1. T-vector and T-loop morphology analysis of ventricular repolarization in ischemic heart disease
Abstract : Background: Sudden cardiac death (SCD) is responsible for about half of all cardiovascular deaths in the western world. Heterogeneous ventricular repolarization (VR) is a common denominator in the genesis of malignant ventricular arrhythmias responsible for SCD and the presence of coronary artery disease (CAD) is an aggravating factor.

2. Antiarrhythmic and arrhythmic effects of an Ikr-blocking class III agent. A clinical and electrocardiographic study of almokalant
Abstract : The interest in class III drugs has increased over the last decades as being potent antiarrhythmic agents in their mode of action by prolongation of repolarization and with no effect on conduction. Class I antiarrhythmic agents have proven effective in conversion of atrial fibrillation (AF), but may cause serious proarrhythmia. READ MORE

3. 2D hybrid modeling of defects in an ultrasonic inspection situation
Abstract : Advanced methods of nondestructive evaluations (NDE) are widely used for in-service inspection in many industrial applications, e.g. nuclear and aerospace industries. In these applications the components are exposed to different degradation mechanisms (e. READ MORE

4. Cardiac memory studies in two human models
Abstract : Background: Cardiac memory is a form of electrical remodeling of the ventricles, where the T vector follows ("remembers') a previously altered QRS vector. On the electrocardiogram (ECG), it presents as T-wave inversions. READ MORE

5. Compound semiconductor materials and processing technologies for photonic devices and photonics integration
Abstract : The advancement of semiconductor optoelectronics relies extensively on materials and processing technologies of ever-increasing sophistication, such as nanometer-range lithography, epitaxial growth methods with monatomic layer control, and anisotropic etching procedures that allows for the precise sculpturing of device features even in the limit of extreme aspect ratios. However, upcoming application needs puts requirements on optimized designs or device performances, e. READ MORE
