Failure parameter identification and validation for a dual-phase 780 steel sheet
(Elsevier, 2017-10-01)A hybrid experimental-numerical procedure was implemented to determine the failure surface of a dual-phase 780 steel sheet as a function of the effective plastic strain, triaxiality, and Lode parameter using butterfly ... -
Failure time studies with intermittent observation and losses to follow-up
(Wiley, 2020-12-01)In health research interest often lies in modeling a failure time process but in many cohort studies failure status is only determined at scheduled assessment times. While the assessment times may be fixed upon study entry, ... -
Fair Transition from Defined Benefit to Target Benefit
(Cambridge University Press, 2021)Target benefit (TB) plans that incorporate intergenerational risk sharing have been demonstrated to be welfare improving over the long term. However, there has been little discussion of the short-term benefits for members ... -
Far-field interference of a neutron white beam and the applications to noninvasive phase-contrast imaging
(American Physical Society, 2017-04-26)The phenomenon of interference plays a crucial role in the field of precision measurement science. Waveparticle duality has expanded the well-known interference effects of electromagnetic waves to massive particles. The ... -
Fast and Scalable Solvers for the Fluid Pressure Equations with Separating Solid Boundary Conditions
(Wiley, 2020-05)In this paper, we propose and evaluate fast, scalable approaches for solving the linear complementarity problems (LCP) arising from the fluid pressure equations with separating solid boundary conditions. Specifically, we ... -
Fast assembly of non-thiolated DNA on gold surface at lower pH
(Elsevier, 2013-12-01)In a typical protocol for attaching DNA to a gold electrode, thiolated DNA is incubated with the electrode at neutral pH overnight. Here we report fast adsorption of non-thiolated DNA oligomers on gold electrodes at acidic ... -
Fast Marching-Cubes-Style Volume Evaluation for Level Set Surfaces
(JCGT, 2022-06-30)We present an efficient and accurate volume evaluation method for grid-based level sets that computes the volume of the implicitly represented shape(s) in a manner consistent with Marching Cubes surface reconstruction. We ... -
Fast Molecular Beacon Hybridization in Organic Solvents with Improved Target Specificity
(American Chemical Society, 2010-12-02)DNA hybridization is of tremendous importance in biology, bionanotechnology, and biophysics. Molecular beacons are engineered DNA hairpins with a fluorophore and a quencher labeled on each of the two ends. A target DNA can ... -
Fast Multi-Level Co-Clustering
(2013)We present a new multilevel method for hierarchical co-clustering. The fast multilevel co-clustering method (FMCC) implements a bi-coarsening process on the bipartite graph induced by the feature matrix. It does so in a ... -
Fast pH-assisted functionalization of silver nanoparticles with monothiolated DNA
(Royal Society of Chemistry, 2012-10-18)Attaching monothiolated DNA to silver nanoparticles has been achieved at pH 3.0 in 30 minutes and difficulties associated with DNA attachment to AgNPs at neutral pH have been revealed by studying DNA adsorption kinetics. -
Fast Prefix Adders for Non-uniform Input Arrival Times
(Springer Nature, 2017)We consider the problem of constructing fast and small parallel prefix adders for non-uniform input arrival times. In modern computer chips, adders with up to hundreds of inputs occur frequently, and they are often embedded ... -
Fast quantitation of opioid isomers in human plasma by differential mobility spectrometry/mass spectrometry via SPME/open-port probe sampling interface
(Elsevier, 2017-10-23)Mass spectrometry (MS) based quantitative approaches typically require a thorough sample clean-up and a decent chromatographic step in order to achieve needed figures of merit. However, in most cases, such processes are ... -
Fast Quantitation of Target Analytes in Small Volumes of Complex Samples by Matrix-Compatible Solid-Phase Microextraction Devices
(Wiley, 2017-06-20)Herein we report the development of solid-phase microextraction (SPME) devices designed to perform fast extraction/enrichment of target analytes present in small volumes of complex matrices (i.e. V <= 10 mu L). Micro-sampling ... -
Fast Recognition of BCI-Inefficient Users Using Physiological Features from EEG Signals: A Screening Study of Stroke Patients
(Frontiers, 2018-02-21)Motor imagery (MI) based brain-computer interface (BCI) has been developed as an alternative therapy for stroke rehabilitation. However, experimental evidence demonstrates that a significant portion (10% to 50%) of subjects ... -
A fast variational framework for accurate solid-fluid coupling
(Association for Computing Machinery, 2007-07)Physical simulation has emerged as a compelling animation technique, yet current approaches to coupling simulations of fluids and solids with irregular boundary geometry are inefficient or cannot handle some relevant ... -
Fate of Adsorbed U(VI) during Sulfidization of Lepidocrocite and Hematite
(American Chemical Society, 2017-02-21)The impact on U(VI) adsorbed to lepidocrocite (gamma-FeOOH) and hematite (alpha-Fe2O3) was assessed when exposed to aqueous sulfide (S(II)(aq)) at pH 8.0. With both minerals, competition between S(-II) and U(VI) for surface ... -
