Priming effects of cooperation vs. individualism were investigated on changeover speed within a 4 x 100-m relay race. Ten teams of four adult beginner athletes ran two relays, a pretest race and an experimental race 3 weeks later. Just before the experimental race, athletes were primed with either cooperation or individualism through a scrambled-sentence task. Comparing to the pretest performan...

This paper presents a new hierarchical distributed communication architecture, called AHS (Auction Handling System), based on clusters. This architecture uses the IRC (Internet Relay Chat) channels and protocol facilities in order to support real-time auction applications (RTA). Coordination between distributed auction servers is needed to exchange and update some relevant auction information a...

This paper presents an overview of solutions proposed in the literature for the overcurrent relay coordination problem in the presence of distributed generators (DGs). Furthermore, several protection issues are identified to study the requirements for protection in the presence of DGs, and possible innovative solutions for resolving the operational conflicts between distribution networks and DG...

Proton relay plays an important role in many biocatalytic pathways. In order to mimic such processes in the context of molecular switches, we developed coordination-coupled deprotonation (CCD) driven signaling and signal enhancement sequences. This was accomplished by using the zinc(ii)-initiated CCD of a hydrazone switch to instigate an acid catalyzed imine bond hydrolysis that separates a que...

Industrial Automation has evolved from stand-alone, hard-wired relay panels to a contemporary, networked system that supports flexible manufacturing and enterprise integration. From precision control of machines and robots on the factory floor to flexible coordination of multiple cells of automation, advancements in control technologies have driven the evolution of industrial automation. The co...

Signal transduction pathways converge upon sequence-specific DNA binding factors to reprogram gene expression. Transcription factors, in turn, team up with chromatin modifying activities. However, chromatin is not simply an endpoint for signaling pathways. Histone modifications relay signals to other proteins to trigger more immediate responses than can be achieved through altered gene transcri...

In this paper, an iterative incremental relay selection (IIRS) scheme is considered for wireless cooperative networks in order to increase the reliability of transmission. Different from the conventional incremental relay selection which incrementally selects a best relay for only one iteration; the IIRS scheme iteratively applies the incremental relaying and relay selection processes. To evalu...

Signal Amplification by Reversible Exchange (SABRE) is used to switch on the latent singlet spin order of para-hydrogen (p-H2) so that it can hyperpolarize a substrate (sub = nicotinamide, nicotinate, niacin, pyrimidine, and pyrazine). The substrate then reacts reversibly with [Pt(OTf)2(bis-diphenylphosphinopropane)] by displacing OTf- to form [Pt(OTf)(sub)(bis-diphenylphosphinopropane)]OTf. Th...

Penetration of the power grid by renewable energy sources, distributed storage, and generators is becoming increasingly common. Increased utilization these resources (DERs) has given rise to additional protection coordination concerns, particularly where they are utilized in an unbalanced manner or loading among phases unbalanced. Digital relays such as SEL-751 (produced Schweitzer Engineering ...
