Non-monotonic temperature evolution of dynamic correlations in glass-forming liquids
, 2011 The viscosity of glass-forming liquids increases by many orders of magnitude if their temperature is lowered by a mere factor of 2-3 [1,2]. Recent studies suggest that this widespread phenomenon is accompanied by spatially heterogeneous dynamics [3,4 ...

Subquadratic harmonic functions on Calabi-Yau manifolds with Euclidean volume growth
, 2019 We prove that on a complete Calabi-Yau manifold $M$ with Euclidean volume growth, a harmonic function with subquadratic polynomial growth is the real part of a holomorphic function. This generalizes a result of Conlon-Hein.

Gating Input to Visual Cortex by Feedback to LGN [PDF]
, 1998 Anatomical studies have documented massive back-projections from higher to lower visual cortices and to the lateral geniculate nucleus (LGN). The large number of synapses from these sources suggest that they should have a profound influence on the ...

Back-reaction of perturbation wave packets on gray solitons
, 2012 Within the Bogoliubov-de Gennes linearization theory of quantum or classical perturbations around a background solution to the one-dimensional nonlinear Schr\"odinger equation, we study the back-reaction of wave packet perturbations on a gray soliton ...

Coalescence of Two Impurities in a Trapped One-dimensional Bose Gas
, 2018 We study the ground state of a one-dimensional (1D) trapped Bose gas with two mobile impurity particles. To investigate this set-up, we develop a variational procedure in which the coordinates of the impurity particles are slow-like variables.

Advanced turboprop noise prediction: Development of a code at NASA Langley based on recent theoretical results [PDF]
The development of a high speed propeller noise prediction code at Langley Research Center is described. The code utilizes two recent acoustic formulations in the time domain for subsonic and supersonic sources. The structure and capabilities of the code

Structure of solutions of the Skyrme model on three-sphere. Numerical results
, 2002 The hedgehog Skyrme model on three-sphere admits very rich spectrum of solitonic solutions which can be encompassed by a strikingly simple scheme. The main result of this paper is the statement of the tripartite structure of solutions of the model and ...

Sound propagation elements in evaluation of en route noise of advanced turbofan aircraft [PDF]
Cruise noise from an advanced turboprop aircraft is reviewed on the basis of available wind tunnel data to estimate the aircraft noise signature at the source. Available analytical models are used to evaluate the sound levels at the ground.
