From Physics Model to Results: An Optimizing Framework for Cross-Architecture Code Generation [PDF]

open access: yes, 2013
Starting from a high-level problem description in terms of partial differential equations using abstract tensor notation, the Chemora framework discretizes, optimizes, and generates complete high performance codes for a wide range of compute ...

Efficient Algorithms for Distributed Detection of Holes and Boundaries in Wireless Networks [PDF]

open access: yes, 2011
We propose two novel algorithms for distributed and location-free boundary recognition in wireless sensor networks. Both approaches enable a node to decide autonomously whether it is a boundary node, based solely on connectivity information of a small ...

Applied constant gain amplification in circulating loop experiments [PDF]

open access: yes, 2009
The reconfiguration of channel or wavelength routes in optically transparent mesh networks can lead to deviations in channel power that may impact transmission performance.

Astrophysical implications of GW190412 as a remnant of a previous black-hole merger [PDF]

open access: yes, 2020
Two of the dominant channels to produce merging stellar-mass black-hole binaries are believed to be the isolated evolution of binary stars in the field and dynamical formation in star clusters.

Erbium dopants in silicon nanophotonic waveguides [PDF]

open access: yes, 2020
The combination of established nanofabrication with attractive material properties makes silicon a promising material for quantum technologies, where implanted dopants serve as qubits with high density and excellent coherence even at elevated ...

On the black hole from merging binary neutron stars: how fast can it spin? [PDF]

open access: yes, 2013
The merger of two neutron stars will in general lead to the formation of a torus surrounding a black hole whose rotational energy can be tapped to potentially power a short gamma-ray burst.
