Not left behind? Five questions that need answering before the Copeland and Stoke by-elections
There will be two by-elections this month, yet the focus is more on who will win than on what policies they will adopt if they do win. Peter Kenway, Dan Corry, and Steve Barwick outline the main problems facing Stoke and Copeland, and set some key questions that will make for a more substantive debate
Building Back Health and Prosperity Report of the Health Devolution Commission
The Covid-19 pandemic has had a far-reaching and profound impact on the future of our health, social care, public health and economic landscape. The pandemic has had a disproportionate impact on economically disadvantaged and Black, Asian and Minority Ethnic communities. People living with particular conditions such as cancer, mental ill-health and dementia have been badly affected. Health inequalities are worsening, NHS and social care services are deeply divided, demand for care is increasing, the capacity of the system to respond is weaker, community institutions are struggling, and the prospects for the economy and jobs is alarming. If ever there was a compelling ‘burning deck’ of circumstances that requires an urgent and radical response it is now. We must not only integrate our NHS and social care services but also relocate the NHS within a new and comprehensive framework for rebuilding the health and prosperity of our communities and our nation
ESTIMATING RETURNS FROM PAST INVESTMENTS INTO BEEF CATTLE GENETICS RD&E IN AUSTRALIA
This study aimed at estimating the costs and benefits of all beef cattle genetic improvement activity, across Australia, over the period 1970 to the present. The total cumulative Present Value (PV) of investments by industry, government and other agencies into selection, crossbreeding and grading up since 1963, and of imported genetics, was estimated to be 2001 at a 7% discount rate). Using a suite of genetic evaluation models, farming systems models and an industry-level model, the cumulative PV of industry returns were estimated. Within-breed selection generated 255m; changing breed composition in southern Australia 8.1bn. The benefit/cost ratio for this investment was 28:1 over the last 30 years.Livestock Production/Industries, Research and Development/Tech Change/Emerging Technologies,

A prototype station for ARIANNA: a detector for cosmic neutrinos
The Antarctic Ross Iceshelf Antenna Neutrino Array (ARIANNA) is a proposed
detector for ultra-high energy astrophysical neutrinos. It will detect coherent
radio Cherenkov emission from the particle showers produced by neutrinos with
energies above about 10^17 eV. ARIANNA will be built on the Ross Ice Shelf just
off the coast of Antarctica, where it will eventually cover about 900 km^2 in
surface area. There, the ice-water interface below the shelf reflects radio
waves, giving ARIANNA sensitivity to downward going neutrinos and improving its
sensitivity to horizontally incident neutrinos. ARIANNA detector stations will
each contain 4-8 antennas which search for brief pulses of 50 MHz to 1 GHz
radio emission from neutrino interactions.
We describe a prototype station for ARIANNA which was deployed in Moore's Bay
on the Ross Ice Shelf in December 2009, discuss the design and deployment, and
present some initial figures on performance. The ice shelf thickness was
measured to be 572 +/- 6 m at the deployment site.Comment: 15 pages with 5 figure
APS Neutrino Study: Report of the Neutrino Astrophysics and Cosmology Working Group
In 2002, Ray Davis and Masatoshi Koshiba were awarded the Nobel Prize in
Physics ``for pioneering contributions to astrophysics, in particular for the
detection of cosmic neutrinos.'' However, while astronomy has undergone a
revolution in understanding by synthesizing data taken at many wavelengths, the
universe has only barely been glimpsed in neutrinos, just the Sun and the
nearby SN 1987A. An entire universe awaits, and since neutrinos can probe
astrophysical objects at densities, energies, and distances that are otherwise
inaccessible, the results are expected to be particularly exciting. Similarly,
the revolution in quantitative cosmology has heightened the need for very
precise tests that depend on the effects of neutrinos, and prominent among them
is the search for the effects of neutrino mass, since neutrinos are a small but
known component of the dark matter. In this report, we highlight some of the
key opportunties for progress in neutrino astrophysics and cosmology, and the
implications for other areas of physics
Body Temperature Monitoring and SARS Fever Hotline, Taiwan
In Taiwan, a temperature-monitoring campaign and hotline for severe acute respiratory syndrome (SARS) fever were implemented in June 2003. Among 1,966 calls, fever was recorded in 19% (n = 378); 18 persons at high risk for SARS were identified. In a cross-sectional telephone survey, 95% (n = 1,060) of households knew about the campaign and 7 households reported fever
In-situ estimation of ice crystal properties at the South Pole using LED calibration data from the IceCube Neutrino Observatory
The IceCube Neutrino Observatory instruments about 1 km3 of deep, glacial ice at the geographic South Pole using 5160 photomultipliers to detect Cherenkov light emitted by charged relativistic particles. A unexpected light propagation effect observed by the experiment is an anisotropic attenuation, which is aligned with the local flow direction of the ice. Birefringent light propagation has been examined as a possible explanation for this effect. The predictions of a first-principles birefringence model developed for this purpose, in particular curved light trajectories resulting from asymmetric diffusion, provide a qualitatively good match to the main features of the data. This in turn allows us to deduce ice crystal properties. Since the wavelength of the detected light is short compared to the crystal size, these crystal properties do not only include the crystal orientation fabric, but also the average crystal size and shape, as a function of depth. By adding small empirical corrections to this first-principles model, a quantitatively accurate description of the optical properties of the IceCube glacial ice is obtained. In this paper, we present the experimental signature of ice optical anisotropy observed in IceCube LED calibration data, the theory and parametrization of the birefringence effect, the fitting procedures of these parameterizations to experimental data as well as the inferred crystal properties.</p
TXS 0506+056 with Updated IceCube Data
Past results from the IceCube Collaboration have suggested that the blazar TXS 0506+056 is a potential source of astrophysical neutrinos. However, in the years since there have been numerous updates to event processing and reconstruction, as well as improvements to the statistical methods used to search for astrophysical neutrino sources. These improvements in combination with additional years of data have resulted in the identification of NGC 1068 as a second neutrino source candidate. This talk will re-examine time-dependent neutrino emission from TXS 0506+056 using the most recent northern-sky data sample that was used in the analysis of NGC 1068. The results of using this updated data sample to obtain a significance and flux fit for the 2014 TXS 0506+056 "untriggered" neutrino flare are reported
