QUESTIONS Can clinical prediction rules be derived for injured Australian workers with persistent musculoskeletal pain? Are they valid? DESIGN Longitudinal observational study. PARTICIPANTS 847 injured workers with persistent musculoskeletal pain undergoing rehabilitation. OUTCOME MEASURES At baseline, 12 putative predictors were measured. At 9 weeks, short-term outcomes such as pain (vis...

An on-line rule tuning grey prediction fuzzy control system is present in this paper, which contains the advantage of the grey prediction, fuzzy theory and the on-line tuning algorithm. The on-line rule tuning grey prediction fuzzy control system structure is constructed so that the rise time and the overshoot of the controlled system can be maintained simultaneously. Keyword: Grey predictor, F...

in this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. mechanical properties of micro and nano- composites, including tensile strength, elongation, and young’s modulus, before and after ageing, were determined and analyzed. for this purpose, micro- and nano-sized caco3 particles were used as fillers to prepare micro-composites (c...

CONTEXT Given radiation- and sedation-associated risks, there is uncertainty about which children with head trauma should receive cranial computed tomography (CT) scanning. A high-quality and high-performing clinical prediction rule may reduce this uncertainty. OBJECTIVE To systematically review the quality and performance of published clinical prediction rules for intracranial injury in chil...

OBJECTIVES Recently, a rule was developed to predict sick leave related to shoulder pain during a period of 6 months after patients have consulted a general practitioner for a new episode of shoulder pain. The objective was to evaluate the generalizability of this prediction rule by testing it in two other populations of workers who had gone for a consultation in primary care for a new episode ...

During reading, monolingual readers actively predict upcoming words from sentence context. Here we investigated whether bilingual readers predict sentence final words when they read in their second language. We recorded event-related potentials while English monolinguals (L1 comprehenders) and late Spanish–English bilinguals (L2 comprehenders) read sentences ending in an expected or unexpected ...
