Quantitative Susceptibility Mapping by Inversion of a Perturbation Field Model: Correlation with Brain Iron in Normal Aging
We present a method for quantifying susceptibility by inversion of a perturbation model, or “QSIP.” The perturbation model relates phase to susceptibility using a kernel calculated in the spatial domain, in contrast to previous Fourier-based techniques.

Re-Ranking by Multi-Feature Fusion with Diffusion for Image Retrieval
We present a re-ranking algorithm for image retrieval by fusing multi-feature information. We utilize pairwise similarity scores between images to exploit the underlying relationships among images.

Variation in the Human Immune System Is Largely Driven by Non-Heritable Influences
To assess the relative contribution of heritable versus non-heritable factors, we have performed a systems-level analysis of 210 healthy twins between 8 and 82 years of age.

Characterization, HPLC Method Development and Impurity Identification for 3,4,3-Li(1,2-HOPO), a Potent Actinide Chelator for Radionuclide Decorporation
Derivatization of the target ligand in situ with Fe(III) chloride provided a single homogeneous iron-complex that can readily be detected and analyzed by HPLC.

Feature Fusion by Similarity Regression for Logo Retrieval
We propose a simple yet effective multi-feature fusion approach based on regression models for logo retrieval.

Reading and Math Achievement Profiles and Longitudinal Growth Trajectories of Children with an Autism Spectrum Disorder
This study examined the reading and math achievement profiles and longitudinal growth trajectories of a nationally representative sample of children with an autism spectrum disorder.

Transition to Adulthood: Employment, Education, and Disengagement in Individuals with Autism Spectrum Disorders
We found variations in disproportionate transition patterns by gender, family income, functional cognitive skills, and conversational skills.

Fast and Ultrafast Kelvin Wave Modulations of the Equatorial Evening F Region Vertical Drift and Spread F Development
In this paper, we investigate the role of eastward and upward propagating fast and ultrafast Kelvin waves in the day-to-day variability of equatorial evening prereversal vertical drift and post sunset generation of spread F/plasma bubble irregularities.

Measuring and Statistically Testing the Size of the Effect of a Chemical Compound on a Continuous in-Vitro Pharmacological Response through a New Statistical Model of Response Detection Limit
We used a linearized version of this equation to define a measure of pharmacological effect size, and use this measure to rank the investigated compounds in order of their overall capability to produce strong responses.

BU08073 a Buprenorphine Analog with Partial Agonist Activity at mu Receptors in vitro but Long-Lasting Opioid Antagonist Activity in vivo in Mice
Structure activity studies were conducted to design buprenorphine analogues with high affinity at each of these receptors and to characterize them in in vitro and in vivo assays.

De-Correlating CNN Features for Generative Classification
The proposed approach to solving this problem builds on the idea of training LDA classifiers using only class specific foreground images and a large collection of unlabelled images.

Evidence for Effective Uses of Dynamic Visualisations in Science Curriculum Materials
We review research to clarify the impacts of dynamic visualisations and to identify instructional scaffolds that mediate their success.
