Maternal Nutrition at Conception Modulates DNA Methylation of Human Metastable Epialleles
We show that significant seasonal variations in methyl-donor nutrient intake of mothers around the time of conception influence 13 relevant plasma biomarkers. Our results demonstrate that maternal nutritional status during…

Auroral Ionospheric F Region Density Cavity Formation and Evolution: Mica Campaign Results
Auroral ionospheric F region density depletions observed by PFISR (Poker Flat Incoherent Scatter Radar) during the MICA (Magnetosphere-Ionosphere Coupling in the Alfvén Resonator) sounding rocket campaign are critically examined alongside complementary numerical…

Experimental Demonstration of a Broadband All-Dielectric Metamaterial Perfect Reflector
Here we present the demonstration of a single-negative all-dielectric metamaterial that possesses peak reflectance over 99% and an average reflectance over 98% across a 200 nm wide bandwidth in the short-wavelength…

No Association between Germline Variation in Catechol-O-Methyltransferase and Colorectal Cancer Survival in Postmenopausal Women
Because catechol-O-methyltransferase (COMT; 22q11.21) activity is an important component of estrogen-mediated carcinogenesis, we hypothesized that germline variation in COMT may be associated with CRC survival.

Sudemycin E Influences Alternative Splicing and Changes Chromatin Modifications
To determine the effect on gene expression, we performed genome-wide array analysis. Sudemycin E first causes a rapid change in alternative pre-messenger RNA splicing, which is later followed by changes…

Advice for Mathematical Argumentation
“Telling” can be an effective tool in helping students engage in intellectually demanding argumentation and productive behavior.

Generalized Effective-Medium Theory for Metamaterials
We present an effective-medium model for calculating the frequency-dependent effective permittivity ε(ω) and permeability μ(ω) of metamaterial composites containing spherical particles with arbitrary permittivity and permeability.

ISOMER: Informative Segment Observations for Multimedia Event Recounting
This paper describes a system for multimedia event detection and recounting. The goal is to detect a high level event class in unconstrained web videos and generate event oriented summarization…

Multi-Modal Image Retrieval for Complex Queries Using Small Codes
We propose a unified framework for image retrieval capable of handling complex and descriptive queries of multiple modalities in a scalable manner.

Computational thinking practices: Analyzing and modeling a critical domain in computer science education
This paper discusses the design process used to develop an assessment of computational thinking to support the adoption of a high school computer science curriculum.

Incoherent Scatter Radar-FAST Satellite Common Volume Observations of Upflow-to-Outflow Conversion
Measurements have been combined with all-sky images, polar convection measurements, and FAST particle and field measurements to quantify the contribution of different magnetosphere-ionosphere coupling processes to the extraction efficiency of…

Who is where? Characteristics of deaf and hard-of-hearing students in regular and special schools
A secondary analysis of the National Longitudinal Transition Study 2 database was conducted to examine differences in the characteristics of students who attended special schools, such as schools for the…
