Objectives: Speech is unique to humans and characterized by facial actions of ∼5 Hz oscillations of lip, mouth or jaw movements. Lip-smacking, a facial display of primates characterized by oscillatory actions involving the vertical opening and closing of the jaw and lips, exhibits stable 5-Hz oscillation patterns, matching that of speech, suggesting that lip-smacking is a precursor of speech. We tested if facial or vocal actions exhibiting the same rate of oscillation are found in wide forms of facial or vocal displays in various social contexts, exhibiting diversity among species. Materials and Methods: We observed facial and vocal actions of wild stump-tailed macaques (Macaca arctoides), and selected video clips including facial displays (teeth chattering; TC), panting calls, and feeding. Ten open-to-open mouth durations during TC and feeding and five amplitude peak-to-peak durations in panting were analyzed. Results: Facial display (TC) and vocalization (panting) oscillated within 5.74±1.19 and 6.71±2.91 Hz, respectively, similar to the reported lip-smacking of long-tailed macaques and the speech of humans. Discussion: These results indicated a common mechanism for the central pattern generator underlying orofacial movements, which would evolve to speech. Similar oscillations in panting, which evolved from different muscular control than the orofacial action, suggested the sensory foundations for perceptual saliency particular to 5-Hz rhythms in macaques. This supports the pre-adaptation hypothesis of speech evolution, which states a central pattern generator for 5-Hz facial oscillation and perceptual background tuned to 5-Hz actions existed in common ancestors of macaques and humans, before the emergence of speech. © 2017 Wiley Periodicals, Inc.

A simple analytical method was developed for the determination of 90Sr in fish bone ash samples. The adsorption behaviors of 26 metal ions on Sr Resin and AnaLig Sr-01 resin were examined. The obtained distribution coefficients show that Sr Resin has suitable selectivity. The proposed method consists of co-precipitation with calcium phosphate and purification by Sr Resin. After ingrowth, 90Y was measured using a liquid scintillation counter. The proposed method was validated by radiometric analysis of 90Sr in certified reference materials. Finally, the proposed method was applied for interlaboratory comparison. The analytical results by proposed method showed acceptable z scores. © 2017 Akadémiai Kiadó, Budapest, Hungary

Background: The scissors mode is a rotational mode of isovector character in deformed nuclei. Together with the isoscalar rotation, it is the prominent collective mode at low excitation energies. Purpose: We use a simple field theory model to investigate the role of the nucleon spin for the magnetic sum rules associated with the low-lying scissors mode. Special emphasis is put on the coupling of the spin part of the M1 operator to the scissors mode. Methods: We apply the mean-field approximation and random phase approximation to a model Hamiltonian based on a simple quadrupole-quadrupole interaction. The effects of the spin-orbit interaction are included in the mean-field Hamiltonian. Ward-Takahashi re © 2014 American Physical Society.

The renormalization of the orbital g-factor in nuclei is discussed on the basis of gauge invariance. The relation of the orbital g-factor to the integrated E1 photoabsorption cross section is reviewed, and its relation to the M1 sum rule for the scissors mode of deformed nuclei is examined. © 2010 Science China Press and Springer-Verlag Berlin Heidelberg.

This paper presents an overview of visual programming environment named Splish which enables an icon-based visual programming to develop a program which runs on a microcontroller board family called Arduino which is a popular platform for physical computing. A user program can be developed visually on a PC side, and the compiled code will be transferred to the microcontroller board so that runtime environment of Splish can execute the complied code by interpreting the machine instructions of a simple virtual stack machine. This functional distribution allows the interactive debugging when the microcontroller board is connected to a PC. Because physical computing attracts wide variety of people including non-specialists and students, the visual programming and the interactive debugging capabilities of Splish will accelerate their physical computing experiences. Splish is developed with JavaFX to achieve platform independence. © 2010 IEEE.

This paper examines the welfare impact of emission taxes and subsidies in a green market where consumers emit a pollutant through their usage of products produced by duopolists. For this purpose, we employ a discrete-continuous model including both consumer choice and usage of an environmentally differentiated product in a utility-consistent framework. The findings indicate that an emission tax is always welfare dominant over a subsidy on consumer purchases of the clean product because of its contribution to a reduction in environmental damage. It does this by both inducing firms to improve the environmental qualities of their products and by constraining consumer usage of these products. © 2011 Springer Science+Business Media B.V.

Energy Studies Review | Year: 2011

This paper attempts to measure the benefits of information about efficient usage of electric appliances consumers receive through energy conservation, using data from a Japanese experiment. In the experiment, households could easily obtain information on how to achieve efficient usage of electric appliances through a display installed at their residence. The data were used to estimate a utility-consistent, discrete-continuous model of display usage and electricity demand. Full information maximum likelihood estimates of a translog indirect utility function and electricity cost share function indicate that information provision contributed to energy conservation and to welfare improvements of consumers in the experiment.

This paper describes a supply chain simulation by using hybrid-models that combine discrete-event models and system dynamics models. The discrete-event models represent operational processes inside of supply chain, and the system dynamics models represent supply chain reactions under management circumstance. The scope is a real supply chain system with a large scale and complicated operational rules. The simulation results clarified supply chain features in a long-term manufacturing management environment. ©2010 IEEE.

Active experiments to probe hot plasma in the magnetosphere were conducted at Siple Station, Antarctica. The multistations measurements of VLF Siple signals on the ground were also conducted in Canada. The results from the Siple activeexperiments at L=5.1, the relativistic treatments, and the results obtained from the multi-stations measurements at L=4.1 showed almost similar results. The relativistic treatment of separatrix at L=5.1 theoretically indicates the total energy of trapped electron, which was estimated to be 0.315 to 16 keV (at maximum of V) by estimates of parallel resonancevelocity and wave magnetic field amplitude of 11 PT, and the effective instability depending on the weak relativistic electrons with kinetic energy 10.9 keV in the perfect resonance condition. The kinetic energy 10.9 keV is almost coincident with some results of Sonwalkar et al. [Properties of the magnetospheric hot plasma.

We summarize the history and our present understanding of nuclear magnetic moments and Gamow-Teller transitions. The roles of configuration mixing, meson exchange currents and relativistic effects are examined. Experimental evidence for the importance of tensor correlations is also discussed. © 2010 Science China Press and Springer-Verlag Berlin Heidelberg.
