Flaw-tolerance in silk fibrils explains strength, extensibility and toughness of spider silk
(American Chemical Society, 2011-10)Silk is an exceptionally strong, extensible, and tough material made from simple protein building blocks. The molecular structure of dragline spider silk repeat units consists of semiamorphous and nanocrystalline β-sheet ... -
FLEAT: A Multiscale Observational and Modeling Program to Understand How Topography Affects Flows in the Western North Pacific
(The Oceanography Society, 2019-12)Using a combination of models and observations, the US Office of Naval Research Flow Encountering Abrupt Topography (FLEAT) initiative examines how island chains and submerged ridges affect open ocean current systems, from ... -
FlexBoard: A Flexible Breadboard for Interaction Prototyping on Curved and Deformable Surfaces
(ACM|Proceedings of the 2023 CHI Conference on Human Factors in Computing Systems, 2023-04-19) -
The flexDrive: an ultra-light implant for optical control and highly parallel chronic recording of neuronal ensembles in freely moving mice
(Frontiers Research Foundation, 2013-05)Electrophysiological recordings from ensembles of neurons in behaving mice are a central tool in the study of neural circuits. Despite the widespread use of chronic electrophysiology, the precise positioning of recording ... -
FlexGP
(Springer Netherlands, 2014-11)We describe FlexGP, the first Genetic Programming system to perform symbolic regression on large-scale datasets on the cloud via massive data-parallel ensemble learning. FlexGP provides a decentralized, fault tolerant ... -
Flexibility and constraint: Evolutionary remodeling of the sporulation initiation pathway in Firmicutes
(Public Library of Science (PLoS), 2018-09)The evolution of signal transduction pathways is constrained by the requirements of signal fidelity, yet flexibility is necessary to allow pathway remodeling in response to environmental challenges. A detailed understanding ... -
Flexible and high-performance electrochromic devices enabled by self-assembled 2D TiO2/MXene heterostructures
(Springer Science and Business Media LLC, 2021)© 2021, The Author(s). Transition metal oxides (TMOs) are promising electrochromic (EC) materials for applications such as smart windows and displays, yet the challenge still exists to achieve good flexibility, high ... -
A flexible and robust neural network IASI-NH₃
(American Geophysical Union (AGU), 2016-06)n this paper, we describe a new flexible and robust NH₃ retrieval algorithm from measurements of the Infrared Atmospheric Sounding Interferometer (IASI). The method is based on the calculation of a spectral hyperspectral ... -
Flexible and stretchable nanowire-coated fibers for optoelectronic probing of spinal cord circuits
(American Association for the Advancement of Science (AAAS), 2017-03)Studies of neural pathways that contribute to loss and recovery of function following paralyzing spinal cord injury require devices for modulating and recording electrophysiological activity in specific neurons. These ... -
A flexible architecture and object-oriented model for space logistics simulation
(American Institute of Aeronautics and Astronautics, 2009-09)This paper summarizes the motivation for and the resulting development of a flexible object-oriented software model for simulation and analysis of space exploration campaign logistics. The software model was designed to ... -
Flexible Bureaucracies in Labor Market Regulation
(Oxford University Press, 2011-01)This paper compares and contrasts the U.S. and French systems of labor market regulation. The U.S. system is specialized: Regulating authority is dispersed among a host of different agencies each with a relatively narrow ... -
Flexible C : N ratio enhances metabolism of large phytoplankton when resource supply is intermittent
(Copernicus GmbH, 2014-09)Phytoplankton cell size influences particle sinking rate, food web interactions and biogeographical distributions. We present a model in which the uptake, storage and assimilation of nitrogen and carbon are explicitly ... -
A flexible ChIP-sequencing simulation toolkit
(BioMed Central, 2021-04-20)Abstract Background A major challenge in evaluating quantitative ChIP-seq analyses, such as peak calling and differential binding, is a lack of reliable ground truth data. ... -
A flexible cross-talk simulator for multiple spatial-mode free-space optical communication
(SPIE, 2014-10)Laser communication with both high photon information efficiency (many bits/detected-photon) and high spectral efficiency (many bits/sec-Hz) is impossible with a single spatial-mode free-space link. Achieving these high ... -
