Fixed frequency eigenfunction immersions and supremum norms of random waves
(American Institute of Mathematical Sciences (AIMS), 2015-08)A compact Riemannian manifold may be immersed into Euclidean space by using high frequency Laplace eigenfunctions. We study the geometry of the manifold viewed as a metric space endowed with the distance function from the ... -
Fixed-point adiabatic quantum search
(American Physical Society, 2017-01)Fixed-point quantum search algorithms succeed at finding one of M target items among N total items even when the run time of the algorithm is longer than necessary. While the famous Grover's algorithm can search quadratically ... -
Fixed-Point Quantum Search with an Optimal Number of Queries
(American Physical Society, 2014-11)Grover’s quantum search and its generalization, quantum amplitude amplification, provide a quadratic advantage over classical algorithms for a diverse set of tasks but are tricky to use without knowing beforehand what ... -
Fixin' to Divide
(Elsevier, 2012-02)In this issue of Molecular Cell, Yata et al. (2012) show that the mitotic kinase and cell-cycle regulator Plk1 can directly stimulate the DNA repair process, providing a potential mechanism of crosstalk between DNA repair ... -
Fixing Malfunctional Objects With Learned Physical Simulation and Functional Prediction

Fixing nature’s carbon inefficiencies
(Elsevier BV, 2021-04)Conversion of C₂ to C₃ compounds is used by nature in abundant processes such as photorespiration but comes at the cost of CO₂ release. Erb and co-workers recently published an article in Nature Catalysis describing a ... -
Fizeau drag in graphene plasmonics
(Springer Science and Business Media LLC, 2021)Dragging of light by moving dielectrics was predicted by Fresnel and verified by Fizeau's celebrated experiments with flowing water. This momentous discovery is among the experimental cornerstones of Einstein's special ... -
FK COMAE BERENICES, KING OF SPIN: THE COCOA-PUFS PROJECT
(IOP Publishing, 2016-03)COCOA-PUFS is an energy-diverse, time-domain study of the ultra-fast spinning, heavily spotted, yellow giant FK Comae Berenices (FK Com: HD117555; G4 III). This single star is thought to be a recent binary merger, and is ... -
Flag Hilbert schemes, colored projectors and Khovanov-Rozansky homology
(Elsevier BV, 2021)We construct a categorification of the maximal commutative subalgebra of the type A Hecke algebra. Specifically, we propose a monoidal functor from the (symmetric) monoidal category of coherent sheaves on the flag Hilbert ... -
The flag manifold over the semifield Z

Flagellar synchronization through direct hydrodynamic interactions
(eLife Sciences Publications, Ltd, 2014-07)Flows generated by ensembles of flagella are crucial to development, motility and sensing, but the mechanisms behind this striking coordination remain unclear. We present novel experiments in which two micropipette-held ... -
Flagellar waveform dynamics of freely swimming algal cells
(American Physical Society, 2013-07)We present quantitative measurements of time-dependent flagellar waveforms for freely swimming biflagellated algal cells, for both synchronous and asynchronous beating. We use the waveforms in conjunction with resistive ... -
A FLARE IN THE JET OF PICTOR A
(Institute of Physics/American Astronomical Society, 2010-05)A Chandra X-ray imaging observation of the jet in Pictor A showed a feature that appears to be a flare that faded between 2000 and 2002. The feature was not detected in a follow-up observation in 2009. The jet itself is ... -
Flares, Rotation, and Planets of the AU Mic System from TESS Observations
(American Astronomical Society, 2022)<jats:title>Abstract</jats:title> <jats:p>AU Mic is a young (∼24 Myr), pre-main-sequence M dwarf star that was observed in the first month of science observations of the Transiting Exoplanet Survey Satellite ... -
Flat entanglement spectra in fixed-area states of quantum gravity
(Springer Berlin Heidelberg, 2019-10-24)Abstract We use the Einstein-Hilbert gravitational path integral to investigate gravita- tional entanglement at leading order O(1/G). We argue that semiclassical states prepared by a ... -
Flat Foldings of Plane Graphs with Prescribed Angles and Edge Lengths
(Springer-Verlag, 2014)When can a plane graph with prescribed edge lengths and prescribed angles (from among {0,180°, 360°}) be folded flat to lie in an infinitesimally thick line, without crossings? This problem generalizes the classic theory ... -
Flat photonic surface bands pinned between Dirac points
(Optical Society of America, 2012-12)We point out that 2D photonic crystals (PhCs) can support surface bands that are pinned to Dirac points. These bands can be made very flat by optimizing the parameters of the system. Surface modes are found at the interface ... -
Flat vs. Expressive Storytelling: Young Children’s Learning and Retention of a Social Robot’s Narrative
(Frontiers Research Foundation, 2017-06)Prior research with preschool children has established that dialogic or active book reading is an effective method for expanding young children’s vocabulary. In this exploratory study, we asked whether similar benefits are ... -
Flat-top oscillons in an expanding universe
(American Physical Society, 2010-04)Oscillons are extremely long lived, oscillatory, spatially localized field configurations that arise from generic initial conditions in a large number of nonlinear field theories. With an eye towards their cosmological ... -
