Bs Physics at CDF and D0
Run II at the Tevatron has seen an explosion of results related to the Bs
meson, ranging from tests of QCD models, to probes of electro-weak symmetry
breaking, to direct searches for new physics effects. I will briefly summarize
the CDF and D0 Bs-physics programs, describing the suitability of the detectors
for doing this kind of physics, and pointing out how our knowledge of important
quantities has improved through Run II measurements.Comment: added Fermilab-Conf number, corrected two misquoted theoretical

Efficient numerical method for computation of thermohydrodynamics of laminar lubricating films
The purpose of this paper is to describe an accurate, yet economical, method for computing temperature effects in laminar lubricating films in two dimensions. The procedure presented here is a sequel to one presented in Leeds in 1986 that was carried out for the one-dimensional case. Because of the marked dependence of lubricant viscosity on temperature, the effect of viscosity variation both across and along a lubricating film can dwarf other deviations from ideal constant-property lubrication. In practice, a thermohydrodynamics program will involve simultaneous solution of the film lubrication problem, together with heat conduction in a solid, complex structure. The extent of computation required makes economy in numerical processing of utmost importance. In pursuit of such economy, we here use techniques similar to those for Gaussian quadrature. We show that, for many purposes, the use of just two properly positioned temperatures (Lobatto points) characterizes well the transverse temperature distribution

Bounds for the logarithm of the Euler gamma function and its derivatives
We consider differences between and truncations of certain
classical asymptotic expansions in inverse powers of whose
coefficients are expressed in terms of Bernoulli polynomials ,
and we obtain conditions under which these differences are strictly completely
monotonic. In the symmetric cases and , we recover
results of Sonin, N\"orlund and Alzer. Also we show how to derive these
asymptotic expansions using the functional equation of the logarithmic
derivative of the Euler gamma function, the representation of as a
difference , and a backward induction.Comment: 15 page
Keep Me Around: Intron Retention Detection and Analysis
We present a tool, keep me around (kma), a suite of python scripts and an R
package that finds retained introns in RNA-Seq experiments and incorporates
biological replicates to reduce the number of false positives when detecting
retention events. kma uses the results of existing quantification tools that
probabilistically assign multi-mapping reads, thus interfacing easily with
transcript quantification pipelines. The data is represented in a convenient,
database style format that allows for easy aggregation across introns, genes,
samples, and conditions to allow for further exploratory analysis
