Memex is a high-performance computing (HPC) cluster administered by Carnegie Science. Since 2015, Carnegie Science has provided computational resources to all of its research scientists to aid in solving their most challenging and data-intensive calculations.
3D reconstruction of an Arabidopsis root expressing a marker for the cell membrane (cyan) and a marker for the signal transduction protein Bzr1 (magenta). When Bzr1 is activated as a result of upstream steroid hormone perception, it translocates into the cell nucleus, where it acts as part of a central signal processing module to integrate perception of other signals that regulate growth, including light. Quantifying the movement of Bzr1 from the cytosol to the nucleus allows for dynamic visualization of steroid signaling on the level of individual cells. The spheres show nuclei that are identified by image analysis.
Removal of gas from a galaxy disk as that galaxy falls into a large galaxy cluster (via the process of ram pressure stripping). Movie credit: Stephanie Tonnesen (Alvin E. Nashman Postdoctoral Fellow; OBS), made using the yt of Turk et al. 2011).
Observatory researchers have developed models which describe the formation and evolution of galaxies in the Universe. One application of these models is to construct virtual universes by running on top of the latest generation of cosmological N-body simulations of dark matter. Such virtual universes (an example of which is shown at right) will be used to directly compare to the results of forthcoming galaxy surveys (e.g. LSST, DES, etc.).
We seek to expand the capabilities existing computational methods for all computational platforms, as well as interface with new codes that allow the multidimensional visualization of the numerical data. This movie shows the evolution over 4 billion years of Earth history, with the Earth becoming overall lighter in color with age. The 2D simulation of convection in Earth’s interior, with the core at the center (not modeled). Movie: Erik Hauri, DTM
The memex (a portmanteau of "memory" and "index") is the name of the hypothetical proto-hypertext system that Vannevar Bush described in his 1945 The Atlantic Monthly article "As We May Think". Bush envisioned the memex as a device in which individuals would compress and store all of their books, records, and communications, "mechanized so that it may be consulted with exceeding speed and flexibility." The memex would provide an "enlarged intimate supplement to one's memory". The concept of the memex influenced the development of early hypertext systems (eventually leading to the creation of the World Wide Web) and personal knowledge base software. The hypothetical implementation depicted by Bush for the purpose of concrete illustration was based upon a document bookmark list of static microfilm pages, and lacked a true hypertext system where parts of pages would have internal structure beyond the common textual format. Early electronic hypertext systems were thus inspired by memex rather than modeled directly upon it...
