The CARMENES search for exoplanets around M dwarfs First visual-channel radial-velocity measurements and orbital parameter updates of seven M-dwarf planetary systems

Context. The main goal of the CARMENES survey is to find Earth-mass planets around nearby M-dwarf stars. Seven M dwarfs included in the CARMENES sample had been observed before with HIRES and HARPS and either were reported to have one short period planetary companion (GJ 15 A, GJ 176, GJ 436, GJ 536 and GJ 1148) or are multiple planetary systems (GJ 581 and GJ 876). Aims. We aim to report new precise optical radial velocity measurements for these planet hosts and test the overall capabilities of CARMENES. Methods. We combined our CARMENES precise Doppler measurements with those available from HIRES and HARPS and derived new orbital parameters for the systems. Bona-fide single planet systems were fitted with a Keplerian model. The multiple planet systems were analyzed using a self-consistent dynamical model and their best fit orbits were tested for long-term stability. Results. We confirm or provide supportive arguments for planets around all the investigated stars except for GJ 15 A, for which we find that the post-discovery HIRES data and our CARMENES data do not show a signal at 11.4 days. Although we cannot confirm the super-Earth planet GJ 15 Ab, we show evidence for a possible long-period (P-c = 7030(-630)(+970) d) Saturn-mass (m(c) sin i = 51.8(-5.8)(+5.5) M-circle plus) planet around GJ 15 A. In addition, based on our CARMENES and HIRES data we discover a second planet around GJ 1148, for which we estimate a period P-c = 532.6(-2.5)(+4.1) days, eccentricity e(c) = 0.342(-0.062)(+0.050) and minimum mass m(c) sin i = 68.1(-2.2)(+4.9) M-circle plus. Conclusions. The CARMENES optical radial velocities have similar precision and overall scatter when compared to the Doppler measurements conducted with HARPS and HIRES. We conclude that CARMENES is an instrument that is up to the challenge of discovering rocky planets around low-mass stars
CLIP-115, a novel brain-specific cytoplasmic linker protein, mediates the localization of dendritic lamellar bodies.

Intracellular localization of organelles may depend in part on specific cytoplasmic linker proteins (CLIPs) that link membranous organelles to microtubules. Here, we characterize rat cDNAs encoding a novel, brain-specific CLIP of 115 kDa. This protein contains two N-terminal microtubule-binding domains and a long coiled-coil region; it binds to microtubules and is homologous to CLIP-170, a protein mediating the binding of endosomes to microtubules. CLIP-115 is enriched in the dendritic lamellar body (DLB), a recently discovered organelle predominantly present in bulbous dendritic appendages of neurons linked by dendrodendritic gap junctions. Local microtubule depolymerization leads to a temporary reduction of DLBs. These results suggest that CLIP-115 operates in the control of brain-specific organelle translocations
Evaluation of the XRCC1 gene as a phenotypic modifier in BRCA1/2 mutation carriers. Results from the consortium of investigators of modifiers of BRCA1/BRCA2

Background: Single-nucleotide polymorphisms (SNPs) in genes involved in DNA repair are good candidates to be tested as phenotypic modifiers for carriers of mutations in the high-risk susceptibility genes BRCA1 and BRCA2. The base excision repair (BER) pathway could be particularly interesting given the relation of synthetic lethality that exists between one of the components of the pathway, PARP1, and both BRCA1 and BRCA2. In this study, we have evaluated the XRCC1 gene that participates in the BER pathway, as phenotypic modifier of BRCA1 and BRCA2. Methods: Three common SNPs in the gene, c.-77C>T (rs3213245) p.Arg280His (rs25489) and p.Gln399Arg (rs25487) were analysed in a series of 701 BRCA1 and 576 BRCA2 mutation carriers. Results: An association was observed between p.Arg280His-rs25489 and breast cancer risk for BRCA2 mutation carriers, with rare homozygotes at increased risk relative to common homozygotes (hazard ratio: 22.3, 95% confidence interval: 14.3-34, P<0.001). This association was further tested in a second series of 4480 BRCA1 and 3016 BRCA2 mutation carriers from the Consortium of Investigators of Modifiers of BRCA1 and BRCA2.Conclusions and inteNo evidence of association was found when the larger series was analysed which lead us to conclude that none of the three SNPs are significant modifiers of breast cancer risk for mutation carriers
Comments on Hall transport from effective actions.

