Control for Elliptically Polarizing Undulator at SRRC

A Sasaki-type elliptically polarizing undulator (EPU) which will be an important project of insertion device at SRRC is in the construction phase. It can produce an elliptically polarization for advance study in soft X-ray region. The precision of phase is main issue for this control system. The loads of the motor drivers vary with different magnetic force which results from changing the phase ...

Some recent and ongoing research projects

Professor Bialek is interested in a broad set of problems that arise at the interface of physics and biology. His work is animated by the search for principles that might underlie the remarkable functional capabilities of living systems. A theorist, Bialek’s work ranges from abstract theoretical problems to the nitty gritty of experimental design and analysis; he has touched questions which ari...

Polarizing the Dipoles

We extend the massless dipole formalism of Catani and Seymour, as well as its massive version as developed by Catani, Dittmaier, Seymour and Trocsanyi, to arbitrary helicity eigenstates of the external partons. We modify the real radiation subtraction terms only, the primary aim being an improved efficiency of the numerical Monte Carlo integration of this contribution as part of a complete next...

Recommendation Projects at Yahoo!

Recommendation is the task of providing content that is likely to interest users and enrich their online experience. At Yahoo!, the variety of user-facing applications and the nature and volume of data raise multiple recommendation opportunities and challenges. In this paper, we provide a brief description of several projects within Yahoo! Labs, in the context of Web Search (Section 2), interpr...
