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...

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...

Service life of treated and untreated fence posts on the T. J. Starker post farm : supplement to progress report 11

Creator:: Forest Products Research Center, Graham, Robert D., and Miller, Donald J.
Abstract:: This summary of the 1958 inspection of the T. J. Starker Post Farm is issued as a supplement to the detailed Progress Report 11, October 1957. Complete Progress reports to be issued at intervals of 2-5 years will describe post series mentioned here and will summarize previous work.
