A stable and optimally convergent generalized FEM (SGFEM) for linear elastic fracture mechanics
Abstract In this paper, we investigate the accuracy and conditioning of the Stable Generalized FEM (SGFEM) and compare it with standard Generalized FEM (GFEM) for a 2-D fracture mechanics problem.Expand

Stable isotopes reveal widespread anaerobic methane oxidation across latitude and peatland type.
Peatlands are an important source of the atmospheric greenhouse gas methane (CH4). Although CH4 cycling and fluxes have been quantified for many northern peatlands, imprecision in process-basedExpand

Controls on bacterial and archaeal community structure and greenhouse gas production in natural, mined, and restored Canadian peatlands
Northern peatlands are important global C reservoirs, largely because of their slow rates of microbial C mineralization. Particularly in sites that are heavily influenced by anthropogenicExpand

Neuronal model with distributed delay: analysis and simulation study for gamma distribution memory kernel
A single neuronal model incorporating distributed delay (memory)is proposed. The stochastic model has been formulated as a Stochastic Integro-Differential Equation (SIDE) which results in theExpand

Improved conditioning and accuracy of GFEM/XFEM for three-dimensional fracture mechanics
Abstract In this paper, we present an extension of the Stable Generalized FEM (SGFEM) for 3-D fracture mechanics problems. Numerical experiments show that the use of available singular enrichmentExpand

Active Methanotrophs in Two Contrasting North American Peatland Ecosystems Revealed Using DNA-SIP
The active methanotroph community was investigated in two contrasting North American peatlands, a nutrient-rich sedge fen and nutrient-poor Sphagnum bog using in vitro incubations and 13C-DNAExpand

Anaerobic Oxidation of Methane in Northern Peatlands
Anaerobic oxidation of methane (AOM) in peatlands was investigated using 13 carbon isotope tracers. Existence of AOM in marine and freshwater ecosystems is well known, but only recently has solidExpand

Visible spectrum of titanium dioxide.
The electronic spectrum in the region 17 500 cm(-1) to 18 850 cm(-1) of a cold molecular beam of TiO(2) has been investigated using laser induced fluorescence (LIF) and mass-resolved resonanceExpand

The visible spectrum of zirconium dioxide, ZrO2.
The electronic spectrum of a cold molecular beam of zirconium dioxide, ZrO(2), has been investigated using laser induced fluorescence (LIF) in the region from 17,000 cm(-1) to 18,800 cm(-1) and byExpand
