CALIFA, the Calar Alto Legacy Integral Field Area Survey IV. Third public data release

This paper describes the third public data release (DR3) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. Science-grade quality data for 667 galaxies are made public, including the 200 galaxies of the second public data release (DR2). Data were obtained with the integral field spectrograph PMAS/PPak mounted on the 3.5 m telescope at the Calar Alto Observatory. Three different spectral setups are available: i) a low-resolution V500 setup covering the wavelength range 3745-7500 angstrom (4240-7140 angstrom unvignetted) with a spectral resolution of 6.0 angstrom (FWHM) for 646 galaxies, ii) a medium-resolution V1200 setup covering the wavelength range 3650-4840 angstrom (3650-4620 angstrom unvignetted) with a spectral resolution of 2.3 angstrom (FWHM) for 484 galaxies, and iii) the combination of the cubes from both setups (called COMBO) with a spectral resolution of 6.0 angstrom and a wavelength range between 3700-7500 angstrom (3700-7140 angstrom unvignetted) for 446 galaxies. The Main Sample, selected and observed according to the CALIFA survey strategy covers a redshift range between 0.005 and 0.03, spans the color-magnitude diagram and probes a wide range of stellar masses, ionization conditions, and morphological types. The Extension Sample covers several types of galaxies that are rare in the overall galaxy population and are therefore not numerous or absent in the CALIFA Main Sample. All the cubes in the data release were processed using the latest pipeline, which includes improved versions of the calibration frames and an even further improved image reconstruction quality. In total, the third data release contains 1576 datacubes, including-1.5 million independent spectra
Azimuthal decorrelation of jets widely separated in rapidity in pp collisions at sqrt(s) = 7 TeV

The decorrelation in the azimuthal angle between the most forward and the most backward jets (Mueller-Navelet jets) is measured in data collected in pp collisions with the CMS detector at the LHC at s√=7 TeV. The measurement is presented in the form of distributions of azimuthal-angle differences, Δϕ, between the Mueller-Navelet jets, the average cosines of (π − Δϕ), 2(π − Δϕ), and 3(π − Δϕ), and ratios of these cosines. The jets are required to have transverse momenta, pT, in excess of 35 GeV and rapidities, |y|, of less than 4.7. The results are presented as a function of the rapidity separation, Δy, between the Mueller-Navelet jets, reaching Δy up to 9.4 for the first time. The results are compared to predictions of various Monte Carlo event generators and to analytical predictions based on the DGLAP and BFKL parton evolution schemes
Counting statistics for genetic switches based on effective interaction
  approximation

Applicability of counting statistics for a system with an infinite number of
states is investigated. The counting statistics has been studied a lot for a
system with a finite number of states. While it is possible to use the scheme
in order to count specific transitions in a system with an infinite number of
states in principle, we have non-closed equations in general. A simple genetic
switch can be described by a master equation with an infinite number of states,
and we use the counting statistics in order to count the number of transitions
from inactive to active states in the gene. To avoid to have the non-closed
equations, an effective interaction approximation is employed. As a result, it
is shown that the switching problem can be treated as a simple two-state model
approximately, which immediately indicates that the switching obeys non-Poisson
statistics.Comment: 6 pages, 2 figure
Career development learning: maximising the contribution of work-integrated learning to the student experience. Final project report June 2009

All Australian universities provide work-integrated learning of some type in their academic programs. Universities Career Services have historically played a significant role in the delivery of work-integrated learning. However, the extent and manner in which career development learning, as a pedagogical framework, has been embedded in the work-integrated learning experiences of students has been unclear. Furthermore, the extent to which Career Services and other university departments which deliver work-integrated learning interact and cooperate with one another in their separate or joint delivery of work-integrated learning varies across the sector. Accordingly, the National Association of Graduate Careers Advisory Services (NAGCAS) secured project funding from the Australian Learning and Teaching Council (ALTC) to investigate career development learning services and strategies that contribute to and enhance the outcomes of work integrated learning in university programs. \ud
This project focused on the career development learning experience of Australian university students and graduates, and the provision of educational services and experiences that enhance and improve career development learning. Within this parameter, work-integrated learning is taken to be an educational vehicle or portal for the direct or indirect provision of services and experiences that contribute to career development learning. In summary, the project aims included:\ud
1. scoping the relationship between career development learning and work-integrated learning in higher education;\ud
2. producing an analysis of how the two could be integrated and synergized; and\ud
3. producing learning resources to support university staff and employers in their delivery of career development learning and work-integrated learning.\u
Optokinetic behavior is reversed in achiasmatic mutant zebrafish larvae.

