1. Introduction This report is the second in a series that deals with various aspects of programming in Icon. The first report [1] dealt with generators. Co-expressions are the topic of this second report for two reasons: (1) they derive their utility from generators, and (2) they seem to present more problems to programmers than other features of Icon. The first two parts of this report treat ...

The demand for multi-user systems for supporting groupwork has increased. In this paper, we present a multi-user system that provides an iconic multi-user interface for supporting groupwork. In this system, various kinds of information used in groupwork are represented as icons. As multiple users share the icons, facilities for coordinating icon operation are necessary. The multi-user interface...

BACKGROUND Fear of falling scales typically have a strong floor effect in active people and use short phrases to state overall context of fear-related activities. We developed the Iconographical Falls Efficacy Scale (Icon-FES), which includes more demanding activities and uses pictures to provide more complete environmental contexts. METHODS Two-hundred and fifty community-dwelling older peop...

We report a new technique for assessing the amount of information extracted from the icon that follows a briefly presented picture. The problem of how to measure such information was formulated in terms of how much physical exposure of a picture an icon is worth. Consider two types of stimulus presentations, each with a base duration of d ms. The first is a d-ms picture followed by an icon, and...

Background Hu and colleagues have identified tissue factor (TF-the primary initiator of coagulation and a modulator of angiogenesis) as a common yet specific biomarker and therapeutic target on a variety of cancer cells and angiogenic tumor vascular endothelial cells [1-3]. He has co-invented a TF-targeting Immuno-Conjugate agent named ICON that consists of factor VII (1-406 aa, the natural lig...

1. Introduction Expressions in Icon [7] are capable of generating sequences of results during the course of their evaluation. For this reason, expressions in Icon are often referred to as generators. The primary control mechanism that exploits generators is goal-directed evaluation [12], which provides control backtracking [8]. This paper describes additional control mechanisms that have been a...

Icon is well-known for its high-level approach to non-numeric programming. To increase the application domain of Icon to include communications and other real-time programming problems, concurrent processing capabilities have been added to an experimental version of Icon called Conicon. The concurrent processing language features added to Icon are natural extensions of the existing language. Th...

Electron tomography (ET) plays an important role in studying in situ cell ultrastructure in three-dimensional space. Due to limited tilt angles, ET reconstruction always suffers from the "missing wedge" problem. With a validation procedure, iterative compressed-sensing optimized NUFFT reconstruction (ICON) demonstrates its power in the restoration of validated missing information for low SNR bi...
