The plastic insert in my NanoVNA H4 box went missing, so I guess I need to bite the bullet and print a rugged box and insert for it. This looks fairly good; any suggestions for alternatives to consider?

Compressing Suffix Trees by Path Decompositions
In classic suffix trees, path compression works by replacing unary suffix trie paths with pairs of pointers to $T$, which must be available in the form of some random access oracle at query time. In this paper, we revisit path compression and show that a more careful choice of pointers leads to a new elegant, simple, and remarkably efficient way to compress the suffix tree. We begin by observing that an alternative way to path-compress the suffix trie of $T$ is to decompose it into a set of (di…

Efficient Model Checking for the Alternating-Time μ-Calculus via Effectivity Frames
The semantics of alternating-time temporal logic (ATL) and the more expressive alternating-time μ-calculus (AMC) is standardly given in terms of concurrent game frames (CGF). The information required to interpret AMC formulas is equivalently represented in terms of effectivity frames in the sense of Pauly; in many cases, this representation is more compact than the corresponding CGF, and in principle allows for faster evaluation of coalitional modalities. In the present work, we investigate wh…

Intra-unit-cell singlet pairing mediated by altermagnetic fluctuations
We investigate the superconducting instabilities induced by altermagnetic fluctuations. Because of the non-trivial sublattice structure of the altermagnetic order, shorter-range and longer-range fluctuations favor qualitatively different types of pairing states. Specifically, while the latter stabilize a standard spin-triplet $p$-wave state, just like ferromagnetic fluctuations, the former leads to intra-unit-cell pairing, in which the Cooper pairs are formed by electrons from different sublatt…

Coexistence of static and dynamic local magnetic fields in an S = 3/2 honeycomb lattice antiferromagnet Co2Te3O8
Two-dimensional honeycomb lattices, characterized by their low coordination numbers, provide a fertile platform for exploring various quantum phenomena due to the intricate interplay between competing magnetic interactions, spin-orbit coupling, and crystal electric fields. Beyond the widely studied Jeff= 1/2 honeycomb systems, S = 3/2 honeycomb lattices present a promising alternative route to realizing the classical spin liquid-like state within the spin-S Kitaev models. Herein, we present cry…

Lattice Boltzmann wall boundary conditions for RANS-based simulations with wall functions
In this study, we investigate wall boundary condition schemes for Lattice Boltzmann simulations of turbulent flows modeled using RANS equations with wall functions. Two alternative schemes are formulated and assessed: a hybrid regularized boundary condition and a slip-velocity bounce-back scheme. Their performance is evaluated using two canonical turbulent flow cases, a fully developed channel flow and a zero-pressure-gradient flat plate boundary layer (BL), selected specifically to isolate and…

Her ser vi nok en gang hvordan staten og byråkratiet forsŸker å kontrollere hva unge skal tenke, mene og konsumere. Når Valgdirektoratet advarer mot unges mediebruk, handler det ikke bare om «beskyttelse» – det er også et forsŸk på å styre informasjonsflyten og forme unge til lydige borgere som ikke stiller spŸrsmål ved makta. Staten frykter at unge skal finne alternative stemmer og informasjon utenfor de etablerte kanalene, fordi det utfordrer deres monopol på sannhet og kontroll.

Buried unstrained Ge channels: a lattice-matched platform for quantum technology
Ge and Si strained quantum wells have enabled the most advanced spin-qubit quantum processors, but they are deposited on defective, metamorphic SiGe substrates, which may impact device performance and scaling. Here we introduce an alternative platform, based on a heterojunction between unstrained Ge and a strained SiGe barrier, which is lattice-matched to a Ge substrate. In a structure with a 52-nm-thick strained SiGe barrier, we demonstrate a low-disorder two-dimensional hole gas with a high-m…
