State of the art statistical machine translation systems are typically trained by symmetrizing word alignments in two translation directions. We introduce a new method that improves word alignment results, based on self learning using the initial symmetrized word alignments results. The method involves aligning words and symmetrizing alignments, generating labeled training data, and construct a...

Soon after the discovery of x-rays by Roentgen, radioactivity by Becquerel, and radium by the Curies, it was concluded that x-rays could not only be used for diagnostic purposes but also for therapy [1,2]. In the early years of radiation therapy, physicians had little understanding or knowledge of the physical nature and biological effects of radiation, the delivered doses were not certain, the...

When evaluating the quality of Rheumatology specialty training, it can be useful to explore similarities and differences between countries. In this article we compare the training in the UK and Poland. The two training programmes are similar in length and in the competencies that must be achieved, although they do have significant differences in the way the training is structured. The UK-based ...

in descriptive statistics, there are two computational algorithms for determining the variance s2, of a set of observations : algorithm 1: s2= - , algorithm 2: s2= , where . it is interesting to discuss, which of the above formulas is numerically more trustworthy in machine numbers sets. i this paper, based on total effect of rounding error, we prove that the second algorithm is better than ...

Co-training is a semi-supervised learning paradigm which trains two learners respectively from two different views and lets the learners label some unlabeled examples for each other. In this paper, we present a new PAC analysis on co-training style algorithms. We show that the co-training process can succeed even without two views, given that the two learners have large difference, which explai...

The present study aimed to describe heart rate (HR) responses during a simulated Olympic boxing match and examine physiological parameters of boxing athletes. Ten highly trained Olympic boxing athletes (six men and four women) performed a maximal graded exercise test on a motorized treadmill to determine maximal oxygen uptake (52.2 mL · kg(-1) · min(-1) ± 7.2 mL · kg(-1) · min(-1)) and ventilat...

Performance of elite athletes depends on their technical, physiological and psychological abilities. Different sports require various levels of aerobic, anaerobic, speed, power, agility, and strength capacities. Elite athletes and athletes who aim to become elite usually train year-round with carefully designed training programs. The close monitoring of physical capacities during the entire tra...

This paper explores the ways in which ward rounds can be conducted to maximize educational opportunities, as part of a project to improve the effectiveness of on-the-job training (OJT) for hospital doctors. Ninety ward rounds taken by 24 trainers in the Anglia region were observed. Each observation produced a note of the ward round's structure and routines and of the contributions made to it by...
