Abstract: The present disclosure provides a flow battery and a cell stack. The cell stack includes: a first end plate; a second end plate; and at least one cell module arranged between the first end plate and the second end plate. Each cell module includes a first flow channel end plate, a second flow channel end plate arranged opposite to the first flow channel end plate, and single-cell assemblies arranged between the first flow channel end plate and the second flow channel end plate. The single-cell assemblies include at least three hermetically-assembled cell assemblies, the first flow channel end plate is provided with arch-like flow channels, the second flow channel end plate is provided with arch-like flow channels, and each arch-like flow channel is provided with a flow channel aperture in communication with the at least three hermetically-assembled cell assemblies.

Abstract: A synthetic peptide sp4 has an amino acid sequence shown in SEQ ID NO: 1. As the sole effective ingredient in the antitumor efficacy test, it has a significant inhibitory effect on both the tumor volume and tumor weight of human osteosarcoma MG-63 in nude mice and has a significant dose-effect and time-effect relationship. There is no difference between the relative tumor growth rate T/C (%) of sp4 and that of the positive control group of Paclitaxel. The safety of sp4 is that its maximal tolerated dose for intravenous administration is 700 mg/kgBW. Sp4 has clear targets of pharmacological effects, while having efficacy in vivo, it also has an inhibitory effect on tumor telomerase, has an arrest on G1 phase of the tumor cell cycle, and inhibits the high expressions of tumor PD-L1 and CD47. The present disclosure relates to multiple uses of sp4, especially in the preparation of a class of antitumor drugs.

Abstract: A temperature monitoring method of a brake of a freight vehicle based on TBOX is provided, including: determining a weight of the freight vehicle based on OBD data of the freight vehicle collected by the TBOX; inputting the weight, the OBD data, a longitudinal slope in a high-precision map to determine the temperature of the brake of the freight vehicle; setting a temperature warning threshold of the brake based on its performance parameters of the freight vehicle, and determining a first driving state and a second driving state in a front road section with the determined temperature of the brake, and generating a warning signal and a forewarning signal of the freight vehicle. The monitoring method improves accuracy of the brake temperature by introducing altitude variation of the front road section and weight of the freight vehicle, and provides powerful data support for a safe driving.

Abstract: A document transcription application receives an image of a document that comprises structured data. The document transcription application performs optical character recognition upon the image of the document to produce a block of text. The document transcription application applies the block of text to a first machine learning model to determine a heat map for a class of data in the structured data in the image of the document. The document transcription application applies the image of the document and the heat map to a second machine learning model to identify a region of the image of the document representing the class of data. The document transcription application generates, using the identified region and the block of text, a structured data file.
