In our second installment of the infrared (IR) spectra polymers, we finish discussion spectrum polyethylene (PE) started last time. We explore how different PE syntheses produce materials with physical and spectroscopic properties, which introduces us to concept crystalline splitting rest story on CH2 rocking peaks.

This is the fourth installment intended to address outstanding taxonomic matters in bee genus Scaptotrigona Moure (Meliponini). Four new species of postica group (group B) are described and figured as: (Scaptotrigona) anaulax Engel, species, from Ecuador; S. (S.) vitorum semiflava Bolivia Peru; grueteri Bolivia.

In human-human conversation, people spontaneously adjust their verbal and nonverbal behaviors to each other-most of the time without being aware it. This installment Computer's series highlighting work published in IEEE Computer Society journals comes from Transactions on Affective Computing.

Building Community Systems for Young Children is a series of reports designed to support the implementation of Proposition 10: The California Children and Families Act. Each installment is written by a team of experts and provides comprehensive and authoritative information on critical issues concerning young children and families in California. Building Community Systems for Young Children has...

We are pleased to present a series of Annotated Classics celebrating 40 years of exciting biology in the pages of Cell. This installment revisits “Functional Demarcation of Active and Silent Chromatin Domains in Human HOX Loci by Noncoding RNAs” from Howard Chang’s lab. Here, Irene Bozzoni comments on how Rinn et al. ignited our appreciation for the ability of noncoding RNAs to regulate key cel...

Part I of this tutorial described two broad paradigms of interventional assistance: surgical computer-aided design (CAD)/computer-aided manufacturing (CAM) and surgical assistance. Part II focused on the underlying concepts of surgical CAD/CAM, with a particular emphasis on percutaneous procedures. This final installment of our three-part tutorial series discusses surgical assistance. In this s...

In this third installment of the series, we point out that the absence of an explicit, detailed and plausible hypothesis linking hypercholesterolemia to the events in the artery wall was probably an important reason for continuing skepticism and for failure to treat elevated blood cholesterol levels. The rapid advances in understanding of lipoprotein metabolism in the 1950s and 1960s and the ap...

This paper describes the concept of improving operation of a distribution circuit of the future through installment of interoperable devices, including distributed energy resources (DER) that are controlled using a multi-agent system approach. This concept for improving distribution service is being considered by SCE’s DER Program, with additional assistance from West Virginia University in the...

Editor’s Note: This is the first installment of a two-part post by Amitai Etzioni examining the nation’s anti-obesity policies through the lens of a responsive communitarian philosophy. Today, Etzioni lays out a responsive communitarian framework and uses it to diagnose the problems with our current methods of fighting obesity. Tomorrow , Etzioni describes how these current policies should be r...
