A medical image processing method of determining a fractional flow reserve through a stenosis of a coronary artery from medical image data is disclosed. The medical image data comprises a set of images of a coronary region of a patient. The coronary region includes the stenosis. The method comprises: reconstructing a three dimensional model of a coronary artery tree of the patient from the medical image data; determining stenosis dimensions from the three dimensional model of the coronary artery tree of the patient; simulating blood flow in the three dimensional model of the coronary artery tree of the patient to determine modeled flow rates; using an analytical model depending on the stenosis dimensions to predict a modeled pressure drop over the stenosis from the modeled flow rates; and determining the fractional flow reserve through the stenosis from the modeled pressure drop.

Medical image processing methods and systems

The invention relates generally to cooling matter using laser emission, and in particular, to cooling perovskite materials using laser emission.

Laser cooling of organic-inorganic lead halide perovskites

The present invention relates to a logic gate, comprising a metamaterial surface enhanced Raman scattering (MetaSERS) sensor, comprising (a) alphabetical metamaterials in the form of split ring resonators operating in the wavelength range of from 560 to 2200 nm; and (b) a guanine (G) and thymine (T)-rich oligonucleotide that can, upon presence of potassium cations (K), fold into a G-quadruplex structure, and in presence of Hg, form a T-Hg-T hairpin complex that inhibits or disrupts the G-quadruplex structure formed in presence of K, as well as methods of operating and using such a logic gate.

A method of generating a metamater-operable in the visible-infrared range is provided. The method comprises a) depositing a layer of a conductive material on a substrate; b) forming a layer of electron beam resist on the layer of conductive material; c) patterning the layer of electron beam resist using electron beam lithography to form a patterned substrate; d) depositing a layer of a noble metal on the patterned substrate; and e) removing the resist. A metamaterial operable in the visible-infrared range comprising split-ring resonators having a least line width of about 20 nm to about 40 nm on a substrate is provided. A transparent photonic device or a sensor for chemical or biological sensing comprising the metamaterial is also provided.

Method of generating a metamaterial, and a metamaterial generated thereof

There is provided a laser cooling apparatus including: a laser for providing an emission; a silicon-on-insulator substrate; and a thin film microstructure thermally anchored to the silicon-on-insulator substrate, the thin film microstructure being made from a material selected from either a II-VI binary compound semiconductor or a II-VI tenary compound semiconductor.

Semiconductor optical cryocooler

A method of fabricating an organic field effect transistor (OFET) includes forming at least one OFET structure by ultraviolet (UV) transfer embossing printing, where, in an example embodiment, the method includes providing ink material on at least part of a patterned surface of a mold, where the moldis then contacted on a coating of ultraviolet (UV) curable resin on a substrate so as to insert at least part of the ink material into the resin, the resin is then irradiated with UV light, and the mold is separated from the resin so as to transfer the ink material onto the substrate to form at least one OFET structure.
