We update an analytic impact gardening model (Costello et al., 2018, https://doi.org/10.1016/j.icarus.2018.05.023) to calculate the depth gardened by impactors on the Moon and Mercury and assess the implications of our ...

An in vivo test of the biologically relevant roles of carotenoids as antioxidants in animals

This file contains a digital map of the Indira Gandhi Canal (India) in Google Earth KMZ format that was produced as part of The IBT Water Project at Auburn University. The Indira Gandhi Canal was primarily designed to ...

Indirect Impacts of Recreational Scuba Diving: Patterns of Growth and Predation in Branching Stony Corals 

Guzner, Barak; Novplansky, Ariel; Shalit, Or; Chadwick, Nanette E. (2021-01-27)
The highest recorded rates of recreational SCUBA diving occur on coral reefs at Eilat in the northern Red Sea, where many scleractinian corals are damaged by physical contact with divers. We compared coral skeletal growth ...

The influence of maternal nesting behaviour on offspring survival: evidence from correlational and cross-fostering studies 

Addis, Elizabeth; Warner, Daniel; Pruett, Jenna (2019-04-22)
The maternal effect of nesting behaviour is important in oviparous species because choice of microhabitat (e.g. shade cover, temperature) can determine the environment in which embryos develop. In turn, this maternal choice ...

Integral approximations in ab initio, electron propagator calculations 

Flores-Moreno, Roberto; Ortiz, J.V. (2021-01-26)
Treatments of interelectronic repulsion that avoid four-center integrals have been incorporated in ab initio, electron-propagator calculations with diagonal self-energy matrices. Whereas the formal scaling of arithmetic ...

The interaction-induced dipole of H-2-H: New ab initio results and spherical tensor analysis 

Lee, Hua-Kuang; Li, Xiaoping; Miliordos, Evangelos; Hunt, Katharine L.C.; https://orcid.org/0000-0003-3471-7133 (2020-04-08)
We present numerical results for the dipole induced by interactions between a hydrogen molecule and a hydrogen atom, obtained from finite-field calculations in an aug-cc-pV5Z basis at the unrestricted coupled-cluster level ...

Intermediate shocks in three-dimensional magnetohydrodynamic bow-shock flows with multiple interacting shock fronts 

Cable, S.; Lin, Y.; Holloway, J. L.; 0000-0001-8003-9252 (2020-06-18)
Previous MHD simulations predict that when switch-on shock conditions obtain in the solar wind, the bow shock produced in front of an ellipsoidal obstacle will produce a unique bow shock configuration that includes a concave ...

Interpretation of the photoelectron spectra of superalkali species: Li3O and Li3O- 

Zein, S.; Ortiz, J. V. (2020-10-02)

Zein, S; Ortiz, J. V.; Ortiz, Joseph Vincent (2020-08-20)
Recently measured photoelectron spectra of the Na3O- anion have been interpreted with the aid of ab initio electron propagator calculations. As in the case of the Li3O-, we propose that the photoionization of ground and ...
