introduction: the conventional methods of dosimetry are not capable of dosimetry in such a small volume of less than one cubic millimeter. although the polymer gel dosimetry method based on magnetic resonance imaging (mri) could achieve three dimensional dosimetry with high resolution, a spatial resolution evaluation based on gel dose modulation transfer function has not been investigated yet. ...

Background: Design of experiments is a rapid and cost-effective approach for optimization of recombinant protein production process. In our previous study, we generated a potent dual-acting fusion protein, anti-CD22 scFv-apoptin, to target B-cell malignant cell lines. In the present investigation, we report the effect of different variables on the expression levels of this fusion protein. Metho...

Sinusoidal pulse width modulation is a popular modulation for most alternating current induction motor. It only requires fewer calculations and is easy to implement. However, the shortcomings of using it are low DC voltage utilization, and poor inverter transmission capability. In recent years, there is an increasing trend and more research concentration of using space vector pulse width modula...

Nitrogen-vacancy color centers in diamond have attracted broad attention as quantum sensors for both static and dynamic magnetic, electrical, strain thermal fields, are particularly attractive sensing under pressure anvil cells. Optically-based nuclear magnetic resonance may be possible at pressures greater than a few GPa, offers an alternative to conventional Faraday-induction based detection....

Introduction: Transfusion of irradiated blood is recommended by the guidelines for cardiosurgery, cancer surgery, severe trauma and congenital immune deficient recipients. To prevent post- transfusion graft-versus-host disease (PT-GVHD), blood cells may be irradiated by gamma rays. The absorbed dose range for blood irradiation is typically 15 to 50 Gy. As the assurance that blo...

In this paper, transistor lasers (TLs) are used as an optical modulator for generation of ASK(Amplitude Shift Keying) and FSK (Frequency Shift Keying) optical signals. Our analysis is based on continuity equation, rate equations, and the theory of discontinuity of quasi-fermi level at the abrupt junction. Our simulation results indicate that, the specification of ASK and FSK optical signals, ar...

We report on a two-channel magnetometer based on non-linear magneto optical rotation in Cs buffered glass cell. The Cs atoms are optically pumped and probed by free running diode lasers tuned to the D2 line. A wide frequency modulation of the pump laser is used to produce both synchronous Zeeman optical pumping and hyperfine repumping. The magnetometer works in an unshielded environment and spu...

The optical properties of metallic nanoparticles are highly sensitive to interparticle distance, giving rise to dramatic but frequently irreversible color changes. By electrochemical modification of individual nanoparticles and nanoparticle pairs, we induced equally dramatic, yet reversible, changes in their optical properties. We achieved plasmon tuning by oxidation-reduction chemistry of Ag-A...
