We start from a set of users communicating over a Gaussian multiple access wire-tap channel with confidential messages, where users attempt to transmit private messages to a legitimate receiver in the presence of an eavesdropper. While prior work focused on the case where the users were cooperative, we assume that...
ABSTRACT In the past two decades, the number of African and Afro-Caribbean immigrants arriving in the U.S. has been increasing. Black immigrants (36% of whom migrated from Africa and 50% from the Caribbean since 2000) now account for nearly 10% of the Black population in the U.S. This growing demographic...
On March 11, 1966, Indonesian President Soekarno suddenly transferred executive power to the Army, which has played a role in the Indonesian state and society since the late 1950s. This act replaced Soekarno’s own government with a military dictatorship dubbed the New Order, which lasted for nearly 32 years. Why...
The planarian flatworm Schmidtea mediterranea is capable of recovery from nearly any injury, including regenerating an entire brain after decapitation, made possible by a pool of pluripotent stem cells which maintain all of the worm’s tissues into adulthood. However, the signals that control the production of new neurons in these...
Organic solar cells (OSC) are a next generation solar energy technology that offers the advantages of scalable fabrication, light weight, flexibility, and earth-abundant starting materials. Despite tremendous advances in OSC power conversion efficiency (PCE) over the last decade, active layer material selection and optimization is still largely empirical. In order...
Solid Oxide Fuel Cells (SOFCs) are a low-emission, efficient and fuel flexible energy conversion devices, which have been extensively applied in electricity generation systems. Moreover, it can also be operated in electrolysis mode as Solid Oxide Electrolysis Cell (SOEC) or Reversible Solid Oxide Cell (ReSOC) for intermittent renewable energy storage....
This dissertation consists of three essays in microeconomic theory. In the first two chapters, I study a class of partnerships where partners can exit and continue to free-ride on the remaining partners' efforts. The crucial force to deter players from strategic exiting is the ripple effect that it may trigger...
Manufacturing processes are known for their intricacies in changing material shapes and properties. New generations of manufacturing technologies, known as flexible manufacturing, are moving toward design freedom, which allows producing parts with optimized geometries and high customizations at an affordable cost even for low-volume productions. Two prominent flexible manufacturing processes...
Self-assembly of colloidal particles at the nano- and microscale has been a powerful tool for producing structures with emergent properties in applications ranging from electro-mechanical systems to photonics and biomedical devices. Great success has been achieved in experiments, where a variety of exotic phases have been discovered and even reconfigurable...
This dissertation analyzes how suburban school districts made sense of and planned to reduce inequality between 2019–2021. Previous literature has found that suburban schools, despite their reputation as the best in the country, are deeply unequal (Lewis and Diamond 2015; Lewis-McCoy 2014). Building on this previous scholarship, I ask: How...
