Separation-Dependent Bell Correlations from Prepared Coherence in Dirac Wavepackets

A free-packet model treats a prepared joint Dirac electron wave as a physical entity and computes Bell-CHSH correlations that weaken and revive with station separation, without invoking signal transmission between detectors. Interference between direct and exchanged wave assignments modulates the optimized spin response.

GLIMPSE-DDT spectroscopic properties of faint-end galaxies at $z\sim6$: Towards first metal enrichment, dust production, and ionizing photon production

JWST/NIRSpec spectra from the GLIMPSE survey's Abell S1063 lensing field cover sixteen galaxies fainter than M_UV = -17 near redshift six. Strong [OIII] emission extends the mass-metallicity relation down to about a million solar masses, suggesting two separate paths to early metal enrichment.

A Diagrammatic Method for Non-Gaussian Photon Correlations in Weakly Coupled Atomic Ensembles

The authors build a scattering-theory formalism using a perturbative diagrammatic expansion, predicting that a resonantly driven ensemble of atoms, weakly coupled to an optical mode, can produce non-Gaussian photon correlations. They derive an optical-depth-dependent bound on truncation error and benchmark it against simulations.

EnsAI: An Emulator for Atmospheric Ammonia Ensembles

Researchers present EnsAI, an AI-based system for generating ensembles of surface ammonia concentrations. Trained on output from the GEM-MACH air quality model, it reproduced meteorology-dependent ensemble features while producing ensembles roughly 3,300 times faster and yielded comparable emissions-inversion results with less computation.

ZTF SNe Ia DR2: Towards cosmology-grade ZTF supernova light curves using scene modeling photometry

The ZTF SN Ia DR2 sample includes 3628 spectroscopically confirmed Type Ia supernovae from the survey's first 2.5 years. Scene Modeling Photometry yields consistent stretch and color with forced photometry, but a sensor 'pocket-effect' causes non-linearities that currently block cosmology-grade use.

Green building blocks reveal the complex anatomy of climate change mitigation technologies

By comparing functionally similar green and non-green patents, researchers identify "Green Building Blocks": modular components that can be added to existing technologies to cut their carbon footprints. The resulting network links polluting technologies to mitigating components, helps predict which green technologies firms pursue, and shows that for most US, German and Chinese firms the most complementary partners are located abroad.

Open Biomedical Knowledge Graphs at Scale: Construction, Federation, and AI Agent Access with Samyama Graph Database

A Rust-native graph database called Samyama underpins an open biomedical knowledge graph ecosystem that merges sources such as Reactome, DrugBank and ClinVar into 328.1 million nodes and 1.44 billion edges. Schema-driven MCP tools reportedly scored 98% on the 40-question BiomedQA benchmark.
