Direct ΔMBPT(2) method for ionization potentials, electron affinities, and excitation energies using fractional occupation numbers 

Beste, Ariana; Vazquez-Mayagoitia, Alvaro; Ortiz, J. V.; Ortiz, Joseph V. (2020-01-16)
A direct method (D-ΔMBPT(2)) to calculate second-order ionization potentials (IPs), electron affinities (EAs), and excitation energies is developed. The ΔMBPT(2) method is defined as the correlated extension of the ΔHF ...

Basis set converged weak interaction energies from conventional and explicitly correlated coupled-cluster approach 

Patkowski, Konrad (2020-01-16)
Interaction energies for seven weakly bound dimers involving helium, argon, water, and methane are computed using large correlation-consistent basis sets augmented with bond functions. The estimates of the coupled-cluster ...

A generalized any-particle propagator theory: Prediction of proton affinities and acidity properties with the proton propagator 

Diaz-Tinoco, Manuel; Romero, Jonathan; Ortiz, J. V.; Reyes, Andres; Flores-Moreno, Roberto; Ortiz, Joseph V. (2020-01-16)
We have recently extended the electron propagator theory to the treatment of any type of particle using an Any-Particle Molecular Orbital (APMO) wavefunction as reference state. This approach, called APMO/PT, has been ...

Bakr, Brandon W.; Smith, Daniel G. A.; Patkowski, Konrad; Brandon W. Bakr, Daniel G. A. Smith, and Konrad Patkowski (2020-01-16)
A new highly accurate interaction potential is constructed for the He–H2 van der Waals complex. This potential is fitted to 1900 ab initio energies computed at the very large-basis coupled-cluster level and augmented by ...

Two-photon imaging of Zn2+ dynamics in mossy fiber boutons of adult hippocampal slices 

Khan, Mustafa; Goldsmith, Christian R.; Huang, Zhen; Georgiou, John; Luyben, Thomas T.; Roder, John C.; Lippard, Stephen J.; Okamoto, Kenichi (2020-01-16)
Mossy fiber termini in the hippocampus accumulate Zn2+, which is released with glutamate from synaptic vesicles upon neural excitation. Understanding the spatiotemporal regulation of mobile Zn2+ at the synaptic level is ...

Excitation energies, photoionization cross sections, and asymmetry parameters of the methyl and silyl radicals 

Velasco, A. M.; Lavin, C.; Dolgounitcheva, O.; Ortiz, J. V. (2020-01-16)
Vertical excitation energies of the methyl and silyl radicals were inferred from ab initio electron propagator calculations on the electron affinities of CH3 + and SiH3 +. Photoionization cross sections and angular ...

High-Throughput Sequencing Characterizes Intertidal Meiofaunal Communities in Northern Gulf of Mexico (Dauphin Island and Mobile Bay, Alabama) 

Brannock, Pamela M.; Waits, Damien S.; Sharma, Jyotsna; Halanych, Kenneth M. (2019-12-20)
Abstract. Meiofauna are important components of food webs and for nutrient exchange between the benthos and water column. Recent studies have focused on these communities in the Gulf of Mexico due to potential impacts of ...

Data for: Adaptive seasonal shift towards investment in fewer, larger offspring: Evidence from field and laboratory studies 

Hall, Joshua M; Mitchell, Timothy S; Thawley, Christopher J; Stroud, James T; Warner, Daniel A; 0000-0002-5587-3402 (2019-12-20)
1. Seasonal changes in reproduction have been described for many taxa. As reproductive seasons progress, females often shift from greater energetic investment in many small offspring towards investing less total energy ...

Thermal Spikes Caused by the Urban Heat Island Effect Result in Differential Egg Survival of a Non-native Lizard (Anolis cristatellus) 

Hall, Joshua M; Warner, Daniel A; http://orcid.org/0000-0002-5587-3402 (2019-09-15)
Embryonic development in ectotherms is very sensitive to abiotic nest conditions. In reptiles, high incubation temperatures often result in relatively short incubation periods and large hatching size, but extremely high ...
