NuRadio is an open-source, Python-based software package for the simulation, analysis and reconstruction of the radio emission from ultra-high-energy (UHE) neutrinos and cosmic rays. While NuRadio has so far mainly been used for in-ice radio neutrino detectors, such as ARIANNA, RNO-G and the future IceCube-Gen2 radio array, its modularity, provision of standard data processing steps for radio detectors, extensive documentation, and continuous integration system have allowed the LOFAR and SKA experiments to readily adopt NuRadio for the analysis of cosmic-ray air showers.This contribution will provide a brief overview of NuRadio, covering its new features and improvements to performance and usability in the past several years.

The LOw Frequency ARray (LOFAR) radio telescope possesses the unique capability to measure ultra-high energy cosmic rays as well as image lightning discharges. This study presents a comparison between the inferred thunderstorm charge structures derived from cosmic-ray measurements and from lightning flashes [...]

The Radio Neutrino Observatory in Greenland (RNO-G) is the first in-ice radio array in the northern hemisphere for the detection of ultra-high energy neutrinos via the coherent radio emission from neutrino-induced particle cascades within the ice. The array is currently in phased construction near Summit Station on the Greenland ice sheet, with 7 stations deployed during the first two boreal summer field seasons of 2021 and 2022. [...]

The accurate identification of heavy-flavour jets — those which originate from bottom or charm quarks — is crucial for precision studies of the Standard Model and searches for new physics. However, assigning flavour to jets presents significant challenges, primarily due to issues with infrared and collinear (IRC) safety. [...]

Thin film solar cell technologies are mainly based on polycrystalline absorber layers, which is also the case for kesterite-based photovoltaic devices. An alternative technology, which is promising and low cost, is based on kesterite-type C⁢u$_2$⁢ZnSn⁢(S,Se)$_4$ (CZTSSe) monograins as absorbers, which are fixed in a polymer matrix to form a flexible solar cell. [...]

High-temperature dielectric polymers are in high demand for powering applications in extreme environments. Here, we have developed high-temperature homopolymer dielectrics with anisotropy by leveraging the hierarchical structure in semicrystalline polymers [...]

Lithium-ion conductors are one of the key features of all-solid-state lithium-ion batteries. To modify their properties and enable their implementation in high-performance devices, an understanding of the relationship between the crystal structure and the transport properties of the mobile species is important [...]

Exotic quasiparticle states have been proposed in mixed-valent compounds exhibiting valence transitions. However, clear spectroscopic evidence identifying these states has remained elusive [...]

Various metastable ice phases and their complicated transition pathwayshave been found by pressurization at low temperatures at which slowkinetics and high metastability are easily achieved. By contrast, suchdiversity is less expected at room or elevated temperatures. [...]

A novel Hf$_{30.3}$Nb$_{10}$Ta$_{20.3}$Ti$_{30.3}$Al$_{9.0}$ refractory multi-principal element alloy (RMPEA) was designed with short-time annealing to achieve excellent combination of strength and ductility, surpassing most of the previouslyreported RMPEAs. The curved non-screw dislocations serve as the main plastic deformation mechanism, whilethe microband induced plasticity effect contributes to the sustained strain-hardening ability..
