Spatiotemporal relationship between Himawari-8 hourly columnar aerosol optical depth (AOD) and ground-level PM mass concentration in mainland China.

Himawari-8 aerosol products have been widely used to estimate the near-surface hourly PM concentrations due to the high temporal resolution. However, most studies focus on the evaluation model. As the foundation of the estimation, the relationship between near-surface PM and columnar aerosol optical depth (AOD) has not been comprehensively investigated.

A Reply to "Comments on "A New Elliptical Model for Device-Free Localization"".

Recently, a comment paper on "A New Elliptical Model for Device-Free Localization" (Sensors 2016, 16, 577) has been presented, and the authors have provided a modified model. However, there are still some misunderstandings. In this reply, we further explain the proposed elliptical model in (Sensors 2016, 16, 577) to make it more understandable.

Iodine-131 in Helicobacter pylori-positive patients: preliminary accidental finding and in differentiated thyroid cancer.

Objective: To investigate the eradicate effect of Helicobacter pylori in differentiated thyroid cancer patients who underwent I therapy.

Materials And Methods: A total of 130 patients with differentiated thyroid cancer underwent I treatment. None of the patients had a history of stomach-related diseases.

A New Elliptical Model for Device-Free Localization.

Device-free localization (DFL) based on wireless sensor networks (WSNs) is expected to detect and locate a person without the need for any wireless devices. Radio tomographic imaging (RTI) has attracted wide attention from researchers as an emerging important technology in WSNs. However, there is much room for improvement in localization estimation accuracy.

A study of the coupling relationship between concrete surface temperature and concrete surface emissivity in natural conditions.

Land surface emissivity (LSE) has already been recognized as a crucial parameter for the determination of land surface temperature (LST). There is an ill-posed problem for the retrieval of LST and LSE. And laboratory-based emissivity is measured in natural constant conditions, which is limited in the application in thermal remote sensing.
