Severe acute respiratory syndrome coronavirus-2 (SAR-CoV-2) is a highly contagious infectious disease and spreads through aerosols and fomites.Health care personnel who are at the forefront of the fight against coronavirus disease-19 (COVID-19) pandemic are also at greater risk of contracting the infection.Mixing of uninfected people with infected
Tsunamigenic megathrust earthquakes along the Cascadia subduction zone present a major hazard concern.We can better prepare to model the earthquake source in a rapid manner by imbuing fault geometry constraints based on prior knowledge and by evaluating the capabilities of using existing GNSS sensors.Near-field GNSS waveforms have shown promise in
In this paper, we use evidence from our earlier review of surgical randomised controlled trials with a placebo arm to show that blinding in trials TABLE of interventional procedures is feasible.We give examples of ingenious strategies that have been used to simulate the active procedure and to make the placebo control indistinguishable from the act
Partial oculosympathetic palsy followed by ischemic manifestations in brain or retina are the main symptoms of extracranial internal carotid artery (ICA) dissection.Unusually, cranial nerves may be affected.Isolated oculomotor nerve palsy is found only rarely.CASE: We present a 50-year-old nondiabetic man who experienced acute onset of right occipi
