Abstract: Methods, mediums, and systems for constructing a 3D face model, including Deep Iterative Face Fitting (DIFF) and Recurrent Feature Alignment (ReFA). A processor provides a reference—containing a 3D mesh representing a median face, vertex positions, or surface points—as a template and UV texture mapping pointing the 3D mesh to a 2D UV space; receives input image(s) of a face and extracts geometry/texture features in an image space; extracts features in a UV space; iteratively produces a feature map via visual semantic correlation between UV and image spaces and regress geometry updates, predicting texture maps and comparing features, and inputs the map to an RNN-based neural optimizer of Gated Recurrent Units (GRU) to determine a hidden state. A head pose and/or updated 3D mesh/UV-space position map is output, each pixel in the UV-space map storing a coordinate of a corresponding point in a canonical space of the 3D mesh.

Abstract: Provided is a method for biosynthesis of a protein heterocatenane. The basic structure of a protein precursor sequence of the protein heterocatenane comprises form an N-terminal to a C-terminal: L1-1-X-L1-2-(in situ enzyme cutting site)-L2-1-X-L2-2, wherein the Xs represent entangled motifs for forming dimers, the two Xs can be the same or different, L1-1/L1-2 and L2-1/L2-2 represent two pairs of cyclization motifs that undergo an orthogonal coupling reaction in cellulo, and the two pairs of cyclization motifs can be two orthogonal peptide-protein reactive pairs, or combinations of peptide-protein reactive pairs and split inteins, or two orthogonal split inteins. When the peptide-protein reactive pair and the split intein are combined for use, biosynthesis of branched protein heterocatenanes can be achieved; and when the two orthogonal split inteins are combined for use, the protein heterocatenane having a completely cyclized main chain can be obtained.

Abstract: The present disclosure provides a method of designing and manufacturing a hydraulic valve block based on selective laser melting. The method includes providing a machined hydraulic valve block, determining whether the machined hydraulic valve block needs weight reduction, if the machined hydraulic valve block needs weight reduction, taking reduction of the pressure loss of the flow channel as an optimization goal and optimizing the flow channel of the machined hydraulic valve block to obtain an optimized flow channel structure model, taking reduction of the weight of the hydraulic valve block as an optimization goal and optimizing solid portions of the optimized flow channel structure model by using a topology optimization method to obtain a three-dimensional solid structure model of a hydraulic valve block and printing the three-dimensional solid structure model by using selective laser melting to obtain the hydraulic valve block.

Abstract: Process chamber shields having specially profiled edges exhibit increased lifetime in PVD and CVD deposition chambers. Edge profiling reduces flaking and delamination of materials deposited onto the shields, thereby prolonging shield life, and, consequently, reducing costs associated with deposition. In one embodiment, a shield having an edge portion terminating in a rounded tip, where the tip has high curvature and a small thickness, is provided. In another aspect, a shield having a concave portion connecting with an edge portion, where an upper (inner) surface of the edge portion forms a tangent plane to the upper (inner) concave surface of the concave surface, is provided. In yet another aspect, a shield with a tapered edge portion is provided. Shields, having profiled edges in accordance with these aspects and in accordance with combinations of these aspects, can better support deposited films, particularly films containing compressively stressed materials, such as metal nitrides.

Abstract: A shielding system for a physical vapor deposition (PVD) chamber is disclosed. The PVD chamber includes a pedestal supporting a substrate. The shielding system includes a first annular portion and a second annular portion of a pedestal shield. The first annular portion is attached the pedestal at a first location. The first annular portion is located at or below a plane including the substrate. The second annular portion is attached to the pedestal at a second location that is below the first location. The first annular portion is spaced a predetermined distance from the second annular portion and is electrically isolated from the second annular portion.
