BACKGROUND The aim of this study was to examine the application of the Eschmann tracheal tube introducer (ETTI) with 4 types of supraglottic airway devices (SADs) using a child-manikin. METHODS A total of 79 paramedics were asked to exchange the 4 SADs for an endotracheal tube with the ETTI in 3 different scenarios using a randomized crossover study format: normal airway without chest compres...

A synthetic air data system (SADS) is an analytical redundancy technique that crucial for unmanned aerial vehicles (UAVs) and used as a backup during sensor failures. Unfortunately, the existing state-of-the-art approaches SADS require GPS signals or high-fidelity dynamic UAV models. To address this problem, novel airspeed estimation method leverages deep learning unscented Kalman filter (UKF) ...

We examine differential validity of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) diagnoses assessed by the fully-structured Composite International Diagnostic Interview Version 3.0 (CIDI) among Latino, non-Latino Black, and non-Latino White adolescents in comparison to gold standard diagnoses derived from the Schedule for Affective Disorders and Schizophren...

OBJECTIVE This study tests the suggestion of earlier studies concerning the importance of genetic factors in the etiology of winter seasonal affective disorders (SADs) and subsyndromal winter SAD (S-SAD). METHOD Two study populations of Winnipeg, Manitoba residents were canvassed: 250 adults of wholly Icelandic descent and 1000 adults of non-Icelandic descent. We distributed the Seasonal Patt...

Hawking radiation remains a crucial theoretical prediction of semi-classical gravity and is considered one the critical tests for model quantum gravity. However, Hawking’s original derivation used field theory on fixed background. Efforts have been made to include space–time fluctuations arising from quantization dynamical degrees freedom itself study effects particles. Using analysis, we scala...

Using the monodromy method we calculate the asymptotic quasinormal (QN) frequencies of an electromagnetic field moving in D-dimensional Schwarzschild and Schwarzschild de Sitter (SdS) black holes (D ≥ 4). For theD-dimensional Schwarzschild anti-de Sitter (SadS) black hole we also compute these frequencies with a similar method. Moreover, we calculate the electromagnetic normal modes of the D-di...

Background and aims: Social capital, by encouraging people to collaborate engage in social interactions, has been considered as an effective factor for development of mental disorders. In the preset study, we aimed investigate relationship between different aspects capital psychiatric disorders children adolescents. Methods: This study was conducted 2016 2017 Kohgiloyeh Boyer-Ahmad province, Ir...

Species abundance distributions (SADs) are widely used as a tool for summarizing ecological communities but may have different shapes, depending on the currency used to measure species importance. We develop a simple plotting method that links SADs in the alternative currencies of numerical abundance and biomass and is underpinned by testable predictions about how organisms occupy physical spac...

BACKGROUND While ethnic diversity is increasing in many Western countries, access to youth mental health care is generally lower among ethnic minority youth compared to majority youth. It is unlikely that this is explained by a lower prevalence of psychiatric disorders in minority children. Effective screening methods to detect psychiatric disorders in ethnic minority youth are important to off...
