Abstract: A computer-implemented method for meshing a model of a physical electro-magnetic assembly is disclosed. The method includes separating the base mesh of the model into two domains and freezing the boundary between these domains. Each domain is then sent for mesh refinement by separate computer processors. Each computer processor generates a refined mesh of the respective domain without communication between processors. Two-way boundary mesh mapping is then performed, resulting in a global conformal mesh. Surface recovery and identity assignment are then performed by separate computer processors in parallel for each domain, without communication between processors. Related apparatus, systems, techniques, methods and articles are also described.

Abstract: A method for labeling an image object and a circuit system are provided. In the method, an object classification method is used to segment an image into one or more regions. Each of the regions can be classified into one classification assigned with a classification label. A depth estimation method is used to estimate a depth of each pixel of the image. Whether or not the depth of the pixel matches the classification of the region to which the pixel belongs is determined. When the depth of the pixel matches the classification of the region, a post-processing process is performed on the image based on weights assigned to the regions according to the classification label of the region. Conversely, when the depth of the pixel does not match the classification of the region, the pixel is regarded as noise that does not require the post-processing process.

Abstract: The present invention describes novel maytansinoid and ansamitosin derivatives and methods for preparing payloads thereof bearing a linker with a functional group for conjugation to cell binding agents to generate cytotoxic drug conjugates. The present invention further relates to antibody drug conjugates conjugated to tumor associated antigen (TAA) antibody, preparation methods, pharmaceutical compositions and uses thereof for the treatment of cancer. The maytansinoid drug linker derivative payloads show increased solubility with decreased aggregation rate compared SMCC-DM1. An antibody drug conjugate containing a maytansinoid drug linker derivative payload and an anti-T rop-2 antibody (e.g., anti-T rop-2-BI-P203) was more or equally potent against Trop-2 high expressing tumors as compared to anti-T rop-2-SMCC-DM 1 or anti-T rop-2-vc-MMAE ADCs, with less effect on low or no antigen expressing cells, suggesting an increased therapeutic window.
