T he business environment is characterized by environmental and exogenous factors that affect company performance to the extent that it prevents managers from interacting effectively with a company. This study built on the literature on the ease of doing business and capital flight by empirically demonstrating the importance of business environments across different countries. To thi...

The erect wing locus of the fruit fly Drosophila melanogaster encodes a protein, EWG, that shares extensive homology with the P3A2 DNA binding protein of sea urchin and a recently identified mammalian transcription factor. Loss-of-function erect wing alleles result in embryonic lethality. Viable alleles of erect wing cause severe abnormalities of the indirect flight muscles. We have analyzed th...

Formation flight is the primary movement technique for teams of helicopters. However, the potential for accidents is greatly increased when helicopter teams are required to fly in tight formations and under harsh conditions. The starting point for safe autonomous flight formations is to design a distributed control law attenuating external disturbances coming into a formation, so that each vehi...

The bidirectional reflectance distribution function (BRDF) of the Earth’s surface describes the directional and spectral variation of reflectance of a surface element. It is required for precise determination of important geophysical parameters such as albedo. BRDF can be estimated using reflectance data acquired at large 3D angular spread of solar illumination and detector directions and visib...

OBJECTIVE Children and adults with type 1 diabetes who receive insulin pump therapy have reported hypoglycemia during air travel. We studied the effects of atmospheric pressure on insulin pump delivery. RESEARCH DESIGN AND METHODS Ten insulin pumps were connected to capillary tubes. The effects of changes in ambient pressure on insulin delivery, bubble formation, bubble size, and cartridge pl...
