contraceptives. Demographic surveys of contraceptive use in the United States typically have collected and reported data only on use of single methods; when more than one method is described by a respondent, the one reported by the investigator is usually the method that most effectively prevents pregnancy.4 Likewise, studies of HIV and STD risk often do not include data on contraceptive use fo...

As a population subgroup, older people are more vulnerable to malnutrition especially those who are institutionalised. Recognition of deteriorating or poor nutritional status is key in reversing the effects of undernutrition and reinforces the value of regular weight checks and/or the use of screening tools. Commercially produced supplements are often the first option used to address undernutri...

Three dimensional (3D) displays are becoming popular consumer technologies. The 3D effect mainly comes from the projection of two respective images on right and left eyes. For example, some movie projectors superpose two different images on the same screen with orthogonal polarlization states so that viewers wearing polarlization glasses see different images with different eyes. Head-mounted di...

Single-source shortest paths. In the single-source shortest paths problem (SSSP), we are given a graph G = (V,E) and a source node s ∈ V , and we must compute d(s, v) for all v ∈ V . If the graph is unweighted, we can solve this in O(m + n) time by breadth-first search (BFS). If the graph has nonnegative integer weights, we can use Dijkstra’s algorithm with Fibonacci heaps, yielding a runtime o...

Basal cells are multipotent airway progenitors that generate distinct epithelial cell phenotypes crucial for homeostasis and repair of the conducting airways. Little is known about how these progenitor cells expand and transition to differentiation to form the pseudostratified airway epithelium in the developing and adult lung. Here, we show by genetic and pharmacological approaches that endoge...

I am a third year Ph.D. student in Applied Science & Technology. My research advisor is Graham Fleming, in the Department of Chemistry. Our group studies energy transfer and photoprotection in photosynthesis of fundamental concern for alternative energy and food production applications. I hold a B.S. in Physics and Political Science from the University of Minnesota Twin Cities, and hope to find...

D evelopment agencies want their interventions to be sustainable. The Offi ce of Sustainable Development of the Bureau for Africa of the United States Agency for International Development defi nes sustainability as " the ability of host country entities (community, public and/or private) to assume responsibility for programs and/or outcomes without adversely affecting the ability to maintain or...

To increase understanding of agricultural intensification processes over time and their sustainability, we studied dimensions sustainability in the context ongoing expansion intensive, commercial mono-cropping banana Southwestern Uganda. In our approach considered five sustainability: economic, productivity, environment, social human. We compared farming systems 1998 2018 integrated a gender le...
