\section{Conclusions}
We have surveyed 44 YSOs located near the edges of MIR-identified bubbles in CS(1-0) using the GBT. Our conclusions are:
\begin{itemize}
\item We have detected CS toward 18
sources sources.
\item Using Herschel/HiGal survey data, we calculated CS abundances for these sources to be $\sim$10$^{-7}$ and range between 0.16-9.36
$\times$10$^{-7}$ $\times$10$^{-7}$.
\item Three sources show
non-gaussian non-Gaussian line-profiles with strong emission on the blue-shifted side. We interpret this profile as caused by gas infall onto a protostar.
\item Two of the infall candidates (N62-1 and N90-2) are embedded in infrared dark clouds along the edge of their expanding bubbles. The combination of photometry-based YSO identification, CS-based infall, location inside an IRDC and on the edge of an expanding bubble is strongly suggestive of triggered
star-formation. star formation.
\item Using a two-component model, we estimate that one infall candidate, N117-3, has an average infall speed of 0.31 km/s and a mass infall rate of 2.9 $\times$ 10$^{-5}$ M$_\odot$/yr. These numerical results are consistent with intermediate to massive star-formation.
\item Our interpretation of infall in N62-1, N90-2, and N117-3 assumes that the observed CS emission is optically thick. However, our interpretation of the asymmetric, non-Gaussian line profile in N65-2 is that there are two line-of-sight clouds contributing to the emission. It is possible that a similar mechanism could produce the profiles seen in N62-1, N90-2, and N117-3. Further observations of an optically thin line, for example $^{34}$CS, are needed to distinguish between the two possible interpretations.
