Microscale flow dynamics of ribbons and sheets
(Royal Society of ChemistrySoft Matter, 2017-01-18)
Numerical study of the hydrodynamics of thin sheets and ribbons presents difficulties associated with resolving multiple length scales. To circumvent these difficulties, asymptotic methods have been developed to describe ...
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 ...
Coherent structures in interacting vortex rings
(American Physical SocietyPhysical Review Fluids, 2017-02-21)
We investigate experimentally the nonlinear structures that develop from interacting vortex rings induced by a sinusoidally oscillating ellipsoidal disk in fluid at rest. We vary the scaled amplitude or Keulegan-Carpenter ...
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 ...
Autophoretic flow on a torus
(American Physical SocietyPhysical Review Fluids, 2017-03-02)
Phoretic swimmers provide new avenues to study nonequilibrium statistical physics and are also hailed as a promising technology for bioengineering at the cellular scale. Exact solutions for the locomotion of such swimmers ...
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 ...
Dynamical α-cluster model of $^{16}$O
(American Physical SocietyPhysical Review C, 2017-03-09)
We calculate the low-lying spectrum of the $^{16}$O nucleus using an α-cluster model which includes the important tetrahedral and square configurations. Our approach is motivated by the dynamics of α-particle scattering ...
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 ...
