Thirty-two Goldbach Variations
We give thirty-two diverse proofs of a small mathematical gem--the
fundamental Euler sum identity zeta(2,1)=zeta(3) =8zeta(\bar 2,1). We also
discuss various generalizations for multiple harmonic (Euler) sums and some of
their many connections, thereby illustrating both the wide variety of
techniques fruitfully used to study such sums and the attraction of their
study.Comment: v1: 34 pages AMSLaTeX. v2: 41 pages AMSLaTeX. New introductory
material added and material on inequalities, Hilbert matrix and Witten zeta
functions. Errors in the second section on Complex Line Integrals are
corrected. To appear in International Journal of Number Theory. Title change

Bollinger Bands Thirty Years Later
The goal of this study is to explain and examine the statistical
underpinnings of the Bollinger Band methodology. We start off by elucidating
the rolling regression time series model and deriving its explicit relationship
to Bollinger Bands. Next we illustrate the use of Bollinger Bands in pairs
trading and prove the existence of a specific return duration relationship in
Bollinger Band pairs trading.Then by viewing the Bollinger Band moving average
as an approximation to the random walk plus noise (RWPN) time series model, we
develop a pairs trading variant that we call "Fixed Forecast Maximum Duration'
Bands" (FFMDPT). Lastly, we conduct pairs trading simulations using SAP and
Nikkei index data in order to compare the performance of the variant with
Bollinger Bands
Thirty-Three Stata Tips
Since 2003, the Stata Journal has published Stata Tips on special issues in data analysis with Stata. Now Thirty-three Stata Tips compiles these useful guides into a compact tome for ease of reference. In keeping with the Stata spirit, Tips are from Stata users and StataCorp employees alike and will serve as guideposts for both new and experienced users.data management, statistics, graphics, Stata
Thirty Years of Turnstiles and Transport
To characterize transport in a deterministic dynamical system is to compute
exit time distributions from regions or transition time distributions between
regions in phase space. This paper surveys the considerable progress on this
problem over the past thirty years. Primary measures of transport for
volume-preserving maps include the exiting and incoming fluxes to a region. For
area-preserving maps, transport is impeded by curves formed from invariant
manifolds that form partial barriers, e.g., stable and unstable manifolds
bounding a resonance zone or cantori, the remnants of destroyed invariant tori.
When the map is exact volume preserving, a Lagrangian differential form can be
used to reduce the computation of fluxes to finding a difference between the
action of certain key orbits, such as homoclinic orbits to a saddle or to a
cantorus. Given a partition of phase space into regions bounded by partial
barriers, a Markov tree model of transport explains key observations, such as
the algebraic decay of exit and recurrence distributions.Comment: Updated and corrected versio
Thirty Years of Precision Electroweak Physics
We discuss the development of the theory of electroweak radiative corrections
and its role in testing the Standard Model, predicting the top quark mass,
constraining the Higgs boson mass, and searching for deviations that may signal
the presence of new physics.Comment: 19 pages, acknowledgments added, J.J.Sakurai Prize Talk, APS Meeting,

Thirty New Low-Mass Spectroscopic Binaries
As part of our search for young M dwarfs within 25 pc, we acquired
high-resolution spectra of 185 low-mass stars compiled by the NStars project
that have strong X-ray emission. By cross-correlating these spectra with radial
velocity standard stars, we are sensitive to finding multi-lined spectroscopic
binaries. We find a low-mass spectroscopic binary fraction of 16% consisting of
27 SB2s, 2 SB3s and 1 SB4, increasing the number of known low-mass SBs by 50%
and proving that strong X-ray emission is an extremely efficient way to find
M-dwarf SBs. WASP photometry of 23 of these systems revealed two low-mass EBs,
bringing the count of known M dwarf EBs to 15. BD -22 5866, the SB4, is fully
described in Shkolnik et al. 2008 and CCDM J04404+3127 B consists of a two
mid-M stars orbiting each other every 2.048 days. WASP also provided rotation
periods for 12 systems, and in the cases where the synchronization time scales
are short, we used P_rot to determine the true orbital parameters. For those
with no P_rot, we use differential radial velocities to set upper limits on
orbital periods and semi-major axes. More than half of our sample has
near-equal-mass components (q > 0.8). This is expected since our sample is
biased towards tight orbits where saturated X-ray emission is due to tidal
spin-up rather than stellar youth. Increasing the samples of M dwarf SBs and
EBs is extremely valuable in setting constraints on current theories of stellar
multiplicity and evolution scenarios for low-mass multiple systems.Comment: Accepted to Ap
A Thirty-Four Billion Solar Mass Black Hole in SMSS J2157-3602, the Most Luminous Known Quasar
From near-infrared spectroscopic measurements of the MgII emission line
doublet, we estimate the black hole (BH) mass of the quasar, SMSS
J215728.21-360215.1, as being (3.4 +/- 0.6) x 10^10 M_sun and refine the
redshift of the quasar to be z=4.692. SMSS J2157 is the most luminous known
quasar, with a 3000A luminosity of (4.7 +/- 0.5) x 10^47 erg/s and an estimated
bolometric luminosity of 1.6 x 10^48 erg/s, yet its Eddington ratio is only
~0.4. Thus, the high luminosity of this quasar is a consequence of its
extremely large BH -- one of the most massive BHs at z > 4.Comment: 7 pages, 3 figures. Accepted for publication in MNRA
