Data analysis for professors. Simple (you have got to be kidding!) steps and examples to get the rest of us started.
 

Limits on the Two Higgs Doublet Model from meson decay, mixing and CP violation. (With Carlos A. Marin. See final version in http://www.slac.stanford.edu/spires/hep/ .)
 

MCM II and the Trip chip.
 

D0 solenoid magnetic field measurements.
 

Design of the new MCM. The MCM's amplify the VLPC signals from the Central Fiber Tracker and Preshower detectors. These modules will have to be replaced for operation at 132 ns bunch crossing. We describe the design of the new MCM's. (With Paul Rubinov.)
 

Find_Jpsi_Ks. Documentation for the 'Find_Jpsi_Ks' software that finds tracks and track pairs originating from a common vertex using the D0 Fiber Tracker.
 

Power series expansion of the solenoid magnetic field. Developes a power series expansion for the magnetic field inside the D0 solenoid.
 

User's guide for the solenoid magnetic field software. Describes an automated procedure that starts with the measured magnetic field, obtains the parameters of the magnetic field power series expansion, and then obtains the magnetic field look-up table. Software is provided that returns the magnetic field inside the D0 solenoid in 1 micro-second using this look-up table. (With Fausto Pasmay.)
 

Real-time data processing in the Run II Muon System of the D0 detector.
 

Measurement of the like-sign dimuon charge asymmetry in pp-bar collisions at sqrt s= 1.8 TeV. Describes a curious observation that no one believes. Unpublished. Compare with the expectations of the Standard Model: Like-sign dimuon charge asymmetry in the decay of BB-bar pairs. (With Carlos Marin.)
 

Measurement of VLPC saturation. D0 note 3889. (With Don Lincoln.)
 

Measurement of VLPC quantum efficiency. D0 note 3889. (With Don Lincoln.)
 

Evaluation of the SIFT chip discriminator for operation at 132ns. The SIFT chip takes VLPC signals from the fiber tracker or the preshower detector and produces two outputs per channel: a digital trigger output, and an analog output sent to a SVX chip for analog-to-digital conversion. The study shows that the present SIFT chip will not meet the D0 detector requirements when bunch crossing becomes 132ns. (With Paul Rubinov.)
 

Replace the SIFT, MCM or AFE? Design of a "new SIFT" chip. The SIFT chip will have to be replaced when the bunch crossing time becomes 132ns. Can we replace the SIFT chips only, or will we have to replace the entire MCM modules or even the AFE boards? To help answer this question, we have made a preliminary design of a "new SIFT" chip. We then discuss options. (With Paul Rubinov.)
 

Three generation neutrino mixing is compatible with all experiments. We consider the minimal extension of the Standard Model with three generations of massive neutrinos that mix. We then determine the parameters of the model that satisfy all experimental constraints. (With Carlos Marin.)
 

Shopping list for Run II. A "brain storm" on what we can do in Run II of D0.
 

A simple model of the hierarchical formation of galaxies We develop a simple, fast and predictive model of the hierarchical formation of galaxies which is in quantitative agreement with observations. Comparing simulations with observations we place constraints on the density of the universe and on the power spectrum of density fluctuations.
 

What future does the universe have? We discuss the future evolution of the universe in the light of recent observations.
 

Global warming: What does the data tell us? We present the analysis of data obtained at 13472 weather stations since 1702. (With Eduardo Alban.)
 

A model of memory, learning and recognition We propose a simple model of recognition, short-term memory, long-term memory and learning.
 

Para que tener sexo? We discuss the advantages of sexual reproduction in the evolution of multi-cellular organisms. We propose that an echological niche can attract evolution to itself and we explain how. (In Spanish.)
 

Interesting physics highlights.