We consider parity-odd transport in 2+1 dimensional charged fluids restricting attention to the class of non-dissipative fluids. We show that there is a two parameter family of such non-dissipative fluids which can be derived from an effective action, in contradistinction with a four parameter family that can be derived from an entropy current analysis. The effective action approach allows us to extract the adiabatic transport data, in particular the Hall viscosity and Hall conductivity amongst others, in terms of the thermodynamic functions that enter as ‘coupling constants’. Curiously, we find that Hall viscosity is forced to vanish, whilst the Hall conductivity is generically a non-vanishing function of thermodynamic data determined in terms of the hydrodynamic couplings
MAGIC constraints on gamma-ray emission from Cygnus X-3\ud

Cygnus X-3 is a microquasar consisting of an accreting compact object orbiting around a Wolf-Rayet star. It has been detected at radio frequencies and up to high-energy. rays (above 100 MeV). However, many models also predict a very high energy (VHE) emission (above hundreds of GeV) when the source displays relativistic persistent jets or transient ejections. Therefore, detecting such emission would improve the understanding of the jet physics. The imaging atmospheric Cherenkov telescope MAGIC observed Cygnus X-3 for about 70 hr between 2006 March and 2009 August in different X-ray/radio spectral states and also during a period of enhanced gamma-ray emission. MAGIC found no evidence for a VHE signal from the direction of the microquasar. An upper limit to the integral flux for energies higher than 250 GeV has been set to 2.2 x 10(-12) photons cm(-2) s(-1) (95% confidence level). This is the best limit so far to the VHE emission from this source. The non-detection of a VHE signal during the period of activity in the high-energy band sheds light on the location of the possible VHE radiation favoring the emission from the innermost region of the jets, where absorption is significant. The current and future generations of Cherenkov telescopes may detect a signal under precise spectral conditions.\u
Complete list of Darboux Integrable Chains of the form
  $t_{1x}=t_x+d(t,t_1)$

We study differential-difference equation of the form $$
\frac{d}{dx}t(n+1,x)=f(t(n,x),t(n+1,x),\frac{d}{dx}t(n,x)) $$ with unknown
$t(n,x)$ depending on continuous and discrete variables $x$ and $n$. Equation
of such kind is called Darboux integrable, if there exist two functions $F$ and
$I$ of a finite number of arguments $x$, $\{t(n\pm k,x)\}_{k=-\infty}^\infty$,
${\frac{d^k}{dx^k}t(n,x)}_{k=1}^\infty$, such that $D_xF=0$ and $DI=I$, where
$D_x$ is the operator of total differentiation with respect to $x$, and $D$ is
the shift operator: $Dp(n)=p(n+1)$. Reformulation of Darboux integrability in
terms of finiteness of two characteristic Lie algebras gives an effective tool
for classification of integrable equations. The complete list of Darboux
integrable equations is given in the case when the function $f$ is of the
special form $f(u,v,w)=w+g(u,v)$
A note on the Mordell-Weil rank modulo n

Conjecturally, the parity of the Mordell-Weil rank of an elliptic curve over
a number field K is determined by its root number. The root number is a product
of local root numbers, so the rank modulo 2 is conjecturally the sum over all
places of K of a function of elliptic curves over local fields. This note shows
that there can be no analogue for the rank modulo 3, 4 or 5, or for the rank
itself. In fact, standard conjectures for elliptic curves imply that there is
no analogue modulo n for any n>2, so this is purely a parity phenomenon.Comment: 7 page
Massive graviton propagation of the deformed Ho\v{r}ava-Lifshitz gravity
  without projectability condition

We study graviton propagations of scalar, vector, and tensor modes in the
deformed Ho\v{r}ava-Lifshitz gravity ($\lambda R$-model) without projectability
condition. The quadratic Lagrangian is invariant under diffeomorphism only for
$\lambda=1$ case, which contradicts to the fact that $\lambda$ is irrelevant to
a consistent Hamiltonian approach to the $\lambda R$ model. In this case, as
far as scalar propagations are concerned, there is no essential difference
between deformed Ho\v{r}ava-Lifshitz gravity ($\lambda R$-model) and general
relativity. This implies that there are two degrees of freedom for a massless
graviton without Ho\v{r}ava scalar, and five degrees of freedom appear for a
massive graviton when introducing Lorentz-violating and Fierz-Pauli mass terms.
Finally, it is shown that for $\lambda=1$, the vDVZ discontinuity is absent in
the massless limit of Lorentz-violating mass terms by considering external
source terms.Comment: 21 pages, no figure, version to appear in PL
Herschel-ATLAS: blazars in the SDP field

