  • Publication number: 20160026759
    Abstract: A method for detecting a chromosomal aneuploidy relating to a target nucleic acid region includes the following steps. A reference database is obtained. At least one normalizing factor is determined based on the reference database. A cutoff value is determined based on the reference database. A biological sample under test is sequenced by the sequencing platform to obtain a number of target reads of the biological sample under test. The target reads of the biological sample under test originate from the target nucleic acid region. The number of the target reads of the biological sample under test is normalized by the normalizing factor and then is compared with the cutoff value.

  • Publication number: 20110057616
    Abstract: A battery charging circuit includes a power input unit for supplying power to charging units and a control module. Each charging unit includes a connecting port for connecting one battery, an electromagnetic coil and a switch module connected between the connecting port and the electromagnetic coil. The connecting ports are series-connected with one another. The control module is used for monitoring the voltage of the batteries and then controlling a work state of the switch modules by means of comparing a voltage variance between any two of the batteries with a specific data set in the control module so as to make the battery with a greatest voltage discharged to produce a discharge current for secondarily charging the other batteries by means of the electromagnetic coils when the voltage variance is greater than the specific data.
