A theory of sustained cooperation with evidence from irrigation institutions in Nepal
(Massachusetts Institute of Technology, 2014)
Why do some locally based institutions for using and managing shared resources survive, adapt and continue to perform well in the face of changing circumstances while others decline and disappear? To answer this, I revisited ...
Essays in financial economics
(Massachusetts Institute of Technology, 2018)
The essays in this thesis study issues in finance affecting large corporations, developing economies, and households. The common theme that connects these essays is a focus on how financial institutions, frictions, and ...
Fast in-memory storage systems : two aspects
(Massachusetts Institute of Technology, 2014)
This dissertation addresses two challenges relating to in-memory storage systems. The first challenge is storing and retrieving data at a rate close to the capabilities of the underlying memory system, particularly in the ...
Electronic structure of perovskite oxide surfaces at elevated temperatures and its correlation with oxygen reduction reactivity
(Massachusetts Institute of Technology, 2014)
The objective is to understand the origin of the local oxygen reduction reaction (ORR) activity on the basis of the local electronic structure at the surface of transition metal oxides at elevated temperatures and in oxygen ...
Inflammation triggers Zeb1-dependent escape from tumor dormancy
(Massachusetts Institute of Technology, 2016)
Metastasis-related mortality for breast cancer patients often occurs many years after treatment of the primary tumor. Inflammation, through the orchestra of immune cells and released inflammatory cytokines, can predispose ...
Biological and bio-inspired morphometry as a route to tunable and enhanced materials design
(Massachusetts Institute of Technology, 2016)
Structural materials in nature integrate classical materials selection rules with morphometry (geometry or shape-based rules) to create high-performance, multi-functional structures that exhibit tunable properties through ...
Toxin-antitoxin systems in bacteria : targets, mechanisms, and specificity
(Massachusetts Institute of Technology, 2015)
Toxin-antitoxin (TA) systems are genetic modules widely present on bacterial chromosomes. These systems comprise a toxin and cognate antitoxin that are encoded together in an operon; normally, the toxin and antitoxin are ...
The role of control information in wireless link scheduling
(Massachusetts Institute of Technology, 2015)
In wireless networks, transmissions must be scheduled to opportunistically exploit the time-varying capacity of the wireless channels to achieve maximum throughput. These opportunistic policies require global knowledge of ...
Harmonic poly-actuator : design and control of a new piezoelectric mechanism
(Massachusetts Institute of Technology, 2015)
Piezoelectric devices, e.g. piezoelectric stack actuators, have several salient features inherent to their structure. They are efficient, have a high bandwidth, and their capacitive loading allows for static loads to be ...
Nonlinear optical and photoemission spectroscopies of quantum materials
(Massachusetts Institute of Technology, 2018)
Quantum materials are characterized by a macroscopic behavior that does not have a clear classical counterpart. Among the experimental probes capable of exploring the exotic properties of quantum materials, ultrafast laser ...
