Reduction in mobility and COVID-19 transmission

Nature Communications, 2021
In response to the COVID-19 pandemic, countries have sought to control SARS-CoV-2 transmission by restricting population movement through social distancing interventions, thus reducing the number of contacts.

Neighborhood walkability, physical activity, and walking for transportation: A cross-sectional study of older adults living on low income

BMC Geriatrics, 2017
Background Walking, and in particular, outdoor walking, is the most common form of physical activity for older adults. To date, no study investigated the association between the neighborhood built environment and physical activity habits of older adults ...

Mobile crowdsensing with mobile agents [PDF]

Autonomous Agents and Multi-Agent Systems, 2015
We introduce mobile agents for mobile crowdsensing. Crowdsensing campaigns are designed through different roles that are implemented as mobile agents. The role-based tasks of mobile agents include collecting data, analyzing data and sharing data in the campaign.

Revealing Charge Carrier Mobility and Defect Densities in Metal Halide Perovskites via Space-Charge-Limited Current Measurements

ACS Energy Letters, 2021
Space-charge-limited current (SCLC) measurements have been widely used to study the charge carrier mobility and trap density in semiconductors. However, their applicability to metal halide perovskites is not straightforward, due to the mixed ionic and ...

Are we missing the sitting? Agreement between accelerometer non-wear time validation methods used with older adults’ data

Cogent Medicine, 2017
We used Bland Altman plots to compare agreement between a self-report diary and five different non-wear time algorithms [an algorithm that uses ≥60 min of consecutive zeroes (Troiano) and four variations of an algorithm that uses ≥90 min of consecutive ...

Understanding Immobility: Moving Beyond the Mobility Bias in Migration Studies

International Migration Review, 2020
This article suggests that there is a mobility bias in migration research: by focusing on the “drivers” of migration — the forces that lead to the initiation and perpetuation of migration flows — migration theories neglect the countervailing structural ...
