The aim of this study is to evaluate the relationship between patellofemoral contact stress and intraoperative knee kinematic patterns after mobile bearing total knee arthroplasty (TKA). Medial osteoarthritic knees of forty-six posterior-stabilized total knee prostheses were evaluated using a computed tomography-guided navigation system. Subjects were divided into two groups based on intraopera...

Recent research on multilingual statistical machine translation focuses on the usage of pivot languages in order to overcome resource limitations for certain language pairs. This paper provides new insights into what factors make a good pivot language and investigates the impact of these factors on the overall pivot translation performance. Pivot-based SMT experiments translating between 22 Ind...

Statistical machine translation (SMT) requires a parallel corpus between the source and target languages. Although a pivot-translation approach can be applied to a language pair that does not have a parallel corpus directly between them, it requires both source–pivot and pivot–target parallel corpora. We propose a novel approach to apply SMT to a resource-limited source language that has no par...

Similarly to lahguage aquisition, language processing faces a strong input-datadeficiency problem. When we speak we alter a great deal in the idealised phonetic and phonological representations. We delete whole phonemes, we radically change allophones, we shift stresses, we break up intonational patterns, we insert paus es in the most unexpected places, etc. If to such crippled phonological str...

The principal pivot transform (PPT) is a transformation of the matrix of a linear system tantamount to exchanging unknowns with the corresponding entries of the right-hand side of the system. The notion of the PPT is encountered in mathematical programming, statistics and numerical analysis among other areas. The purpose of this paper is to draw attention to the main properties and uses of PPTs...

While recent neural machine translation approaches have delivered state-of-the-art performance for resource-rich language pairs, they suffer from the data scarcity problem for resource-scarce language pairs. Although this problem can be alleviated by exploiting a pivot language to bridge the source and target languages, the source-to-pivot and pivot-to-target translation models are usually inde...

In this paper we introduce the concept of s-monotone index selection rule for linear programming problems. We show that several known anticycling pivot rules like the minimal index-, last-in-first-outand themost-often-selected-variable pivot rules are s-monotone index selection rules. Furthermore, we show a possible way to define new s-monotone pivot rules. We prove that several known algorithm...

In the first part of the paper we survey some far reaching applications of the basis facts of linear programming to the combinatorial theory of simple polytopes. In the second part we discuss some recent developments concurring the simplex algorithm. We describe sub-exponential randomized pivot roles and upper bounds on the diameter of graphs of polytopes. 

Triangulation in Pivot-Based Statistical Machine Translation(SMT) is a very effective method for building Machine Translation(MT) systems in case of scarcity of the parallel corpus. Phrase Table Triangulation helps in such a resource constrained setting by inducing new phrase pairs with the help of a pivot. However, it does not explore the possibility of extracting reordering information throug...
