Automatic segmentation of the left atrium (LA) with the left atrial appendage (LAA) and the pulmonary vein (PV) trunks is important for intra-operative guidance in radio-frequency catheter ablation to treat atrial fibrillation (AF). Recently, we proposed a model-based method for LA segmentation from the C-arm CT images using marginal space learning (MSL). However, on some data, the mesh from th...

At the fluid/porous-medium interface the pseudo-Rayleigh (pR) and pseudo-Stoneley (pSt) waves exist. The relation with the corresponding poles in the slowness plane is not unambiguous, depending on the choice of branch cuts. For a point-force excitation, the far-field Green's functions are computed using vertical branch cuts (method I) implying that the pR- and pSt-poles obey the radiation cond...

In integer programming, the elementary closure associated with a family of cuts is the convex set de ned by the intersection of all the cuts in the family. In this paper, we compare the elementary closures arising from several classical families of cuts: three versions of Gomory's fractional cuts, three versions of Gomory's mixed integer cuts, two versions of intersection cuts and their strengt...

Synthetic aperture radar interferometry can obtain information on the surface of earth. In fact, accuracy phase unwrapping directly affects digital elevation model, but problem that has been puzzling people is low in high-noise regions. To solve this problem, we propose a new approach based an improved branch-cut method, which classifies branch cut. First, connect short cuts and then use networ...

Split cuts are among the most important and well-understood cuts for general mixed-integer programs. In this paper we consider some recent generalizations of split cuts and compare their relative strength. More precisely, we compare the elementary closures of split, cross, crooked cross and general multi-branch split cuts as well as cuts obtained from multi-row and basic relaxations. We present...

In theories with unstable particles, unitarity is satisfied by the inclusion of only stable states in sums. Hence cuts are not to be taken through particles. This raises a challenge generalized method, whose aim reconstruct amplitudes analyzing sets cuts. Nevertheless, under some general physical conditions, and perhaps methodological modifications, we prove that method still reliable for one-l...

The purpose of this paper is to present an overview of families of cutting planes for mixed integer programming problems. We examine the families of disjunctive inequalities, split cuts, mixed integer rounding inequalities, mixed integer Gomory cuts, intersection cuts, lift-and-project cuts, and reduceand-split cuts. In practice, mixed integer Gomory cuts are very useful in obtaining solutions ...
