Abstract: The present disclosure generally relates to spin-orbit torque (SOT) devices comprising a bismuth antimony (BiSb) layer. The SOT devices further comprise one or more GexNiFe layers, where at least one GexNiFe layer is disposed in contact with the BiSb layer. The GexNiFe layer has a thickness less than or equal to about 15 ? when used as an interlayer on top of the BiSb layer or less than or equal to 40 ? when used as a buffer layer underneath the BiSb.

The previous or past milk-based fertilizers have had poor efficacy obtained due to the high fat content of these milk sources due to using too much milk, or rather too much fat in the milk, since the bacteria in the composition will spoil and result in a foul odor, poor growth, and poor crop yield. This fertilizer composition contains a nutrient ingredient, which is the de-fatted milk, as a liquid or dry product, and are utilized between 10 percent weight and 95 percent weight plus uses the coal dust and soluble coal dust as a less expensive stabilizer and chelator as well as other minerals for Nitrogen-Phosphorus-Potassium utilization.

Abstract: The present disclosure generally relates to spin-orbit torque (SOT) magnetic tunnel junction (MTJ) devices comprising a doped bismuth antimony (BiSbE) layer having a (012) orientation. The devices may include magnetic write heads, read heads, or MRAM devices. The dopant in the BiSbE layer enhances the (012) orientation. The BiSbE layer may be formed on a texturing layer to ensure the (012) orientation, and a migration barrier may be formed over the BiSbE layer to ensure the antimony does not migrate through the structure and contaminate other layers. A buffer layer and interlayer may also be present. The buffer layer and the interlayer may each independently be a single layer of material or a multilayer of material. The buffer layer and the interlayer inhibit antimony (Sb) migration within the doped BiSbE layer and enhance uniformity of the doped BiSbE layer while further promoting the (012) orientation of the doped BiSbE layer.

Abstract: An optical coherence tomography (OCT) unit provides a mechanism/method for automatic artery and vein identification. The method may be embodied by specialized algorithm or by a machine learning model, such as a support vector machine or neural network. The present method may identify a vascular configuration that forms a vortex structure in the deep capillary plexus (DCP) of an OCT-based (e.g., OCTA) image of a retina. The identified vortex may then be designated a vein, and other vascular structures from other plexuses, such as from the superficial vascular plexus (SVP), that connect to the identified vortex structure are likewise designated veins. Additional criteria, some based on the vein designations, may be used to identify arteries.
