In vitro detection of apoptosis using superparamagnetic iron oxide nanoparticles and molecular magnetic resonance imaging
(2010)
Superparamagnetic iron oxide (SPIO) nanoparticles have the potential to greatly expand current anatomical imaging techniques, specifically MRI. SPIO nanoparticles targeted to phosphatidylserine (PS) have the potential to ...
Degenerate four wave mixing in biased semiconductor superlattices
(2001)
Includes material on semiconductor Bloch equations, the Wannier-Stark ladder and Bloch oscillation theory. It also develops the equations of motion which allow calculation of the DFWM signal for biased semiconductor ...
Optically-excited excitonic states in semiconductor superlattices
(2002)
An efficient method for calculation of the exciton states in type-I superlattices is developed and
demonstrated. The model, based on the work of Dignam & Sipe [Phys. Rev. B 43,4097 (1991)],
includes bound and quasi-continuous ...
Curvature-density functional theory of shape transformation in vesicles of two-component lipid systems
(2006)
The shape transformations and composition variation of two-component model
lipid membrane isolated vesicles are studied. These are studied as aggregates in low
concentration solutions so that the vesicles are isolated ...
Positron/electron annihilation via the two-photon pathway
(2012-11-10)
When a positron/electron pair annihilate via the two-photon pathway, the emitted photons are momentum correlated. This correlation ensures that they move along a straight line path in opposite directions. An experiment ...
Effects of selected mountain bike front suspension forks on handlebar vibration and ground reaction forces
(1997)
The purpose of this investigation was to compare the effectiveness of two types of
mountain bike front fork suspension systems for controlling ground reaction vibration at
the handlebar upon impacting a raised surface. ...
Measurement of Rabi oscillation in a spin system
(2018)
This work proposes that during the application of an on-resonance MR-
pulse there exists a Rabi oscillating fi eld which can be directly measured
from a nuclear spin system. These oscillations have been previously ...
Amorphous selenium (a-Se) avalanche photodetector for applications in positron emission tomography (PET)
(2011)
Although avalanche amorphous selenium (a-Se) is a very promising photoconductor for a variety of imaging applications, it is currently restricted to applications with electron beam readout. This is performed with a vacuum ...
Theory and Production of Hyperpolarized Xenon Gas
(2015-12-03)
Conventional magnetic resonance imaging (MRI) modality is based on the magnetization
that is formed by the influence of a strong polarizing magnetic field on the spin of protons,
typically those of water molecules within ...
Hydrostatic pressure effect on the Gunn threshold electric effect in n-InSb
(1978)
The Gunn effect as a function of pressure has been
studied in n~type InSb. The Gunn threshold field is found to
decrease with increasing pressure reaching a minimum at P ~ 9
kbars. It then increases while the oscillations ...
