• (MIT Press, 2010-10)
The metrization of the space of neural responses is an ongoing research program seeking to find natural ways to describe, in geometrical terms, the sets of possible activities in the brain. One component of this program ...
• (American Physical Society, 2013-02)
We develop and demonstrate an acceleration of the Liu and Tegmark quadratic estimator formalism for inverse variance foreground subtraction and power spectrum estimation in 21 cm tomography from O(N[superscript 3]) to ...
• (Society for Industrial and Applied Mathematics, 2011-06)
The $p$-radius characterizes the average rate of growth of norms of matrices in a multiplicative semigroup. This quantity has found several applications in recent years. We raise the question of its computability. We prove ...
• (American Society for Cell Biology, 2010-01)
Metaphase spindles are steady-state ensembles of microtubules that turn over rapidly and slide poleward in some systems. Since the discovery of dynamic instability in the mid-1980s, models for spindle morphogenesis have ...
• (Nature Publishing Group, 2013-10)
The basal forebrain provides the primary source of cholinergic input to the cortex, and it has a crucial function in promoting wakefulness and arousal. However, whether rapid changes in basal forebrain neuron spiking in ...
• (Springer-Verlag, 2015-06)
Increasing the dimensionality of NMR experiments strongly enhances the spectral resolution and provides invaluable direct information about atomic interactions. However, the price tag is high: long measurement times and ...
• (Association for Computing Machinery, 2014-08)
An ideal datacenter network should provide several properties, including low median and tail latency, high utilization (throughput), fair allocation of network resources between users or applications, deadline-aware ...
• (Society for Industrial and Applied Mathematics, 2011-12)
We obtain randomized algorithms for factoring degree n univariate polynomials over $\mathbb{F}_q$ requiring $O(n^{1.5 + o(1)}\,{\rm log}^{1+o(1)} q+ n^{1 + o(1)}\,{\rm log}^{2+o(1)} q)$ bit operations. When \${\rm log}\, q ...
• (BioMed Central Ltd, 2014-08)
Background High-throughput next generation sequencing technologies have enabled rapid characterization of clinical and environmental samples. Consequently, the largest bottleneck to actionable data has become sample ...
• (Wiley Blackwell, 2013-11)
Purpose To enable fast reconstruction of quantitative susceptibility maps with total variation penalty and automatic regularization parameter selection. Methods ℓ[subscript 1]-Regularized susceptibility mapping is ...
• (Institute of Electrical and Electronics Engineers (IEEE), 2010-12)
Optical Flow Switching (OFS) is a promising architecture to provide end users with large transactions with cost-effective direct access to core network bandwidth. For very dynamic sessions that are bursty and only last a ...
• (Institute of Electrical and Electronics Engineers (IEEE), 2013-07)
We propose a novel algorithm for selection of dangerous N-2 contingencies associated with line or generator failures. The algorithm is based on iterative filtering of the set of all possible double contingencies. It is ...
• (Institute of Electrical and Electronics Engineers, 2009-12)
This paper presents shadow detection methods for vision-based autonomous driving in an urban environment. Shadows misclassified as objects create problems in autonomous driving applications. Real-time efficient algorithms ...
• (Institute of Electrical and Electronics Engineers (IEEE), 2014-10)
A fast numerical method is presented for the simulation of complicated 3-D structures, such as inductors constructed from Litz or stranded wires, above or sandwiched between the planar lossy magnetic media. Making use of ...
• (Elsevier, 2010-01)
We develop a multiscale simulation method for dense granular drainage, based on the recently proposed spot model, where the particle packing flows by local collective displacements in response to diffusing “spots” of ...
• (International Speech Communication Association, 2009-09)
We introduce a new method for human-machine collaborative speech transcription that is significantly faster than existing transcription methods. In this approach, automatic audio processing algorithms are used to robustly ...
• (National Academy of Sciences (U.S.), 2010-06)
It is unusual for both A and A[superscript -1] to be banded—but this can be a valuable property in applications. Block-diagonal matrices F are the simplest examples; wavelet transforms are more subtle. We show that every ...
• (IOP Publishing, 2015-10)
We explore the variability properties of long, high-cadence general relativistic magnetohydrodynamic (GRMHD) simulations across the electromagnetic spectrum using an efficient, GPU-based radiative transfer algorithm. We ...
• (American Mathematical Society (AMS), 2012-02)
This paper presents a numerical method for time upscaling'' wave equations, i.e., performing time steps not limited by the Courant-Friedrichs-Lewy (CFL) condition. The proposed method leverages recent work on fast ...
• (Public Library of Science, 2013-03)
Species expand their geographical ranges following an environmental change, long range dispersal, or a new adaptation. Range expansions not only bring an ecological change, but also affect the evolution of the expanding ...
