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: (i) To modify the Adaptive Data Rate algorithm to consider congestion statuses of **data** rates during the **data** rate optimization process to improve the collision probabilities of end devices' traffic in Long-Range Wide Area Networks. (ii) To use simulations to evaluate the effectiveness of the proposed modifications to the Adaptive Data Rate algorithm in mitigating the occurrence of traffic collisions in Long-Range Wide Area Networks.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
