  • Publication number: 20170298415
    Abstract: A method is provided for generating single-stranded DNA circles from a biological sample. The method comprises the steps of: treating the biological sample with an extractant to release nucleic acids, thereby forming a sample mixture; neutralizing the extractant; denaturing the released nucleic acids to generate single-stranded nucleic acids; and contacting the single-stranded nucleic acids with a ligase that is capable of template-independent, intramolecular ligation of single-stranded DNA to generate the single-stranded DNA circles. All the steps of the method are performed without any intermediate nucleic acid isolation or nucleic acid purification. The single-stranded DNA circles may be amplified and further analyzed. Also provided is a kit which comprises compositions for carrying out the novel methods.

  • Patent number: 9790109
    Abstract: The present invention has the technical effect of disinfecting an EDI device of a water purification system. The present invention may be applied to an EDI device having an internal chamber comprising ion exchange components. The internal chamber may also comprise a plurality of ion selective membranes positioned between the anode and the cathode compartments. As illustrated and described herein, embodiments of the present invention seek to sanitize the EDI device without sanitization chemicals or a water supply. Embodiments of the present invention disinfect the EDI device by applying electrical power. Here an electrical supply device heats the EDI device, through resistive heating of the internal chambers, to a sanitization temperature. The resistive heating is a result of ionic movement through the internal chamber. The friction that is created through the ionic movement increases the temperature within the internal chamber.

  • Patent number: 9788009
    Abstract: A coding efficiency increase is achieved by using a common signalization within the bitstream with regard to activation of merging and activation of the skip mode. One possible state of one or more syntax elements within the bitstream may signalize for a current sample set of a picture that the sample set is to be merged and has no prediction residual encoded and inserted into the bitstream. A common flag may signalize whether the coding parameters associated with a current sample set are to be set according to a merge candidate or to be retrieved from the bitstream, and whether the current sample set of the picture is to be reconstructed based on a prediction signal depending on the coding parameters associated with the current sample set, without any residual data, or to be reconstructed by refining the prediction signal depending on the coding parameters associated with the current sample set by means of residual data within the bitstream.
