 | Hawkes, Kristen | A reappraisal of grandmothering and natural selection | Kachel et al. [1] conclude from simulations of their agent-based model that fitness benefits from helpful grandmothers do not select for increased longevity. We studied their assumptions and model, ran further simulations and found flaws that are fatal to their test. Here, we explain four problems a... | | 2011-01-01 |

 | Awasthi, Manu; Nellans, David W.; Sudan, Kshitij; Balasubramonian, Rajeev | ABP : predictor based management of DRAM row buffers | DRAM accesses are costly, especially in multicore systems. Future CMPs will run a mixed load of workloads/threads. Destructive interference at memory controller, spatio-temporal locality lost! DRAM row-buffer hits are least expensive, row-conflicts are most. Randomized memory access patterns re... | | 2010-10-06 |

 | Hawkes, Kristen | Affluent hunters? Some comments in light of the Alyawara case | Our 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 |

 | Gerig, Guido | Asymmetrical ventricular enlargement in Parkinsons Disease | Background-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.

 | Gerig, Guido | Automatic and robust computation of 3D medial models incorporating object variability | Abstract. 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 |

 | Gerig, Guido | Brain lesion segmentation through physical model estimation | Segmentations of brain lesions from Magnetic Resonance (MR) images is crucial for quantitative analysis of lesion populations in neuroimaging of neurological disorders. We propose a new method for segmenting lesions in brain MRI by inferring the underlying physical models for pathology. We use the r... | Magnetic resonance (MR) images; Neurological disorders; Diffusion tensor imaging (DTI). | 2008-01-01 |

 | Hawkes, Kristen | Evaluating grandmother effects | Women who have outlived child-bearing have long been described as post-reproductive. But contributions they make to the survival or fertility of their descendants enhance the reproduction of their genes. Consequently natural selection affects this characteristic stage of human life history. Grandmot... | Human life history; Historical demography; Human longevity | 2009-01-01 |

 | Gerig, Guido | Evaluation of brain MRI alignment with the Robust Hausdorff Distance Measures | We present a novel automated method for assessment of image alignment, applied to non-rigid registration of brain Magnetic Resonance Imaging data (MRI) for image-guided neurosurgery. We propose a number of robust modifications to the Hausdorff distance (HD) metric, and apply it to the edges recovere... | Magnetic resonance imaging (MRI) | 2008-01-01 |

 | Gerig, Guido | Fiber tract-oriented statistics for quantitative diffusion tensor MRI analysis | Diffusion 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 modeling | 2006-01-01 |

 | Hawkes, Kristen | The grandmother effect | Why 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 |

 | Hawkes, Kristen | Grandmother effects, heterogeneity, and the evolution of human aging: guidance from human-chimpanzee comparisons | In the first paper to present formal theory explaining that senescence is a consequence of natural selection, W. D. Hamilton concluded that human postmenopausal longevity results from the contributions of ancestral grandmothers to the reproduction of their relatives.

 | Hawkes, Kristen | Human actuarial aging increases faster when background death rates are lower: a consequence of differential heterogeneity? | Many analyses of human populations have found that age-specific mortality rates increase faster across most of adulthood when overall mortality levels decline. This contradicts the relationship often expected from Williams' classic hypothesis about the effects of natural selection on the evolution o... | Frailty; Gompertz; Mortality rate doubling times; Ricklefs' omega; Strehler-Mildvan correlations; Weibull | 2011-01-01 |

 | Hawkes, Kristen | Mortality and fertility rates in humans and chimpanzees: how within-species variation complicates cross-species comparisons | A grandmother hypothesis may explain why humans evolved greater longevity while continuing to end female fertility at about the same age as do the other great apes. With that grandmother hypothesis in mind, we sought to compare age-specific mortality and fertility rates between humans and chimpanzee... | | 2009-01-01 |
