ABSTRACT The synchrotron radiation (SR) X-ray absorption fine-structure spectroscopy (XAFS) technology has been emp...

Testosterone enanthate (TE) is used by many athletes as a muscle builder. Previous studies showed that high concentration of the drug in plasma may affect the natural function of endocrine glands, specially the secretion of the adrenocortical hormones. The objective of the present study was to examine the effects of high concentration of TE on histometrical structure of adrenal cortex in male r...

We present a stable and efficient method for the Bloch-mode computation of one-dimensional grating waveguides. The approach uses the Fourier modal method and the S-matrix algorithm to remove numerical instabilities. The use of perfectly matched layers provide a high accuracy. Numerical results obtained for different lamellar grating waveguides and for both TE and TM polarizations illustrate the...

Using an asymptotic analysis, we obtain an eigenvalue equation for the general mode dispersion in Bragg fibers. The asymptotic analysis is applied to calculate the dispersion relation and the field distribution of TE modes in a Bragg fiber. We compare the asymptotic results with exact solutions and find excellent agreement between them. This asymptotic approach greatly simplifies the analysis a...

This memo defines two MIB modules and corresponding MIB Object Definitions that describe how label-switching-controlled Frame-Relay and Asynchronous Transfer Mode (ATM) interfaces can be managed given the interface stacking as defined in the MPLS-LSR-STD-MIB and MPLS-TE-STD-MIB.

We demonstrate sub-picosecond holmium-doped fiber laser mode-locked with a broadband carbon nanotube saturable absorber. Ultrashort pulse operation has been obtained for the wavelength range of 2030 – 2100 nm with output power up to 60 mW and repetition rate of 15.7 MHz. In te n s it y, 1 0 d B /d iv 212

A number of problems arise when translating any work from a written language, such as early Chinese, into twentieth century English. One such problem is the difference between the written forms of the two languages, another is the difference between the two cultures, and a third is the time which elapsed between the writing of the original work, in this instance, some time between six hundred a...

A short echo time (TE = 24 ms) semiadiabatic localization by adiabatic selective refocusing (LASER) sequence was designed and optimized for full-intensity proton magnetic resonance spectroscopy ((1) H MRS) at 4 T. The sequence was combined with VAPOR water suppression and three-dimensional outer volume suppression for improved localization and suppression of unwanted coherences. Artifact-free, ...

Localized traveling-wave pulses and holes, i.e. localized regions of vanishing wave amplitude, are investigated in a real Ginzburg-Landau equation coupled to a long-wave mode. In certain parameter regimes the pulses exhibit a Hopf bifurcation which leads to a breathing motion. Subsequently the oscillations undergo period-doubling bifurcations and become chaotic. PACS: 47.20.ky, 47.27.te, 05.45....
