Heat-induced maternal effects shapes avian eggshell traits and embryo response to high temperatures 

Hoffman, Alexander; Dees, Leslie; Wada, Haruka; orcid.org/0000-0003-1224-9965 (2021-03-29)
Populations without a sufficient rate of genetic adaptation may risk extinction in the face of rapid environmental change, however, phenotypic plasticity can facilitate their persistence. For example, mothers can prepare ...

Increased cellular free cholesterol in macrophage-specific Abca1 knock-out mice enhances pro-inflammatory response of macrophages 

Zhu, Xuewei; Lee, Ji-Young; Timmins, Jenelle M.; Brown, J. Mark; Boudyguina, Elena; Mulya, Anny; Gebre, Abraham K.; Willingham, Mark C.; Hiltbold, Elizabeth M.; Mishra, Nilamadhab (2021-03-23)
Macrophage-specific Abca1 knock-out (Abca1(-M/-M)) mice were generated to determine the role of macrophage ABCA1 expression in plasma lipoprotein concentrations and the innate immune response of macrophages. Plasma lipid ...

Data from: Dumpsters and other human structures as habitat for invasive African rock agama lizards in Florida 

Mitchell, Timothy S; Folt, Brian; Hall, Joshua M (2021-03-22)
Invasive species often use habitat differently than native species and can benefit by using underutilized habitats during the invasion process. The Peter’s Rock Agama (Agama picticauda) — native to savannahs of sub-Saharan ...

Politics a "Chilly" Environment for Undergraduate Women in Norway 

Ballen, Cissy J.; Lee, Dahsol; Rakner, Lise; Sehoya, Cotner (2021-03-22)
Gender differences in academic performance and attitudes are widespread in male-stereotyped disciplines but rarely are studied in the social sciences. To assess the extent that gender influences the behavior of undergraduate ...

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 ...

Anatomy of the Laminar Organs of Commelina erecta (Commelinaceae) 

Dute, Roland R.; Jackson, Brian E.; Adkins, Ryan D.; Folkerts, Debbie R. (2021-01-27)
A study was undertaken to compare the anatomy of the laminar floral parts with that of the spathes and leaves of Commelina erecta L. Each flower has two types of petals and two types of sepals. In contrast to the other ...

Electron binding energies and Dyson orbitals of Al(5)O(m)(-) (m=3,4,5) and Al(5)O(5)H(2)(-) 

Guevara-Garcia, Alfredo; Martinez, Ana; Ortiz, J.V. (2021-01-26)
Photoelectron spectra of Al5Om − m=3–5 and of the anion produced by the dissociative adsorption of a water molecule by Al5O4 − are interpreted with density-functional geometry optimizations and electron-propagator ...

Assessment of transition operator reference states in electron propagator calculations 

Flores-Moreno, Roberto; Zakrzewski, V. G.; Ortiz, J.V. (2021-01-26)
The transition operator method combined with second-order, self-energy corrections to the electron propagator TOEP2 may be used to calculate valence and core-electron binding energies. This method is tested on a set of ...

OH3- and O2H5- double Rydberg anions: Predictions and comparisons with NH4- and N2H7- 

Melin, Junia; Ortiz, J.V. (2021-01-26)
A low barrier in the reaction pathway between the double Rydberg isomer of OH3 − and a hydride-water complex indicates that the former species is more difficult to isolate and characterize through anion photoelectron ...

Surface Green’s function calculations: A nonrecursive scheme with an infinite number of principal layers 

Kletsov, Aleksey; Dahnovsky, Yuri; Ortiz, J.V. (2021-01-26)
A novel computational method for a surface Green’s function matrix is introduced for the calculation of electrical current in molecular wires. The proposed nonrecursive approach includes an infinite number of principal ...

Sequential addition of H2O, CH3OH, and NH3 to Al3O3-: A theoretical study 

Guevara-Garcia, Alfredo; Martinez, Ana; Ortiz, J.V. (2021-01-26)
Photoelectron spectra of two species, Al3O3(H2O)(2)(-) and Al3O3(CH3OH)(2)(-), that are produced by the addition of two water or methanol molecules to Al3O3- are interpreted with density-functional geometry optimizations ...

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 ...
