[1] [2] The technique induces tissue remodeling [3] and production of new collagen and elastin. [4] [5] The process provides an alternative to facelift [6] and other cosmetic surgeries. By manipulating skin cooling during treatment, RF can also be used for heating and reduction of fat.
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 ...
Slit lamp photograph of posterior capsular opacification visible a few months after implantation of intraocular lens in eye, seen on retroillumination. Nd:YAG lasers are used in ophthalmology to correct posterior capsular opacification, [6] after cataract surgery, for peripheral iridotomy in patients with chronic [7] and acute angle-closure glaucoma, [8] where it has largely superseded ...
In the case of large format, 4 x 5 inch films can record approximately 298.7 million pixels, and 1,200 million pixels in the case of 8 x 10 inch film. However, as with a digital system, poor optical quality of lenses will decrease the resolving potential of a film emulsion.

Four-dimensional computed tomography (4DCT) is a type of CT scanning which records multiple images over time. It allows playback of the scan as a video, so that physiological processes can be observed and internal movement can be tracked.
The name 4D STEM is common in literature, however it is known by other names: 4D STEM EELS, ND STEM (N- since the number of dimensions could be higher than 4), position resolved diffraction (PRD), spatial resolved diffractometry, momentum-resolved STEM, "nanobeam precision electron diffraction", scanning electron nano diffraction (SEND ...
[2] On 6 May 2014, Cine Colombia opened its first MX4D theater, labeled as Dinamix 4D, in Barranquilla, Colombia at the Centro Comercial Buenavista mall, with the release of The Amazing Spider-Man 2. [3] [4] On 26 March 2014, MediaMation entered an agreement with Santa Rosa Entertainment to install the first MX4D systems in the United States.
