this paper we present an image sequence coding scheme for very low bit rate coding which is based on spatial redundancy reduction via the new edge sensitive subband coding method and temporal redundancy reduction via windowed overlapped block-matching motion compensation. The scheme has the main advantage , that only the signiicant regions of diierence-images are coded. Thus the computational c...

The discrete multitone modulation (DMT) systems have been widely used in various applications. The DMT system can be considered as a dual of a subband coder, obtained by using the synthesis bank as the transmitter and analysis bank as the receiver. In designing optimal subband coders, the objective is to minimize output quantization noise, whereas in the problem of designing optimal DMT system,...

one of the common chronic inflammatory skin diseases is acne vulgaris that affects up to 80% of a teen-age population. the progress of acne lesions is due to colonization of propionibacterium acnes (p .acnes) in hair follicles. treatment of acne includes topical or systemic therapy or combination therapy, with a tendency to perform topical therapy in mild to moderate acne. nanoemulsions, small ...

Management of the diabetic foot is often problematic, particularly as the diabetic patient is prone to sub-clinical infections. This article reviews diabetic foot ulceration and its treatment and describes some of the commonly associated complications of these chronic wounds. It is proposed that highly hydrophobic dressings are of value in reducing the bacterial colonization of ulcers, and an e...

This paper describes algorithms to generate trajec-tories for diierentially at systems with zero dynamics. Zero dynamics in at systems occur when the at outputs are not the tracking outputs. This means that the output trajectories can be fully parametrized by the at outputs, but that there is some additional freedom left. This freedom can be exploited to minimize a cost criterion. We parametriz...

OBJECTIVES To evaluate and compare levels of patient discomfort and perioperative complications during phacoemulsification and implantation of a foldable intraocular lens under topical lidocaine hydrochloride and retrobulbar anesthesia in patients with cataract who also had exfoliation syndrome, uveitis, posterior synechia, phacodonesis, or previous intraocular surgery. DESIGN A prospective, ...

background: viral warts are a common problem especially in young people. they are important as they are transmittable and cause social embarrassment. though there are several treatments for viral warts, none offer a fast, simple, complete cure by itself. a simple and inexpensive way of treatment would be outstanding, especially in developing countries. we aimed to determine the efficacy and saf...

introduction: solar lentigines are among commonest cosmetic problems. there are many topical therapies suggested to treat these lesions including cryotherapy, chemical peeling with tri chloro acetic acid (tca) and laser therapy with q-switched lasers as well as long pulsed lasers. considering possible treatment side effects (pih, scar) with cryotherapy and peeling in iranian patients (darker sk...

Some aspects of executive function are thought to be dysfunctional in psychopathic individuals. We administered a small battery of neuropsychological tests (spatial alternation task, object alternation task, and Porteus Maze) to two samples of college students and obtained a measure of psychopathy via a selfreport questionnaire. Psychopathic traits were related to the tests of object alternatio...
