1. 3p-Photoabsorption of Free and Bound Cr, Cr^u+^, Mn and Mn^u+^
Published: 1/1/1991
Authors: J T Costello, E T Kennedy, B F Sonntag, Charles W Clark

2. A Comparative Analysis of Cascade Measures for Novelty and Diversity
Published: 2/10/2011
Authors: Ian M Soboroff, Charles L. Clarke, Nick Craswell, Azin Ashkan
Abstract: Traditional editorial effectiveness measures, such as nDCG, remain standard for Web search evaluation. Unfortunately, these traditional measures can inappropriately reward re- dundant information and can fail to reflect the broad range of user needs ...

3. A Green Laser Pointer Hazard
Series: Technical Note (NIST TN)
Report Number: 1668
Published: 8/2/2010
Authors: Jemellie Galang, Alessandro Restelli, Edward W Hagley, Charles W Clark
Abstract: An inexpensive green laser pointer was found to emit 20 mW of infrared radiation during normal use. This is potentially a serious hazard that would not be noticed by most users of such pointers. We find that the problem derives from an unsafe desig ...

4. A High Speed Quantum Communication Testbed
Published: 1/1/2002
Authors: Carl J Williams, X Tang, M Hiekkero, J Rouzaud, R Lu, A Goedecke, Alan L Migdall, A Mink, A Nakassis, Leticia S Pibida, J Wen, Edward W Hagley, Charles W Clark

5. A Hybrid Lagrangian Variational Method for Bose-Einstein Condensates in Optical Lattices
Published: 2/7/2005
Authors: M Edwards, L M DeBeer, M Demenikov, J Galbreath, B Nelson, Charles W Clark
Abstract: Solving the Gross--Pitaevskii (GP) equation describing a Bose--Einstein condensate (BEC) immersed in an optical lattice potential can be a numerically demanding task. We present a variational technique for providing fast, accurate solutions of the G ...

6. A Special Functions Handbook for the Digital Age
Published: 8/1/2011
Authors: Ronald F Boisvert, Charles W Clark, Daniel W Lozier, Frank William John Olver
Abstract: The NIST Digital Library of Mathematical Functions (DLMF) is a reference work providing information on the properties of the special functions of applied mathematics. It is a successor to the highly successful NBS Handbook of Mathematical Functions ( ...

7. A hybrid Lagrangian variational method for Bose-Einstein condensates in optical lattices
Published: 1/1/2005
Authors: Mark Andrew Edwards, L M DeBeer, M Demenikov, J Galbreath, T J Mahaney, B Nelsen, Charles W Clark

8. Accelerating Scientific Discovery through Computation and Visualization
Series: Journal of Research (NIST JRES)
Published: 11/1/2000
Authors: James S Sims, John G Hagedorn, Peter M. Ketcham, Steven G Satterfield, Terence J Griffin, William L George, H A Fowler, B A. am Ende, Howard Hung, Robert B Bohn, John E Koontz, Nicos Martys, Charles E. Bouldin, James A Warren, D L Feder, Charles W Clark, Bernard J Filla, Judith Ellen Terrill
Abstract: The rate of scientific discovery can be accelerated through computation and visualization. This acceleration results from the synergy of expertise, computing tools, and hardware for enabling high performance computation, information science, and visu ...

9. Accurate Determination of Electric-Dipole Matrix Elements in K and Rb From Stark Shift Measurements
Published: 11/30/2007
Authors: B Arora, M S Safronova, Charles W Clark
Abstract: Stark shifts of potassium and rubidium D1 lines have been measured with high precision by Miller et al [1]. In this work, we combine these measurements with our all-order calculations to determine the values of the electric-dipole matrix elements for ...

10. Anomalous Modes Drive Vortex Dynamics in Confined Bose-Einstein Condensates
Published: 1/1/2001
Authors: D L Feder, A A Svidzinsky, A L Fetter, Charles W Clark
