Axionic Black Holes and an Aharonov-Bohm Effect for Strings
(American Physical Society, 1988) -
The Axis of Progression of Disease
(Libertas Academica, 2014)Starting with genetic or environmental perturbations, disease progression can involve a linear sequence of changes within individual cells. More often, however, a labyrinth of branching consequences emanates from the initial ... -
AXIS: Generating Explanations at Scale with Learnersourcing and Machine Learning
(2016)While explanations may help people learn by providing information about why an answer is correct, many problems on online platforms lack high-quality explanations. This paper presents AXIS (Adaptive eXplanation Improvement ... -
Azuchi Castle: Architectural Innovation and Political Legitimacy in Sixteenth-Century Japan
(2016-05-10)This study seeks to clarify the limits of knowledge regarding Azuchi Castle (Azuchi-jō) and, in turn, offers a multifaceted interpretation of its crowning glory―the six-story, lavishly decorated, timber-framed tower known ... -
B cell homeostasis and follicle confines are governed by fibroblastic reticular cells
(2014)Fibroblastic reticular cells (FRCs) are known to inhabit T cell-rich areas of lymphoid organs where they function to coordinate T cell and dendritic cell interactions. However, in vivo manipulation of FRCs has been limited ... -
B-MYB and FOXM1 drive cell division through cooperative regulation of cell cycle genes.
(2024-03-12)Transcription facilitates cell cycle division and progression as it orchestrates the timely expression of genes crucial for each cell cycle phase. Two waves of gene expression prime the cell for replication: the first wave ... -
Baby Universes and String Theory
(American Physical Society, 2006)The description of 4D BPS black holes in terms of branes wrapped on various cycles in a Calabi-Yau space gives us the opportunity to study various issues in quantum gravity in a definite way by means of the worldvolume ... -
Bacillus spores as building blocks for stimuli-responsive materials and nanogenerators
(Nature Publishing Group, 2014) -
Back to the Drawing Board: Ed Ruscha 1956 – 68
(2015-05-15)This dissertation considers Ed Ruscha’s work through the theoretical lens of tacit knowledge, thereby making the argument that the commercial artist’s drawing board, and the world that it embodies, constitutes the material ... -
Back to the future
(Elsevier BV, 2013) -
Background ozone over the United States in summer: Origin, trend, and contribution to pollution episodes
(Wiley-Blackwell, 2002)Observations indicate that ozone (O3) concentrations in surface air over the United States in summer contain a 20–45 ppbv background contribution, presumably reflecting transport from outside the North American boundary ... -
Backward Raising
(Wiley Blackwell (Blackwell Publishing), 2012)This paper documents and analyzes an instance of covert A-movement, specifically covert subject-to-subject raising, in the Northwest Caucasian language Adyghe. We argue that Adyghe has a subject-to-subject raising ... -
Bacteria activate sensory neurons that modulate pain and inflammation
(2013)Summary Nociceptor sensory neurons are specialized to detect potentially damaging stimuli, protecting the organism by initiating the sensation of pain and eliciting defensive behaviors. Bacterial infections produce pain ... -
Bacteria Pattern Spontaneously on Periodic Nanostructure Arrays
(American Chemical Society (ACS), 2010)Surface-associated bacteria typically form self-organizing communities called biofilms. Spatial segregation is important for various bacterial processes associated with cellular and community development. Here, we demonstrate ... -
Bacterial Approaches to the Recovery of Scarce Metals
(2015-05-05)Many of the scarcest metals are critical to future energy technologies. However, these metals often have limited supplies, and their current production and recycling methods are complicated and use toxic chemicals. In ... -
Bacterial biofilm shows persistent resistance to liquid wetting and gas penetration
(Proceedings of the National Academy of Sciences, 2010)Most of the world’s bacteria exist in robust, sessile communities known as biofilms, ubiquitously adherent to environmental surfaces from ocean floors to human teeth and notoriously resistant to antimicrobial agents. We ... -
The Bacterial Carbon-Fixing Organelle Is Formed by Shell Envelopment of Preassembled Cargo
(Public Library of Science, 2013)Background: Cyanobacteria play a significant role in the global carbon cycle. In Synechococcuselongatus, the carbon-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is concentrated into polyhedral, ... -
Bacterial Cell Wall Synthases Require Outer Membrane Lipoprotein Cofactors
(2012-09-12)To fortify their cytoplasmic membrane and protect it from osmotic rupture, most bacteria surround themselves with a peptidoglycan (PG) exoskeleton. The PG synthases that build this structure are called penicillin-binding ... -
Bacterial chemotaxis and the question of gain
(National Academy of Sciences, 2002)Chemoreceptors in Escherichia coli are coupled to the flagella by a labile phosphorylated intermediate, CheYsimilar toP. Its activity can be inferred from the rotational bias of flagellar motors, but motor response is ... -
Bacterial Coexistence Driven by Motility and Spatial Competition
(Springer Science and Business Media LLC, 2020-02)Elucidating elementary mechanisms that underlie bacterial diversity is central to ecology and microbiome research. Bacteria are known to coexist by metabolic specialization, cooperation, and cyclic warfare. Many are also ...
