Toward a Spin- and Parity-Independent Nucleon-Nucleon Potential [PDF]

open access: yes, 2001
A supersymmetric inversion method is applied to the singlet $^1S_0$ and $^1P_1$ neutron-proton elastic phase shifts. The resulting central potential has a one-pion-exchange (OPE) long-range behavior and a parity-independent short-range part; it fits ...

Estimating the Interferometric Vertical Wavenumber From Range Shifts [PDF]

open access: yesIEEE Geoscience and Remote Sensing Letters, 2023
The estimation of the interferometric vertical wavenumber over sloped terrain is an integral step for many interferometric and tomographic synthetic aperture radar (SAR) applications. The state of the art for this estimation is to calculate the angle of incidence and the local terrain slope after geometric corregistration has been performed.

Ditransitive verbs and the ditransitive construction: a diachronic perspective [PDF]

open access: yes, 2011
This paper argues for the adoption of a construction-based perspective to the investigation of diachronic shifts in valency, which is a hitherto largely neglected topic in the framework of valency grammar. On the basis of a comparison of the set of verbs

Evaluating distributional shifts in home range estimates [PDF]

open access: yesEcology and Evolution, 2015
AbstractA variety of methods are commonly used to quantify animal home ranges using location data acquired with telemetry. High‐volume location data from global positioning system (GPS) technology provide researchers the opportunity to identify various intensities of use within home ranges, typically quantified through utilization distributions (UDs ...

Climate Change Will Re-draw the Map for Marine Megafauna and the People Who Depend on Them

open access: yesFrontiers in Marine Science, 2020
Climate change is expected to dramatically alter the distribution of many marine megafauna, impacting the people and economies that depend upon them. We build on the recent literature by developing a framework to describe the effects these changes will ...

Estimating the Potential of Insects from Warmer Regions to Overwinter in Colder Regions under a Warming Winter Scenario Using Simulation Experiments: A Case Study in Sesamia nonagrioides

open access: yesInsects, 2023
Ongoing climate change and anthropogenic pressure are having a profound influence on insects, causing species diversity to decline and populations to shrink. Insect pests invade new areas and cause economic and human health problems.

Ground state properties of exotic nuclei near Z=40 in the relativistic mean-field theory, [PDF]

open access: yes, 1995
Study of the ground-state properties of Kr, Sr and Zr isotopes has been performed in the framework of the relativistic mean field (RMF) theory using the recently proposed relativistic parameter set NL-SH.

A test for a shift in the boundary of the geographical range of a species [PDF]

open access: yesBiology Letters, 2014
One predicted impact of climate change is a poleward shift in the boundaries of species ranges. Existing methods for identifying such a boundary shift based on changes in the observed pattern of occupancy within a grid of cells are sensitive to changes in the overall rate of sightings and their latitudinal distribution that are unconnected

Changes in Community Composition and Functional Traits of Bumblebees in an Alpine Ecosystem Relate to Climate Warming

open access: yesBiology, 2023
Climate warming has been observed as the main cause of changes in diversity, community composition, and spatial distribution of different plant and invertebrate species.

Convective line shifts for the Gaia RVS from the CIFIST 3D model atmosphere grid [PDF]

open access: yes, 2013
To derive space velocities of stars along the line of sight from wavelength shifts in stellar spectra requires accounting for a number of second-order effects.
