... received both cancer cells and ascorbic acid. Group E was treated twice with PBS at two-day intervals, injected with S-180 cells, and then treated with high dose concentration ascorbic acid at two-day ... definite effect as an antitumor agent when adminis- trated at a high dose concentration. They reported that high dose concentrations of ascorbic acid, provided intra- venously, work...

... structures identical to those of the fabricated devices [15]. In order to evaluate the substrate and top bias-dependent channel carrier modula- tion as a function of temperature, we extracted ... demonstrated that nanorib- bon field-effect transistors can be used for stable high- temperature applications. The on-current level of the nanoribbon FETs decreases at elevated temperatures du...

... N-doped CNTs is estimated about 83 and 122 lg/cm 2 , respectively. From the resultant data, it is evident that the EC characteristics of Pt NPs on N-doped CNTs are superior to that on undoped ... 6a, the CV diagram of Pt NPs dispersed on N-doped CNTs shows the better performance compared with that of those NPs on undoped ones. In addition, Fig. 6b also reveals that the onset potential...

... jersey knit. The structure of the garment was crucial to the quality of data obtained, as its textile composition, design, and fit moderated the amount of force present between the body and the sensors. ... gar- ment-integrated context because of their ability to retain the tactile and mechanical properties of a textile-based structure. In the garment integration, the foam sensors h...

... authors declare that they have no competing interests. Authors' contributions MDB collected data, analysed results and aided manu- script writing. AJC collected data and aided manuscript writing. ... pertinent to this type of flexion contracture can be addressed via the lim- ited lateral approach. We also found that patients recov- ered quickly with an attendant short in-patient stay (...

Then the vector quantization scheme based on the distortion measure of the angle between the codevector and the downlink channel vector was adopted ... result, the role of the CSI at the transmitter (CSIT) is much more critical in MIMO downlink channels than that in point-to-point MIMO channels. The acquisition of the CSI at the trans...

... modulates the intensity of an LED. Because ACO-OFDM modulation employs intensity modulation and direct detection (IM/DD), the time-domain t ransmitted signal must be real and positive. The block diagram ... the data and any time-domain negative values are clipped at the transmitter. It is shown in [7] that the clipping does not distort the data on the odd subcarriers but does reduce the a...

... the direct method and fixed alternative method for functional equations is given in 19. The fixed alternative method can be considered as an advantage of this method over direct method in the fact that ... it is called a direct method because it allows us to construct the additive function directly from the given function f. In 2003, Radu 19 proposed the fixed point alternative method for...
