Quantitative magnetic force microscopy on permalloy dots using an iron filled carbon nanotube probe
Magnetic Force Microscopy tip-induced magnetization iron lled carbon nanotube
2010/11/17
We have characterized a new Magnetic Force Microscopy (MFM) probe based on an iron lled
carbon nanotube (FeCNT) using MFM imaging on permalloy (Py) disks saturated in a high magnetic
eld perpendic...
We study a defect system of two parallel D5 probe branes in a large-Nc D3 background. Using the non-abelian DBI action, we study three di erent elds that can give rise to a superconducting phase tran...
Big Bang Nucleosynthesis as a Probe of New Physics
Big bang nucleosynthesis early Universe abundances of light elements ex-tensions of the Standard Model dark matter
2010/11/16
Big bang nucleosynthesis (BBN), an epoch of primordial nuclear transforma-tions in the expanding Universe, has left an observable imprint in the abundances of light elements. Precision observations of...
The power spectrum of the residual rotation curve velocity as a probe of past mergers
Galaxy Astrophysics (astro-ph.GA)
2010/12/27
According to the $\Lambda CDM$ cosmological framework, galaxies underwent multiple mergers in their history. In this paper we propose to use the power spectrum of the residual fluctuations of the rota...
Combining cluster observables and stacked weak lensing to probe dark energy: Self-calibration of systematic uncertainties
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We develop a new method of combining cluster observables (number counts and cluster-cluster correlation functions) and stacked weak lensing signals of background galaxy shapes, both of which are avail...
Quantum metrology to probe atomic parity nonconservation
Quantum metrology probe atomic parity nonconservation
2010/10/29
An entangled state prepared in a decoherence free sub-space together with a Ramsey type measurement can probe parity violation in heavy alkali ions like Ba+ or Ra+. Here we propose an experiment with ...
Derivation of quantum master equation with counting fields by monitoring a probe
Derivation quantum master equation counting fields monitoring a probe
2010/10/21
We show a microscopic derivation of a quantum master equation with counting terms which
describes the electron statistics. A localized spin behaves as a probe whose precession angle monitors the net ...
A signature of the dark energy equation of state may be observed in the shape of voids. We estimate the constraints on cosmological parameters that would be determined from the ellipticity distributio...
Determination of Water Content in Organic Solvents by Naphthalimide Derivative Fluorescent Probe
Determination Water Content in Organic Solvents Naphthalimide Derivative Fluorescent Probe
2010/9/13
A new fluorescence dye, N-amino-4-(2-hydroxyethylamino)-1,8-naphthalimide (AHN), based on 4-bromo-1,8-naphthalic anhydride was synthesized as a fluorescence probe for determining water content in orga...
L-Cysteine-capped CdTe Quantum Dots as a Fluorescence Probe for Determination of Cardiolipin
L-Cysteine-capped Determination Cardiolipin
2010/9/15
This paper described the investigation of surface-modified quantum dots (QDs) as a fluorescence probe for the detection of cardiolipin. A single-step method for preparation of non-toxic and photo-stab...
Microlensing as a probe of the Galactic structure; 20 years of microlensing optical depth studies
microlensing dark matter Galactic structure
2010/3/19
Microlensing is now a very popular observational astronomical technique. The investigations accessible through this effect range from the dark matter problem to the search for extra-solar planets. In ...
Response of the Nevzorov hot wire probe in clouds dominated by droplet conditions in the drizzle size range
Nevzorov hot wire probe clouds droplet conditions drizzle size range
2010/2/8
During the airborne research mission ASTAR 2004 (Arctic Study of Tropospheric Aerosols, Clouds and Radiation) performed over the island of Svalbard in the Arctic a constant-temperature hot-wire Nevzor...
DEPTH INTERVALS AND TOPSOIL MOISTURE MEASUREMENT WITH THE NEUTRON DEPTH PROBE
DEPTH INTERVALS TOPSOIL MOISTURE MEASUREMENT NEUTRON DEPTH PROBE
2009/10/29
From measurements and calculations using a depth probe, the relative
response is estimated for soil layers of different thicknesses. For a 10 cm
thick layer of soil with the instrument centre in the...
Influence of angular momentum on evaporation residue cross section as a probe of nuclear dissipation
nuclear dissipation evaporation residue cross section angular momentum Langevin equation
2009/8/14
By calculating the excess of the evaporation residue cross sections of the 200Pb
nucleus over that predicted by the standard statistical model as a function of nuclear viscosity coefficient using a L...