The vertebrate optokinetic nystagmus (OKN) is a compensatory oculomotor behavior that is evoked by movement of the visual environment. It functions to stabilize visual images on the retina. The OKN can be experimentally evoked by rotating a drum fitted with stripes around the animal and has been studied extensively in many vertebrate species, including teleosts. This simple behavior has earlier been used to screen for mutations affecting visual system development in the vertebrate model organism zebrafish. In such a screen, we have found a significant number of homozygous belladonna (bel) mutant larvae to be defective in the correct execution of the OKN [1]. We now show that about 40% of homozygous bel larvae display a curious reversal of the OKN upon visual stimulation. Monocular stimulation leads to primary activation of ipsilateral eye movements in larvae that behave like the wild type. In contrast, affected larvae display contralateral activation of eye movements upon monocular stimulation. Anatomical analysis of retinal ganglion cell axon projections reveal a morphological basis for the observed behavioral defect. All animals with OKN reversal are achiasmatic. Further behavioral examination of affected larvae show that OKN-reversed animals execute this behavior in a stimulus-velocity-independent manner. Our data support a parsimonious model of optokinetic reversal by the opening of a controlling feedback loop at the level of the optic chiasm that is solely responsible for the observed behavioral abnormality in mutant belladonna larvae
Sequential multiphoton strategy for semiconductor-based terahertz detectors

A semiconductor-based terahertz-detector strategy, exploiting a bound-to-bound-to-continuum architecture, is presented and investigated. In particular, a ladder of equidistant energy levels is employed, whose step is tuned to the desired detection frequency and allows for sequential multiphoton absorption. Our theoretical analysis demonstrates that the proposed multisubband scheme could represent a promising alternative to conventional quantum-well infrared photodetectors in the terahertz spectral regio
The development and evaluation of Cryptophlebia Leucotreta granulovirus (CrleGV) as a biological control agent for the management of false codling moth, Cryptophlebia Leucotreta, on citrus

A granulovirus isolated from Cryptophlebia leucotreta larvae was shown through restriction endonuclease analysis to be a novel strain (CrleGV-SA). No more than one isolate could be identified from a laboratory culture of C. leucotreta. However, a preliminary examination of restricted DNA profiles of isolates from different geographical regions indicated some minor differences. In surface dose bioassays on artificial diet, LC50 and LC90 values with neonate larvae were estimated to be 4.095 x 103 OBs/ml and 1.185 x 105 OBs/ml respectively. LT50 and LT90
values with neonate larvae were estimated to be 4 days 22 h and 7 days 8 h, respectively.
Detached fruit (navel orange) bioassays with neonate larvae indicated that virus concentrations that are likely to be effective in the field range from 1.08 x 107 to 3.819 x 1010 OBs/ml. In surface dose bioassays with fifth instar larvae LC50 and LC90 values were estimated to be 2.678 x
107 OBs/ml and 9.118 x 109 OBs/ml respectively. LT50 and LT90 values were estimated to be 7 days 17 h and 9 days 8 h, respectively. A new artificial diet for mass rearing the host was developed. Microbial contamination of diet was significantly reduced by adding nipagin and sorbic acid to the diet and by surface sterilising C. leucotreta eggs with Sporekill. Almost 20 % more eggs were produced from moths reared on the new diet compared to moths reared on the old
diet. A further 9 % improvement in egg production and a reduction in the labour required to produce eggs, was made with the development of a new oviposition cage attached to the moth eclosion box. Virus was mass produced in fifth instar C. leucotreta larvae by surface inoculating diet with the LC90. When 300 individuals were placed onto inoculated diet, 56 % of them were recovered six to 11 days later as infected larvae. Mean larval equivalents was 1.158 x 1011 OBs/larva. When larvae and diet were harvested together, highest yields of virus were achieved at eight days after inoculation. Microbial contamination in semi-purified preparations of CrleGV ranged from 176211 to 433594 (OB:CFU ratio). Half-life of CrleGV in the field was estimated to be less than 1 day on the northern aspect of trees and between 3 - 6 days on the southern aspect.
Original activity remaining (OAR) of the virus dropped below 50 % after 5 days on the northern aspect of trees and was still at 69 % on the southern aspect of trees after 3 weeks. In field trials, CrleGV reduced C. leucotreta infestation of navel oranges by up to 60 % for a period of 39 days.
CrleGV in combination with augmentation of the C. leucotreta egg parasitoid, Trichogrammatoidea cryptophlebiae, reduced infestation by 70 %. The integration of CrleGV into an integrated pest management (IPM) system for the management of C. leucotreta on citrus
is proposed.
Tax decentralization and public deficits in OECD countries

