[1] We use planktonic oxygen isotope (dO) records spanning the last 30,000 years (kyr) to constrain the magnitude and spatial pattern of glacial cooling in the upwelling environment of the eastern equatorial Pacific (EEP). Fourteen new downcore dO records were obtained from surface-dwelling planktonic foraminifera Globigerinoides sacculifer and Globigerinoides ruber in eight cores from the upwe...

where d is the distance between the center of masses of the two symmetrical halves of the CSAs. Critical to the use of this theorem is the determination of the exact center of mass of each CSA (6, 7). The authors did not specify how the center of mass was determined nor the accuracy, precision, and variation of this measurement in the bovine lens. There are additional significant deficiencies w...

The changing configurations of continents due to plate tectonics is thought to be responsible for some of the variation in climate over the last 600 Ma. Different topological constraints on the oceans may affect their ability to transport heat poleward and change the equilibrium pole-equator temperature of Earth. An ocean model was run for three simple continental geometries to determine the ef...

Motility is a fundamentally important property of most members of the kinesin superfamily, but a rare subset of kinesins are also able to alter microtubule dynamics. At kinetochore-microtubule plus ends, the kinesin-8 family member Kif18A is essential to align mitotic chromosomes at the spindle equator during cell division, but how it accomplishes this function is unclear. We report here that K...

Members of host species in pathogen-host coevolutionary races may be selected to choose mates who possess features of physical appearance associated with pathogen resistance. Human data from 29 cultures indicate that people in geographical areas carrying relatively greater prevalences of pathogens value a mate’s physical attractiveness more than people in areas with relatively little pathogen i...

Two hundred and five healthy Malaysian adults were scanned for the length of their kidneys and the cortical thickness by both the sector real time and linear array static B-scan diagnostic ultrasound. The length of the left kidney was found to measure 105 (98-111) mm for males, and 100 (94-106) mm for females on average from the sector scan and the static B-scan. The right renal length was 102 ...

The combination of the Voyager spacecraft in the outer heliosphere, Ulysses at high latitudes, and multiple solar wind monitors near Earth provides a unique opportunity to study the global structure and evolution of the solar wind. From solar minimum to solar maximum the latitudinal gradients of density and speed reverse so that at solar maximum speeds are higher near the solar equator, but sol...

Equator-S frequently encountered, i.e. on 30% of the orbits between 1 March and 17 April 1998, strong variations of the magnetic ®eld strength of typically 5±15-min duration outside about 9RE during the late-night/early-morning hours. Very high-plasma beta values were found, varying between 1 and 10 or more. Close conjunctions between Equator-S and Geotail revealed the spatial structure of thes...

It has been suggested that impaired left ventricular performance in patients with rheumatic mitral stenosis results from a localized abnormality of wall motion. Accordingly, in io patients with isolated mitral stenosis who had no evidence of coronary arterial disease, the ejection fraction and the mean rates of circumferential fibre shortening (mean Vcf) both at the minor equator and at the bas...
