A combination of x-ray fluorescence and image processing has been shown to recover text characters written in iron gall ink on parchment, even when obscured by gold paint. Several leaves of the Archimedes Palimpsest were imaged using rapid-scan, x-ray fluorescence imaging performed at the Stanford Synchrotron Radiation Lightsource of the SLAC National Accelerator Laboratory. A simple linear sho...

We describe a new species of the Dendropsophus leucophyllatus Group from the Atlantic Forest of the southern region of State of Bahia, Brazil. It can be distinguished from all species of the D. leucophyllatus Group on the basis of morphological characters (especially its unique dorsal pattern and snout in dorsal view), advertisement calls and divergence in mitochondrial DNA gene sequences. The ...

The author offers some thoughts on reading and teaching Freud, on translating Freud, on translation in general, and on a possible kinship between translation and the psychoanalytic process. His reading of Freud's works, and the years he spent translating them into Hebrew and editing Hebrew editions of his writings, have made a deep and salient impression on his personal psychoanalytic palimpses...

We show that stochastic learning of attractors can take place in a situation in which either only potentiation or only depression of synaptic eecacies are caused in a structured Hebbian way. In each case the transition in the opposite sense take place at random, but occurs only upon presentation of a stimulus. The outcome is an associative memory with the palimpsest property. It is shown that s...

The paper relates technology studies to organization research and examines the technologyas-text metaphor. The study of organization is incomplete as long as tangible technology remains in its blind spot. Linguistic metaphors and analogues, while capturing and indeed amplifying much of received understandings of technology, succeed only partially in repairing the situation. The image of the pal...

The multiple historical layers of Roger Chillingworth's character have been overlooked in criticism of The Scarlet Letter. By considering the possible influence of Robert Browning's dramatic poem Paracelsus (1835) on Hawthorne's romance (1850), as well as the ways in which overtones of both herbalism and clinical medicine complicate Chillingworth's character, one rediscovers Chillingworth as Ha...
