In this work, we demonstrate a novel rotary microsystem for simple, rapid and automatic influenza viral RNA purification. The microdevice consists of a silica sol-gel matrix for RNA capture, and three reservoirs for a RNA sample (R(S)), a washing solution (R(W)) and an elution buffer (R(E)) that were connected with different dimensional microfluidic… (More)
To explore small unmanned aerial vehicle (UAV) remote sensing identifying technology for horticultural crop diseases, and to combine it with small UAV spraying, the peach leaf blade was taken as material, the peach shot-hole disease was taken as object for spectral capture, and the intellectualized identifying and precision control system for horticultural… (More)
PURPOSE We aim to fabricate a thermoplastic poly(methylmethacrylate) (PMMA) Lab-on-a-Chip device to perform continuous- flow polymerase chain reactions (PCRs) for rapid molecular detection of foodborne pathogen bacteria. METHODS A miniaturized plastic device was fabricated by utilizing PMMA substrates mediated by poly(dimethylsiloxane) interfacial… (More)
We introduce the epidemic quasimetric on graphs and study its behavior with respect to clustering techniques. In particular we compare its behavior to known objects such as the graph distance, effective resistance, and modulus of curve families.
