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: We collectively refer to observations and actions , as well as auxiliary integers and reals generated during computation , as atoms . Our language considers two kinds of data : atoms and sequences of atoms ( including histories ) . We assume a finite set of basic operators over atoms that is rich enough to capture all common operations on observations and actions . Figure 1 shows the syntax of this language . The nonterminals E and α represent expressions that evaluate to atoms and histories , respectively . We sketch the semantics of the various language constructs below .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
