Autor: Gwyneth W. Gordon, Emily E. Schach, Luis Manuel González La Rosa, Aleksa K. Alaica, Allisen C. Dahlstedt, Beth K. Scaffidi, Sara J. Marsteller, Tiffiny A. Tung, Kelly J. Knudson

Publikováno v: Frontiers in Ecology and Evolution, Vol 8 (2020)

The analysis of 87Sr/86Sr has become a robust tool for identifying non-local individuals at archaeological sites. The 87Sr/86Sr in human bioapatite reflects the geological signature of food and water consumed during tissue development. Modeling relat

Stable oxygen and radiogenic strontium variability in the Osmore Drainage, Peru: Implications for intra-regional Andean paleomobility studies

Autor: Sarah I. Baitzel, Allisen C. Dahlstedt, Kelly J. Knudson, Emily E. Schach

Publikováno v: Journal of Archaeological Science: Reports. 37:102933

The Osmore Drainage of southern Peru has a long and rich history of human occupation. While the utility of stable oxygen and radiogenic strontium isotope values in identifying paleomobility between this region and population centers in the Bolivian a

Predicting image blur in proton radiography: Comparisons between measurements and Monte Carlo simulations

Autor: Alexis E. Schach von Wittenau, Maurice B. Aufderheide, Gary Henderson

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 652:901-904

Given the cost and lead-times involved in high-energy proton radiography, it is prudent to model proposed radiographic experiments to see if the images predicted would return useful information. We recently modified our raytracing transmission radiog

Radiographic Capabilities of the MERCURY Monte Carlo Code

Autor: Alexis E. Schach von Wittenau, M. Scott McKinley

Publikováno v: Nuclear Technology. 168:245-248

MERCURY is a modern, parallel, general-purpose Monte Carlo code being developed at the Lawrence Livermore National Laboratory. Recently, a radiographic capability has been added. MERCURY can create...

Publikováno v: Medical Physics. 26:1196-1211

We present a method for condensing the photon energy and angular distributions obtained from Monte Carlo simulations of medical accelerators. This method represents the output as a series of correlated histograms and as such is well-suited for inclus
