Development of PMMA composites with tungsten trioxide for improved gamma radiation shielding in microsatellites

Scientific Reports
Satellites are exposed to various types of radiation and extreme temperatures in space, which can lead to damage and malfunctioning of critical components.

The algorithmic and representational uncertainties in green space exposure measurement: conceptualizations and a suite of available methods for mobility-oriented studies

International Journal of Digital Earth
Multiple coupled green space data and representations from Earth observations are available for deriving green space exposure measurements, but they may not be equally effective in health outcome modeling.

Residing in urban areas with higher green space is associated with lower mortality risk: A census-based cohort study with ten years of follow-up.

Environment International, 2021
BACKGROUND Epidemiological studies suggest that residing close to green space reduce mortality rates. We investigated the relationship between long-term exposure to residential green space and non-accidental and cardio-respiratory mortality. METHODS We

“A park is not just a park”: Toward counter-narratives to advance equitable green space policy in the United States

Cities, 2022
Policy advocacy to address socioeconomic and racial/ethnic inequities in access to urban green space (e.g., parks) in the U.S. and elsewhere are often stymied by two dominant narratives on green space reinforced by politicians, business leaders, and ...

Using SPOT Data and FRAGSTAS to Analyze the Relationship between Plant Diversity and Green Space Landscape Patterns in the Tropical Coastal City of Zhanjiang, China

Remote Sensing, 2020
Urban green spaces provide a host of ecosystem services, the quantity and structure of which play an important role in human well-being. Rapid urbanization may modify urban green spaces, having various effects on plant diversity.

Deconstructing urban green justice and well-being: a multi-group structural equation modeling analysis based on the activity space perspective

Frontiers in Public Health
IntroductionAgainst the backdrop of a global shift toward greener cities, equitable access to urban green spaces has increasingly been recognized for its impact on residents’ well-being.

A cross-sectional study examining predictors of visit frequency to local green space and the impact this has on physical activity levels

BMC Public Health, 2016
Background Lack of physical activity (PA) is a growing public health concern. There is a growing body of literature that suggests a positive relationship may exist between the amount of local green space near one’s home and PA levels.

Test and theoretical investigation of fiber-reinforced phosphogypsum short columns with steel- fiber composite bars (SFCB) and BFRP ties under axial compressive load

Results in Engineering
The high brittleness and corrosiveness of phosphogypsum materials limit the structural application of such materials. To address this, PVA fibers and steel-FRP composite bars (SFCB) are synergistically employed to reinforce plain phosphogypsum short ...

Generalized Green Functions and current correlations in the TASEP

, 2011
We study correlation functions of the totally asymmetric simple exclusion process (TASEP) in discrete time with backward sequential update. We prove a determinantal formula for the generalized Green function which describes transitions between positions ...

An Infinite-Dimensional Family of Black-Hole Microstate Geometries [PDF]

, 2010
We construct the first explicit, smooth, horizonless black-hole microstate geometry whose moduli space is described by an arbitrary function of one variable and is thus infinite-dimensional. This is achieved by constructing the scalar Green function on a
