- Extensive experimental data from high-energy nucleus-nucleus collisions were recorded using the PHENIX detector at the Relativistic Heavy Ion Collider (RHIC). The comprehensive set of measurements from the first three years of RHIC operation includes charged particle multiplicities, transverse energy, yield ratios and spectra of identified hadrons in a wide range of transverse momenta (PT), elliptic flow, two-particle correlations, nonstatistical fluctuations, and suppression of particle production at high PT. The results are examined with an emphasis on implications for the formation of a new state of dense matter. We find that the state of matter created at RHIC cannot be described in terms of ordinary color neutral hadrons.

- The characteristics of liquid -> delta ferrite and delta ferrite -> gamma austenite transformation in Fe-3.50 at. pct Ni alloy, and of the peritectic solidification of Fe-4.83 and 5.01 at. pct Ni alloys, have been dynamically observed in situ with a confocal scanning laser microscope (CSLM) combined with an infrared image furnace (IIF). The unique sequence, morphologies, and rates of these transformations have been determined at a temperature gradient of 4 K/mm and growth rates of 2 to 3 mu m/s, in unidirectional solidification experiments. These observations have been discussed in terms of the constitutional undercooling description of solidification theory.

- The dementia with Lewy bodies (DLB) Consortium has revised criteria for the clinical and pathologic diagnosis of DLB incorporating new information about the core clinical features and suggesting improved methods to assess them. REM sleep behavior disorder, severe neuroleptic sensitivity, and reduced striatal dopamine transporter activity on functional neuroimaging are given greater diagnostic weighting as features suggestive of a DLB diagnosis. The 1-year rule distinguishing between DLB and Parkinson disease with dementia may be difficult to apply in clinical settings and in such cases the term most appropriate to each individual patient should be used. Generic terms such as Lewy body (LB) disease are often helpful. The authors propose a new scheme for the pathologic assessment of LBs and Lewy neurites (LN) using alpha-synuclein immunohistochemistry and semiquantitative grading of lesion density, with the pattern of regional involvement being more important than total LB count. The new criteria take into account both Lewy-related and Alzheimer disease (AD)-type pathology to allocate a probability that these are associated with the clinical DLB syndrome. Finally, the authors suggest patient management guidelines including the need for accurate diagnosis, a target symptom approach, and use of appropriate outcome measures. There is limited evidence about specific interventions but available data suggest only a partial response of motor symptoms to levodopa: severe sensitivity to typical and atypical antipsychotics in similar to 50%, and improvements in attention, visual hallucinations, and sleep disorders with cholinesterase inhibitors.

- Objectives To develop interactive computer-assisted learning software for teaching dental students to logically arrange periapical and bitewing radiographs. Methods Using the Microsoft Visual Basic.NET programming language, we developed software comprising an original object menu window, workspaces, and functions for radiograph shuffling, rotating, mounting, clock, evaluation, score, easy addition of images, a virtual teacher, and help menus. We also developed a program called “Mounting of Dental Radiographs,” which is composed of dental images, a menu window, workspaces, and functions. Results On starting the program, randomly ordered radiographs from a full-mouth X-ray exam are presented, and the clock starts. The student selects one image at a time and places it in the proper folder. An image may need to be rotated or turned. When all images are mounted, the virtual teacher checks the results. If the images have not all been placed correctly within the time limit, the student is given two more attempts before being told, “You lost.” This software can be easily and quickly modified, and dates and scores can be saved automatically. Conclusions We developed a versatile, interactive software program to help students understand how to mount dental X-ray images. It can be modified easily to suit the needs of different students.
