“We use an ultrafast optical pump and probe technique to
investigate the propagation of subgigahertz surface acoustic waves on a 1 mm diameter glass sphere with an aluminum coating. A fiber-based pump setup generates RSL3 concentration the surface waves and a common-path interferometer images them in the time domain over the sphere surface as they pass through the pole opposite the source of excitation. Fourier analysis allows the acoustic spectrum of the acoustic source to be extracted and waves traveling in opposite directions to be isolated. (C) 2010 American Institute of Physics.

“PURPOSE: To evaluate the safety, stability, and efficacy of the first clinical cases
of epithelial laser in situ keratomileusis (epi-LASIK) performed using a 1000 Hz excimer laser system.
SETTING: Klinikum Rechts der Isar, Munich, Germany.
METHODS: The epi-LASIK procedure was performed using MEK162 chemical structure an EpiLift microkeratome and a Wave-Light Concept System 1000 laser. Preoperatively and 1, 3, and 6 months postoperatively, a complete ophthalmic examination was performed. The examination included objective and subjective refraction, uncorrected and corrected distance visual acuities, and topography.
RESULTS: The study comprised 30 eyes of 17 patients. The mean spherical equivalent was -4.36 diopters (D) +/- 1.77 (SD) preoperatively, 0.07 +/- 0.38
D 1 month postoperatively, -0.06 D +/- 0.25 D at 3 months, and -0.05 +/- 0.24D at 6 months. Six months postoperatively, 90% of patients were within +/- 0.50 D of the intended correction and all were within +/- 1.00 D. At 3 months, 25 eyes had a clear cornea and 5 eyes had trace haze.
CONCLUSIONS: In this pilot series, the use of the 1000 Hz excimer laser did not lead to the clinical side effects that are potentially associated with the use of a high repetition rate. The safety, stability, and efficacy of the laser were high although no adjustments to the nomogram were made.”
“It is difficult to describe the taste of Processed Aconite Root (PAR) because it contains toxic compounds, and Anlotinib Protein Tyrosine Kinase inhibitor tasting poses some risk to the examiner. Therefore, there is no description of the taste of PAR in the latest Japanese Pharmacopoeia, although the taste of crude drugs has been regulated as a criterion for judgment. In this study, we revealed the objective taste of PAR by using a taste-sensing system. The PAR samples examined were classified into four types by how the samples were processed: PAR1 processed by autoclaving; PAR2-a processed by autoclaving after rinsing in salt (sodium chloride) solution; PAR2-h processed by heating after rinsing in calcium chloride solution; PAR3 processed by treating with hydrated lime after rinsing in salt solution.
