Planck 2015 results XXI. The integrated Sachs-Wolfe effect

This paper presents a study of the integrated Sachs-Wolfe (ISW) effect from the Planck 2015 temperature and polarization data release. This secondary cosmic microwave background (CMB) anisotropy caused by the large-scale time-evolving gravitational potential is probed from different perspectives. The CMB is cross-correlated with different large-scale structure (LSS) tracers: radio sources from the NVSS catalogue; galaxies from the optical SDSS and the infrared WISE surveys; and the Planck 2015 convergence lensing map. The joint cross-correlation of the CMB with the tracers yields a detection at 4σ where most of the signal-to-noise is due to the Planck lensing and the NVSS radio catalogue. In fact, the ISW effect is detected from the Planck data only at ≈3σ (through the ISW-lensing bispectrum), which is similar to the detection level achieved by combining the cross-correlation signal coming from all the galaxy catalogues mentioned above. We study the ability of the ISW effect to place constraints on the dark-energy parameters; in particular, we show that ΩΛ is detected at more than 3σ. This cross-correlation analysis is performed only with the Planck temperature data, since the polarization scales available in the 2015 release do not permit significant improvement of the CMB-LSS cross-correlation detectability. Nevertheless, the Planck polarization data are used to study the anomalously large ISW signal previously reported through the aperture photometry on stacked CMB features at the locations of known superclusters and supervoids, which is in conflict with ΛCDM expectations. We find that the current Planck polarization data do not exclude that this signal could be caused by the ISW effect. In addition, the stacking of the Planck lensing map on the locations of superstructures exhibits a positive cross-correlation with these large-scale structures. Finally, we have improved our previous reconstruction of the ISW temperature fluctuations by combining the information encoded in all the previously mentioned LSS tracers. In particular, we construct a map of the ISW secondary anisotropies and the corresponding uncertainties map, obtained from simulations. We also explore the reconstruction of the ISW anisotropies caused by the large-scale structure traced by the 2MASS Photometric Redshift Survey (2MPZ) by directly inverting the density field into the gravitational potential field
Role of lime with cement in long-term strength of Compressed Stabilized Earth Blocks.

Compressed Stabilized Earth Blocks (CSEBs) are manufactured using stabilizers to provide adequate compressive strength and durability, so, as to make them suitable as building blocks. Though cement is a popular stabilizer used in manufacture of CSEBs, no study has been reported utilizing lime in combination of cement. This experimental study on CSEBs prepared using lime as a replacement to cement in certain proportions has clearly brought out the effectiveness of lime with cement in improving the long-term build-up of strength better than using cement alone. It was observed that blocks prepared with optimum quantity of lime along with cement has led to continuous buildup of strength even beyond 2 years, whereas blocks prepared with cement alone and lesser quantity of lime than optimum quantity have not gained much strength after 6 months from the time of preparation of the blocks. The research findings show a need to relook at the grading of ingredients and quantity of stabilizers for achieving good building blocks. This would be an added benefit not only in reducing the cost of the blocks, but also has serious implications in terms of the reduction of energy consumed in the manufacture of blocks when done in large scale
Search for heavy resonances decaying into a W or Z boson and a Higgs boson in final states with leptons and b-jets in 36 fb−1 of √s=13 TeV pp collisions with the ATLAS detector

A search is conducted for new resonances decaying into a W or Z boson and a 125 GeV Higgs boson in the νν¯¯¯bb¯¯, ℓ±νbb¯¯, and ℓ+ℓ−bb¯¯ final states, where ℓ± = e± or μ±, in pp collisions at s√=13 TeV. The data used correspond to a total integrated luminosity of 36.1 fb−1 collected with the ATLAS detector at the Large Hadron Collider during the 2015 and 2016 data-taking periods. The search is conducted by examining the reconstructed invariant or transverse mass distributions of W h and Zh candidates for evidence of a localised excess in the mass range of 220 GeV up to 5 TeV. No significant excess is observed and the results are interpreted in terms of constraints on the production cross-section times branching fraction of heavy W ′ and Z′ resonances in heavy-vector-triplet models and the CP-odd scalar boson A in two-Higgs-doublet models. Upper limits are placed at the 95% confidence level and range between 9.0 × 10−4 pb and 7.3 × 10−1 pb depending on the model and mass of the resonance
Networking our way to better ecosystem service provision

