Bose-Fermi Degeneracies in Large $N$ Adjoint QCD

We analyze the large $N$ limit of adjoint QCD, an $SU(N)$ gauge theory with
$N_f$ flavors of massless adjoint Majorana fermions, compactified on $S^3
\times S^1$. We focus on the weakly-coupled confining small-$S^3$ regime. If
the fermions are given periodic boundary conditions on $S^1$, we show that
there are large cancellations between bosonic and fermionic contributions to
the twisted partition function. These cancellations follow a pattern previously
seen in the context of misaligned supersymmetry, and lead to the absence of
Hagedorn instabilities for any $S^1$ size $L$, even though the bosonic and
fermionic densities of states both have Hagedorn growth. Adjoint QCD stays in
the confining phase for any $L \sim N^0$, explaining how it is able to enjoy
large $N$ volume independence for any $L$. The large $N$ boson-fermion
cancellations take place in a setting where adjoint QCD is manifestly
non-supersymmetric at any finite $N$, and are consistent with the recent
conjecture that adjoint QCD has emergent fermionic symmetries in the large $N$
limit.Comment: 35 pages, 5 figures. v3: further minor correction
Status of the MSW Solutions to the Solar Neutrino Problem

We present an updated global analysis of two-flavor MSW solutions to the
solar neutrino problem in terms of conversions of nu_e into active or sterile
neutrinos. We perform a fit to the full data set corresponding to the 825-day
Super-Kamiokande data sample as well as to Chlorine, GALLEX and SAGE
experiments. We use all measured total event rates as well as Super-Kamiokande
data on the zenith angle dependence, energy spectrum and seasonal variation of
the events. For conversions into active neutrinos we find that, although the
data on the total event rates favours the Small Mixing Angle (SMA) solution,
once the full data set is included both SMA and Large Mixing Angle (LMA)
solutions give an equivalent fit to the data. The best-fit points for the
combined analysis are Delta m^2=3.6 10^{-5} eV^2 sin^2(2theta)=0.79 with
chi^2_min=35.4/30 d.o.f and Delta m^2=5.1~ 10^{-6} eV^2 and sin^2(2theta)=5.5
10^{-3} with chi^2_min=37.4/30 d.o.f. In contrast with the earlier 504-day
study of Bahcall-Krastev-Smirnov our results indicate that the LMA solution is
not only allowed, but slightly preferred. We also show that seasonal effects,
although small, may still reach 8.5 % at the best-fit LMA solution without
conflict with the hints of a day-night variation (6% is due to the eccentricity
of the Earth's orbit). For conversions into sterile neutrinos only the SMA
solution is allowed with best-fit point Delta m^2=5.0 10^{-6} eV^2 and
sin^2(2theta)=3. 10^{-3} and chi^2_min=40.2/30 d.o.f. We also consider
departures of the Standard Solar Model of Bahcall and Pinsonneault 1998 by
allowing arbitrary 8^B and hep fluxes. Best fit is obtained for
^8B/^8B_SSM=0.61 (1.37) and hep/hep_SSM=12 (38) for the SMA (LMA) solution.Comment: 31 pages ReVTeX, 8 postscript color figures. Updated analysis for 825

$AdS_{3}$/CFT Correspondence, Poincaré vacuum state and Greybody Factors in BTZ Black Holes

The greybody factors in BTZ black holes are evaluated from 2D CFT in the spirit of AdS$_3$/CFT correspondence. The initial state of black holes in the usual calculation of greybody factors by effective CFT is described as Poincaré vacuum state in 2D CFT. The normalization factor which cannot be fixed in the effective CFT without appealing to string theory is shown to be determined by the normalized bulk-to-boundary Green function. The relation among the greybody factors in different dimensional black holes is exhibited. Two kinds of $(h,{\bar h})=(1,1)$ operators which couple with the boundary value of massless scalar field are discussed
The Braiding for Representations of $q$-Deformed Affine $sl_{2}$

We compute the braiding for the `principal gradation' of $U_q(\hat{{\it sl}_2})$ for $|q|=1$ from first principles, starting from the idea of a rigid braided tensor category. It is not necessary to assume either the crossing or the unitarity condition from S-matrix theory. We demonstrate the uniqueness of the normalisation of the braiding under certain analyticity assumptions, and show that its convergence is critically dependent on the number-theoretic properties of the number $\tau$ in the deformation parameter $q=e^{2\pi i\tau}$. We also examine the convergence using probability, assuming a uniform distribution for $q$ on the unit circle
The elliptic gamma function and SL(3,Z) x Z^3

