How to get vornoi seeds from a given diagram?
Best insight from top research papers
To obtain Voronoi seeds from a given diagram, various approaches can be employed based on the specific requirements of the application. One method involves placing seed points on small spheres centered at input vertices and arranging them into circles around each half-edge, with mirroring across associated triangles to generate Voronoi faces conforming to the input complex . Another technique involves calculating a dynamic Voronoi Diagram where seeds move over time, utilizing algorithms like the dynamic Jump Flooding Algorithm (dJFA) for real-time computation of dynamic Voronoi diagrams in particle simulations . Additionally, parallel computational geometry algorithms can be utilized to calculate discrete Voronoi diagrams, especially in scenarios where one of the seeds is removed, leveraging the availability of processors per pixel for efficient computation .

What are the benefits of seed papers?5 answersSeed papers offer various benefits across different fields. They enable labor-saving in seeding work for immature vegetables through hydroponic culture. In the scientific realm, seed papers play a crucial role in identifying influential papers, termed as 'seed' papers, using quantitative metrics based on co-citation network analysis. Moreover, seed papers facilitate sensitive allergen detection by providing a method for nucleic acid extraction from plant seed allergens using paper-based microfluidics, enhancing detection specificity and repeatability. Additionally, seed vigor assessment is streamlined through the development of rapid tests using urinary sugar analysis paper, aiding in the selection of high-quality seeds for agronomic and horticultural crops. Furthermore, the utilization of printed paper waste as a peat substitute in growing media enhances sustainability in agriculture by partially replacing peat and improving growing media characteristics for seedling production.
Does the structure of seeds influence the rate of aggregation of amyloid?5 answersThe structure of seeds can influence the rate of amyloid aggregation. A study by Sinha et al. found amyloid-like signatures in the protein storage bodies of seed sections, suggesting the presence of amyloid structures. Additionally, the study showed that the amyloid signature diminished in germinating seeds, indicating the degradation of these structures. Another study by Huang et al. evaluated the inhibition activity of compounds isolated from hawthorn seeds on Aβ1-42 aggregation. Compounds 5 and 6 showed stronger inhibition of Aβ1-42 aggregation than curcumin. These findings suggest that the structure of seeds, as well as compounds derived from seeds, can impact the rate of amyloid aggregation.
What are the molecular mechanisms that underlie the formation of seed shape?5 answersSeed shape formation is controlled by complex molecular networks involving transcription factors and metabolic pathways. The MADS-domain proteins SEEDSTICK (STK) and GORDITA (GOA) as well as the AUXIN RESPONSE FACTOR 2 (ARF2) play crucial roles in seed coat development, which determines seed size and shape. These transcription factors regulate cell expansion, cell proliferation, and the production of proanthocyanidins in the seed coat. Additionally, hormonal signals, particularly gibberellin (GA) and abscisic acid (ABA), are involved in seed development and germination. ABA regulates seed maturation, including dormancy, storage compound accumulation, and desiccation tolerance. The interplay between these hormones and transcription factors, along with the coordination of gene networks, is essential for seed formation and shape determination.
What are the importance of seed parameter in generation of random numbers?4 answersThe seed parameter is important in the generation of random numbers because it determines the initial state of the random number generator and influences the unpredictability and complexity of the generated numbers. The selection of the seed can be time varied based on commands received from a host, enhancing the unpredictability and complexity for secure data cryptography. The choice of the initial seed values is important in generating good random numbers, as it affects the full period, uniformity, and independence of the random number generator. In one approach, the seed value is computed by subjecting variable data to a Secure Hashing Algorithm, and the unpredictable number is generated using the seed value as a counter value in the random number generator. The seed parameter plays a crucial role in ensuring the quality and security of random number generation.
How to detect impurities of been seed by Nir spectroscopy?2 answersNear-infrared spectroscopy (NIRS) can be used to detect impurities in bean seeds. NIRS technology has been widely used in various fields, including agriculture. It offers advantages such as rapid speed, high efficiency, and non-destructive testing. The application of NIRS in seed quality detection has been reviewed, and it has shown promising results. NIRS can identify the content of moisture, starch, protein, fatty acids, carotene, and trace organic compounds in seeds. Additionally, NIRS can be used to predict impurities in cocoa shell powder, which is a by-product of the cocoa industry. Furthermore, NIRS has been successfully used to monitor the quality of argan seeds, including the fatty acid composition of argan seed oil, seed moisture content, seed oil content, and oil stability index. Although NIRS has limitations in accurately predicting the content of melamine in milk, it can be used to differentiate between certified milk samples and adulterated milk samples.
Can we identify plant by its seeds?5 answersYes, plant identification can be done using seeds. A field guide by Cornejo and Janovec provides a key for identifying Amazonian plants to genus level based on seed characteristics. The guide includes color photographs of seeds from 512 genera in 132 families, along with descriptions and geographical distribution information. The key uses easily recognizable characteristics such as seed size, shape, color, and surface to identify the genera. Testing the key, it was found that the majority of genera can be identified by comparing up to five seed images. While the field guide has some shortcomings, such as the lack of a genus index and the need to use multiple books for complete identification, it is still a valuable resource for identifying Amazonian plant seeds.
