Objectives: Hearing impairment in children is considered as an important public health problem. Auditory function in these children is poor and depends on their hearing aids efficacy and also their ears’ status. Hearing aids are very expensive and ear disease deteriorates its performance. Therefore detecting the ear disease and offering proper treatment is necessary. The aim of this study is to...

We propose an ear recognition system based on 2D ear images which includes three stages: ear enrollment, feature extraction, and ear recognition. Ear enrollment includes ear detection and ear normalization. The ear detection approach based on improved Adaboost algorithm detects the ear part under complex background using two steps: offline cascaded classifier training and online ear detection. ...

Nontypeable Haemophilus influenzae (NTHi) is a major pathogen causing otitis media (OM). One of the outer membrane proteins of NTHi, P6, is a common antigen to all strains and is considered a candidate for mucosal vaccine. We have previously reported that intranasal immunization with P6 and cholera toxin (CT) could induce P6-specific immunoglobulin A (IgA) antibodies in the middle ear. In the p...

Cholesteatoma is a severe non-cancerous lesion of the middle ear characterized by massive inflammation, tissue destruction, and an abnormal growth keratinized squamous epithelium. We recently demonstrated presence pathogenic stem cells within cholesteatoma tissue, unfortunately their potential roles in regulating disease-specific chronic inflammation remain poorly understood. In presented study...

due to physiological disorder, primary bud necrosis (pbn) in grapevine is a great problem in vineyards, resulting in reduced yield. primary bud necrosis (pbn) is physiological disorder resulting in the death of the primary bud. the present study conducted through a light on this critical problem in a vineyard of cisakht region. a factorial experiment with three levels of cold temperature (-10, ...

in order to study the effects of sowing date and plant density on forage yield and some morphological characteristics of corn, an experiment was conducted in gorgon research station in 2008. in this experiment two sowing date (18 april and 21 june) and six plant densities (25000, 45000, 65000, 85000, 105000, and 125000 plant per hectare) were evaluated in form of factorial experiment (2×6) with...

marginal zone lymphoma (mzl) accounts for between 5% and 17% of all non-hodgkin lymphomas (nhl). w e reported a rare case of marginal zone lymphoma presenting with bilateral ear erythema and swelling. the case was a 79-year-old man who suffered from progressive bilateral ear erythema and swelling since 2 years ago. physical examination was remarkable for erythmatous, edematous and non-tender au...

in this study, generation of the transient evoked ooacoustic emissions in human ear has been simulated using a new electroacoustic model. the method of state variables was adopted to calculate the auditory model, and numerical integration methods have been used to solve differential equations in matlab. simulation results have been compared with the real data. in this study, latency curves, fre...
