Processes of regeneration and reorganization are analyzed in two sabellid polychaetes. Abdominal pieces of Branchiomma nigromaculata, during head regeneration, ordinarily reorganize only a fraction of the number of segments typical of the thorax. In pieces transected in the vertical plane, but obliquely with regard to the main axis of the worm, the extent of reorganization is greatly enhanced. ...

Background Recently, compelling data have been published on the value of salivary gland ultrasound (SGUS) in differentiating between primary Sjögren’s Syndrome (SS) from nonimmune-mediated sicca syndrome. Limited are available regarding diagnostic accuracy SGUS to distinguish SS undifferentiated connective tissue diseases associated with Objectives The aim this study was evaluate power patients...

Background Sicca syndrome represents a heterogeneous group of conditions, including Sjögren syndrome, causing xerophthalmia and xerostomia. Objectives This study characterizes in depth patients with evaluates salivary gland ultrasound (SGUS) this cohort. Methods Principal component analysis hierarchical clustering clinical parameters, ESSPRI, ESSDAI laboratory data were performed on all referra...

There are two common types of solution methods for solving simple integrals: using integration constants or using limits of integration. We use the resources framework to model student solution methods. Preliminary results indicate both problematic and meaningful intersections of physical meaning and mathematical formalism when solving linked integrals. Students solving separable first order di...

Most important research results that explain why the work was done, what was accomplished, and how it pushed scientific frontiers or advanced the field. Diamond holds substantial promise as a high Raman gain laser material with outstanding power handling capability, yet despite this the highest reported output power from a diamond Raman laser prior to this project was approximat...

Quantitative multilevel research has advanced organizational science, but is limited because the focus is incomplete. Most research examines top-down, contextual, cross-level relationships. Emergent phenomena – those that manifest bottom-up from the psychological characteristics, processes, and interactions among individuals – have been largely neglected. Emergence is theoretically assumed, exa...
