Pixel Club: Image Processing Strategies for 3d Structure Determination of Proteins
- Gabriel Frank (NIH)
- Thursday, 3.9.2015, 11:30
- EE Meyer Building 1061
Structural biology seeks to determine the structure of proteins and other macromolecular assemblies in order to understand of their function. Ground-breaking advances in detectors’ technology and image processing is revolutionizing this field by enabling the application of electron microscopy for 3D structure determination. In this talk I will present the principles of data acquisition and image processing for cryo-electron microscopy. The talk will focus on the unique properties of the images produced by the microscope and on the image processing methods which are currently applied in order to reconstruct 3D structures from these images. Emphasis will be given on describing current limitations and future possibilities.

Efficient Detection Of Flow Anomalies With Limited Monitoring Resources

The real time detection of flow anomalies is a critical part of wide range of management and security applications in many Cloud and NFV systems. Solutions that are based on per-flow records become impossible due to the increasing traffic volumes and the limited available resources such as TCAM entries and fast counters. In this paper we study a novel dynamic control mechanism that allows detecting flow anomalies using only a limited number of counters. Starting from the simple observation that it is impossible to guarantee instantaneous detection of flow anomalies with a limited amount of counters, we study the tradeoff between the time required to detect the anomaly and the number of available counters. We implemented the scheme in an OpenFlow enabled switch, where the logic is implemented in the controller, and demonstrate that it can be used to detect a single flow anomaly within large real traffic volume. To further reduce the detection time, we also implemented the scheme logic inside the switch and used the controller only for configuration. This implementation indeed yields a faster detection and lower monitoring communication overhead while not introducing any significant observable costs at the switch itself.
