• (Nature Publishing Group, 2012-10)
Evolutionary rewiring of regulatory networks is an important source of diversity among species. Previous evidence suggested substantial divergence of regulatory networks across species. However, systematically assessing ...
• (Springer-Verlag Berlin Heidelberg, 2014)
We introduce two new cryptographic primitives: functional digital signatures and functional pseudorandom functions. In a functional signature scheme, in addition to a master signing key that can be used to sign any ...
• (Royal Society of Chemistry, 2012-09)
Supported lipid bilayers are an important biomolecular tool for characterizing immunological synapses. Immobilized bilayers presenting tethered ligands on planar substrates have yielded both spatio-temporal and structural ...
• (Elsevier, 2011-01)
Ribosomes are highly conserved macromolecular machines that are responsible for protein synthesis in all living organisms. Work published in the past year has shown that changes to the ribosome core can affect the mechanism ...
• (National Academy of Sciences (U.S.), 2011-09)
Neuroscientists have debated for centuries whether some regions of the human brain are selectively engaged in specific high-level mental functions or whether, instead, cognition is implemented in multifunctional brain ...
• (National Academy of Sciences (U.S.), 2010-06)
Is the human mind/brain composed of a set of highly specialized components, each carrying out a specific aspect of human cognition, or is it more of a general-purpose device, in which each component participates in a wide ...
• (ASME International, 2014-08)
Design-by-analogy is a powerful approach to augment traditional concept generation methods by expanding the set of generated ideas using similarity relationships from solutions to analogous problems. While the concept of ...
• (Oxford University Press, 2009-05)
Making conclusions about the functional neuroanatomical organization of the human brain requires methods for relating the functional anatomy of an individual's brain to population variability. We have developed a method ...
• (American Chemical Society (ACS), 2013-05)
The class Ia ribonucleotide reductase (RNR) from Escherichia coli employs a free-radical mechanism, which involves bidirectional translocation of a radical equivalent or “hole” over a distance of ~35 Å from the stable ...
• (Rockefeller University Press, The, 2013-03)
Chromosome segregation requires the generation of force at the kinetochore—the multiprotein structure that facilitates attachment of chromosomes to spindle microtubules. This force is required both to move chromosomes and ...
• (Society for Industrial and Applied Mathematics, 2014-08)
When the heat equation and wave equation are approximated by $\bm{u}_t = -\bm{K} \bm{u}$ and $\bm{u}_{tt} = -\bm{K} \bm{u}$ (discrete in space), the solution operators involve $e^{-\bm{K}t}$, $\sqrt{\bm{K}}$, \$\cos(\sqrt ...
• (European Mathematical Society, 2010-01)
We associate to every monotone Lagrangian correspondence a functor between Donaldson–Fukaya categories. The composition of such functors agrees with the functor associated to the geometric composition of the correspondences, ...
• (National Academy of Sciences (U.S.), 2014-04)
Antarctic ozone depletion is associated with enhanced chlorine from anthropogenic chlorofluorocarbons and heterogeneous chemistry under cold conditions. The deep Antarctic “hole” contrasts with the generally weaker depletions ...
• (National Academy of Sciences (U.S.), 2013-04)
Throughout the plant and animal kingdoms specific cell types become polyploid, increasing their DNA content to attain a large cell size. In mammals, megakaryocytes (MKs) become polyploid before fragmenting into platelets. ...
• (Institute of Electrical and Electronics Engineers, 2010-09)
The availability of position information is of great importance in many commercial, public safety, and military applications. The coming years will see the emergence of location-aware networks with submeter accuracy, relying ...
• (Institute of Electrical and Electronics Engineers, 2010-09)
The availability of position information is of great importance in many commercial, governmental, and military applications. Localization is commonly accomplished through the use of radio communication between mobile devices ...
• (American Physical Society, 2014-03)
We show that there are shape-independent upper bounds to the extinction cross section per unit volume of dilute, randomly arranged nanoparticles, given only material permittivity. Underlying the limits are restrictive sum ...
• (American Physical Society, 2015-12)
Linear and nonlinear vibration energy harvesting has been the focus of considerable research in recent years. However, fundamental limits on the harvestable energy of a harvester subjected to an arbitrary excitation force ...
• (Optical Society of America, 2016-02)
At visible and infrared frequencies, metals show tantalizing promise for strong subwavelength resonances, but material loss typically dampens the response. We derive fundamental limits to the optical response of absorptive ...
• (Springer Berlin/Heidelberg, 2009)
Low jitter 500-fs pulse trains at a fundamental repetition rate of 3.2 GHz, from an Erfiber laser with a saturable Bragg reflector. An increase in repetition rate of femtosecond fiberlasers by one order of magnitude.