The elliptic gamma function is a generalization of the Euler gamma function
and is associated to an elliptic curve. Its trigonometric and rational
degenerations are the Jackson q-gamma function and the Euler gamma function,
respectively. The elliptic gamma function appears in Baxter's formula for the
free energy of the eight-vertex model and in the hypergeometric solutions of
the elliptic qKZB equations. In this paper, the properties of this function are
studied. In particular we show that elliptic gamma functions are
generalizations of automorphic forms of G=SL(3,Z) x Z^3 associated to a
non-trivial class in H^3(G,Z).Comment: 27 pages, LaTeX References added, minor correction
Search for Narrow NNpi Resonances in Exclusive p p -> p p pi+ pi-
  Measurements

Narrow structures in the range of a few MeV have been searched for in p p pi+
and p p pi- invariant mass spectra obtained from exclusive measurements of the
p p -> p p pi+ pi- reaction at Tp = 725, 750 and 775 MeV using the PROMICE/WASA
detector at CELSIUS. The selected reaction is particularily well suited for the
search for NN and / or N Delta decoupled dibaryon resonances. Except for a
possible fluctuation at 2087 MeV/c^2 in Mpppi- no narrow structures could be
identified neither in Mpppi+ nor in Mpppi- on the 3 sigma level of statistical
significance, giving an upper limit (95% C.L.) for dibaryon production in this
reaction of sigma < 20 nb for 2020 MeV/c^2 < m(dibaryon) < 2085 MeV/c^2Comment: 3 pages, 4 figure
Exclusive Measurements of $pd\to ^3He \pi\pi$ : the $ABC$ Effect
  Revisited

Exclusive measurements of the reactions $pd\to$ $^3He \pi^+ \pi^-$ and
$pd\to$ $^3He \pi^0\pi^0$ have been carried out at $T_p=0.895$ GeV at the
CELSIUS storage ring using the WASA detector. The $\pi^+\pi^-$ channel
evidences a pronounced enhancement at low invariant $\pi\pi$ masses - as
anticipated from previous inclusive measurements of the ABC effect. This
enhancement is seen to be even much larger in the isoscalar $\pi^0\pi^0$
channel. The differential distributions prove this enhancement to be of
scalar-isoscalar nature. $\Delta\Delta$ calculations give a good description of
the data, if a boundstate condition is imposed for the intermediate
$\Delta\Delta$ system.Comment: extended version, 8 pages, 7 figures, theoretical model calculations

The role of the nucleon recoil in low--energy meson--nucleus reactions

The role of the nucleon recoil corrections in low--energy meson--nucleus
interactions is examined. We demonstrate explicitly when calculations within
the static approximation are justified and when the recoil terms need to be
kept explictly in the propagators, depending on whether the S-wave two--nucleon
intermediate state is Pauli blocked or not, while the meson is in flight. While
the effect is studied in detail for $\pi d$ scattering only, a large class of
other reactions is discussed for which the findings are relevant as well.Comment: 10 pages, 1 figure
Realistic two-nucleon potentials for the relativistic two-nucleon
  Schroedinger equation

The potentials $V (v)$ in the nonrelativistic (relativistic) nucleon-nucleon
(NN) Schroedingerequation are related by a quadratic equation. That equation is
numerically solved, thus providing phase equivalent v- potentials related for
instance to the high precision NN potentials, which are adjusted to NN phase
shift and mixing parameters in a nonrelativistic Schroedinger equation. The
relativistic NN potentials embedded in a three-nucleon (3N)system for total NN
momenta different from zero are also constructed in a numerically precise
manner. They enter into the relativistic interacting 3N mass operator, which is
needed for relativistic 3N calculations for bound and scattering states.Comment: 6 pages, 4figures, 2 tables; typos adde
Orbital-Free Molecular Dynamics Simulations of Melting in Na8 and Na20:
  Melting in Steps