The ecosystem services (EcoS) concept is being used increasingly to attach values to natural systems and the multiple benefits they provide to human societies. Ecosystem processes or functions only become EcoS if they are shown to have social and/or economic value. This should assure an explicit connection between the natural and social sciences, but EcoS approaches have been criticized for retaining little natural science. Preserving the natural, ecological science context within EcoS research is challenging because the multiple disciplines involved have very different traditions and vocabularies (common-language challenge) and span many organizational levels and temporal and spatial scales (scale challenge) that define the relevant interacting entities (interaction challenge). We propose a network-based approach to transcend these discipline challenges and place the natural science context at the heart of EcoS research.&nbsp
Shaping fission yeast cells by rerouting actin-based transport on microtubules.

Kinesins and myosins transport cargos to specific locations along microtubules and actin filaments, respectively. The relative contribution of the two transport systems for cell polarization varies extensively in different cell types, with some cells relying exclusively on actin-based transport while others mainly use microtubules. Using fission yeast, we asked whether one transport system can substitute for the other. In this organism, microtubules and actin cables both contribute to polarized growth by transporting cargos to cell poles, but with distinct roles: microtubules transport landmarks to label cell poles for growth and actin assembly but do not directly contribute to the growth process [1]. Actin cables serve as tracks for myosin V delivery of growth vesicles to cell poles [2-4]. We engineered a chimera between the motor domain of the kinesin 7 Tea2 and the globular tail of the myosin V Myo52, which we show transports Ypt3, a myosin cargo receptor, to cell poles along microtubules. Remarkably, this chimera restores polarized growth and viability to cells lacking actin cables. It also bypasses the normal microtubule-dependent marking of cell poles for polarized growth, but not for other functions. Thus, a synthetic motor protein successfully redirects cargos along a distinct cytoskeletal route
Subclinical thyroid dysfunction, cardiac function, and the risk of heart failure. The Cardiovascular Health study.

OBJECTIVES: The goal of this study was to determine whether subclinical thyroid dysfunction was associated with incident heart failure (HF) and echocardiogram abnormalities. BACKGROUND: Subclinical hypothyroidism and hyperthyroidism have been associated with cardiac dysfunction. However, long-term data on the risk of HF are limited. METHODS: We studied 3,044 adults&gt;or=65 years of age who initially were free of HF in the Cardiovascular Health Study. We compared adjudicated HF events over a mean 12-year follow-up and changes in cardiac function over the course of 5 years among euthyroid participants, those with subclinical hypothyroidism (subdivided by thyroid-stimulating hormone [TSH] levels: 4.5 to 9.9, &gt;or=10.0 mU/l), and those with subclinical hyperthyroidism. RESULTS: Over the course of 12 years, 736 participants developed HF events. Participants with TSH&gt;or=10.0 mU/l had a greater incidence of HF compared with euthyroid participants (41.7 vs. 22.9 per 1,000 person years, p=0.01; adjusted hazard ratio: 1.88; 95% confidence interval: 1.05 to 3.34). Baseline peak E velocity, which is an echocardiographic measurement of diastolic function associated with incident HF in the CHS cohort, was greater in those patients with TSH&gt;or=10.0 mU/l compared with euthyroid participants (0.80 m/s vs. 0.72 m/s, p=0.002). Over the course of 5 years, left ventricular mass increased among those with TSH&gt;or=10.0 mU/l, but other echocardiographic measurements were unchanged. Those patients with TSH 4.5 to 9.9 mU/l or with subclinical hyperthyroidism had no increase in risk of HF. CONCLUSIONS: Compared with euthyroid older adults, those adults with TSH&gt;or=10.0 mU/l have a moderately increased risk of HF and alterations in cardiac function but not older adults with TSH&lt;10.0 mU/l. Clinical trials should assess whether the risk of HF might be ameliorated by thyroxine replacement in individuals with TSH&gt;or=10.0 mU/l
GRO J1008−57: an (almost) predictable transient X-ray binary

