Miller et al. (2005) assert that the estimate of White et al. (2005) of 1.94% of eastern Colorado being occupied by black-tailed prairie dogs (Cynomys ludovicianus) was biased high. The subsequent surveys conducted by Miller et al. (2005) do not provide a valid bias correction for the estimate of White et al.

A Novel Ship Speed and Heading Estimation Approach Using Radar Sequential Images
IEEE transactions on intelligent transportation systems (Print), 2023This paper proposes an approach to estimate ship dynamic features (i.e., speed and heading) using radar sequential images, which can be used to assess the ship-ship collision risk in vessel traffic service (VTS) center.

A patient with elevated alkaline phosphatase underwent whole body bone imaging with Tc-99m methylenediphosphonate. Pelvic and lower extremity images showed typical widening and increased density along trabecular and cortical lines typical for Paget's disease. The lateral skull view is remarkable for its head-within-a-head appearance. The posterior view,

Head to head polymers. XVII: Head to head polypropylene
Monatshefte f�r Chemie, 1981Head to head polypropylene was prepared by catalytic hydrogenation of eithercis-1,4-poly(2,3-dimethylbutadiene) ortrans-1,4-poly(2,3-dimethylbutadiene) with cobalt 2-ethylhexanoate/triethylaluminium as the hydrogenation catalyst in decahydronaphthalene solution.

A clock regulatory module is required for salt tolerance and control of heading date in rice.
Plant, Cell and Environment, 2021The circadian clock plays multiple roles in plant stress responses and developmental transition phases. Nevertheless, the underlying molecular mechanisms and individual clock components that coordinately regulate important agronomic traits of rice such ...