The melting-like transitions of Na8 and Na20 are investigated by ab initio
constant energy molecular dynamics simulations, using a variant of the
Car-Parrinello method which employs an explicit electronic kinetic energy
functional of the density, thus avoiding the use of one-particle orbitals.
Several melting indicators are evaluated in order to determine the nature of
the various transitions, and compared with other simulations. Both Na8 and Na20
melt over a wide temperature range. For Na8, a transition is observed to begin
at approx. 110 K, between a rigid phase and a phase involving isomerizations
between the different permutational isomers of the ground state structure. The
``liquid'' phase is completely established at approx. 220 K. For Na20, two
transitions are observed: the first, at approx. 110 K, is associated with
isomerization transitions between those permutational isomers of the ground
state structure which are obtained by interchanging the positions of the
surface-like atoms; the second, at approx. 160 K, involves a structural
transition from the ground state isomer to a new set of isomers with the
surface molten. The cluster is completely ``liquid'' at approx. 220 K.Comment: Revised version, accepted for publication in J. Chem. Phys. The
  changes include longer simulations for the Na20 microcluster, a more complete
  comparison to previous theoretical results, and the discussion of some

Improved Tools for the Brainbow Toolbox

In the transgenic multicolor labeling strategy called 'Brainbow', Cre-loxP recombination is used to create a stochastic choice of expression among fluorescent proteins, resulting in the indelible marking of mouse neurons with multiple distinct colors. This method has been adapted to non-neuronal cells in mice and to neurons in fish and flies, but its full potential has yet to be realized in the mouse brain. Here we present several lines of mice that overcome limitations of the initial lines, and we report an adaptation of the method for use in adeno-associated viral vectors. We also provide technical advice about how best to image Brainbow-expressing tissue.Molecular and Cellular Biolog
Measurement of jet suppression in central Pb-Pb collisions at
  $\sqrt{s_{\rm NN}}$ = 2.76 TeV

The transverse momentum ($p_{\rm T}$) spectrum and nuclear modification
factor ($R_{\rm AA}$) of reconstructed jets in 0-10% and 10-30% central Pb-Pb
collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV were measured. Jets were
reconstructed from charged and neutral particles, utilizing the ALICE tracking
detectors and Electromagnetic Calorimeter (EMCal), with the anti-$k_{\rm T}$
jet algorithm with a resolution parameter of R=0.2. The jet $p_{\rm T}$ spectra
are reported in the pseudorapidity interval of $|{\eta}_{\rm jet}|<0.5$ for
$40<p_{\rm T,jet}<120$ GeV/$c$ in 0-10% and for $30<p_{\rm T,jet}<100$ GeV/$c$
in 10-30% collisions. Reconstructed jets were required to contain a leading
charged particle with $p_{\rm T}>5$ GeV/$c$ to suppress jets constructed from
the combinatorial background in Pb-Pb collisions. The effect of the leading
charged particle requirement has been studied in both pp and Pb-Pb collisions
and has been shown to have negligible effects on the $R_{\rm AA}$ within the
uncertainties of the measurement. The nuclear modification factor is obtained
by dividing the jet spectrum measured in Pb-Pb by that in pp collisions scaled
by the number of independent nucleon-nucleon collisions estimated using a
Glauber model. $R_{\rm AA}$ is found to be $0.28\pm0.04$ in 0-10% and
$0.35\pm0.04$ in 10-30% collisions, independent of $p_{\rm T,jet}$ within the
uncertainties of the measurement. The observed suppression is in fair agreement
with expectations from two model calculations with different approaches to jet
quenching.Comment: 27 pages, 5 captioned figures, 1 table, authors from page 21,

OmegaWINGS: OmegaCAM@VST observations of WINGS galaxy clusters

The Wide-field Nearby Galaxy-cluster Survey (WINGS) is a wide-field
multi-wavelength survey of X-ray selected clusters at z =0.04-0.07. The
original 34'x34' WINGS field-of- view has now been extended to cover a 1 sq.deg
field with both photometry and spectroscopy. In this paper we present the
Johnson B and V-band OmegaCAM/VST observations of 46 WINGS clusters, together
with the data reduction, data quality and Sextractor photometric catalogs.
  With a median seeing of 1arcs in both bands, our 25-minutes exposures in each
band typically reach the 50% completeness level at V=23.1 mag. The quality of
the astrometric and photometric accuracy has been verified by comparison with
the 2MASS as well as with SDSS astrometry, and SDSS and previous WINGS imaging.
Star/galaxy separation and sky-subtraction procedure have been tested comparing
with previous WINGS data.
  The Sextractor photometric catalogues are publicly available at the CDS, and
will be included in the next release of the WINGS database on the VO together
with the OmegaCAM reduced images. These data form the basis for a large ongoing
spectroscopic campaign with AAOmega/AAT and is being employed for a variety of
studies. [abridged]Comment: submitted to A&
Young [$\alpha$/Fe]-enhanced stars discovered by CoRoT and APOGEE: What
  is their origin?

