data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
New biphasic conditions for the palladium-catalyzed direct arylation of electron-poor fluorinated arenes have been developed. Taking advantage of biphasic chemistry, the use of an immiscible mixture of water and an organic solvent allows complete solubilization of all components of the system, enabling the reaction to proceed at room temperature in yields up to 99%.
Cytokinesis is regulated by both astral microtubules and the midzone microtubules of the mitotic apparatus. A new study in Caenorhabditis elegans has identified the polarity factor LET-99 and its heterotrimeric G-protein regulators as components of the signaling pathway downstream of astral microtubules.
