    Abstract: An example system includes an input channel having a first end and a second end to receive particles through the first end, a separation chamber, at least two output channels, and an integrated pump to facilitate flow through the separation chamber. The separation chamber is in fluid communication with the second end of the input channel. The separation chamber has a passive separation structure, the passive separation structure including an array of columns spaced apart to facilitate separation of particles in a flow based on a size of the particles. Each output channel is in fluid communication with the separation chamber to receive separated particles. The integrated pump is positioned within at least one of the input channel or one of the at least two output channels.

    Abstract: Examples include polymerase chain reaction (PCR) devices. Example PCR devices comprise a fluid input, a fluid output, and a set of microfluidic channels that fluidly connect the fluid input and the fluid output. Each microfluidic channel comprises a reaction chamber, and examples further comprise at least one heating element, where the at least one heating element is positioned in the reaction chamber of each microfluidic channel. The at least one heating element is to heat fluid in the reaction chamber of each fluid channel, and the at least one heating element is to pump fluid to the reaction chamber and from the reaction chamber of each microfluidic channel.

    Abstract: A seismic system includes a wireless sensor node. The wireless sensor node includes a global positioning system (GPS) device to receive a GPS time value at an interval; a temperature sensor to measure temperature; an oscillator to measure time; and a memory to store the GPS time value, the temperature, and the oscillator time. The wireless sensor node also includes a processor to determine a rate of temperature change during the interval, and to dynamically update the interval to receive the GPS time value from the GPS device, based on the rate of temperature change.
