we describe a rare case of laryngeal fasciitis ossificans. a 58-year-old man presented with hoarseness and a nodule was found in the larynx. excisional biopsy was performed, and follow-up laryngoscopy showed complete resolution of this reactive lesion, and normal laryngeal function. the 0.6 cm diameter nodule was well circumscribed and histologically, the lesion was composed of uniform woven bo...

Fusion frame theory is an emerging mathematical theory that provides a natural framework for performing hierarchical data processing. A fusion frame can be regarded as a frame-like collection of subspaces in a Hilbert Communicated by Qiyu Sun. P.G.C. and A.H. were supported by NSF DMS 0704216.

An online approach is proposed for Video registration of dynamic scenes, such as scenes with dynamic textures, moving objects, motion parallax, etc. This approach has three steps: (i) Assume that a few frames are already registered. (ii) Using the registered frames, the next frame is predicted. (iii) A new video frame is registered to the predicted frame. Frame prediction overcomes the bias int...

The primary datum of a scattering experiment is the differential cross section. It is defined as the number of particles (events) per second per solid angle observed by the detector divided by the number of particles per unit area per second incident per target particle (scattering center). 1 In many scattering experiments the detector is most conveniently described using the fixed reference fr...

We present a distributed system that provides low-cost, interactive response for three-dimensional graphics applications. The system runs on commonly available hardware, which consists of a set of distributed workstations connected by a mediumbandwidth network. Problems such as heterogeneous processors, time-shared use of the workstations, and non-uniform image complexity are addressed through ...

The JVT-G012 rate control algorithm for H.264 video encoding can get high encoding efficiency. But the algorithm has disadvantage that the target bit allocation in the frame layer is uniform according to the buffer residual bits. This paper presents a new method which uses a content complexity quotiety of frame for allocating target bits in the frame layer more accurately. The content complexit...

We investigate the inside structure of one-dimensional reaction-diffusion traveling fronts. The reaction terms are of the monostable, bistable or ignition types. Assuming that the fronts are made of several components with identical diffusion and growth rates, we analyze the spreading properties of each component. In the monostable case, the fronts are classified as pulled or pushed ones, depen...

We present SECONDO, a new generic environment supporting the implementation of database systems for a wide range of data models and query languages. On the one hand, this framework is more flexible than common extensible and object-relational systems, offering the full extensibility of second-order signature, the formal basis for data and query language definitions in SECONDO. On the other hand...

In the context of false vacuum decay at zero temperature, it is well known that bubbles expand with uniform proper acceleration. We show this uniformly accelerating expansion suffers from an instability related to bubble size. This can be observed in Minkowski spacetime as a tachyonic mode spectrum fluctuations for energy functional reference frame which wall appears static. such frame, arbitra...
