OBJECTIVES The aim of this study was to select useful items for assessing fall risk in healthy elderly Japanese individuals. METHODS A total of 965 healthy elderly Japanese subjects aged ≥60 years (349 males 70.4 ± 7.1 years, 616 females 69.9 ± 7.1 years) participated in this study. Of these, 16.6% had suffered from a previous fall. We assumed five fall risk factors: symptoms of falling, phys...

The reaction 28 Si + 181 Ta has been studied at E Lab =125 and 135 MeV. Coincidences between high energy particles and various X-and γ-rays from abnormally long-lived states were observed. e.g. 7.8-8.6 MeV α-particles with γ-rays of a superdeformed band, 5.1-5.5 MeV α-particles with X-and γ-rays of W, Re, and Pt, and 3.88 MeV particles (interpreted as protons) with 185.8 keV γ-rays. The data ar...

Artificial reverberation is an important music production tool with a strong but poorly understood perceptual impact. A literature review of the relevant works concerned with the perception of musical reverberation is provided, and the use of artificial reverberation in multisource mixes is studied. The perceived amount of total artificial reverberation in a mixture is predicted using relative ...

background dust events are common air pollution events in parts of the world in arid, semiarid, or desert areas. during the last years, air quality of kerman city has been deteriorated due to urban and industrial development as well as population growth. objective the aim of this study was to evaluate the dust fall events in kerman city. material and methods the british jar test assembly method...

The semileptonic CP asymmetry in B-B̄ mixing, asl, is measured in proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb−1, recorded by the LHCb experiment. Semileptonic B decays are reconstructed in the inclusive final states D−μþ and D −μþ, where the D− meson decays into theKþπ−π− final state and theD − meson into the D̄0ð→ Kþπ−Þπ− final state. The asymmetry between t...

In this paper we compute the radiation of the massless closed string states due to the non-vanishing coupling to the rolling open string tachyon with co-dimensions larger than 3, and discuss the effect of back reaction to the motion of the rolling tachyon. We find that for small string coupling, the tachyonic matters remain in the late time, but it will completely evaporate away over a string s...
