Accurate 3D Rigid-Body Target Motion and Structure Estimation by Using GMTI/HRR with Template Information
A framework of simultaneously estimating the motion and structure parameters of a 3D object by using high range resolution (HRR) and ground moving target indicator (GMTI) measurements with template information is given.

Spoken language understanding—interpreting the signs given by a speech signal
Spoken language understanding (SLU) is the interpretation of signs conveyed by a speech signal. SLU and natural language understanding (NLU) share the goal of obtaining a conceptual representation of natural language sentences. Specific to SLU is the fact that signs to be used for interpretation are coded into signals along with other information such as…

Defect Reduction of GaAs/Si Epitaxy By Aspect Ratio Trapping
We report on the metallorganic chemical vapor deposition growth of GaAs on patterned Si (001) substrates, which utilizes the aspect ratio trapping method. It was found that when growingGaAs above the SiO2SiO2 trenched region, coalescence-induced threading dislocations and stacking faults originated…

Electroadhesive Robots – Wall Climbing Robots Enabled By a Novel, Robust, and Electrically Controllable Adhesion Technology
This paper describes a novel clamping technology called compliant electroadhesion, as well as the first application of this technology to wall climbing robots. As the name implies, electroadhesion is an electrically controllable adhesion technology.

Microscopic Theory of Electron Spin Relaxation in N@ C60
Here, we present a microscopic theory of electron spin relaxation in N@C60. The theory combines (1) the spin-orbit interaction of N 2p electrons, which mixes the ground-state 4S with excited 2P and 2D states.

Thick Protective UHTC Coatings for SiC-Based Structures: Process Establishment
A new process to form thick and dense ultra-high-temperature ceramic (UHTC) composite coatings over SiC surfaces is described. Coatings of ZrB2/SiC/(ZrC) thicker than 100 μm are formed by a reaction-bonded SiC (RBSC) approach based on Si infiltration into ZrB2/C preform coating.

Effect of Sleep Stage on Breathing in Children with Central Hypoventilation
Given the differences in anatomy, physiology, and REM sleep distribution between infants and older children, and the reduced number of limb movements during REM sleep, we hypothesized that older subjects with CHS would have more severe hypoventilation during REM than NREM sleep.

Modeling and Verification of Time-Triggered Communication Protocols
We present the basis of the modeling method and discuss two related verification approaches for analyzing complex, real-time distributed systems.

Applicability of Information Theory to the Quantification of Responses to Anthropogenic Noise By Southeast Alaskan Humpback Whales
We assess the effectiveness of applying information theory to the characterization and quantification of the affects of anthropogenic vessel noise on humpback whale (Megaptera novaeangliae) vocal behavior in and around Glacier Bay, Alaska.

Origami embedding of piecewise-linear two-manifolds
Answering a question of Erik Demaine, we prove that the surface of any bounded polyhedron in Euclidean 3-space can be folded flat.
