DNA-based capture-mark-recapture (CMR) techniques are commonly used to obtain population parameters of black bears (Ursus americanus) in rural and wildland landscapes; however, these techniques have not been implemented in urban clusters (i.e., 2,500 to 50,000 residents). Black bears can readily habituate to urban clusters, and wildlife managers need to monitor and manage these urban bear popul...

This paper describes a method of human short hair modeling and real time animation. A method is proposed to model the short hair. First, a hair style model is derived from a scalp model interactively. Then, the hair model is derived automatically from the hair style and scalp models. Texture mapping is applied to hair model for a better visual effect. For animation, a method is proposed based o...

We report a genome-wide association scan in over 6,000 Latin Americans for features of scalp hair (shape, colour, greying, balding) and facial hair (beard thickness, monobrow, eyebrow thickness). We found 18 signals of association reaching genome-wide significance (P values 5 × 10(-8) to 3 × 10(-119)), including 10 novel associations. These include novel loci for scalp hair shape and balding, a...

BACKGROUND A number of otherwise healthy women with or without clinical alopecia complain of recurrent hair loss, presumably reflecting seasonality in the growth and shedding of hair. OBJECTIVE To test the hypothesis that periodicity in hair shedding reflects seasonal changes in human hair growth. METHODS Retrospective case study over a period of 6 years of apparently healthy women with the...

As virtual humans appear more frequently in various fields such as movies, video games, commercial films, and virtual reality, it becomes increasingly important to display them realistically. However, expressive wrinkles and dynamic hair, which play crucial parts in synthesizing an impressive human head model, are generally difficult to model and animate interactively because of their complexit...

The hair follicle is a skin integument at the boundary between an organism and its immediate environment. The biological role of the human hair follicle has lost some of its ancestral importance. However, an indepth investigation of this miniorgan reveals hidden complexity with huge research potential. An essential consideration when dealing with human research is the awareness of potential har...

In order to establish guidelines for exposure of astronauts to iodine, used as a water disinfectant in space, we studied the usefulness of hair, saliva, and urine for biological monitoring in humans and in the human hair/nude mouse model. The monitoring of iodine in patients that received 150 mCi of Na131I (carrier-free) showed similar patterns of elimination for blood, saliva, and urine. The m...
