Background & Aims: The clinical value of T wave inversion (TWI) in the lead aVL in diagnosing coronary artery disease (CAD) remains unclear. Hence, we aim to evaluate the association between TWI in the aVL lead and the severity and location of coronary artery stenosis in elective coronary angiography. Material and Method: Electrocardiograms (ECGs) of 167 consecutive patients undergoing electiv...

The clinical-immunological spectrum of human Leishmania (L.) infantum chagasi-infections in the Brazilian Amazon has been defined using DTH/IFAT-IgG immune assays and clinical statuses infected individuals, revealing five profiles: three asymptomatic [Asymptomatic Infection (AI), Subclinical Resistant (SRI), Indeterminate Initial (III)], two symptomatic profiles [Subclinical Oligosymptomatic (S...

INTRODUCTION: The present note discusses some evidence on the increasing potential risk for American visceral leishmaniasis (AVL) transmission in the Northern Brazilian State of Amapá, the Guianan-Amazon biome. METHODS Early and present data about AVL were collected, including our recent entomological findings. RESULTS: The spread of the sand fly vector Lutzomyia longipalpis, and a sylvati...

We prove that any AVL tree admits a linear-area straight-line strictly-upward planar grid drawing, that is, a drawing in which (a) each edge is mapped into a single straight-line segment, (b) each node is placed below its parent, (c) no two edges intersect, and (d) each node is mapped into a point with integer coordinates. © 1998 Elsevier Science B.V.

An AVL tree [1] is the original type of balanced binary search tree. An insertion in an n-node AVL tree takes at most two rotations, but a deletion in an n-node AVL tree can take Θ(log n). A natural question is whether deletions can take many rotations not only in the worst case but in the amortized case as well. A sequence of n successive deletions in an n-node tree takes O(n) rotations [3], b...

AVL has been used extensively in public transit, law enforcement, and EMS applications (among others), and is garnering more and more interest with the highway maintenance community. Sponsored by the Kansas DOT, The University of Kansas conducted a study of the use of AVL for highway maintenance activities, especially snow removal. State DOTs and other transportation agencies were surveyed with...

Automated Vehicle Location (AVL) based Transport Monitoring System has created some interest to many researchers. Currently, the implementation of AVL based Transport Monitoring System rely on the Global Positioning System (GPS) data, which can produce real time location of a vehicle. Implementation of a complete Transport Monitoring System requires other components such as communication module...

AVL encompasses a variety of location and communication technologies. Archived AVL (or on-vehicle data recording) uses an onboard computer to record and store bus operation data and upload them to a data tank at a specific time (usually daily); real-time AVL (or offvehicle data recording) sends bus travel and operation data to a central computer in real time (usually at a frequency of 30 s to 5...
