Naively, one would expect longer papers to have larger impact (i.e., to be cited more). I tested this expectation by selecting all (∼ 30, 000) refereed papers from A&A, AJ, ApJ and MNRAS published between 2000 and 2004. These particular years were chosen so papers analyzed would not be too “fresh”, but at the same time length of each article could be obtained via ADS. I find that indeed longer ...

In Analytic SSA, an approximate upper bound to the logdet term in Eq. 4 is computed (Hara et al., 2012). Without re-deriving this bound entirely, we present its final steps, which we use to obtain the bounds for KSSA and NLSSA.

In this article, we prove that the commensurability class of a closed, orientable, hyperbolic 3–manifold is determined by the surface subgroups of its fundamental group. Moreover, we prove that there can be only finitely many closed, orientable, hyperbolic 3–manifolds that have the same set of surfaces.

The paper constitutes an application of Active Noise Control (ANC) on noise from wind turbine blades and rotors. This study aims at considering the potential of using ANC on wind turbines. To this end, a review was carried out on infrasound and low frequency noise emanating from wind turbines. The basis of human interaction with low frequency noise from wind turbines and its effects are studied...
