Using techniques similar to those involved in DNA fingerprinting, they then looked for the presence of antibiotic-resistant genes - and found these in high concentrations.

他们运用类似DNA指纹识别的技术，寻找抗药性的基因的存在，并在高浓度季铵盐存在下找到了它们。

The waves give us a biomarker to test for the presence of these bacteria, even when we can’t detect them with classical techniques like PCR.

这个电磁信号可以作为检测细菌存在与否的生理标记，尤其是当传统的检测方法，比如PCR不起作用的时候。

The mathematical sciences prize was awarded to David L. Donoho for his "contributions to modern mathematical statistics and in particular the development of optimal algorithms for statistical estimation in the presence of noise and of efficient techniques for sparse representation and recovery in large data-sets, " the committee said.
