Stereolithography is a 3D-printing technique that uses photopolymerization to bind substrate that has been laid layer upon layer, creating a polymeric network. As opposed to fused-deposition modeling, where the extruded material hardens immediately to form layers, 4D printing is fundamentally based in stereolithography, where in most cases ultraviolet light is used to cure the layered ...
4D scanning transmission electron microscopy (4D STEM) is a subset of scanning transmission electron microscopy (STEM) which utilizes a pixelated electron detector to capture a convergent beam electron diffraction (CBED) pattern at each scan location. This technique captures a 2 dimensional reciprocal space image associated with each scan point ...
Initially, Cinema 4D was developed for Amiga computers in the early 1990s, and the first three versions of the program were available exclusively for that platform. With v4, however, Maxon began to develop the application for Windows and Macintosh computers as well, citing the wish to reach a wider audience and the growing instability of the ...
WASHINGTON (Reuters) -A U.S. Justice Department watchdog report released on Thursday debunked claims by far-right conspiracy theorists who falsely alleged that FBI operatives were secretly ...
The 4D is the first complete cinema camera integrated into the Ronin series. [28] The design merges DJI's gimbal technology onto a camera body with an iso-elastic Z-axis arm. [29] The 4D also debuted DJI's optional LiDAR radar system [30] for focusing and tracking objects on screen. [31] Both the 6K and 8K versions were announced on October 20 ...
It is sometimes referred to as "4D Gaussian splatting"; however, this naming convention implies the use of 4D Gaussian primitives (parameterized by a 4×4 mean and a 4×4 covariance matrix). Most work in this area still employs 3D Gaussian primitives, applying temporal constraints as an extra parameter of optimization.
The Fed slashed its benchmark rate by another quarter point on Wednesday, yet you can still lock in a certificate of deposit with guaranteed returns of up to 4.27% APY on terms of 12 months or ...
Many retailers, grocery stores and pharmacies will be open on New Year’s Eve and New Year’s Day, though some have modified hours. (Ash Ponders/Bloomberg/Getty Images/File)
