Identification and observed changes in the rainy season onset and termination in Central Chile
The onset and termination of the rainy season shape the planning and operation of water resources systems. Thus, we identify the onset and termination in Central Chile (32–40°S) from 1960 to 2021 based on the occurrence of frequent wet spells (consecutive days with rainfall ≥1 mm...

How Later SEC Comparatives Leak Into Historical Backtests: A CoreWeave Case Study
This reproducible case study examines how later SEC comparative values can leak into an earlier historical backtest when a financial-data warehouse destructively retains only the latest value for each issuer, taxonomy concept, unit and fiscal period. The study matches 14 CoreWeav...

Ground-State Phase Diagram of the S = 1 Kitaev-Γ Model on a Bond-Anisotropic Honeycomb Lattice
We obtain the ground-state phase diagram of the S = 1 Kitaev-Γ model on a bond-anisotropic honeycomb lattice using exact diagonalization, density-matrix renormalization group, and infinite time-evolving block decimation. The Tomonaga–Luttinger liquid region of the S = 1/2 model i...

Dispersion-Contrasting Dual-Layer Metalens for Hybrid Chromatic-Aberration Correction in the Visible
Abstract Metalenses offer a pathway toward flat, wafer-level optics, but their translation to mobile imaging has been hindered by the difficulty of achieving broadband performance at millimeter-scale apertures. Here we report a visible metalens that imparts a wavelength-invariant...

A Bayesian Approach to Nuclear Spin Relaxation Phenomena in Topological Kondo Insulator SmB 6
In studies of the promising topological Kondo insulator (TKI) candidate SmB 6 , nuclear magnetic resonance (NMR) measurements of the spin–lattice relaxation rate, 1/T 1 , have provided crucial insights into this compound: for example, the unique opening of a small hybridization g...
