We consider the mathematical model presented in [11], where a Fredholm integral equation of the first kind for the Gr\\\"uneisen parameter was derived. For the numerical solution of the integral equation we consider a Galerkin type method.","authors_text":"Leonidas Mindrinos, Otmar Scherzer, Peter Elbau","cross_cats":["math-ph","math.MP"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.AP","submitted_at":"2017-09-01T09:21:12Z","title":"Quantitative reconstructions in multi-modal photoacoustic and optical coherence tomography imaging"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1709.00207","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:5ea3e592fedf9063af9cca18e950c87422117bde0c1a8af881c63cefdecfd7e0","target":"record","created_at":"2026-05-18T00:02:49Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"543fab90b9127c2866d078f6da010bfe0f979eb555c5baad6875a184c68d5718","cross_cats_sorted":["math-ph","math.MP"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"math.AP","submitted_at":"2017-09-01T09:21:12Z","title_canon_sha256":"bee16405e5dcd76c03111830c3fc51b7e6daf50a5489ab01d19b2122ecb82d2c"},"schema_version":"1.0","source":{"id":"1709.00207","kind":"arxiv","version":1}},"canonical_sha256":"147d32b6b4d4f7c2f80d14869fbc9d53641041ff4b04358c82d9e85cfa703021","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"147d32b6b4d4f7c2f80d14869fbc9d53641041ff4b04358c82d9e85cfa703021","first_computed_at":"2026-05-18T00:02:49.787802Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:02:49.787802Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kcYtv1sjsgNK0aUxupIKKAcDuhfKGrBFPnWJBoG4QnRj0GmEQoiResmN4fwgMTwhwOLcFlhw7y1CbN/4EKCNDw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:02:49.788365Z","signed_message":"canonical_sha256_bytes"},"source_id":"1709.00207","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5ea3e592fedf9063af9cca18e950c87422117bde0c1a8af881c63cefdecfd7e0","sha256:618d2efb868de861aea0162247c9b8132efa7c07fe687ed9b4ddfb1b3e41e068"],"state_sha256":"f48cec70c59c897dcca3f1622e15b0973cd2077352e3ac71e476bf92a0cca610"}
