Filtering of Milankovitch Cycles by Earth's Geography
Abstract Earth's land-sea distribution modifies the temperature response to orbitally induced perturbations of the seasonal insolation. We examine this modification in the frequ...

Mobile Robot Localization and Mapping with Uncertainty using Scale-Invariant Visual Landmarks
A key component of a mobile robot system is the ability to localize itself accurately and, simultaneously, to build a map of the environment. Most of the existing algorithms are...
Numerical operator calculus in higher dimensions
When an algorithm in dimension one is extended to dimension d , in nearly every case its computational cost is taken to the power d . This fundamental difficulty is the single g...
The Discovery of a Luminous [CLC][ITAL]z[/ITAL][/CLC] = 5.80 Quasar from the Sloan Digital Sky Survey
We present observations of SDSSp J104433.04--012502.2, a luminous quasar at z=5.80 discovered from Sloan Digital Sky Survey (SDSS) multicolor imaging data. This object was selec...
Should substance use disorders be considered as categorical or dimensional?
ABSTRACT Aims This paper discusses the representation of diagnostic criteria using categorical and dimensional statistical models. Conventional modeling using categorical or con...
Molecular Similarity Searching Using Atom Environments, Information-Based Feature Selection, and a Naïve Bayesian Classifier
A novel technique for similarity searching is introduced. Molecules are represented by atom environments, which are fed into an information-gain-based feature selection. A naïve...
A Three-Dimensional Edge Operator
Modern scanning techniques, such as computed tomography, have begun to produce true three-dimensional imagery of internal structures. The first stage in finding structure in the...
Low-dimensional representation of faces in higher dimensions of the face space
Faces can be represented efficiently as a weighted linear combination of the eigenvectors of a covariance matrix of face images. It has also been shown [ J. Opt. Soc. Am.4, 519–...
On the nature of antibody combining sites: Unusual structural features that may confer on these sites an enhanced capacity for binding ligands
Abstract A detailed analysis of the structural aspects of antibody–antigen interactions has been made possible by the availability of X‐ray structures for three complexes of ant...
Improved time bounds for near-optimal sparse Fourier representations
•We study the problem of finding a Fourier representation <b>R </b>of <i>m</i> terms for a given discrete signal <b>A</b> of length<i> N</i>. The Fast Fourier Transform (FFT) ca...
Imagery and posttraumatic stress disorder: an overview
A review of theories of traumatic neurosis or posttraumatic stress disorder reveals a relative neglect of the role of posttraumatic imagery. The broad range of imagery has not b...
