Abstract The full-heavy tetraquarks $$cc{\bar{c}}{\bar{b}}$$ c ¯ b and $$bb{\bar{b}}{\bar{c}}$$ are systematically investigated within a quark model. meson–meson structure, diquark–antidiquark structure K-structure considered in...

Abstract Conventional synthetic methodologies mostly bar access to the fabrication of innovative silica- or metal oxide-based materials with an expanded property spectrum. However, nature represents inexhaustible source inspiration for synthesis multifunctional tailored attributes. Particularly low-energy catalytic pathways poriferan biosilicification, enzyme silicatein at their heart, have bee...

Bin-Amphiphysin-Rvs (BAR) domain proteins play essential roles in diverse cellular processes by inducing membrane invaginations or membrane protrusions. Among the BAR superfamily, the `classical' BAR and Fes/CIP4 homology BAR (F-BAR) subfamilies of proteins usually promote membrane invaginations, whereas the inverse BAR (I-BAR) subfamily generally incur membrane protrusions. Despite possessing ...

We combine radial velocities, proper motions, and low resolution abundances for a sample of 315 K and M giants in the Baade’s Window (l, b) = (0.9◦,−4◦) Galactic bulge field. The velocity ellipsoid of stars with [Fe/H] > −0.5 dex shows a vertex deviation in the plot of radial versus transverse velocity, consistent with that expected from a population with orbits supporting a bar. We demonstrate...
