a proper subclass of the bases for Demuth randomness, and hence of the strongly jump traceable sets. (4) The c.e. sets Turing below each ω 2 -computably approximable Martin-Löf random set satisfy a new  ...  We use Demuth randomness to study strong lowness properties of computably enumerable sets, and sometimes of ∆ 0 2 sets. (1) A set A ⊆ N is called a base for Demuth randomness if some set Y Turing above  ...  Downey and Greenberg [6] showed that in fact each strongly jump traceable set, c.e. or not, is K-trivial.

Vertebrate animals exploit the elastic properties of their tendons in several different ways.  ...  Thirdly, tendon elasticity affects the control of muscles, enhancing force control at the expense of position control. ᮊ  ...  Tendon has low energy dissipation, returning in an elastic recoil approximately 93% of the work previously done stretching it, and dissipating only 7% as heat.  ...

The jump hierarchy in the enumeration degrees

Hristo A. Ganchev, Mariya I. Soskova, Benedikt Löwe
2018 Computability - The Journal of the Assosiation  
We show that all levels of the jump hierarchy are first order definable in the local structure of the enumeration degrees.  ...  On the other hand we already saw that Γ(A) ≤ e X, so by monotonicity of the jump operation Γ(A) ≤ e X .  ...  All degrees in the interval (0 e , b] have the same jump as a and one of them is bounded by a total low n degree, hence a is low n .  ...