A study of archival RXTE, Swift, and Suzaku pointed observations of the transient high-mass X-ray binary GRO J1008−57 is presented. A new orbital ephemeris based on pulse arrival-timing shows the times of maximum luminosities during outbursts of GRO J1008−57 to be close to periastron at orbital phase − 0.03. This makes the source one of a few for which outburst dates can be predicted with very high precision. Spectra of the source in 2005, 2007, and 2011 can be well described by a simple power law with high-energy cutoff and an additional black body at lower energies. The photon index of the power law and the black-body flux only depend on the 15–50 keV source flux. No apparent hysteresis effects are seen. These correlations allow us to predict the evolution of the pulsar’s X-ray spectral shape over all outbursts as a function of just one parameter, the source’s flux. If modified by an additional soft component, this prediction even holds during GRO J1008−57’s 2012 type II outburst.We acknowledge funding by the Bundesministerium für Wirtschaft und Technologie under Deutsches Zentrum für Luft- und Raumfahrt grants 50OR0808, 50OR0905, 50OR1113, and the Deutscher Akademischer Austauschdienst.

The effect of an intervention to improve newly qualified teachers’ interpersonal style, students motivation and psychological need satisfaction in sport-based physical education

Recent developments in self-determination theory research in the educational setting (e.g., Reeve, Deci, & Ryan, 2004), suggest that teachers’ interpersonal style should be considered as consisting of three dimensions: autonomy-support, structure and interpersonal involvement. Based on this theoretical proposition, the purpose of the present study was to test the effects of a training program for three physical education newly qualified teachers on the aforementioned teachers’ overt behaviors and students’ psychological needs satisfaction, self-determined motivation and engagement in sport-based physical education. After a baseline period of four lessons, the teachers attended an informational session on adaptive student motivation and how to support it. The training program also included individualized guidance during the last four lessons of the cycle. Results revealed that from pre- to post-intervention: (1) teachers managed to improve their teaching style in terms of all three dimensions, and (2) students were receptive to these changes, as shown by increases in their reported need satisfaction, self-determined motivation and engagement in the class
Study of DJ meson decays to D+π−, D0π+ and D∗+π− final states in pp collision

A study of D +π−, D 0π+ and D ∗+π− final states is performed using pp collision data, corresponding to an integrated luminosity of 1.0 fb−1, collected at a centre-of-mass energy of 7 TeV with the LHCb detector. The D 1(2420)0 resonance is observed in the D ∗+π− final state and the D∗2(2460) resonance is observed in the D +π−, D 0π+ and D ∗+π− final states. For both resonances, their properties and spin-parity assignments are obtained. In addition, two natural parity and two unnatural parity resonances are observed in the mass region between 2500 and 2800 MeV. Further structures in the region around 3000 MeV are observed in all the D ∗+π−, D +π− and D 0π+ final states
Numerical computation of 3D heat transfer in complex parallel heat exchangers using generalized Graetz modes

We propose and develop a variational formulation dedicated to the simulation of parallel convective heat exchanger that handles possibly complex  input/output conditions as well as connection between pipes. It is based on a spectral method that allows to re-cast three-dimensional heat exchangers into a two-dimensional eigenvalue problem, named the generalized Graetz problem. Our formulation handles either convective, adiabatic, or prescribed temperature at the entrance or at the exit of the exchanger. This formulation is robust to mode truncation, offering a huge reduction in computational cost, and providing insights into the most contributing structure to exchanges and transfer. Several examples of heat exchangers are analyzed, their numerical convergence is tested and  the numerical efficiency of the approach is illustrated  in the case of Poiseuille flow in tubes
Born-Infeld Determinantal gravity and the taming of the conical
  singularity in 3-dimensional spacetime

