Integration of bilateral sensory information is fundamental to stimulus localization in auditory systems and depth perception in vision, but the role of stereo olfactory cues remains obscure. Here it is shown that blind, eastern American moles combine serial sampling with bilateral nasal cues to localize odorants. Blocking one nostril causes moles to err in the direction of the open nostril wit...

The ability to breath through the nose can be increased above normal by dilating the narrow nasal valve area with the plastic nasal device Nozovent. For 10 nights, 10 patients used Nozovent every other night, and the sleeping partners of the patients judged the snoring sound level using a snoring score. The results showed a significant decrease in snoring, from moderate to slight, when Nozovent...

A 72-year-old man presented with shortness of breath and vomiting of three weeks’ duration. Vomiting occurred without warning and consisted of undigested food. On the morning of this presentation, he awoke with food remnants in his nostrils and persistent coughing. The patient reported progressive difficulty with swallowing solids and liquids. He had occasional shortness of breath, constipation...

subject of special fascination ever since their first description was greeted by Western scientists with great scepticism (Home, 1802). Many thought that the platypus was a clever hoax perpetrated by careful attachment of a duck-bill and webbed feet to the skin of a mammal (Griffiths, 1998). Perhaps a greater mystery concerned the ability of a platypus to catch half its body mass of benthic inv...

Particle inhalation from the ambient environment and particle deposition in the respiratory tracts are numerically investigated using an integrated breathing human manikin which includes detailed facial features as well as nasal cavity, laryngopharynx and trachea. Visualized and quantitative results including the airflow field, particle tracks and particle inhalation and deposition patterns are...

Feature points for image correspondence are often selected according to subjective criteria (e.g. edge density, nostrils). In this paper, we present a general, non-subjective criterion for selecting informative feature points, based on the correspondence model itself. We describe the approach within the framework of the Bayesian Markov random field (MRF) model, where the degree of feature point...

The behavior of airborne particles in the human respiratory system is closely related to local tissue dosimetry and its associated health risks. inhalation these known be origin lung diseases, such as cancer, chronic obstructive pulmonary disease, cardiovascular disease. To compensate for difficulty experiments involving volunteers, silico studies using numerical models have been adopted promis...

We describe adaptations for a semiaquatic lifestyle in the dinosaur Spinosaurus aegyptiacus. These adaptations include retraction of the fleshy nostrils to a position near the mid-region of the skull and an elongate neck and trunk that shift the center of body mass anterior to the knee joint. Unlike terrestrial theropods, the pelvic girdle is downsized, the hindlimbs are short, and all of the l...

In this paper we present a non-intrusive model-based gaze tracking system. The system estimates the 3-0 pose of a user’s head by tracking as few as six facial feature points. The system locates a human face using a statistical color model without any mark on the face and then finds and tracks the facial features, such as eyes, nostrils and lip corners. A full perspective model is employed to m ...

Introduction The purpose to this work is to review systematically the morphological changes of the nostrils of patients undergoing surgery for correction of cleft lip and identify in the literature the issues involved in the evaluation of surgical results in this population. Review of Literature A review was conducted, searching for clinical evidence from MEDLINE. The search occurred in January...
