introduction: the advent of antibiotics and the improvement in dental hygiene have made the occurrence of deep neck infections less frequent than in the past. nevertheless, the complications of these infections are often life threatening. the purpose of this study was to review the clinical findings in deep neck infections and identification predisposing factors of these complications. material...

We present a novel visual place recognition method designed for operation in challenging conditions such as encountered in day to night or winter to summer matching. The proposed WxBS Retrieval method is novel in enriching a bag of words approach with the use of multiple detectors, descriptors with suitable visual vocabularies, view synthesis, and adaptive thresholding to compensate for large v...

this review gives an overview of our recent findings and developments in research on brain mechanisms of morphine reward from studies using the place preference conditioning paradigm. intracranial place conditioning methodology has become a valuable and firmly established and very widely used tool in behavioural pharmacology and drug reward mechanisms. several studies have established that morp...

Perceptual experiments on audio-visual consonant recognition based on the spectral reduction of the speech (SRS) have been carried out with coherent and incoherent (McGurk) audio-visual pairs. The main interest of SRS in four sub-bands is to have a partial suppression of the information transmitted for the place of articulation. The integration of manner, restricted to the fricative/occlusive c...

in recent years, the topic of desertification has been discussed in different ways in scientific areas. this event occurred globally, regionally and nationally and many steps were taken to stop it. desertification is challenged universally and its destructive effects are unavoidable and its consequences do endanger the life of inhabitants. the identification of sensitive regions and prevention ...

Advanced Surface Movement Guidance and Control Systems need the identification of aircraft and vehicles in airport movement area. In this work, a video identification algorithm, based on the tail number recognition, is proposed as a part of a global surveillance video system. The aircraft identification problem has to deal with three fundamental aspects: capturing and preprocessing the images, ...

Photospheric ephemeral regions (EPRs) cover the Sun like a magnetic carpet. From this, we update the Babcock – Leighton solar dynamo. Rather than sunspot fields appearing in the photosphere de novo from eruptions originating in the deep interior, we consider that sunspots form directly in the photosphere by a rapid accumulation of like-sign field from EPRs. This would only occur during special ...