We report the discovery of a group of apparently young CoRoT red-giant stars
exhibiting enhanced [alpha/Fe] abundance ratios (as determined from APOGEE
spectra) with respect to Solar values. Their existence is not explained by
standard chemical evolution models of the Milky Way, and shows that the
chemical-enrichment history of the Galactic disc is more complex. We find
similar stars in previously published samples for which isochrone-ages could be
robustly obtained, although in smaller relative numbers, which could explain
why these stars have not received prior attention. The young [alpha/Fe]-rich
stars are much more numerous in the CoRoT-APOGEE (CoRoGEE) inner-field sample
than in any other high-resolution sample available at present, as only CoRoGEE
can explore the inner-disc regions and provide ages for its field stars. The
kinematic properties of the young [$\alpha$/Fe]-rich stars are not clearly
thick-disc like, despite their rather large distances from the Galactic
mid-plane. Our tentative interpretation of these and previous intriguing
observations in the Milky Way is that these stars were formed close to the end
of the Galactic bar, near corotation -- a region where gas can be kept inert
for longer times, compared to other regions shocked more frequently by the
passage of spiral arms. Moreover, that is where the mass return from older
inner-disc stellar generations should be maximal (according to an inside-out
disc-formation scenario), further diluting the in-situ gas. Other possibilities
to explain these observations (e.g., a recent gas-accretion event) are also
discussed.Comment: Letter in press in Astronomy and Astrophysics (5 pages, 4 figures + 2

The $K \bar K \pi$ decay of the $f_1(1285)$ and its nature as a $K^*
  \bar K -cc$ molecule

We investigate the decay of $f_1(1285) \to \pi K \bar K$ with the assumption
that the $f_1(1285)$ is dynamically generated from the $K^* \bar{K} - cc$
interaction. In addition to the tree level diagrams that proceed via $f_1(1285)
\to K^* \bar{K} - cc \to \pi K \bar K$, we take into account also the final
state interactions of $K \bar K \to K \bar K$ and $\pi K \to \pi K$. The
partial decay width and mass distributions of $f_1(1285) \to \pi K \bar K$ are
evaluated. We get a value for the partial decay width which, within errors, is
in fair agreement with the experimental result. The contribution from the tree
level diagrams is dominant, but the final state interactions have effects in
the mass distributions. The predicted mass distributions are significantly
different from phase space and tied to the $K^* \bar{K} - cc$ nature of the
$f_1(1285)$ state.Comment: Published versio
Feeding interventions for growth and development in infants with cleft lip, cleft palate or cleft lip and palate.

BACKGROUND: Cleft lip and cleft palate are common birth defects, affecting about one baby of every 700 born. Feeding these babies is an immediate concern and there is evidence of delay in growth of children with a cleft as compared to those without clefting. In an effort to combat reduced weight for height, a variety of advice and devices are recommended to aid feeding of babies with clefts. OBJECTIVES: This review aims to assess the effects of these feeding interventions in babies with cleft lip and/or palate on growth, development and parental satisfaction. SEARCH STRATEGY: The following electronic databases were searched: the Cochrane Oral Health Group Trials Register (to 27 October 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 4), MEDLINE via OVID (1950 to 27 October 2010), EMBASE via OVID (1980 to 27 October 2010), PsycINFO via OVID (1950 to 27 October 2010) and CINAHL via EBSCO (1980 to 27 October 2010). Attempts were made to identify both unpublished and ongoing studies. There was no restriction with regard to language of publication. SELECTION CRITERIA: Studies were included if they were randomised controlled trials (RCTs) of feeding interventions for babies born with cleft lip, cleft palate or cleft lip and palate up to the age of 6 months (from term). DATA COLLECTION AND ANALYSIS: Studies were assessed for relevance independently and in duplicate. All studies meeting the inclusion criteria were data extracted and assessed for validity independently by each member of the review team. Authors were contacted for clarification or missing information whenever possible. MAIN RESULTS: Five RCTs with a total of 292 babies, were included in the review. Comparisons made within the RCTs were squeezable versus rigid feeding bottles (two studies), breastfeeding versus spoon-feeding (one study) and maxillary plate versus no plate (two studies). No statistically significant differences were shown for any of the primary outcomes when comparing bottle types, although squeezable bottles were less likely to require modification. No difference was shown for infants fitted with a maxillary plate compared to no plate. However, there was some evidence of an effect on weight at 6 weeks post-surgery in favour of breastfeeding when compared to spoon-feeding (mean difference 0.47; 95% confidence interval 0.20 to 0.74). AUTHORS' CONCLUSIONS: Squeezable bottles appear easier to use than rigid feeding bottles for babies born with clefts of the lip and/or palate, however, there is no evidence of a difference in growth outcomes between the bottle types. There is weak evidence that breastfeeding is better than spoon-feeding following surgery for cleft. There was no evidence to suggest that maxillary plates assist growth in babies with clefts of the palate. No evidence was found to assess the use of any types of maternal advice and/or support for these babies
The future of the northeast Atlantic benthic flora in a high CO2 world

