Fetch one federal R&D award as a normalized record with its full abstract. Give the award identifier and its source (NIH project number, NSF award id, or SBIR award) and get the title, complete abstract, agency, amount, dates, principal investigators, organization and technology terms, plus for NIH the linked publication PubMed ids. Cheap single-record pull.
Received R&D-funding profile of a company, organization or principal investigator, fused from NIH RePORTER, NSF and SBIR/STTR public records. Give a company or organization or PI name and get every federal research award it received with amounts, agencies, years, tech focus and abstracts, plus computed aggregates: total non-dilutive funding, breakdown by agency and by year, technology clusters, and active-award count.
Find federally funded R&D projects by technology topic across NIH RePORTER and NSF. Give a keyword such as a mechanism, disease area or technology and get a ranked list of funded projects with the recipient organization, principal investigator, agency, amount, year and abstract, for competitor-landscape mapping and lead generation. Bounded scan with a coverage note.
Area (Heron's formula), perimeter and interior angles of a triangle from its three side lengths. Sides that violate the triangle inequality are rejected as a clean 400.
Area (shoelace formula), perimeter and centroid of a simple polygon given its vertices in order. Vertices are treated as a closed ring (last connects to first).
Academic letter grade with red-pen marginalia for anything. $0.01 USDC.
Computes all pair distances and a single-parameter Lennard-Jones 12-6 potential using caller-supplied epsilon and sigma. It does not perform quantum chemistry, infer element-specific force fields, relax geometry, model bonds or predict experimental molecular behavior.
Treats a caller-supplied odd-length bit word as a classical repetition code, majority-decodes one logical bit, and reports the corrected word and adjacent XOR syndrome. This narrow demonstration is not a surface-code simulation and does not model coherent quantum errors, measurements or fault-tolerant thresholds.
Converts ++, +−, −+ and −− counts into a correlation for each of AB, AB′, A′B and A′B′, then computes S = E(AB) + E(AB′) + E(A′B) − E(A′B′). A value above the classical bound in supplied data does not by itself demonstrate entanglement or close detection, locality, sampling or significance loopholes.
Backyard livestock & homesteading guide — how to raise chickens, goats, rabbits, bees, ducks, pigs, or sheep for eggs, milk, meat, and honey: space, startup cost, breeds, and yield by climate. For homesteading agents.
