Abstract
The integration of readout electronics and sensors into a single entity of silicon in monolithic pixel detectors lowers the material budget while simplifying the production procedure compared to the conventional hybrid pixel detector concept. The increasing availability of high-resistivity substrates and high-voltage capabilities in commercial CMOS processes facilitates the application of depleted monolithic active pixel sensors (DMAPS) in modern particle physics experiments. TJ-Monopix2 and LF-Monopix2 chips are the most recent large-scale prototype DMAPS in their respective development line originally designed for the ATLAS Inner Tracker outer layer environment. In this contribution, the latest laboratory characterizations and beam test results of both DMAPS are presented with a special emphasis on performance after irradiation to high fluences.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
