Bleach it, switch it, bounce it, pull it: using lasers to reveal plant cell dynamics.
Since the production of Robert Hooke’s intricate diagrams of the microcomos in the mid-seventeenth century (Hooke, 1665), the use of the light microscope has undergone a technological revolution. Techniques and optics have greatly advanced, allowing us not only to describe the morphology of a specimen but also to probe the movement and dynamics of proteins and organelles within the cell. One of...
متن کاملPull-Ups, Push-Downs, and Passing It Around - Exercises in Functional Incrementalization
Programs in functional programming languages with algebraic datatypes are often datatype-centric and use folds or fold-like functions. Incrementalization of such a program can significantly improve its performance. Functional incrementalization separates the recursion from the calculation and significantly reduces redundant computation. In this paper, we motivate incrementalization with a simpl...
متن کاملPush and Pull Systems
Data broadcasting has emerged as an efficient way for the dissemination of information over asymmetric wireless environments where the needs of the various users of the data items are usually overlapping. In such environments, data broadcasting stands to be an efficient solution since the broadcast of a single information item is likely to satisfy a possibly large number of users. Communication...
متن کاملPush-pull farming systems.
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...
متن کاملA push-pull queueing system
We consider a two node multiclass queueing network given by two machines each with two classes. There are two streams of jobs: One stream originates in machine 1, which feeds it for further processing to machine 2, and the other stream moves in the opposite direction. We describe a policy for this system which is stable and which keeps both machines busy at all times. We obtain explicit express...
