Corneal biomechanics in normal and subclinical keratoconus eyes
BMC Ophthalmology, 2023 Background The diagnosis of keratoconus, as the most prevalent corneal ectatic disorder, at the subclinical stage gained great attention due to the increased acceptance of refractive surgeries.

Resonant mode conversion in the waveguides with an unbroken and broken PT-symmetry [PDF]
, 2014 We study resonant mode conversion in the PT-symmetric multimode waveguides, where symmetry breaking manifests itself in sequential destabilization (appearance of the complex eigenvalues) of the pairs of adjacent guided modes.

Second-order corrections to slow-roll inflation in the brane cosmology
, 2004 We calculate the power spectrum, spectral index, and running spectral index for the RS-II brane inflation in the high-energy regime using the slow-roll expansion. There exist several modifications.

Measuring religious social capital: the scale properties of the Williams Religious Social Capital Index (WRSCI) among cathedral congregations [PDF]
, 2008 The theoretical construct of social capital remains contested in terms of conceptualisation and measurement. The present paper follows the convention of distinguishing between trust, bonding, bridging and linking social capital, to conceptualise how ...

Using the parcel shape index to determine arable land division types
Acta Geographica Slovenica, 2019 This paper presents a new index for determining the shape of land parcels. Parcel shapes are usually represented descriptively (i.e. ribbon-shaped, rectangular, irregularly shaped), which is useless for automated distinguishing between parcel shapes or ...
