Materials and Methods: Patients consecutively treated for the replacement of missing posterior teeth were included in the study. Using the implant-abutment interface, which ...

Power Conservative Thevenin-Norton and Norton- Thevenin Transformations

A power conservative Thevenin-Norton and Norton-Thevenin transformations are proposed in this letter. The transformations introduce a voltage and a current generators for which parameters depend on the loading impedance value.

Landauer Defended: Reply to Norton

Ladyman et al (2007) proposed a model of the implementation of logical operations by physical processes in order to clarify the exact statement of Landauer’s Principle, and then offered a new proof of the latter based on the construction of a thermodynamic cycle, arguing that if Landauer’s Principle were false it would be possible to harness a machine that violated it to produce a violation of ...

In Memoriam: Norton Zinder (1929–2012) Geneticist

Z inder, a superb geneticist (who also embraced biochemistry), died on February 3, 2012, following a long illness. He was 83. Zinder came of age at the dawn of microbial genetics. A prodigy with an eidetic memory, he was only 15 when he graduated from the Bronx High School of Science, where he built his first incubator for growing bacteria (a 60-W light bulb in a box with a thermostat).
