Prediction of CsrA-regulating small RNAs in bacteria and their experimental verification in Vibrio fischeri
The role of small RNAs as critical components of global regulatory networks has been highlighted by several recent studies. An important class of such small RNAs is represented by CsrB and CsrC of Escherichia coli, which ...
The Natural Statistics of Audiovisual Speech
Humans, like other animals, are exposed to a continuous stream of signals, which are dynamic, multimodal, extended, and time varying in nature. This complex input space must be transduced and sampled by our sensory systems ...
Breathing dynamics in heteropolymer DNA
(CELL PRESS, 2007-04)
While the statistical mechanical description of DNA has a long tradition, renewed interest in DNA melting from a physics perspective is nourished by measurements of the fluctuation dynamics of local denaturation bubbles ...
Leptonic CP violation search and the ambiguity of delta m(31)(2)
(American Physical Society, 2006-03)
We consider a search for the CP-violating angle delta(CP) in long baseline neutrino oscillation experiments. We show that the subleading delta(CP)-dependent terms in the nu(mu)->nu(e) oscillation probability can be easily ...
Thermal production of axions in the Earth
(American Physical Society, 2009-05)
We estimate the production rate of axion-type particles in the core of the Earth, at a temperature T approximate to 5000 K. We constrain thermal geo-axion emission by demanding a core-cooling rate less than O(100) K/Gyr, ...
Multiple regime shifts in a subtropical peatland: community-specific thresholds to eutrophication
(Ecological Society of America, 2008-11)
Ecosystems have a natural resilience to perturbations, where resilience is the magnitude of a disturbance that an ecosystem can resist before changes in structure, function, and services result in a regime shift. The ...
Patterns in soil fertility and root herbivory interact to influence fine-root dynamics
(Ecological Society of America, 2006-03)
Fine-scale soil nutrient enrichment typically stimulates root growth, but it may also increase root herbivory, resulting in trade-offs for plant species and potentially influencing carbon cycling patterns. We used root ...
A Model to Predict the Impact of Specification Changes on Chloride-Induced Corrosion Service Life of Virginia Bridge Decks
(Virginia Center for Transportation Innovation and Research, 2002-10)
A model to determine the time to first repair and subsequent rehabilitation of concrete bridge decks exposed to chloride deicer salts that recognizes and incorporates the statistical nature of factors affecting the corrosion ...
LISA: Laboratory for Interdisciplinary Statistical Analysis Annual Report 2008-2009
This report documents LISA's activities for the 2008-2009 academic year.
Processing of emotional faces in children and adolescents with anxiety disorders
(Cambridge University Press, 2007-11)
The purpose of this study was to test whether children and adolescents with anxiety disorders exhibit selective processing of threatening facial expressions in a pictorial version of the emotional Stroop paradigm. Participants ...
