Anomalous surface waves from Lop Nor nuclear explosions: Observations and numerical modeling [PDF]
, 1998 Surface waves from the Chinese test site of Lop Nor are analyzed using long-period and broadband stations located at regional and teleseismic distances and at different azimuths. For most azimuths, strong Love waves between 0.02 and 0.045 Hz are observed

, 2011 Rigorous upper limits on the vertical heat transport in two dimensional Rayleigh-Benard convection between stress-free isothermal boundaries are derived from the Boussinesq approximation of the Navier-Stokes equations. The Nusselt number Nu is bounded in

Prandtl and Rayleigh numbers dependences in Rayleigh-Bénard convection [PDF]
Europhysics Letters (EPL), 2002 Using low-temperature gaseous helium close to the critical point, we investigate the Prandtl-number dependence of the effective heat conductivity (Nusselt number) for a 1/2 aspect ratio Rayleigh-Benard cell. Very weak dependence is observed in the range 0.7 < Pr < 21; 2 × 108 < Ra < 2 × 1010: the absolute value of the average logarithmic slope δ = (∂ln

The 2008 Election: A Preregistered Replication Analysis
Statistics and Public Policy, 2017 We present an increasingly stringent set of replications, a multilevel regression and poststratification analysis of polls from the 2008 U.S. presidential election campaign, focusing on a set of plots showing the estimated Republican vote share for ...

Spectral analysis of boundary layers in Rayleigh-Benard convection
, 2007 A combined experimental and numerical study of the boundary layer in a 4:1 aspect-ratio Rayleigh-B\'{e}nard cell over a four-decade range of Rayleigh numbers has been undertaken aimed at gaining a better insight into the character of the boundary layers.

Simulation of the growth of the 3D Rayleigh-Taylor instability in Supernova Remnants using an expanding reference frame [PDF]
, 2010 Context: The Rayleigh-Taylor instabilities generated by the deceleration of a supernova remnant during the ejecta-dominated phase are known to produce finger-like structures in the matter distribution which modify the geometry of the remnant.

Fault-tolerant and finite-error localization for point emitters within the diffraction limit
, 2016 We implement an estimator for determining the separation between two incoherent point sources. This estimator relies on image inversion interferometry and when used with the appropriate data analytics, it yields an estimate of the separation with finite ...

Proceedings of the American Mathematical Society, 1963 We propose to call O2n(V) the Rayleigh function of order 2n. The Rayleigh functions of odd orders are identically zero. These functions were first used by Euler to determine the three smallest zeros of J0(2 Vz); and Rayleigh, independently, calculated the smallest positive zero of J,(z) with the aid of these functions.
