Reactor Fuel Fraction Information on the Antineutrino Anomaly
We analyzed the evolution data of the Daya Bay reactor neutrino experiment in
terms of short-baseline active-sterile neutrino oscillations taking into
account the theoretical uncertainties of the reactor antineutrino fluxes. We
found that oscillations are disfavored at with respect to a
suppression of the reactor antineutrino flux and at
with respect to variations of the and
fluxes. On the other hand, the analysis of the rates of the
short-baseline reactor neutrino experiments favor active-sterile neutrino
oscillations and disfavor the suppression of the flux at
and variations of the and fluxes
at . We also found that both the Daya Bay evolution data and the
global rate data are well-fitted with composite hypotheses including variations
of the or fluxes in addition to
active-sterile neutrino oscillations. A combined analysis of the Daya Bay
evolution data and the global rate data shows a slight preference for
oscillations with respect to variations of the and
fluxes. However, the best fits of the combined data are given
by the composite models, with a preference for the model with an enhancement of
the flux and relatively large oscillations.Comment: 9 page
Evolution of the Reactor Antineutrino Flux and Spectrum at Daya Bay
The Daya Bay experiment has observed correlations between reactor core fuel
evolution and changes in the reactor antineutrino flux and energy spectrum.
Four antineutrino detectors in two experimental halls were used to identify 2.2
million inverse beta decays (IBDs) over 1230 days spanning multiple fuel cycles
for each of six 2.9 GW reactor cores at the Daya Bay and Ling
Ao nuclear power plants. Using detector data spanning effective Pu
fission fractions, , from 0.25 to 0.35, Daya Bay measures an average
IBD yield, , of
cm/fission and a fuel-dependent variation in the IBD yield,
, of cm/fission.
This observation rejects the hypothesis of a constant antineutrino flux as a
function of the Pu fission fraction at 10 standard deviations. The
variation in IBD yield was found to be energy-dependent, rejecting the
hypothesis of a constant antineutrino energy spectrum at 5.1 standard
deviations. While measurements of the evolution in the IBD spectrum show
general agreement with predictions from recent reactor models, the measured
evolution in total IBD yield disagrees with recent predictions at 3.1.
This discrepancy indicates that an overall deficit in measured flux with
respect to predictions does not result from equal fractional deficits from the
primary fission isotopes U, Pu, U, and Pu.
Based on measured IBD yield variations, yields of and cm/fission have been determined for the two
dominant fission parent isotopes U and Pu. A 7.8% discrepancy
between the observed and predicted U yield suggests that this isotope
may be the primary contributor to the reactor antineutrino anomaly.Comment: 7 pages, 5 figure

A STUDY ON THE THEMES, MEANING, AND MESSAGE, IN MADONNA’S SONG“ DON’T CRY FOR ME ARGENTINA” BASED ON “EVITA” SOUNDTRACK
Literary work, manifested in its various forms such as a short story, novels, drama, and poetry, represents the condition and historical moments existing in the region, country, and world. Literary work plays a role to reveal the truth through their language and symbols behind the works. Song, a lyrical poetry is a representative of music, which can transmit ideas and emotions to its listeners. Madonna, as a singer from Bay City, Michigan with her concerns attempted to imply the ideas through the songs she sung and brought the listeners to the events inspiring her in writing the songs. The three major purpose considered being the main problems in analyzing Madonna's song were to: (1) Finding Out the Themes of Madonna song, (2) Figuring Out the meaning expressed by author, and (3) Describin" the message inspiring the son" writing The study uses a descriptive qualitative research design to analyze the data. The approaches that were suitable with thesis analysis were objective and historical approaches. The objective approach was used because the objects as a part of the research, are themes, meaning and message in Madonna's song. The historical approach was used to find basic clues related to the events behind the lyrics writing in the current times. Here, one song was selected. The song is: Don't Cry For Me gentina. The results of this study were: the theme of die song based on "Evita" soundtrack was the struggle. The message conveyed in the song was: the success of the woman to save citizen and the nation from the poverty and starvation in Argentina so she was a Noble as number 1 woman in Argentina. The meaning based on soundtrack that lied behind the song writing was the disturbance and demonstration that occurred at Argentina in 1943
Event detection based on generic characteristics of field-sports
In this paper, we propose a generic framework for event detection in broadcast video of multiple different field-sports. Features indicating significant events are selected, and robust detectors built. These features are rooted in generic characteristics common to all genres of field-sports. The evidence gathered by the feature detectors is combined by means of a support vector machine, which infers the occurrence of an event based on a model generated during a training phase. The system is tested across multiple genres of field-sports including soccer, rugby, hockey and Gaelic football and the results suggest that high event retrieval and content rejection statistics are achievable

Why do we invest ethically?
Analysis in this paper has proposed three potential motives for ethical investment - financial returns, non-wealth returns and social change. The motives are developed from
the literature and illustrated in the context of a 'best of sector' fund and a socially screened fund. We find that the proposed motives are neither exhaustive nor exclusive and one single motive will not explain the behaviour of all ethical investors. There may be a trade-off between financial and psychic returns for some investors. The trade-off for consumption-investors is expected to be close to zero (total utility is maximised with small levels of ethical investment in the fun of participation model) and is expected to vary with the ethical intensity of investment-investors, as shown when we include ethical
intensity into the investor's utility function. Psychic return can also be viewed as an increase in happiness and this approach would lend itself to empirical testing to increase our understanding of why we invest ethically
