Dynamic Motions of Topological Defects in Nematic Liquid Crystals under Spatial Confinement

Article discusses how topological defects (TDs) have become a sensational topic due to their significant influence on the unusual optical and physiochemical characteristics of the material. Here, authors assert how nematic liquid crystals confined in a cell exhibiting surfaces with periodic anchoring conditions containing surface topography are relied on.

Post-imprinting modification: electrochemical and scanning electrochemical microscopy studies of a semi-covalently surface imprinted polymer (open access)

Post-imprinting modification: electrochemical and scanning electrochemical microscopy studies of a semi-covalently surface imprinted polymer

Authors of the article describe a post-imprinting modification of the imprinted molecular cavities for electrochemical sensing of a target protein. These mesoporous cavities were modified with a ferrocene ‘electrochemical’ tracer for electrochemical transduction of the target protein recognition.

Sibling Aggression, Feeding Rates, and Hatch Rank of Nestling Red-Shouldered Hawks (Buteo lineatus) (open access)

Sibling Aggression, Feeding Rates, and Hatch Rank of Nestling Red-Shouldered Hawks (Buteo lineatus)

Article describes how, in many raptor species, hatching asynchrony results in a size hierarchy among nestlings, which may facilitate brood reduction by means of sibling aggression-induced mortality, especially in times of low food resources. The authors studied the influence of hatch rank, brood size, and brood age on aggression and feeding rates among Red-shouldered Hawk (Buteo lineatus) nestlings in suburban southwestern Ohio.

The refractive index of a single atom experienced by a single photon (open access)

The refractive index of a single atom experienced by a single photon

Article describes how the refractive index of a system is often viewed as the collective response of a medium to an electromagnetic field. By studying the propagation of a single photon interacting with a two-level atom, the authors examine the dispersion behavior, calculate the phase and group velocity of the photon wave packet, and further analyze the dispersion experienced by the photon.
