Observation of electron antineutrino disappearance by the Daya Bay Reactor Neutrino Experiment

This presentation describes a measurement of the neutrino mixing parameter, sin^2(2theta_13), from the Daya Bay Reactor Neutrino Experiment. Disappearance of electron antineutrinos at a distance of ~2 km from a set of six reactors, where the reactor flux is constrained by near detectors, has been clearly observed. The result, based on the ratio of observed to expected rate of antineutrinos, using 139 days of data taken between December 24, 2011 and May 11, 2012, is sin^2(2theta_13) = 0.089 +/- 0.010(stat.) +/- 0.005(syst.). Improvements in sensitivity from inclusion of additional data, spectral analysis, and improved calibration are expected in the future.Comment: Presentation at the DPF 2013 Meeting of the American Physical Society Division of Particles and Fields, Santa Cruz, California, August 13-17, 2013, 6 pages, 2 figure

Worcester's blog – polls hopelessly out of date: a myth?

The blogs are at it again, even letter writers to newspapers. A headline in the Standard the other day caught my eye. “Election polling is too uncertain.” It would, wouldn’t it

ORKA: The Golden Kaon Experiment

ORKA is a proposed experiment to measure the K+ -> pi+ nu nubar branching ratio with 5% precision using the Fermilab Main Injector high intensity proton source. The detector design is based on the BNL E787/E949 experiments, which detected seven candidate events. Two orders of magnitude improvement in sensitivity relative to the BNL experiments comes from enhancements to the beam line and the detector acceptance. Precise measurement of the K+ -> pi+ nu nubar branching ratio with the same level of uncertainty as the well-understood Standard Model prediction allows for sensitivity to new physics at and beyond the LHC mass scale.Comment: 6 pages, 10 figures, Proceedings of BEACH 2012, July 23-28, 2012 in Wichita, K

The Final Measurement of Epsilon'/Epsilon from KTeV

We present precise measurements of CP and CPT symmetry based on the full dataset of K to 2pi decays collected by the KTeV experiment at FNAL. We measure the direct CP violation parameter Re(epsilon'/epsilon) = (19.2 pm 2.1)x10-4. We also report the KL-KS mass difference, the KS lifetime, the phase of epsilon, and the phase difference (phi00)-(phi+-). These results are consistent with other experimental results and with CPT symmetry.Comment: 10 pages, 19 figures. To be published in the proceedings of DPF-2009, Detroit, MI, July 2009, eConf C09072

Travel patterns in ?smart? townsshow potential for traffic reduction

Residents in Darlington,Peterborough and Worcester have a realistic alternative forabout 40-50% of their local car trips, according to recent research.With DfTfunding, these towns are now introducing extensive packages of ?soft? measures toencourage people to choose more sustainable travel options

University-community partnerships: 2006 Worcester speaker series

Over the last decade, partnerships between colleges and universities, government, and businesses have helped foster economic development in the city of Worcester, Massachusetts. In 2006, the Worcester UniverCity Partnership, a coalition of private and public sector organizations working with colleges, in collaboration with the New England Resource Center for Higher Education, organized a speaker series aimed at promoting the depth and impact of university-community partnerships in the city. This report provides highlights from the 2006 Worcester Speaker Series, discusses the history and characteristics of Worcester’s partnerships, and suggests steps toward a workable action agenda for the city. This is a portrait of one city’s approach to strengthening its partnerships, which can also serve as a model for other cities interested in promoting economic development through university-community partnerships. ; Prepared by Marga, Inc. with support from the Federal Reserve Bank of Boston and the Annie E.

TEMPORAL AND SPATIAL DISTRIBUTION OF POACEAE POLLEN IN AREAS OF SOUTHERN UNITED KINGDOM, SPAIN AND PORTUGAL

Overall, longer Poaceae pollen seasons coincided with earlier pollen season start dates. Winter rainfall noticeably affects the intensity of Poaceae pollen seasons in Mediterranean areas, but this was not as important in Worcester. Weekly data from Worcester followed a similar pattern to that of Badajoz and Évora but at a distance of more than 1500 km and 4-5 weeks later
