Adolescents are developmentally sensitive to pathways that influence alcohol and other drug (AOD) use. In the absence of guidance, their routine engagement with social media may add a further layer of risk. There are several potential mechanisms for social media use to influence AOD risk, including exposure to peer portrayals of AOD use, socially amplified advertising, misinformation, and preda...

This article describes California community (city, county) uses of local powers and resources to prevent alcohol and other drug (AOD) problems by managing AOD risk environments in retail, public, and social domains. The article presents a promising framework used in several counties dedicated to community environment approaches to prevention. A case example of its application is provided. The f...

Multiple-input multiple-output (MIMO) Rayleigh fading channel with truncated Laplacian azimuth power spectrum (APS) is studied. By using the power correlation matrix of MIMO channel model and the modified Jakes simulator, into which random phases are inserted, the effect of the azimuth spread (AS), angle of departure (AOD) and angle of arrival (AOA) on the spatial correlation coefficient and ch...

Measurements were carried out in 146 limbs with angiographically documented arterial occlusive disease (AOD) and in 85 limbs without AOD. Ankle systolic pressure (AP) was equal to or higher than brachial systolic pressure in limbs without AOD. It was below 82% of the brachial in all limbs with complete occlusion, usually below 50% in those with multiple occlusions, and above 50% in limbs with s...

Aerosol optical depths (AOD) and Angström coefficients over Europe were retrieved using data from the ATSR-2 radiometer on board the ESA satellite ERS-2, for August 1997. Taking advantage of the nadir and forward view of the ATSR-2, the dual view algorithm was used over land to eliminate the influence of the surface reflection. Over sea the AOD was retrieved using only the forward observations....

When the cytochrome-mediated mitochondrial electron transport chain of Neurospora crassa is disrupted, an alternative oxidase encoded by the nuclear aod-1 gene is induced. The alternative oxidase donates electrons directly to oxygen from the ubiquininol pool and is insensitive to chemicals such as antimycin A and KCN that affect the standard electron transport chain. To facilitate isolation of ...

Monte Carlo radiative transfer calculations are performed to examine the forward scattering effects on retrievals of dust aerosol optical depth (AOD) from ground-based instruments. We consider dust aerosols with different AOD, effective radius and imaginary refractive index at 0.5 mm wavelength. The shape of dust aerosols is assumed to be spheroids and the equivalent spheres that preserve both ...

In this paper, the image-based retrieval algorithm of aerosol characteristics and surface reflectance is used to retrieve the AOD from SPOT images. The validation of retrieved AOD is made possible by using the AERONET data. Five SPOT satellite images are used to testify the algorithm. The results show that the RMSE of the retrieved AOD are 0.12 and 0.08 in XS1 and XS2 bands, although the larges...

In this paper, AMIP experiments with changes in all aerosol, sulphate aerosol, and non-sulfate aerosol are used to determine the effects of different aerosol types on the albedo of marine stratocumulus clouds. The main conclusion seems to be that the present day vs. pre-industrial changes in AOD due to anthropogenic aerosol, and hence any changes they induce in in cloud albedo, are small compar...

The Geostationary Ocean Color Imager (GOCI) onboard the Communication, Ocean, and Meteorological Satellite (COMS) is the first multi-channel ocean color imager in geostationary orbit. Hourly GOCI top-of-atmosphere radiance has been available for the retrieval of aerosol optical properties over East Asia since March 2011. This study presents improvements made to the GOCI Yonsei Aerosol Retrieval...
