An historical review is given of American visceral leishmaniasis (AVL), with particular reference to the eco-epidemiology of the disease in Brazil. Following the first records of AVL in this country, in 1934, the sandfly Lutzomyia longipalpis (Lutz and Neiva, 1912) was incriminated as the principal vector. It is now generally accepted, however, that there exist a number of cryptic species under...
BACKGROUND Definitive diagnosis of bilateral bundle-branch delay/block may be made when catheter-induced right bundle-branch block (RBBB) develops in patients with baseline left bundle-branch (LBB) block. We hypothesized that a RBBB pattern with absent S waves in leads I and aVL will identify bilateral bundle-branch delay/block. METHODS AND RESULTS Fifty patients developing transient RBBB pat...
Acute myocardial infarction with ST elevation in lead aVL may represent involvement of the first diagonal or the first obtuse marginal branch. This study assesses the correlation among different electrocardiographic patterns of acute myocardial infarction with ST elevation in aVL and the site of the infarct-related artery occlusion. Patients who underwent coronary angiography within 14 days of ...
Precise modeling of radio propagation is necessary for experiencing the benefits of wireless technology for indoor environments. Among many modeling techniques, the ray tracing based prediction models become popular for indoor wireless radio propagation characterization. Though the ray tracing models are popular, their key deficiency is the slower performance. In this paper, an accelerated tech...
This thesis investigates the potential uses of information technologies for transit applications; specifically to the real-time functions of operations monitoring and control and passenger information. To an agency that is currently considering technology to improve performance, this thesis guides the agency through the many issues that should be addressed. The research first investigated the i...
Our study demonstrates that ST-segment elevation in both leads I and aVL noted on admission for an anterior acute myocardial infarction does portend a worse short-term survival. Independent predictors of short-term prognosis in an anterior acute myocardial infarction include ST elevation in both leads I and aVL, advanced age, female gender, left ventricular failure, and malignant arrhythmias.
BACKGROUND The electrocardiogram (ECG) is the most important diagnostic tool for acute myocardial infarction (AMI). T wave inversion (TWI) in lead aVL has not been emphasized or well recognized. OBJECTIVE This study examined the relationship between the presence of TWI before the event and mid-segment left anterior descending (MLAD) artery lesion in patients with AMI. METHODS Retrospective ...
K-Dimensional Height Balanced Trees represent one solution to handle simultaneous tree operations (insertion, search) with multiple value keys in an efficient way. The current paper focuses on discussing some of the intricacies and overhead caused by the concurrency aspects, as well as providing an implementation of the algorithm, together with a discussion regarding its correctness. 1. Context...
