Sub-aortic (SA) aneurysms are a rare entity of variable aetiology. We report the first case of a SA aneurysm assessed using cardiac magnetic resonance imaging (MRI). A 33-year-old female with human immunodeficiency virus and on highly active antiretroviral treatment presented with syncope and dyspnoea. Clinical examination suggested moderate to severe aortic regurgitation (AR) confirmed by tran...

Mechanically adaptive electronic skins (e-skins) emulate tactition and thermoception by cutaneous mechanoreceptors and thermoreceptors in human skin, respectively. When exposed to multiple stimuli including mechanical and thermal stimuli, discerning and quantifying precise sensing signals from sensors embedded in e-skins are critical. In addition, different detection modes for mechanical stimul...

The authors advocate a modernization of the neurologic exam with regard to the evaluation of static equilibrium through the application of some easily performed and interpreted bedside maneuvers like the Clinical Test of Sensory Integration and Balance modified and the Functional Reach Test. The authors also believe that these and other assessments, such as that of the risk of falling for elder...

Although older adults with Mild Cognitive Impairment (MCI) show elevated rates of conversion to dementia as a group, heterogeneity of outcomes is common at the individual level. Using data from a prospective 5-year longitudinal investigation of cognitive change in healthy older adults (N = 262, aged 64-92 years), this study addressed limitations in contemporary MCI identification procedures whi...

Abstract Situational awareness (SA) is the most important skill required by police to effectively assess and respond encounters, including critical incidents. Incomplete or sub-optimal SA strategies can lead errors in subsequent judgement, decision-making, action, tactics use of force (UOF). Errors UOF, especially lethal force, training operational field settings, have severe consequences for l...

Schedulability Analysis (SA) approaches that are based on a priori information and use fixed execution times with constant workloads work well in many application domains and allow pre-deployment guarantees of real-time performance such as Rate Monotonic Analysis (RMA [2]). However, certain realtime applications must operate in highly dynamic environments, thereby precluding accurate characteri...

assessment tools have limitations. Techniques used to manual muscle test the SA are easy to perform but do not appear to isolate the SA [5]. ElectroMyographic Activity (EMG) and motion analysis provide researchers with isolated and detailed information but interpretation is difficult [7, 8]. Unlike other assessment tools, Ultrasound Imaging (UI) provides isolated real time visualization of musc...

Disorientation is common for endoscopists performing colonoscopy. The objectives of this study were to examine how endoscopists acquire and maintain spatial awareness or situation awareness (SA), and how SA varies as a function of available perceptual cues, and as a function of the different segments of the colon. Retrospective analysis of verbal protocols from 11 colonoscopy procedures was con...

OBJECTIVE To evaluate to what extent the modification of corneal asphericity to induce spherical aberration (SA) can improve the depth of focus and to determine whether preoperative adaptive optics assessment (Voptica SL) can predict an optimal SA value for each patient. DESIGN Comparative, prospective clinical trial with paired eye control. PARTICIPANTS Patients ≥45 years old who are hyper...
