Early cluster formation during rapid cooling of an Al-Cu-Mg alloy: In situ small-angle X-ray scattering

Jean-Marie Drezet, Helena Van Swygenhoven, Patrick Schloth

The formation of Cu-Mg clusters in an Al-Cu-Mg aluminum alloy is observed by small-angle X-ray scattering during cooling. Cooling rates are choosen to mimic the different conditions obtained at the surface and in the center of large forgings. Clusters of 0 ...

NEW CONSTRAINTS ON THE FAINT END OF THE UV LUMINOSITY FUNCTION AT z similar to 7-8 USING THE GRAVITATIONAL LENSING OF THE HUBBLE FRONTIER FIELDS CLUSTER A2744

Jean-Paul Richard Kneib, Benjamin Yvan Alexandre Clement, Mathilde Jauzac, Hakim Atek, Johan Richard

Exploiting the power of gravitational lensing, the Hubble Frontier Fields (HFF) program aims at observing six massive galaxy clusters to explore the distant universe far beyond the limits of blank field surveys. Using the complete Hubble Space Telescope ob ...

Fitness of Business Models for Digital Collaborative Platforms in Clusters: A Case Study

Gianluigi Viscusi

This paper investigates the role of business models for exploiting digital options within digital clusters (that are clusters where collaboration is IT-dependent). To this aim, this research focuses on digital platforms, a specific IT artifact supporting a ...

Hawk: Hybrid Datacenter Scheduling

Willy Zwaenepoel, Anne-Marie Kermarrec, Pamela Isabel Delgado Borda, Florin Dinu

This paper addresses the problem of efficient scheduling of large clusters under high load and heterogeneous workloads. A heterogeneous workload typically consists of many short jobs and a small number of large jobs that consume the bulk of the cluster's r ...

The nongravitational interactions of dark matter in colliding galaxy clusters

David Richard Harvey, Richard Massey

Collisions between galaxy clusters provide a test of the nongravitational forces acting on dark matter. Dark matter's lack of deceleration in the "bullet cluster" collision constrained its self-interaction cross section sigma(DM)/m

Checking the Dark Matter Origin of a 3.53 keV Line with the Milky Way Center

Alexey Boyarsky, Oleg Ruchayskiy

We detect a line at 3.539 +/- 0.011 keV in the deep exposure data set of the Galactic center region, observed with the x-ray multi-mirror mission Newton. The dark matter interpretation of the signal observed in the Perseus galaxy cluster, the Andromeda gal ...

Cluster Validity Measure and Merging System for Hierarchical Clustering considering Outliers

Jean-Philippe Thiran, Devis Tuia, Volker Gass, Frank Grégoire Jean de Morsier, Maurice Borgeaud

Clustering algorithms have evolved to handle more and more complex structures. However, measures allowing to qualify the quality of such partitions are rare and only specic to certain algorithms. In this work, we propose a new cluster validity measure (CVM ...

A large-scale, in vivo transcription factor screen defines bivalent chromatin as a key property of regulatory factors mediating Drosophila wing development

Bart Deplancke, Monica Albarca Aguilera

Transcription factors (TFs) are key regulators of cell fate. The estimated 755 genes that encode DNA binding domain-containing proteins comprise similar to 5% of all Drosophila genes. However, the majority has remained uncharacterized so far due to the lac ...
