Applications of Sinkhorn Balancingto Counting Problems

July 1, 2004
Author(s)
Isabel M. Beichl, F Sullivan
We describe a gneral Monte Carlo technique based on work of Knuth for estimating the size of trees in backtrack algorithms. This method, based on importance sampling, is used to estimate the number of partial and complete matchings in a bipartite graph

Applications of Sinkhorn Balancing: The Monomer-Dimer Problem

January 30, 2004
Author(s)
Isabel M. Beichl, Francis Sullivan
We describe a general Monte Carlo technique based on work of Knuth for estimating the size of trees in backtrack algorithms. This method, based on importance sampling, is used to estimate the number of partial and complete matchings in a bipartite graph

The creation and study of Bose-Einstein condensation in a cold alkali vapor

September 1, 1997
Author(s)
C E. Wieman, Eric A. Cornell, Deborah S. Jin, J R. Ensher
Bose-Einstein condensation in a gas resulted form the combination of research in laser cooling and trapping, the study of spin polarized hydrogen, and the investigation of atomic collisions at very low temperatures. After discussing how these advances led

Handheld Real-Time PCR Device

January 26, 2016
Author(s)
Christian D. Ahrberg, Robert Ilic, Andreas Manz, Pavel Neu?il
Here we report one of the smallest real-time PCR system up to date with approximate size of 100 mm × 60 mm × 33 mm. The system is an autonomous unit requiring an external 12 V power supply. Four simultaneous reactions are performed in form of virtual

NIST ADVANCES IN COMPUTER-AIDED AND COMPUTATIONAL METHODS IN WIND ENGINEERING

October 19, 2012
Author(s)
Dong Hun Yeo, Franklin T. Lombardo, Dilip K. Banerjee, Eric J. Letvin, Emil Simiu, Marc L. Levitan, Florian A. Potra
The paper summarizes recent research and development of computer-aided and computational methods in wind engineering at the National Institute of Standards and Technology (NIST). Specific topics to be covered include: 1. Time-domain database-assisted

An Interaction-based Test Sequence Generation Approach for Testing Web Applications

December 3, 2008
Author(s)
Wenhua Wang, Sreedevi Sampath, Yu Lei, Raghu N. Kacker
Web applications often use dynamic pages that interact with each other by accessing shared objects, e.g., session objects. Interactions between dynamic pages need to be carefully tested, as they may give rise to subtle faults that cannot be detected by

Measurement of Dynamic Properties in Thin-Films

December 1, 2001
Author(s)
Thomas J. Silva
I present a summary of the various techniques available for the determination of response times in magnetic recording head materials. In addition, I derive useful equations for the interpretation of data in the context of the Landau-Lifshitz-Gilbert

Handbook of Frequency Stability Analysis

July 1, 2008
Author(s)
William Riley, David A. Howe
This handbook, which can be used as both a tutorial and a reference, describes practical techniques for frequency stability analysis. It covers the definitions of frequency stability, measuring systems and data formats, pre-processing steps, analysis tools

2022 OpenFAD Evaluation Plan (Open Fine-grained Activity Detection)

October 2, 2023
Author(s)
Yooyoung Lee, Jonathan Fiscus, Lukas Diduch, Jeffery Byrne
This document describes an evaluation of the 2022 Open Fine-grained Activity Detection (OpenFAD) challenge. The evaluation plan covers resources, task definitions, task conditions, file formats for system inputs and outputs, evaluation metrics, scoring

Time Transfer Using a Satellite Navigation System

January 1, 2013
Author(s)
Judah Levine
Article does not have an abstract. It was solicited by the editors of the yearbook and was written based on their detailed comments about the topics to be covered, the technical detail, etc. It is intended for high-school students and contains material

SiO 2 /Si 3 N 4 /A1 2 O 3 Stacks on Silicon for Scaled-Down Memory Devices: Effects of Interfaces and Thermal Annealing

October 12, 2021
Author(s)
M Lisiansky, A Heiman, M Kovler, Y Roizin, Igor Levin, A Gladkikh, M Oksman, R Edrei, A A. Hofman, Y Shnieder, T Claasen
Effects of interfaces and thermal annealing on the electrical performance of the SiO2/Si3N4/A12O3 (ONA) stacks in non-volatile memory devices were investigated. Structural and electrical characterization demonstrated the principal role of the Si3N4/A12O3

Photoelectron spectroscopy of wet and gaseous samples through electron transparent graphene membranes

September 22, 2014
Author(s)
Jurgen Kraus, Robert Reichelt, Sebastian Gunther, Luca Gregoratti, Tang Lin Teo, Maya Kiskinova, Alexander Yulaev, Ivan Vlassiouk, Andrei Kolmakov
Photoelectron spectroscopy (PES) and microscopy are highly demanded for exploring morphologically complex solid-gas and solid-liquid interfaces under realistic conditions but the very small electron mean free path inside the dense media imposes serious
