Can phoretic particles swim in two dimensions?
(American Physical SocietyPhysical Review E, 2016-12-16)
Artificial phoretic particles swim using self-generated gradients in chemical species (self-diffusiophoresis) or charges and currents (self-electrophoresis). These particles can be used to study the physics of collective ...
Classification and Reconstruction of High-Dimensional Signals from Low-Dimensional Features in the Presence of Side Information
(IEEEIEEE Transactions on Information Theory, 2016-09-07)
This paper offers a characterization of fundamental limits on the classification and reconstruction of high-dimensional signals from low-dimensional features, in the presence of side information. We consider a scenario ...
Media Query Processing for the Internet-of-Things: Coupling of Device Energy Consumption and Cloud Infrastructure Billing
(IEEEIEEE Transactions on Multimedia, 2016-12-01)
Audio/visual recognition and retrieval applications have recently garnered significant attention within Internet-of-Things (IoT) oriented services, given that video cameras and audio processing chipsets are now ubiquitous ...
Questioning the Mpemba effect: hot water does not cool more quickly than cold
(Nature Publishing GroupScientific Reports, 2016-11-24)
The Mpemba effect is the name given to the assertion that it is quicker to cool water to a given temperature when the initial temperature is higher. This assertion seems counter-intuitive and yet references to the effect ...
Towards radiative transitions in charmonium
(Proceedings of Science, 2016-01-01)
We present preliminary calculations towards radiative transitions in charmonium using anisotropic $\textit{Nf}$=2+1 dynamical ensembles generated by the Hadron Spectrum Collaboration. With the use of newer technologies we ...
Localization and broadband follow-up of the gravitational-wave transient GW150914
(IOP PublishingAstrophysical Journal Letters, 2016-07-20)
A gravitational-wave (GW) transient was identified in data recorded by the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors on 2015 September 14. The event, initially designated G184098 and ...
Bounds on the Number of Measurements for Reliable Compressive Classification
(IEEEIEEE Transactions on Signal Processing, 2016-11-15)
This paper studies the classification of high-dimensional Gaussian signals from low-dimensional noisy, linear measurements. In particular, it provides upper bounds (sufficient conditions) on the number of measurements ...
Mixing efficiency in run-down gravity currents
(Cambridge University PressJournal of Fluid Mechanics, 2016-12-25)
This paper presents measurements of mixing efficiency of the two counter-flowing gravity currents created by symmetric lock exchange in a channel. The novel feature of this work is that the buoyancy Reynolds number of the ...
Two–dimensional viscoplastic dambreaks
(Journal of Non-Newtonian Fluid Mechanics, 2016-12-01)
We report the results of computations for two–dimensional dambreaks of viscoplastic fluid, focusing on the phenomenology of the collapse, the mode of initial failure, and the final shape of the slump. The volume-of-fluid ...
The Modular Aerial Sensing System
(American Meteorological SocietyJournal of Atmospheric and Oceanic Technology, 2016-06-01)
Satellite remote sensing has enabled remarkable progress in the ocean, earth, atmospheric, and environmental sciences through its ability to provide global coverage with ever-increasing spatial resolution. While exceptions ...
