Bacterial terpene biosynthesis: Challenges and opportunities for pathway engineering
(Beilstein Institut, 2019-11)Terpenoids are the largest and structurally most diverse class of natural products. They possess potent and specific biological activity in multiple assays and against diseases, including cancer and malaria as notable ... -
A Bacterial Toxin Inhibits DNA Replication Elongation through a Direct Interaction with the β Sliding Clamp
(Elsevier, 2013-11)Toxin-antitoxin (TA) systems are ubiquitous on bacterial chromosomes, yet the mechanisms regulating their activity and the molecular targets of toxins remain incompletely defined. Here, we identify SocAB, an atypical TA ... -
Bacterial Vesicles in Marine Ecosystems
(American Association for the Advancement of Science (AAAS), 2014-01)Many heterotrophic bacteria are known to release extracellular vesicles, facilitating interactions between cells and their environment from a distance. Vesicle production has not been described in photoautotrophs, however, ... -
Bactericidal Antibiotics Induce Toxic Metabolic Perturbations that Lead to Cellular Damage
(Elsevier, 2015-10)Understanding how antibiotics impact bacterial metabolism may provide insight into their mechanisms of action and could lead to enhanced therapeutic methodologies. Here, we profiled the metabolome of Escherichia coli after ... -
Bacteriohopanepolyols along redox gradients in the Humboldt Current System off northern Chile
(Wiley, 2017-08)Marine oxygen minimum zones (OMZs) are characterized by the presence of subsurface suboxic or anoxic waters where diverse microbial processes are responsible for the removal of fixed nitrogen. OMZs have expanded over past ... -
Bacteriophage-based synthetic biology for the study of infectious diseases
(Elsevier, 2014-06)Since their discovery, bacteriophages have contributed enormously to our understanding of molecular biology as model systems. Furthermore, bacteriophages have provided many tools that have advanced the fields of genetic ... -
Bad data suppression in state estimation, with applications to problems in power.
(Massachusetts Institute of Technology, 1972) -
Baffle material characterization for Advanced LIGO
(Massachusetts Institute of Technology, 2008)The transition to Advanced LIGO introduces new sensitivity requirements for the LIGO interferometers. When light scatters away from the main laser beam, then scatters off the beam tube and returns to the main beam, noise ... -
Bagasse particle board: a production study and investment analysis.
(Massachusetts Institute of Technology, 1972) -
bagging
(Massachusetts Institute of Technology, 2020)The projective gesture of architecture, its forward reach as an offering, anticipates a recipient. Through a systematized catcall, it interpellates a subject as the beneficiary of its offering. As Mabel Wilson has reminded ... -
Bagging Regularizes
(2002-03-01)Intuitively, we expect that averaging --- or bagging --- different regressors with low correlation should smooth their behavior and be somewhat similar to regularization. In this note we make this intuition precise. ... -
Bahrain's competitiveness in the aluminum industry
(Massachusetts Institute of Technology, 1994) -
Bail bondsmen.

Baiting for defense against stealthy attacks on cyber-physical systems
(Massachusetts Institute of Technology, 2019)The goal of this thesis is to develop a defense methodology for a cyber-physical system (CPS) by which an attempted stealthy cyber-attack is detected in near real time. Improvements in networked communication have enabled ... -
Baker Vs. Carr in Context

A Bakery : in search of appropriate form
(Massachusetts Institute of Technology, 1982)During the process of designing a building there occurs the continuous task of finding the forms, materials and structure that are fit to the particular building or situation at hand. It is the intent to combine these ... -
Balance : Lancaster County's tragedy
(Massachusetts Institute of Technology, 2007)Lancaster County, Pennsylvania residents are proud of their agricultural heritage. They do not want to see their farmland disappear. But the County continues to be developed into residential subdivisions. This thesis ... -
The Balance Between Preventing Fraud and Ensuring Participation: Attitudes Towards Voter Identification in New Mexico
(Caltech/MIT Voting Technology Project, 2011-07)This paper examines public opinion on the effectiveness and consequences of voter identification laws in New Mexico. In particular, it focuses on the attitudes central to the court reasoning in the 2008 Supreme Court case ...
