Interpretation of the photoelectron spectra of superalkali species: Li3O and Li3O-
(2020-10-02)
The present paper deals with the interpretation of the photoelectron spectrum of the Li3O-. After several failed attempts to attribute all of the observed peaks in the experimental spectrum to anionic species, neutral ...
Interpretation of the photoelectron spectra of superalkali species: Na3O and Na3O-
(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 ...
On the accuracy of explicitly correlated coupled-cluster interaction energies - have orbital results been beaten yet?
(2020-08-20)
The basis set convergence of weak interaction energies for dimers of noble gases helium through
krypton is studied for six variants of the explicitly correlated, frozen geminal coupled-cluster singles, doubles, and ...
Valence and diffuse-bound anions of noble-gas complexes with uracil
(2020-08-20)
Valence-bound (VB) and diffuse-bound (DB) anions of noble-gas (Ar, Kr, and Xe) complexes with
uracil have been studied with ab initio methods. MP2 optimizations revealed minima corresponding
to anions of both kinds in ...
Subunit D of RNA Polymerase from Methanosarcina acetivorans Contains Two Oxygen-labile [4Fe-4S] Clusters IMPLICATIONS FOR OXIDANT-DEPENDENT REGULATION OF TRANSCRIPTION
(2020-08-20)
Subunit D of multisubunit RNA polymerase from many species of archaea is predicted to bind one to two iron-sulfur (Fe-S) clusters, the function of which is unknown. A survey of encoded subunit D in the genomes of sequenced ...
Data for: Ecologically relevant thermal fluctuations enhance offspring fitness: biological and methodological implications for studies of thermal developmental plasticity
(2020-08-03)
Natural thermal environments are notably complex and challenging to mimic in controlled studies. Consequently, our understanding of the ecological relevance and underlying mechanisms of organismal responses to thermal ...
Eukaryotic N-Glycosylation Occurs via the Membrane-anchored C-terminal Domain of the Stt3p Subunit of Oligosaccharyltransferase
(2020-07-24)
N-Glycosylation is an essential and highly conserved protein
modification. In eukaryotes, it is catalyzed by a multisubunit
membrane-associated enzyme, oligosaccharyltransferase (OT).
We report the high resolution ...
A Remodeled Protein Arginine Methyltransferase 1 (PRMT1) Generates Symmetric Dimethylarginine
(2020-07-24)
Protein arginine methylation is emerging as a significant post-translational modification involved in various cell processes and human diseases. As the major arginine methylation enzyme, protein arginine methyltransferase ...
Generation of anomalous flows near the bow shock by its interaction with interplanetary discontinuities
(2020-06-30)
Two-dimensional hybrid simulations using a curvilinear coordinate system are carried out to study the interaction of the Earth's bow shock (BS) with an interplanetary directional discontinuity. In particular, plasma flow ...
Three-dimensional MHD simulations of interplanetary rotational discontinuities impacting the Earth's bow shock and magnetosheath
(2020-06-30)
The first ever fully three-dimensional magnetohydrodynamic (MHD) simulations of the detailed effects of MHD discontinuities on the magnetosheath have been performed. The simulation results predict that the interaction ...
Solitary potential structures associated with ion and electron beams near 1 R-E altitude

A hybrid simulation is carried out to study the evolution of magnetic field rotations in rotational discontinuities (RDs) and large-amplitude Alfven wave trains (AWTs) whose initial field rotation angle \Delta Phi\ > 180 ...
Two-dimensional hybrid simulation of the dayside reconnection layer and associated ion transport
(2020-06-30)
The structure of the reconnection layer at the dayside magnetopause is studied by using a two-dimensional (2-D) hybrid code. The simulation domain is a rectangle in the at plane around an X line at the magnetopause. In our ...
