Helical Tubes in Crowded Environments
Yehuda Snir, Randall D. Kamien
When placed in a crowded environment, a semi-flexible tube is forced to fold so as to make a more compact shape. One compact shape that often arises in nature is the tight helix, e…
Geometry of proteins: hydrogen bonding, sterics and marginally compact tubes
Jayanth R. Banavar, Marek Cieplak, Alessandro Flammini +8
The functionality of proteins is related to their structure in the native state. Protein structures are made up of emergent building blocks of helices and almost planar sheets. A s…
Entropically Driven Helix Formation
Yehuda Snir, Randall D. Kamien
The helix is a ubiquitous motif for biopolymers. We propose a heuristic, entropically based model that predicts helix formation in a system of hard spheres and semiflexible tubes.…
The Sloan Digital Sky Survey Quasar Catalog I. Early Data Release
Donald P. Schneider, Gordon T. Richards, Xiaohui Fan +9
We present the first edition of the Sloan Digital Sky Survey (SDSS) Quasar Catalog. The catalog consists of the 3814 objects (3000 discovered by the SDSS) in the initial SDSS publi…
Colors of 2625 Quasars at 0<z<5 Measured in the Sloan Digital Sky Survey Photometric System
Gordon T. Richards, Xiaohui Fan, Donald P. Schneider +3
We present an empirical investigation of the colors of quasars in the Sloan Digital Sky Survey (SDSS) photometric system. The sample studied includes 2625 quasars with SDSS photome…
The Luminosity Function of Galaxies in SDSS Commissioning Data
SDSS Collaboration, M. R. Blanton
During commissioning observations, the Sloan Digital Sky Survey (SDSS) has produced one of the largest existing galaxy redshift samples selected from CCD images. Using 11,275 galax…
