Digital Games, Design, and Learning: A Systematic Review and Meta-Analysis (Brief)
The present meta-analysis synthesized research on digital games to systematically examine their efficacy for learning. We focused on research published between 2000 and 2012 in light of the dramatic evolution of digital games for learning over the past decade.

Ionospheric Ion Temperature Forecasting in Multiples of 27 Days
In this study we demonstrate that over a 3 year period, ionospheric variability observed from Poker Flat, Alaska, has, in fact, a high degree of long-term predictability.

Characteristics of Large-Scale Wave Structure Observed from African and Southeast Asian Longitudinal Sectors
In this scenario, a comprehensive study is carried out, for the first time, on the spatial and temporal characteristics of LSWS observed in spatial domain over African and Southeast Asian longitudinal sectors during the year 2011.

Digital Games, Design, and Learning: A Systematic Review and Meta-Analysis (Executive Summary)
We synthesize comparisons of game conditions versus non-game conditions (i.e., media comparisons) as well as comparisons of augmented game designs versus equivalent standard game designs (i.e., value-added comparisons).

mRNA Splicing-Modulatory Pharmacophores: The Total Synthesis of Herboxidiene, a Pladienolide-Herboxidiene Hybrid Analog and Related Derivatives
We report an improved enantioselective synthesis of herboxidiene and the first report of its biologically active totally synthetic analog: 6-norherboxidiene.

Distributed Coverage with Mobile Robots on a Graph: Locational Optimization and Equal-Mass Partitioning
This paper presents decentralized algorithms for coverage with mobile robots on a graph. We use distributed vertex substitution for locational optimization and equal mass partitioning, and the controllers minimize the corresponding cost functions.

Automatic 3D Change Detection for Glaucoma Diagnosis
We propose an automatic approach for detecting these changes in 3D models reconstructed from fundus images of the same patient taken at different times.

Tracking Elevated Pollution Layers with a Newly Developed Hyperspectral Sun/Sky Spectrometer (4STAR): Results from the TCAP 2012 and 2013 Campaigns
We compare results with coincident measurements. We find 0.045 g/cm2 (4.2%) negative bias and 0.28 g/cm2 (26.3%) root-mean-square difference (RMSD) in water vapor layer comparison with an in situ hygrometer and an overall RMSD of 1.28 g/m3 (38%) water vapor amount in profile by profile comparisons, with differences distributed evenly around zero.

Simulations for STEM Learning: A Systematic Review and Meta-Analysis (Brief)
This review addresses a gap in the current research literature on computer-based simulations for STEM learning.

Influence of Systemic Interleukin-6 on the Inverse Association between Your-Choice American Heart Diet and a 41-Year Mortality Risk from Coronary Heart Disease among Men
Our premise is systemic inflammation measured as plasma interleukin-6 levels medicates the association between whole diet and long-term mortality risk from coronary heart disease independent of genes.

Simulations for STEM Learning: Systematic Review and Meta-Analysis (Executive Summary)
This executive summary presents an overview of the process and initial findings of a systematic review and meta-analysis of the literature on computer simulations for K–12 science, technology, engineering, and mathematics (STEM) learning topics.

Addition of Escherichia coli K-12 Growth Observation and Gene Essentiality Data to the Ecocyc Database
We have integrated data on the growth or nongrowth of E. coli K-12 obtained from published observations using a variety of individual media and from high-throughput phenotype microarrays into the EcoCyc database.
