Systolic anterior motion (SAM) of the mitral valve (MV) can be a life-threatening condition. The SAM can result in severe left ventricular outflow tract obstruction and/or mitral regurgitation and is associated with an up to 20% risk of sudden death (which is substantially lower in hypertrophic cardiomyopathy (HCM)). The mechanisms of SAM are complex and depend on the functional status of the v...

Introduction: The performance of software-only video CODECs is often constrained by available processing power. Existing fast motion estimation algorithms are not designed to provide flexible, predictable control of computational complexity. We propose an adaptive algorithm, which maintains the computational complexity of the motion estimation function at various target levels by controlling th...

OBJECTIVES/HYPOTHESIS To review our experience with the diagnosis and treatment of exercise-induced paradoxical vocal fold motion disorder (EPVFMD). STUDY DESIGN Single-institution retrospective review and cohort analysis. METHODS A single-institution retrospective review was performed identifying patients with paradoxical vocal fold motion disorder (PVFMD). Patients with isolated exercise-...

OBJECTIVES To review our experience with the diagnosis and treatment of irritant-induced paradoxical vocal fold motion disorder (IPVFMD). STUDY DESIGN Retrospective chart review. SETTING Tertiary academic referral center. SUBJECTS AND METHODS Thirty-four cases that met IPVFMD criteria and 76 cases of non-IPVFMD were selected from a database of patients with paradoxical vocal fold motion d...

We demonstrate that time-periodic modulation of the nonlinearity coefficient in the discrete nonlinear Schrödinger equation strongly facilitates creation of traveling solitons in the lattice. We predict this possibility in a semi-qualitative form analytically, and test it in direct numerical simulations. Systematic computations reveal several generic dynamical regimes, depending on the amplitud...

Cycle-to-cycle variations in respiratory motion can cause significant geometric and dosimetric errors in the administration of lung cancer radiation therapy. A common limitation of the current strategies for motion management is that they assume a constant, reproducible respiratory cycle. In this work, we investigate the feasibility of using rapid MRI for providing long-term imaging of the thor...

the strong ground motions recorded during the 2002 avaj earthquake have been used to estimates wave attenuation, qβ, and spectral decay parameter, κ, for the avaj region. qβ for shear wave is estimatedas a function of frequency in the range of 0.6- 18 hz. the results show that qβ increases with frequency in theform of qβ=62.7 f 0.9. our estimates are within the estimated range for different par...

Abstract G-Brownian motion has potential applications in uncertainty problems and risk measures, which attracted the attention of many scholars. This study investigates almost sure exponential stability nonlinear stochastic delay hybrid systems driven by motion. Due to non-linearity G-expectation distribution motion, it is difficult this issue. Firstly, existence global unique solution derived ...

This paper describes a fully automatic content-based approach for browsing and retrieval of MPEG-2 compressed video. The first step of the approach is the detection of shot boundaries based on motion vectors available from the compressed video stream. The next step involves the construction of a scene tree from the shots obtained earlier. The scene tree is shown to capture some semantic informa...

There are no codes specific to the Beacon transponders. The implantation of the transponders can be coded using CPT codes, such as 32553, 49411, and 55876, based on the anatomical location. Code C9728 (Placement of interstitial device(s) for radiation therapy/surgery guidance (e.g., fiducial markers, dosimeter), for other than the following sites (any approach): abdomen, pelvis, prostate, retro...
