چکیده

I am delighted to introduce Jamie Elsila as the recipient of this year's Jessberger Award. met after she returned from service in Peace Corps Tanzania between college and graduate school, where taught chemistry math. She visited NASA Ames with Society Fellow Scott Sandford had done undergraduate research published her first paper (Elsila et al., 1997) (Figure 1). was a post-doc pleasure working when student Dick Zare meteoritic publication 20 years ago (Plows 2003) received PhD 2004. As large cuts NASA's astrobiology program were being proposed 2006, Nier Prize winner, Danny Glavin fortune get funding for new isotope ratio mass spectrometer 2) well hiring point civil servant scientist join our laboratory at Goddard Space Flight Center compound-specific measurements needed firmly establish origin amino acids detected meteorites samples comet Wild 2 by Stardust mission. senior that same Ames, modest experience stable work but keen interest extraterrestrial organic chemistry. encouraged apply; did hired top candidate. Then, now, can master topic became expert challenging field trace organics samples. In particular, analysis foil extracts proved be extremely difficult.

In vitro–in vivo correlation (IVIVC) of intrinsic clearance in preclinical species of rat and dog was established using the hepatocyte relay method to support high-confidence prediction of human pharmacokinetics for low-clearance compounds. Good IVIVC of intrinsic clearance was observed for most of the compounds, with predicted values within 2-fold of the observed values. The exceptions involve...

Cerlapirdine (SAM-531, PF-05212365) is a selective, potent, full antagonist of the 5-hydroxytryptamine 6 (5-HT6) receptor. Cerlapirdine and other 5-HT6 receptor antagonists have been in clinical development for the symptomatic treatment of Alzheimer’s disease. A human absorption, distribution, metabolism, and excretion study was conducted to gain further understanding of the metabolism and disp...

Tissue homeostasis is maintained by adult stem cells, which selfrenewand give rise to differentiating cells. The generation of daughter cells with different fates is mediated by signalling molecules coming from an external niche or being asymmetrically dispatched between the two daughters upon stem cell mitosis. In the adult Drosophila midgut, the intestinal stem cell (ISC) divides to generate ...

INTERSECTING RATIONAL BEATTY SEQUENCES Jamie

A rational Beatty sequence has the form {�pi/q + b� : i ∈ Z} where p > q > 0 and gcd(p, q) = 1. We call p/q the modulus of the sequence and b the offset. Morikawa gave a condition on the moduli of two Beatty sequences such that they would be disjoint for a suitable choice of offsets. Holzman and Fraenkel showed that the sequence formed by the intersection of two Beatty sequences with moduli p1/...
