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: One of the foremost goals of investigation of BP in the QH regime is the QHE states , as the comparable energy scales of E c and E z are expected to facilitate the observation of even - denominator states 59,60 , thus providing another much - needed playground to study this very intriguing state for topological computing . Moreover , BP 's anisotropic crystal lattice may shed light on the anisotropic FQHE states observed in GaAs systems [ 3][4][5][6][7][8][9][10][11][12][13][14 ] . Indeed , at very high magnetic fields , we observe a FQHE state in device 2 . Fig . 4a plots the R xx and R xy line traces vs V bg at B = 45 T. A well - defined minimum in R xx appears at V bg~ -25 V ( indicated by black arrows ) , accompanied by a plateau in R xy quantized to ~19 kΩ ( 3/4 h / e 2 ) . Both features move with n and B , as indicated by the dashed lines in Fig . 4b , and disappear at B~ 41 T ( Fig .   4b ) . We thus attribute this feature to a fraction QH state . For better visualization , we replot the same data in Fig . 4c , where red , blue and orange data points represent the center of the ν=-1 , -2 and -3 QH plateaus , respectively , and the black the observed fractional state . The dashed lines extrapolated to B=0 , where they converge at the band edge . From their slopes , the filling factor of the fractional state is estimated to be -4/3 , in agreement with the plateau value R xy .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
