The evaluator effect: a chilling fact about usability evaluation methods
- Int. Journal of Human-Computer Interaction
"... Computer professionals have a need for robust, easy-to-use usability evaluation methods (UEMs) to help them systematically improve the usability of computer artifacts. However, cognitive walkthrough (CW), heuristic evaluation (HE), and thinking- aloud study (TA)—3 of the most widely used UEMs—suffer ..."

—suffer from a substantial evaluator effect in that multiple evaluators evaluating the same interface with the same UEM detect markedly different sets of problems. Areview of 11 studies of these 3 UEMs reveals that the evaluator effect exists for both novice and experienced evaluators, for both cosmetic
Deadlock and Persistency Detection of Temporal Specifications
"... Every paper aught to have an abstract, however it's important that the author writes something of relevance to the documentation otherwise the abstract becomes meaningless. 1 Introduction T HE detection of potential errors within an asynchronous circuit is of fundamental importance. This is ..."

Persistent Homological Sparse Network Approach to Detecting White Matter Abnormality in Maltreated Children: MRI and DTI Multimodal Study
"... Abstract. We present a novel persistent homological sparse network analysis framework for characterizing white matter abnormalities in tensorbased morphometry (TBM) in magnetic resonance imaging (MRI). Traditionally TBM is used in quantifying tissue volume change in each voxel in a massive univariat ..."

univariate fashion. However, this obvious approach cannot be used in testing, for instance, if the change in one voxel is related to other voxels. To address this limitation of univariate-TBM, we propose a new persistent homological approach to testing more complex relational hypotheses across brain regions
Mobile Network Estimation
, 2001
"... Mobile systems must adapt their behavior to changing network conditions. To do this, they must accurately estimate available network capacity. Producing quality estimates is challenging because network observations are noisy, particularly in mobile, ad hoc networks. Current systems depend on simple, ..."

, exponentially-weighted moving average (EWMA) filters. These filters are either able to detect true changes quickly or to mask observed noise and transients, but cannot do both. In this paper, we present four filters designed to react quickly to persistent changes while tolerating transient noise. Such filters
Persistence of PCR-detectable Bacteroides distasonis from human feces
, 1998
"... To evaluate the persistence of PCR-detectable Bacteroides distasonis in surface water, whole human feces were dispersed into water from the Ohio River and incubated in flasks in the laboratory or in diffusion chambers in situ. Duplicate samples were taken daily, and material that pelleted at 16,000 ..."

SCAR: Dynamic adaptation for person detection and persistence analysis in unconstrained videos
"... Abstract. In many forensic and data analytics applications there is a need to detect whether and for how long a specific person is present in a video. Frames in which the person cannot be recognized by state of the art engines are of particular importance. We describe a new framework for detection a ..."

Persistent infection of human fibroblasts by hepatitis A virus
, 1984
"... Infection of human embryo fibroblasts with hepatitis A virus (HAV), a picornavirus, leads to an inapparent, persistent infection; cultures can be passed serially with consistent recovery of the virus in the supernatant. All of the cells of a HAV carrier culture are infected and proliferate. Subculti ..."

. Subcultivation under HAV-immune serum cannot achieve a cure or even a reduction in the number of infected cells in HAV carrier cultures. No interferon activity can be detected uring HAV infection and persistence. Addition of exogenous interferon eliminates HAV infection in vitro. Persistence of HAV in vitro
Age- and Sex-Dependent Distribution of Persistent

The colonization of urban and suburban habitats by red foxes (Vulpes vulpes) provides a novel sentinel species to monitor the spread of anthropogenic pollutants in densely populated human settlements. Here, red foxes were collected in the municipal territory of Zürich, Switzerland, and their periren ..."

This pilot study revealed an unexpected pattern of contamination by polychlorinated biphenyls (PCBs), with significantly higher levels of the predominant congeners PCB-138, PCB-153, and PCB-180 in juvenile foxes relative to adult
Upper level set scan statistic for detecting arbitrarily shaped hotspots

Exploiting Hidden Persistent Structures in Multivariate Tensor-Based Morphometry and Its Application to Detecting White Matter
"... Abstract. We present novel multivariate tensor-based morphometry (TBM) for characterizing white matter abnormalities. Traditionally TBM is used in quantifying tissue volume changes in a massive univariate fashion. At each voxel, the Jacobian determinant obtained from TBM is used as the response vari ..."

The proposed methods are applied to quantify abnormal white matter in maltreated children to show multivariate-TBM combined with persistent homology can extract additional information that cannot
