Physicists at Boston University look to open a window on the universe. An understanding of physics can elucidate everything from how a ball falls to the ground to what the early universe looked like, can shed light on the forces guiding the cosmos and the behavior of subatomic particles. A degree in physics provides the intellectual foundation for applications in engineering, technology, and industry, as well as in training the next generation of scientists at both the high school and university levels.

Flux imbalance analysis and the sensitivity of cellular growth to changes in metabolite pools
(Public Library of Science, 2013)Stoichiometric models of metabolism, such as flux balance analysis (FBA), are classically applied to predicting steady state rates - or fluxes - of metabolic reactions in genome-scale metabolic networks. Here we revisit ... -
Signatures of arithmetic simplicity in metabolic network architecture
(PUBLIC LIBRARY OF SCIENCE, 2010-04-01)Metabolic networks perform some of the most fundamental functions in living cells, including energy transduction and building block biosynthesis. While these are the best characterized networks in living systems, understanding ... -
Monolayer MoS2 strained to 1.3% with a microelectromechanical system
(Institute of Electrical and Electronics Engineers (IEEE), 2019-04)We report on a modified transfer technique for atomically thin materials integrated onto microelectromechanical systems (MEMS) for studying strain physics and creating strain-based devices. Our method tolerates the ... -
The mesoscopic magnetron as an open quantum system
(2016-02-24)Motivated by the emergence of materials with mean free paths on the order of microns, we propose a novel class of solid state radiation sources based on reimplementing classical vacuum tube designs in semiconductors. Using ... -
Cohesiveness in financial news and its relation to market volatility
(NATURE PUBLISHING GROUP, 2014-05-22)Motivated by recent financial crises, significant research efforts have been put into studying contagion effects and herding behaviour in financial markets. Much less has been said regarding the influence of financial news ... -
Cascading failures in bi-partite graphs: model for systemic risk propagation
(NATURE PUBLISHING GROUP, 2013-02-05)As economic entities become increasingly interconnected, a shock in a financial network can provoke significant cascading failures throughout the system. To study the systemic risk of financial systems, we create a bi-partite ... -
Partial correlation analysis: applications for financial markets
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2015-04-03)The presence of significant cross-correlations between the synchronous time evolution of a pair of equity returns is a well-known empirical fact. The Pearson correlation is commonly used to indicate the level of similarity ... -
Confidence and self-attribution bias in an artificial stock market
(PUBLIC LIBRARY SCIENCE, 2017-02-23)Using an agent-based model we examine the dynamics of stock price fluctuations and their rates of return in an artificial financial market composed of fundamentalist and chartist agents with and without confidence. We find ... -
Multiple tipping points and optimal repairing in interacting networks
(NATURE PUBLISHING GROUP, 2016-03-01)Systems composed of many interacting dynamical networks—such as the human body with its biological networks or the global economic network consisting of regional clusters—often exhibit complicated collective dynamics. Three ... -
Transverse spin diffusion in a dilute spin-polarized degenerate Fermi gas
(SPRINGER/PLENUM PUBLISHERS, 1998-08-01)We re-examine the calculation of the transverse spin-diffusion coefficient in a dilute degenerate spin-polarized Fermi gas, for the case of s-wave scattering. The special feature of this limit is that the dependence of the ...
