Abstract: Methods for depositing amorphous silicon films via physical vapor deposition processes are disclosed. In some embodiments, a method of depositing amorphous silicon in a physical vapor deposition (PVD) process chamber includes (a) depositing an amorphous silicon layer atop a surface of a substrate disposed on a substrate support via a physical vapor deposition process, in the meanwhile amorphous silicon is also deposited atop components within the PVD process chamber; and depositing a glue layer atop the amorphous silicon deposited on the components. The glue layer can be a silicon compound. The silicon compound can be a compound of silicon with one or more of carbon, nitrogen, or oxygen. In some embodiments, the silicon compound is SiC, SiN, SiO, SiCN, or SiON.

Abstract: The present disclosure provides a multi-factor quantitative analysis method for deformation of a neighborhood tunnel. The method includes the following steps: analyzing monitoring data generated at a tunnel site; simulating collapse occurring at a shallow buried section of a tunnel; determining the degree of influence of each factor on the tunnel and a stratum; and determining quantitative influence of each factor on tunnel deformation. The present disclosure can not only provide an accurate theoretical basis for the construction of the shallow buried section of the small-distance tunnel, but also guarantee safety and cost saving during tunnel construction.

Abstract: A system and method for proximate vehicle intention prediction for autonomous vehicles are disclosed. A particular embodiment is configured to: receive perception data associated with a host vehicle; extract features from the perception data to detect a proximate vehicle in the vicinity of the host vehicle; generate a trajectory of the detected proximate vehicle based on the perception data; use a trained intention prediction model to generate a predicted intention of the detected proximate vehicle based on the perception data and the trajectory of the detected proximate vehicle; use the predicted intention of the detected proximate vehicle to generate a predicted trajectory of the detected proximate vehicle; and output the predicted intention and predicted trajectory for the detected proximate vehicle to another subsystem.

Abstract: The present disclosure provides a pH-sensitive membranolytic polymer material and a preparation method and application thereof. The pH-sensitive membranolytic polymer material has the structure shown in Formula (I). At normal physiological pH, the polymer material is hydrophobic neutral, and can be self-assembled into PEG coated nanoparticles with weak interaction with cell membrane; when the pH decreases, the polymer material can be protonated to form an amphiphilic structure consisting of hydrophobic domain and cationic domain, which has strong interaction with the cell membrane and strong membranolytic activity, so the polymer material can kill tumor cells or bacteria efficiently and selectively.
