D on’t tell your high school football coach, but it is possible to have teamwork even if nobody’s in charge. Inside a cell, for example, myosin VI motors work in concert to haul cargoes along the actin cytoskeleton, Sivaramakrishnan and Spudich reveal (1). Instead of providing muscle power, myosin VI is one of the unconventional myosins whose job is intracellular transportation. Researchers hav...

Farming systems for pest control, based on the stimulo-deterrent diversionary strategy or push-pull system, have become an important target for sustainable intensification of food production. A prominent example is push-pull developed in sub-Saharan Africa using a combination of companion plants delivering semiochemicals, as plant secondary metabolites, for smallholder farming cereal production...

We analyze push and pull for data collection in wireless sensor networks. Most applications to date use the traditional push approach, where nodes transmit sensed data immediately to the sink. Using a pull approach, nodes store the data in their local flash memory, and only engage in communication during dedicated collection phases. We show how one can transform an existing push-based collectio...

OBJECTIVES Overhead athletic activities and scapula dyskinesia are linked with shoulder pathology; pull-ups are a common training method for some overhead sports. Different pull-up techniques exist: anecdotally some are easier to perform, and others linked to greater incidences of pathology. This study aims to quantify scapular kinematics and external forces for three pull-up techniques, thus d...

Real life networks are generally modelled as scale-free networks. Information diffusion in such networks in decentralised environment is a difficult and resource consuming affair. Gossip algorithms have come up as a good solution to this problem. In this paper, we have proposed Adaptive First-Push-Then-Pull gossip algorithm. We show that algorithm works with minimum cost when the transition rou...

An XML parser facilitates in simplifying the process of manipulating XML documents. The two commonly used models for parsing XML are pull and push. The Simple API for XML (SAX) [5] is the industry standard for parsing based on the push model. However, no standard exists for pull parsing. In this paper we propose the design, API and implementation, XML Pull Parser 2.0 (XPP2), that allows for bot...

Pull-off adhesion fb, in practice determined by the seminondestructive pull-off method, is a measure of the interlayer bond. It should be noted that the effectiveness of the pull-off method depends on the number of cores drilled. According to [1], one core per 3 m2 of floor should be drilled. Such a high density of cores drilled has a significant adverse effect on the condition of the tested fl...
