The Turbulence Properties of 150‐km Echoes in the Lower Ionosphere
Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.Abstract The valley region ionosphere spans from approximately 120–200 km in altitude, and hosts a wide range of plasma, neutral, and solar interactions that create and maintain the ionosphere. In this region a ubiquitous and mysterious source of radar echoes called “150‐km echoes” has been observed since the 1960s.

Toward Practical Silicon Anodes: Interfacial Stability, Structural Design, and Scalable Engineering
ChemBioEng Reviews, Volume 13, Issue 3, June 2026.ABSTRACT Lithium‐ion batteries (LIBs) are essential energy‐storage systems for electric vehicles and portable electronics, yet the conventional graphite anode is approaching its theoretical capacity limit. Silicon‐based anodes have emerged as promising candidates for next‐generation high‐energy LIBs owing to their exceptionally high theoretical ...

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 2, June 2026.ABSTRACT This article examines the historical displacement of Indigenous peoples in Venezuela, focusing on the links between indigenist policies and the exploitation of natural resources, particularly oil, throughout the 20th century. Using a combined historical and ethnographic approach, it demonstrates how the formation of the Venezuelan nation‐state

Probing superfluidity with quantum vortex necklaces and Leggett's bounds
Physical Review ResearchWe theoretically investigate a binary Bose-Einstein condensate in which the majority component hosts a vortex necklace, whose vortex cores act as moving effective potential wells for the minority component.

Evolution of Cosmic Necklaces and Lattices
Previously developed analytic models for the evolution of cosmic string and monopole networks are applied to networks of monopoles attached to two or more strings; the former case is usually known as cosmic necklaces.

An Efficient generic algorithm for the generation of unlabelled cycles [PDF]
In this report we combine two recent generation algorithms to obtain a new algorithm for the generation of unlabelled cycles. Sawada's algorithm lists all k-ary unlabelled cycles with fixed content, that is, the number of occurences of each symbol is

Toroidal Carbon Nanotubes with Encapsulated Atomic Metal Loops
Toroidal carbon nanotubes can serve as hosts for encapsulated loops of atomic metal wires. Such composite structures have been analyzed using density functional theory for a semiconducting C$_{120}$ torus encapsulating chains of Fe, Au and Cu atoms.
