Simpson, Jamesina J. | Three-dimensional subwavelength confinement of a photonic nanojet using a plasmonic nano-antenna GAP | Using 3-D finite-difference time-domain (FDTD) modeling, a microsphere-generating nanojet and gold nanoantenna gap are optimized to achieve 3-D nanojet confinement to a subwavelength volume of about 0.009 μm3 (wherein the edges of the volume are defined at 1/e2 of the maximum electric-field intensi... | | 2014-01-01 |

Bargteil, Adam Wade | Dynamic sprites | Traditional methods for creating dynamic objects and characters from static drawings involve careful tweaking of animation curves and/or simulation parameters. Sprite sheets offer a more drawing-centric solution, but they do not encode timing information or the logic that determines how objects shou... | | 2014-01-01 |

Ring, Terry Arthur | Growth kinetics of hexagonal sub-micrometric β-tricalcium phosphate particles in ethylene glycol | Recently, uniform, non-agglomerated, hexagonal b-tricalcium phosphate (b-TCP) platelets (diameter 400-1700 nm, h 100-200 nm) were obtained at fairly moderate temperatures (90-170 C) by precipitation in ethylene glycol. Unfortunately, the platelet aspect ratios (diameter/thickness) obtained in the ... | | 2014-01-01 |

Bargteil, Adam Wade | Deformation embedding for point-based elastoplastic simulation | We present a straightforward, easy-to-implement, point-based approach for animating elastoplastic materials. The core idea of our approach is the introduction of embedded space-the least-squares best fit of the material's rest state into three dimensions. Nearest neighbor queries in the embedded spa... | | 2014-01-01 |

Mathews, V. John | Equalization of excursion and current-dependent nonlinearities in loudspeakers | This paper presents a novel equalizer for nonlinear distortions in direct-radiator loudspeakers in a closed cabinet by constructing an exact inverse of an electro-mechanical model of the loudspeaker.

Mathews, V. John | Neural decoding using a nonlinear generative model for brain-computer interface | Kalman filters have been used to decode neural signals and estimate hand kinematics in many studies. However, most prior work assumes a linear system model, an assumption that is almost certainly violated by neural systems. In this paper, we show that adding nonlinearities to the decoding algorithm ... | | 2014-01-01 |

Liu, Feng | Exceptional optoelectronic properties of hydrogenated bilayer silicene | Silicon is arguably the best electronic material, but it is not a good optoelectronic material. By employing first-principles calculations and the cluster-expansion approach, we discover that hydrogenated bilayer silicene (BS) shows promising potential as a new kind of optoelectronic material. Most ... | | 2014-01-01 |

Venkatasubramanian, Suresh | Multiple target tracking with RF sensor networks | RF sensor networks are wireless networks that can localize and track people (or targets) without needing them to carry or wear any electronic device.
