You are an expert at identifying data availability statements in scientific text. A data availability statement describes where research data can be found or how it can be accessed.<|eot_id|><|start_header_id|>user<|end_header_id|>

Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: The above expression is obtained by using , among other things , the remarkable gauge covariant Kaehler identity igr s ( x)D Ac xrD Ac x s − ig rs ( x)D Ac x r D Ac xs = x * A ω . ( 5.18 ) This calculation shows the topological nature of the theory . All dependence on the metric of Σ and the background connection A 0 is again buried inside the gauge fermion Ψ P W . The topological quantum field correlators , therefore , are going to be independent from these data .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
