Feature extraction is an important component of a pattern recognition system. It performs two tasks: transforming input parameter vector into a feature vector and/or reducing its dimensionality. A well-de3ned feature extraction algorithm makes the classi3cation process more e4ective and e5cient. Two popular methods for feature extraction are linear discriminant analysis (LDA) and principal comp...

We present a new method, called the minimum cross-entropy (MCE) method for approximating the optimal solution of NP-hard combinatorial optimization problems and rare-event probability estimation, which can be viewed as an alternative to the standard cross entropy (CE) method. The MCE method presents a generic adaptive stochastic version of Kullback’s classic MinxEnt method. We discuss its simil...

Myocardial Contrast Echocardiography (MCE) is a recent technique that allows to measure regional perfusion in the cardiac wall. Segmentation of MCE sequences would allow simultaneous evaluation of perfusion and wall motion. This paper deals with the application of partial differential equations (PDE) for tracking the endocardial wall. We use a variational optical flow method which we solve nume...

This review presents a brief outline and novel developments of electrophoretic separation in microfluidic chips. Distinct characteristics of microchip electrophoresis (MCE) are discussed first, in which sample injection plug, joule heat, channel turn, surface adsorption and modification are introduced, and some successful strategies and recognized conclusions are also included. Important achiev...

Streptomyces coelicoloris a non-pathogenic soil saprophytic bacterium and is model organism for antibiotic production. This species contains single copy of nine gene cluster known as the mammalian cell entry (mce) operon. operon was originally characterised in Mycobacterium tuberculosisas an important virulence factor acting invasion survival within macrophages encodes ABC transporter cholester...

Fatsia polycarpa, a plant endemic to Taiwan, is an herbal medicine known for treating several inflammation-related diseases, but its biological function needs scientific support. Thus, the anti-inflammatory effects and mechanisms of the methanolic crude extract (MCE) of F. polycarpa and its feature constituents, that is, brassicasterol (a phytosterol), triterpenoids 3 α -hydroxyolean-11,13(18)-...

OBJECTIVES The aim of this research was to evaluate the potential for myocardial contrast echocardiography (MCE) to provoke microscale bioeffects in a canine model. BACKGROUND Myocardial contrast echocardiography induces bioeffects in rat hearts, but translation of such results to larger animal models is uncertain. METHODS Dogs were anesthetized and prepared for open- (n = 22) or closed- (n...

BACKGROUND Myocardial contrast echocardiography (MCE) allows visualization of radiofrequency (RF) ablation lesions in the left ventricle in an animal model. AIM To test whether MCE allows visualization of RF and cryo ablation lesions in the human right atrium using three-dimensional echocardiography. METHODS 18 patients underwent catheter ablation of a supraventricular tachycardia and were ...
