Actinic prurigo: a retrospective analysis of 21 cases referred to an Australian photobiology clinic.
Actinic prurigo (AP) is a rare acquired idiopathic photodermatosis, reported most often in American Indians, but also in Caucasian and Asian populations. The skin lesions in AP predominantly affect exposed sites but may involve covered areas, and often result in postinflammatory scarring. The diagnosis of AP can be difficult and relies on a combination of history, clinical experience and invest...
HLA class II alleles (detected by DNA typing) were determined in 116 Caucasians with systemic sclerosis positive and negative for anticentromere autoantibodies (ACA). Significantly increased frequencies of HLA-DR5(DRw11) (P = 0.009) and the Dw13(DRB1*0403, *0407) subtypes of DR4 (probability corrected, Pc = 0.005) were seen in ACA positive patients, and HLA-DR1 and DRw8 were also increased. The...
AIM To test the psychometric properties and clinical usability of a new Pressure Ulcer Risk Assessment Instrument including inter-rater and test-retest reliability, convergent validity and data completeness. BACKGROUND Methodological and practical limitations associated with traditional Pressure Ulcer Risk Assessment Instruments, prompted a programme to work to develop a new instrument, as pa...
Center for Wireless Communications and Department of Electrical & Computer Engineering, University of California, San Diego 9500 Gilman Dr.La Jolla, CA 92093-0407, USA – fax: +1-619-534-2486 – e-mail: fzorzi,rao,[email protected] Abstract— In this paper, we investigate the behavior of block errors which arise in data transmission on fading channels. Our approach is more detailed than previ...
Current epidemiological data from the USA, Europe, Asia and the Indian subcontinent, Africa, the Far East, South America, the Middle East and Eastern Europe all point to the increasing incidence of renal failure encompassing acute kidney injury (AKI), chronic kidney disease (CKD) and endstage renal disease (ESRD). While the explanations for these worldwide epidemics remain speculative, it must ...
AIM To agree a draft pressure ulcer risk factor Minimum Data Set to underpin the development of a new evidenced-based Risk Assessment Framework. BACKGROUND A recent systematic review identified the need for a pressure ulcer risk factor Minimum Data Set and development and validation of an evidenced-based pressure ulcer Risk Assessment Framework. This was undertaken through the Pressure UlceR ...
Center for Wireless Communications, University of California San Diego, 9500 Gilman Dr., La Jolla, CA 92093-0407, USA fax: +1-619-534-2486 – e-mail: fzorzi,[email protected] Abstract— We posit that limiting performance metrics of error control protocols to throughput and delay is inappropriate when terminals are powered by a finite energy battery source. We propose the total number of correctly...
The global convergence properties of a class of penalty methods for nonlinear programming are analyzed. These methods include successive linear programming approaches, and more specifically, the successive linear-quadratic programming approach presented by Byrd, Gould, Nocedal and Waltz (Math. Programming 100(1):27–48, 2004). Every iteration requires the solution of two trust-region subproblems...
بررسی انتقال رطوبت خاک بین دو زهکش و روند تغییرات رطوبتی در محیط اطراف ریشه دارای اهمیت بسیاری میباشد. مدل HYDRUS-2D با به‌کارگیری معادلات بقای جرم، علاوه بر تسریع در نتایج، موجب کاهش هزینه‌ها می‌شود. در این مطالعه سیستم زهکشی زیرزمینی با عمق 9/0 متر و فاصله 30 متر با عمق آب زیرزمینی 50 سانتیمتر در طول فصل کشت کلزا به‌عنوان کشت دوم در اراضی شالیزاری شهرستان ساری مورد بررسی قرار گرفت. پروفیل خ...
Ranks of subspaces of vector spaces satisfy all linear inequalities satisfied by entropies (including the standard Shannon inequalities) and an additional inequality due to Ingleton. It is known that the Shannon and Ingleton inequalities generate all such linear rank inequalities on up to four variables, but it has been an open question whether additional inequalities hold for the case of five ...