This article explores the effect of sub-national tax autonomy and sub-national control over shared taxes on primary deficits with panel data for 23 OECD countries over the 1975-2000 period. The results suggest that sub-national tax autonomy has a U-shaped effect on primary deficits. We find that the “average” country in the sample could increase the fiscal stability of its public sector by reducing sub-national tax autonomy. There is also some indication that subnational control over shared taxes increases fiscal stability, but we obtain this result only if Belgium and Spain are included in the sample.
Aggregation of concentrated colloidal silica dispersions in flow

Concentrated suspensions of nanoparticles subjected to transport or shear forces are commonly encountered in many processes such as precipitation, wet comminution or filtration. In these processes, particles are likely to undergo processes of aggregation and fragmentation under physicochemical interactions and hydrodynamic forces. This study is focused on the analysis of the behaviour of colloidal silica in dense suspensions subjected to hydrodynamic forces.\ud
The destabilization of a colloidal silica suspension is done adding sodium chloride salt to a stable dispersion, so modifying the ionic force of the system. Batch experiments, performed in an agitated vessel, were made in order to observe the behaviour of the suspended particles under fixed operational parameters. Various techniques of characterization of the particle size (photon correlation spectroscopy, acoustic spectroscopy) and of the physicochemical properties of the suspensions were used allowing defining the silica dispersions properties (particle size distribution, particle arrangement during the aggregation process, pH, zeta potential). This work presents a study of on-line particle sizing during the aggregation process of colloidal silica by ultrasonic attenuation spectroscopy.\ud
The evolution of the particle size distribution versus time showed the different stages of the silica aggregation whose kinetic rates depend either on physicochemical or hydrodynamics parameters
Collider production of Electroweak resonances from photon-photon states

We estimate production cross sections for 2-body resonances of the
Electroweak Symmetry Breaking sector (in $W_LW_L$ and $Z_LZ_L$ rescattering)
from $\gamma\gamma$ scattering. We employ unitarized Higgs Effective Field
Theory amplitudes previously computed coupling the two photon channel to the
EWSBS. We work in the Effective Photon Approximation and examine both $e^-e^+$
collisions at energies of order 1-2 TeV (as relevant for future lepton
machines) and $pp$ collisions at LHC energies. Dynamically generating a spin-0
resonance around 1.5 TeV (by appropriately choosing the parameters of the
effective theory) we find that the differential cross section per unit $s$,
$p_t^2$ is of order 0.01 fbarn/TeV$^4$ at the LHC. Injecting a spin-2 resonance
around 2 TeV we find an additional factor 100 suppression for $p_t$ up to 200
GeV. The very small cross sections put these $\gamma\gamma$ processes, though
very clean, out of reach of immediate future searches.Comment: 36 pages, 20 plot
Measurement of quarkonium production cross sections in pp collisions at
  $\sqrt{s}=$ 13 TeV

