Madrid as a Palimpsest

Immune Cell Identity: Perspective from a Palimpsest.

The immune system in mammals is composed of multiple different immune cell types that migrate through the body and are made continuously throughout life. Lymphocytes and myeloid cells interact with each other and depend upon each other, but each are highly diverse and specialized for different roles. Lymphocytes uniquely require developmentally programmed mutational changes in the genome itself...

Building as Propaganda: a Palimpsest of Faith and Power in the Maghreb

An Enzymatic Palimpsest

According to the Compact Oxford English Dictionary, a palimpsest is “a parchment or other surface on which writing has been applied over earlier writing which has been erased.” Scholars are often able to decipher the earlier writing present on palimpsests by using chemical and imaging techniques. In a new study of a key enzyme that’s involved in the biosynthesis of the guanine nucleotides, inos...

Palimpsest: A layered language for exploratory image processing

Palimpsest is a novel purely-visual language intended to support exploratory live programming. It demonstrates a new paradigm for the visual representation of constraint programming that may be appropriate to future generations of keyboardless and touchscreen devices. The current application domain is that of creative image manipulation, although the paradigm can support a wider range of comput...

A palimpsest memory based on an incremental Bayesian learning rule

Capacity limited memory systems need to gradually forget old information in order to avoid catastrophic forgetting where all stored information is lost. This can be achieved by allowing new information to overwrite old, as in the so-called palimpsest memory. This paper describes a new such learning rule employed in an attractor neural network. The network does not exhibit catastrophic forgettin...
