Maps of average lensing parameters of simulated microlensing events due to different BFFPs over the 2D space log10−log10. Here, Fi and Fw are fractions of simulated microlensing events due to

We show the total surface flooding for a given topography as a function of Mg/Si and FeO for a 1 M⊕ planet with Earth-like molar ratios (i.e., Fe/Mg, Ca/Mg, Al/Mg).

Computational models of an R-substituted poly (phosphoric sulfonic ester). 1) S4-symmetric cyclic tetramer. 2) Hypothetical monomer unit, analogous to an amino acid in our comparison with polypeptides. — QRB Discovery

Atomic numbering of a C25 carbon molecule. — Nanomaterials (Basel) via PubMed We present a theoretical model of the hydrogenation and amination of a primal carbon cluster of the tangled

The colours indicate the temperature and transparency indicates the relative contribution to the overall observed flux at the point of maximum visibility, based on the angle between a given point

This illustration shows a red dwarf star orbited by a hypothetical exoplanet. Red dwarfs tend to be magnetically active, displaying gigantic arcing prominences and a wealth of dark sunspots. Red

Graphical Abstract — Genes (Basel) Sequences of tRNAs are highly patterned in easily identifiable RNA repeats and RNA inverted repeats (stem-loop-stems). Because of patterning, the multi-step evolution of tRNA can
