Imposing Fine-grain Next Generation Access Control over Database Queries

May 25, 2017
Author(s)
David F. Ferraiolo, Serban I. Gavrila, Gopi Katwala, Joshua D. Roberts
In this paper we describe a system that leverages ANSI/INCITS Next Generation Access Control (NGAC) standard called Next-generation Database Access Control (NDAC) for accessing data in tables, rows, and columns in existing RDBMS products. NDAC imposes

Modeling Thermoplastic Melt Spread Over Different Flooring Materials

July 5, 2010
Author(s)
Kathryn M. Butler, Eugenio Onate, Riccardo Rossi, Julio M. Marti, Sergio R. Idelsohn
The effects of the thermal properties of three flooring materials on the spread rate of polymer melt over the surface were studied using a model based on the Particle Finite Element Method (PFEM). The high thermal conductivity of steel keeps the steel

NBTI: Confusion, Frustration, and Promise?

May 2, 2010
Author(s)
Jason P. Campbell
The negative-bias temperature instability (NBTI) is a reliability problem that, in the last ten years, has risen from relative obscurity to become the most important reliability problem in advanced pMOSFET devices. Even though a significant effort has been

Fermi-Fermi Mixtures in the Strong Attraction Limit

January 31, 2008
Author(s)
Menderes Iskin, Carlos Sa de Melo
The phase diagrams of low density Fermi-Fermi mixtures with equal or unequal masses and equal or unequal populations are described at zero and finite temperatures in the strong attraction limit. In this limit, the Fermi-Fermi mixture can be described by a

Controlling the Dynamics of a Single Atom in Lateral Atom Manipulation

October 8, 2004
Author(s)
Joseph A. Stroscio, Robert Celotta
We study the dynamics of a single Co atom during lateral manipulation on a Cu(111) surface in a low temperature scanning tunneling microscope. The Co binding site locations are revealed in a detailed image that results from lateral Co atom motion within

100 Years of Optical Science and Metrology at NIST

June 1, 2001
Author(s)
William R. Ott
The National Bureau of Standards (NBS) was formed by Congress 100 years ago. The early Bureau was a small organization, founded at the beginning of the age of electricity to promote industrial productivity, commerce, technological progress, and the quality

New Critical Compilations of Atomic Transition Probabilities

October 16, 2008
Author(s)
Wolfgang L. Wiese, Jeffrey R. Fuhr, Daniel E. Kelleher, Larissa Podobedova
At the National Institute of Standards and Technology (NIST), we are continuing our critical evaluation and compilation work on atomic transition probabilities. We have recently concentrated our efforts on the spectra of Na, Mg, Al, Si and S for all stages

New Generation of the NIST Atomic Spectroscopic Databases

January 3, 2005
Author(s)
Y Ralchenko, Jeffrey R. Fuhr, F C. Jou, Alexander Kramida, William C. Martin, Larissa Podobedova, Joseph Reader, E B. Salomon, Jean E. Sansonetti, Wolfgang L. Wiese
The latest advances in development of atomic spectroscopic databases at the National Institute of Standards and Technology (NIST) result from implementation of modern technologies in database management and database-user interaction. Here we report a

Takuma Okumura, Toshiyuki Azuma, Douglas Bennett, W. Bertrand (Randy) Doriese, Malcolm Durkin, Joseph Fowler, Johnathon Gard, Tadashi Hashimoto, Ryota Hayakawa, Yuto Ichinohe, Paul Indelicato, Tadaaki Isobe, Sohtaro Kanda, Daiji Kato, Miho Katsuragawa, Naritoshi Kawamura, Yasushi Kino, Nao Kominato, Yasuhiro Miyake, Kelsey Morgan, Hirofumi Noda, Galen O'Neil, Shinji Okada, Kenichi Okutsu, Nancy Paul, Carl D. Reintsema, Toshiki Sato, Dan Schmidt, Kouichiro Shimomura, Patrick Strasser, Daniel Swetz, Tadayuki Takahashi, Shinichiro Takeda, Soshi Takeshita, Motonobu Tampo, Hideyuki Tatsuno, Tong Xiao-Min, Joel Ullom, Shin Watanabe, Shinya Yamada, Takuma Yamashita
Electronic K x rays emitted by muonic Ar atoms in the gas phase were observed using a superconducting transition-edge-sensor microcalorimeter. The high-precision energy spectra provided a clear signature of the presence of muonic atoms accompanied by a few

Quantum Critical Behavior in Ce(Fe 0.76 Ru 0.24 ) 2 Ge 2

May 7, 2019
Author(s)
Wouter Montfrooij, Tom Heitmann, Yiming Qiu, Shannon M. Watson, Ross Erwin, Wangchun Chen, Yang Zhao, Meigan Aronson, Yingkai Huang, Anne de Visser
Systems with embedded magnetic ions that exhibit a competition between magnetic order and disorder down to absolute zero can display unusual low temperature behaviors of the resistivity, hyperscaling behavior in which the relaxation back to equilibrium
