Abstract: Aspects of the invention include techniques for intimacy-based masking of three dimensional (3D) face landmarks within a metaverse. A non-limiting example method includes determining a degree of intimacy R between a first user and a second user responsive to a first avatar of the first user being observed by a second avatar of the second user in a virtual environment. An initial set of M landmarks of a feature of the first avatar is determined and N landmarks are randomly selected from M for masking. The N landmarks are replaced with random noise sampled with a unit normal distribution to define a set of noised landmarks X that are then iteratively denoised to define a set of denoised landmarks D. A masked version of the first avatar is presented to the second user by modifying the feature of the first avatar with the set of denoised landmarks D.

Abstract: A large grain quasi-single-crystal film and a manufacturing method thereof are provided. The metal film having the <111> preferred orientation on its surface is subjected to mechanical tensile force to make the arrangement of crystal grains more ordered. The metal film is grown into a film with large crystal grains having an average diameter of over 500 microns by annealing at a temperature below the recrystallization temperature, thereby obtaining a large grain quasi-single-crystal film having the preferred directions of three axes. The large grain quasi-single-crystal film has a <110> preferred orientation along the tensile direction and a <211> preferred orientation along the direction vertical to the tensile force, and maintains a <111> preferred orientation on its top surface. The present invention can be used to produce highly anisotropic large-area quasi-single-crystal films, and can also be applied to grow 2-dimensional materials or develop anisotropic structures.

Abstract: A quasi-single-crystal film and its manufacturing method thereof are provided, in which a metal film having a preferred orientation of <111> on its surface is subjected to a mechanical stretching force, such that the crystal grains thereof are able to form in a much more orderly arrangement, and a quasi-single-crystal film having preferred orientations on three axes can be obtained. The proposed quasi-single-crystal film has preferred orientations of <211> and <110> on its stretching direction and a direction that is perpendicular to the stretching direction, respectively, and retains a preferred orientation of <111> on its surface. By employing the present invention, it is advantageous of manufacturing large-area quasi single crystal films having high anisotropy as well as growing two dimensional materials or developing of other anisotropic feature structures.

Abstract: A supporting rack may include a supporting surface, a base, a side supporting member, a center supporting member and a position adjusting unit. In one embodiment, the side supporting member has two side supporting arms, and an upper end of each side supporting arm is pivotally connected with an upper locking unit on one side of the supporting surface and a lower end thereof is pivotally connected to a corresponding side of the base. More specifically, the lower end of each side supporting arm is also connected to a lower locking unit on the base, which is configured to provide not only a stronger support for the supporting surface, but also lock the lower end of the side supporting arms. Similarly, each side supporting arm can be locked through the upper locking unit at a predetermined position according to the user's preference.
