Supersymmetric relics from the big bang
Abstract We consider the cosmological constraints on supersymmetric theories with a new, stable particle. Circumstantial evidence points to a neutral gauge/Higgs fermion as the best candidate forExpand

Tests of quantum gravity from observations of γ-ray bursts
The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. HereExpand

Learning and memory deficits upon TAU accumulation in Drosophila mushroom body neurons.
Mutations in the neuronal-specific microtubule-binding protein TAU are associated with several dementias and neurodegenerative diseases. However, the effects of elevated TAU accumulation onExpand

Quantum-gravity analysis of gamma-ray bursts using wavelets
In some models of quantum gravity, space-time is thought to have a foamy structure with non-trivial optical prop- erties. We probe the possibility that photons propagating in vacuum may exhibit aExpand

Tubulin dipole moment, dielectric constant and quantum behavior: computer simulations, experimental results and suggestions.
We used computer simulation to calculate the electric dipole moments of the alpha- and beta-tubulin monomers and dimer and found those to be |p(alpha)| = 552D, |p(beta)| = 1193D and |p(alphabeta)| =Expand

We compile phenomenological constraints on the minimal low-energy effective theory which can be obtained from the superstring by Calabi-Yau compactification. Mixing with the single additional neutralExpand

Naturally Vanishing Cosmological Constant in N=1 Supergravity
Abstract For N =1 supergravity theories we show that the choice of a particular class of Einstein spaces for the Kahler manifold of the hidden sector leads to a vanishing cosmological constantExpand

Robust Limits on Lorentz Violation from Gamma-Ray Bursts
Abstract We constrain the possibility of a non-trivial refractive index in free space corresponding to an energy-dependent velocity of light: c ( E ) ≃  c 0 (1 −  E / M ), where M is a mass scaleExpand

Starobinsky-like inflationary models as avatars of no-scale supergravity
Models of cosmological inflation resembling the Starobinsky R+R2 model emerge naturally among the effective potentials derived from no-scale SU(N,1)/SU(N) × U(1) supergravity when N > 1. We displayExpand
