Determining landscape parameters influencing species richness of habitat patches is one of the most important issues in conservation biology. Many previous studies have investigated the influence of habitat parameters on bird assemblages in forest patches, but studies seeking effects of oasis parameters on bird assemblages are very scarce. Karkas Protected Area is located in semi-arid zone in...
An Adaptive varying window size Recursive Weighted Median Filter [ARWMF] for removing the impulse noise in Color images is presented. The weights for the RWMF are calculated by using the median controlled algorithm. By applying Region of Interest [ROI] on selected windows the weight calculation’s efficiency can be increased and the memory will be reduced because of the ROI. In median controlled...
Noninvasive measurements of infarct size after thrombolysis with a necrosis-avid MRI contrast agent.
BACKGROUND Gadophrin-2 is a new MRI contrast agent with high affinity for necrotic myocardium. The aim of the study was to evaluate whether noninvasive measurements of infarct size after thrombolysis are possible with gadophrin-2-enhanced MRI. METHODS AND RESULTS Coronary artery thrombosis was induced in 3 groups of dogs by the copper-coil technique. Thrombolytic therapy together with aspirin...
Abstract We investigate the convergence of entire Lagrange interpolations and Hermite exponential type $$\tau $$ τ , as \rightarrow \infty xmlns:mml="http://www.w3.org/1998/Math/MathML">τ→∞ in weighted $$L^p$$ xmlns:mml="http://w...
Edge-aware smoothing is an essential tool for computer vision, graphics and photography. In this paper, we develop a new efficient local weighted average filter edge-aware smoothing. The proposed can use guidance information which permits iterative filtering process. Since the weights of depend on variance, implementation requires linear filters only, leading to $\mathcal {O}(N_{pix})$ computat...
BACKGROUND Positive patch test reactions to p-phenylenediamine (PPD) are common. PPD is used in oxidative hair dyes and is also present in dark henna temporary 'tattoos'. Cross-sensitization to other contact allergens may occur. Because subjects sensitized to PPD are at risk of clinically severe reactions upon hair dyeing, there is a need for 'current' prevalence data on PPD sensitization. OB...
