In order to define more precisely meaningful points on ventricular and great vessel electrokymograms, intraluminal and intracavitary pressures have been simultaneously recorded. Electrokymograms of the superior vena cava and the pulmonary artery show remarkable constancy of time relationships with simultaneously recorded intraluminal pressure curves. The ventricular electrokymogram is more diff...

Kurtin, Bierman and Yontef (1) reported on the prevention of ultraviolet erythema by iontophoresis of a solution of Pyribenzamine (N -pyridyl-N -benzyl-N -dimethylethylene diamine hydrochloride) into the skin prior to exposure to a hot quartz ultraviolet lamp. They attributed this effect to the "antihistaminic "action of Pyribenzamine in the tissues. We were able to confirm the findings of Kurt...

Ocean Drilling Program Leg 210 was devoted to studying the history of rifting and postrift sedimentation in the Newfoundland–Iberia rift. Drilling was conducted in the Newfoundland Basin along a transect conjugate to previous drilling on the Iberia margin (Legs 149 and 173). This was the first time that deep-sea drilling has been conducted on both sides of a nonvolcanic rift in order to underst...

MPP Haskell is a parallel implementation of the Haskell functional language for the Thinking Machines Inc. CM-5 large-scale distributed-memory multiprocessor. MPP Haskell is a derivative of GUM, a message-based parallel implementation of Haskell. GUM was carefully designed to minimise performance loss from low-bandwidth and high-latency communications; as an apparent consequence MPP Haskell, wi...

The character of the incoming plate subducting at convergent margins and the processes affecting it as it passes below the shallow forearc may play a major role in the nature and extent of hazardous intraplate seismicity as well as the magnitude of volcanism and the chemistry of lavas produced in the overlying volcanic arc. The fate of incoming sediments and ocean crust and of their associated ...

The programming languages of today are stuck in a deep rut that has developed over the past 50 years. Although we are faced with new challenges posed by enormous advances in hardware and internet technology, we continue to struggle with old-fashioned languages based on rigid, static, closed-world file-based views of programming. We argue the need for a new class of dynamic languages that suppor...

A t-proximity detecting (t-PD) code can detect when a received word is at distance t from the transmitted codeword. For non-trivial values of t, a t-proximity detecting code must be unordered. However, not all unordered codes are t-proximity detecting. This report characterizes t-proximity detecting (t-PD) codes, and presents some properties of such codes. Designs of t-PD codes and lower bounds...

We describe a general model for integrating object-oriented features in calculi of mobile agents. We then study two complementary instances of the model based, respectively, on subjective and objective moves: the interest in the resulting calculi is illustrated by means of a number of examples. The work we describe is not nished: this report should be understood as a rst step towards deening a ...
