The Physics of Eccentric Binary Black Hole Mergers. A Numerical Relativity Perspective | Gravitational wave observations of eccentric binary black hole mergers will
provide unequivocal evidence for the formation of these systems through

observations, consistent with ... | 1 | 0 | 0 | 0 | 0 | 0 |
Joint Computation and Communication Cooperation for Mobile Edge Computing | This paper proposes a novel joint computation and communication cooperation
approach in mobile edge computing (MEC) systems, which enables user cooperation

Propagating wave correlations in complex systems | We describe a novel approach for computing wave correlation functions inside

Cost-Effective Cache Deployment in Mobile Heterogeneous Networks | This paper investigates one of the fundamental issues in cache-enabled
heterogeneous networks (HetNets): how many cache instances should be deployed
at different base stations, in order to provide guaranteed service in a

hierarchical caching, wher... | 1 | 0 | 0 | 0 | 0 | 0 |
Experimental demonstration of a Josephson magnetic memory cell with a programmable π-junction | We experimentally demonstrate the operation of a Josephson magnetic random

On the Dynamics of Supermassive Black Holes in Gas-Rich, Star-Forming Galaxies: the Case for Nuclear Star Cluster Coevolution | We introduce a new model for the formation and evolution of supermassive

A Concave Optimization Algorithm for Matching Partially Overlapping Point Sets | Point matching refers to the process of finding spatial transformation and

mixed linear as... | 1 | 0 | 0 | 0 | 0 | 0 |
Adaptive Mesh Refinement in Analog Mesh Computers | The call for efficient computer architectures has introduced a variety of

On the local view of atmospheric available potential energy | The possibility of constructing Lorenz's concept of available potential
energy (APE) from a local principle has been known for some time, but has

which like kinetic... | 0 | 1 | 0 | 0 | 0 | 0 |
GdRh$_2$Si$_2$: An exemplary tetragonal system for antiferromagnetic order with weak in-plane anisotropy | The anisotropy of magnetic properties commonly is introduced in textbooks

theory. In cont... | 0 | 1 | 0 | 0 | 0 | 0 |
A Kullback-Leibler Divergence-based Distributionally Robust Optimization Model for Heat Pump Day-ahead Operational Schedule in Distribution Networks | For its high coefficient of performance and zero local emissions, the heat

integration of HPs may aggravate the daily peak-valley gap in distribution
networks significantly.

Towards Optimally Decentralized Multi-Robot Collision Avoidance via Deep Reinforcement Learning | Developing a safe and efficient collision avoidance policy for multiple

Metropolis-Hastings Algorithms for Estimating Betweenness Centrality in Large Networks | Betweenness centrality is an important index widely used in different domains

computationally expensive to compute exact betweenness scores. Therefore in

Learning Flexible and Reusable Locomotion Primitives for a Microrobot | The design of gaits for robot locomotion can be a daunting process which

Sensitivity analysis using perturbed-law based indices for quantiles and application to an industrial case | In this paper, we present perturbed law-based sensitivity indices and how to

The Robustness of LWPP and WPP, with an Application to Graph Reconstruction | We show that the counting class LWPP [FFK94] remains unchanged even if one

a superpolynomial number of gap values by relativizable proof techniques.

Time- and spatially-resolved magnetization dynamics driven by spin-orbit torques | Current-induced spin-orbit torques (SOTs) represent one of the most effective

Quenching of supermassive black hole growth around the apparent maximum mass | Recent quasar surveys have revealed that supermassive black holes (SMBHs)
rarely exceed a mass of $M_{\rm BH} \sim {\rm a~few}\times10^{10}~M_{\odot}$
during the entire cosmic history. It has been argued that quenching of the BH
growth is caused by a transition of a nuclear accretion disk into an advection
