This paper studies the announcement returns to diversifying mergers from 1950 to 2002. It is widely believed that corporate diversification destroys value, but we find that combined (bidder + target) announcement returns were significantly positive for diversifying mergers throughout the period. The return from diversifying mergers fell after the 1970s, consistent with the view that investors s...

A simple method for measuring RF plasma parameters by means of a DC-biased Langmuir probe is developed. The object of this paper is to ensure the reliability of this method by using the other methods with different principles. First, Langmuir probe current e I response on RF voltage p1 V superimposed to DC p V biased probe was examined in DC plasmas. Next, probe current response of DC biased pr...

The impact wave response of soil due to a ball drop is monitored on a 30.5 cm by 30.5 cm square soil box using a fiber sensor with dynamic strain sensing capability. The experiments are conducted in real time using a simple one-laser one-modulator configuration with stimulated Brillouin scattering. The embedded BOTDA sensor grid successfully monitored the distribution and evolution of the inner...

Pulse wave evaluation is an effective method for arteriosclerosis screening. In a previous study, we verified that pulse waveforms change markedly due to arterial stiffness. However, a pulse wave consists of two components, the incident wave and multireflected waves. Clarification of the complicated propagation of these waves is necessary to gain an understanding of the nature of pulse waves in...
