BACKGROUND It was hypothesized that atrial premature contractions (APCs) originating in the pulmonary veins (PVs) or superior vena cava (SVC) can be localized by evaluating characteristics of the P wave. METHODS AND RESULTS Thirty-eight patients with paroxysmal atrial fibrillation were studied. P wave polarity and morphology of the ECGs during pacing from PVs were analyzed and compared to tho...

* Abstract-Heart state information and neural control expound by parameters is useful to early diagnose heart diseases. The purpose of this article was to investigate the efficiency of parameters that express heart state variation and neural control. We have studied three kinds of parameters: global, local and dynamic with different methods to extract heart concealed physiological and pathologi...

BackgroundDual mobility (DM) total hip arthroplasty (THA) implants have been advocated for patients at risk impingement due to abnormal spinopelvic mobility. Impingement against cobalt-chromium acetabular bearings, however, can result in notching of titanium femoral stems. This study investigated the incidence stem associated with DM and sought identify factors.MethodsA multicenter retrospectiv...

According to federal communication commission (FCC) rules, the 3.1 10.6 GHz band is allocated to the ultra wideband (UWB) applications. Due to the overlap of the currently allocated UWB frequency band with the communication systems such as Wireless Local Area Network (WLAN) bands in the 2.4GHz(2.4–2.484GHz), 5.2GHz (5.15–5.35GHz),and 5.8GHz(5.725–5.825GHz) bands, and the World Interoperability ...

A comprehensive three-dimensional simulation model for non-planar substrate lithography is presented. Matching substrate as well as standing wave effects are examined. The projection printing is simulated using Hopkins' results and the exposure model is solved using spectral element discretizations of the nonlinear wave equation coupled with the rate equation for the photoactive compound concen...

A compact triple band notched ultra-wideband (UWB) monopole antenna is presented in this paper. Split Ring Resonator (SRR) structure exploited various forms like Complementary (CSRR), Pair (SRRP) and CSRR on Electromagnetic Band Gap (EBG) to produce characteristics UWB spectrum. The proposed produces functions with integration of all three types SRR primary antenna. parametric analysis each for...

Downlo and others have established that the developmental Notch receptor signaling pathway is active in breast cell lines, as well as in preinvasive and invasive primary samples. Recently, a role for Notch in regulating rarchy of stem and progenitor cells in both normal and cancer epithelium has been elucidated. Because ing the Notch receptor signaling pathway is a possible future breast cancer...

OBJECTIVE To analyse sports sponsorship by food and alcohol companies by quantifying the proportion of time that the main sponsor's logo was seen during each of three cricket telecasts, the extent of paid advertising during the telecast and the contribution by the main sponsor to this, and to describe the associated ground advertising. METHODS DVD recordings of the three telecasts were analys...
