We present a dynamic nonlocal hybrid Monte Carlo algorithm consisting of pivot and “cut-and-permute” moves. The algorithm is suitable for the study of polymers in semiconfined geometries at the ordinary transition, where the pivot algorithm exhibits quasi-ergodic problems. The dynamic properties of the proposed algorithm are studied. The hybrid dynamics is ergodic and exhibits the same optimal ...

center pivot irrigation system is used as a modern irrigation method in different parts of iran. unfortunately due to lack of proper design and hydraulic shortcomings of the system in several agricultural lands in iran, the efficiency of the center pivot irrigation system is low or unacceptable. low system efficiency results in non-uniformity of water distribution along the lateral and on the c...

We prove that the principal pivot transform (also known as partial inverse, sweep operator, or exchange operator in various contexts) maps matrices with positive imaginary part to part. show is matrix monotone by establishing Hermitian square representations for and derivative.

This paper presents a work related to reordering when dealing with translation using pivot languages. Different pivot strategies are presented in order to compare their translation quality on a ChineseSpanish task. A novel method to generate reordering weights automatically for a language pair that do not share parallel corpus is presented. Experiments which show that the strategy outperforms t...

We present a new admissible pivot method for linear programming that works with a sequence of improving primal feasible interior points and dual feasible interior points. This method is a practicable variant of the short admissible pivot sequence algorithm, which was suggested by Fukuda and Terlaky. Here, we also show that this method can be modified to terminate in finite pivot steps. Finedly,...

We present a comparison of two approaches for Arabic-Chinese machine translation using English as a pivot language: sentence pivoting and phrase-table pivoting. Our results show that using English as a pivot in either approach outperforms direct translation from Arabic to Chinese. Our best result is the phrase-pivot system which scores higher than direct translation by 1.1 BLEU points. An error...

While the use of a normalized pivot structure between analysis and synthesis is a fact for many current transfer-based FAMT systems, this structure is usually tailored for one particular language-pair. The question for a "universal" pivot structure arises when the FAMT is intended to be multilingual. Such universal pivot structure (i.e., the TIS) deviates from the Interlingua approach in that i...

The pivot shift test is the only clinical test that has been shown to correlate with subjective criteria of knee joint function following rupture of the anterior cruciate ligament. The grade of the pivot shift is important in predicting short- and long-term outcome. However, because this grade is established by a clinician in a subjective manner, the pivot shift's value as a clinical tool is re...
