- Description:
- 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...

- Description:
- 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...

- Description:
- 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...

- Description:
- 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...

- Description:
- 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...

- Description:
- 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...

- Description:
- The field of materials discovery is undergoing an unprecedented transition from laboratory tocomputer. Behind this transition is the new ability to accurately compute material properties, especially energetic stability, from first principles with density functional theory (DFT). However, DFT remains computationally expensive, and DFT-based materials discovery is intractable, especially in high...

- Description:
- One method of cancer treatment is to thermally ablate (destroy) tumor masses using heat caused by electric current, or Joule heating. This particular modality is called radiofrequency ablation (RFA), due to the use of electric currents in the 100 kHz to 800 kHz frequency range. Computationally, RFA is simulated as...

- Description:
- As sound changes advance across large geographic areas, they progress unevenly across populations. The speakers who lead these changes often share macro-social identities, like place or social class affiliations (e.g. Nesbitt 2018; Wagner et al. 2016). But the features undergoing these macro-level sound changes also hold social meanings related to...

- We consider general utility models and information structures of the agents and illustrate when economic conclusions for designing simple mechanisms in classical settings extends for general environments. We show that whether economic conclusions can be generalized depends on the details of the generalizations. For example, in single-item auction, competition and...
