Pulmonary embolism is a common cardiovascular emergency with approximately 600,000 incidents and 200,000 deaths occurring annually in the United States. CT pulmonary angiography (CTPA) has become the reference standard for pulmonary embolism diagnosis, but this technique has several issues with interpretation of the intricate branching structure...

Carotid Intima-Media Thickness (CIMT) measurement with B-mode ultrasound is a noninvasive, sensitive, and highly reproducible technique for cardiovascular risk stratification. Studies have shown that CIMT measurement is correlated with cardiac risk factors and can be used as an independent predictor of future myocardial infarction and stroke risk....

The unique optical properties exhibited by organic compounds with delocalized conjugated pi-electrons make these compounds ideal for fabricating a wide variety of optical and electro-optical devices. Moreover, the process for fabricating these materials into devices is relatively easy. Consequently, these factors have stimulated significant research...

Researchers at Arizona State University have developed organic materials having strong phosphorescent emission in the near infrared region (i.e., from about 650 nm to about 2000 nm, or from about 650 nm to about 1000 nm) using organometallic complexes. These complexes offer high efficiency, wavelength-tunable phosphorescent emitters in the fabrication...

Reliable electrical power is necessary for mission-critical computers and other systems in military and commercial applications. Inclement weather, natural disasters, and other events can disable the local power grid. When grid power is unavailable, an uninterruptible power supply (UPS) can keep key systems powered and operational. However, these...
