background: c linical trials of revascularization have routinely under-enrolled elderly subjects. thus, symptom relief and improved survival might not apply to elderly patients, in whom the risk of mortality and disability from revascularization procedures seems to be high and co-morbidity is more prevalent. the present case control study was performed to draw a comparison in terms of the proce...

Much of our commonsense knowledge about the real world is concerned wi th the way things are done. This knowledge is often in the form of procedures or sequences of actions for achieving particular goals. In this paper, a formalism is presented for representing such knowledge based on the notion of process. A declarative semantics for the represen­ tation is given, which allows a user to state ...

M unpleasant, uncomfortable, and painful procedures take place throughout various areas in the hospital, including the emergency department, intensive care units, general medicine floors, and procedural areas. These procedures can include, but are not limited to, cardioversion, orthopedic injury reduction, burn debridement, endoscopy, bronchoscopy, and interventional imaging.1,2 Patients may ex...

In this paper, we propose an automatic method for generating roads based on a weighted anisotropic shortest path algorithm. Given an input scene, we automatically create a path connecting an initial and a final point. The trajectory of the road minimizes a cost function that takes into account the different parameters of the scene including the slope of the terrain, natural obstacles such as ri...

This chapter introduces the computational infrastructure that is used to bridge the gap between results from sensorimotor processing and language. It consists of a system called Incremental Recruitment Language (IRL) that is able to configure a network of cognitive operations to achieve a particular communicative goal. IRL contains mechanisms for finding such networks, chunking subnetworks for ...

We propose a single-valued solution that extends both the consistent Shapley value of Maschler and Owen (1989) and Raiffa’s discrete bargaining solution to a large class of NTU games. Though not axiomatized, the solution is motivated via the Nash program. In this respect, we follow an approach that is similar to the one initiated by Hart and Mas-Collel (1996). JEL Classification: C71. Aspirant ...

We present a simple model for synthesis of butterfly wing patterns. The model simulates the formation of eyespots as are called the rounded circular arrangements which appear in many butterfly species. We illustrate our results with the examples of Diatheria clymena and Automeris io species.

Overhangs have been a major stumbling block in the context of terrain synthesis models. These models resort invariably to a heightfield paradigm, which immediately precludes the existence of any type of overhang. This article presents a new technique for the generation of surfaces, with the ability to model overhangs in a procedural way. This technique can be used generally to model landscape e...

The view of NLs as codes mediating a mapping between “expressions” and the world is abandoned to give way to a view where utterances are seen as actions aimed to locally and incrementally alter the affordances of the context. Such actions employ perceptual stimuli composed not only of “words” and “syntax” but also elements like visual marks, gestures, sounds, etc. Any such stimuli can participa...

BACKGROUND Emergency physicians often treat patients who require procedural sedation for the management of upper extremity fractures, dislocations, and abscesses (upper extremity emergencies). Unfortunately, procedural sedation is associated with several rare but potentially serious adverse effects and requires continuous hemodynamic monitoring and several dedicated staff members. The purpose o...
