ABSTRACT We evaluated pulsatile dosing of clarithromycin and amoxicillin alone or combined against Streptococcus pneumoniae with various susceptibilities. When combined, pulsatile amoxicillin with clarithromycin was superior to either 8- or 12-h dosing against the intermediate strain and was identical for the susceptible strain. Pulse dosing of antimicrobials warrants further investigation.

The effect process between femtosecond laser and matter had been introduced first. Then introduce the theory of strain pulse and the experiment set up.We detect transient reflectivity change on surface of GaAs at different delayed time using femtosecond transient reflection spectroscopy.We found it was made up of three parts: original scattering process of 100fs, carriers-lattice thermal equilibrium of 1.5ps and recombination process of 500ps.

Strain Pulse

AbstractWe have developed a new technique for the study of the onset of plastic flow in thin metal films. A sub-picosecond light pulse is absorbed at the upper surface of the film. This generates a strain pulse that propagates through the film to the substrate and then back to the upper surface of the film where it is detected. When the temperature of the film is changed, there is a change in the transit time of the strain pulse. This change arises from the variation of the sound velocity with temperature, and also has a contribution from thermal stress in the film. By making accurate measurements of the transit time, we are able to identify the onset of plastic flow in the film.

Abstract The dynamics of magnetization is important in spintronics, where the coupling between phonon and magnon attracts much attention. In this work, we study the angular dependence of the coupling between longitudinal-wave phonon and magnon. We investigated the magnetization dynamics using the time-resolved magneto-optical Kerr effect, which allows measuring spin-wave resonances and the magnetic echo signal. The frequency, mode number, and amplitude of the spin-wave resonance change with the out-of-plane angle of the external magnetic field. The amplitude of the magnetic echo signal caused by the strain pulse also changes with the angle. We calculate these angular dependences based on the Landau-Lifshitz-Gilbert equation and find that the angles of the external field and magnetic moment are important factors for the phonon-magnon coupling when phonon propagates in the thickness direction under the out-of-plane magnetic field.
