With growing system complexity and closer cyber-physical interaction, there are stronger needs for cyber-physical systems to adapt to the dynamic environment and improve their runtime performance. However, especially for safety-critical systems, the ability of such adaptation and improvement is often restricted by multiple factors, such as limited resources, stringent timing...
Every object emits radiation depending of their temperature. Objects between 300K to 100K emit radiation in the infrared range (1-12µm). These radiations cannot be seen by the human eyes. Infrared detectors find applications in many aspects of life, from night vision and target tracking for homeland security and defense, to...
Does the Russian Federation in the Putin-Medvedev era follow a grand strategy, and if so, what does it look like, and how can we discern the making of Russian grand strategy? However, Russian grand strategy is neither formally codified nor readily accessible, and it remains opaque at best. In this...
In the late Middle Ages, the Italian word fama had a wide semantic range that encompassed such vitally important topics as reputation, honor, community memory, and trustworthiness. In this dissertation, I examine how fama manifested within sodomy prosecutions in late medieval Italy and what insights such prosecutions can give into...
The predominant, categorical system used to classify and diagnose psychiatric disorders suffers from several critical scientific limitations, including extensive comorbidity, unreliability, and disorder heterogeneity. As such, clinical psychological scientists are increasingly moving away from this traditional, categorical system, and toward empirically-based, dimensional, and transdiagnostic alternatives such as the Hierarchical Taxonomy...
Episodic memory provides a means by which we are able to reflect on the past, make decisions about the future, and form a learned identity. Even subtle changes to our memory can have a detrimental impact on our daily lives. Memory declines as we age, and clinically salient impairment is...
In the seventeenth and eighteenth centuries, hundreds of Venetian women began musical training in childhood to become professional musicians, known as figlie di coro (daughters of the choir), in the four charitable Ospedali Maggiori. These women overcame childhood poverty and abandonment to awe prestigious guests with their skills and even...
