This paper presents a research on arithmetic units targeted to implement model predictive control (MPC) in a custom embedded processor. A novel hardware implementation of cotransformation for the calculation of addition and subtraction in the Logarithmic Number System (LNS) is proposed. This architecture provides a small ROM-less adder/subtracter, with(More)
BACKGROUND & AIMS An extrahepatic human neutrophil collagenase complementary DNA (matrix metalloprotease-8) cloned in an adenovirus vector was used as a therapeutic agent in cirrhosis. METHODS A high titer of clinical-grade AdMMP8 was obtained. RESULTS HeLa cells transduced with AdMMP8 expressed recombinant matrix metalloprotease-8 messenger RNA and(More)
This paper introduces the Interval Logarithmic Number System (ILNS), in which the Logarithmic Number System (LNS) is used as the underlying number system for interval arithmetic. The basic operations in ILNS are introduced and an efficient method for performing ILNS addition and subtraction is presented. The paper compares ILNS to Interval Floating Point(More)
In recent years governments have shown themselves willing to impose blackouts to shut off key communication infrastructure during times of civil strife, and to surveil citizen communications whenever possible. However, it is exactly during such strife that citizens need reliable and anonymous communications the most. In this paper, we present Rangzen, a(More)
Background/Aims: Our group has been involved in searching for different strategies to ameliorate hepatic cirrhosis. The aim of this study was to evaluate the effect of Pirfenidone in the reversion or prevention of cirrhosis experimentally induced in rats by chronic administration of CCl 4 and bile-duct ligation (BDL). Methods: Male cirrhotic Wistar rats (8(More)
