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 ... -
Fatigue characteristics and modeling of cast and cast-forged ZK60 magnesium alloy
(Elsevier, 2019-01-01)The fatigue behavior of as-cast and cast-forged ZK60 magnesium alloy was investigated via fully-reversed strain controlled fatigue tests at different strain amplitudes. Microstructure analysis, texture measurement, and SEM ... -
Fatigue characterization and modeling of AZ31B magnesium alloy spot-welds
(Elsevier, 2014-07-01)Cyclic behavior of AZ31B spot-welds was studied using different specimen configurations, and compared with steel and aluminum spot-welds. Fatigue strength of magnesium spot-welds was similar to aluminum and less than steel. ... -
Fatigue Life Prediction of an Automotive Chassis System with Combined Hardening Material Model
(Society of Automotive Engineers, 2016-04-05)The choice of an appropriate material model with parameters derived from testing and proper modeling of stress-strain response during cyclic loading are the critical steps for accurate fatigue-life prediction of complex ... -
Fatigue related impairments in oculomotor control are prevented by caffeine
(Nature, 2016-05-25)Strenuous exercise can result in an inability of the central nervous system to drive skeletal muscle effectively, a phenomenon known as central fatigue. The impact of central fatigue on the oculomotor system is currently ... -
Fear of compassion is associated with treatment ambivalence and negative expectations for treatment in people with anxiety
(British Psychological Society, 2021-06-12)Objectives. Fears of compassion are hypothesized to be associated with treatment attitudes, but this relationship has not yet been explored. Methods. Measures of fear of compassion and treatment expectations and ambivalence ... -
Fearful, surprised, happy, and angry facial expressions modulate gaze-oriented attention: behavioral and ERP evidence.
(Taylor & Francis, 2013-09-18)The impact of emotions on gaze-oriented attention was investigated in non-anxious participants. A neutral face cue with straight gaze was presented, which then averted its gaze to the side while remaining neutral or ... -
Fears of receiving compassion from others predict safety behaviour use in social anxiety disorder over and above fears of negative self-portrayal
(Elsevier, 2021-05)Why do people with social anxiety disorder (SAD) engage in the use of safety behaviours? While past research has established that fears of negative self-portrayal are strongly associated with safety behaviour use in SAD, ... -
Feasibility of Injecting Large Volumes of CO2 into Aquifers
(Elsevier, 2009-02)Although it is recognized that deep aquifers offer a very large potential storage capacity for CO2 sequestration it is not clear how to fill the storage with a large volume of CO2 in a relatively short period of time. The ... -
Feature identification in time series data sets
(Elsevier, 2019-05)We present a computationally inexpensive, flexible feature identification method which uses a comparison of time series to identify a rank-ordered set of features in geophysically-sourced data sets. Many physical phenomena ... -
Feeling Precarious: Millennial Women and Work
(Sage, 2015-12-18)In Precarious Life (2004), Judith Butler writes about how a shared sense of fear and vulnerability opens the possibility of recognizing interdependency. This is a wider understanding of precarity than is often present in ...
