Abstract: A technique is described for the application of three-dimensional (3D) relief to a substrate such as a ceramic tile using digital inkjet technology. A computer system receives information defining a relief pattern for forming the 3D relief using a digital inkjet printer. From the information, a feature vector is extracted comprising one or more features describing the 3D relief. A machine learning model is used to generate control commands based on the feature vector. The machine learning model is trained to generate the control commands to configure the digital inkjet printer to apply binder ink to a first region of a surface of the substrate. The applied binder ink is configured to form a protective layer over the first region of the surface of the substrate. The digital inkjet printer is configured to apply solvent ink to the surface of the substrate.

Abstract: The systems, devices, and methods presented herein use a blood pump to obtain measurements of cardiac function. The system can quantify the functioning of the native heart by measuring certain parameters/signals such as aortic pressure or motor current, then calculate and display one or more cardiac parameters and heart function parameters, such as left ventricular pressure, left ventricular end diastolic pressure, or cardiac power output. These parameters provide valuable information to a user regarding current cardiac function, as well as positioning and function of the blood pump. In some embodiments, the system can act as a diagnostic and therapeutic tool.

Abstract: A new and distinct cultivar of Vaccinium plant named ‘DW18-04’ is disclosed, characterized by an upright and spreading plant habit, vigorous growth and semi-deciduous habit in Florida. Fruit is very firm, with an average firmness of 333 g/mm. The new variety shows tolerance for wet soil conditions. Fruit yield is exceptionally high, with fruit ripening early, with first harvest in mid-March in Central Florida. Fruit is globose, 18 to 25 mm in diameter with an attractive waxy coating. The new variety is a Vaccinium, and is normally used for commercial fruit production.