Differential production cross sections of J/$\psi$ and $\psi$(2S) charmonium
and $\Upsilon$(nS) (n = 1, 2, 3) bottomonium states are measured in
proton-proton collisions at $\sqrt{s} =$ 13 TeV, with data collected by the CMS
detector at the LHC, corresponding to an integrated luminosity of 2.3 fb$^{-1}$
for the J/$\psi$ and 2.7 fb$^{-1}$ for the other mesons. The five quarkonium
states are reconstructed in the dimuon decay channel, for dimuon rapidity $|y|
<$ 1.2. The double-differential cross sections for each state are measured as a
function of $y$ and transverse momentum, and compared to theoretical
expectations. In addition, ratios are presented of cross sections for prompt
$\psi$(2S) to J/$\psi$, $\Upsilon$(2S) to $\Upsilon$(1S), and $\Upsilon$(3S) to
$\Upsilon$(1S) production.Comment: Replaced with the published version. Added the journal reference. All

Parental health limitations, caregiving and loneliness among women with widowed parents: longitudinal evidence from France

We investigate how daughters’ feelings of loneliness are impacted when widowed parents develop health limitations, and when daughters take on personal care tasks in response. Using longitudinal data from daughters of widowed parents drawn from the French Family and Intergenerational Relationships Study (ERFI, 1485 observations nested in 557 daughters), we assess (a) whether health limitations of widowed parents are associated with daughters’ feelings of loneliness regardless of whether or not daughters provide personal care and (b) whether there is an effect of care provision on loneliness that cannot be explained by parental health limitations. Fixed effect regression analyses show that widowed parents’ health limitations were associated with raised feelings of loneliness among their daughters. No significant additional effect of providing personal care to a widowed parent was found. Prior research on the impact of health limitations of older parents on the lives of their adult–children has focused mostly on issues related to informal caregiving. Our findings suggest that more attention to the psychosocial impact of parental health limitations—net of actual caregiving—on adult children’s lives is warrante
More than counting pixels - perspectives on the importance of remote sensing training in ecology and conservation

As remote sensing (RS) applications and resources continue to expand, their importance for ecology and conservation increases – and so does the need for effective and successful training of professionals working in those fields. Methodological and applied courses often form part of university curricula, but their practical and long-term benefits only become clear afterwards. Having recently received such training in an interdisciplinary master’s programme, we provide our perspectives on our shared education. Through an online survey we include experiences of students and professionals in different fields. Most participants perceive their RS education as useful for their career, but express a need for more training at university level. Hands-on projects are considered the most effective learning method. Besides methodological knowledge, soft skills are clear gains, including problem solving, self-learning and finding individual solutions, and the ability to work in interdisciplinary teams. The largest identified gaps in current RS training concern the application regarding policy making, methodology and conservation. To successfully prepare students for a career, study programmes need to provide RS courses based on state-of-the-art methods, including programming, and interdisciplinary projects linking research and practice supported by a sound technical background
Spots & stripes: pleomorphic patterning of stem cells via p-ERK-depenendent cell chemotaxis shown by feather morphogenesis & mathematical simulation

A key issue in stem cell biology is the differentiation of homogeneous stem cells towards different fates which are also organized into desired configurations. Little is known about the mechanisms underlying the process of periodic patterning. Feather explants offer a fundamental and testable model in which multi-potential cells are organized into hexagonally arranged primordia and the spacing between primordia. Previous work explored roles of a Turing reaction–diffusion mechanism in establishing chemical patterns. Here we show that a continuum of feather patterns, ranging from stripes to spots, can be obtained when the level of p-ERK activity is adjusted with chemical inhibitors. The patterns are dose-dependent, tissue stage-dependent, and irreversible. Analyses show that ERK activity-dependent mesenchymal cell chemotaxis is essential for converting micro-signaling centers into stable feather primordia. A mathematical model based on short-range activation, long-range inhibition, and cell chemotaxis is developed and shown to simulate observed experimental results. This generic cell behavior model can be applied to model stem cell patterning behavior at large
Detection of respiratory bacterial pathogens causing atypical pneumonia by multiplex Lightmix : javax.xml.bind.JAXBElement@40a302e0 : RT-PCR.

