1 Hawkes, KristenAffluent hunters? Some comments in light of the Alyawara caseOur recent analysis (O'Connell and Hawkes in press) of plant food collecting among the Alyawara, a central Australian hunting group, shows that the cost of subsistence is sometimes quite high, far higher than the current conven. tional wisdom regarding hunters would suggest. We infer from available ...1981-01-01

3 Gerig, GuidoAsymmetrical ventricular enlargement in Parkinsons DiseaseBackground-A recent case report suggested the presence of asymmetrical lateral ventricular enlargement associated with motor asymmetry in Parkinson's disease (PD). The current study explored these associations further. Methods-Magnetic resonance imaging (3T) scans were obtained on 17 PD and 15 healt...Structural magnetic resonance imaging; Semi-automatic segmentation; Lateral ventricular volume; Motor asymmetry; Parkinson's disease2007-01-01
4 Gerig, GuidoAutomatic and robust computation of 3D medial models incorporating object variabilityAbstract. This paper presents a novel processing scheme for the automatic and robust computation of a medial shape model which represents an object population with shape variability. The sensitivity of medial descriptions to object variations and small boundary perturbations are fundamental problems...2003-01-01
5 Arlitsch, KenningCollaboration and partnerships: opportunities aboundPowerPoint presentation describing some of the digital collection building partnerships of the University of Utah. Major covered projects include the Utah Digital Newspapers Program, Mountain West Digital Library, Western Waters Digital Library, and the Utah Artists Project, among others.Digital collections; Electronic libraries; Cooperative collection building2006-01-22
6 Gerig, GuidoFiber tract-oriented statistics for quantitative diffusion tensor MRI analysisDiffusion tensor imaging (DTI) has become the major modality to study properties of white matter and the geometry of fiber tracts of the human brain. Clinical studies mostly focus on regional statistics of fractional anisotropy (FA) and mean diffusivity (MD) derived from tensors. Existing analysis t...Diffusion tensor interpolation, Diffusion tensor statistics, DTI analysis, Fiber tract modeling2006-01-01
7 Hawkes, KristenThe grandmother effectWhy do women live long past the age of child-bearing? Contrary to common wisdom, this phenomenon is not new, and is not due to support for the elderly. Rather, grannies have a lot to offer their grandchildren.2004-01-01
8 Dennis, Sharon E.; Uijtdehaage, Sebastian; Candler, C.Health Education Assets Library (HEAL)The Health Education Assets Library (HEAL) is a digital library that provides freely accessible digital teaching resources of the highest quality that meet the needs of today's health sciences educators and learners.HEAL; Health Education Assets Library2000
9 Gerig, GuidoHypothesis testing with nonlinear shape modelsWe present a method for two-sample hypothesis testing for statistical shape analysis using nonlinear shape models. Our approach uses a true multivariate permutation test that is invariant to the scale of different model parameters and that explicitly accounts for the dependencies between variables. ...2005-01-01
10 Hawkes, KristenKin selection and cultureThis paper argues that while the discriminations organizing human action are cultural, and kinship in anthropology is not equivalent to genetic relatedness, the theory of kin selection developed in evolutionary biology can tell us a great deal about human social organization. Data on garden assistan...1983-01-01

12 Gerig, GuidoObject models in multiscale intrinsic coordinates via m-repsObject descriptions used for 3D segmentation by deformable models and for statistical characterization of 3D object classes benefit from having intrinsic correspondences over deformation of the objects or multiple instances in the same object class. These correspondences apply over a variety of spat...2003-01-01
13 Gerig, GuidoProbabilistic fiber tracking using particle filteringThis paper presents a novel and fast probabilistic method for white matter fiber tracking from diffusion weighted MRI (DWI). We formulate fiber tracking on a nonlinear state space model which is able to capture both smoothness regularity of fibers and uncertainties of the local fiber orientations du...2007-01-01
14 Gerig, GuidoQuantification of measurement error in DTI: theoretical predictions and validationThe presence of Rician noise in magnetic resonance imaging (MRI) introduces systematic errors in diffusion tensor imaging (DTI) measurements. This paper evaluates gradient direction schemes and tensor estimation routines to determine how to achieve the maximum accuracy and precision of tensor derive...2007-01-01
15 Gerig, GuidoUnbiased atlas formation via large deformations metric mappingThe construction of population atlases is a key issue in medical image analysis, and particularly in brain mapping. Large sets of images are mapped into a common coordinate system to study intrapopulation variability and inter-population differences, to provide voxelwise mapping of functional sites,...Computational anatomy; Brain atlases; Image metric space2005-01-01
16 Gerig, GuidoUser-guided 3D active contour segmentation of anatomical structures: significantly improved efficiency and reliabilityActive contour segmentation and its robust implementation using level set methods are well-established theoretical approaches that have been studied thoroughly in the image analysis literature. Despite the existence of these powerful segmentation methods, the needs of clinical research continue to b...Computational anatomy; Image segmentation; Caudate nucleus; 3D active contour models; Open source software; Validation; Anatomical objects2006-01-01
17 Gerig, GuidoVessel tortuosity and brain tumor malignancy: a blinded studyRationale-Malignancy provokes regional changes to vessel shape. Characteristic vessel tortuosity abnormalities appear early during tumor development, affect initially healthy vessels, spread beyond the confines of tumor margins, and do not simply mirror tissue perfusion. The ability to detect and qu...Computer; Cancer; Blood vessels; Tortuosity; MRA; Brain tumor2005-01-01
