Correlation Energy Estimators based on M{\o}ller-Plesset Perturbation Theory

open access: yes, 1996
Some methods for the convergence acceleration of the M{\o}ller-Plesset perturbation series for the correlation energy are discussed. The order-by-order summation is less effective than the Feenberg series.

Diversity and Spatiotemporal Distribution of Fish in a Highland Lake in China Based on Environmental DNA Metabarcoding

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We analyzed water samples from different seasons and locations in Erhai Lake to determine whether eDNA barcoding can effectively show the diversity of fish in such lakes. In the manuscript, we discuss our findings regarding the range of species found, their spatiotemporal distribution, and whether eDNA barcoding gave similar results to traditional ...

Non-positivity of the Wigner function and bounds on associated integrals

open access: yes, 2003
The Wigner function shares several properties with classical distribution functions on phase space, but is not positive-definite. The integral of the Wigner function over a given region of phase space can therefore lie outside the interval [0,1].

How Hydropower Operations Mitigate Flow Forecast Uncertainties to Maintain Grid Services in the Western U.S.

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Hydropower facilities represent a key electricity generating resource in the U.S. Western Interconnection. These facilities rely upon forecasts of inflow when scheduling releases to generate electricity. However, hydropower operations represented in bulk power systems models do not reflect uncertainty in inflow forecasts.

Environmental improvement and conservation of useful pastures for wild herbivores in a Regional Park on the Apennines mountains

open access: yesItalian Journal of Animal Science, 2010
In order to investigate some effects of the environmental management with faunistic purpose on pastures located on the Apennines mountains, in open areas subjected to bracken fern (Pteridium aqulinum) infestation, samples of vegetation were taken for ...
