Abstract: A PET imaging agent is made, by at first, washing out fluoride ions (F-18) adhered on an ion exchange resin to a reaction vessel with potassium carbonate/Kryptofix 2.2.2 in acetonitrile-water. After processing the first azeotropic distillation with helium while water is removed, the temperature is cooled down. Then, acetonitrile is added to the reaction vessel to be heated up. After processing the second azeotropic distillation with helium while water is removed, the temperature is cooled down and excess water is extracted. A precursor is then added to the reaction vessel to be heated up for processing a fluorination reaction. The reaction mixture obtained after the fluorination reaction is cooled down to be flown through a solid-phase extraction column with waste drained into a waste tank. Then, ethanol is used to wash out a product, i.e. [F-18]FEONM, adsorbed by the column, to be collected in a collection vial.

Abstract: A security monitoring system for a Controller Area Network (CAN) comprises an Electronic Control Unit (ECU) operatively connected to the CAN bus. The ECU is programmed to classify a message read from the CAN bus as either normal or anomalous using an SVM-based classifier with a Radial Basis Function (RBF) kernel. The classifying includes computing a hyperplane curvature parameter ? of the RBF kernel as ?=ƒ(D) where ƒ( ) denotes a function and D denotes CAN bus message density as a function of time. In some such embodiments ?=ƒ(Var(D)) where Var(D) denotes the variance of the CAN bus message density as a function of time. The security monitoring system may be installed in a vehicle (e.g. automobile, truck, watercraft, aircraft) including a vehicle CAN bus, with the ECU operatively connected to the vehicle CAN bus to read messages communicated on the CAN bus.

Abstract: A computing device predicts occurrence of an event or classifies an object using semi-supervised data. A label set defines permissible values for a target variable. A value of the permissible values is defined for a subset of observation vectors. A predefined number of times, a distance matrix is computed that defines a distance value between pairs of observation vectors using a distance function and a converged classification matrix; a number of observation vectors is selected that have minimum values for the distance value; a label is requested and a response is received for each of the selected observation vectors; the value of the target variable is updated for each of the selected observation vectors with the received response; and the value of the target variable is determined again by recomputing the converged classification matrix. The value of the target variable for each observation vector is output to a second dataset.
