1. Overview of the TREC 2011 Web Track
Ian M Soboroff, Nick Craswell, Charles L. Clarke, Gordon Cormack
The TREC Web Track explores and evaluates Web retrieval technology over large collections of Web data.
In its current incarnation, the Web Track has been active for two years. For TREC 2010, the track
includes three tasks: 1) an adhoc retrieval t ...
2. SURF III: A flexible Synchrotron Radiation Source for Radiometry and Research
Uwe Arp, Charles W Clark, Lu Deng, Nadir Sabirovich Faradzhev, Alex P. Farrell, Mitchell L. Furst, Steven E Grantham, Edward Walter Hagley, Shannon Bradley Hill, Thomas B Lucatorto, Ping-Shine Shaw, Charles S Tarrio, Robert Edward Vest
The calculability of synchrotron radiation (SR) makes electron storage rings wonderful light sources for radiometry. The broadband nature of SR allows coverage of the whole spectral region from the x-ray to the far-infrared. Compact low-energy storag ...
3. A Special Functions Handbook for the Digital Age
Ronald F Boisvert, Charles W Clark, Daniel W Lozier, Frank William John Olver
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 ( ...
4. A Comparative Analysis of Cascade Measures for Novelty and Diversity
Ian M Soboroff, Charles L. Clarke, Nick Craswell, Azin Ashkan
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 ...
5. A Green Laser Pointer Hazard
Technical Note (NIST TN)
Jemellie Galang, Alessandro Restelli, Edward Walter Hagley, Charles W Clark
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 ...
6. Ettore Majorana and the birth of autoionization
Charles W Clark, Ennio Arimondo, William C. Martin
In the early days of theoretical atomic spectroscopy, Ettore Majorana (1906-1938?) solved several
outstanding problems by developing the theory of autoionization. Later literature makes only
sporadic references to this accomplishment. Reviewing ...
7. The NIST Handbook of Mathematical Functions
Frank William John Olver, Daniel W Lozier, Ronald F Boisvert, Charles W Clark
The NIST Handbook of Mathematical Functions supplies validated reference information in 36 chapters on a wide selection of important mathematical functions, covering the properties necessary for their use in scientific applications, together with gen ...
8. Ultracold Atom Spin Field Effect Transistor
Jay Vaishnav, Julius Ruseckas, Charles W Clark, Gediminas Juzelunas
We propose a method of constructing cold atom analogs of the spintronic device known as the Datta-Das transistor (DDT), which despite its seminal conceptual role in spintronics, has never been successfully realized with electrons. We propose two alte ...
9. Collisional cooling of ultra-cold atom ensembles using Feshbach resonances
Ludwig G. Mathey, Eite Tiesinga, Paul S Julienne, Charles W Clark
We propose a new type of cooling mechanism for ultra-cold fermionic atom ensembles, which capitalizes on the energy dependence of inelastic collisions in the presence of a Feshbach resonance. We first discuss the case of a single magnetic reson ...
10. Counterflow and paired superfluidity in one-dimensional Bose mixtures in optical lattices
Anzi Hu, Ludwig G. Mathey, Ippei Danshita, Eite Tiesinga, Carl J Williams, Charles W Clark
We study the quantum phases of mixtures of ultra-cold bosonic atoms held in an optical lattice that confines motion or hopping to one spatial dimension. The phases are found by using Tomonaga-Luttinger liquid theory as well as the numerical method of ...
