We discuss a lattice fermionic formulation based on one-sided differences. The formulation is non-hermitean, has no doubling and requires an average over directions akin to the point splitting regularization. We discuss the weak coupling continuum limit, the hopping parameter expansion and the ...
A lattice action for QED is considered, where the derivatives in the Dirac operator are replaced by one–sided lattice differences. A systematic expansion in the lattice spacing of the one–loop contribution to the fermion self energy, vacuum polarization tensor and vertex function is carried out ...

Dizygotic twins with one-sided CIUE provide an interesting context to study the influence of immunogenetic differences in such cases. The main immune-cell subsets were investigated using immunohistochemistry. We identified three dizygotic twin pregnancies in which CIUE was present in only one of the ...
aWith respect to P, NEWS model predictions are consistent with numerous previous studies suggesting that particulate forms dominate P export globally [e.g.,Meybeck, 1982;Froelich, 1988]. However, this is the first time that continent-scale differences in PP:DIP ratios have been estimated. The ...

aIn the shield tunnel construction, the predicting results of Peck formula of ground settlement often differences with the measured results due to the difference of geological conditions. For marine sedimentary soft soil stratum, to carry out the revise of prediction formula in ground settlement caused...
The BNL single-type column one-sided 3D detectors have some major differences from the Trento ones: (1) the high electric field is on the sensing electrode side (pixel or strip); and (2) it can develop some high electric field along the junction column as the bias voltage increases. ...
This result depends on the fact that MATs are stable if the differences between them are measured with the recently introduced hyperbolic Hausdorff distance. In this paper, we extend the result for the one-sided stability of the MAT to a class of 3D domains called weakly injective, which ...
