...

Robust Ferroelectricity in Micrometer–Thick Ce:HfO2 Films

Advanced Electronic Materials, Volume 11, Issue 19, November 18, 2025.
This manuscript presents a 3–µm–thick Ce:HfO2 ferroelectric film with distinctive {111} –preferred, single–crystal–like columnar grains with embedded nanopores. Raman characterizations reveal that the film contains an orthorhombic phase fraction of ≈21% (25 °C) and exhibits a Tc of ≈400 °C.

Neandertal Cold Adaptation: Technological, Anatomical, and Physiological Responses to Cold Stress in One of Our Closest Fossil Relatives

American Journal of Human Biology, Volume 37, Issue 10, October 2025.
ABSTRACT Neandertals occupied western Eurasia for over 100 000 years, repeatedly enduring climates that ranged from seasonally cold to glacial. This paper reexamines the question of Neandertal cold adaptation using updated fossil, physiological, and archaeological evidence.
