Geometry of epimorphisms and frames
(American Mathematical Society, 2004-07)
Using a bijection between the set BH of all Bessel sequences in a (separable) Hilbert space H and the space L(ℓ2, H) of all (bounded linear) operators from ℓ2 to H, we endow the set F of all frames in H with a natural ...
Single-cell revolution unveils the mysteries of the regenerative mammalian digit tip
(2020)
The digit tip is an exciting model for studying regeneration in mammals, but the precise mechanisms and the populations of cells involved in the formation and remodeling of the blastema remain unknown. In an exciting new ...

Description of the newly-hatched juvenile of Aegla castro Schmitt, 1942 (Crustacea, Anomura, Aeglidae)
(2017-02-27)
This study describes and illustrates the morphology of the first juvenile stage of Aegla castro Schmitt, 1942. Ovigerous females were collected from May to July 2013, in Couro River (Mauá da Serra, Paraná, Brazil). These ...
The phylogenetic position of Dinogeophilus and a new evolutionary framework for the smallest epimorphic centipedes (Chilopoda: Epimorpha)
(SPB Academic Publ, 2015-09)
The centipedes of the clade Epimorpha change slightly during post-embryonic growth but there is huge variation between species in the maximum body size. New specimens of the rarely collected Neotropical genus Dinogeophilus ...
