Gravity-efficient motor control is associated with contraction-dependent intracortical inhibition
iScience, 2023 Summary: In humans, moving efficiently along the gravity axis requires shifts in muscular contraction modes. Raising the arm up involves shortening contractions of arm flexors, whereas the reverse movement can rely on lengthening contractions with the ...

Gravity is controlled by the cosmological constant [PDF]
Physical Review D, 2005 We discuss a Randall-Sundrum-type two D-braneworld model in which D-branes possess different values of the tensions from those of the charges, and derive an effective gravitational equation on the branes. As a consequence, the Einstein-Maxwell theory is realized together with the non-zero cosmological constant.

Running of the spectral index and inflationary dynamics of F(R) gravity
Physics Letters B, 2022 In this work we shall provide a model-independent general calculation of the running of the spectral index for vacuum F(R) gravities. We shall exploit the functional form of the spectral index and of the tensor-to-scalar ratio in order to present a ...