To investigate the poorly constrained sub-mm counts and spectral properties
of blazars we searched for these in the Herschel-ATLAS (H-ATLAS) science
demostration phase (SDP) survey catalog. We cross-matched 500$\mu$m sources
brighter than 50 mJy with the FIRST radio catalogue. We found two blazars, both
previously known. Our study is among the first blind blazar searches at sub-mm
wavelengths, i.e., in the spectral regime where little is still known about the
blazar SEDs, but where the synchrotron peak of the most luminous blazars is
expected to occur. Our early results are consistent with educated
extrapolations of lower frequency counts and question indications of
substantial spectral curvature downwards and of spectral upturns at mm
wavelengths. One of the two blazars is identified with a Fermi/LAT $\gamma$-ray
source and a WMAP source. The physical parameters of the two blazars are
briefly discussed.These observations demonstrate that the H-ATLAS survey will
provide key information about the physics of blazars and their contribution to
sub-mm counts.Comment: 5 pages, 2 figures, accepted for publication in A&A (Herschel special

The Universal Initial Mass Function In The XUV Disk of M83

We report deep Subaru Halpha observations of the XUV disk of M83. These new
observations enable the first complete census of very young stellar clusters
over the entire XUV disk. Combining Subaru and GALEX data with a stellar
population synthesis model, we find that (1) the standard, but
stochastically-sampled, initial mass function (IMF) is preferred over the
truncated IMF, because there are low mass stellar clusters (10^{2-3}Msun) that
host massive O-type stars; that (2) the standard Salpeter IMF and a simple
aging effect explain the counts of FUV-bright and Halpha-bright clusters with
masses >10^3Msun; and that (3) the Halpha to FUV flux ratio over the XUV disk
supports the standard IMF. The Subaru Prime Focus Camera (Suprime-Cam) covers a
large area even outside the XUV disk -- far beyond the detection limit of the
HI gas. This enables us to statistically separate the stellar clusters in the
disk from background contamination. The new data, model, and previous
spectroscopic studies provide overall consistent results with respect to the
internal dust extinction (Av~0.1 mag) and low metallicity (~0.2Zsun) using the
dust extinction curve of SMC.Comment: 11 pages, 8 figures. Accepted for publication in Ap
Three years of Galileo dust data: II. 1993 to 1995

Between Jan 1993 and Dec 1995 the Galileo spacecraft traversed interplanetary
space between Earth and Jupiter and arrived at Jupiter on 7 Dec 1995. The dust
instrument onboard was operating during most of the time. A relatively constant
impact rate of interplanetary and interstellar (big) particles of 0.4 impacts
per day was detected over the whole three-year time span. In the outer solar
system (outside about 2.6 AU) they are mostly of interstellar origin, whereas
in the inner solar system they are mostly interplanetary particles. Within
about 1.7 AU from Jupiter intense streams of small dust particles were detected
with impact rates of up to 20,000 per day whose impact directions are
compatible with a Jovian origin. Two different populations of dust particles
were detected in the Jovian magnetosphere: small stream particles during
Galileo's approach to the planet and big particles concentrated closer to
Jupiter between the Galilean satellites. There is strong evidence that the dust
stream particles are orders of magnitude smaller in mass and faster than the
instrument's calibration, whereas the calibration is valid for the big
particles. Because the data transmission rate was very low, the complete data
set for only a small fraction (2525) of all detected particles could be
transmitted to Earth; the other particles were only counted. Together with the
358 particles published earlier, information about 2883 particles detected by
the dust instrument during Galileo's six years' journey to Jupiter is now
available.Comment: Accepted for Planetary and Space Science, 37 pages, 5 tables, 13

Noether and some other dynamical symmetries in Kantowski-Sachs model

The forms of coupling of the scalar field with gravity, appearing in the
induced theory of gravity, and the potential are found in the Kantowski-Sachs
model under the assumption that the Lagrangian admits Noether symmetry. The
form thus obtained makes the Lagrangian degenerate. The constrained dynamics
thus evolved due to such degeneracy has been analysed and a solution has also
been presented which is inflationary in behaviour. It has further been shown
that there exists other technique to explore the dynamical symmetries of the
Lagrangian and that is simply by inspecting the field equations. Through this
method, Noether along with some other dynamical symmetries are found, which do
not make the Lagrangian degenerate.Comment: 7 pages,Late
Measurement of the Average Polarization of b Baryons in Hadronic Z^0
  Decays

