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: With a proper definition of energy in hand , in the third section we consider a large class of time symmetric initial data generalizing the form of solutions considered by [ 9 ] . The fourth section describes some particular negative energy solutions , and the fifth section discusses the time evolution of this data . We point out that while bubbles such as ours and those of [ 9 ] may become large , as long as the standard boundary conditions are preserved they never reach infinity . We conclude with a discussion of some open problems for the gravitational theory and with regards to the AdS - CFT conjecture .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
