We describe the synthesis and fluorescence properties of a Fura-2FF-based fluorescent Ca(2+) indicator that can be covalently linked to SNAP-tag fusion proteins and retains its Ca(2+) sensing ability after coupling to protein.

We demonstrate that an oft-used indirect attitude assessment technique—the attitude activation paradigm—accurately assesses attitudes only when participants attend to the prime stimuli during the attitude activation task. Attitude activation attitudes toward obviously valenced words (e.g., torture, liberty) were more sensitive to attitude valence and extremity when participants were required to...

How well does Prizma’s poverty scorecard identify poor clients? The scorecard applies 0/1 weights to seven simple and inexpensive-to-collect indicators to give a score from 0 (most likely poor) to 9 (least likely poor). The scorecard has good power, not only for ranking clients by relative poverty but also for identifying the likelihood that a client is poor by an absolute standard. While pover...

BACKGROUND There is a dire need in the Arab world and Middle Eastern countries to reform the higher education, research policy and planning for improving the quality to meet the needs of modern society. The impact factor (IF) was developed in the 1960s by Eugene Garfield of the Institute for Scientific Information (ISI) in the USA. It has been extensively used for more than 40 years. The SCImag...

Metrics based on percentile ranks (PRs) for measuring scholarly impact involves complex treatment because of various defects such as overvaluing or devaluing an object caused by percentile ranking schemes, ignoring precise citation variation among those ranked next to each other, and inconsistency caused by additional papers or citations. These defects are especially obvious in a small-sized da...

Frequently, ontologies based on the same domain are similar but also have many differences, which are known as heterogeneity. The alignment of entities which are not meant to be used in the same context, or which follow different modeling conventions, may cause mismatch in ontology alignment. End-users would benefit from knowing the risk level of mismatch between ontologies prior to starting a ...
