On the Existence Problem of Finite Bases of Identities in the Algebras of Recursive Functions
Моделирование и анализ информационных систем, 2020 Raphael Robinson showed that all primitive recursive functions depending on one argument, and only they could be obtained from two functions s(x) = x +1 and q(x) = x - [√x]² by using operations of addition +, superposition ∗ and iteration i.

Heterotropic regulation and negative homotropic cooperativity
FEBS Open Bio, EarlyView.We identified a structural module common to some proteins that couple negative cooperativity with heterotropic regulation, two features that rarely coexist. These proteins are ring‐like and present an ordered asymmetry whereby noncontacting subunits are symmetric, and their tertiary structure differs from that of contacting subunits.

Acta Crystallographica Section E: Crystallographic CommunicationsThe title compounds, C23H22O4, (I), and C24H24O5, (II), differ in the presence of a methoxy group instead of a hydrogen atom between two methoxy groups attached to the phenyl ring of the phenyl acetate moiety, which affects not only the symmetry and ...

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank
FEBS Open Bio, EarlyView.Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum
FEBS Open Bio, EarlyView.Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Can laptops be left inside passenger bags if motion imaging is used in X-ray security screening?
Frontiers in Human Neuroscience, 2013 This paper describes a study where a new X-ray machine for security screening featuring motion imaging (i.e. 5 views of a bag are shown as an image sequence) was evaluated and compared to single view imaging available on conventional X-ray screening ...

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...
