Pion-Nucleon Phase Shifts in Heavy Baryon Chiral Perturbation Theory
, 1997 We calculate the phase shifts in the pion-nucleon scattering using the heavy baryon formalism. We consider phase shifts for the pion energy range of 140 to $200 $ MeV. We employ two different methods for calculating the phase shifts - the first using the

Twisted Alexander Polynomials and Representation Shifts
, 2007 For any knot, the following are equivalent. (1) The infinite cyclic cover has uncountably many finite covers; (2) there exists a finite-image representation of the knot group for which the twisted Alexander polynomial vanishes; (3) the knot group admits ...

Exact phase shifts for atom interferometry
, 2002 In the case of an external Hamiltonian at most quadratic in position and momentum operators, we use the ABCD formulation of atom optics to establish an exact analytical phase shift expression for atom interferometers with arbitrary spatial or temporal ...

, 2016 We calculated the magnetic dipole hyperfine interaction constants and the electric field gradients of $2p^53p~^2[3/2]_2$ and $2p^53s~^2[3/2]^o_2$ levels of Ne I by using the multiconfiguration Dirac-Hartree-Fock method.

, 2001 A simple ordinary differential equation is derived governing the red-shifts of wave-fronts propagating through a non-stationary spherically symmetric space-time. Approach to an event horizon corresponds to approach to a fixed point; in general, the phase

MAKING MEANING USING SYSTEMIC FUNCTIONAL LINGUISTICS AND VISUAL GRAMMAR ANALYSIS: COMPARISON OF SOURCE TEXT AND TARGET TEXT REFLECTED IN THE MAIN CHARACTER OF GRAPHIC NOVEL V FOR VENDETTA [PDF]
, 2017 This research presents a project designed to investigate a systemic way of analyzing metafunctions’ shifts between source texts and target texts using systemic functional linguistic (SFL) collaborated with visual grammar (VS; systemic functional ...

Voltage-tunable lateral shifts of ballistic electrons in semiconductor quantum slabs
, 2009 It is investigated that the lateral shifts of the ballistic electrons transmitted through a semiconductor quantum slabs can be negative as well as positive, which are analogous to the anomalous lateral shifts of the transmitted light beam through a ...

Projecting shifts in thermal habitat for 686 species on the North American continental shelf
PLoS ONE, 2018 Recent shifts in the geographic distribution of marine species have been linked to shifts in preferred thermal habitats. These shifts in distribution have already posed challenges for living marine resource management, and there is a strong need for ...

Topography induced optical spectral shifts and finite size effect of focal spot
, 2010 We observe topography induced spectral shifts using high resolution grating spectrometers which we attribute to the fact that the focal spot has a finite size.
