An atomic force microscope is used to scribe polymer-coated substrates to create an electrically-controlled polarization grating. The grating is nondiffracting in the voltage-off state and diffracting in the voltage-on state. Based upon an optical phase difference of approximately π between adjacent pixels, the grating’s efficiency is independent of optical polarization and can be prepared for ...

Preface These are lecture notes for a course taught in Cambridge during Lent 2014 by Jack Button, on a topics in infinite group theory. There are likely to be errors, which are solely the fault of the scribe. If you discover any, please contact me [email protected].

The lecture can be divided into two parts. The first part of the lecture is based on: A perspective on Multi-Access Channels by Robert G. Gallager. The paper is GALLAGER, R. A Perspective on Multi-Access Channels. IEEE Transactions on Information Theory, 31(2):124-142, 1985. The second part of the lecture is based on: An Asymptotically Nonadaptive Algorithm for Conflict Resolution in Multiple-A...

1 Recap Last lecture we started to look at how we could realize any two-party functionality for any number of faults in the F CRS-hybrid model. In this lecture we will finish this discussion and extend it to the multi-party case. We will also note that we can get rid of the CRS in the case of an honest majority. All the material in this lecture is taken from [CLOS02]. In more detail, we follow ...

In this course we will study techniques for designing and analyzing algorithms. Undergraduate algorithms courses typically cover techniques for designing exact, efficient (polynomial time) algorithms. The focus of this course is different. We will consider problems for which polynomial time exact algorithms are not known, problems under stringent resource constraints, as well as problems for wh...

• Two auditors: one to ask open questions, the other as witness and scribe. • Interview staff individually, establishing their knowledge of trial procedures and incident. Note conflicting information. • Establish key facts: 1. Were participants real and eligible? 2. Did they consent? 3. Are test/clinical measurements/data valid? 4. Was appropriate treatment/intervention given? 5. Was follow-up ...

Lecturer: Haim Permuter Scribe: Shai Shapira and Uri Livnat " The probability of an event is the ratio of the number of cases favorable to it, to the number of all cases possible when nothing leads us to expect that any one of these cases should occur more than any other, which renders them, for us, equally possible. " Probability space formalizes three interrelated ideas by three mathematical ...

By a somewhat democratic process, it was established that the graded work for the course will be two-fold: scribe notes (such that the participants and the instructor emerge with a relatively complete set of lecture notes) and homework exercises (probably three sets of challenging-butnot-life-threatening problems, such that everybody gets some practice solving problems and the instructor may om...

Deciding to become a physician is by far the greatest commitment I have ever made. At the end of it all, I will have spent over 20 years in school and several hundred thousand dollars paying for my education only to graduate and spend several more years training rigorously as a resident! Yet, for a field that demands so much from its members, it offers relatively little opportunity for prospect...
