Changes in leaf physiology with tree age and size could alter forest growth, water yield, and carbon fluxes. We measured tree water flux (Q) for 14 ponderosa pine trees in two size classes (12 m tallâ€¦ (More)

The present study examines the manner in which several whole-tree water transport properties scale with speciesspecific variation in sapwood water storage capacity. The hypothesis that constraints onâ€¦ (More)

We determined the axial and radial xylem tension gradients in trunks of young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) trees. Axial specific conductivity (k(s-a)) and sap flux density (Js)â€¦ (More)

Heat and stable isotope tracers were used to study axial and radial water transport in relation to sapwood anatomical characteristics and internal water storage in four canopy tree species of aâ€¦ (More)

This document contains a list of open problems and research directions that have been suggested by participants at the Bertinoro Workshop on Sublinear Algorithms (May 2011) and IITK Workshop onâ€¦ (More)

We continue the study of approximating the number of distinct elements in the data stream model to within a (1 Â± ) factor with constant probability. It was shown by Indyk and Woodruff (FOCS, 2003)â€¦ (More)

And recall that the INDEX model has the lower bound for deterministic communication complexity: CCÎ´(INDEX) â‰¥ I(M ;X|R) â‰¥ n(1âˆ’H(Î´)), where R is the shared common random string. We need a lower boundâ€¦ (More)

We characterized Husserl's approach to intentionality as " phenomenological " because it attempts to explain intentionality exclusively in terms of the contents of intentional experiÂ ences asâ€¦ (More)

We give a 1-pass Ã•(m1âˆ’2/k)-space algorithm for computing the k-th frequency moment of a data stream for any real k > 2. Together with the lower bounds of [1, 2, 3], this resolves the main problemâ€¦ (More)

As we have seen, one way to resolve this question in the positive is to use the following two-step process: First show that the number of random bits for any BPP algorithm can be reduced from nc toâ€¦ (More)
