Real Talk on the Metaphysics of Gender
Gender classifications often are controversial. These controversies typically focus on whether gender classifications align with facts about gender kind membership: Could someone really be nonbinary? Is Chris Mosier really a man? I think this is a bad approach. Consider the possibility of ontological oppression, which arises when social kinds operating in a context unjustly constrain the behaviors, concepts, or affect of certain groups. Gender kinds operating in dominant contexts, I argue, oppress trans and nonbinary persons in this way: they marginalize trans men and women, and exclude nonbinary persons. As a result, facts about membership in dominant gender kinds should not settle gender classification practices
So you want to be a lattice theorist?
For this after dinner talk I intersperse images of real lattices with a
discussion of the motivations for lattice gauge theory and some current
unresolved issues.Comment: 6 pages, 7 figures. After dinner talk at Quark confinement and the
hadron spectrum VII, Ponta Delgada, Azores, Portugal, 2-7 September 200
On the Predictability of Talk Attendance at Academic Conferences
This paper focuses on the prediction of real-world talk attendances at
academic conferences with respect to different influence factors. We study the
predictability of talk attendances using real-world tracked face-to-face
contacts. Furthermore, we investigate and discuss the predictive power of user
interests extracted from the users' previous publications. We apply Hybrid
Rooted PageRank, a state-of-the-art unsupervised machine learning method that
combines information from different sources. Using this method, we analyze and
discuss the predictive power of contact and interest networks separately and in
combination. We find that contact and similarity networks achieve comparable
results, and that combinations of different networks can only to a limited
extend help to improve the prediction quality. For our experiments, we analyze
the predictability of talk attendance at the ACM Conference on Hypertext and
Hypermedia 2011 collected using the conference management system Conferator
GPDs and DVCS with Positrons
The beam charge asymmetry helps to isolate the real part of the deeply
virtual Compton scattering (DVCS) amplitude. It is discussed what information
can be gained both from the real and imaginary part of the DVCS amplitude.Comment: 5 pages, 2 figures, invited talk at `Workshop on Positrons at

A complex path around the sign problem
We review recent attempts at dealing with the sign problem in Monte Carlo
calculations by deforming the region of integration in the path integral from
real to complex fields. We discuss the theoretical foundations, the algorithmic
issues and present some results for low dimensional field theories in both
imaginary and real time.Comment: Write up of the talk delivered al Lattice 201
Comparing the information capacity of entangled Laguerre-Gaussian and Hermite-Gaussian modal sets in a finite-aperture system
Using a spontaneous parametric down-conversion process to create entangled spatial states, we compare the information capacity associated with measurements in the Hermite–Gaussian and Laguerre–Gaussian modal basis in an optical system of finite aperture. We show that the cross-talk imposed by the aperture restriction degrades the information capacity. However, the Laguerre–Gaussian mode measurements show greater resilience to cross talk than the Hermite–Gaussian, suggesting that the Laguerre–Gaussian modal set may still offer real-world advantages over other modal sets
Developments in General Relativity: Black Hole Singularity and Beyond
At the 20-th Texas Symposium on Relativistic Astrophysics there was a plenary
talk devoted to the recent developments in classical Relativity. In that talk
the problems of gravitational collapse, collisions of black holes, and of black
holes as celestial bodies were discussed. But probably the problems of the
internal structure of black holes are a real great challenge. In my talk I want
to outline the recent achievements in our understanding of the nature of the
singularity (and beyond!) inside a realistic rotating black hole. This
presentation also addresses the following questions: Can we see what happens
inside a black hole? Can a falling observer cross the singularity without being
crushed? An answer to these questions is probably "yes".Comment: 13 page
Godot and the New Physics
A survey is made of selected topics in flavour physics where real progress is
expected in the coming half-decade, paying particular attention to those where
New Physics signals may appear.Comment: Invited talk at FPCP 2009, Lake Placid, NY, US
