Refractometric sensitivity of Bloch surface waves: perturbation theory calculation and experimental validation.

The sensitivity of one-dimensional Bloch surface wave (BSW) sensors to external refractive index variations using Kretschmann's configuration is calculated analytically by employing first-order perturbation theory for both TE and TM modes. This approach is then validated by comparison with both transfer matrix method simulations and experimental results for a chosen photonic crystal structure. Experimental sensitivities of (8.

Influence of fears of compassion on body image shame and disordered eating.

Purpose: The current study tested a path model examining the impact of fears of compassion in the adoption of disordered eating and whether social safeness and body shame would mediate this relationship.

Methods: Participants were 645 women (aged between 18 and 55) from the general community, who completed an online survey.

Results: Results indicated that fears of compassion were negatively associated with one's ability to feel secure and safe within close relationships, and positively linked with higher levels of body shame and disordered eating.
