Estimation method for state of charge of battery
The invention provides an estimation method for state of charge (SOC) of battery. A reference SOC is inquired from a look-up table based on a voltage of battery detected. A voltage threshold is subtracted from the voltage of battery to obtain a voltage difference. A current SOC or the reference SOC is divided by the voltage difference to obtain a first slope or a second slope. The first slope is divided by the second slope to obtain an adjustment ratio. An electric charge capacity for charging the battery is counted by a coulomb counting method to obtain a count capacity of discharging that is multiplied by the adjustment ratio to obtain an adjustment value. The adjustment value is subtracted from a previously recorded remaining capacity to obtain a new remaining capacity. The new remaining capacity is divided by a full charge capacity to estimate a new SOC of battery. |

Protecting motion sensors from acoustic injection attack
Cyber-physical systems depend on sensors to make automated decisions. Resonant acoustic injection attacks are already known to cause malfunctions by disabling MEMS-based gyroscopes. However, an open question remains on how to move beyond denial of service attacks to achieve full adversarial control of sensor outputs. This work investigates how analog acoustic injection attacks can damage the digital integrity of a popular type of sensor: the capacitive MEMS accelerometer. Spoofing such sensors with intentional acoustic interference enables an out-of-spec pathway for attackers to deliver chosen digital values to microprocessors and embedded systems that blindly trust the unvalidated integrity of sensor outputs. Two software-based solutions are presented for mitigating acoustic interference with output of a MEMS accelerometer and other types of motion sensors. |

The miR-10a-5p and/or miR-10b-5p depleted or blocked populations of RNA can also be used in global gene expression analysis protocols, including next generation sequencing. The kit comprises oligonucleotide probes comprising a nucleotide sequence that is the complement to a nucleotide sequence of the miR-10a-5p and/or oligonucleotide probes comprising a nucleotide sequence that is the complement to a nucleotide sequence of miR-10b-5p. |

Method of producing saccharified solution from used absorbent article
A simple method is provided for producing a saccharified solution from a used absorbent article such as a used diaper. In order to produce a saccharified solution from a used absorbent article comprising a non-cellulosic liquid permeable surface material and an absorbent body that contains pulp fibers, the used absorbent article is immersed, without first being decomposed, in a saccharifying enzyme solution containing cellulase. The pulp fibers in the used absorbent article are saccharified by the cellulase, producing a saccharified solution. The produced saccharified solution is exuded out of the used absorbent article through the liquid permeable surface material, so it is possible to easily separate and recover the saccharified solution from the used absorbent article while maintaining the outer shape. |

Nucleotide sequence and application thereof in enhancing plant pest resistance
A gene RNAi vector is constructed with a V-ATPase subunit E gene fragment, a COO2 gene fragment, or a combination of the V-ATPase subunit E gene fragment and the COO2 gene fragment, then transferred into a plant, and expressed in the plant to produce dsRNA of the V-ATPase subunit E gene, the COO2 gene, or the combination of the V-ATPase subunit E gene and the COO2 double gene, and therefore the aphid growth is suppressed, and the plant is enhanced in pest resistance. |

Pig with a genetically modified CD163 gene resistant to PRRSv
The present disclosure relates methods and compositions useful for prevention of porcine reproductive and respiratory syndrome virus (PRRSv) in animals, including animals of the species Sus scrofa. The present teachings relate to swine wherein at least one allele of a CD163 gene has been inactivated, and to specific methods and nucleic acid sequences used in gene editing to inactivate the CD163 gene. Swine wherein both alleles of the CD163 gene are inactivated are resistant to porcine reproductive and respiratory syndrome virus (PRRSv). Elite lines comprising homozygous CD163 edited genes retain their superior properties. |
