#1
Richard Huggins, Jakub Stoklosa, Cameron Roach, Paul Yip
Sparse capture-recapture data from open populations are difficult to analyze using currently available frequentist statistical methods. However, in closed capture-recapture experiments, the Chao sparse estimator (Chao, 1989, Biometrics 45, 427-438) may be used to estimate population sizes when there are few recaptures. Here, we extend the Chao (1989) closed population size estimator to the open population setting by using linear regression and extrapolation techniques. We conduct a small simulation study and apply the models to several sparse capture-recapture data sets...

The main aim of the study was to evaluate associations between morphological variability of Trichuris females from sheep and roe deer and their rDNA polymorphism in whipworm populations from the Czech Republic. The results introduced the use of new molecular markers based on the internal transcribed spacer (ITS)1-5.8S RNA-ITS2 region polymorphisms, as useful tools for the unambiguous differentiation of congeners Trichuris ovis and Trichuris discolor. These markers revealed both parasites in roe deer and in sheep; however, T...

Simultaneous treatment of Salix purpurea×viminalis with copper (Cu(2+)) and nickel (Ni(2+)) altered metal phytoextraction rates in favor of leaves. Still, metal translocation patters remained unaffected (roots≈rods>leaves≥shoots), reaching ∼20 and 14.5mgkg(-1) dry weight in roots for Cu and Ni, respectively. Biometric parameters revealed overall growth inhibition correlated with Cu content in leaves, thus proving its negative effect on photosynthesis. Metal toxicity was strongly affirmed in the case of roots (∼90% loss of root biomass at 3mM), rather than in the above-ground organs...

The study of identical twins can point out potential limitations in biometrics and forensic odontology. This case report presents three-dimensional (3D) palatal rugae analysis in monozygotic twins utilizing digital models obtained directly by scanning the maxillary dental arch with the iTero® intraoral digital scanner. The results show that the rugae patterns contain related but not identical features between the pair of identical twins. Dental study models taken on a regular basis for diagnosis and treatment planning in dentistry include the palatal rugae, which could be valuable to forensics in identical twin identification cases...

White-bellied swiftlets of the Collocalia esculenta complex constitute a radiation of colony-breeding swifts distributed throughout the tropical Indo-Pacific region. Resolution of their taxonomy is challenging due to their morphological uniformity. To analyze the evolutionary history of this complex, we combine new biometric measurements and results from plumage assessment of museum specimens with novel as well as previously published molecular data. Together, this body of information constitutes the largest systematic dataset for white-bellied swiftlets yet compiled, drawn from 809 individuals belonging to 32 taxa for which new molecular, biometric, and/or plumage data are presented...

Yasutaka Chiba
Fisher's exact test is commonly used to compare two groups when the outcome is binary in randomized trials. In the context of causal inference, this test explores the sharp causal null hypothesis (i.e. the causal effect of treatment is the same for all subjects), but not the weak causal null hypothesis (i.e. the causal risks are the same in the two groups). Therefore, in general, rejection of the null hypothesis by Fisher's exact test does not mean that the causal risk difference is not zero. Recently, Chiba (Journal of Biometrics and Biostatistics 2015; 6: 244) developed a new exact test for the weak causal null hypothesis when the outcome is binary in randomized trials; the new test is not based on any large sample theory and does not require any assumption...

Hand-foot syndrome, a chemotherapy-induced cutaneous toxicity, can cause an alteration in fingerprints causing a setback for cancer patients due to the occurrence of false rejections. A colon cancer patient was fingerprinted after not having been able to use fingerprint recognition devices after 6 months of adjuvant chemotherapy. The fingerprint images were digitally processed to improve fingerprint definition without altering the papillary design. No evidence of skin toxicity was present. Two months later, the situation returned to normal...

Gait is a commonly used biometric for human recognition. Its main advantage relies on its ability to identify people at distances at which other biometrics fail. In this paper, we develop a new approach for gait recognition that combines the distance transform with curvatures of local contours. We call our gait feature template the normal distance map. Our method encodes both body shapes and boundary curvatures into a novel feature descriptor that is more robust than existing gait representations. We evaluate our approach on the widely used and challenging USF and CASIA-B datasets...

Background When treating recalcitrant and severe childhood obesity, pharmaceutical options are limited and few patients qualify for bariatric surgery. A prolonged inpatient program serves as an alternative treatment. The purpose of this project was to describe the development of a medically supervised inpatient weight management program and evaluate its effectiveness. Methods This is a retrospective chart review of 18 patients [4-18 years, mean body mass index (BMI) 50.2 kg/m2] admitted to an inpatient pediatric weight management program from October 2011 through December 31, 2012 to evaluate the biometric, laboratory, sleep and behavioral changes that occurred from admission to discharge from the program...

The aim of this study was to reconcile three approaches to calculating population attributable fractions and attributable burden percentage; namely the approach of Bruzzi et al. (Am J Epidemiol. 1985;122(5):904-914.), the maximum likelihood method of Greenland and Drescher (Biometrics. 1993;49(3):865-872.), and the multivariable method of Tanuseputro et al. (Popul Health Metr. 2015;13(1)). Using data from a state-wide point prevalence survey linked to an administrative database, we compared estimates of attributable burden percentage obtained using the contrasting methods in six logistic models of health outcomes from the survey, estimating 95% confidence intervals using non-parametric and weighted bootstrap approaches...

Distinguishing between the bones of sheep and goat is a notorious challenge in zooarchaeology. Several methodological contributions have been published at different times and by various people to facilitate this task, largely relying on a macro-morphological approach. This is now routinely adopted by zooarchaeologists but, although it certainly has its value, has also been shown to have limitations. Morphological discriminant criteria can vary in different populations and correct identification is highly dependent upon a researcher's experience, availability of appropriate reference collections, and many other factors that are difficult to quantify...
