ACUTE MEDIASTINAL WIDENING

Acute Mediastinal Emphysema with Generalized Emphysema

Mediastinal Pseudocyst in Acute on Chronic Pancreatitis.

Pseudocyst is a common complication of Acute and chronic pancreatitis. However, its extension into the mediastinum is a rare entity. We present a case of 52 years male with acute on chronic pancreatitis (alcohol related) who presented with dysphagia and dyspnoea and was found to have a pancreatic pseudocyst extending upto the neck. Ultrasound fails to pick up mediastinal pseudocysts and require...

Generalized Widening

We present a new threat based search algorithm that outperforms other threat based search algorithms and selective knowledge-based for open life and death problem solving in the game of Go. It generalizes the Iterative Widening algorithm which consists in iteratively increasing the threat searched at the root. The main idea of Generalized Widening is to perform Iterative Widening at all max nod...

Widening Sharing

We study the problem of an efficient and precise sharing analysis of (constraint) logic programs. After recognizing that neither plain Sharing nor its non-redundant (but equivalent) abstraction scale well to real programs, we consider the domain proposed by C. Fecht [11, 12]. This domain consists of a combination of Pos with a quite weak abstraction of Sharing. While verifying that this domain ...

Lookahead Widening

We present lookahead widening, a novel technique for using existing widening and narrowing operators to improve the precision of static analysis. This technique is both self-contained and fully-automatic in the sense that it does not rely on separate analyzes or human involvement. We show how to integrate lookahead widening into existing analyzers with minimal effort. Experimental results indic...
