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

Text: the authors confirm that all data underlying the findings are fully available without restriction. the lorenz attractor is a simulated signal, it is a supplementary file and simulated based on the information shown in the plos one paper (lorenz_original.txt). the sunspot signal can be downloaded from the following website: http://www.sidc.be/silso/datafiles. the signal is also a supplementary file (sunspot.txt). the mean value of the ae index can be downloaded from: http://www.ngdc.noaa.gov/docucomp/page?xml=noaa/nesdis/ngdc/stp/indices/iso/xml/g00584.xml&view=getdataview&header=none. the mean value of the ae index is also included as a supplementary file(mae78_original.txt). the heat signal is downloaded from http://www.noaanews.noaa.gov/stories2013/20130806_stateoftheclimate.html. the signal is included as well, as a supplementary file (heatwave.txt).<|eot_id|><|start_header_id|>assistant<|end_header_id|>
