1 A Cellular Architecture for Ray Tracing
We propose in this paper a massively parallel machine dedicated to image synthesis by discrete ray tracing techniques. This machine is a four-stage pipeline, the last stage being a bidimensional cellular array with one cell per pixel. Two main phases describe its behaviour: • Loading into the cellular array of the objects of the scene to be displayed, after having been transformed into sets of ...
متن کاملComparative lineage tracing reveals cellular preferences for prostate cancer initiation
The interplay of different cell types of origin and distinct oncogenic mutations may determine the tumor subtype. We have recently found that although both basal and luminal epithelial cells can initiate prostate tumorigenesis, the latter are more likely to undergo transformation in response to a range of oncogenic events.
متن کاملSortase-mediated labelling of lipid nanodiscs for cellular tracing.
Lipid nanodiscs have broad applications in membrane protein assays, biotechnology and materials science. Chemical modification of the nanodiscs to expand their functional attributes is generally desirable for all of these uses. We present a method for site-selective labelling of the N-terminus of the nanodisc's membrane scaffold protein (MSP) using the Sortase A protein. Labelling of the MSP wa...
متن کاملTracing cellular and molecular mechanisms involved in endometriosis.
The aetiology and pathogenesis of endometriosis, defined as the presence of endometrium-like tissue outside the uterine cavity, is largely unknown. In this paper we present and discuss possibilities to study the putative pathogenic properties of endometriotic cells in vitro. The current focus of our investigations is on the invasive phenotype of the disease, assuming that this might contribute ...
متن کاملOn descent for coalgebras and type transformations
We find a criterion for a morphism of coalgebras over a Barr-exact category to be effective descent and determine (effective) descent morphisms for coalgebras over toposes in some cases. Also, we study some exactness properties of endofunctors of arbitrary categories in connection with natural transformations between them as well as those of functors that these transformations induce between co...
