Abstract: The present invention provides an on-chip integrated cell phone spectrometer and a cell phone. The spectrometer includes: a detection system, including a cell phone lens and a focal plane detector integrated with a Bayer filter; and a spectral filter array, integrated at an edge of the Bayer filter, the spectral filter array including a plurality of filtering channels with different spectral transmittances, each filtering channel corresponding to one or more detector pixels, where the cell phone lens is configured to acquire a reflected light from an object under test, the focal plane detector is configured to acquire an intensity signal of the reflected light, and after different intensity signals corresponding to different filtering channels are obtained, a data processing system performs spectral reconstruction to obtain spectral data of the object under test.

Abstract: A quinoline derivative used for soft tissue sarcoma combination therapy, relating to a use of the quinoline derivative in combination with a second therapeutic drug to treat soft tissue sarcoma, wherein the second therapeutic drug may be a chemotherapy drug, a small molecule targeted anti-tumour drug or an immunotherapy drug. The chemical name of the quinoline derivative compound I is 1-[[[4-(4-fluoro-2-methyl-1H-indol-5-yl)oxy-6-methoxyquinolin-7-yl]oxy]methyl]cyclopropylamine.

Abstract: Embodiments of the invention provide systems and methods for searching for elements of a document based on an order priority of attributes of a query expression. According to one embodiment, a method of searching a plurality of objects of a document, such as elements of a DOM document, can comprise generating a query expression with attributes related to a target object of the document. For example, the expression can comprise an XPath expression. The attributes of the query expression can be parsed into one or more attribute groups, each comprising at least one attribute, based on logical operators between the attributes. Each one or more attribute groups of each expression can be weighted and a search can be performed for the target object in the document based on the weighted one or more attribute groups of the query expression.
