Convolutional Neural Networks (CNNs) are well-studied and commonly used for the problem of object detection thanks to their increased accuracy. However, high accuracy on its own says little about effective performance CNN-based models, especially when real-time tasks involved. To best our knowledge, there has not been sufficient evaluation available methods in terms speed/accuracy trade-off. Th...

INTRODUCTION Upper airway obstruction (UAO) is a major problem in unconscious subjects, making full face mask ventilation difficult. The mechanism of UAO in unconscious subjects shares many similarities with that of obstructive sleep apnea (OSA), especially the hypotonic upper airway seen during rapid eye movement sleep. Continuous positive airway pressure (CPAP) via nasal mask is more effectiv...

To assess the interference of patient care due to COVID 19 related restrictions and formulate future guidelines. This cross-sectional online survey-based study was carried out among ophthalmologist Bangladesh in early lock down period (01 April 30 April) 2020. Total 93 ophthalmologists responded study. Most were seeing patients with red eye (40.9%), ocular trauma acute infections inflammations ...

of average position error, and in the number of frames where the results outper-form the best instantaneous individual method. These result are encouraging. Acknowledgments We would like to thank researchers from the connectionnist and vision mailing list, Prof. for their help, encouragement and discussions, and for providing image sequences. tive importance of these errors, the vehicle size (i...

Motion-induced blindness (MIB) and binocular rivalry (BR) are examples of multistable phenomena in which our perception varies despite constant retinal input. It has been suggested that both phenomena relate to visual awareness and share a common underlying mechanism. We tried to determine whether experimental manipulations of the target dot and the mask systematically affect MIB and BR in a no...

laryngeal mask is a supraglothic instrument for ventilation of patients who are under anesthesia. insertion of laryngeal mask requires maintaining sufficient depth of anesthesia to avoid airway reflex (gagging, coughing and spasms). the present study investigated two techniques of anesthesia with propofol-atracurium and thiopental-atracurium to facilitate insertion of the laryngeal mask, term o...

introduction: until now, many models have been presented for optical study of the human eye. in recent years, surgery on the anterior section of the eye (such as cataract and photo-refractive surgery) has increased, so a study on the optics of the eye and evaluation of vision quality has become more important. material and methods: in this article, some of these models are considered. they incl...