In the Standard Model, b quarks produced in e^+e^- annihilation at the Z^0
peak have a large average longitudinal polarization of -0.94. Some fraction of
this polarization is expected to be transferred to b-flavored baryons during
hadronization. The average longitudinal polarization of weakly decaying b
baryons, <P_L^{\Lambda_b}>, is measured in approximately 4.3 million hadronic
Z^0 decays collected with the OPAL detector between 1990 and 1995 at LEP. Those
b baryons that decay semileptonically and produce a \Lambda baryon are
identified through the correlation of the baryon number of the \Lambda and the
electric charge of the lepton. In this semileptonic decay, the ratio of the
neutrino energy to the lepton energy is a sensitive polarization observable.
The neutrino energy is estimated using missing energy measurements. From a fit
to the distribution of this ratio, the value
  <P_L^{\Lambda_b}> = -0.56^{+0.20}_{-0.13} +/- 0.09
  is obtained, where the first error is statistical and the second systematic.Comment: 19 pages, LaTeX, 4 eps figures included, submitted to Phys. Lett.
Collinear splitting, parton evolution and the strange-quark asymmetry of
  the nucleon in NNLO QCD

We consider the collinear limit of QCD amplitudes at one-loop order, and
their factorization properties directly in colour space. These results apply to
the multiple collinear limit of an arbitrary number of QCD partons, and are a
basic ingredient in many higher-order computations. In particular, we discuss
the triple collinear limit and its relation to flavour asymmetries in the QCD
evolution of parton densities at three loops. As a phenomenological consequence
of this new effect, and of the fact that the nucleon has non-vanishing quark
valence densities, we study the perturbative generation of a
strange--antistrange asymmetry $s(x)-\bar{s}(x)$ in the nucleon's sea.Comment: 5 pages, 3 figures. Presented at Loops and Legs in Quantum Field

Static correlations functions and domain walls in glass-forming liquids:
  the case of a sandwich geometry

The problem of measuring nontrivial static correlations in deeply supercooled
liquids made recently some progress thanks to the introduction of amorphous
boundary conditions, in which a set of free particles is subject to the effect
of a different set of particles frozen into their (low temperature) equilibrium
positions. In this way, one can study the crossover from nonergodic to ergodic
phase, as the size of the free region grows and the effect of the confinement
fades. Such crossover defines the so-called point-to-set correlation length,
which has been measured in a spherical geometry, or cavity. Here, we make
further progress in the study ofcorrelations under amorphous boundary
conditions by analyzing the equilibrium properties of a glass-forming liquid,
confined in a planar ("sandwich") geometry. The mobile particles are subject to
amorphous boundary conditions with the particles in the surrounding walls
frozen into their low temperature equilibrium configurations. Compared to the
cavity, the sandwich geometry has three main advantages: i) the width of the
sandwich is decoupled from its longitudinal size, making the thermodynamic
limit possible; ii) for very large width, the behaviour off a single wall can
be studied; iii) we can use "anti-parallel" boundary conditions to force a
domain wall and measure its excess energy. Our results confirm that amorphous
boundary conditions are indeed a very useful new tool inthe study of static
properties of glass-forming liquids, but also raise some warning about the fact
that not all correlation functions that can be calculated in this framework
give the same qualitative results.Comment: Submited to JCP special issue on the glass transisio
Revealing the cold dust in low-metallicity environments: I - Photometry
  analysis of the Dwarf Galaxy Survey with Herschel

