Near the end of 2001 February, the black-hole candidate (BHC) GRS 1758–258 made an abrupt transition from a standard hard (low) state to a soft state. Unlike Cyg X–1 and other BHCs, whose luminosity increases during this transition, GRS 1758–258 was dimmer after the transition. We present observations with the Proportional Counter Array on the Rossi X-ray Timing Explorer and interpret the pheno...
We present revised infrared (2.2μm) astrometry of the field containing the Galactic microquasar GRS 1758−258, using observations at the Keck I 10-m telescope. We find three candidates for the microquasar within a 3σ error circle, but none within 2σ. We show that if the 18.4 day X-ray period of GRS 1758−258 is due to a binary orbit, then only one of the three candidates, an early K-type giant, i...
Frequent genetic alterations discovered in FGFRs and evidence implicating some as drivers in diverse tumors has been accompanied by rapid progress in targeting FGFRs for anticancer treatments. Wider assessment of the impact of genetic changes on the activation state and drug responses is needed to better link the genomic data and treatment options. We here apply a direct comparative and compreh...

This study investigated the self-reported effects of Internet use on faculty at small Christian colleges and universities by age, years of Internet use, academic field, and on faculty communication style, teaching style, personal productivity, fulfillment of the organization’s mission, social networks, research, and professional development. Findings: Faculty believed that their communication h...
OBJECTIVE To investigate patient perceptions and the impact of participating in the Royal College of Physicians and Surgeons of Canada (RCPSC) long case oral examination. METHOD Immediately following the RCPSC exam, participating psychiatric patients completed a Participant Impact Questionnaire. We combined results for 2002 and 2003 from both the western and eastern sites. RESULTS Overall, ...
