On the sensitivity of the diffusion MRI signal to brain activity in response to a motor cortex paradigm
Alberto De Luca, Lara Schlaffke, Jeroen CW Siero +2
Diffusion functional MRI (dfMRI) is a promising technique to map functional activations by acquiring diffusion-weighed spin-echo images. In previous studies, dfMRI showed higher sp…
CMB statistics in noncommutative inflation
Tomi S. Koivisto, David F. Mota
Noncommutative geometry can provide effective description of physics at very short distances taking into account generic effects of quantum gravity. Inflation amplifies tiny quantu…
Towards a Resolution of the Cosmological Singularity in Non-local Higher Derivative Theories of Gravity
Tirthabir Biswas, Tomi Koivisto, Anupam Mazumdar
One of the greatest problems of standard cosmology is the Big Bang singularity. Previously it has been shown that non-local ghostfree higher-derivative modifications of Einstein gr…
Phase space quantization and Loop Quantum Cosmology: A Wigner function for the Bohr-compactified real line
Christopher J. Fewster, Hanno Sahlmann
We give a definition for the Wigner function for quantum mechanics on the Bohr compactification of the real line and prove a number of simple consequences of this definition. We th…
A locally finite model for gravity
Gerard 't Hooft
Matter interacting classically with gravity in 3+1 dimensions usually gives rise to a continuum of degrees of freedom, so that, in any attempt to quantize the theory, ultraviolet d…
A Theory of Scalar Mesons
G. 't Hooft, G. Isidori, L. Maiani +2
We discuss the effect of the instanton induced, six-fermion effective Lagrangian on the decays of the lightest scalar mesons in the diquark--antidiquark picture. This addition allo…
