Subclavian artery aneurysms are uncommon. The most common causes of these aneurysms are atherosclerosis and traumatic pseudoaneurysm. We report two cases of rare congenial left subclavian artery aneurysms. Diagnosis with aortography and...

This letter warns about the incorrect use of the popular Jarque-Berg test for normality of residuals in the case of small- and medium-size samples. It also provides a natural modification of the test that mitigates the problem. Several...

We study the existence of positive solutions of a nonlinear eigenvalue problem for a two-point boundary-value problem for a family of second-order disfocal ordinary differential equations. We apply a cone-theoretic fixed-point theorem a...

The effect of O2 upon the catalytic activity Nike Roshe Run of 40 metallic oxides in the NO-decomposition reaction has been studied by working in a closed reaction system kept wholly above 400 °C so as to minimize the formation of NO2....

Let T be a linear operator on the space of all m × n complex matrices such that the rank of T(A) is the rank of A whenever the rank of A is k. We show that there are nonsingular m × m and n × n matrices U and V respectively such that...

For HD+ a potential, that allows for the nonadiabatic effects due to its mass asymmetry, is used to study the remaining nonadiabatic effects, those common to HD+ and the homonuclear H2+ and D2+. The analysis is in terms of effective vib...

A covariant splitting of the total angular momentum of a spin particle into an orbital and a spin part is obtained by treating the Dirac equation as a subsidiary condition for the solutions of the Klein-Gordon equation of a spinor fiel...

A new pure optical system that makes it possible to transmit a two-dimensional image and its color is presented. This system uses only one high order diffraction grating and a set of silica multimode fibers. A good color (seven componen...

Both field measurements and laboratory experiments suggested that absorption of UV radiation affected Nike Free Haven 3.0 the near-millimetre wave absorption by water vapour. Experiments with different flux values and at different tempe...

List decoding of Hermitian codes is reformulated to yield an efficient and simple algorithm for the interpolation step. The algorithm is developed using the theory of Gröbner bases of modules. The computational complexity of the algori...
