This study presents a combined pneumatic seed-metering device (SMD) that could not only fill, carry, and meter seeds, but also switch quickly between seed-metering and seed-cleaning modes, and clean seeds thoroughly and rapidly. The seed-filling, seed-carrying, and seed-metering modes of the SMD were analyzed based on a theoretical kinematic model. Furthermore, a three-factor, three-level ortho...

The cloud liquid water content (CLWC) data in time and space from a total of 96 pairs of target (T) and control (C) experiments were analysed in this study to compare the responses of CLWC to hygroscopic seeding of warm clouds. Our results of various approaches taken for this analysis have indicated significant modifications in the CLWC for the T clouds as against C clouds. Analysis of changes ...

ABSTRACT At the same time and location, simultaneous time series of wave slope images and the flowfield beneath water waves were obtained using an integrated set-up including particle-tracking and wave slope instruments. By an especially developed tracking algorithm, hundreds of seeding particles can be traced automatically, measuring the flow field. At the the same location the wave-field was ...

PURPOSE Palliative gastrectomy and chemotherapy are important options for peritoneal seeding of gastric cancer. The treatment stage IV gastric cancer patient who respond to induction chemotherapy, is converted to gastrectomy (conversion therapy or conversion surgery). This study explored the clinical outcomes of gastric cancer patients with peritoneal seeding who had undergone conversion therap...

Seeding strategies for influence maximization in social networks have been studied for more than a decade. They have mainly relied on the activation of all resources (seeds) simultaneously in the beginning; yet, it has been shown that sequential seeding strategies are commonly better. This research focuses on studying sequential seeding with buffering, which is an extension to basic sequential ...

To assess prospects for early diagnosis of prion disease based on prion seeding activity in cerebrospinal fluid (CSF), we measured the activity over time in scrapie-infected hamsters by real-time quaking-induced conversion (RT-QuIC). After intracerebral inoculation, activity appeared in CSF within 1 day and plateaued weeks before the onset of clinical signs. However, after intratongue inoculati...

In traditional Genetic Algorithm, random population seeding technique is simple and efficient however the population may contain poor quality individuals which take long time to converge optimal solution. This motivates to design a population initialization technique with the features of randomness, individual diversity and good quality. In this paper, an initial work has been carried out to de...

Transcellular propagation of protein aggregates, or proteopathic seeds, may drive the progression of neurodegenerative diseases in a prion-like manner. In tauopathies such as Alzheimer's disease, this model predicts that tau seeds propagate pathology through the brain via cell-cell transfer in neural networks. The critical role of tau seeding activity is untested, however. It is unknown whether...

A study of rainfall stimulation was made with the aim of assessing its economic potential for the Natal cane belt. High variability of precipitation in both space and time makes the determination of requirements and effects of large scale seeding programmes very difficult. Evaluation of field and laboratory tests have, however, identified two conditions under which seeding could increase precip...
