Observational constraints on new exact inflationary scalar-field solutions
(American Physical SocietyPhysical Review D, 2016-10-15)
An algorithm is used to generate new solutions of the scalar-field equations in homogeneous and isotropic universes. Solutions can be found for pure scalar fields with various potentials in the absence and presence of ...
Excited and exotic charmonium, $\textit{D}$$_{s}$ and $\textit{D}$ meson spectra for two light quark masses from lattice QCD
(SpringerJournal of High Energy Physics, 2016-12-19)
We present highly-excited charmonium, $\textit{D}$$_{s}$ and $\textit{D}$ meson spectra from dynamical lattice QCD calculations with light quarks corresponding to $\textit{M}$$_{π}$ ∼ 240 MeV and compare these to previous ...
Worldline CPT and massless supermultiplets
(World Scientific PublishingInternational Journal of Modern Physics A, 2016-09-30)
The action for a massless particle in 4D Minkowski space–time has a worldline-time reversing symmetry corresponding to CPT invariance of the quantum theory. The analogous symmetry of the $\mathscr{N}$-extended superparticle ...
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 ...
