Efficient Implementation of a Synchronous Parallel Push-Relabel Algorithm

Motivated by the observation that FIFO-based push-relabel algorithms are able to outperform highest label-based variants on modern, large maximum flow problem instances, we introduce an efficient implementation of the algorithm that uses coarse-grained parallelism to avoid the problems of existing parallel approaches. We demonstrate good relative and absolute speedups of our algorithm on a set of large graph instances taken from real-world applications. On a modern 40-core machine, our parallel implementation outperforms existing sequential implementations by up to a factor of 12 and other parallel implementations by factors of up to 3

Studies on genetic relationships and diversity in arecanut (Areca catechu L.) germplasm utilizing RAPD markers

In the present investigation, genetic relationship among 60 arecanut germplasm, consisting of both indigenous and exotic accessions, were assessed using 14 polymorphic RAPD primers. The average polymorphism was 6.64 markers per primer. The PIC values among the 14 primers ranged from 0.19 to 0.49. Similarity values among the accessions ranged between 0.68 and 0.93. Cluster analysis revealed two major clusters. The Indian collections Konkan I, Konkan II and Maidhan formed a separate cluster. All the collections from Indonesia, Sri Lanka, Vietnam, Fiji, Solomon Islands, Singapore and China and some Indian collections (viz., Andaman and Nicobar Islands and North East germplasm collections) formed a second cluster. The clustering pattern was, in general, in accordance with the geographical origin of the collections. The results obtained from this study are crucial for developing effective management strategies for genetic improvement of arecanut

Physical Processes in Star Formation

© 2020 Springer-Verlag. The final publication is available at Springer via https://doi.org/10.1007/s11214-020-00693-8.Star formation is a complex multi-scale phenomenon that is of significant importance for astrophysics in general. Stars and star formation are key pillars in observational astronomy from local star forming regions in the Milky Way up to high-redshift galaxies. From a theoretical perspective, star formation and feedback processes (radiation, winds, and supernovae) play a pivotal role in advancing our understanding of the physical processes at work, both individually and of their interactions. In this review we will give an overview of the main processes that are important for the understanding of star formation. We start with an observationally motivated view on star formation from a global perspective and outline the general paradigm of the life-cycle of molecular clouds, in which star formation is the key process to close the cycle. After that we focus on the thermal and chemical aspects in star forming regions, discuss turbulence and magnetic fields as well as gravitational forces. Finally, we review the most important stellar feedback mechanisms.Peer reviewedFinal Accepted Versio
