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: Interest in the LL was greatly intensified by Anderson's proposal [127] that the ARPES lineshapes and certain other properties of the superconducting cuprates signaled in a general way the possibility of LL behavior in quasi 2-d systems, and by pioneering PES studies [128][129][130] of quasi-1-d metals that found power law onsets to EF rather than a Fermi edge. A complication for interpreting the PES **data** is that below a transition temperature TCDW the quasi-1-d metals studied display static charge density wave (CDW) formation which gaps the quasi-1-d FS and produces an insulator. Especially in 1-d, strong CDW fluctuations involving electron-phonon interactions above TCDW can cause the PES lineshape to have NFL behavior that mimics that of the LL, in particular that there can be a pseudogap [131][132][133] such that the weight at EF is greatly suppressed. This situation has motivated ARPES activity [17] on low-dimensional non-cuprate materials with the intent of elucidating CDW behavior, of searching for a paradigm having the distinctive features of the LL lineshape, and of seeing connections to cuprate spectra. The finding of the FL paradigm TiTe2 discussed in section 3.2 above was part of this general program, which has now progressed also to success with the other two goals, as described next.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
