Analyzes a group of 23 freshwater “Edison” pearls (a trade name referring to near-round cultured pearls, usually shell bead cultured) using various gemological and advanced instrumental techniques.

The goal is to collect pearls (small golden circles) by sliding a droplet of water (large blue circle) over them in a grid map. The map contains obstacles (square blocks). In each move, the droplet slides in one of the four directions to the maximal extent, until it is stopped by an obstacle. 7 Moves! left (1st pearl) up, left (2nd pearl) down, right, up, left (3rd pearl) The map contains only ...

In recent years, coal production and consumption increased dramatically, especially in China. So, more and more attentions have been paid to coal preparation and coal ash utilization with the growing concern about the pollution by fly ash. The unburned carbon in fly ash significantly affects its utilization in many fields, especially in concrete production industry. Technologies such as flotati...

eneral A t the 2001 Annual Conference of the American College of Physicians, a new teaching format to aid physician learning, Clinical Pearls, was introduced. Clinical Pearls is designed with the 3 qualities of physician-learners in mind. First, we physicians enjoy learning from cases. Second, we like concise, practical points that we can use in our practice. Finally, we take pleasure in proble...

What do you think about highimpact journals that cater to a wider audience? I used to think that such journals were for the vain and insecure; however, I’ve just had my first article accepted by Current Biology, so I must of course reconsider. I think there is a place for journals suited to the more general reader, but I do worry that the decisions for some journals — even on whether to send th...

The Program to Encourage Active, Rewarding Lives (PEARLS) began 15 years ago when the director of our local area agency on aging (AAA) approached the University of Washington Health Promotion Research Center (HPRC). She was looking for a way to serve older adults with depression, including those served by the agency’s home and community-based services (HCBS) program. Depression in this populati...

Gold and pearls: Multifunctional nanoparticles, each composed of a single, amine-modified gold nanorod, decorated with multiple "pearls" of Fe(3)O(4) nanoparticles capped with carboxy groups, are prepared. Their effectiveness in simultaneous targeting, dual-mode imaging, and photothermal ablation of breast cancer cells is demonstrated.

Well-trained experts in pearl grading have been thought to evaluate pearls according to their glossiness, interference color, and shape. However, the characteristics of their evaluations are not fully understood. Using pearl grading experiments, we investigate the consistency of novice (i.e., without knowledge of pearl grading) and expert participants' pearl grading skill and then compare the n...
