Energy Gaps in Graphene Nanoribbons [PDF]

Physical Review Letters, 2006
Based on a first-principles approach, we present scaling rules for the band gaps of graphene nanoribbons (GNRs) as a function of their widths. The GNRs considered have either armchair or zigzag shaped edges on both sides with hydrogen passivation.

Four Responsibility Gaps with Artificial Intelligence: Why they Matter and How to Address them

Philosophy & Technology, 2021
The notion of “responsibility gap” with artificial intelligence (AI) was originally introduced in the philosophical debate to indicate the concern that “learning automata” may make more difficult or impossible to attribute moral culpability to persons ...

Active learning narrows achievement gaps for underrepresented students in undergraduate science, technology, engineering, and math

Proceedings of the National Academy of Sciences of the United States of America, 2020
Significance Achievement gaps increase income inequality and decrease workplace diversity by contributing to the attrition of underrepresented students from science, technology, engineering, and mathematics (STEM) majors. We collected data on exam scores

A Ubiquitous Sensor Network Platform for Integrating Smart Devices into the Semantic Sensor Web

Sensors, 2014
Ongoing Sensor Web developments make a growing amount of heterogeneous sensor data available to smart devices. This is generating an increasing demand for homogeneous mechanisms to access, publish and share real-world information.

Algebraic spectral gaps [PDF]

, 2011
For the one-dimensional Schr\"odinger equation, some real intervals with no eigenvalues (the spectral gaps) may be obtained rather systematically with a method proposed by H. Giacomini and A. Mouchet in 2007. The present article provides some alternative

Gap Junctions [PDF]

Cold Spring Harbor Perspectives in Biology, 2009
Gap junctions are aggregates of intercellular channels that permit direct cell-cell transfer of ions and small molecules. Initially described as low-resistance ion pathways joining excitable cells (nerve and muscle), gap junctions are found joining virtually all cells in solid tissues.

A novel recruiting and surveying method: Participatory research during a Pacific Islander community’s traditional cultural event

Gateways, 2015
Little is known about the health status of Marshallese, a Pacific Islander subpopulation living in the United States. The Marshallese have established a growing community in Northwest Arkansas, providing a unique opportunity for increasing knowledge ...

Gaps between logs [PDF]

, 2013
We calculate the limiting gap distribution for the fractional parts of log n, where n runs through all positive integers. By rescaling the sequence, the proof quickly reduces to an argument used by Barra and Gaspard in the context of level spacing ...
