Controversy exists regarding whether violent shaking is harmful to infants in the absence of impact. In this study, our objective was to characterize the biomechanical response of the infant head during shaking through use of an instrumented anthropomorphic test device (commonly referred to as a 'crash test dummy' or infant surrogate) representing a human infant and having improved biofidelity. A series of tests were conducted to simulate violent shaking of an infant surrogate. The Aprica 2.5 infant surrogate represented a 5th percentile Japanese newborn...

At a signalized intersection, drivers must make a stop/go decision at the onset of the yellow signal. Incorrect decisions would lead to red light running (RLR) violations or crashes. This study aims to predict drivers' stop/go decisions and RLR violations during yellow intervals. Traffic data such as vehicle approaching speed, acceleration, distance to the intersection, and occurrence of RLR violations are gathered by a Vehicle Data Collection System (VDCS). An enhanced Gaussian Mixture Model (GMM) is used to extract moving vehicles from target lanes, and the Kalman Filter (KF) algorithm is utilized to acquire vehicle trajectories...

Our aim was to assess differences between men and women in the likelihood of exposure to traffic as drivers of cars and motorcycles, and in the risk of dying from a car or a motorcycle crash, in order to verify the extent to which Darwin's Sexual Selection Theory could have predicted the findings and can help to interpret them. Study population was composed of men and women aged 18 to 60 years residents in the state of Rio de Janeiro between 2004 and 2010, and in the state of Rio Grande do Sul between 2001 and 2010...

: Introduction Road traffic collisions are a common cause of injuries and injury-related deaths in sub-Saharan Africa (SSA). Basic prehospital care can be the difference between life and death for injured drivers, passengers, and pedestrians. Problem This study examined the challenges associated with current first response practices in Malawi. METHODS: In April 2014, focus groups were conducted in two areas of Malawi: Karonga (in the Northern Region) and Blantyre (in the Southern Region; both are along the M1 highway), and a qualitative synthesis approach was used to identify themes...

Accident analysis and studies on traffic revealed that cyclists' violation of red-light regulation is one typical infringement committed by cyclists. Furthermore, an association between cyclists' crash involvement and red-light violations has been found across different countries. The literature on cyclists' psychosocial determinants of red-light violation is still scarce. The present study, based on the classification of cyclists' red-light behavior in risk-taking (ignoring the red-light and traveling through the junction without stopping), opportunistic (waiting at red-lights but being too impatient to wait for green signal and subsequently crossing the junction), and law-obeying (stopping to obey the red-light), adopted an eye-observational methodology to investigate differences in cyclists' crossing behavior at intersections, in relation to traffic light violations and the presence of other cyclists...

BACKGROUND: Self-management can optimize health outcomes for individuals with chronic pain (CP), an increasing fiscal and social burden in Canada. However, self-management is rarely integrated into the regular care (team activities and medical treatment) patients receive. Health information technology offers an opportunity to provide regular monitoring and exchange of information between patient and care team. OBJECTIVE: To identify information needs and gaps in chronic pain management as well as technology features to inform the development of an Internet-based self-management program...

Education, enforcement and engineering countermeasures are implemented to make road users comply with the traffic rules. Not all the traffic rule violations can be addressed nor countermeasures be implemented at all unsafe locations, at once, due to limited funds. Therefore, this study aims at ranking the traffic rule violations resulting in crashes based on individual ranks, such as 1) frequency (expressed as a function of the number of drivers violating a traffic rule and involved in crashes), 2) crash severity, 3) total crash cost, and, 4) cost severity index, to assist transportation system managers in prioritizing the allocation of funds and improving safety on roads...

BACKGROUND: Due to increasing stress, individual personality traits are becoming a significant contributor to CRT (Crash Related Trauma). In the present study, we hypothesized that there will be no difference in personality characteristics of CRT patients and control subjects and there will be no association between trauma and personality characteristics of CRT patients. METHOD: A total of 119 cases and 112 controls of age >18 years were selected as per criteria decided...

In this study, a multivariate random-parameters Tobit model is proposed for the analysis of crash rates by injury severity. In the model, both correlation across injury severity and unobserved heterogeneity across road-segment observations are accommodated. The proposed model is compared with a multivariate (fixed-parameters) Tobit model in the Bayesian context, by using a crash dataset collected from the Traffic Information System of Hong Kong. The dataset contains crash, road geometric and traffic information on 224 directional road segments for a five-year period (2002-2006)...