In the context of Born-Infeld \emph{determinantal} gravity formulated in a
n-dimensional spacetime with absolute parallelism, we found an exact
3-dimensional \emph{vacuum} circular symmetric solution without cosmological
constant consisting in a rotating spacetime with non singular behavior. The
space behaves at infinity as the conical geometry typical of 3-dimensional
General Relativity without cosmological constant. However, the solution has no
conical singularity because the space ends at a minimal circle that no freely
falling particle can ever reach in a finite proper time. The space is curved,
but no divergences happen since the curvature invariants vanish at both
asymptotic limits. Remarkably, this very mechanism also forbids the existence
of closed timelike curves in such a spacetime.Comment: 6 pages, 2 figures. References added, some discussions improved.

Planar dynamical systems with pure Lebesgue diffraction spectrum

We examine the diffraction properties of lattice dynamical systems of
algebraic origin. It is well-known that diverse dynamical properties occur
within this class. These include different orders of mixing (or higher-order
correlations), the presence or absence of measure rigidity (restrictions on the
set of possible shift-invariant ergodic measures to being those of algebraic
origin), and different entropy ranks (which may be viewed as the maximal
spatial dimension in which the system resembles an i.i.d.\ process). Despite
these differences, it is shown that the resulting diffraction spectra are
essentially indistinguishable, thus raising further difficulties for the
inverse problem of structure determination from diffraction spectra. Some of
them may be resolved on the level of higher-order correlation functions, which
we also briefly compare.Comment: 14 pages, slightly revised versio
Ionisation in atmospheres of Brown Dwarfs and extrasolar planets I The
  role of electron avalanche

Brown Dwarf and extrasolar planet atmospheres form clouds which strongly
influence the local chemistry and physics. These clouds are globally neutral
obeying dust-gas charge equilibrium which is, on short time scales,
inconsistent with the observation of stochastic ionisation events of the solar
system planets. We argue that a significant volume of the clouds in Brown
Dwarfs and extrasolar planets is susceptible to local discharge events. These
are electron avalanches triggered by charged dust grains. Such intra-cloud
discharges occur on time scales shorter than the time needed to neutralise the
dust grains by collisional processes. An ensemble of discharges is likely to
produce enough free charges to suggest a partial and stochastic coupling of the
atmosphere to a large-scale magnetic field.Comment: 18 pages in referee's style, 5 figures, Acccepted by Ap
Bifurcation and stability for Nonlinear Schroedinger equations with
  double well potential in the semiclassical limit

We consider the stationary solutions for a class of Schroedinger equations
with a symmetric double-well potential and a nonlinear perturbation. Here, in
the semiclassical limit we prove that the reduction to a finite-mode
approximation give the stationary solutions, up to an exponentially small term,
and that symmetry-breaking bifurcation occurs at a given value for the strength
of the nonlinear term. The kind of bifurcation picture only depends on the
non-linearity power. We then discuss the stability/instability properties of
each branch of the stationary solutions. Finally, we consider an explicit
one-dimensional toy model where the double well potential is given by means of
a couple of attractive Dirac's delta pointwise interactions.Comment: 46 pages, 4 figure
From localization to delocalization in the quantum Coulomb glass

We numerically investigate how electron-electron interactions influence the
transport properties of disordered electrons in two dimensions. Our study is
based on the quantum Coulomb glass model appropriately generalized to include
the spin degrees of freedom. In order to obtain the low-energy properties of
this model we employ the Hartree-Fock based diagonalization, an efficient
numerical method similar to the configuration interaction approach in quantum
chemistry. We calculate the d.c. conductance by means of the Kubo-Greenwood
formula and pay particular attention to the spin degrees of freedom. In
agreement with earlier results we find that electron-electron interactions can
cause delocalization. For spinful electrons this delocalization is
significantly larger than for spinless electrons.Comment: 5 pages, 1 EPS figure, Proceedings of "Hopping and Related Phenomena

