RESTORE--from deduction to leap of faith.
inhibition of pacemaker output in pacemaker-dependent patients and/or false triggering with tracking to the upper rate limit in patients with reduced left ventricular function may be detrimental. Therefore, we cannot support the approach of Martin and co-workers—that is, to leave the pacemaker sensing function activated. In contrast, we recommend deactivating the sensing function in pacemaker-d...
متن کاملMalformed frogs. Making the leap to humans.
Using Landsat satellite images of vegetation, the researchers were able to classify the different types of crops that had been planted in a three-county area of south central Nebraska. A Landsat satellite sensor detects reflected energy in infrared, red, and green wavelengths. The relative reflected intensity of these wavelengths can be used to identify different types of vegetation. Checking t...
متن کاملThe Grand Leap
Causation, Prediction, and Search by Spirtes, Glymour, and Scheines (SGS) is an ambitious book. SGS claim to have methods for discovering causal relations based only on empirical data, with no need for subjectmatter knowledge. These methods—which combine graph theory, statistics and computer science—are said to allow quick, virtually automated, conversion of association to causation. The algori...
متن کاملOn leap Zagreb indices of graphs
The first and second Zagreb indices of a graph are equal, respectively, to the sum of squares of the vertex degrees, and the sum of the products of the degrees of pairs of adjacent vertices. We now consider analogous graph invariants, based on the second degrees of vertices (number of their second neighbors), called leap Zagreb indices. A number of their basic properties is established.
متن کاملLook before you leap.
The decision to leave a job can be very stressful. Multiple variables must be considered before turning in your notice. The goal of this paper is to help you decide if changing jobs is a smart decision, and, if it is, when to do it.
