[Esophagitis secondary to jejuno-esophageal reflux after total gastrectomy and Roux-en-Y loop]

We report a case of esophagitis secondary to jejuno-esophageal reflux after total gastrectomy and 60 cm Roux-en-Y jejunal loop. Both esophagitis and jejuno-esophageal reflux disappeared after lenghtening the Y-loop by 50 cm

PHIFACT-a Boolean preprocessor for multi-level logic synthesis

PHIFACT is a multi-level Boolean optimization program characterized by a controlled time-area trade-off. Its first phase, the Boolean phase, uses Boolean techniques of decomposition and merging to carry out a structural analysis and, in particular, to detect shared circuit parts. Its second phase, the restructuring phase, carries out a systematic exploration of the area-time design space by applying a user controlled sequence of transformations minimizing a parameterized cost function. The obtained results show the feasibility of full Boolean computations and open the way to an important family of new structural analysis techniques.Anglai