Dynamical Systems, Topology and Conductivity in Normal Metals in strong
  magnetic fields

We represent here the full description of all asymptotic regimes of
conductivity behavior in the so-called "Geometric Strong Magnetic Field limit"
in the 3D single crystal normal metals with topologically complicated Fermi
surfaces. In particular, new observable integer-valued characteristics of
conductivity of the topological origin were introduced by the present authors
few years ago; they are based on the Topological Resonance found by the present
authors and play the basic role in the total picture. Our investigation is
based on the study of dynamical systems on Fermi surfaces for the
semi-classical motion of electron in magnetic field realized by the Moscow
topological group.Comment: 22 pages, 5 eps-figures, Late
Sound Propagation and Transport Properties of Liquid $^3$He in Aerogel

Superfluid $^3$He confined in aerogel offers a unique chance to study the
effects of a short mean free path on the properties of a well defined
superfluid Fermi liquid with anisotropic pairing. Transport coefficients and
collective excitations, e.g. longitudinal sound, are expected to react
sensitively to a short mean free path and to offer the possibility for testing
recently developed models for quasiparticle scattering at aerogel strands.
Sound experiments, together with a theoretical analysis based on Fermi liquid
theory for systems with short mean free paths, should give valuable insights
into the interaction between superfluid $^3$He and aerogel.Comment: 7 pages in Latex (JLTP style) with 4 figures (postscript). To appear

Observable Neutron-Antineutron Oscillations in Seesaw Models of Neutrino
  Mass

We show that in a large class of supersymmetric models with spontaneously
broken B-L symmetry, neutron--antineutron oscillations occur at an observable
level even though the scale of B-L breaking is very high, v_{B-L} ~ 2 x 10^{16}
GeV, as suggested by gauge coupling unification and neutrino masses. We
illustrate this phenomenon in the context of a recently proposed class of
seesaw models that solves the strong CP problem and the SUSY phase problem
using parity symmetry. We obtain an upper limit on N-\bar{N} oscillation time
in these models, \tau_{N-\bar{N}} < 10^{9} -10^{10} sec. This suggests that a
modest improvement in the current limit on \tau_{N-\bar{N}} of 0.86 x 10^8 sec
will either lead to the discovery of N-\bar{N} oscillations, or will
considerably restrict the allowed parameter space of an interesting class of
neutrino mass models.Comment: 11 pages RevTeX, 1 figur
Fast and accurate $G^1$ fitting of clothoid curves

A new effective solution to the problem of Hermite $G^1$ interpolation with a
clothoid curve is here proposed, that is a clothoid that interpolates two given
points in a plane with assigned unit tangent vectors. The interpolation problem
is a system of three nonlinear equations with multiple solutions which is
difficult to solve also numerically. Here the solution of this system is
reduced to the computation of the zeros of one single function in one variable.
The location of the zero associated to the relevant solution is studied
analytically: the interval containing the zero where the solution is proved to
exists and to be unique is provided. A simple guess function allows to find
that zero with very few iterations in all possible configurations.
  The computation of the clothoid curves and the solution algorithm call for
the evaluation of Fresnel related integrals. Such integrals need asymptotic
expansions near critical values to avoid loss of precision. This is necessary
when, for example, the solution of the interpolation problem is close to a
straight line or an arc of circle. A simple algorithm is presented for
efficient computation of the asymptotic expansion.
  The reduction of the problem to a single nonlinear function in one variable
and the use of asymptotic expansions make the present solution algorithm fast
and robust. In particular a comparison with algorithms present in literature
shows that the present algorithm requires less iterations. Moreover accuracy is
maintained in all possible configurations while other algorithms have a loss of
accuracy near the transition zones.Comment: 23 pages, 9 figures. arXiv admin note: text overlap with
