Gender differences in loudness perception may be linguistically influenced
Previous studies have reported gender differences in loudness perception. To clarify factors that affect loudness perception of men and women, so that differences in their processing of auditory stimuli might be revealed, we conducted four experiments ...

Influence of the atomic-scale inhomogeneity of the pair interaction on extracted from the STM spectra characteristics of high-$T_c$ superconductors [PDF]
The influence of the atomic-scale inhomogeneities of the pairing interaction strength on the superconducting order parameter and the conductance spectra measurable by STM is studied in the framework of weak-coupling BCS-like theory for two-dimensional ...

Large-to small-scale dynamo in domains of large aspect ratio: kinematic regime [PDF]
The Sun’s magnetic field exhibits coherence in space and time on much larger scales than the turbulent convection that ultimately powers the dynamo. In this work, we look for numerical evidence of a large-scale magnetic field as the magnetic Reynolds ...

Modeling the plasmasphere to topside ionosphere scale height ratio
A new model of plasmasphere to topside ionosphere scale heights ratio is developed, based on topside electron density (Ne) profiles deduced from the International Satellites for Ionospheric Studies (ISIS)-1 satellite measurements.

Large-scale age-dependent skewed sex ratio in a sexually dimorphic avian scavenger. [PDF]
Age-dependent skewed sex ratios have been observed in bird populations, with adult males generally outnumbering females. This trend is mainly driven by higher female mortality, sometimes associated with anthropogenic factors.
