This paper explores a novel approach to interactive user-guided image segmentation, using eyegaze information as an input. The method includes three steps: 1) eyegaze tracking for providing user input, such as setting object and background seed pixel selection; 2) an optimization method for image labeling that is constrained or affected by user input; and 3) linking the two previous steps via a...

Many substances in the tall fescue/endophyte association (Schedonorus arundinaceus/Epichloë coenophiala) have biological activity. Of these compounds only the ergot alkaloids are known to have significant mammalian toxicity and the predominant ergot alkaloids are ergovaline and ergovalinine. Because synthetically produced ergovaline is difficult to obtain, we developed a seed extraction and par...

Digitalis davisiana, commonly called Alanya foxglove, from Turkey, is an important medicinal herb as the main source of cardiac glycosides, cardenolides, anthraquinones, etc. It is also known in the Indian Medicine for treatment of wounds and burns. It has ornamental value as well. Overexploitation of D. davisiana has led this species to be declared protected, and thereby encouraged various met...

the oxidative stability of margarine supplemented with different concentrations of fennel (foeniculum vulgare) seed extract (fse) was compared to the synthetic antioxidants; butylated hydroxyanisole (bha) and butylated hydroxytoluene (bht) at legal concentrations. the experiment was carried out under accelerated storage conditions for 4 weeks employing peroxide value (pv), p-anisidine value (av...

some safer strategies were designed and evaluated for management of apical leaf curling (chilcv) in chilli capsicum annum l. and its vectors. the strategies were designed emphasizing on the repellent crop theory and the components like physical barrier, adult-trapping, plant sanitation, foliar application of phytochemicals and minimal application of synthetic organic pesticide. the crop was inf...

A time-constrained viral marketing campaign allows a business to promote a product or event to social network users within a certain time duration. To perform a time-constrained campaign, existing works select the duration of the campaign, and then a set of k seeds that maximize the spread (expected number of users to which the product or event is promoted) for the selected duration. In practic...

Given a noisy or sampled snapshot of an infection in a large graph, can we automatically and reliably recover the truly infected yet somehow missed nodes? And, what about the seeds, the nodes from which the infection started to spread? These are important questions in diverse contexts, ranging from epidemiology to social media. In this paper, we address the problem of simultaneously recovering ...

Introduction: Radiation therapy planning (RTP) is one of the clinical applications in which both CT scan and MRI are used. MR and CT images are applied to determine the target volume and calculation of dose distribution, respectively. In addition, using two imaging modalities increases the department workload and cost. In this study, an algorithm was presented to create synthet...

The survival times of Mycoplasma gallisepticum (Mg) and Mycoplasma synoviae (Ms) on washed and unwashed natural and synthetic kanekalon hair samples over a 5-d period were evaluated using the color changing unit method for comparison with results of previous studies conducted on natural hair. Regardless of whether synthetic or natural hair samples prewashed with a disinfectant shampoo were spik...

White lupin (Lupinus albus L.) is a promising crop to meet the rising global demand for plant-based protein. The seed-borne pathogen Colletotrichum lupini, however, threatens cultivation worldwide. Seed dressings using synthetic fungicides were shown effective reduce infection levels, but their negative environmental impact and exclusion from organic production calls more sustainable solutions....
