A critical element of word of mouth (WOM) marketing (aka buzz marketing) is to identify central actors with high degree in the social network to serve as seeds. However, seed identification typically requires data on the full network structure, which is often unavailable. We examine WOM seeding strategies motivated by the friendship paradox to get higher degree nodes without knowing network str...

A patient presenting an unusual clinical picture was recently admitted to the New Haven Hospital. She showed definite objective evidence of involvement of the central nervous system, but other obscure signs present made an accurate diagnosis difficult. At necropsy a most unexpected lesion was found involving the base of the brain, the nerve roots, and the spinal cord. The case is of particular ...

Four patients are described in whom a follicular carcinoma developed following thyroidectomy for a benign follicular neoplasm. It is possible that the initial thyroid neoplasm was a well- differentiated follicular carcinoma which was microscopically indistinguishable from a benign adenoma. Realizing this pathologic pitfall in thyroid diagnosis, the need for meticulous examination of the pa...

Tauopathies such as Alzheimer's disease (AD) feature progressive intraneuronal deposition of aggregated tau protein. The cause is unknown, but in experimental systems trans-cellular propagation of tau pathology resembles prion pathogenesis. Tau aggregate inoculation into mice produces transmissible pathology, and tau forms distinct strains, i.e. conformers that faithfully replicate and create p...

The purpose ofthis randomized prospective study was to assess the efficacy of local radiotherapy in prevent¬ ing malignant seeding along invasive diagnostic pro¬ cedures (cytology, needle biopsy, thoracoscopy, or chest tube placement) in patients with malignant pleural mesothelioma. Forty consecutive patients with histologically proven malignant mesothelioma were enrolled. Twenty patients recei...

With the climbing costs of cotton production, producers must ensure optimal returns on their cotton crops in order to make a profit. The groundwork for a high yielding crop has to start with an accurate and efficient planting system to ensure an optimal stand. However, there are a variety of new systems and techniques to incorporate compared to the conventional system that has been used for so ...

The average effect of two cloud seeding experiments (1957-1960; 1961, 1962, and 1964) over the Santa Catalina Mountains, Arizona, on the 24-hr precipitation at Walnut Gulch, 65 miles away, was an apparent 40% loss of rainfall (P = 0.025) on seeded, as opposed to not-seeded, experimental days. Larger apparent losses, some highly significant, were found for experimental days on which Walnut Gulch...

Introduction. A critical step for the in vitro engineering of a threedimensional tissue is to initially achieve a uniform distribution of cells seeded throughout the entire scaffold. Furthermore, if autologous cells are to be used in a clinical application, cells isolated from a small biopsy must be utilized with maximum efficiency. To overcome limitations associated with the most commonly empl...

Finding a suitable seeding resolution when using superpixel segmentation methods is usually challenging. Different parts of the image contain different levels of clutter, resulting in an either too dense or too coarse segmentation. Since both possible solutions cause problems with respect to subsequent processing, we propose an edge adaptive seeding for superpixel segmentation methods, generati...

Recognizing the labor intensity of current domestic Chinese chive harvesting and need for its mechanized harvesting, a self-propelled electric harvester is designed. The machine composed control system, supporting mechanism, cutting parts, conveying clamping mechanisms, frame, collection system. It can complete feeding, cutting, transmission, binning operations at one time. has width 0.25 m whe...
