Time for Our Field to Grow Up
Compared to centuries of physics and millennia of mathematics, the 50-year-history of computer science and information management research makes us the toddlers of the scientific community. Yet during our brief existence, we’ve revolutionized the world and, not content with that, gone on to build and study virtual worlds. We have justly taken pride in our accomplishments, and developed our own ...
متن کاملWrapping Our Heads around Endocytosis
Eukaryotic cells use a process called endocytosis to take up materials from their environment and package them for use within the cell. The best-studied form of endocytosis—receptor-mediated endocytosis—has several stages. In the first step, the cell’s outer membrane dimples to form a pocket. A protein collar then assembles around this pocket, forming a thin neck leading to a bulb of membrane. ...
متن کاملA Polarization-selective Module for Dense Magneto-optical Pick-up Heads
A polarization-selective holographic optical element with compact dimensions of 2.4mm X 1mm X 1mm (width X length X thickness) is proposed. The element includes three modules: a holographic polarizing beam-splitter, a holographic input coupler, and a dove-prism coupler so that a simple and dense optical pick-up head can be achieved. Polarization properties of holographic volume gratings are bri...
متن کاملLearning To Pick Up a Novel Object
1. Abstract In order for an autonomous robot to successfully function in a natural environment it needs to be able to able to interact with objects it has never seen before. Specifically it needs to be able to manipulate objects in the environment that it has no prior knowledge of. The robot must not only be able to cope with uncertainty in the shape of the object, but also with uncertainty in ...
متن کاملPick up sticks
Break a ruler of length n inches with indentations at each inchmark into n sticks of length one by repeatedly picking up all the fragments which are still of length greater than one and throwing them down all at once until all the sticks are of length one. Assume that each stick breaks into exactly two sticks uniformly at the inchmarks. What is the expected number of throws needed to complete t...
