350-GHz Bandpass Filters Using Superconducting Coplanar Waveguide

IEEE Transactions on Terahertz Science and Technology, 2021
On-chip filters play an invaluable role in most detectors and instruments, blocking unwanted, harmonic, or mirrored signals. In this article, two coplanar waveguide bandpass filters working at 350 GHz are designed based on quarter-wavelength stepped ...

Goldfish: Monolingual Language Models for 350 Languages

arXiv.org
For many low-resource languages, the only available language models are large multilingual models trained on many languages simultaneously. Despite state-of-the-art performance on reasoning tasks, we find that these models still struggle with basic ...

Optimization of Railway Pantograph-Catenary Systems for Over 350 km/h Based on an Experimentally Validated Model

IEEE Transactions on Industrial Informatics
The pantograph-catenary system is widely used in most electrified rail networks around the world to transmit continuous electric current to the train. Most studies about the pantograph-catenary interaction are performed at a speed of lower than 350 km/h.

Liquid metal embrittlement susceptibility of a high-entropy alloy exposed to oxygen-depleted liquid lead-bismuth eutectic at 250 and 350 °C

Journal of Nuclear Materials, 2020
Liquid metal embrittlement (LME) susceptibility of a high-entropy alloy (HEA) with a nominal composition of Fe40Mn10Ni10Co20Cr20 (at.%) and a single face-centered cubic (fcc) structure was tested in oxygen-depleted lead-bismuth eutectic (LBE, Pb44.5Bi55 ...

Precipitation and reverted austenite formation in maraging 350 steel: competition or cooperation?

Acta Materialia
Aged maraging steels offer unique strength and toughness via the presence of finely dispersed precipitates, allowing the material to reach values of up to 2400 MPa in yield strength in the case of 18Ni350. However, when aging heat treatments above 550 °C
