Establishing a strong STEM (science, technology, engineering and mathematics) identity at Boise State University, a metropolitan campus with approximately 3,655 undergraduate STEM students and a total undergraduate enrollment of approximately 19,042 (16,136 FTE) has been an important step toward creating a climate conducive to facilitating fundamental change. Examples of such change include building collaborations among faculty within and across departments, establishing the identity of students as part of a community beyond their chosen major, improving the efficiency and effectiveness of university systems, and perhaps most importantly, developing a framework to think deliberately about ways to effect change. This paper is …

Multi-channel photo-acoustic and laser ultrasonic waves are used to sense the characteristics of proxies for healthy and diseased vessels. The acquisition system is non-contacting and non-invasive with a pulsed laser source and a laser vibrometer detector. As the wave signatures of our targets are typically low in amplitude, we exploit multi-channel acquisition and processing techniques. These are commonly used in seismology to improve the signal-to-noise ratio of data. We identify vessel proxies with a diameter on the order of 1 mm, at a depth of 18 mm. Variations in scattered and photo-acoustic signatures are related to differences in vessel wall …