Pneumonia is a severe infectious disease. In addition to common viruses and bacterial pathogens (e.g. Streptococcus pneumoniae), fastidious respiratory pathogens like Chlamydia pneumoniae, Mycoplasma pneumoniae and Legionella spp. can cause severe atypical pneumonia. They do not respond to penicillin derivatives, which may cause failure of antibiotic empirical therapy. The same applies for infections with B. pertussis and B. parapertussis, the cause of pertussis disease, that may present atypically and need to be treated with macrolides. Moreover, these fastidious bacteria are difficult to identify by culture or serology, and therefore often remain undetected. Thus, rapid and accurate identification of bacterial pathogens causing atypical pneumonia is crucial. We performed a retrospective method evaluation study to evaluate the diagnostic performance of the new, commercially available Lightmix javax.xml.bind.JAXBElement@6a5abc82 multiplex RT-PCR assay that detects these fastidious bacterial pathogens causing atypical pneumonia. In this retrospective study, 368 clinical respiratory specimens, obtained from patients suffering from atypical pneumonia that have been tested negative for the presence of common agents of pneumonia by culture and viral PCR, were investigated. These clinical specimens have been previously characterized by singleplex RT-PCR assays in our diagnostic laboratory and were used to evaluate the diagnostic performance of the respiratory multiplex Lightmix javax.xml.bind.JAXBElement@7dc63eef RT-PCR. The multiplex RT-PCR displayed a limit of detection between 5 and 10 DNA copies for different in-panel organisms and showed identical performance characteristics with respect to specificity and sensitivity as in-house singleplex RT-PCRs for pathogen detection. The Lightmix javax.xml.bind.JAXBElement@2895e821 multiplex RT-PCR assay represents a low-cost, time-saving and accurate diagnostic tool with high throughput potential. The time-to-result using an automated DNA extraction device for respiratory specimens followed by multiplex RT-PCR detection was below 4 h, which is expected to significantly improve diagnostics for atypical pneumonia-associated bacterial pathogens
CAinterprTools : an R package to help interpreting correspondence analysis’ results

Correspondence Analysis (CA) is a statistical exploratory technique frequently used in many research fields to graphically visualize the structure of contingency tables. Many programs, both commercial and free, perform CA but none of them as yet provides a visual aid to the interpretation of the results. The ‘CAinterprTools’ package, designed to be used in the free R statistical environment, aims at filling that gap. A novel-to-medium R user has been considered as target. 15 commands enable to easily obtain charts that help (and are relevant to) the interpretation of the CA’s results, freeing the user from the need to inspect and scrutinize tabular CA outputs, and to look up values and statistics on which further calculations are necessary. The package also implements tests to assess the significance of the input table’s total inertia and individual dimensions.peer-reviewe
Search for W′ → tb in proton-proton collisions at √s = 8 TeV

A search is performed for the production of a massive W′ boson decaying to a top and a bottom quark. The data analysed correspond to an integrated luminosity of 19.7 fb[superscript −1] collected with the CMS detector at the LHC in proton-proton collisions at √s = 8 TeV. The hadronic decay products of the top quark with high Lorentz boost from the W′ boson decay are detected as a single top flavoured jet. The use of jet substructure algorithms allows the top quark jet to be distinguished from standard model QCD background. Limits on the production cross section of a right-handed W′ boson are obtained, together with constraints on the left-handed and right-handed couplings of the W′ boson to quarks. The production of a right-handed W′ boson with a mass below 2.02 TeV decaying to a hadronic final state is excluded at 95% confidence level. This mass limit increases to 2.15 TeV when both hadronic and leptonic decays are considered, and is the most stringent lower mass limit to date in the tb decay mode. Keywords:
