- Description:
- 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...

- Description:
- The vaudeville remains an oft-overlooked genre of French song that was popularized by Paris’s fairground theaters and street singers on the Pont Neuf. Many histories of French music point to the middle of the eighteenth century as the period when the vaudeville began its rapid disappearance from the city’s musical...

- Description:
- Prior studies about restatements generally examine outcomes under assumed auditor responsibility. Surprisingly, however, about 20% of the restatements obtained from Audit Analytics correspond to cases where the current auditor was not engaged during the misstatement period. I refer to these cases as uninvolved. The first chapter examines current literature findings...

- Description:
- Decision making is an essential and indispensable element in everyday life. It is posited that parallel, distinct systems subserving deliberative, goal-directed control and automatic, habitual control underlie decision making. Computational accounts suggest that model-based and model-free learning strategies give rise to these two systems respectively. The model-based system is a...

- Description:
- For years, neuroscientists have strived to understand memory consolidation, where salient memories are sorted and organized into distributed cortical networks for long-term storage. A large body of sleep research suggests that slow-wave sleep is an optimal opportunity for memory consolidation, and that consolidation is driven, at least in part, by...

- Description:
- This thesis deals with modeling long-term deformation and failure of concrete and shale structures. First concrete structures are studied. For concrete structures, design lifetime of over a hundred years is required. Shrinkage, swelling, creep and Alkali-silica reaction are significant parts of the long-term deformation of concrete and are studied here....

- Solvent-rich polyelectrolyte complexes display a wide range of rheological properties, when different environmental parameters are applied. Due to the low energy barrier of the complexation (~10 kT), these materials possess tunable properties, with the states of these materials varying from Newtonian liquids to very tough hydrogels. This thesis aims to...

- Some of the oldest drugs targeting metabolism are the antifolates such as aminopterin and methotrexate (MTX). MTX started being used in the 1950s to treat rheumatoid arthritis. Aminopterin and MTX both target one carbon metabolism and inhibit proliferation of cells. MTX was a potent inhibitor of inflammation, because it prevented...
