Let X 1, ···, Xn be i.i.d. random variables defined in ℝ d having common continuous density f(x), and let Rij be the rank of Xj in the ordered list of distances from X¡. Both the mutual neighbor probabilities p 1(r, s) = P(R 12 = r, R 21 = s) and the . . .

Both pharmacological intervention (i.e., thiazolidinediones [TZDs]) and lifestyle modification (i.e., exercise training) are clinically effective treatments for improving whole-body insulin sensitivity. However, the mechanism(s) by which these therapi . . .

I've just come back from attending both the Special Libraries Association (SLA) Annual conference in San Antonio and the American Libraries Association (ALA) Annual conference in San Francisco. I'm sure I've gone to every SLA conference for the last 1 . . .

Context. Based on the viscous disk theory, a number of recent studies have suggested there is large-scale meridional circulation in protoplanetary disks. Such a flow could account for the presence of crystalline silicates, including calcium- and alumi . . .

We have discovered an extremely red object, LSF 1, located 7" southwest (P.A. 217 degrees) of the bright spectroscopic binary system HD 155826. Originally reported by IRAS as one source detected at 12-60 ?m, and found as a single 6-25 ?m source of sim . . .

Despite the wide reach of medical licensing in health care production through its impact on the nature and cost of care, it has been all but ignored in debates over health care reform. This paper pulls together statements made by economists whose expe . . .

The SuperWASP cameras are wide-field imaging systems at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, and at the Sutherland Station of the South African Astronomical Observatory. Each instrument has a fie . . .

A new method is devised for calculating the Igusa local zeta function Z_f of a polynomial f(x_1,,,,,x_n) over a p-adic field. This involves a new kind of generating function G_f that is the projective limit of a family of generating functions, and con . . .

Under high pressure, triply bonded molecular nitrogen dissociates into singly bonded polymeric nitrogen, a potential high-energy-density material. The discovery of stable high-pressure forms of polymeric nitrogen is of great interest. We report the st . . .

A commentary discusses negotiations between the Purdue University faculty and Elsevier Science Inc. over the cost of Elsevier journals. The average cost for a science and technology periodical has increased 50% since 1992. The larger the price increas . . .
