Since the invitation of ARPANet in 1969, network protocols and communication systems have continued to emerge. Especially in the past decade, the prosperity of mobile internet and cloud computing has resulted in a large number of network protocols and communication systems, which have become critical infrastructure for our society.

In the first part of the thesis we,given a dg-Lie algebra $\g$, a commutative
dg-algebra $A$ and a twisting cochain $\mu$ in
$A \otimes \g$, we construct a map
from the functor of curved deformations of $\g$ to the
functor of curved deformations of the twisted tensor product
$A \otimes_\mu...
Although flowing granular materials have been formally studied for over two hundred years, their behavior is still poorly understood relative to fluids, solids, and gases. Sheared granular materials with differing particle properties (e.g., size, density, shape) segregate (de-mix) due to percolation (small particles fall between large ones) and buoyancy (light...
In this dissertation I leverage new data from the global music recording industry to study the social foundations of creativity and the relationship between product novelty, gender, and commercial success. In Chapter 1, I investigate how different kinds of social connection influence the creation of novel cultural products. Using data...
The role of mesoscale structure on the properties of functional materials is poorly understood as the influence of mesoscale structure is both complicated and material specific. Thus there is not only a lack of a general understanding of how structure influences emergent properties but also a lack of a general...
Security and robustness are two critical problems in modern computing system. In this disserta- tion, we study these two problems in both hardware system and learning system.Firstly, we discuss the robustness problem in hardware system. Modern microprocessors suffer from significant on-chip variation at the advanced technology nodes. The development of...
The objective of this dissertation is to examine the mutually constitutive relationship between historiography, collective memory, and cultural narratives in the representation of the Algerian War of Independence (1954–1962) in present-day France and Algeria. Taking the turn of the twenty-first century as its point of departure, this study analyzes modern...
Processing of sensory information in the brain is a pervasive and fundamental phenomenon across animal species and is involved in both "hard-wired" innate responses as well as learned and adaptive behaviors. Here, I show that the avoidance of hot temperature, a simple innate behavior, contains unexpected plasticity and complex processing...
Public-facing data-driven technologies such as social media platforms and search engines rely on data producers, such as users and crowd workers, to be feasible and financially sustainable. Recently, it became clear that the goals of these data-driven technologies do not always align with those of the public, causing public backlashes...
Respiratory-swallow coordination is implicated as an essential component of safe and efficient swallowing, yet current evidence is incomplete regarding its relevance to swallowing impairment, assessment and treatment. Three studies were conducted that: 1) characterized and confirmed the optimal respiratory-swallowing coordination patterns in healthy adults, 2) identified linkages between deviations in...
