Multi-level Monte Carlo (MLMC) algorithms have been extensively applied in recent years to obtain schemes that often converge at faster rates than corresponding traditional Monte Carlo methods. In this talk, we shall discuss a randomized method introduced in joint work with Chang-han Rhee, and then describe a stratified alternative estimator. Our principal focus in the talk will be on applicati...

Building on a notion of keys for XML, we propose a novel indexing scheme for hierarchical data that is based not only on the structure but also the content of the data. The index can be used to check the validity of data with respect to a set of key specifications, as well as for efficiently evaluating queries and updates on key paths. We develop algorithms for the construction and incremental ...

Octupole deformations and related collective excitations are analyzed using the framework of nuclear density functional theory. Axially-symmetric quadrupole-octupole constrained self-consistent mean-field (SCMF) calculations with a choice universal energy pairing interaction performed for Xe, Ba, Ce isotopes from proton-rich to neutron-rich regions, Se, Kr, Sr isotopes, in which enhanced octupo...

Octupole correlations in the low-energy collective states of neutron-rich nuclei with neutron number $N\ensuremath{\approx}56$ are studied within interacting boson model (IBM) that is based on nuclear density-functional theory. The constrained self-consistent mean-field (SCMF) calculations using a universal energy density functional and pairing interaction provide potential-energy surfaces term...

the purpose of this experimental study was to evaluate the effect of chicken amniotic fluid (af) on a cross section of rat sciatic nerves. thirty adult male sprague-dawley rats weighing 275 to 300 g, were randomized into three groups treated with (1) amniotic fluid or af (n=10), (2) normal saline or ns (n=10), and (3) sham surgery (n=10). the af was aspirated from the amniotic cavity of incubat...

An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...

Objective(s) Some properties of neuraminidase produced by Pseudomonas aeruginosa PAO1 growth in a defined medium (BHI) were examined and evaluated for its features. Materials and Methods The obtained supernatant enzyme of P. aeruginosa PAO1 cultures was used in a sensitive fluorometric assay by using 2'-(4-methylumbelliferyl) a-D-N acetylneuraminic acid as substrate. As hydrolyzing MUN with ...

Nutrient deposition to tropical forests is increasing, which could affect soil fluxes of nitrous oxide (N2O), a powerful greenhouse gas. We assessed the effects of 35–56 months of moderate nitrogen (N) and phosphorus (P) additions on soil N2O fluxes and net soil N-cycling rates, and quantified the relative contributions of nitrification and denitrification to N2O fluxes. In 2008, a nutrient man...
