Symmetric polynomials in information theory: entropy and subentropy
(AIP PublishingJournal of Mathematical Physics, 2015-06-12)
Entropy and other fundamental quantities of information theory are customarily
expressed and manipulated as functions of probabilities. Here we study the entropy H
and subentropy Q as functions of the elementary symmetric ...
Anatomy of the ATLAS diboson anomaly
(2015-08-19)
We perform a general analysis of new physics interpretations of the recent ATLAS diboson excesses over Standard Model expectations in LHC Run I collisions. Firstly, we estimate a likelihood function in terms of the truth ...
Singular Inflation
(APSPhysical Review D, 2015-04-08)
We prove that a homogeneous and isotropic universe containing a scalar field with a power-law potential, V(ϕ)=Aϕ^n, with 0<n<1 and A>0 always develops a finite-time singularity at which the Hubble rate and its first ...
New Singularities in Unexpected Places
(World ScientificInternational Journal of Modern Physics D, 2015-09-28)
Spacetime singularities have been discovered which are physically much weaker than those predicted by the classical singularity theorems. Geodesics evolve through them and they only display infinities in the derivatives ...
Geniculo-Cortical Projection Diversity Revealed within the Mouse Visual Thalamus
(PLOSPLOS ONE, 2016-01-04)
The mouse dorsal lateral geniculate nucleus (dLGN) is an intermediary between retina and primary visual cortex (V1). Recent investigations are beginning to reveal regional complexity in mouse dLGN. Using local injections ...
Convective mass transfer from a submerged drop in a thin falling film
(Cambridge University PressJournal of Fluid Mechanics, 2016-01-25)
We study the fluid mechanics of removing a passive tracer contained in small, viscous drops attached to a flat inclined substrate using thin gravity-driven film flows. A convective mass transfer establishes across the ...
Periodization, translation, prescription and the emergence of Classical French
(WileyTransactions of the Philological Society, 2016-03-17)
In this article we demonstrate how fine-grained analysis of salient features of linguistic change over a relatively short, but significant period can help refine our notions of periodization. As our case study, we consider ...
Twistors and the massive spinning particle
(IOP ScienceJournal of Physics A: Mathematical and Theoretical, 2015-12-07)
Gauge-invariant twistor variables are found for the massive spinning particle with N-extended local worldline supersymmetry, in spacetime dimensions D = 3, 4, 6. The twistor action is manifestly Lorentz invariant but the ...
The synthesis of di-carboxylate esters using continuous flow vortex fluidics
(Royal Society of ChemistryGreen Chemistry, 2015-12-01)
A vortex fluidic device (VFD) is effective in mediating the synthesis of di-esters at room temperature. Processing under ambient conditions allows for a simple and efficient synthesis, whilst operating under continuous ...
Motility of Colonial Choanoflagellates and the Statistics of Aggregate Random Walkers
(American Physical SocietyPhysical Review Letters, 2016-01-22)
We illuminate the nature of the three-dimensional random walks of microorganisms composed of individual organisms adhered together. Such aggregate random walkers are typified by choanoflagellates, eukaryotes that are the ...
