Fat or Fit: What Is More Important?

Fat or Fit: What Is More Important?

The prevalence of obesity is increasing worldwide, and obesity represents one of the major health hazards (1). Obesity was shown to be linked to an increased mortality and morbidity. However, obesity is often associated with modifications of physical activity level. Physical activity level itself affects the health status of the individual and thus may be a confounding variable in the obesity-m...

Fat tails and non-linearity in volatility models: what is more important?

Since the seminal works of Engle [7] and Bollerslev [3] about heteroskedastic return series models, many extensions of their (G)ARCH models have been proposed in the literature. In particular, the functional dependence of conditional variances and the shape of the conditional distribution of returns have been varied in several ways (see [1] and [5] for an extensive overview). These two issues h...

Native topology or specific interactions: what is more important for protein folding?

Fifty-five molecular dynamics runs of two three-stranded antiparallel beta-sheet peptides were performed to investigate the relative importance of amino acid sequence and native topology. The two peptides consist of 20 residues each and have a sequence identity of 15 %. One peptide has Gly-Ser (GS) at both turns, while the other has d-Pro-Gly ((D)PG). The simulations successfully reproduce the ...

Averageness or symmetry: which is more important for facial attractiveness?

Effects of averageness and symmetry on the judgment of facial attractiveness were investigated using a generalized Procrustes method and multiple regression analyses. Participants (n=114) rated attractiveness of 96 photographs of faces with neutral expressions. Through a generalized Procrustes method, the faces and their mirror-reversed versions were represented as points on a hyperplane. Both ...
