To assess the longitudinal association between fall history reported at a driver's license screening visit and the likelihood of subsequent vehicle crashes. A total of 1,127 older adults were recruited from Maryland State Motor Vehicle Administration sites and interviewed annually over 15 years. Individuals who reported a previous fall were more likely to be female, perform worse on physical functioning and divided attention tasks, and report more situational driving avoidance compared with non-fallers at baseline. Females who reported a fall at baseline had a 2.6× greater likelihood of subsequently reporting a crash over the 15 years than males. Among those who reported a fall at baseline, greater weekly driving exposure over the 15 years was associated with a 23% higher likelihood of a subsequent crash. These findings support the utility of investigating nontraditional driver screening methods to identify drivers who may be at increased risk of future driving difficulties.

Silicon carbide (SiC) metal oxide semiconductor field-effect transistors (MOSFETs) are a future trend in traction inverters in electric vehicles (EVs), and their thermal safety is crucial. Temperature-sensitive electrical parameters' (TSEPs) indirect detection normally requires additional circuits, which can interfere with the system and increase costs, thereby limiting applications. Therefore, there is still a lack of cost-effective and sensorless thermal monitoring techniques.

The aim of this paper was to reduce the current spikes in battery-powered saw motors by designing and implementing a sliding mode model-following adaptive controller. The proposed controller reduces overcurrent consumption, improves system energy efficiency, and effectively maximizes battery runtime, especially under high-load conditions. By applying nonlinear compensation techniques, the controller can ensure smooth motor operation, reduce mechanical stress, and prolong tool life.

Roadway mortality increased during COVID-19, reversing a multi-decade downward trend. The Fatality Analysis Reporting System (FARS) was used to examine contributing factors pre-COVID-19 and in the COVID-19 era using the five pillars of the Safe System framework: (1) road users; (2) vehicles; (3) roadways; (4) speed; and (5) post-crash care. Two study time periods were matched to control for seasonality differences pre-COVID-19 ( = 1725, 1 April 2018-31 December 2019) and in the COVID-19 era ( = 2010, 1 April 2020-31 December 2021) with a three-month buffer period between the two time frames excluded.

Background: Midfoot fractures in polytrauma patients are often an underappreciated injury relative to their other major injuries sustained. In this study, our aim was to explore the mechanisms and patterns of injury in polytrauma related midfoot fractures as compared to single limb injuries.
Setting: Multicentre observational study.

Purpose: Equal level trauma centers in the same country might have significant differences regarding their demographics and types of trauma. Understanding geographic variations in injury patterns are essential for optimal care. Here we describe the differences in injury patterns and associated outcomes of thoracic trauma patients between rural and urban level-II trauma centers in a single country.
