For every paper on this page, at least one of the original authors has seen our plain-language explanation and engaged with it — either confirming it reads accurately or requesting corrections that we then applied. An endorsement does not mean the authors formally approve every sentence, but it does mean the explanation has passed the eyes of the people who wrote the paper.

Learning the Exact Flux: Neural Riemann Solvers with Hard Constraints

This paper proposes a hard-constrained neural Riemann solver (HCNRS) that enforces five physical constraints—positivity, consistency, mirror symmetry, Galilean invariance, and scaling invariance—to accurately approximate exact Riemann solvers for fluid dynamics while overcoming the conservation errors and symmetry breaking issues found in unconstrained neural approaches.

Acyclic Edge Coloring of 3-sparse Graphs

This paper proves Fiamčík's conjecture that the acyclic chromatic index of a 3-sparse graph is at most Δ+2\Delta+2, and further establishes a tighter bound of Δ+1\Delta+1 for such graphs containing an edge whose endpoints have a degree sum of at most Δ+3\Delta+3, except for specific bipartite graphs where the bound remains Δ+2\Delta+2.

Quasars behind the disk of M31 galaxy

This paper presents spectroscopic follow-up of 32 quasar candidates behind the M31 galaxy, confirming 23 new or previously reported quasars to establish a homogeneous catalog of 124 reliable redshifts while revealing that current samples are biased toward brighter, less extincted objects and highlighting the significant errors associated with low-resolution spectral redshifts.

Statistics 101, 201, and 202: Three Shiny Apps for Teaching Probability Distributions, Inferential Statistics, and Simple Linear Regression

This paper introduces three open-source Shiny web applications—Statistics 101, 201, and 202—that facilitate the teaching of probability distributions, inferential statistics, and simple linear regression by providing interactive, code-free interfaces that display numerical results, visualizations, and mathematical derivations side by side.

Star Formation Beyond the Optical Disk : The Low-Density Outskirts of NGC2090

This study utilizes multi-wavelength observations, including UVIT and JWST data, to demonstrate that the extended UV disk of NGC 2090 hosts significant massive star formation with a top-heavy initial mass function, supporting an inside-out galaxy growth scenario despite the low density and metallicity of its outer regions.

Geometric Phase Effect in Thermodynamic Properties and in the Imaginary-Time Multi-Electronic-State Path Integral Formulation

This paper demonstrates that the previously developed imaginary-time multi-electronic-state path integral (MES-PI) formulation naturally captures the geometric phase effect arising from conical intersections, and quantifies its impact on low-temperature thermodynamic properties using an ad hoc GP-excluded construction as a comparison baseline.

Reproducible profiling of the gut microbiota using surplus clinical Faecal Immunochemical Test (FIT) samples

This study demonstrates that surplus Faecal Immunochemical Test (FIT) samples remain stable for up to 14 days and yield bacterial 16S rRNA sequencing results comparable to standard whole-stool samples, validating their use for large-scale, low-cost gut microbiota research.
