Convert electrode potentials with supplied SHE offsets only when declared conditions match. Explicit sign convention; no reference-data or area validation.

Align authorized declared edition locators for a supported Maha book, with unmapped and ambiguous states. No arbitrary PDF parsing or inferred textual equivalence. New modular adapter: retained resul…

Parse a bounded formula with parentheses using a pinned 30-element average-mass table. Return composition and molar mass; no isotopes, purity or safety claim.

Relate supplied film thickness, resistivity and sheet resistance under stated uniform-film assumptions. For arithmetic checks; no measured device-performance claim.

Build an astronomy or astrology tool with seven classical-body geocentric longitudes at one UTC instant, Tropical and versioned Lahiri Sidereal frames, conventions and a deterministic receipt. Public…

Fit positive rate-temperature observations by log-linear Arrhenius OLS; return activation energy, residuals and transformed-fit errors. No mechanism or extrapolation claim.

Calculate a surface-code resource scenario under an explicitly named layout and supplied error assumptions. For planning; not a demonstrated physical implementation.

Calculate first-order Bragg spacings from supplied two-theta peaks and wavelength. Explicit units; no lattice indexing or unique phase identification.

Check a declared bandwidth and up to 16 tones against the strict Nyquist inequality, with equality reported separately. Computes folded tone frequencies exactly. Assumes uniform sampling, bandlimited…

Deterministic approximate GMST geometry at supplied UTC samples, site and frozen equatorial positions; no refraction, weather, live data or continuous visibility claims.

Get an inspectable exact solution to a 1-8 variable rational linear system. Returns rank, pivots, particular solution and null space; distinguishes unique, inconsistent and underdetermined systems. N…

Compare circuit durations with supplied T1/T2 values using an explicit relaxation/dephasing model. For scenario planning; not a measured device-fidelity guarantee.

Fit supplied randomized-benchmarking decay observations with residuals and protocol-bound error estimates. Not a platform-independent quantum-computer ranking.

Estimate differential strain from supplied expansion coefficients and temperature changes. For preliminary scenarios; no stress, delamination or reliability certification.

Parse supplied SMILES and report valence, stereochemistry and representation problems before molecular-data processing. Structural parsing does not establish safety.

Deterministic approximate GMST geometry at supplied UTC samples, site and frozen equatorial positions; no refraction, weather, live data or continuous visibility claims.

Get an inspectable exact solution to a 1-8 variable rational linear system. Returns rank, pivots, particular solution and null space; distinguishes unique, inconsistent and underdetermined systems. N…

Inspect structured sample assignments for technical/biological replication and batch confounding before comparing experimental groups. No causal conclusion from labels alone.

Fit supplied substrate/rate pairs by reciprocal Lineweaver-Burk OLS; report Km, Vmax and residuals. Exposes noise bias; no parameter confidence interval.

Great-circle angles for bounded caller-supplied right ascension and declination pairs in integer microdegrees; no ephemeris lookup. New modular adapter: retained result recovery for 24 hours, minimal…

Prepare a reproducible research handoff from supplied public or synthetic artifact contents, dependencies, algorithm version, seed and Supplied-record analysis, not independent certification. Full co…

Calculate squared Uhlmann fidelity and purity for two supplied single-qubit density matrices. Explicit conventions; no experimental certification.

Evaluate supplied absorption observations under a declared band-gap model with fit-window sensitivity. No universal band-gap or integrated-device performance claim.

Match supplied Raman peak positions by nearest unused reference within an absolute tolerance. No linewidth analysis or unique material identification.
