Last year at the Metropolitan Opera House, I enjoyed the opera The Nose, directed by William Kentridge. In the opera, a man named Major Kovalyov woke up one morning and found that his nose had gone missing in the night. The nose had developed a life of its own (Fig. 1). Although a police officer returned the nose to Kovalyov, a doctor was unable to reattach the nose. On 13th day after losing hi...

An enhanced time-delay neural network (TDNN), using time series sensor response data, improved pattern recognition ability of an electronic nose (e-nose) in discriminating four different spices. TDNN was used for analysis of e-nose time series sensor data from 0 to 4 min, while two popular pattern recognition methods, discriminant function analysis (DFA) and multilayer perceptron (MLP) trained ...

White-nose syndrome, associated with the fungal skin infection geomycosis, caused regional population collapse in bats in North America. Our results, based on histopathology, show the presence of white-nose syndrome in Europe. Dermatohistopathology on two bats (Myotis myotis) found dead in March 2010 with geomycosis in the Czech Republic had characteristics resembling Geomyces destructans infec...

OBJECTIVE To report the long-term efficacy of a modified extracorporeal septoplasty technique in the treatment of anterocaudal septal deviations. STUDY DESIGN Case series with chart review. SETTING Academic tertiary care medical center. SUBJECTS AND METHODS Data were obtained by a retrospective review of patients treated by a single surgeon (S.P.M.) from December 2010 to April 2014. A tot...

The IDI-MRSA assay (Infectio Diagnostic, Inc., Sainte-Foy, Quebec, Canada) with the Smart Cycler II rapid DNA amplification system (Cepheid, Sunnyvale, CA) appears to be sensitive and specific for the rapid detection of nasal colonization by methicillin-resistant Staphylococcus aureus (MRSA). We assessed the sensitivity and specificity of this assay under conditions in which both the nose and c...

This paper provides a review of the most recent works in machine olfaction as applied to the identification of Chinese Herbal Medicines (CHMs). Due to the wide variety of CHMs, the complexity of growing sources and the diverse specifications of herb components, the quality control of CHMs is a challenging issue. Much research has demonstrated that an electronic nose (E-nose) as an advanced mach...

The nose is frequently traumatized in facial injuries and this often results from motor vehicle accidents, sports-related injuries, and altercations. Subsequently, posttraumatic nasal deformity is one of the most common reasons that patients seek consultation in the doctor's office. Depending on the type of nasal deformities, this can result in functional impairment and aesthetic problems. Two ...

An improved classification of Orthosiphon stamineus using a data fusion technique is presented. Five different commercial sources along with freshly prepared samples were discriminated using an electronic nose (e-nose) and an electronic tongue (e-tongue). Samples from the different commercial brands were evaluated by the e-tongue and then followed by the e-nose. Applying Principal Component Ana...

The nose is one of the most important cosmetic units of the face. Discreet variations in the nose shape lead to marked physiognomy changes. Many patients dissatisfied with the appearance of their nose seek cosmetic improvement as early as during adolescence. Similar to other facial structures, the nose is affected by the aging process. Typically, nose tip drop is observed, along with loss of su...

Electronic noses have potential applications in daily life, but are restricted by their bulky size and high price. This review focuses on the use of chemiresistive gas sensors, metal-oxide semiconductor gas sensors and conductive polymer gas sensors in an electronic nose for system integration to reduce size and cost. The review covers the system design considerations and the complementary meta...
