A CMOS Bio-Impedance Measurement System
(IEEE Computer Society, 2009)
This paper proposes a new method for bio-impedance measurement useful to 2D processing of cell cultures. It allows to represent biological samples by using a new impedance sensing method, and exploiting the electrode-to-cell ...

A comprehensive analysis of the peroxiredoxin reduction system in the Cyanobacterium Synechocystis sp. strain PCC 6803 reveals that all five peroxiredoxins are thioredoxin dependent
(2009)
Cyanobacteria perform oxygenic photosynthesis, which gives rise to the continuous production of reactive oxygen species, such as superoxide anion radicals and hydrogen peroxide, particularly under unfavorable growth ...

Stationarity, ergodicity, and entropy in relativistic systems
(European Physical Society, 2009)
Recent molecular-dynamics simulations show that a dilute relativistic gas equilibrates to a Jüttner velocity distribution if ensemble velocities are measured simultaneously in the observer frame. The analysis of relativistic ...

Accurate dynamic-feedback CMOS cross-quad suitable for low-voltage operation
(2009)
This paper presents the implementation of a crossquad circuit suitable for low-voltage operation. The proposed cell exploits a dynamic positive feedback gm boosting technique to achieve linear voltage-to-current conversion, ...

Astrophysical S17(0) factor extraction from breakup of 8B on 58Ni at energies near the Coulomb barrier
(The American Physical Society, 2009)
We have performed continuum-discretized coupled channels (CDCC) calculations of the breakup of 8B on 58Ni and direct proton transfer for the 8B+58Ni system at laboratory energies of 20-28.4 MeV. The influence of the 7Be ...

Changing the physical and chemical properties of titanium oxynitrides TiN1-x Ox by changing the composition
(American Physical Society, 2009)
The stability and structural properties of titanium oxynitrides, TiN1-x Ox, of different compositions are theoretically analyzed by means of first-principles periodic density-functional calculations. We show that at ...

High catalytic activity of Au/CeO x/TiO 2(110) controlled by the nature of the mixed-metal oxide at the nanometer level
(National Academy of Sciences, 2009)
Mixed-metal oxides play a very important role in many areas of chemistry, physics, materials science, and geochemistry. Recently, there has been a strong interest in understanding phenomena associated with the deposition ...

Solitons in quasi-one-dimensional Bose-Einstein condensates with competing dipolar and local interactions
(2009)
We study families of one-dimensional matter-wave bright solitons supported by the competition of contact and dipole-dipole (DD) interactions of opposite signs. Soliton families are found, and their stability is investigated ...

Theory of (d,p) and (p,d) reactions including breakup: Comparison of methods
(The American Physical Society, 2009)
There is an increasing interest in studying transfer reactions to probe the nuclear structure of exotic nuclei. For these loosely bound systems, the role of the continuum needs to be well understood. In this study, we ...
