Tomographic Magnetic Particle Imaging with a Single-Sided Field-Free Line Scanner.

Objective: Magnetic Particle Imaging (MPI) is a biomedical imaging modality that shows promise in enhancing clinical imaging capabilities. While there are current efforts to expand MPI hardware to enable wholebody and head imaging, this comes at a significant cost in terms of complexity and expense.

Methods: A single-sided scanner can offer greater accessibility to the scanning area, as all hardware is located on one side of the device's surface, however, at the price of the limited penetration depth.

Mercury bioaccumulation in an estuarine predator: Biotic factors, abiotic factors, and assessments of fish health.

Estuarine wetlands are major contributors to mercury (Hg) transformation into its more toxic form, methylmercury (MeHg). Although these complex habitats are important, estuarine Hg bioaccumulation is not well understood. The longnose gar Lepisosteus osseus (L.

Teaching skills to use a computer mouse in preschoolers with developmental disabilities: shaping moving a mouse and eye-hand coordination.

We taught seven preschoolers with developmental disabilities to point-and-click with a computer mouse. The computer-based training program consisted of three parts, based on a task analysis of the behavioral prerequisites to point-and-click. Training 1 was designed to shape moving the mouse.

Programmed Instruction to teach pointing with a computer mouse in preschoolers with developmental disabilities.

Programmed Instruction combined with experimenter-provided prompts (physical, verbal, and gesturing) was used to teach pointing with a computer mouse. Three preschoolers who scored at least 1 year below their chronological age levels participated. During the pre-assessment, none of the participants demonstrated pointing.

Dialogue on private events.

In the fall of 2003, the authors corresponded on the topic of private events on the listserv of the Verbal Behavior Special Interest Group. Extracts from that correspondence raised questions about the role of response amplitude in determining units of analysis, whether private events can be investigated directly, and whether covert behavior differs from other behavior except in amplitude. Most participants took a cautious stance, noting not only conceptual pitfalls and empirical difficulties in the study of private events, but doubting the value of interpretive exercises about them.
