Let A be a (d + 1) d real matrix whose row vectors positively span R d and which is generic in the sense of BB arr any and Scarf BS]. Such a matrix determines a certain innnite d-dimensional simpli-cial complex , as described by BB arr any, Howe and Scarf BHS]. The group Z d acts on with nitely many orbits. Let fi be the number of orbits of (i + 1)-simplices of. The sequence f = (f0; f1; : : : ...

The scarf framework as presented [2] offers the basic equations for training SCRFs. We propose to extend the framework with Empirical Bayes Risk training or Empirical Training Error optimization, which are better correlated with the error metric one seeks to optimize, than the conditional log-likelihood normally used. Second, SCRFs are (marginalized) exponential models over segmented sequences....

" We show that, in markets with indivisibilities (typified by the Shapley-Scarf housing market), the strict core mechanism is categorically determined by three assumptions: individual rationality, Pareto optimality and strategy-proofness.

Background. The combination of Dega transililiac and femoral subtrochanteric is used in our department in the treatment of Legg-Calvé-Perthes' disease. Subtrochanteric osteotomy, initially performed as varus-derotation osteotomy, is now mainly extension osteotomy with shortening. Femoral shortening is crucial for joint decompression and makes room for pelvic redirection after pelvic osteotomy. ...

OBJECTIVE To compare postoperative maxillary stability following Le Fort I osteotomy for the correction of occlusal cant as compared with conventional Le Fort I osteotomy for maxillary advancement. STUDY DESIGN The subjects were 40 Japanese adults with jaw deformities. Of these, 20 underwent a Le Fort I osteotomy and intraoral vertical ramus osteotomy (IVRO) to correct asymmetric skeletal mor...

BACKGROUND AND PURPOSE Tibial tubercle osteotomy (TTO) is an established surgical technique for exposing the stiff kneein revision total knee arthroplasty (RTKA). The osteotomy is usually performed through the anterior metaphyseal cancellous bone of the tibia but it can be extended into the intramedullary canal if tibial stem and cement removal are necessary. Furthermore, repeat osteotomy may b...