This work was funded by the UK Ocean Acidification Research Programme (cofunded by NERC, Defra, and DECC), NERC OARP Grant: NE/H016996/1 “Ocean Acidification Impacts on Sea-Surface Biogeochemistry and climate”, with additional support from the Marine Biological Association (MBA) and the Natural History Museum.Seaweed and seagrass communities in the northeast Atlantic have been profoundly impacted by humans, and the rate of change is accelerating rapidly due to runaway CO2 emissions and mounting pressures on coastlines associated with human population growth and increased consumption of finite resources. Here, we predict how rapid warming and acidification are likely to affect benthic flora and coastal ecosystems of the northeast Atlantic in this century, based on global evidence from the literature as interpreted by the collective knowledge of the authorship. We predict that warming will kill off kelp forests in the south and that ocean acidification will remove maerl habitat in the north. Seagrasses will proliferate, and associated epiphytes switch from calcified algae to diatoms and filamentous species. Invasive species will thrive in niches liberated by loss of native species and spread via exponential development of artificial marine structures. Combined impacts of seawater warming, ocean acidification, and increased storminess may replace structurally diverse seaweed canopies, with associated calcified and noncalcified flora, with simple habitats dominated by noncalcified, turf-forming seaweeds.Publisher PDFPeer reviewe
CALIFA : a diameter-selected sample for an integral field spectroscopy galaxy survey

JMA acknowledges support from the European Research Council Starting Grant (SEDmorph; P.I. V. Wild).We describe and discuss the selection procedure and statistical properties of the galaxy sample used by the Calar Alto Legacy Integral Field Area (CALIFA) survey, a public legacy survey of 600 galaxies using integral field spectroscopy. The CALIFA "mother sample" was selected from the Sloan Digital Sky Survey (SDSS) DR7 photometric catalogue to include all galaxies with an r-band isophotal major axis between 45 '' and 79 : 2 '' and with a redshift 0 : 005 <z <0 : 03. The mother sample contains 939 objects, 600 of which will be observed in the course of the CALIFA survey. The selection of targets for observations is based solely on visibility and thus keeps the statistical properties of the mother sample. By comparison with a large set of SDSS galaxies, we find that the CALIFA sample is representative of galaxies over a luminosity range of -19 > M-r > -23 : 1 and over a stellar mass range between 10(9.7) and 10(11.4) M-circle dot. In particular, within these ranges, the diameter selection does not lead to any significant bias against - or in favour of - intrinsically large or small galaxies. Only below luminosities of M-r = -19 (or stellar masses <10(9.7) M-circle dot) is there a prevalence of galaxies with larger isophotal sizes, especially of nearly edge-on late-type galaxies, but such galaxies form <10% of the full sample. We estimate volume-corrected distribution functions in luminosities and sizes and show that these are statistically fully compatible with estimates from the full SDSS when accounting for large-scale structure. For full characterization of the sample, we also present a number of value-added quantities determined for the galaxies in the CALIFA sample. These include consistent multi-band photometry based on growth curve analyses; stellar masses; distances and quantities derived from these; morphological classifications; and an overview of available multi-wavelength photometric measurements. We also explore different ways of characterizing the environments of CALIFA galaxies, finding that the sample covers environmental conditions from the field to genuine clusters. We finally consider the expected incidence of active galactic nuclei among CALIFA galaxies given the existing pre-CALIFA data, finding that the final observed CALIFA sample will contain approximately 30 Sey2 galaxies.PostprintPeer reviewe
