Changes in the isometric tension of isolated strips of cutaneous, femoral, mesenteric, pulmonary, and muscle arteries and veins were recorded at 37°C in an organ bath. Acetylcholine (5 X 10~ and 10"' g/ml) caused relaxation of strips from the saphenous veins, the femoral veins, and all of the arteries after contraction by norepinephrine released from nerve terminals by electrical stimulation (2...

We consider a set of axis-parallel nonintersecting strips in the plane. An observer starts to the left of all strips and ends to the right, thus visiting all strips in the given order. A strip is inspected as long as the observer is inside the strip. How should the observer move to inspect all strips? We use the path length outside a strip as a quality measure which should be minimized. Therefo...

BACKGROUND Tapering strips can be used for the gradual reduction of the dose of certain types of drugs such as antidepressants and benzodiazepines. The strips contain a slightly lower dose on each consecutive day. This prevents the withdrawal symptoms still experienced by too many patients and lowers the risk of relapse. AIM To make tapering strips of antidepressant drugs available for patien...

Loss of biodiversity and degradation of ecosystem services from agricultural lands remain important challenges in the United States despite decades of spending on natural resource management. To date, conservation investment has emphasized engineering practices or vegetative strategies centered on monocultural plantings of nonnative plants, largely excluding native species from cropland. In a c...

Stomata in epidermal strips of Vicia faba opened in light and closed in darkness when floated on dilute K(+) solutions. Opening and closing, respectively, paralleled the fluxes of labeled K(+) into and out of the strips. The gain and loss of K(+) by the strips were shown by colbaltinitrite stain to be centered at guard cells. Intact epidermal cells, however, appeared to take up K(+), complicati...

LiDAR systems have been established as technology for fast and high-resolution acquisition of 3D point clouds. In general, LiDAR data acquisition is conducted by private companies who are also responsible for processing and quality control. However, in many cases a subsequent quality assessment of overlapping LiDAR strips still reveals apparent horizontal and vertical offsets which are caused b...

Temporal planning (TP) is notoriously difficult because it requires to solve a propositional STRIPS planning problem with temporal constraints. In this paper, we propose an efficient strategy for solving TP, which combines, in an innovative way, several well established and studied techniques in AI, OR and constraint programming. Our approach integrates graph planning (a well studied planning p...
