A review of the historic and present ecological role of aquatic and shoreline wood, from forest to deep sea

Biological Reviews, EarlyView.
ABSTRACT The ecology of forests, their losses, and terrestrial wood decomposition dynamics have been intensively studied and reviewed. In the aquatic realm, reviews have concentrated on large wood (LW) in rivers and the transition from freshwater to marine environments in the Pacific Northwest of North America. However, a comprehensive global synthesis

The Star Formation Rate Function of the Local Universe

, 2004
We have derived the bivariate luminosity function for the far ultraviolet (1530Angstroms) and far infrared (60 microns). We used matched GALEX and IRAS data, and redshifts from NED and PSC-z. We have derived a total star formation luminosity function phi(

On one-multiplier implementations of FIR lattice structures [PDF]

, 1987
One-multiplier realizations for certain recently reported FIR lossless lattice structures are investigated. The multiplier extraction approach is used to show that there does not exist a real one-multiplier realization whereas it is possible to get ...

Spatial metrics in fire ecology: seeking consistency amidst complexity

Biological Reviews, EarlyView.
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Novel FIR Inversion with Only FIRS

, 2005
The inversion of an FIR data sampling is usually stated to be possible with the use of a potentially unstable IIR, and in particular circumstances. It is possible to accomplish the same inversion with the doubling of an FIR sampling and with only FIRs for the sampling and the inversion. This note presents the configuration, which appently is not in the

Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

The Canadian Journal of Chemical Engineering, EarlyView.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

UV and FIR selected samples of galaxies in the local Universe. Dust extinction and star formation rates

, 2004
We have built two samples of galaxies selected at 0.2micron (hereafter UV) and 60micron (hereafter FIR) covering a sky area of 35.36 deg^2. The UV selected sample contains 25 galaxies brighter than AB_0.2=17mag.

Seizure forecasting with epilepsy cycles: On the causality of forecasting pipelines

Epilepsia, EarlyView.
Abstract Objective Seizure risk is modulated by multiscale brain rhythms. Previous studies using cycles in electroencephalography, heart rate, and wearable data suggest the possibility of forecasting seizures days in advance. However, they commonly rely on methods requiring (days of) information from time points beyond the moment of forecast (noncausal
