A Polynomial-Time Approximation Scheme for Euclidean Steiner Forest

Creator:: Borradaile, Glencora, Klein, Philip N., and Mathieu, Claire
Abstract:: We give a randomized O(n polylog n)-time approximation scheme for the Steiner forest problem in the Euclidean plane. For every fixed ε > 0 and given n terminals in the plane with connection requests between some pairs of terminals, our scheme finds a (1 + ε) approximation to the minimum-length...

Early Selection for Improving Volume Growth in Coastal Douglas-fir Breeding Programs

Creator:: Ye, T. Z. and Jayawickrama, K. J. S.
Abstract:: Measurements on growth traits up to 41 years of age from 68 progeny sites in eight first-generation breeding zones of coastal Douglas-fir (Pseudotsuga menziesii [MIRB.] FRANCO var. menziesii) in the US Pacific Northwest were used to investigate age trends of genetic parameters and to determine optimum age of selection. Heritabilities...

Hitting Capacity: Implications for the Valuation of Outdoor Recreation

Creator:: Hilger, James and Steiner, Christopher
Abstract:: Choices are often limited as the most popular alternatives reach capacity and sell out; thereafter, selection is over less preferred choices. In the context of nonmarket goods, willingness to pay (WTP) welfare measures provide an estimate of the value of characteristics – often calculated through the modeling of preferences using...

Robustness of Sharing Rules Under Climatic Changes - The Case of International Fisheries Agreement

Creator:: Brandt, Urs Steiner and Kronbak, Lone Grønbæk
Abstract:: Many international fisheries agreements involve sharing rules. These rules are normally stable rules, not contingent on shifts in the relative distribution or development of the resource. In the latest IPCC report, the most likely future scenario is an increase in the global mean temperature, and most severely in high latitudes....

Ultrafast Nonlinear Optical Effects in Semiconductor Quantum Wells Resonantly Driven by Strong Few-Cycle Terahertz Pulses

Creator:: Tomaino, J. L., Jameson, A. D., Lee, Yun-Shik, Prineas, J. P., Steiner, J. T., Kira, M., and Koch, S. W.
Abstract:: Intraexciton transitions in semiconductor quantum wells are modulated by strong and tunable few-cycle terahertz pulses. Time-resolved terahertz-pump and optical-probe measurements demonstrate that the 1s heavy-hole and light-hole exciton resonances undergo large-amplitude spectral modulations when the terahertz radiation is tuned near the 1s–2p intraexciton transition. The strong nonlinear optical transients exhibit...

Carbonates dissolution and precipitation in hemipelagic sediments overlaid by supersaturated bottom-waters - Gulf of Aqaba, Red Sea

Creator:: Steiner, Zvi, Lazar, Boaz, Reimers, Clare E., and Erez, Jonathan
Abstract:: Whether CaCO₃ dissolves within the top centimeters of marine sediments overlaid by deep, supersaturated bottom waters remains an area of debate in geochemistry. This uncertainty stems from the fact that different methods used to assess CaCO₃ dissolution rates often provide what appear to be profoundly different results. Here we combine...

The Dynamic Role of Sablefish in a Mutlispecies, Multigear IFQ Fishery

Creator:: Holland, Dan and Steiner, Erin
Abstract:: Individual fishing quota (IFQ) systems are typically expected to increase the profitability of a fishery and improve sustainability by ensuring catches remain within quotas. They can also have important distributional and ecological implications that result from shifts in catch and effort between different gears, regions, and habitats. In multispecies fisheries...
