Facets of an Assignment Problem with 0–1 Side Constraint
(Kluwer Academic Publishers; Springer Science+Business Media, 2000-09)
We show that the problem of finding a perfect matching satisfying a single equality constraint with a 0–1 coefficients in an n × n incomplete bipartite graph, polynomially reduces to a special case of the same peoblem ...
Seed morphology and anatomy and its utility in recognizing subfamilies and tribes of Zingiberaceae
(Botanical Society of AmericaWiley Periodicals, Inc., 2015-11)
Stable isotope food-web analysis and mercury biomagnification in polar bears ( Ursus maritimus )
(Blackwell Publishing Ltd, 2009-12)
Mercury (Hg) biomagnification occurs in many ecosystems, resulting in a greater potential for toxicological effects in higher-level trophic feeders. However, Hg transport pathways through different food-web channels are ...
Microbial Cycling of C and N in Northern Hardwood Forests Receiving Chronic Atmospheric NO 3 − Deposition
(Springer-Verlag; Springer Science+Business Media, Inc., 2006-03)
Sugar maple ( Acer saccharum Marsh.)-dominated northern hardwood forests in the upper Lakes States region appear to be particularly sensitive to chronic atmospheric NO 3 − deposition. Experimental NO 3 − deposition (3 g ...
Implementation and analysis of polymeric microstructure replication by micro injection molding
(IOP Publishing Ltd, 2004-03-01)
This paper presents the adaptation of a conventional injection molding process to the mass replication of polymeric microstructures with appropriate mold design and process control. Using wet-etched silicon wafers with ...
Hatch Dates, Growth, Survival, and Overwinter Mortality of Age‐0 Alewives in Lake Michigan: Implications for Habitat‐Specific Recruitment Success
(Taylor & Francis GroupWiley Periodicals, Inc., 2007-09)
Alewives Alosa pseudoharengus are key components of Laurentian Great Lakes ecosystems and spawn in multiple habitat types. Exploration of alewife early life history dynamics within these different habitats should help ...
Simultaneous conjugate observations of small‐scale structures in Saturn's dayside ultraviolet auroras: Implications for physical origins
(Wiley Periodicals, Inc.Space Telescope Sci. Inst, 2013-05)
Small‐scale features in Saturn's dayside UV auroras are examined using images obtained on 32 Hubble Space Telescope visits close to Saturn equinox when both northern and southern emissions were simultaneously observed, ...
A Geometric Framework for Evaluating Rare Variant Tests of Association
(Wiley Periodicals, Inc., 2013-05)
The wave of next‐generation sequencing data has arrived. However, many questions still remain about how to best analyze sequence data, particularly the contribution of rare genetic variants to human disease. Numerous ...
Inhibition of Vesicular Glutamate Uptake by Rose Bengal-Related Compounds: Structure–Activity Relationship
(Kluwer Academic Publishers-Plenum Publishers; Springer Science+Business Media, Inc., 2005-03)
Synaptic vesicular accumulation of glutamate is a vital initial step in glutamate transmission. We have previously shown that Rose Bengal, a polyhalogenated fluorescein analog, is a potent inhibitor of glutamate uptake ...