Introduced plants can positively affect population viability by augmenting the diet of native herbivores, but can negatively affect populations if they are subpar or toxic resources. In organisms with complex life histories, such as insects specializing on host plants, the impacts of a novel host may differ across life stages, with divergent effects on population persistence. Most research on effects of novel hosts has focused on adult oviposition preference and larval performance, but adult preference may not optimize offspring performance, nor be indicative of host quality from a demographic perspective...

The measurement of internal magnetic fluctuation is important for the study of transport in tokamak plasmas. The runaway electron transport induced by the sawtooth crash can be used to obtain the internal magnetic fluctuation. Inversed sawtooth-like activities on hard x-ray (HXR) fluxes following sawtooth activities were observed after the application of electrode biasing on J-TEXT tokamak. The runaway diffusion coefficient Dr is deduced to be about 30 m(2)/s according to the time delay of HXR flux peaks to the sawtooth crashes...

The utilization of tranexamic acid (TXA) for the management of bleeding trauma patients has been a subject of much debate on both sides of the Atlantic and in Australia. As a result of the large randomized controlled study called the Clinical Randomization of an Antifibrinolytic in Severe Hemorrhage (CRASH-2), there was an initial enthusiasm for the use of TXA to treat bleeding patients. However, the adoption of TXA in the United States was delayed by concerns of "knowledge and evidence gaps" of the CRASH-2 study and because of a lack of mechanistic rationale that would explain the survival benefit noted in the study...

BACKGROUND: Road traffic fatalities (RTF) are among the top ten causes of deaths in the world. The risk factors for RTF fatal victims have been extensively characterized, but studies of household burden of RTF have been very few in number. Accordingly, this article investigates post-crash impacts on RTF victims' family members, including the adverse impacts of lost income, occupational disruption, unfavorable family dynamics, and residential relocation. METHODS: Survey data from 1291 RTF family members interviewed in Taiwan in 2012 provide the evidence of impact used in this article...

The objective of this study was to evaluate the effectiveness of forward collision warning (FCW) alone, a low-speed autonomous emergency braking (AEB) system operational at speeds up to 19mph that does not warn the driver prior to braking, and FCW with AEB that operates at higher speeds in reducing front-to-rear crashes and injuries. Poisson regression was used to compare rates of police-reported crash involvements per insured vehicle year in 22 U.S. states during 2010-2014 between passenger vehicle models with FCW alone or with AEB and the same models where the optional systems were not purchased, controlling for other factors affecting crash risk...

Pedestrian safety is increasingly recognized as a major public health concern. Extensive safety studies have been conducted to examine the influence of multiple variables on the occurrence of pedestrian-vehicle crashes. However, the explicit relationship between pedestrian safety and road network characteristics remains unknown. This study particularly focused on the role of different road network patterns on the occurrence of crashes involving pedestrians. A global integration index via space syntax was introduced to quantify the topological structures of road networks...

Lane departures represent an important cause of road crashes. The objective of the present study was to assess the effects of an auditory Lane Departure Warning System (LDWS) for partial and full lane departures (onset manipulation) combined with missed warnings (reliability manipulation: 100% reliable, 83% reliable and 66% reliable) on drivers' performances and acceptance. Several studies indicate that LDWS improves drivers' performances during lane departure episodes. However, little is known about the effects of the warning onset and reliability of LDWS...

Fluorogenic probes that signal the presence of specific DNA or RNA sequences are key enabling tools for molecular disease diagnosis and imaging studies. Usually, at least one fluorophore is attached via covalent bonds to an oligonucleotide probe. However, the additional conjugation step increases costs. Herein we introduce a method that avoids the requirement for the preparation of fluorescence labeled oligonucleotides and provides the opportunity to alter the fluorogenic reporter dye without resynthesis. The method is based on adjacent hybridization of two dicysteine-containing peptide nucleic acid probes to form a bipartite tetracysteine motif which binds profluorescent bisarsenical dyes such as FIAsH, ReAsH or CrAsH...
