Correspondence e-mail: [email protected] A method for rapidly building -sheets into electron-density maps is presented. -Strands are identified as tubes of high density adjacent to and nearly parallel to other tubes of density. The alignment and direction of each strand are identified from the pattern of high density corresponding to carbonyl and C atoms along the strand averaged over all re...

SUMMARY KEGG pathway database is a collection of manually drawn pathway maps accompanied with KGML format files intended for use in automatic analysis. KGML files, however, do not contain the required information for complete reproduction of all the events indicated in the static image of a pathway map. Several parsers and editors of KEGG pathways exist for processing KGML files. We introduce K...

Remote sensing has more advantages than the traditional methods of land surface water (LSW) mapping because it is a low-cost, reliable information source that is capable of making high-frequency and repeatable observations. The normalized difference water indexes (NDWIs), calculated from various band combinations (green, near-infrared (NIR), or shortwave-infrared (SWIR)), have been successfully...

We prove the existence of a fixed point for a renormalization operator acting on a space of critical Lorenz maps with exponent 2. The proof is computer assisted and is implemented using the language Haskell. All the source code (∼ 200 lines) is included in this document.

Magnetic Resonance Imaging is an established technology for both imaging and functional studies in clinical and research environments. The field is still very research intense. Two major research areas are acquisition time and signal quality. The last decade has provided tools for more efficient possibilities of trading these factors against each other through parallel imaging. In this thesis o...

Global aspects of the motion of passive scalars in time-dependent incompressible fluid flows are well described by volume-preserving (Liouvillian) three-dimensional maps. In this paper the possible invariant structures in Liouvillian maps and the two most interesting nearly-integrable cases are investigated. In addition, the fundamental role of invariant lines in organizing the dynamics of this...

Old maps are increasingly used as a source for historical research. This is a consequence of the increased availability of old maps in digital form, of the emergence of user-friendly Geographical Information Systems, and of a heightened awareness of the unique information stored in old maps. As with every source for historical studies, when old maps are georeferenced and information is extracte...

objectives the aim of this study was to assess soils of khorramabad metropolis in order to establish the concentration of lead and develop a contamination factor map. materials and methods soil samples were collected from 25 different urban parks in khorramabad, iran. the mean pb contents in the urban topsoil samples were compared with mean concentrations for other cities around the world. a sp...

We present the development of a physically-based dust source map for GOCART-AFWA module in WRF-Chem model. The new parameterization is based on MODIS-NDVI and an updated emission strength computed every 15 days from latest satellite observations. Modeling simulations period April–May 2017 over Mediterranean, north Africa, Middle East are compared with observations AOD at 31 AERONET stations. ca...
