Comparing Mostly-copying and Mark-sweep Conservative Collection
(Association for Computing Machinery, 1998)Many high-level language compilers generate C code and then invoke a C compiler for code generation. To date, most, of these compilers link the resulting code against a conservative mark-sweep garbage collector in order ... -
Comparing Neanderthal and Modern Human Long Bone Loading History from Cross-Sectional Geometry
(John Wiley & Sons, 2003)We evaluate here efforts to compare archaic and modern human limb loading from long bone cross sectional. Recent studies find that cross sectional properties (I, J, Z) calculated from second moments of area (SMA) are similar ... -
Comparing Organizational Sampling Frames
(Johnson Graduate School of Management, Cornell University, 1990)We compare and contrast the representativeness, practicality, and cost of five generally available and commonly used organizational samping frames: direct enumeration, unemployment insurance (UI) forms, Dun and Bradstreet's ... -
Comparing reactive and memory-one strategies of direct reciprocity
(Nature Publishing Group, 2016)Direct reciprocity is a mechanism for the evolution of cooperation based on repeated interactions. When individuals meet repeatedly, they can use conditional strategies to enforce cooperative outcomes that would not be ... -
Comparing research investment to United Kingdom institutions and published outputs for tuberculosis, HIV and malaria: a systematic analysis across 1997–2013
(BioMed Central, 2015)Background: The “Unfinished Agenda” of infectious diseases is of great importance to policymakers and research funding agencies that require ongoing research evidence on their effective management. Journal publications ... -
Comparing Significance Levels of Independent Studies
(American Psychological Association, 1979)Methods for comparing two or more statistical significance (p) levels are described; these methods are more rigorous, systematic, and informative than the comparisons that are commonly made by using a significant/not ... -
Comparing simulations and observations of the Ly alpha forest. I. Methodology
(American Astronomical Society, 2002) -
Comparing Within- and Between-Subjects Studies
(Sage, 1980)Studies employing within-subjects designs may be compared with those employing between-subjects designs in a variety of ways. We discuss and illustrate the comparisons of variabilities, including within-condition variances ... -
Comparison and Optimization of hiPSC Forebrain Cortical Differentiation Protocols
(Public Library of Science, 2014)Several protocols have been developed for human induced pluripotent stem cell neuronal differentiation. We compare several methods for forebrain cortical neuronal differentiation by assessing cell morphology, immunostaining ... -
Comparison between simulated and observed LHC beam backgrounds in the ATLAS experiment at Ebeam=4 TeV
(IOP Publishing, 2018-12-04)Results of dedicated Monte Carlo simulations of beam-induced background (BIB) in the ATLAS experiment at the Large Hadron Collider (LHC) are presented and compared with data recorded in 2012. During normal physics operation ... -
Comparison of Adjoint and Analytical Bayesian Inversion Methods for Constraining Asian Sources of Carbon Monoxide Using Satellite (MOPITT) Measurements of CO Columns
(American Geophysical Union, 2009)We apply the adjoint of an atmospheric chemical transport model (GEOS-Chem CTM) to constrain Asian sources of carbon monoxide (CO) with 2° × 2.5° spatial resolution using Measurement of Pollution in the Troposphere (MOPITT) ... -
Comparison of Apparent Diffusion Coefficient and T2 Relaxation Time Variation Patterns in Assessment of Age and Disc Level Related Intervertebral Disc Changes
(Public Library of Science, 2013)Purpose To compare the variation patterns of ADC and T2 values in different age and intervertebral disc (IVD) levels, thus to identify their sensitivities in assessing age and disc level related IVDs changes. Materials and ... -
A Comparison of Beginning and Advanced Engineering Students’ Description of Information Skills
(2015)Objective – The purpose of this research was to examine how beginning and advanced level engineering students report use of information when completing an engineering design process. This information is important for ... -
Comparison of Capacity Retention Rates During Cycling of Quinone-Bromide Flow Batteries
(Cambridge University Press (CUP), 2016)We use cyclic charge-discharge experiments to evaluate the capacity retention rates of two quinone-bromide flow batteries (QBFBs). These aqueous QBFBs use a negative electrolyte containing either anthraquinone-2,7-disulfonic ... -
Comparison of CE-FDG-PET/CT with CE-FDG-PET/MR in the evaluation of osseous metastases in breast cancer patients
(Nature Publishing Group, 2015)Background: Despite improvements in treatments, metastatic breast cancer remains difficult to cure. Bones constitute the most common site of first-time recurrence, occurring in 40–75% of cases. Therefore, evaluation for ... -
Comparison of Full and Empirical Bayes Approaches for Inferring Sea-Level Changes From Tide-Gauge Data
(American Geophysical Union (AGU), 2017-03)Tide‐gauge data are one of the longest instrumental records of the ocean, but these data can be noisy, gappy, and biased. Previous studies have used empirical Bayes methods to infer the sea‐level field from tide‐gauge ... -
Comparison of Growth Morphology in Ge (001) Homoepitaxy Using Pulsed Laser Deposition and MBE
(Materials Research Society, 2003)Differences in the homoepitaxy of Ge(001) are explored using a dual MBE/PLD deposition system. With identical substrate preparation, temperature calibration, background pressure and analysis, the system provides a unique ... -
Comparison of Heart Rate Monitor and Accelerometer for Measuring Energy Expenditure Under Field Conditions
(John Wiley & Sons, 2009)Life history models predict differential energy allocation patterns among growth, maintenance, and reproduction under varying ecological conditions. The assessment of energy expenditure is one important tool in quantifying ... -
Comparison of high- and low-state X-ray spectra in the type 1.5 quasi-stellar object 2MASS 0918+2117
(Oxford University Press (OUP), 2007)When observed by XMM–Newton in 2003, the type 1.5 quasi-stellar object 2MASS 0918+2117 was found to be in a low state, with an X-ray flux approximately four to five times fainter than during an earlier Chandra observation. ... -
Comparison of human gastrocnemius forces predicted by Hill-type muscle models and estimated from ultrasound images
(The Company of Biologists, 2017)Hill-type models are ubiquitous in the field of biomechanics, providing estimates of a muscle's force as a function of its activation state and its assumed force–length and force–velocity properties. However, despite their ...
