Connecticut College is a private liberal arts college located in New London, Connecticut. Founded in 1911, the mission of the college is to "educate students to put the liberal arts into action as citizens in a global society," and the College's fourth strategic plan also introduced a set of values statements indicating its commitments to Academic Excellence; Diversity, Equity, and Shared Governance; Education of the Entire Person; Adherence to Common Ethical and Moral Standards; Community Service and Global Citizenship; and Environmental Stewardship. Connecticut College is a primarily residential, four-year undergraduate institution, with nearly all of its approximately 1,900 students living on campus. Students choose courses from 41 majors including an interdisciplinary, self-designed major.Connecticut College was founded as "Connecticut College for Women", in response to Wesleyan University closing its doors to women in 1909; the college shortened its name to "Connecticut College" in 1969 when it began admitting men.The College has been continuously accredited since 1932 by the New England Association of Schools and Colleges. It is a member of the New England Small College Athletic Conference .Forbes ranked Connecticut College 84th in its 2014 overall list, 45th in the Northeast and 70th among private colleges. U.S. News & World Report ranked the school 45th among the top liberal arts colleges in 2014. Wikipedia.

A new analytical tool for determining the optimum frequency for a micromixing strategy to mix two fluids across their interface is presented. The frequency dependence of the flux is characterized in terms of a Fourier transform related to the apparatus geometry. Illustrative microfluidic mixing examples based on electromagnetic forcing and fluid pumping strategies are presented. © 2010 The American Physical Society. Source

Stems that develop secondary vascular tissue (i.e. xylem and phloem derived from the vascular cambium) have unique demands on transport owing to their mass and longevity. Transport of water and assimilates must occur over long distances, while the increasing physical separation of xylem and phloem requires radial transport. Developing secondary tissue is itself a strong sink positioned between xylem and phloem along the entire length of the stem, and the integrity of these transport tissues must be maintained and protected for years if not decades. Parenchyma cells form an interconnected three-dimensional lattice throughout secondary xylem and phloem and perform critical roles in all of these tasks, yet our understanding of their physiology, the nature of their symplasmic connections, and their activity at the symplast-apoplast interface is very limited. This review highlights key historical work as well as current research on the structure and function of parenchyma in secondary vascular tissue in the hopes of spurring renewed interest in this area, which has important implications for whole-plant transport processes and resource partitioning. © 2013 The Author.

With enhancing mixing in micro- or nanofluidic applications in mind, the problem of maximizing fluid transport across a fluid interface subject to an available energy budget is examined. The optimum cross-interface perturbing velocity is obtained explicitly in the time-periodic instance using an Euler-Lagrange constrained optimization approach. Numerical investigations which calculate transferred lobe areas and cross-interface flux are used to verify that the predicted strategy achieves optimum transport. Explicit active protocols for achieving this optimal transport are suggested. © 2012 American Physical Society. Source

Species distribution models (SDMs) are increasingly used to predict distributions of invasive species. If successful, these models can help managers target limited resources for monitoring and controlling invasive species to areas of high invasion risk. Model accuracy is usually determined using current species distributions, but because invasive species are not at equilibrium with the environment, high current accuracy may not indicate high future accuracy. I used 1982 species distribution data from Bolleswood Natural Area, Connecticut, USA, to create SDMs for two forest invaders, Celastrus orbiculatus and Rosa multiflora. I then used more recent data, from 1992 and 2002, as validation data sets to determine how model accuracy changed over time and if current and future accuracy were related. I also tested if three alternative approaches - iterative modeling, alternative methods of choosing suitability thresholds and using a risk assessment framework - improved accuracy in predicting future distributions. Model accuracy declined over time with greater declines for models of the species (Celastrus) with the higher initial accuracy. By 2002, 49% of Celastrus and 85% of Rosa new occurrences were correctly predicted by models. Neither iterative modeling nor alternative thresholds improved accuracy of predicting 2002 occurrences, but a risk assessment framework showed promise for guiding monitoring efforts. These results suggest that measures of current accuracy may not indicate a model's predictive accuracy and must be used cautiously. Distinguishing between predictions of current and future distributions is critical. While iterative models were not successful in this study, I argue that using models in a risk assessment framework closely tied to monitoring will greatly increase the utility of SDMs for managing invasive species. © 2012 Elsevier B.V.

In 1971, Edward Keller proposed the velocity-reversal hypothesis to describe observations where near-bed velocities in pools increased at a faster rate than in riffles. The reversal in conditions was used to explain the maintenance of pool-riffle sequences. The hypothesis continues to draw interest, and research shows that velocity reversals occur in limited conditions, but average cross-sectional velocities in pools do not universally exceed those in riffles at near-bankfull flows. A consensus is now beginning to form that flow convergence in pools is common at high flow and helps to form an isolated region of jet flow with high velocities that maintains the characteristics of the pool-riffle sequence. © The Author(s) 2010.
