  • Publication number: 20250230573
    Abstract: There are provided a colloidal crystal having a four-fold symmetric pattern and capable of stably existing even in a geometrically unconstrained space, and a method for producing the same. The colloidal crystal of the present invention exists in a geometrically unconstrained space and has a four-fold symmetric pattern. The colloidal crystal of the present invention can be produced by filling a dispersion of colloidal particles between a substrate 1 and an opposed plate 2 facing the substrate 1 to precipitate a charged colloidal crystal having a four-fold symmetric pattern (crystallization step S1); and electrostatically adsorbing and immobilizing, onto the substrate 1, the charged colloidal crystal having a four-fold symmetric pattern (immobilization step S2).

  • Patent number: 12347881
    Abstract: A battery-module protection structure is configured to protect a battery module accommodated within a vehicle frame of a vehicle from an external impact. The battery-module protection structure includes a rail disposed within the vehicle frame, a pedestal securing the battery module and secured to the rail by using a securing member, and the vehicle frame serving as a housing of the battery module. The pedestal is configured such that, in a case where the vehicle receives the external impact and the securing member breaks, the pedestal moves in an inner direction of the vehicle along the rail while securing the battery module.

  • Publication number: 20250156993
    Abstract: An approach is provided for accelerated flood modeling. Using a down-sampling neural network, a low-resolution elevation map is generated from a high-resolution elevation map. Using a partial differential equation (PDE) model, a low-resolution water depth map is generated from the low-resolution elevation map and one or more boundary conditions. Using an up-sampling neural network, a high-resolution water depth map is generated from the low-resolution water depth map. The down-sampling and up-sampling neural networks are trained by minimizing a loss between the generated high-resolution water depth map and ground truth data generated by the PDE model using the high-resolution elevation map as direct input and without using the low-resolution elevation map.
