Molecular collisions coming into focus.

The Stark deceleration method exploits the concepts of charged particle accelerator physics to produce beams of neutral polar molecules with an almost perfect quantum state purity, a tunable velocity and a narrow velocity distribution. These monochromatic molecular beams offer interesting perspectives for precise studies of molecular scattering processes, in particular when used in conjunction ...

Correction: Molecular collisions coming into focus.

Some numbers that are given on page 15771 do not correspond to the velocity distributions shown in Fig. 4. In the third paragraph of this page it should read ‘‘The distribution has a width (FWHM) of 4.8 m s 1 and 1.4 m s 1 in the longitudinal and transverse direction, respectively. The velocity distribution can also be expressed as a speed ratio of S = 235 (or a temperature of T = 15.0 mK) and ...

Coming into focus: the nonovarian origins of ovarian cancer.

BACKGROUND The traditional view of epithelial ovarian cancer asserts that all tumor subtypes share a common origin in the ovarian surface epithelium (OSE) DESIGN: A literature review was carried out to summarize the emerging understanding of extraovarian sources of epithelial ovarian carcinomas. RESULTS Historically, there were no diagnostic criteria for documenting the origin of ovarian epit...

Coming Into Focus: An Interview with Ellen Jantzen

Ellen Jantzen: I started life in Missouri, where I was raised and got my first degree in graphic arts. Then I spent about 20 years in Los Angeles, where I got a degree in fashion design and worked for a large corporation. I eventually burned out on the corporate life though. When I was young I thought a full-on artistic life wasn’t practical, so I went into graphic arts and fashion design. When...
