The T2K Indication of Relatively Large theta_13 and a Natural Perturbation to the Democratic Neutrino Mixing Pattern
The T2K Collaboration has recently reported a remarkable indication of the
\nu_\mu -> \nu_e oscillation which is consistent with a relatively large value
of \theta_{13} in the three-flavor neutrino mixing scheme. We show that it is
possible to account for such a result of \theta_{13} by introducing a natural
perturbation to the democratic neutrino mixing pattern, without or with CP
violation. A testable correlation between \theta_{13} and \theta_{23} is
predicted in this ansatz. We also discuss the Wolfenstein-like parametrization
of neutrino mixing, and comment on other possibilities of generating
sufficiently large \theta_{13} at the electroweak scale.Comment: RevTeX 8 page
Exploring the evidence base for acupuncture in the treatment of Meniere’s Syndrome — A systematic review
Meniere’s syndrome is a long-term, progressive disease that damages the balance and hearing
parts of the inner ear. To address the paucity of information on which evidence-based treatment
decisions should be made, a systematic review of acupuncture for Meniere’s syndrome was
undertaken. The method used was a systematic review of English and Chinese literature, from
six databases for randomized, non-randomized and observational studies. All studies were
critically appraised and a narrative approach to data synthesis was adopted. Twenty-seven
studies were included in this review (9 in English and 18 in Chinese languages): three randomized
controlled trials, three non-randomized controlled studies and four pre-test, post-test
designs. All but one of the studies was conducted in China. The studies covered body acupuncture,
ear acupuncture, scalp acupuncture, fluid acupuncture point injection and moxibustion.
The studies were of varying quality. The weight of evidence, across all study types, is of beneficial
effect from acupuncture, for those in an acute phase or those who have had Meniere’s
syndrome for a number of years. The review reinforces the importance of searching for studies
from English and Chinese literature. The transferability of the findings from China to a
Western context needs confirmation. Further research is also needed to clarify questions
around the appropriate frequency and number of treatment/courses of acupuncture. The
weight of evidence suggests a potential benefit of acupuncture for persons with Meniere’s
disease, including those in an acute phase and reinforces the importance of searching for
published studies in the Chinese language
Price volatility and return on pig fattening under different price- quantity contract regimes
The goal of this study is to estimate how different price or quantity fixing contracts affect the value of pig space unit in pig fattening. The value of pig space unit is estimated with a stochastic dynamic programming algorithm. The model maximises the value of pig space unit by using four decision variables. The input-output ratios are endogenous and the option to suspend production temporarily is taken into account in the model. The results suggests that the smooth functioning of markets in Finland can be promoted by ensuring that price changes are transmitted smoothly between input and output markets, and that producers are compensated for giving up the option to suspend production temporarily in the event if unfavourable market situation. Instead of fixing only the price of output, the contract should aim at reducing the risk associated with gross margin.Demand and Price Analysis, Livestock Production/Industries,

The Majorana Neutrino Mass Matrix with One Texture Zero and One Vanishing Eigenvalue
Possible patterns of the Majorana neutrino mass matrix with one texture
zero and one vanishing eigenvalue are classified and discussed. We find that
three one-zero textures of with and four one-zero textures of
with are compatible with current neutrino oscillation data. The
implications of these phenomenological anstze on the neutrino mass
spectrum and the neutrinoless double beta decay are also explored in some
detail.Comment: RevTex 10 pages (with 2 PS figues). More discussions and references

Factors Influencing the Purchase of Live Seafood in the North Central Region of the United States
This study assesses the preferences of shoppers of live seafood products in the North Central Region of the US accounting for heterogeneity in their preferences. The results suggest that quality assurance considerations and high incomes are factors that would increase the probability of higher expenditures on live fish/shellfish. The purchase of saltwater fish and shellfish also increased the probability of higher expenditures. The North Central Region produces freshwater seafood, and maintaining fish quality through the production process is important to this niche market. Shoppers also purchased live seafood frequently, signifying the importance of availability.Live fish, preferences, random parameters ordered probit, Consumer/Household Economics, Food Consumption/Nutrition/Food Safety, Institutional and Behavioral Economics, Public Economics, Q11, Q21, Q22,
Implications of the KamLAND Measurement on the Lepton Flavor Mixing Matrix and the Neutrino Mass Matrix
We explore some important implications of the KamLAND measurment on the
lepton flavor mixing matrix and the neutrino mass matrix . The
model-independent constraints on nine matrix elements of are obtained to a
reasonable degree of accuracy. We find that nine two-zero textures of are
compatible with current experimental data, but two of them are only marginally
allowed. Instructive predictions are given for the absolute neutrino masses,
Majorana phases of CP violation, effective masses of the tritium beta decay and
neutrinoless double beta decay.Comment: RevTex 15 pages (4 PS figures included
