On the volume conjecture for classical spin networks math.GT gr-qc hep-th math.CO We prove an upper bound for the evaluation of all classical SU(2) spin networks conjectured by Garoufalidis and van der Veen. This implies one half of the analogue of the volume conjecture which they proposed for classical spin networ...

Limits on Nonstandard Forces in the Submicrometer Range hep-ex We report the search for a nonstandard force by measuring the Casimir forces in the 0.48--6.5 $\mu$m range. By comparing the data and the theory of the Casimir force, we have obtained constraints for the parameter $\alpha$ of the Yukawa-type deviations ...
