Cell cycle synchronization is of paramount importance for studying cellular properties and biological processes involved in various stages of the cell cycle. Here, we present a microfluidics based approach to synchronize the cell cycle of a primary - cells, human bone marrow-derived mesenchymal stem cells (hMSCs), using inertial forces in spiral microchan-nels. The device operating principle exploits the relationship between the volume (and thus diameter) of a cell and its phase in the cell cycle, in order to fractionate hMSCs populations into synchronized subpopulations enriched in cell cycle fractions of G0/G1, S and G2/M phases.

An automatic detector that finds circular dining plates in chronically recorded images or videos is reported for the study of food intake and obesity. We first detect edges from input images. After a number of processing steps that convert edges into curves, arc filtering and grouping algorithms are applied. Then, convex hulls are identified and the ones that fit the description of ellipses corresponding to dining plates are determined. Our experiments using real-world images indicate that this detector is highly reliable and robust even when the input images contain complex background scenes and the dining plates are severely occluded.
We report the numerical analysis of gradient index (GRIN) lens-based optical coherence tomography imaging probes to derive optimal design parameters. Long and short working distance probes with a small focal spot are ...

According to a study conducted by J. D. Angrist (MIT) and colleagues1 involving 1,600 students at a large Canadian university (the equivalent of an American state university with heavily subsidized tuition), the combination of participation in (a) a scholarship program and (b) academic support services resulted in higher grade achievement and retention for females (but both males and females used support services and peer advising at higher rates), compared to groups of students who participated in either (a) or (b) but not both. A report by the Educational Policy Institute2 lists financial aid as one critical factor that affects the decision to pursue a college degree and success in degree attainment for minorities. This paper reports the progress of a persistence-to-graduation scholarship program funded under the National science Foundation Scholarships (NSF) in science, Technology, engineering, and Mathematics (S-STEM) program. We named our program YES (Young Entrepreneur and Scholar) scholarship program. The goal of YES is to enable academically talented, financially needy students to enter the workforce (Entrepreneurship Path) or to pursue a graduate degree (Research Path) following the completion of a baccalaureate degree in a targeted STEM discipline. This goal is facilitated through scholarships offered by the program to qualified student participants in the last two college years (maturing years - juniors and seniors), a mentorship program (faculty and industry mentors), and enhanced educational opportunities (Distinguished Speaker seminar series, Symposium, learning community). The program continues the efforts of and recruits from another NSF-funded program, science, Technology, engineering, and Mathematics Talent Expansion (STEP) program, which focuses on the first two student college years (early years- freshman and sophomore) and has been successful in retaining STEM students at significantly higher rates than academically similar STEM students at the
