Rethinking the pan scan in stable trauma: A comparison of whole-body computed tomography and selective imaging in clinically stable blunt force trauma.

Objective: To compare the frequency of clinically significant missed injuries in clinically stable trauma patients undergoing initial whole-body computed tomography (WBCT) versus selective imaging. Secondary objectives include comparisons of radiation exposure, incidental findings, ED length of stay (LOS), hospital LOS and mortality.

Methods: We performed a retrospective cohort study of trauma activations at a tertiary trauma centre in patients with normal vital signs from 1st January 2022 to 31st December 2022.

Individual differences in the distributional learning and overnight consolidation of the Mandarin level-falling tone contrast.

In perceptual studies, musicality and pitch aptitude have been implicated in tone learning, while vocabulary size has been implicated in distributional (segment) learning. Moreover, working memory plays a role in the overnight consolidation of explicit-declarative L2 learning. This study examines how these factors uniquely account for individual differences in the distributional learning and consolidation of an L2 tone contrast, where learners are tonal language speakers, and the training is implicit.

Evaluation of Major Physical and Mechanical Properties of Trembling Aspen Lumber.

Trembling aspen () is one of the major species within , a predominant genus of hardwoods in North America. However, its utilization has been limited to pulp and paper or wood-based composite boards. This study aimed at evaluating the major physical and mechanical properties of trembling aspen lumber, with an ultimate objective of using this species to produce engineered wood products (EWPs).

Distributional Learning and Overnight Consolidation of Nonnative Tonal Contrasts by Tonal Language Speakers.

Purpose: Previous studies have reported the success of distributional learning for adult speakers across segmental and suprasegmental categories immediately after training. On the other hand, second language (L2) perception models posit that the ease with which learners perceive a nonnative speech contrast depends on the perceptual mapping between the contrast and learners' first language (L1) categories. This study examined whether a difference in perceptual mapping patterns for different L2-Mandarin tonal contrasts might result in a difference in distributional learning effectiveness for tonal speakers and whether an interval of sleep enhanced the knowledge through consolidation.
