• (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.
• (Institute of Electrical and Electronics Engineers, 2011-02)
Transportation-On-Demand (TOD) systems, where users generate requests for transportation from a pick-up point to a delivery point, are already very popular and are expected to increase in usage dramatically as the inconvenience ...
• (IOP Publishing, 2013-04)
We have used asteroseismology to determine fundamental properties for 66 Kepler planet-candidate host stars, with typical uncertainties of 3% and 7% in radius and mass, respectively. The results include new asteroseismic ...
• (American Physical Society, 2009-06)
We demonstrate that the ratio of group to phase velocity has a simple relationship to the orientation of the electromagnetic field. In nondispersive materials, opposite group and phase velocity corresponds to fields that ...
• (Society for Industrial and Applied Mathematics, 2010-03)
The Wright–Fisher equation, which was introduced as a model to study demography in the presence of diffusion, has had a renaissance as a model for the migration of alleles in the genome. Our goal in this paper is to give ...
• (American Chemical Society, 2010-04)
Addition of ethylene to Mo(NAr)(CHCMe2Ph)(OHIPT)(Pyr) (NAr = N-2,6-i-Pr2C6H3, OHIPT = O-2,6-(2,4,6-i-Pr3C6H2)2C6H3, Pyr = NC4H4) led to the trigonal-bipyramidal metallacyclobutane complex Mo(NAr)(C3H6)(OHIPT)(Pyr), in which ...
• (University of Chicago Press, 2012-03)
This paper examines argues that while two distinct perspectives characterize the foundations of the public funding of research – filling a selection gap and solving a disclosure problem – in fact both the selection choices ...
• (National Academy of Sciences (U.S.), 2011-08)
Dectin-1, the major β-glucan receptor in leukocytes, triggers an effective immune response upon fungal recognition. Here we use sortase-mediated transpeptidation, a technique that allows placement of a variety of probes ...
• (Elsevier B.V., 2009-11)
Regulatory divergence is likely a major driving force in evolution. Comparative genomics is being increasingly used to infer the evolution of gene regulation. Ascomycota fungi are uniquely suited among eukaryotes for ...
• (Springer-Verlag, 2014)
Over the past decade, we have designed five typefaces based on mathematical theorems and open problems, specifically computational geometry. These typefaces expose the general public in a unique way to intriguing results ...
• (IOP Publishing, 2009-11)
The low-mass X-ray binary 4U 2129+47 was discovered during a previous X-ray outburst phase and was classified as an accretion disk corona source. A 1% delay between two mid-eclipse epochs measured ~22 days apart was reported ...
