OBJECTIVES The goal of this study was to better characterize the young patient with aortic dissection (AoD). BACKGROUND Aortic dissection is unusual in young patients, and frequently associated with unusual presentations. METHODS Data were collected on 951 patients diagnosed with AoD between January 1996 and November 2001. Two categories of patients, <40 years and >or=40 years, were compare...

In this paper, we propose an efficient beam tracking method for mobility scenario in mmWave-band communications. When the position of the mobile changes in mobility scenario, the base-station needs to perform beam training frequently to track the time-varying channel, thereby spending significant resources for training beams. In order to reduce the training overhead, we propose a new beam train...

The atmospheric aerosol optical depth (AOD) weighted over the solar spectrum is equal to the monochromatic AOD at a certain wavelength. This key wavelength is ~0.7 mum, which is only slightly influenced by air mass and aerosol content. On the basis of this result, simple relations are proposed to predict monochromatic AOD from pyrheliometric data and vice versa. The accuracy achieved is close t...

Financing, payment, and organization and management of alcohol and other drug (AOD) treatment services are closely intertwined and together determine whether people have access to treatment, how the treatment system is designed, and the quality and cost of treatment services. Since the 1960s, changes in these arrangements have driven changes in the delivery of AOD treatment, and recent developm...

Alcohol and other drug (AOD) use is common among adolescents, and its consequences pose important public health problems. Consequently, it is essential to understand the numerous factors that place adolescents at risk for AOD use. These factors include psychological and psychiatric influences (e.g., comorbid psychiatric disorders) as well as peer, environmental, and family factors. The impact o...

One of the main challenges of current climate research is providing Earth-wide characterization of Aerosol Optical Depth (AOD), which indicates the amount of depletion that a beam of radiation undergoes as it passes through the atmosphere. Here, a comprehensive overview will be presented of our ongoing data mining based study aimed at better understanding of spatio-temporal distribution of AOD ...

Correlations between water cloud effective radius (CER) and aerosol optical depth (AOD) from the Moderate Resolution Imaging Spectroradiometer (MODIS) are examined over seven sub-regions in Eastern China for 2003e2012. Water phase cloud is defined as having a cloud top pressure greater than 800 hPa. Significant negative correlation coefficients (r 1⁄4 0.79 w 0.94) between AOD and CER are derive...

Female (C57BL/6xA/J)F(1) mice undergoing thymectomy on day 3 after birth (d3tx) developed autoimmune ovarian disease (AOD) and autoimmune disease of the lacrimal gland. As both were prevented by normal adult CD25(+) T cells, regulatory T cell depletion is responsible for d3tx diseases. AOD began as oophoritis at 3 wk. By 4 wk, AOD progressed to ovarian atrophy with autoantibody response against...

The primary goal of this study was to generate a near-real time (NRT) aerosol optical depth (AOD) product capable of providing a comprehensive understanding of the aerosol spatial distribution over the Pacific Ocean, in order to better monitor and track the trans-Pacific transport of aerosols. Therefore, we developed a NRT product that takes advantage of observations from both low-earth orbitin...

A GIS approach and HJ-1B images were employed to determine the effect of landscape structure on aerosol optical depth (AOD) patterns. Landscape metrics, fractal analysis and contribution analysis were proposed to quantitatively illustrate the impact of land use on AOD patterns. The high correlation between the mean AOD and landscape metrics indicates that both the landscape composition and spat...
