Spin Polarizabilities of the Nucleon from Polarized Low Energy Compton Scattering

open access: yes, 2003
As guideline for forthcoming experiments, we present predictions from Chiral Effective Field Theory for polarized cross sections in low energy Compton scattering for photon energies below 170 MeV, both on the proton and on the neutron.

Measurement of the LT-asymmetry in \pi^0 electroproduction at the energy of the \Delta (1232) resonance

open access: yes, 2006
The reaction p(e,e'p)pi^0 has been studied at Q^2=0.2 (GeV/c)^2 in the region of W=1232 MeV. From measurements left and right of q, cross section asymmetries \rho_LT have been obtained in forward kinematics \rho_LT(\theta_\pi^0=20deg) = (-11.68 +/- 2 ...

Gamma-Ray Emission Concurrent with the Nova in the Symbiotic Binary V407 Cygni

open access: yes, 2010
Novae are thermonuclear explosions on a white dwarf surface fueled by mass accreted from a companion star. Current physical models posit that shocked expanding gas from the nova shell can produce X-ray emission but emission at higher energies has not ...

Valence transition in the periodic Anderson model

open access: yes, 2006
A very rich phase diagram has recently been found in CeCu$_{2}$Si$_{2}$ from high pressure experiments where, in particular, a transition between an intermediate valence configuration and an integral valent heavy fermion state has been observed.

Nylon 6, 12/Cloisite 30B Electrospun Nanocomposites for Dental Applications [PDF]

open access: yesЖурнал Сибирского федерального университета: Серия Биология, 2016
In this study, nylon-nanoclay fibers were prepared by electrospinning. The electrospun membranes were characterized by fourier transform infra red spectroscopy (FTIR), electron microscopy, X-ray diffraction studies (XRD), contact angle and differential ...

12-in-1: Multi-Task Vision and Language Representation Learning [PDF]

open access: yesComputer Vision and Pattern Recognition, 2019
Much of vision-and-language research focuses on a small but diverse set of independent tasks and supporting datasets often studied in isolation; however, the visually-grounded language understanding skills required for success at these tasks overlap ...
