Seeding strategies have a major influence on the success of viral marketing campaigns, but previous studies using computer simulations and analytical models produced conflicting recommendations about the optimal seeding strategy. We therefore compare four different seeding strategies in two complementary small-scale field experiments as well as in one real-life viral marketing campaign that inv...

With the popularity of BitTorrent-like P2P applications, improving its performance has been an active research area. Super-seeding, a special upload policy for the initial seeder, improves the efficiency in producing multiple seeds and reduces the uploading bytes of content initiators, thus being highly expected as a promising solution for improving downloading performance while decreasing uplo...

the aim of this research was determination of nutritive value of cressa cretica with gas test method, in vivo digestibility and degradability with nylon bag method in three phenological stages. the amount of crude protein decreased significantly in seeding stage. but the amount of ndf and adf increased in seeding stage. the degradability of dry matter and rapid and slowly degradable fractions d...

This research studies the optimal seeding of a network of consumers who are potential adopters of a technology. This problem has a wide range of applications which include launching a network good, inducing network-based marketing, igniting collaboration in organizations, and stimulating R&D with local spillovers. I have two main results so far. The first result shows that when a firm is unawar...

Neoplastic seeding may arise after radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). A low risk of seeding after RFA (0-1.1%) has been reported, which may rise up to 2.5% if ablation followed diagnostic biopsy. Needle track seeding presents with one or multiple rounded nodules along the needle track located within the peritoneum, along the abdominal muscles, which were penetrate...

to study response of bread wheat cv. sardari to row spacing and seeding rate and to determine the desirable seed density under cold rain-fed conditions a two-year study (2008 and 2009) was carried out in qamloo research station located in kurdistan. a strip plot design with three replications was used. four rows spacing including 15, 17.5, 20 and 25 cm as horizontal factor and four seeding rate...

BACKGROUND/AIMS Needle-track seeding is a rare but important complication of diagnostic and therapeutic ultrasound (US)-guided procedures in hepatocellular carcinoma (HCC). We examined the frequency of needle-track seeding after US-guided percutaneous ethanol injection (PEI), fine-needle aspiration biopsy (FNAB), and percutaneous transhepatic biliary drainage (PTBD) in order to determine the ap...

Due to their net warming effect, cirrus clouds play a crucial role in the climate system. A recently proposed climate engineering mechanism (CEM) intends to reduce high cloud cover by seeding cirrus clouds with efficient ice nuclei (IN) and therefore cool climate. Here, the susceptibility of cirrus clouds to the injection of ice nuclei in the upper troposphere is investigated in the extended Co...

Cardiovascular Diseases To the Editor: We read with interest the review by Nugent and Edelman.1 The authors have discussed seeding of prosthetic vascular graft but have not commented on the difference between single-stage and two-stage seeding. Single-stage seeding involves extraction of endothelial cells (ECs), coating of graft lumen, and implanting the graft into the patient, all within the t...

BACKGROUND/AIMS To review the effectiveness of intra-arterial chemotherapy for advanced intra-ocular retinoblastoma with vitreous and/or subretinal seeds in naive (untreated) and previously treated eyes. METHODS Retrospective study, approved by the institutional review board, of 76 eyes of 67 patients with retinoblastoma with subretinal and/or vitreous seeding treated with intra-arterial chem...
