Recent developments in dispersion compensation devices allow the upgrade of standard single mode fibers (G.652) based transmission systems to 40 Gbit/s or even higher bit rates per channel. Nevertheless, the nonlinear behavior of the fiber presents a serious limitation factor, in terms of the total achievable distance, even for single channel systems. Nonlinear intra-channel effects in high-spe...
Liver fluke infection caused by O. viverrini remains a major public health problem in Thailand particularly Northeastern and Northern region (Kaewpitoon et al., 2008b; Sitthithaworn et al., 2012; Kaewpitoon et al., 2015f). A nationwide survey in Thailand found that the prevalent was 5.1%. The highest of prevalent was found in the northeast (9.2%) and followed by the north region (5.2%) (Wongsar...
INVESTIGATION OF ADDITIONAL LOSSES OF FIBER-OPTIC CONDUCTORS OF TYPE G-652 THAT OCCUR DURING BENDING
One of the problems modern information transmission systems is introduction new methods protecting transmitted over fiber-optic lines. Currently, unauthorized access are emerging, which being improved and developed every year. Within framework this work, studies additional losses during bending optical fiber were carried out in order to create an automatic control system for that occur mechanic...
The last two decades have seen considerable efforts directed towards making electronic health records interoperable through improvements in medical ontologies, terminologies and coding systems. Unfortunately, these efforts have been hampered by a number of influential ideas inherited from the work of Eugen Wüster, the father of terminology standardization and the founder of ISO TC 37. We here s...
For living deep-tissue imaging, the optical window favorable for light penetration is in near-infrared wavelengths, which requires fluorescent proteins with emission spectra in the near-infrared region. Here, we report that a single mutant Ser28His of mNeptune with a near-infrared (≥650 nm) emission maxima of 652 nm is found to improve the brightness, photostability, and pH stability when compa...
