Early b physics at CMS
The CMS experiment at the Large Hadron Collider collected in the first months
of operation a luminosity of about 300/nb. The first results in the context of
the B physics obtained with these data are presented. The di-muon resonances
from J/psi and Y decays are presented and their total and differential
cross-sections measured. The inclusive B production have also being
investigated and two independent measurements are reported. Muons in jets are
used as a way to identify events with B content, the kinematic properties
(ptRel) of the muons are used to separate the B production from other processes
producing muons in jets. The second measurement of inclusive B production is
done using b-tagging techniques and higher energy jets. The two measurements
cover different phase spaces, comparison with LO and NLO prediction are also
presented.Comment: HCP2010 proceedings. CMS CR-2010/19
Evaluation of the gn-->pi-p differential cross sections in the Delta-isobar region
Differential cross sections for the process gn-->pi-p have been extracted
from MAMI-B measurements of gd-->pi-pp, accounting for final-state interaction
effects, using a diagrammatic technique taking into account the NN and piN
final-state interaction amplitudes. Results are compared to previous
measurements of the inverse process, pi-p--> ng, and recent multipole analyses.Comment: 6 pages, 4 figures. v2: Further clarifications and minor changes. A

Strong anonymity and infinite streams.
The extended rank-discounted utilitarian social welfare order introduced and axiomatized by Stéphane Zuber and Geir B. Asheim satisfies strong anonymity (J. Econ. Theory (2011), doi:10.1016/j.jet.2011.08.001). We question the appropriateness of strong anonymity in the context of a countably infinite sequence of subsequent generations. A modified criterion that is incomplete and satisfies finite anonymity is presented.
Effect of the E3 Fitness Grips on Running Economy
Int J Exerc Sci 3(2) : 64-67, 2010. The purpose of this study was to evaluate the effect of the E3 Fitness Grips (BioGrip, Inc., Rancho Cordova, CA) on running economy, as measured by oxygen uptake (VO2), and heart rate (HR) during submaximal treadmill running. Eleven subjects, seven female and four male, completed a submaximal running test on a treadmill while VO2 and HR were measured continuously. After achieving steady-state at a speed and grade that elicited a VO2 equivalent to 70% VO2max, the subjects ran for five minutes holding the E3 Fitness Grips (G) and five minutes without the grips (NG). The tests were counterbalanced so half of the subjects held the grips first and half completed the NG condition first. The difference in VO2 and HR between the G and NG conditions were compared to determine the effect on running economy. The mean VO2 (33.2±4.6 vs. 33.2±4.6 ml⋅kg-1⋅min-1, p=0.96) and mean HR (172.0±8.9 vs. 172.8±8.9 beats⋅min-1, p=0.38) were not significantly different between the G and NG conditions during submaximal running. These findings suggest that the E3 Fitness Grips do not significantly alter running economy, as measured by VO2, or HR during submaximal treadmill running
