Comment on the Measurement of Cosmological Birefringence
Nodland and Ralston (astro-ph/9704196) claim evidence for a wavelength-independent cosmic birefringence. Although it has been shown (astro-ph/9704247, astro-ph/9704263) that the data analysed did not support this conclusion, the possibility of such an effect remains interesting.

Designing chiral organic small molecules for circularly polarized light detection via group theory
The chiral point group determines the arrangement of the μ‐m of chiral organic small molecules, thereby influencing their chiral photoelectric properties. In particular, chiral molecules with the D2 point group can effectively align the μ‐m to be either 0° or 180°, an effective strategy for high‐performance circularly polarized light photodetectors ...

Abstract Background Sodium alendronate (ALN) is widely used to treat postmenopausal osteoporosis, but both estrogen deficiency and antiresorptive therapy may impair alveolar bone repair after tooth extraction. A clinically relevant but insufficiently explored scenario involves estrogen‐deficient individuals receiving hormone replacement therapy (HRT ...

Abstract Background Free palatal gingival grafts (FGG) are commonly harvested during mucogingival procedures. The present study investigates age‐related local and systemic early secondary wound healing outcomes, following FGG harvest in a rat model. Methods A 4.2 mm diameter defect was created in the palate of 24 younger (2 m) and 24 older (6 m) Wistar

Low birefringence measurement in polymers
Many polymer films are filled with particles to either increase the surface roughness or to increase the strength of the film. Occasionally, however, impurities are present in unfilled films and these can cause problems such as tearing.

Optical Kerr Gating as a Strategy for Noise Reduction in Femtosecond Stimulated Raman Spectroscopy
We report an experimental approach, where an Optical Kerr gate is incorporated with Femtosecond Stimulated Raman Spectrometry (FSRS). The gate functions as a temporal filter that preferentially suppresses the FSRS inherent background. FSRS spectra are reported with the Kerr‐gated methodology with significantly improved SNR compared to the conventional ...

Raman Bands of Malto‐ and Isomalto‐Oligosaccharides as Models for Starch
The present study measured Raman spectra of malto‐ and isomalto‐oligosaccharides with various degree of polymerization as models for starch. The data suggest that malto‐oligosaccharides with degree of polymerization ≥ 5 exhibit Raman bands similar to those of starch.
