Every day, the Centers for Disease Control and Pre­ vention (CDC) focuses the world’s attention on issues that deserve to be in the public health spotlight. Visitors to the CDC Web site know that this spotlighting is not only a metaphor but also a prominent physical feature on the agency’s Internet home page. Through its Spot­ light section, the CDC summarizes at a glance the most important thi...

The concept of attention is defined by multiple inconsistent metaphors that scientists use to identify relevant phenomena, frame hypotheses, construct experiments, and interpret data. (1) The Filter metaphor shapes debates about partial vs. complete filtering, early vs. late selection, and information filtering vs. enhancement. (2) The Spotlight metaphor raises the issue of spacevs. object-base...

Nine years ago, Cardiovascular Research (vol. 30(4), enlarged cardiomyocytes. In general, hypertrophy character1995) published a Spotlight Issue on signal transduction summarizing important cellular signaling events in cardiovascular cells. At that time, a main focus of research was centered on intracellular cascades modifying cellular responses in multiple cardiovascular cells, including vascu...

We present Spotlight, an automated user guidance technique for improving quality and efficiency of interactive segmentation tasks. Spotlight augments interactive segmentation algorithms by automatically highlighting areas in need of attention to the user during the interaction phase. We employ a 3D Livewire algorithm as our base segmentation method where the user quickly provides a minimal init...

This paper presents an efficient and precise imaging algorithm for the large bandwidth sliding spotlight synthetic aperture radar (SAR). The existing sub-aperture processing method based on the baseband azimuth scaling (BAS) algorithm cannot cope with the high order phase coupling along the range and azimuth dimensions. This coupling problem causes defocusing along the range and azimuth dimensi...

The automatic annotation of textual content with entities from a knowledge base is a well established field. Applications, such as DBpedia Spotlight and GATE enable to identify and disambiguate entities of text at high levels of accuracy. The output of such systems can be used in many different ways. One way is to show knowledge panels which provide a fact-based summary of an entity and provide...

Many experimental results about spatial attention have been explained by assuming the existence of an attentional "spotlight" which can move from one location in visual space to another. Such an account has been recently challenged by findings which show the influence of nonspatial factors in spatial attention. In particular, the so-called "spotlight failure" effect refers to the influence of t...

This paper addresses the formal verification of distributed systems comprising a dynamically changing and potentially unbounded number of processes. We employ the spotlight principle to obtain a concise finitary abstraction of the system and devise an abstraction refinement strategy guided by the analysis of abstract counterexamples. It turns out that the key problem for spotlight refinement is...

Image formation from squinted sliding spotlight synthetic aperture radar (SAR) is limited by azimuth spectral folding and severe two dimension coupling. This paper presents an Extended Wavenumber Domain Algorithm (WDA) for highly squinted sliding spotlight SAR data processing. This algorithm adopts azimuth deramping approach to overcome the azimuth spectral folding phenomenon. The chirp rate fo...
