BACKGROUND We explored whether positioning patients in a 25° back-up sniffing position improved glottic views and ease of intubation. METHODS In the first part of the study, patients were intubated in the standard supine sniffing position. In the second part, the back of the operating table was raised 25° from the horizontal by flexion of the torso at the hips while maintaining the sniffing p...
This thesis presents three new low-complexity intrusion detection algorithms tested on sniffing data from 80,000 real Internet sessions. A Password Guessing Detector scans telnet connections containing only failed logins and identifies password guessing attacks based on the number of connection between each host pair and the usernames and passwords tried. By extracting the plaintext password, t...
Understanding how neural and behavioral timescales interact to influence cortical activity and stimulus coding is an important issue in sensory neuroscience. In air-breathing animals, voluntary changes in respiratory frequency alter the temporal patterning olfactory input. In the olfactory bulb, these behavioral timescales are reflected in the temporal properties of mitral/tufted (M/T) cell spi...
Inspired by the connections between social behavior and intelligence, I have developed a trainable system to phenotype mouse social behavior. This system is of immediate interest to researchers studying mouse models of social disorders such as depression or autism. Mice studies provide a controlled environment to begin exploring the questions of how to best quantify social behavior. For the pur...
The antagonism of apomorphine-induced climbing behaviour and sniffing and the swim-induced grooming test are widely used models for screening antipsychotic drugs. It is hypothesized that blockade of climbing behaviour evoked by apomorphine is related to the dopamine receptor blockade in the nucleus accumbens and antagonism of stereotyped sniffing produced by apomorphine is related to the blocka...
A key feature of mammalian olfactory perception is that sensory input is intimately related to respiration. Different authors have considered respiratory dynamics not only as a simple vector for odor molecules but also as an integral part of olfactory perception. Thus, rats adapt their sniffing strategy, both in frequency and flow rate, when performing odor-related tasks. The question of how fr...
Human sniffing behavior usually involves bouts of short, high flow rate inhalation (>300 ml/s through each nostril) with mostly turbulent airflow. This has often been characterized as a factor enabling higher amounts of odorant to deposit onto olfactory mucosa than for laminar airflow and thereby aid in olfactory detection. Using computational fluid dynamics human nasal cavity models, however, ...