We present new photometric data from our Herschel Key Programme, the Dwarf
Galaxy Survey (DGS), dedicated to the observation of the gas and dust in 48
low-metallicity environments. They were observed with PACS and SPIRE onboard
Herschel at 70,100,160,250,350, and 500 microns. We focus on a systematic
comparison of the derived FIR properties (FIR luminosity, dust mass, dust
temperature and emissivity index) with more metal-rich galaxies and investigate
the detection of a potential submm excess. The data reduction method is adapted
for each galaxy to derive the most reliable photometry from the final maps.
PACS flux densities are compared with the MIPS 70 and 160 microns bands. We use
colour-colour diagrams and modified blackbody fitting procedures to determine
the dust properties of the DGS galaxies. We also include galaxies from the
Herschel KINGFISH sample, containing more metal-rich environments, totalling
109 galaxies. The location of the DGS galaxies on Herschel colour-colour
diagrams highlights the differences in global environments of low-metallicity
galaxies. The dust in DGS galaxies is generally warmer than in KINGFISH
galaxies (T_DGS~32 K, T_KINGFISH~23 K). The emissivity index, beta, is ~1.7 in
the DGS, but metallicity does not make a strong effect on beta. The
dust-to-stellar mass ratio is lower in low-metallicity galaxies:
M_dust/M_star~0.02% for the DGS vs 0.1% for KINGFISH. Per unit dust mass, dwarf
galaxies emit ~6 times more in the FIR than higher metallicity galaxies. Out of
the 22 DGS galaxies detected at 500 micron, 41% present an excess in the submm
not explained by our dust SED model. The excess mainly appears in lower
metallicity galaxies (12+log(O/H) < 8.3), and the strongest excesses are
detected in the most metal-poor galaxies. We stress the need for observations
longwards of the Herschel wavelengths to detect any submm excess appearing
beyond 500 micron.Comment: 32 pages, 20 figures, accepted in A&
Displaced vertices and long-lived charged particles in the NMSSM with
  right-handed sneutrinos

We study LHC signatures of displaced vertices and long-lived charged
particles within the context of the Next-to-Minimal Supersymmetric Standard
Model with right-handed (RH) sneutrinos. In this construction the RH neutrino
can be produced directly from Higgs decays or in association with a RH
sneutrino when the latter is the lightest supersymmetric particle. The RH
neutrino is generally long-lived, since its decay width is proportional to the
neutrino Yukawa, a parameter which is predicted to be small. The RH neutrino
late decay can therefore give rise to displaced vertices at the LHC, which can
be identified through the decay products, which involve two leptons (2l+ MET)
or a lepton with two jets (ljj). We simulate this signal for the current LHC
configuration (a centre of mass of 8 TeV and an integrated luminosity of L=20
fb^-1), and a future one (13 TeV and L=100 fb^-1). We show that a region of the
parameter space of this model can be probed and that the RH neutrino mass can
be reconstructed from the end-point of the two-lepton invariant mass
distribution or the central value of the mass distribution for two jets plus
one lepton. Another exotic signature of this construction is the production of
a long-lived stau. If the stau is the next-to-lightest supersymmetric particle,
it can decay through diagrams involving the small neutrino Yukawa, and would
escape the detector leaving a characteristic trail. We also simulate this
signal for various benchmark points and show that the model can be within the
reach of the future run of the LHC.Comment: 31 pages, 11 figures. Table 1 enlarged. Comments added. Matches with

Unveiling the Structure of Barred Galaxies at 3.6 $\mu {\rm m}$ with the
  Spitzer Survey of Stellar Structure in Galaxies (S$^4$G): I. Disk Breaks

We have performed two-dimensional multicomponent decomposition of 144 local
barred spiral galaxies using 3.6 $\mu {\rm m}$ images from the Spitzer Survey
of Stellar Structure in Galaxies. Our model fit includes up to four components
(bulge, disk, bar, and a point source) and, most importantly, takes into
account disk breaks. We find that ignoring the disk break and using a single
disk scale length in the model fit for Type II (down-bending) disk galaxies can
lead to differences of 40% in the disk scale length, 10% in bulge-to-total
luminosity ratio (B/T), and 25% in bar-to-total luminosity ratios. We find that
for galaxies with B/T $\geq$ 0.1, the break radius to bar radius, $r_{\rm
br}/R_{\rm bar}$, varies between 1 and 3, but as a function of B/T the ratio
remains roughly constant. This suggests that in bulge-dominated galaxies the
disk break is likely related to the outer Lindblad Resonance (OLR) of the bar,
and thus moves outwards as the bar grows. For galaxies with small bulges, B/T
$<$ 0.1, $r_{\rm br}/R_{\rm bar}$ spans a wide range from 1 to 6. This suggests
that the mechanism that produces the break in these galaxies may be different
from that in galaxies with more massive bulges. Consistent with previous
studies, we conclude that disk breaks in galaxies with small bulges may
originate from bar resonances that may be also coupled with the spiral arms, or
be related to star formation thresholds.Comment: Accepted for publication in ApJ, 21 pages, 13 figures, 2 table
