Neighborhood Diversity and Food Access in a Changing Urban Spatial Structure

, 2020
This paper examines food access disparity in relation to neighborhood diversity, especially race/ethnicity and poverty in a changing intrametropolitan spatial structure, using the Atlanta Metropolitan Statistical Area (MSA) as a case study. With detailed

Seismic morphology and infilling structure of the buried channel system beneath the inner shelf off western Long Island, New York: Accessing clues to palaeo-estuarine and coastal processes

Marine Geology, 2017
Abstract Buried channel systems are important sedimentary repositories for documenting environmental changes in response to eustatic events. Here we investigate the morphology, infilling structure, and evolutionary history of buried channel systems offshore of Long Beach Island, New York, through dense, ultra-high resolution seismic profiles.

Analyzing housing prices in Shanghai with open data: Amenity, accessibility and urban structure

Cities, 2019
Skyrocketing housing prices in China's megacities have generated broad concerns. By integrating open data from Lianjia.com , Dianping.com , Mobike.com , and Baidu Map POI, we analyze spatial patterns of apartment prices and their association with local ...

Vertical Inner Gate Transistors for 4F2 DRAM Cell

IEEE Transactions on Electron Devices, 2020
In this article, we propose a novel cell transistor structure to facilitate the mass production of 4F2 dynamic random access memory (DRAM). 3-D TCAD simulation results show that the proposed structure exhibits a better DRAM operation margin than the ...

Unraveling pH-Dependent Changes in Adsorption Structure of Uranyl on Alumina (012).

Journal of Physical Chemistry Letters
Mitigating uranium transport in groundwater is imperative for ensuring access to clean water across the globe. Here, in situ resonant anomalous X-ray reflectivity is used to investigate the adsorption of uranyl on alumina (012) in acidic aqueous ...
