This paper is concerned with transfer characteristics of a pneumatic micrometer system with a negative feedback transducer. The system has two negative feedback pathes. One of them is based on the transfer characteristics of the feedback transducer which is introduced to linealize the transfer characteristic of the system and the other is caused by repulsive pressure force between nozzle and it...

Our purpose is to explore whether anti-dsDNA antibody, which was demonstrated to enter living cells and induced apoptosis, could adversely affect reproductive outcomes. A total of 259 women receiving the in vitro fertilization-embryo transfer (IVF) cycle were enrolled in this study, including 52 women with positive ANA and anti-dsDNA (ANA+/anti-dsDNA+ group), 86 women with positive ANA and nega...

Aims. We present a new formal solution of the Lagrangian equation of radiative transfer that is useful in solving the equation of radiative transfer in the presence of arbitrary velocity fields. Methods. Normally a term due to the inclusion of the wavelength derivative in the Lagrangian equation of radiative transfer is associated with a generalised opacity. In non-monotonic velocity fields, th...

In this article, additional discussions on the nonlinear entropy transfer between turbulence and zonal flows are given for the isotope ion mass effects on the trapped-electron-mode (TEM) driven turbulent transport shown in Ref. 1. Spectral analyses with the triad entropy transfer function reveal that the case with heavier isotope ions indicates a relatively smaller negative transfer (from zonal...

Using the fractal space-time theory (scale relativity theory), the dynamics of the fluid/nano-particle interface was analyzed. In the general case, the heat transfer through the interface reproduces a d.c. or an a.c. Josephson effects of thermal type, while in the linear approximation, the standard form of heat transfer is given. Consequently, a negative differential thermal conductance appears...

[1] We have analyzed very high frequency lightning mapping observations and remote magnetic field measurements to investigate connections between lightning morphology and impulse charge moment change (iCMC) of negative cloud-to-ground (CG) strokes with high estimated peak currents. Four lightning morphologies are identified for a total of 2126 strokes within optimum detection range of the North...

A novel clt locus required for efficient transfer of the Streptomyces phaeochromogenes plasmid pJV1 was identified and mapped. The clt region was functional in both orientations, and its absence caused a severe reduction in plasmid transfer. Chromosome mobilization, on the other hand, was not affected by absence of the clt locus. The clt region showed structural, but not sequence, similarity to...
