MIN-COST WITH DELAY SCHEDULING FOR LARGE SCALE CLOUD-BASED WORKFLOW APPLICATIONS PLATFORM
Cloud computing is a promising solution to provide the resource scalability dynamically. In order to support large scale workflow applications, we present Nuts-LSWAP which is implementation for Cloud workflow. Then, a novel Min-cost with delay scheduling algorithm is presented in this paper. We also focuses on the global scheduling including genetic evolution method and other scheduling methods (sequence and greedy) to evaluate and decrease the execution cost. Finally, three primary experiments divided into two parts. One parts of experiment demonstrate the global mapping algorithm effectively, and the second parts compare execution of a large scale workflow instances with or without delay scheduling. It is primarily proved the Nuts-LSWAP is efficient platform for building Cloud workflow environment
Study of the gluonic quartic gauge couplings at muon colliders
The potential of the muon colliders open up new possibilities for the
exploration of new physics beyond the Standard Model. It is worthwhile to
investigate whether muon colliders are suitable for studying gluonic quartic
gauge couplings~(gQGCs), which can be contributed by dimension-8 operators in
the framework of the Standard Model effective field theory, and are intensively
studied recently. In this paper, we study the sensitivity of the process
to gQGCs. Our result indicate that the muon
colliders with c.m. energies larger than can be more sensitive
to gQGCs than the Large Hadron Collider.Comment: 11 pages, 5 figure
1-[5-(2-Chlorophenyl)-5-hydroxy-3-methyl-4,5-dihydro-1H-pyrazol-1-yl]ethanone
The title compound, C12H13ClN2O2, crystallizes with two independent but very similar molecules (A and B) in the asymmetric unit. The pyrazole ring in each molecule has an envelope conformation. The dihedral angle between the pyrazole ring mean plane and the benzene ring is 86.07 (14)° in A and 85.99 (14)° in B. In the crystal, the A and B molecules are linked via a pair of O—H⋯O hydrogen bonds, forming dimers. These dimers are further linked via C—H⋯O interactions to form –A–B–A–B– chains propagating along the c-axis direction
Enhancing the Purity of Reflective Structural Colors with Ultrathin Bilayer Media as Effective Ideal Absorbers
Structural colors of high purity and brightness are desired in various applications. This study presents a general strategy of selecting the appropriate material and thickness of each layer to create high‐purity reflective colors in a classic asymmetric Fabry–Pérot cavity structure based on a dielectric–absorber–dielectric–metal multilayered configuration. Guided by the derived complex refractive index of the ideal absorber layer, an effective absorbing bilayer medium consisting of two ultrathin lossy films is used to improve the color purity of reflective colors by suppressing the reflection of its complementary colors with the enhanced optical absorption. Highly pure red, green, and blue reflective colors are designed and experimentally demonstrated employing different effective bilayer absorbers. Due to the high refractive index of the dielectric material, the colored structures exhibit great angle‐robust appearance (blue and red colors are up to ±60°, and green color is up to ±45°). The generalized design principles and the proposed method of using effective bilayer absorbers open up new avenues for realizing high‐purity thin‐film structural colors with more materials selections.A general strategy for the material and layer thickness selection to produce high‐purity reflective colors in a dielectric–absorber–dielectric–metal multilayered structure is presented. The color purity of red, green and blue reflective colors can be significantly improved by designing different effective absorbing bilayer media to enhance the optical absorption over a broad wavelength range of nontargeted colors.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151998/1/adom201900739-sup-0001-S1.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151998/2/adom201900739.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151998/3/adom201900739_am.pd
Residence of Habitat-Specific Anammox Bacteria in the Deep-Sea Subsurface Sediments of the South China Sea: Analyses of Marker Gene Abundance with Physical Chemical Parameters
Anaerobic ammonium oxidation (anammox) has been recognized as an important process for the global nitrogen cycle. In this study, the occurrence and diversity of anammox bacteria in the deep-sea subsurface sediments of the South China Sea (SCS) were investigated. Results indicated that the anammox bacterial sequences recovered from this habitat by amplifying both 16S rRNA gene and hydrazine oxidoreductase encoding hzo gene were all closely related to the Candidatus Scalindua genus. A total of 96 16S rRNA gene sequences from 346 clones were grouped into five subclusters: two subclusters affiliated with the brodae and arabica species, while three new subclusters named zhenghei-I, -II, and -III showed ≤97.4% nucleic acid sequence identity with other known Candidatus Scalindua species. Meanwhile, 88 hzo gene sequences from the sediments also formed five distant subclusters within hzo cluster 1c. Through fluorescent real-time PCR analysis, the abundance of anammox bacteria in deep-sea subsurface sediment was quantified by hzo genes, which ranged from 1.19 × 104 to 7.17 × 104 copies per gram of dry sediments. Combining all the information from this study, diverse Candidatus Scalindua anammox bacteria were found in the deep-sea subsurface sediments of the SCS, and they could be involved in the nitrogen loss from the fixed inventory in the habitat
