Abstract: The present disclosure provides techniques to reduce or eliminate contaminants in a waveguide resulting from the waveguide fabrication process. A blocking layer is deposited on a grating layer to protect the grating layer from contamination, e.g., via diffusion, from a hardmask layer that is used to pattern the grating layer. Accordingly, the optical gratings resulting from the patterning of the grating layer have little or no contamination from the hardmask layer, thereby increasing the optical performance of the final waveguide product.

Abstract: The disclosure provides a method for treating a subject afflicted with a tumor, e.g., lung cancer, having a high tumor mutation burden (TMB) status comprising administering to the subject an immunotherapy, e.g., an anti-PD-I antibody or antigen-binding portion thereof. The present disclosure also provides a method for identifying a subject suitable for an immunotherapy, e.g., a treatment with an anti-PD-I antibody or antigen-binding portion thereof, comprising measuring a TMB status of a biological sample of the subject.

The dent depth meta-model is utilized to estimate an impact energy to establish a threshold dent depth in the structural configuration. A computer-based simulation is performed with the structural configuration utilizing the impact energy from the dent depth meta-model. At least one design value is determined for the structural configuration based on output data generated from the computer-based simulation.
